Title: Splint device for guided surgical robot

Description:
BACKGROUND 
     Field of the Disclosure 
     The present application relates to surgical robots and associated guidance systems and, more particularly, to a splint device for forming a fiducial marker and/or a tracking marker for the guidance system of a surgical robot. 
     Description of Related Art 
     Robotic systems are being increasingly implemented in surgical applications. One such example involves a surgical robot used in dental surgery. Such robots are often associated with a guidance system used to guide the surgical instrument implemented by the surgical robot. The guidance system may also be configured to be involved in the surgical pre-planning process, whether by being involved in gathering and/or analyzing patient data, and planning the surgical procedure, or by relying upon pre-planning data to guide the surgical instrument to conduct the surgical procedure. 
     In particular, surgical procedures, some surgical robotic systems rely upon a fixed reference point associated with the patient&#39;s body for guiding the surgical robot. That is, some such surgical robotic systems define a frame of reference with respect to the patient&#39;s body so as to account or otherwise compensate for movements or motion of the patient during the procedure, whether during pre-planning or during the actual surgical procedure itself. This reference point must also be repeatable such that multiple engagements/disengagements (i.e., periods between pre-planning and the actual surgical procedure) do not change the frame of reference implemented by the surgical robot or the guidance system associated therewith. 
     In particular instances, the reference point (or the connection between the guidance system and the patient to define that reference point) implemented by the guidance system for the surgical robot may be accomplished through, for example, an optical modality, a mechanical modality, an acoustic modality, or other suitable and appropriate tracking/guiding modality, or combination thereof. In some modalities, particularly used in dental surgery applications, one mechanical modality for forming the reference point (i.e., a “fiducial marker”) may be accomplished, for example, by attaching/securing a rigid element to the head/teeth of the patient. Such a rigid element, in some instances, may be referred to as and may comprise a splint (see, e.g., prior art in  FIGS.  1 ,  2 A, and  2 B ). Such a splint may generally include, for instance, a retainer portion that grips one or more of the teeth (i.e., by way of an adhesive substance, such as an acrylic material applied between the retainer portion and the teeth), a mounting portion (i.e., mounting arm) that connects the retainer portion to a separate kinematic mount, and the kinematic mount, itself, which may comprise an attachment point for a tracking portion associated with the guidance system for the surgical robot (i.e., wherein, for instance, reflective markers may be mounted to the attachment point for optical tracking of the fiducial marker, or the attachment point may include a securing site for forming a mechanical connection therewith for mechanical tracking of the fiducial marker, or the attachment point may otherwise be configured to receive an appropriate element associated with any other suitable tracking arrangement for the fiducial marker). 
     In such instances, it may be preferable for the retainer portion to be as rigid as possible (i.e., the structure of the retainer itself, as well as the fixation thereof to the teeth of the patient) throughout the surgical procedure. However, it may also be preferable for the retainer portion to be readily removable when the surgical procedure is complete. In some instances, it may be preferable for the splint to be reproducibly removed and replaced, for example, between the pre-planning procedure (i.e., a CT scan) which may occur on one day (when the splint must be in place so the fiducial marker(s) associated therewith are captured in the scan), and the surgical procedure may occur on another day (wherein the surgical procedure requires the splint to be in place for tracking/guiding the surgical procedure). In other instances, it may be preferable that a single splint configuration be usable or adaptable across a wide population of patients, for example, as a universal fit device. Further, it may be desirable to have a minimum of separate components of the splint, or if separate components are included, that such separate components are integrated into or are firmly and securely affixed as part of the overall splint assembly. 
     Prior art splint devices as shown, for example, in  FIGS.  1 ,  2 A, and  2 B , also require a careful balance of the adhesive material (i.e., dental acrylic) to be applied in order to be effective in rigidly mounting the retainer portion to the teeth of the patient. For instance, if too little of the adhesive material is applied in the retainer portion, the splint device may be too easily separated from the teeth, since the amount of the adhesive material may not be sufficient to bond the retainer portion to the teeth to sufficiently resist the forces applied thereto during the surgical procedure. However, if too much of the adhesive material is applied to the retainer portion, the excess adhesive material may flows into the tooth undercuts (i.e., the portion of the tooth where the tooth narrows toward the gum-line and/or the spaces between teeth), the retainer portion will not be readily removable at the end of the surgical procedure, without, for instance, drilling into the solidified adhesive material to remove the retainer portion from the tooth/teeth. In such instances, the retainer portion will likely not be re-usable for the particular patient, and if further procedures are required, a new retainer portion, including a new mounting portion for the fiducial marker and/or tracking marker, may also be required. 
     As such, there exists a need for a splint device for forming a fiducial marker for the guidance system of a surgical robot used, for example, in dental surgery which addresses these and other limitations of prior art devices.

     DETAILED DESCRIPTION OF THE DISCLOSURE 
     The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all aspects of the disclosure are shown. Indeed, the disclosure may be embodied in many different forms and should not be construed as limited to the aspects set forth herein; rather, these aspects are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout. 
     Particular aspects of the present disclosure, as shown, for example, in  FIGS.  3 A and  3 B  provide a splint device  100  for use with a guidance system of a surgical robot, for instance, in dental surgery. One skilled in the art, however, will appreciate that the concept of the splint device disclosed herein as forming a fiducial marker and/or a tracking marker, or otherwise a frame of reference for a surgical robotic system may find applicability to other surgical processes not involving dental surgery, such as, for example, orthopedic surgery, ENT surgery, and neurosurgery. As such, the aspects of the disclosure presented herein are merely examples of the applicability of the disclosed concepts and are not intended to be limiting in any manner. 
     Such a splint device  100  implemented in conjunction with a guided surgical robot may comprise, for example, an elongate first splint portion  200  having first and second longitudinal ends  200 A,  200 B and defining longitudinally spaced-apart relief holes  300 , and an elongate second splint portion  400  having first and second longitudinal ends  400 A,  400 B and defining longitudinally spaced-apart relief holes  500 , wherein the second splint portion  400  generally co-extends with the first splint portion  200 . A tracking portion  600  is engaged with the first splint portion  200  or the second splint portion  400 , and extends outwardly therefrom. More particularly, in some aspects, the tracking portion  600  extends from the first end  200 A,  400 A or the second end  200 B,  400 B of the first or second splint portion  200 ,  400 . In some instances, the tracking portion  600  has a kinematic mount  700  engaged therewith. A first separability provision  800  (see, e.g.,  FIG.  3 B ) is disposed between the first and second splint portions  200 ,  400 . In some aspects, the first separability provision  800  extends longitudinally from between the respective first ends  200 A,  400 A to between the respective second ends  200 B,  400 B of the first and second splint portions  200 ,  400 . 
     In some instances, a second separability provision  900  (see, e.g.,  FIG.  3 A ) extends between one of the relief holes  300 A or  300 B of the first splint portion  200  and one of the relief holes  500 A or  500 B of the second splint portion  400 , wherein the second separability provision  900  is arranged to be severable so as to facilitate adjustability of a length of the first and second splint portions  200 ,  400  and the first separability provision  800 . The adjustability of the length of the splint device  100  via the second separability provision  900  can facilitate, for example, the implementation of the splint device  100  to a variety of different size applications (e.g., adult teeth or children&#39;s teeth). Moreover, since the splint device  100  is generally applied using an adhesive material (e.g., acrylic), the adherence is a function of surface area adhered with the adhesive material. As such, a shorter splint device will have a lesser adhered surface area than a longer splint device, and will therefore be easier to remove at the end of the procedure than the longer splint device. The second separability provision  900 , in some aspects, comprises a reduced section thickness of the first and second splint portions  200 ,  400  between the one of the relief holes  300  of the first splint portion  200  and the one of the relief holes  500  of the second splint portion  400 . The reduced section thickness of the second severability provision  900  can, but does not necessarily, intersect with the slot  850  of the first severability provision  800 . In other aspects, multiple second severability provisions  900  can be provided along the first and second splint portions  200 ,  400  to provide for multiple adjustability of the length of the splint device  100 . 
     In other instances, a tool calibration provision  1000  (see, e.g.,  FIG.  3 B  or  FIG.  5 A ) is engaged with the first splint portion  200 , the second splint portion  400 , the first separability provision  800 , or the tracking portion  600 , wherein the tool calibration provision  1000  is disposed in a predetermined disposition relative to the kinematic mount  700 . The tool calibration provision  1000  may be configured, for example, as a receptacle or other suitable surface feature for receiving the end effector (e.g., a tip of a drill bit) of a surgical instrument affixed to the surgical robot. The tool calibration provision  1000 , in some instances, is formed integrally with the particular component of the splint device  100  or, in other instances, can be a separate and discrete element (e.g., a durable element such as a metal element, a ceramic element, or other suitable element). Since the tool calibration provision  1000  is in a known disposition relative to the kinematic mount  700 , the tool calibration provision  1000 , upon interaction with the end effector of the surgical robot, provides a confirmation or calibration that the end effector is accurately tracked in relation to the surgical robot for conducting a procedure. In some instances, the tool calibration provision  1000  is radiopaque such that the disposition thereof with respect to the kinematic mount  700  can be determined and/or confirmed through imaging analysis. 
     In yet other instances, a fiducial marker element  1100  (see, e.g.,  FIGS.  5 A and  5 B ) is received by a depression  1200  defined by an outer surface of the first splint portion  200 , the second splint portion  400 , the first separability provision  800 , or the tracking portion  600 , wherein the fiducial marker element  1100  is received in a predetermined disposition relative to the kinematic mount  700 . In particular aspects, the splint device  100  defines a plurality of depressions  1200  arranged to receive a plurality of fiducial marker elements  1100 . For example, in some aspects, the fiducial marker element  1100  is spherical and the depression  1200  is hemispherical or an elongate concave channel arranged to receive the spherical fiducial marker element  1100 . Once secured with the respective depression  1200 , whether through an interference fit (e.g., a press fit), by overmolding, or with an adhesive material (e.g., epoxy) disposed with the depression, the fiducial marker element(s)  1100  are essentially embedded within the splint device  100 . Moreover, in some aspects, the depressions  1200  are oriented such that the adhesive material (e.g., epoxy) is retained, such as by gravity, at the location in the depression  1200  at which the fiducial marker element  1100  is secured/embedded. Since the fiducial marker element(s)  1100  are radiopaque in some aspects, the fiducial marker element(s)  1100  can be detected through imaging analysis (e.g., a CT scan). Accordingly, in particular instances, the fiducial marker element(s)  1100  are radiopaque and can be differentiated from the splint device  100  (e.g., formed of a plastic/polymeric material) and the adhesive material (e.g., acrylic) used for adhering the splint device  100  to the patient. Since the fiducial marker element(s)  1100  are all embedded with the splint device  100 , the field of view of the imaging analysis (e.g., the CT scan) can be reduced. 
     In some aspects, the first and second splint portions  200 ,  400  and the first separability provision  800  are integrally formed as a single assembly. In other aspects, the first and second splint portions  200 ,  400 , the first separability provision  800 , and the tracking portion  600  are integrally formed as a single assembly. In still other aspects, the kinematic mount  700  is integrally formed with the tracking portion  600 . The kinematic mount  700  (see, e.g.,  FIGS.  3 A- 3 B  or  FIGS.  5 A- 5 B ), in some instances, defines a central locating receptacle  725  surrounded by three or more angularly spaced-apart protrusions  750 . Such a kinematic mount  700  is generally configured to receive a complementarily-configured mount (not shown) including or engaged with a tracking provision. The tracking provision can include, for example, a physically connected tracking provision such as a tracking arm connected to the surgical robot. In other instances, the tracking provision can include, for example, a non-physically connected tracking provision such as an optical tracking device, a magnetic tracking device, a wireless or WiFi tracking device, an electromagnetic tracking device, an inductive tracking device, or any other form of tracking device that does not require a physical connection between the tracking provision affixed to the kinematic mount  700  and the surgical robot. In either instance, the integration of the kinematic mount  700  into the tracking portion  600  provides for repeatable engagement with the tracking provision, with interchangeable engagement between different types of tracking provisions. The integration of the kinematic mount  700  can further be accomplished, for example, through molding, machining, and or 3D printing. In yet other aspects, the second separability provision  900 , the tool calibration provision  1000 , and/or the depression(s)  1200  are integral with the overall assembly of the splint device  100 . When formed as an integral assembly, the splint device  100  may be formed, for example, using any suitable formation procedure such as injection molding, casting, or machining, as necessary or appropriate. 
     In some aspects, the first and second splint portions  200 ,  400  and the first separability provision  800  interact to collectively form an elongate channel (see, e.g.,  FIGS.  4 A- 4 B ) having an inner surface  1300  defining a concavity (e.g., a “U” channel), and wherein the first separability provision  800  defines a reduced section thickness  825  between and in relation to the first and second splint portions  200 ,  400 . The first and second splint portions  200 ,  400  cooperate with the reduced section thickness  825  to define a slot  850  in the inner surface  1300 , wherein the slot  850  extends longitudinally between the respective first ends  200 A,  400 A and second ends  200 B,  400 B of the first and second splint portions  200 ,  400 . The slot  850  is arranged to receive a divider  875 , wherein the divider  875  extends along the slot  850 . Accordingly, the divider  875  and the first splint portion  200  cooperate to define a first longitudinally-extending portion  1325  of the elongate channel, and the divider  875  and the second splint portion  400  cooperate to define a second longitudinally-extending portion  1350  of the elongate channel. In such instances, the longitudinally co-extending first and second portions  1325 ,  1350  of the elongate channel are separated by the divider  875  such that, for example, an adhesive material deposited in the first portion  1325  will not interact with or contact an adhesive material deposited in the second portion  1350 . 
     Any excess adhesive material within the first and/or second portions  1325 ,  1350  of the elongate channel are otherwise relieved by flow of the adhesive material out of the elongate channel through the respective relief holes  300 ,  500  toward the outer surface  1400 . In this manner, upon removal of the splint device  100 , the first separability provision  800  can be severed as appropriate (e.g., by a drill, a saw, a cutter, or any other suitable severing device) along the entire length thereof (e.g., from the first ends  200 A,  400  A to the second ends  200 B,  400 B) of the first and second splint portions  200 ,  400 . In some aspects, the divider  875  (see, e.g.,  FIG.  5 B ) can be a different material, different color, etc. from the first and second splint portions  200 ,  400  and the first separability provision  800  so as to provide an indicium of appropriate severing of the first separability provision  800  (i.e., the divider  875  will appear as a different color, different material, etc. when the first separability provision  800  is completely severed so as to allow the splint device  100  to be removed). In addition, since the divider  875  (see, e.g.,  FIG.  4 B ) extends into the elongate channel (i.e., effectively separating the first separability provision  800  from the underlying teeth to which the splint device  100  is applied), the divider  875  may also protect the underlying teeth from damage from the tool used to sever the first separability provision  800  by providing the indicium of suitable severing of the first separability provision  800  before reaching the underlying teeth. Upon the first separability provision  800  being suitably severed, the first and second splint portions  200 ,  400  are then separately removed by applying a removal force in opposite directions to each of the first and second splint portions  200 ,  400 , since there is no or limited interaction between adhesive materials deposited in the first and second portions  1325 ,  1350  of the elongate channel. 
     In some aspects, the first separability provision  800  (see, e.g.,  FIGS.  3 A- 3 B  or  FIGS.  5 A- 5 B ) defines one or more holes and/or slots  1375  each extending from an outer surface  1400  of the elongate channel through the reduced section thickness  825  and to the slot  850 , wherein the one or more holes and/or slots  1375  are spaced apart (longitudinally) along the first separability provision  800  between the respective first ends  200 A,  400 A and second ends  200 B,  400 B of the first and second splint portions  200 ,  400 . In some aspects, the holes/slots  1375  can be supplemented, for example, by one or more depressions or concavities  1380  interspersed between successive holes/slots  1375 , wherein the depressions/concavities  1380  can cooperate with the holes/slots  1375  to serve as guides for a cutting/severing tool. Accordingly, severing the first separability provision  800 , such as by cutting through the reduced section thickness  825  to reach the slot  850 /divider  875 , thus allows the splint device  100  to be removed in separate sections such as by applying forces in opposite directions to the first and second splint portions  200 ,  400 .
