     BACKGROUND OF THE INVENTION 
     The present invention generally relates to the collection of cut material from a rongeur and, in particular, the collection of bone from a kerrison rongeur. 
     Rongeurs are surgical instruments for the cutting away of human tissue, and most commonly, cartilage and/or bone. “Kerrison” rongeurs are utilized in spinal surgery to remove bone and to thereby gain access to the spinal canal, and are well-known within conventional medical knowledge. Patent references disclosing and discussing kerrison rongeurs and their use in surgery include U.S. Pat. 3,902,498; 5,026,375; 4,722,338; 4,777,940; 4,777,948 and U.S. Pat. applIcation Publication 2003/0216740. 
     With reference to  FIG.  1   a   , an exemplary prior art kerrison rongeur is illustrated. The kerrison rongeur includes a first jaw member  10  that slides parallel to line A relative to, and on top of, a second jaw member  20 . The first jaw member  10  included a distal cutting end having a cutting edge  15 . The second jaw member  20  includes a stop  40  for placement beneath the tissue to be cut, which is generally bone or cartilage. A cutting area  30  is defined between the cutting edge  15  of the first jaw member  10  and the stop  40  of the second jaw member  20 . The first jaw member  10  includes an open, interior cross-section defining an enclosed area within which the bone tissue is received when cut. Such an exemplary cross-section is illustrated in  FIG.  1   b   . As illustrated, the cross-section of the first jaw member  10  has a generally inverted U shape. 
     In an exemplary use of a kerrison rongeur, a surgeon places the bone to be cut, such as the leading edge of the lamina of a vertebra, within the open portion of the distal end of the rongeur. The surgeon then squeezes the handle of the rongeur, which advances a moveable jaw member of the rongeur through and amputates a portion of bone. A surgeon may wait until the jaw member becomes full of bone, at which time the rongeur must be completely removed from the surgical site and passed to a scrub nurse or assisting technician for bone removal. The removal from the instrument of the cut portion of bone often requires that the scrub nurse or assisting technician use a small rigid hook, or toothed forceps, and often further requires that the physician temporarily relinquish the instrument entirely to make such bone removal possible. Once cleaned, the instrument is returned to the surgeon who, in returning it to the surgical site, must then reorient himself to the task at hand. This sequence must then be repeated over and over again. Moreover, in a typical spinal fusion, this sequence may require as many as 50 to  100  such repetitions. 
     Alternatively, a surgeon may present the distal end of the rongeur to a scrub nurse or assisting technician after each cut for removal of the bone, thereby avoiding bone build-up within the jaw member of the rongeur. This can be done without the surgeon relinquishing the rongeur and without the surgeon removing his or her attention and focus from the surgical site. Conventionally, the scrub nurse or assisting technician manually swipes the end of the kerrison rongeur with a sterile material for removing the cut bone. The scrub nurse or assisting technician may repeat the swiping of the cut bone multiple times before harvesting the swiped bone from the material used to perform the swiping. A gauze sponge may be used for swiping. Rather than swiping the bone from the rongeur, a gloved hand may be used by the scrub nurse or assisting technician to directly remove the bone from the rongeur. Thereafter, the harvested bone from the patient may be used in the surgical procedure on the patient, e.g., in autografts. 
     In view of the foregoing, it is believed that a need exists for a safe, expedient, and efficient way for the cut bone to be removed from the kerrison rongeur and harvested by a scrub nurse or assisting technician. This and other needs are believed to be addressed by one or more aspects and features of the invention.

     DETAILED DESCRIPTION 
     As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention. 
     Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention in any claim of a patent issuing here from, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself. 
     Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the issued claim(s) rather than the description set forth herein. 
     Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term— differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail. 
     Regarding applicability of 35 U.S.C. §112(f), no claim element is intended to be read in accordance with this statutory provision unless the explicit phrase “means for” or “step for” is actually used in such claim element, whereupon this statutory provision is intended to apply in the interpretation of such claim element. 
     Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.” 
     When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.” 
     Additionally, as used herein, “cap” denotes “a lid configured to be attached to an object in covering relation to an interior containment space of the object”. 
     As used herein, a “scraper” is a brush, a group of bristles, a protuberance, a barb, or a finger; and is sufficiently rigid so as to generally hold form when not engaged by the distal end of a kerrison rongeur and to generally dislodge bone found in a cutting area of a kerrison rongeur when moved into or through the cutting area. Preferably, a scraper also is sufficiently flexible and resilient so as to generally deflect and bend to some extent upon abutment by and engagement with the distal end of a kerrison rongeur. A scraper may be relatively hard or soft within this range. Furthermore, a scraper preferably comprises a bio-absorbable material in at least some embodiments of the invention. In this respect, a scraper may comprise a brush with bio-absorbable bristles which, if inserted into the body, are absorbed by the body. 
     Referring now to the drawings, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its implementations, or uses. 
     A First Embodiment 
     Accordingly, a perspective view of a collector  100  used to collect cut bone from a kerrison rongeur is shown in  FIG.  2   a   . The collector  100  is in accordance with a first embodiment of the present invention and is illustrated in a generally vertical orientation in  FIG.  2   a   . A perspective view of a sequence of steps for using the collector  100  in collecting bone from a kerrison rongeur is represented in  FIG.  2   b   , in which figure the collector  100  is illustrated in a generally horizontal orientation. 
     As will be appreciated, the collector  100  is hand-held and comprises a container body  101  (shown in  FIG.  2   a    and  FIG.  2   b    to be a generally elongate body or tube that is cylindrical in shape), and having opposite, axially-aligned end caps  102 , 104 . The container body  101  defines an interior containment space and comprises an opaque wall portion  103  and a transparent wall portion  105 . 
     In use, the collector  100  is manually held at opposite ends in a generally horizontal position, as shown in  FIG.  2   b   , in which it is positioned to receive the distal end  108  of a kerrison rongeur containing cut bone  110 . The distal end  108  is received through an intake port opening  106  that is located in side wall portion  103  halfway in-between the opposite ends of the collector  100 . In this respect, the collector  100  is held sideways and is said to be side-loaded. 
     Preferably in use, a scrub nurse, assisting technician, or similar person (hereinafter generally “assistant”) moves or loads the collector  100  onto the distal end  108  of the kerrison rongeur when extended from the surgical site by the surgeon, who preferably maintains focus and attention on the surgical site and does not look away for purposes of aligning the distal end  108  with the intake port opening  106  (which alignment is the assistant’s responsibility); it will be appreciated that the intake port opening  106  is maneuvered relative to and aligned with the distal end  108  by the assistant. 
     Upon receipt of the distal end  108  with the cut bone  110  through the opening  106  into the interior of the collector  100 , the assistant depresses (pushes inwardly in direction of arrows A) on spring-loaded, axially-aligned end buttons  112 , 114  located on the opposite end caps  102 , 104  of the collector  100 , respectively. In this respect, the buttons preferably are urged or biased by springs (not visible in  FIGS.  2   a  or  2   b   ) in directions opposite to the arrows A in  FIG.  2   a    so as to extend outwardly from the body  101  for grasping and holding of the collector  100  by the assistant during maneuvering of the collector onto the distal end  108  of the kerrison rongeur. This causes opposed interior scrapers  116 , 118  located in the interior of the collector  100  and connected to the end caps  102 , 104  to converge onto and cover the distal end  108  of the kerrison rongeur when received within the interior of the collector  100  through the port opening  106 . This action—especially when performed multiple times—should serve to dislodge the bone  110  from the kerrison rongeur, resulting in the bone  110  either becoming lodged within the scrapers or falling onto an interior wall of the collector  100  defining at least in part the interior containment space. Moreover, the scrapers  116 , 118  optionally may be rotatable about a longitudinal axis L of the container body  101  by respective manual rotation of the end buttons  112 , 114 . The transparency of the wall portion  105  will enable the assistant to view whether the bone  110  has been collected yet from the kerrison rongeur, and to continue actuating the end buttons  112 , 114  either until the bone  110  has been collected or a reasonable number of attempts has been tried. 
     Once collected, the assistant removes (unloads) the collector  100  from the distal end  108  of the kerrison rongeur with the bone  110  remaining within the interior of the collector  100 , either loosely retained therein or lodged within one of the opposed scrapers  116 , 118 . Preferably the assistant then acknowledges to the surgeon the completion of the collection of the bone from kerrison rongeur, whereupon the surgeon returns the kerrison rongeur to the surgical site for continued cutting. This sequence continues until cutting by the surgeon is completed. 
     During the procedure, the bone  110  may be kept within the collector  100  until needed or may be removed as desired. The bone  110  preferably is harvested by removing each of the end caps  102 , 104  from the elongate body  101  of the collector  100 .  FIG.  2   c    is a perspective view of a scraper  118  of an end cap  114  of the collector  100  after bone has been collected from a kerrison rongeur and the end cap  114  has been detached from the body  101 . In this respect, each of the end caps  112 , 114  preferably is received within an end of the elongate body  101  and retained thereby by a friction fit, for example, between the wall of the body  101  and a rubber or silicone seal  115 ; and/or a threaded engagement by screwing (not shown). Bone that is lodged within a scraper  116 , 118  of an end cap  102 , 104  can be removed by manually agitating the scraper  116 , 118  and pulling on the bone, with the scraper  116 , 118  extending over a sterile cloth, towel, pad, or table surface to catch the falling bone. Similarly, the bone within the body  101  of the collector  100  that is loose may be dumped onto a sterile cloth, towel, or pad, or directly onto a sterile surface of a table. The transparent portion  105  of the body  101  further may comprise a hinged or removable panel, by which the interior of the body  101  may be accessed for manual removal of any bone that may become stuck within the interior containment space of the body  101 . The harvested bone then can be used during the procedure, such as for example, in an autograft procedure. 
     The materials from which the components of the collector are made may be any desired, suitable material for use in the foregoing procedure. For instance, a scraper may comprise metal or other rigid or semi-rigid material that is effective in dislodging bone from the distal end of the kerrison rongeur. It is further contemplated that one or more of the materials may be molded from, for example, an inert plastic material. Furthermore, the materials preferably are lightweight such that the collector is readily manipulated by hand. Furthermore, the collector may be disposable, in that the collector may be used during a single medical procedure for a patient and then discarded in accordance with applicable HAZMAT protocols. Alternatively, one or more components of the collector (including all of the components) are designed to and are able to be sterilized for reuse with another patient during another procedure. 
     A Second Embodiment 
       FIG.  3   a    is a perspective view of a collector  200  used to collect cut bone from a kerrison rongeur in accordance with a second embodiment of the present invention. The collector  200  is illustrated in a generally vertical orientation in  FIG.  3   a   . A perspective view of the collector  200  representing a sequence of steps for using the collector  200  to collect bone from a kerrison rongeur is shown in  FIG.  3   b   , wherein the collector  200  is illustrated in a generally horizontal orientation. 
     The collector  200  is hand-held and comprises a container body  201 , shown to be generally cylindrical in shape. The container body  201  defines an interior containment space and includes a transparent sidewall portion  203  through which the interior of the container body  201  is visible. 
     The collector  200  further comprises a cap  205  that is attached to the container body  201 .  FIG.  3   c    is a top plan view of the cap  205  of the collector  200 , and  FIG.  3   d    is a side elevational view of the cap  205  of the collector  200 . 
     The top of the cap  205  includes an intake port opening  213  centrally located in the top of the cap  205 , perhaps as best shown in  FIG.  3   c   . The top of the cap  205  includes a funnel-shaped surface  202  that is radially inclined toward the opening  213 , as perhaps best shown in  FIG.  3   b   . The cap  205  further includes a platform  207  that extends into the interior of the container body  201 , as perhaps best shown in  FIG.  3   b   . The platform  207  includes a stop  209  and scrapers  211 . The scrapers 211—two of which are shown in the figures, but any number of which may be included—extend from the platform and are flexible and resilient, preferably sufficiently rigid or semi-rigid so as to hold form when not engaged by the distal end of a kerrison rongeur and deflecting and bending upon abutment by and engagement with the distal end of a kerrison rongeur. The scrapers  211  may be made from metal or other material, and it is contemplated that a scraper may be made of polypropylene. 
     It will be appreciated that the funnel-shaped top surface  202  of the cap  205  is designed to direct a distal end of a kerrison rongeur toward the opening  213  upon abutment therewith, and the stop  209  is intended to abut and physically preclude further advancement of the distal tip of the kerrison rongeur when received through the opening  213 . 
     The cap  205  is freely rotatable relative to the container body  201 , as indicated by the arrow R in  FIG.  3   b   . Rotation—or twisting—of the cap  205  on the container body  201  is facilitated by external ribs  215  on the side of the cap  205  for manual grasping. Rotation of the cap  205  does not detach the cap  205  from the container body  201 , which preferably is received and held within a mouth of the container body  201  in a frictional fit between the container body and a seal  217  of the cap  205 . The cap  205  preferably is removable by pulling of the cap  205  off of the container body  201  with a reasonable amount of effort. 
     The stop  209  is located at a spacing relative to the opening  213  such that, upon receipt of the distal end of the kerrison rongeur and abutment thereof with the stop  209 , the scrapers  211  extend over and cover the distal end of the kerrison rongeur proximate the cutting area in which cut bone would be found. Furthermore, rotation of the cap results in movement of the scrapers  211  around, about and through the cutting area of the distal end of the kerrison rongeur so as to dislodge and remove for collection any cut bone carried therein. 
     In this respect, the collector  200  is held horizontally generally as shown in  FIG.  3   b   . 
     Preferably in use, an assistant moves or loads the collector  200  onto the distal end of a kerrison rongeur when extended from the surgical site by the surgeon, who preferably maintains focus and attention on the surgical site and does not look away for purposes of aligning the distal end with the intake port opening  213 , which is generally located in the center of the cap  205 . Alignment is the assistant’s responsibility, and it will be appreciated that the intake port opening  213  is maneuvered relative to and aligned with the distal end of the kerrison rongeur by the assistant. The funnel-shaped surface  202  facilitates the alignment with and receipt of the distal tip within the opening  213 . 
     Upon receipt of the distal end of the kerrison rongeur into the interior of the collector  200  and its abutment with the stop  209 , the assistant twists (rotates in direction of arrow R) the cap  205  relative to the container body  201 . This causes the scrapers  211  to engage and remove any cut bone carried by the kerrison rongeur, resulting in the bone either falling onto an interior wall of the container body  201  or becoming lodged within a scraper. Moreover, the transparency of the container body  201  will enable the assistant to view whether the bone has been collected yet from the kerrison rongeur, and to continue twisting the cap  205  on and relative to the container body  201  either until the bone has been collected or a reasonable number of rotations has occurred. 
     Once collected from the kerrison rongeur, the assistant removes (unloads) the collector  200  from the distal end of the kerrison rongeur with the bone remaining within the interior of the collector  200 , either loosely retained therein or lodged within a scraper. Preferably the assistant then acknowledges to the surgeon the completion of the collection of the bone from kerrison rongeur, whereupon the surgeon returns the kerrison rongeur to the surgical site for continued cutting. This sequence continues until cutting by the surgeon is completed. 
     During the procedure, the bone may be kept within the collector  200  until needed or may be removed as desired. The bone preferably is harvested by removing the cap  205  from the container body  201 . Bone that is lodged within a scraper can be removed by manually agitating the scraper and pulling on the bone so that the bone falls onto a sterile cloth, towel, pad, or table surface. The bone within the container body  201  that is loose may be dumped onto the sterile cloth, towel, or pad, or directly onto the sterile surface of the table. Bone within the container body  201  that is not loose may be manually removed. The harvested bone then can be used during the procedure, such as for example, in an autograft procedure. 
     The materials from which the components of the collector are made may be any desired, suitable material for use in the foregoing procedure. For instance, a scraper may comprise metal or other rigid or semi-rigid material that is effective in dislodging bone from the distal end of the kerrison rongeur. It is further contemplated that one or more of the materials may be molded from, for example, an inert plastic material. Furthermore, the materials preferably are lightweight such that the collector is readily manipulated by hand. Furthermore, the collector may be disposable, in that the collector may be used during a single medical procedure for a patient and then discarded. Alternatively, one or more components of the collector (including all of the components) are designed to and are able to be sterilized for reuse with another patient during another procedure. 
     A Third Embodiment 
       FIG.  4   a    is a perspective view illustrating a sequence of steps for using another collector  300  in accordance with a third embodiment of the present invention, wherein the collector  300  is illustrated in a generally horizontal orientation receiving the distal end of a kerrison rongeur.  FIG.  4   b    is a top plan view of the collector  300  and distal tip of the kerrison rongeur of  FIG.  4   a   . The collector  300  and use thereof is similar to collector  200  and its use, with the exception that a cap  305  of the collector includes a cut out  308  in the side thereof by which an assistant may better visualize alignment with and receipt of the distal end of a kerrison rongeur within the intake port opening in the cap  305 , and with the further exception that the cap further does not include a funnel-shaped top surface. 
     A Fourth Embodiment 
       FIG.  5   a    a perspective view of a collector  400  used to collect cut bone from a kerrison rongeur for harvesting in accordance with another embodiment of the present invention, wherein the collector  400  is illustrated in a generally vertical orientation.  FIG.  5   b    is a perspective view representative of a sequence of steps for using the collector  400  in collecting bone from a kerrison rongeur, wherein the collector  400  is illustrated in a generally horizontal orientation with the distal end of the kerrison rongeur being received within the collector  400 . 
     The collector  400  is hand-held and comprises a container body  401 , shown to be generally cylindrical in shape. The container body  401  defines an interior containment space and includes a transparent sidewall portion  403  through which the interior of the container body  401  is visible. The collector  400  further comprises a cap  405  that is attached to the container body  401 . The cap  405  includes an interior ledge  411  that defines an intake port opening  413  through which the distal end of a kerrison rongeur is received. The cap  405  further includes a guide member  417  that projects from the ledge  411  and that is shaped and contoured for receiving and guiding therein a portion of the distal end of the kerrison rongeur. The guide member  417  preferably includes a U-shape configuration, as shown. An saddle member  419  extends from a bottom  409  of the container body  401  and, in conjunction with the guide member  417 , assists in aligning the distal end of the kerrison rongeur for collection of bone, as shown in  FIG.  5   b   . The saddle member  419  preferably includes a C-shape configuration, as shown. 
     A scraper  421  is provided proximate the bottom  409  of the container body  401  and extends toward the saddle member  419  into the cutting area of the distal end of a kerrison rongeur when aligned by the saddle member  419 . The scraper  421  is secured to a base  423  that extends from the side wall  403  of the container body  401  in abutment with the bottom  409  of the container body  401 . Further in this regard, the bottom  409  serves as a stop for the distal end of the kerrison rongeur. 
     The cap  405  is freely rotatable relative to the container body  401 , as indicated by the arrows R in  FIG.  5   b   . Rotation—or twisting—of the cap  405  on the container body  401  is facilitated by external ribs  416  on the side of the cap  405  for manual grasping. Rotation of the cap  405  does not detach the cap  405  from the container body  401 , which preferably is received and held within a mouth of the container body  401  in a frictional fit between the container body and a seal (n0w shown, but similar to seal  217  found in collector  200 ). The cap  405  preferably is removable by pulling of the cap  405  off of the container body  401  with a reasonable amount of effort. 
     The scraper  421  is located at a spacing relative to the saddle member  419  such that, upon receipt of the distal end of the kerrison rongeur and abutment thereof with the bottom  409  serving as a stop, the scraper  411  extends over and covers the distal end of the kerrison rongeur proximate the cutting area thereof in which cut bone would be found. Furthermore, rotation of the container body  401  relative to the cap  405  results in movement of the scraper  421  around, about and through the cutting area of the distal end of the kerrison rongeur so as to dislodge and remove for collection any cut bone carried therein. It will further be appreciated that the saddle member  419  also rotates with the container body  401 , whereas the guide member  417  is an integral molded part of—and remains fixed relative to—the cap  405 . 
     It will further be noted that the cap  405  defines an inner surface  430  that, when the collector is positioned for receiving the distal end of the kerrison rongeur, as shown in  FIG.  5   b   , the inner surface  430  will form a flange that catches bone that may fall from the kerrison rongeur while attempting to receiving the distal end of the kerrison rongeur within the guide member  417  and through the intake opening  413 . 
     Preferably in use, an assistant moves or loads the collector  400  onto the distal end of a kerrison rongeur when extended from the surgical site by the surgeon, who preferably maintains focus and attention on the surgical site and does not look away for purposes of aligning the distal end with the intake port opening  413 , which is generally located in the center of the cap  405 . Alignment is the assistant’s responsibility, and it will be appreciated that the intake port opening  413  is maneuvered relative to and aligned with the distal end of the kerrison rongeur by the assistant. The guide member  417  further aids the assistant in positioning of the distal end of the kerrison rongeur within the saddle member  419  after being inserted through the opening  413 . 
     Upon receipt of the distal end of the kerrison rongeur into the interior of the collector  400  and its abutment with the bottom  409  serving as a stop, the assistant twists (rotates back and forth in the directions of arrows R) the container body  401  relative to the cap  405 . This causes the scraper  421  to engage and remove any cut bone carried by the kerrison rongeur, resulting in the bone either falling onto an interior wall of the container body  401  or becoming lodged within the bristles of the scraper  421 . Moreover, the transparency of the side wall  403  container body  401  enables the assistant to view whether the bone has been collected yet from the kerrison rongeur, and to continue twisting the container body  401  relative to the cap  405  back and forth either until the bone has been collected or a reasonable number of attempts have been made by the assistant. 
     Once collected from the kerrison rongeur, the assistant removes (unloads) the collector  400  from the distal end of the kerrison rongeur with the bone remaining within the interior of the collector  400 , either loosely retained therein or lodged within the bristles. Preferably the assistant then acknowledges to the surgeon the completion of the collection of the bone from kerrison rongeur, whereupon the surgeon returns the kerrison rongeur to the surgical site for continued cutting without taking focus away from the surgical site. This sequence continues until cutting by the surgeon is completed. 
     During the procedure, the bone may be kept within the collector  400  until needed or may be removed as desired. The bone preferably is harvested by removing the cap  405  from the container body  401 . Bone that is lodged within a scraper can be removed by manually agitating the bristles and pulling on the bone so that the bone falls onto a sterile cloth, towel, pad, or table surface. The bone within the container body  401  that is loose may be dumped onto the sterile cloth, towel, or pad, or directly onto the sterile surface of the table. Bone within the container body  401  that is not loose may be manually removed by hand or with an instrument. The harvested bone then can be used during the procedure, such as for example, in an autograft procedure. 
     The materials from which the components of the collector are made may be any desired, suitable material for use in the foregoing procedure. For instance, a scraper may comprise metal or other rigid or semi-rigid material that is effective in dislodging bone from the distal end of the kerrison rongeur. It is further contemplated that one or more of the materials may be molded from, for example, an inert plastic material. Furthermore, the materials preferably are lightweight such that the collector is readily manipulated by hand. Furthermore, the collector may be disposable, in that the collector may be used during a single medical procedure for a patient and then discarded. Alternatively, one or more components of the collector (including all of the components) are designed to and are able to be sterilized for reuse with another patient during another procedure. 
       FIG.  5   c    is a side elevational view of an alternative collector  400 ′ generally similar to the collector  400 , but in which the height of the collector  400 ′ is less than the height of the collector  400  and, thus, the collector  400 ′ has a smaller profile. 
     A Fifth Embodiment 
       FIG.  6   a    is a perspective view of a collector  500  used to collect cut bone from a kerrison rongeur for harvesting in accordance with another embodiment of the present invention, wherein the collector  500  is illustrated in a generally horizontal orientation.  FIG.  6   b    is a side elevational view of the collector  500 . 
     The collector  500  includes a container body  501  that is box-shaped with generally rectangular sides and a cap  505  with generally rectangular sides. The container body  501  defines an interior containment space and preferably includes transparent side walls  503 . The container body  501  is utilized to store collected bone. The cap  505  includes a stop comprising a wall  519  that extends between opposed interior side surfaces of the cap  505  and divides passage through the cap to the interior of the container body  501  into two side passages  508  around opposite sides of the wall  519 . Scrapers  521  are located in front of the wall and extend from one of the interior side surfaces of the cap  505  from to which the wall  519  connects. 
     Preferably in use, an assistant moves or loads the collector  500  onto the distal end of a kerrison rongeur when extended from the surgical site by the surgeon, who preferably maintains focus and attention on the surgical site and does not look away for purposes of aligning the distal end of the kerrison rongeur with the opening in the cap  505 . Alignment is the assistant’s responsibility, and it will be appreciated that the collector  500  is maneuvered relative to and aligned with the distal end of the kerrison rongeur by the assistant such that the distal end of the kerrison rongeur, when received within the cap  505 , will come into abutment with the wall  519  and cease further advancement within the cap  505  toward the container body  501 . The spacing of the wall  519  to the scrapers  521  is such that the scrapers will pass through the cutting area of the distal end of the kerrison rongeur when the collector  500  is moved back and forth in lateral directions relative to the longitudinal extent of the kerrison rongeur. Furthermore, the wall  519  may be maintained in abutment with the tip of the kerrison rongeur during such back and forth movement for proper alignment of the scarpers  521  relative to the cutting area of the kerrison rongeur, thereby facilitating dislodgment of cut bone found in the cutting area by the scrapers  521 . Such back and forth movement is facilitated by longitudinally protruding ribs  515  on the cap  505 , which enable better grasping by hand of the cap  505 . Additionally, one or more ribs 515—such as the middle pair of ribs shown in  FIGS.  6   a  and  6   b   , for example—may be used for sighting by the assistant during loading of the distal end of the kerrison rongeur, as represented by the direction and alignment of arrow A relative to the middle pair of ribs seen in  FIG.  6   b   . 
     Once collected from the kerrison rongeur, the assistant removes (unloads) the collector  500  from the distal end of the kerrison rongeur with the bone remaining within the interior of the cap  505 , either loosely retained therein or lodged within the bristles. Tilting of the collector  500  to a vertical orientation and light shaking of the collector  500  should cause any loose bone collected from the kerrison rongeur to fall through one of the side passages into the container body  501  where the bone yield can be viewed through the transparent walls  503 . 
     Preferably the assistant acknowledges to the surgeon the completion of the collection of the bone from kerrison rongeur, whereupon the surgeon returns the kerrison rongeur to the surgical site for continued cutting without taking focus away from the surgical site. This sequence continues until cutting by the surgeon is completed. 
     During the procedure, the bone may be kept within the container body 5b01 of the collector  500  until needed or may be removed as desired. The bone preferably is harvested by removing the cap  505  from the container body  501 . Bone that is lodged within any bristles of the scrapers  521  can be removed by manually agitating the bristles and pulling on the bone so that the bone falls onto a sterile cloth, towel, pad, or table surface. The bone within the container body  501  that is loose may be dumped onto the sterile cloth, towel, or pad, or directly onto the sterile surface of the table. Bone within the container body  501  that is not loose may be manually removed by hand or with an instrument. The harvested bone then can be used during the procedure, such as for example, in an autograft procedure. 
     The materials from which the components of the collector are made may be any desired, suitable material for use in the foregoing procedure. For instance, a scraper may comprise metal or other rigid or semi-rigid material that is effective in dislodging bone from the distal end of the kerrison rongeur. It is further contemplated that one or more of the materials may be molded from, for example, an inert plastic material. Furthermore, the materials preferably are lightweight such that the collector is readily manipulated by hand. Furthermore, the collector may be disposable, in that the collector may be used during a single medical procedure for a patient and then discarded. Alternatively, one or more components of the collector (including all of the components) are designed to and are able to be sterilized for reuse with another patient during another procedure. 
     A Sixth Embodiment 
       FIG.  7   a    is a perspective view of a collector  600  used to collect cut bone from a kerrison rongeur in accordance with another embodiment of the present invention, wherein the collector  600  is illustrated in a generally horizontal orientation. Each of  FIGS.  7   b   7   c    is a respective side elevational view of the collector  600 . The collector  600  is similar in construction and use as the collector  500  discussed above with reference to  FIGS.  6   a  and  6   b   . A primary difference over the collector  500 , however, is that the wall  521  is replaced with a depressible button  621 . The button  621  preferably is spring-loaded and biased into an extended position, shown in  FIG.  7   a    in solid line and additionally shown in  FIG.  7   b   , in which extended position passage through the cap  605  to an interior containment space of the container body  601  is not blocked. Upon being fully depressed, the button extends into and blocks passage through the cap  605 , as shown in phantom in  FIG.  7   a   . When in the depressed position, the button serves as a stop in same manner as wall  519  in collector  500 , described above. 
     A Seventh Embodiment 
       FIG.  8   a    is a perspective view of a collector  700  used to collect cut bone from a kerrison rongeur for harvesting in accordance with another embodiment of the present invention, wherein the collector  700  is illustrated in a generally horizontal orientation. The collector  700  is similar in construction and use as the collector  600  discussed above with reference to  FIG.  7   a   ,  FIG.  7   b   , and  FIG.  7   c   . A primary difference over the collector  600 , however, is that the cap includes a ramp  704  that assists in guiding the tip of the end portion of a kerrison rongeur into proper position within the cap. The height of the passage is also less than that of the height of the passage through cap  605 , and the length of travel when depressing the button is consequently less as well. 
     An Eighth Embodiment 
       FIG.  9   a    is a perspective view of a collector  800  used to collect cut bone from a kerrison rongeur for harvesting in accordance with another embodiment of the present invention, wherein the collector  800  is illustrated in a generally horizontal orientation.  FIG.  9   b    is a perspective view of part of a release mechanism  840  of the collector  800 , and  FIG.  9   c    is a schematic illustration representing the arrangement and operation of the release mechanism  840  relative to the scrapers  821  and cap  805  of the collector  800 . 
     The collector  800  includes a release mechanism  840  having a button  823  connected by an arm  842  to a wall  843 . The wall  843  defines a release opening  844  therein. The release mechanism  840  is contained within the cap  805  and includes a spring  845  that biases the release mechanism  840  into a closed configuration, wherein bone collected within intake port  813  using scrapers  821  is blocked from access to an interior containment space of the container body  801 . When the button  823  is depressed against the biasing of the spring  845  in the direction of arrow A, the wall  843  moves (slides) so as to align the release opening  844  with the intake port opening  813  thereby permitting the collected bone to pass to the interior of the container body  801 . When in the closed configuration, the wall  843  serves as a stop for the distal end of a kerrison rongeur, in which position the scrapers  821  pass through the cutting area when the cap  805  is rotated about its longitudinal axis relative to the kerrison rongeur. 
     Additional Embodiments Utilizing Suction

     A perspective view of two collectors  2600 , 2650  each in accordance with another respective embodiment of the invention are illustrated in  FIGS.  26   a - 24   f   . The two collectors  2600 , 2650  are structurally the same with the exception that brush  2610  of collector  2600  comprises bristles of the same length, whereas brush  2660  of collector  2650  has varying length bristles. In particular,  FIG.  26   a    is a side-by-side elevational view of the tops of the collectors  2600 , 2650  looking through the ports (wide side openings) in the caps thereof at the brushes  2610 , 2660 . where the varying length bristles of brush  2660  can be seen.  FIG.  26   b    is a perspective view of the caps of the collectors  2600 , 2650  after the caps have been unscrewed from the containers and placed upside down on a surface to expose views of the brushes  2610 , 2660 . As perhaps best shown in  FIG.  26   b   , the brushes are secured to a generally semicircular area of the underside of the respective caps. Continuing with reference to collectors  2600 , 2650 ,  FIG.  26   c    is a side-by-side top perspective view of these collectors, and  FIG.  26   d    is a side elevational view of collector  2650  being held with a left hand. The varying length of the bristles of brush  2660  also are seen in  FIG.  26   d    as well. 
       FIG.  27 - 28   b    demonstrate insertion of the tip of a kerrison rongeur through the port and into the interior of the cap of the collector  2600  in engagement with the brush  2610 . Specifically,  FIG.  27    shows movement of the tip in the direction of arrow A so as to extend through the port; and  FIGS.  28   a  and  28   b    each shows the tip being receive within the cap of the collector  2600  in engagement with the brush  2610 . 
     A perspective view of a collector  2900  in accordance with yet another embodiment of the invention is illustrated in  FIG.  29    and comprises a container  2905  and cap  2910 . The cap includes a slidable plunger that is spring-biased into an open position by spring  2942 . A scraper is located on the plunger inside the cap  2910  and, when the plunger is moved (slides) into the closed position by pressing on tab  2940  with a finger or thumb, the scraper (not shown) moves across the cutting area of a rongeur tip that has been inserted through port  2948  so as to dislodge and clear matter carried on the rongeur in the cutting area. 
       FIG.  30 - 34   b    show a prototype collector  3000  as represented by collector  2900  of  FIG.  29   . In particular,  FIG.  30    shows the collector  3000  held in a person’s left hand with thumb on the tab  3040  of the plunger. An alternative method of holding the collector is with the right hand, as demonstrated in  FIGS.  31  and  32   . 
     The plunger is biased by spring  3042  into an open position.  FIG.  34   a    shows the plunger  3050  in an open position. The spring is attached and secured at one end by a pin to the plunger, and at the other end by a pin to the main body of the cap  3010 . In order to adjust the spring force, the pin can be placed in one of a plurality of holes formed in the cap  3010  as perhaps best seen in  FIG.  30    and illustrated in representative collector  2900  of  FIG.  29   . The cap  3010  includes a port  3048  physically configured to receive the tip of a kerrison rongeur there through, as seen in  FIGS.  33   a  and  33   b   . 
     When inserted through the port  3048 , the distal end  3045  of the tip of the rongeur contacts a stop  3030 , which is best seen in  FIG.  34   b   . Indeed, in  FIG.  34   b    the tip is shown having been inserted through port  3048  of cap  3010  and into abutment with stop  3030 , whereat movement of the plunger by pressing on tab  3040  will force the scraper (in the form of a brush  3025 ) directly through the cutting area of the tip, thereby dislodging matter in the cutting area. 
     “Bristle Field and Teeth” Preferred Embodiments 
       FIG.  35    is a perspective view of a handheld collector  5000  used to collect cut bone from a kerrison rongeur in accordance with another embodiment of the invention. Similarly,  FIGS.  35 A and  35 B  are perspective shaded views of the collector  5000 , and  FIG.  36    is a side elevational view of the collector  5000 . As seen in these drawings, the collector comprises a cap  5002  and a container  5004 . The cap includes an opening  5006  dimensioned to receive there through a distal end of a kerrison rongeur. The view of  FIG.  36    directly faces such opening  5006 . 
     Preferably, the cap is generally circular at its lower perimeter and the opening  5006  extends along the perimeter an arc having an obtuse angle and, more preferably, the opening  5006  extends along an arc having an angle of between 130 degrees and 140 degrees. As such, the opening is wide. The container of the collector comprises a generally elongate body that is cylindrical in shape, and walls of the body define an interior containment space  5008  of the container into which bone falls when dislodged from the distal end of a received kerrison rongeur. 
     An upper portion of the collector is seen in greater detail in  FIGS.  37  and  38    and corresponding shaded views of  FIGS.  37 A and  38 A . In this respect,  FIGS.  37  and  37 A  show a perspective view of the upper portion of the collector including the cap, and  FIGS.  38  and  38 A  show a side elevational view of the upper portion of the collector including the cap. 
     Additionally,  FIG.  39    illustrates a side cross-sectional view of the upper portion of the collector;  FIG.  40    is a perspective partial view in cross-section of the cap of the upper portion of the collector; and  FIG.  43    illustrates a bottom view of the cap of the upper portion of the collector, of which  FIG.  43 A  is a bottom shaded view thereof and 43B is a bottom view thereof schematically illustrating distinct areas of different pluralities of scrapers. 
     As perhaps best seen in  FIG.  39   , the cap includes a threaded portion 5010 that engages and mates with a threaded portion  5012  of the container when the cap and container are screwed together. The cap is thereby attached to the container in an upper portion of the collector and is removable from the container. 
     In the preferred collector  5000 , the cap includes at least two areas of different pluralities of scrapers for dislodging bone from the distal end of a kerrison rongeur, with a gap extending between the different areas. With particular reference to  FIGS.  39 ,  43 ,  43 A, and  43 B , a first plurality  5014  of similar scrapers  5016  is located in a first area  5018  of the underside of the cap that is in close proximity to the opening, and a second plurality  5020  of similar scrapers  5022  is located in a second area  5024  of the underside of the cap that is further from the opening than the first area  5018 . Moreover, the first and second areas  5018 , 5024  are arranged in spaced relation to each other such that a gap  5026  comprising an absence of scrapers extends between the first plurality  5014  and the second plurality  5020 . 
     Referring now to  FIGS.  39 ,  40 ,  43 ,  43 A, and  43 B , each scraper  5016  is seen to comprise a finger insofar as each scraper comprises a protuberance that is elongate with generally oval cross-section. Moreover, each such finger has a stepped diameter between a proximal portion  5030  thereof and a distal portion  5032  thereof relative to the underside  5031  of the cap ( FIGS.  39  and  40   ). In this respect, such finger includes a larger width at the proximal portion and a smaller width at the distal portion. The width of such finger further tapers along the proximal portion, decreasing as a height-wise extent increases away from the underside of the cap. The width of the distal portion similarly may taper, and in variations between different embodiments of the invention the stepped-diameter may be omitted with the finger tapering along its overall height from the underside of the cap to its distal end. In still other embodiments, it is contemplated that the finger may not taper along its height. In any event, the first area  5018  of the first plurality  5014  of scrapers  5016  itself preferably comprises a grouping of these fingers that collectively form a bristle field, much like that of a brush as seen in  FIGS.  39 ,  40 ,  43 , and  43 A . 
     With continuing reference to  FIGS.  39 ,  40 ,  43 ,  43 A, and  43 B , each scraper  5022  is seen to comprise a wiper having a length and a height that substantially exceeds a width thereof. Moreover, as perhaps best seen in  FIG.  43 B  the second area  5024  of the second plurality  5020  of such scrapers comprises a grouping thereof collectively forming a row of teeth with each tooth being a wiper and with a gap  5028  extending between adjacent teeth. The row of teeth is arranged along an arc generally extending in close relation to a circumferential boundary of the underside of the cap, perhaps as best seen in  FIG.  43   . Additionally, preferably one row of teeth is formed; however, it is contemplated that multiple rows of teeth or different arrangements of the teeth may be utilized within the broader scope of the present invention. 
     In comparison of each scraper  5016  to a scraper  5022 , each scraper  5016  in extending from the underside of the cap is more than twice the height of each scraper  5022 , as perhaps best seen in  FIG.  39   . Indeed, as shown the height of the lower portion of each scraper  5016  is greater than the height of each scraper  5022 . 
     Each scraper is sufficiently rigid so as to generally hold form when not engaged by a distal end of a kerrison rongeur and to generally dislodge bone found in a cutting area of a kerrison rongeur when the scraper is moved into or through the cutting area. Each scraper further is sufficiently flexible and resilient so as to generally deflect and bend—to various extents—upon abutment by and engagement with the distal end of a kerrison rongeur. A scraper may be relatively hard or soft within this range. 
     With respect to the preferred embodiment  5000 , each scraper  5022  is less flexible and resilient when compared to the proximal portion  5030  of each scraper  5016 ; and each scraper  5022  is less flexible and resilient when compared to the distal portion  5032  of each scraper  5016 . Furthermore, the proximal portion  5030  of each scraper  5016  is less flexible and resilient when compared to the distal portion  5032  of each scraper  5016 . These differences in the flexibility and resiliency characteristics preferably arise from the differences in the relative thicknesses of the scraper  5022 , the proximal portion  5030 , and the distal portion  5032 . The differences also may arise from differences in shape of the scraper  5022 , the proximal portion  5030 , and the distal portion  5032 ; from differences in the materials from which the scraper  5022 , the proximal portion  5030 , and the distal portion  5032  are formed; and any combination of such possibilities. 
     In the preferred embodiment, each scraper  5022  and the proximal portion  5030  and the distal portion  5032  of each scraper  5016  are all formed from the same material by molding and, preferably, by injection molding. Preferably, these scrapers are integrally formed as a single component  5042  of the cap  5002 , as perhaps best seen in  FIG.  39   . Additionally,  FIG.  44    is a perspective view of the single component. 
     The first component  5042  extends through a plurality of channels  5044 , which are formed in a second, base component  5046  of the cap, to a top surface of the second component  5046 , whereat the first component  5042  includes a topside portion  5048 . The topside portion preferably is located within a recess  5050  formed in the top surface of the second component  5046  and comprises an ornamentation including branding or a decorative element.  FIG.  41    is a perspective cross-sectional view of the second component  5046  of the cap, and  FIG.  42    is a top view of the second component  5046 . 
     In manufacturing the collector  5000 , the cap  5002  preferably is made by injection molding the first component  5042  onto the second component  5046 . The second component also preferably is first molded. Thus, one or more of these components and even the container itself may be molded from one or more inert plastic materials, for example. Furthermore, the materials preferably are lightweight such that the collector is readily manipulated by hand for dislodging bone from a distal end of a kerrison rongeur that is received therein. Additionally, the collector may be disposable, insofar as the collector may be used during a single medical procedure for a patient and then discarded in accordance with applicable HAZMAT protocols. Alternatively, one or more components of the collector (including all of the components) may be designed to be—and are able to be—sterilized for reuse with another patient during another procedure. 
     Still yet in at least some manufacturing methods, the material from which the first component—and specifically the scrapers thereof—is molded also comprises a bio-absorbable material which, if inserted into the body, is absorbed by the body. 
     By molding—and specifically overmolding—the component including the scrapers on both sides of the base component of the cap as well as through the channels in the base component of the cap, the scrapers are permanently affixed to the base component on the underside of the cap and are not removable from the cap without tearing of the overmolded component. As such, there is no need for assembly of the cap, and it is believed that the risk is reduced that one or more scrapers may become detached during aggressive engagement of the distal end of the rongeur with the scrapers. Such manufacturing method further is believed to protect against other product failures arising from other means of attaching the scrapers within the cap. 
       FIG.  45    is a perspective view of a collector  6000  used to collect cut bone from a kerrison rongeur in accordance with another embodiment of the present invention. The collector  6000  is similar in structure to the collector  5000  and includes a cap  6002  and container  6004 .  FIG.  46    is a perspective view of the cap  6002 ;  FIG.  47    is a top view of the cap;  FIG.  48    is a side perspective view of the cap;  FIG.  49    is a bottom perspective view of the cap;  FIGS.  50  and  51    each is a side elevational view of the cap; and  FIG.  52    is a perspective view of the collector  6000  and portion of a kerrison rongeur including distal tip thereof which has been inserted into and received within the cap  6002 . 
     To demonstrate relative size,  FIG.  53    is a photograph of a representative first component  7042  placed adjacent a penny  7070 ; and  FIG.  54    is a photograph of a representative container  7004  being held by hand with a representative second base component  7046  screwed on the container. 
     Yet another collector in accordance with another embodiment of the present invention is similar in structure to collectors  5000 , 6000  and is disclosed in the computer program listing of the appendix, which is incorporated by reference herein. 
     In view of the foregoing, it will be appreciated that in each of these preferred embodiments represented in  FIGS.  35 - 52   , the cap comprises pluralities of scrapers that differ based on flexibility and resiliency as well as arrangement and spacing between adjacent scrapers. Indeed, as seen herein, preferred embodiments each include a first plurality of scrapers shaped and configured in an arrangement to resemble a bristle field like that of a brush, and a second plurality of scrapers shaped and configured in an arrangement to resemble a row of teeth, with the row of teeth extending along the opening and with the bristle field located distal to the opening and with a gap extending between the row of teeth and the bristle field. 
     From experimentation it has been found that this combination of different plurality of scrapers, i.e., the bristle field and teeth, advantageously removes more bone during use of a collector than the bristle field alone. In particular, it has been found that the method of: inserting the distal end of the rongeur through the opening in the cap, preferably at an angle of 30-40 degrees, and preferably without engaging the teeth; then causing the distal end to engage and be moved and rotated within the bristle field; and, upon withdrawal of the distal end, then engaging the distal end with the teeth, results in a greater amount of bone being dislodged within the container than if the teeth were omitted from the collector. 
     In accordance with preferred embodiments of the present invention, a patient advantageously is afforded his or her own bone for the fusion when a collector is used to harvest bone cut from the patient using a kerrison rongeur. For example, lamina chips are clinically proven to have both osteoinductive and osteoconductive properties conducive for bone fusion. By using a patient’s own bone, there is less chance of rejection, infection, and significant cost by not having to rely on bone substitute.
