     BACKGROUND OF NON-LIMITING EXEMPLARY EMBODIMENT(S) OF THE PRESENT DISCLOSURE 
     Technical Field 
     These non-limiting exemplary embodiment(s) relates to medical instrument handles and, more particularly, to an ergonomic multi-functional handle used to manipulate a medical instrument such as an electrosurgical, monopolar, laparoscopic instrument, for example, while reducing user fatigue. 
     Prior Art 
     Surgery is a learned skill requiring many years of training to develop an understanding of medical procedures, disease processes and healing that far exceed the basic medical principles. The surgeon must develop hand-to-eye coordination and acquire skills utilizing a variety of highly specialized medical instruments. The medical instruments and tools are an extension of the surgeon&#39;s hand. The surgeon&#39;s ability to perform the medical procedures with instruments and tools designed to benefit skill is paramount to the successful outcome for the patient. To enhance the medical performance to better serve the patient means developing instrument handles which are responsive, sensitive and ergonomically designed to benefit the natural motions of the human hand. 
     For example, laparoscopic instruments have been heavily developed for use by surgeons during medical procedures since around 1980s. There are many advantages of laparoscopic surgery compared with open procedure. These advantages include: reduced hemorrhaging which reduces needing a blood transfusion, smaller incision which reduces pain and shortens the recovery time of the patient, reduced scarring, reduced chances of needing pain medication, reduced hospital stays and quicker return to everyday life, and reduced risk of contamination and infection. Disadvantages of a laparoscopic procedure include: limited range of motion in the medical site, poor depth perception by the surgeon, and often laparoscopic tools are not perceived as moving in the same direction as the surgeon&#39;s hands. 
     In a variety of medical devices used for a diversity of medical or non-medical procedures, devices are designed with a dedicated handle or proximal end and a distal or actuation end. Typically medical device handles prescribe how they will be held in the hand by the layout of their handle shape or position of digit retaining portions. In instruments that contain loops, such as can be found in scissors type devices or grasping type devices, the loops are used for opening and closing the end effector, whether that is a scissors, grasper, clamp or similar device. In medical devices and more specifically minimally invasive or laparoscopic devices, a wide variety of angles of use can be generated. Typically a digit-looped device locks the digits and hand into a single orientation that can only function comfortably across a limited range of angles. Both in angles distal or away from the user and oblique angles or angles acutely to the side of the user, devices with digit loops move beyond their effective comfort range and promote hand stress and fatigue. This stress and discomfort is the result of creating unnatural hand postures. These hand postures can create severe wrist adduction or flexion causing discomfort and a loss of strength or leverage to operate the device. In certain instruments such as instruments used for minimally invasive or laparoscopic dissection, a surgeon may operate a looped device for long periods of time, across a wide range of angles. 
     In other conventional instruments, the handle comprises two holes for insertion of middle digit in one ring and digit in the other ring. The sizes of these rings are often small and not optimized for all types of hand sizes. This method in which the whole instrument is supported by only a thumb and finger and in which case, the hand and wrists make a very awkward and unnatural angle with respect to the angle of use is often very cumbersome to the surgeon and extended use of instrument in this position causes severe fatigue and hand pain. This results in painful situations during extended surgeries. 
     Accordingly, a need remains for an ergonomic medical instrument handle to overcome at least one of the above-noted shortcomings. The non-limiting exemplary embodiment(s) satisfies such a need by providing an ergonomic medical instrument handle that is convenient and easy to use, lightweight yet durable in design, versatile in its applications, and designed for easily and conveniently enabling a user to articulate his/her digit while operating the medical instrument handle and thereby reduce fatigue and discomfort during extended medical procedures. 
     BRIEF SUMMARY OF NON-LIMITING EXEMPLARY EMBODIMENT(S) OF THE PRESENT DISCLOSURE 
     In view of the foregoing background, it is therefore an object of the non-limiting exemplary embodiment(s) to provide an ergonomic multi-functional handle used to manipulate a medical instrument such as an electrosurgical, monopolar, laparoscopic instrument, for example, while reducing user fatigue. These and other objects, features, and advantages of the non-limiting exemplary embodiment(s) are provided by a multi-functional handle for manipulating a medical instrument. Such a multi-functional handle includes a body capable of being gripped by a hand of a user and capable of being in communication with a medical instrument. Such a body includes a first portion and a second portion coupled thereto such that the second portion is displaced relative to the first portion. In this manner, one of the first portion and the second portion is capable of manipulating the medical instrument. 
     In a non-limiting exemplary embodiment, the multi-functional handle further includes a first trigger assembly. Such a first trigger assembly preferably includes an actuation arm, and a primary digit-receiving member coupled to the actuation arm. The first trigger assembly is pivotally coupled to the body in such a manner that the actuation arm is capable of actuating the medical instrument independently from movement of the primary digit-receiving member. In this manner, the primary digit-receiving member is selectively displaced between alternate orientations relative to a position of the body and relative to a position of the actuation arm, respectively. 
     In a non-limiting exemplary embodiment, when each of the first portion, second portion and first trigger assembly are present, both the first trigger assembly as well as one of the first portion and second portion operates the medical instrument. 
     In a non-limiting exemplary embodiment, when each of the first portion, second portion and first trigger assembly are present, either the first trigger assembly operates the medical instrument or one of the first portion and second portion operates the medical instrument. 
     In a non-limiting exemplary embodiment, the primary digit-receiving member is selectively displaced between alternate orientations relative to a position of the body and relative to a position of the actuation arm, respectively. 
     In a non-limiting exemplary embodiment, the primary digit-receiving member is linearly reciprocated along a linear travel path extending outwardly from a proximal end of the actuation arm. 
     In a non-limiting exemplary embodiment, the primary digit-receiving member is freely articulated about an x-axis, y-axis and z-axis. 
     In a non-limiting exemplary embodiment, the multi-functional handle further includes a secondary digit-receiving member attached to the body. 
     In a non-limiting exemplary embodiment, the secondary digit-receiving member is fixedly coupled to the body. 
     In a non-limiting exemplary embodiment, the multi-functional handle further includes a tertiary digit-supporting member attached to the body. 
     In a non-limiting exemplary embodiment, the tertiary digit-supporting member is fixedly coupled to the body. 
     In a non-limiting exemplary embodiment, the tertiary digit-supporting member is pivotally coupled to the body. 
     In a non-limiting exemplary embodiment, the tertiary digit-supporting member is pivotally coupled to the second portion and extends proximally away therefrom. 
     In a non-limiting exemplary embodiment, the tertiary digit-supporting member is resiliently coupled to the second portion thereby returning to an equilibrium position after being biased to an offset position. 
     The present disclosure further includes a method of utilizing a multi-functional handle for manipulating a medical instrument. Such a method includes the steps of: obtaining and gripping a body in a hand of a user wherein the body includes a first portion and a second portion coupled thereto; and displacing the second portion relative to the first portion such that one of the first portion and the second portion manipulates a medical instrument. 
     There has thus been outlined, rather broadly, the more important features of non-limiting exemplary embodiment(s) of the present disclosure so that the following detailed description may be better understood, and that the present contribution to the relevant art(s) may be better appreciated. There are additional features of the non-limiting exemplary embodiment(s) of the present disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.

     The non-limiting exemplary embodiment(s) is/are referred to generally in  FIGS. 1-28A  and are intended to provide an ergonomic multi-functional handle  100  used to manipulate a medical instrument  180  such as an electrosurgical, monopolar, laparoscopic instrument, for example, while reducing user fatigue. It should be understood that such non-limiting exemplary embodiment(s) may be used to manipulate many different types of medical instruments  180 , and should not be limited to the uses described herein. 
     Referring initially to  FIG. 1 , in accordance with the non-limiting exemplary embodiment(s), a perspective view showing a multi-functional handle  100  for use with a medical instrument  180  is disclosed. Such a handle  100  includes a body  150  having a plurality of digit-receiving members (primary digit-receiving member  131 , secondary digit-receiving members  155 ,  156  and tertiary digit-supporting member  157 ) and a first trigger assembly  120  operatively coupled to second trigger assembly  130 . A third trigger assembly  140  locks the primary digit-receiving member  131  at a desired position relative to the body  150 . 
     The term digit, as used in the present disclosure, is intended to mean any portion(s) of a user&#39;s hand, thumb, metacarpals, phalanges, fingers, etc. The terms “first position” and “second position” mean both up and down positions relative to each other for permitting and prohibiting movement of the first trigger assembly  120 . For example, the “first position” can be either the up position or down position. The “second position” can be either the up position or down position, so long as it is not the same as the “first position.” 
     In preferred embodiments, as shown in  FIGS. 1-26A , the ergonomic multi-functional handle  100  may be operated with a second trigger assembly  130  (described herein below). 
     In a preferred embodiment, as shown in  FIGS. 27-28A , the ergonomic multi-functional handle  100  may be operated without the second trigger assembly  130  (described herein below). 
       FIGS. 1-28A  illustrate various embodiments of a multi-functional handle  100  for manipulating a medical instrument  180 . Such a multi-functional handle  100  includes a body  150  capable of being gripped by a hand of a user and further capable of being in communication with a medical instrument  180  via a distal end  101  equipped with a rotation knob  102  as well as a first trigger assembly  120  (described in more detail herein below). The secondary digit-receiving members  155 ,  156  may include a curvilinear distal outer surface  108  having a concave radius of curvature suitable sized and shaped to receive a user digit thereagainst. Curvilinear surfaces  109 ,  110  may be ribbed or otherwise corrugated to receive one or more user digits. Such surfaces  108 ,  109 ,  110  may be portions of complete loops and/or incomplete loops. Body  150  includes a first portion  151  and a second portion  152  coupled thereto such that the second portion  152  is displaced relative to the first portion  151 . In this manner, one of the first portion  151  and the second portion  152  is capable of manipulating the medical instrument  180 . The terms “first portion”  151  and “second portion”  152  may include upper and lower portions of the body  150 , which may include one or more of the primary digit-receiving member  131 , secondary digit-receiving member  155 ,  156 , and tertiary digit-supporting member  157 . Also, the “first portion”  151  and/or the “second portion”  152  may be formed from deformably resilient material and/or rigid plastic. 
     In a non-limiting exemplary embodiment, as shown  FIGS. 1-26A , the multi-functional handle  100  further includes a first trigger assembly  120 . Such a first trigger assembly  120  preferably includes an actuation arm  129 , and the primary digit-receiving member  131  coupled to the actuation arm  129 . The first trigger assembly  120  is pivotally coupled to the body  150  in such a manner that the actuation arm  129  is capable of actuating the medical instrument  180  independently from movement of the primary digit-receiving member  131 . In this manner, the primary digit-receiving member  131  is selectively displaced between alternate orientations relative to a position of the body  150  and relative to a position of the actuation arm  129 , respectively. 
     In a non-limiting exemplary embodiment, when each of the first portion  151 , second portion  152  and first trigger assembly  120  are present, both the first trigger assembly  120  as well as one of the first portion  151  and second portion  152  operates the medical instrument  180 . 
     In a non-limiting exemplary embodiment, when each of the first portion  151 , second portion  152  and first trigger assembly  120  are present, either the first trigger assembly  120  or at least one of the first portion  151  and second portion  152  operates the medical instrument  180 . 
     In a non-limiting exemplary embodiment, the primary digit-receiving member  131  is selectively displaced between alternate orientations relative to a position of the body  150  and relative to a position of the actuation arm  129 , respectively. 
     In a non-limiting exemplary embodiment, the primary digit-receiving member  131  is linearly reciprocated along a linear travel path extending outwardly from a proximal end of the actuation arm  129 . 
     In a non-limiting exemplary embodiment, the primary digit-receiving member  131  is freely articulated about an x-axis, y-axis and z-axis. 
     In a non-limiting exemplary embodiment, the multi-functional handle  100  further includes at least one secondary digit-receiving member  155 ,  156  attached to the body  150 . 
     In a non-limiting exemplary embodiment, the secondary digit-receiving member  155 ,  156  is fixedly coupled to the body  150 . 
     In a non-limiting exemplary embodiment, the multi-functional handle  100  further includes a tertiary digit-supporting member  157  attached to the body  150 . 
     In a non-limiting exemplary embodiment, the tertiary digit-supporting member  157  is fixedly coupled to the body  150 . 
     In a non-limiting exemplary embodiment, the tertiary digit-supporting member  157  is pivotally coupled to the body  150 . 
     In a non-limiting exemplary embodiment, the tertiary digit-supporting member  157  is pivotally coupled to the second portion  152  and extends proximally away therefrom. 
     In a non-limiting exemplary embodiment, the tertiary digit-supporting member  157  is resiliently coupled to the second portion  152  thereby returning to an equilibrium position after being biased to an offset position. 
     The present disclosure further includes a method of utilizing a multi-functional handle  100  for manipulating a medical instrument  180 . Such a method includes the steps of: obtaining and gripping a body  150  in a hand of a user wherein the body  150  includes a first portion  151  and a second portion  152  coupled thereto; and displacing the second portion  152  relative to the first portion  151  such that one of the first portion  151  and the second portion  152  manipulates a medical instrument  180 . 
     In a non-limiting exemplary embodiment, as perhaps best shown in  FIGS. 1 and 14 , the first trigger assembly  120  is operatively coupled to the medical instrument  180  (e.g., laparoscopic tool  180 ). The medical instrument  180  includes a rectilinear drive rod  113  having a proximal end operatively coupled to the handle  100 , as will be explained in more detail hereinbelow. A distal end of the drive rod  113  contains a linkage assembly  111  operatively coupled to a conventional jaw assembly  104 . One skilled in the art understands the conventional operation of such components. The linkage assembly  111  includes a first link lever  163  and a second link lever  169  pivotally coupled to opposite sides of the distal end of the drive rod  113 . Manipulation of the drive rod  113 —via first trigger assembly  120 —causes articulated of the first and second link levers  163 ,  169  about a common fulcrum axis  162  at the distal end of the drive rod  113 . Such first and second link levers  163 ,  169  are also pivotally coupled to first jaw  166  and second jaw  167 , at joints  164 ,  168 , respectively. First and second jaws  166 ,  167  are pivotally coupled to each other via a jaw pin  165 . In this manner, when the distal end of the drive rod  113  is linearly urged—along distance  161 —towards the first and second jaws  166 ,  167 , the first and second link levers  163 ,  169  are caused to pivot along first rotational directions, away from a longitudinal axis  190  of the drive rod  113 . Such pivotal movement urges apart the first and second jaws  166 ,  167  to an open position. Retraction of the drive rod  113 —along distance  161 —away from the jaw pin  165  causes the first and second link levers  163 ,  169  to articulate towards the longitudinal axis  190  of the drive rod  113  and thereby articulate the first and second jaws  166 ,  167  towards a closed position. 
     Referring to  FIG. 2 , in a non-limiting exemplary embodiment, a partially exposed side elevational view illustrating the interrelationship between the internal components of the multi-functional handle  100  shown in  FIG. 1 , is disclosed. The first trigger assembly  120  operates the medical instrument  180  wherein the rectilinear drive rod  113  is housed within the shaft  103 . A proximal end of the drive rod  113  is attached to a distal end of the actuation arm  129 . Such a drive rod  113  may be connected to the actuation arm  129  via a ball/socket joint  128 ,  142  or other fastener suitable for reciprocating the drive rod  113  along a linear travel path  161  defined parallel to the longitudinal axis  190  of the shaft  103  (as perhaps best shown in  FIG. 14 ).  FIGS. 6 and 8  illustrate the drive rod ball joint  128  and actuation arm  129  ball socket  142 . Articulation of the first trigger assembly  120  is effectuated by manual manipulation of the actuation arm  129  along the arcuate path illustrated by the arrow  112 . Connection between the actuation arm  129  and drive rod  113  is spaced from the first pivot axis  126  about which the first trigger assembly  120  pivots. A rotation knob joint  105  is attached to the drive rod  113  at a distal location of the body  150  so that the medical instrument  180  can be selectively articulated via rotation of the actuation arm  129  at a proximal end of the body  150 . Of course, alternately, the position of the actuation arm  129  may be located at a distal end of body  150 . 
     Referring to  FIG. 2 , in a non-limiting exemplary embodiment, an electrical current may be supplied to the medical instrument  180  via a high-frequency (HF) connector plug  107  extending outwardly and away from a top of the body  150 . A HF connector lead  106  is communicatively coupled to the connector plug  107  and travels downward into a hollow cavity of the body  150  wherein it maintains electrical communication with the drive rod  113 . 
     In a non-limiting exemplary embodiment, an energy source such as a tissue-altering energy source may be communicatively coupled to the handle  100 . Exemplary tissue-altering energy sources may generate a heat signal, acoustic signal, microwave signal, light signal, etc., as well-understood by one of ordinary skill in the art. Each tissue-altering energy source may include different components for interfacing with the body  150  and/or the medical instrument  180 . Thus, the HF connector plug  107  and lead  106  are not a necessity and are merely provided as an illustrative example; not restrictive. 
     Referring to  FIG. 3 , in a non-limiting exemplary embodiment, an enlarged view of the second trigger assembly  130 , taken in  FIG. 2 , is disclosed. As noted above, the second trigger assembly  130  permits selective articulation of a portion—actuation arm  129 —of the first trigger assembly  120  along the arcuate path  112  for manipulating the medical instrument  180  (e.g., jaws). Of course, one skilled in the art understands a variety of medical instruments  180  may be manipulated by movement of the first trigger assembly  120 . 
     In a non-limiting exemplary embodiment, the second trigger assembly  130  is employed to selectively lock the actuation arm  129  at alternate positions, as desired. Thus, while the first trigger assembly  120  permits operation of the medical instrument  180 , the second trigger assembly  130  enables the user to lock the first trigger assembly  120  at a desired position thereby preventing further manipulation of the medical instrument  180 . 
     In a non-limiting exemplary embodiment, as perhaps best shown in  FIGS. 3, 4 and 7 , the second trigger assembly  130  preferably includes a ratchet cam shaft  119  formed at the second pivot axis  127 . A ratchet trigger  153  is statically coupled to the ratchet cam shaft  119  and is disposed exterior of the body  150 . The ratchet trigger  153  pivots about the second pivot axis  127  thereby causing a ratchet cam shaft arm  116  to articulate in a corresponding direction. For example, when the ratchet trigger  153  is rotated clockwise, the ratchet cam shaft arm  116  also rotates clockwise; and visa-versa. 
     In a non-limiting exemplary embodiment, a ratchet cam shaft snap fit  117  is formed at an end of the ratchet cam shaft arm  116  and locks to a snap fit anchor bracket  117  statically housed within the body  150 . For example, the snap fit anchor bracket  117  may be friction locked, magnetically locked, or locked via other suitably ways, without departing from the true spirit and scope of the present disclosure. A ratchet pawl cam  121  is statically mated to the ratchet cam shaft  119  and remains angled away from the ratchet cam shaft arm  116  such that it selectively displaces one end of a ratchet pawl  122 . The ratchet pawl  122  has an opposite end anchored to a ratchet pawl attachment boss  123  located distally of the first pivot axis  126 . In this manner, articulation of ratchet trigger  153  along a first rotational direction causes ratchet pawl cam  121  to urge ratchet pawl  122  towards a ratchet arm  147  having a serrated surface. A proximal end of the ratchet pawl  122  engages the ratchet arm  147  teeth  118  and the ratchet cam shaft snap fit  117  locks the ratchet trigger  153  at a locked position. Such cooperation between the ratchet pawl  122 , ratchet arm  147  and ratchet cam snap fit  117  prohibit premature or undesirable movement of the ratchet trigger  153 , thereby maintaining the medical instrument  180  at a desired orientation. 
     In a non-limiting exemplary embodiment, rotation of ratchet trigger  153  in an opposite direction releases the ratchet cam snap fit  117  and disengages the ratchet pawl  122  from the ratchet arm  147 . Such disengagement permits the ratchet arm  147  to articulate in sync with the actuation arm  129  of the first trigger assembly  120  thereby permitting manipulation of the medical instrument  180  as desired. 
     In a non-limiting exemplary embodiment,  FIG. 4  illustrates an enlarged side elevational view of the multi-functional handle  100  for articulation of the first trigger assembly  120  about the first pivot axis  126 . During manipulation of the medical instrument  180 , the first trigger assembly  120  articulates about the first pivot axis  126  and along a first arcuate path  112  while the ratchet trigger  153  is at a lowered position (e.g., unlocked position). To prohibit manipulation of the medical instrument  180 , the ratchet trigger  153  articulates along a second arcuate travel path  124 , and about a second pivot axis  127  offset from the first pivot axis  126 . When the ratchet trigger  153  is articulated to a raised position (e.g., locked position), the actuation arm  129  is prohibited from rotating along the arcuate path  112 . As noted herein above, raised/lowered positions maybe first/second positions and visa-versa. 
     In a non-limiting exemplary embodiment,  FIGS. 5 and 6  are cross-sectional views showing the interrelationship between the first trigger assembly  120 , second trigger assembly  130  and third trigger assembly  140 .  FIG. 8  is an enlarged perspective view illustrating the interrelationship between the third trigger assembly  140  and the actuation arm  129 .  FIG. 9  is an enlarged perspective view illustrating the receiving aperture  146  of the primary digit-receiving member  131 . With reference to  FIGS. 5-6 and 8-9 , the digit locking switch is referred to as the third trigger assembly  140 . Such a mechanism permits selective movement of the primary digit-receiving member  131 , which may be a loop, for example. Of course, the primary digit-receiving member  131  may be a variety of shapes and should not be construed as limited to only a loop shape. 
     In a non-limiting exemplary embodiment, the third trigger assembly  140  is operably coupled to the actuation arm  129  and primary digit-receiving member  131  of the first trigger assembly  120 . The third trigger assembly  140  includes a switch  149  that is linearly reciprocated along a slot  145  formed in the actuation arm  129 . The switch  149  is partially inserted into the actuation arm  129  and has a switch follower  133  statically mated thereto. A switch snap fit arm  134  extends downwardly and distally from the switch follower  133 , traveling along a path  141  aligned substantially parallel to the reciprocating motion of the switch  149  above. A switch snap fit  135  is formed at a distal end of switch arm  134 . Grooves  137 ,  138  are formed within an interior wall of the actuation arm  129 . Such grooves  137 ,  138  are aligned substantially parallel to the linear path  141  wherein, when the switch snap fit  135  is positioned in a proximal groove  137 , the switch arm  134  is locked and prohibited from movement. When the switch snap fit  135  is slidably inserted in the distal groove  138 , a locking shaft  132  is displaced outwardly from a receiving aperture  146  thereby permitting movement of the primary digit-receiving member  131 . Although, the locking shaft  132  has a hexagonal shape with a corresponding hexagonally shaped receiving aperture  146 , any number of interlocking shapes may be used to prohibit movement of primary digit-receiving member  131 . The primary digit-receiving member  131  is coupled to the actuation arm  129  via a joint for maintaining the receiving aperture  146  within the actuation arm  129  during movement of the primary digit-receiving member  131 ; prevents primary digit-receiving member  131  from disengaging the locking shaft  132 . 
     In a non-limiting exemplary embodiment, with reference to  FIGS. 4 and 7 , an enlarged perspective view illustrating articulation of the ratchet arm  153  about the second pivot axis  127  is disclosed. Also, a reference line  191  is shown passing through the secondary digit-receiving members  155 ,  156  located along a medial portion of the body  150 . Such illustration in  FIG. 7  shows an optional movement of the medical instrument  180  along approximately a 100 degree arcuate path. See also  FIGS. 21 and 21A  for further illustration of the medical instrument  180  movement relative to the medial portion of the body  150 .

Of course, the upper portion  1451  may move relative to a stationary lower portion  1452  as well. 
       FIG. 26  is a perspective view illustrating a non-limiting exemplary embodiment of handle  1500  including a bifurcated body  1550  having a lower portion  1552  adjustably coupled to an upper portion  1551  thereof.  FIG. 26A  is a perspective view illustrating the lower portion  1552  of  FIG. 26  linearly displaced relative to the upper portion  1551 . In such an embodiment, the bifurcated region is located intermediately of the secondary digit-receiving members  1555 ,  1556  and the tertiary digit-supporting member  1557 . The connection between the upper portion  1551  and lower portion  1552  of the body  1550  may be friction fitted, such as a snap-fit arrangement or via a detent, for example. A linearly resilient coupling may also be employed for causing the lower portion  1552  to automatically return to an equilibrium position from a tensioned position. Additionally a worm gear or other suitable mechanical and/or electromechanical mechanism may be employed. It is noted that the lower portion  1552  of the body  1550  can be articulated about x, y and z axes (e.g., ball/socket joint). Of course, the upper portion  1551  may move relative to a stationary lower portion  1552  as well. 
     Referring to  FIGS. 27-28A , a non-limiting exemplary embodiment of the handle  1600  is illustrated wherein at least a portion of the second trigger assembly is removed from the body  1650  and non-operable such that the actuation arm  1629  freely articulates along an arcuate path  1612  without selectively locking at alternate positions. 
     While non-limiting exemplary embodiment(s) has/have been described with respect to certain specific embodiment(s), it will be appreciated that many modifications and changes may be made by those of ordinary skill in the relevant art(s) without departing from the true spirit and scope of the present disclosure. It is intended, therefore, by the appended claims to cover all such modifications and changes that fall within the true spirit and scope of the present disclosure. In particular, with respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the non-limiting exemplary embodiment(s) may include variations in size, materials, shape, form, function and manner of operation. 
     The Abstract of the Disclosure is provided to comply with 37 C.F.R. §1.72(b) and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the above Detailed Description, various features may have been grouped together or described in a single embodiment for the purpose of streamlining the disclosure. This disclosure is not to be interpreted as reflecting an intention that the claimed embodiment(s) require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter may be directed to less than all of the features of any of the disclosed non-limiting exemplary embodiment(s). Thus, the following claims are incorporated into the Detailed Description, with each claim standing on its own as defining separately claimed subject matter. 
     The above disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiment(s) which fall within the true spirit and scope of the present disclosure. Thus, to the maximum extent allowed by law, the scope of the present disclosure is to be determined by the broadest permissible interpretation of the following claims and their equivalents, and shall not be restricted or limited by the above detailed description.
