Description

Attorney Docket No 0082459-000021JIG GUIDE FOR SURGICAL DRILLCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This patent application is related to and claims the benefit of priority of U.S. provisional patent application no. 63 / 699,344, filed on September 26, 2024, the entire contents of which is incorporated herein by reference.BACKGROUND

[0002] Some medical operations can require use of drills. For example, in the field of orthopedics, drills can be used to form holes in a bone to facilitate insertion of nails, screws, rods, etc., which can assist with proper alignment and healing of the bone that may have been fractured or have experienced other type of trauma. Drill guides and the drill bits themselves can include features to assist with proper placement and alignment of the drill bit during the drilling operation.SUMMARY

[0003] Embodiments can relate to drill guides and the drill bits that include features to assist with proper placement and alignment of the drill bit during a drilling operation.

[0004] Exemplary embodiments can relate to a jig guide system for use with a surgical drill. The jig guide system can include a drill bit having a shaft portion with stepped profile. The jig system can further conclude one or more adapters configured to be used as guides for proper alignment and placement of the drill bit. The stepped profile of the drill bit can act as a mechanical stop to adjust the length of exposure of the drill bit’s working end. With the stepped profile, a single drill bit can be used with different adapters to facilitate different drilling operation. For instance, the drill bit can be used with a first adapter to perform a drill operation on a talus bone. The first adapter can be removed and replaced with a second adapter to perform a drill operation on a fibula bone. Thus, a single drill bit can be used for both drilling operations. This can also obviate the need for removing and replacing different drill bits from the drill that otherwise would be required. The distal ends of the adapters can include ajig extension. The jig extension can be a formation that can facilitate proper placement and alignment of the adapter (and therefore the drill bit) relative to the bone.Attorney Docket No 0082459-000021

[0005] In use, a user can insert an embodiment of the drill bit into a drill. The shaft portion of the drill bit can be received within a receptacle of a first adapter, whereby the stepped profile of the drill bit can engage with a proximal end of the first adapter to expose a predetermined length of the drill bit’s working end. The first adapter can include a handle to allow a user to grasp and manipulate the first adapter. The drill, drill bit, and first adapter can be used to drill a hole in a bone (e.g., talus bone). The jig extension on the first adapter can be used to assist a user with proper placement and alignment while the hole is drilled. A user can then remove the drill bit from the first adapter and place it in a receptacle of a second adapter. This can be done while the drill bit is still coupled to the drill. The stepped profile of the drill bit can engage with a proximal end of the second adapter to expose a predetermined length of the drill bit’s working end. The second adapter can include a handle to allow a user to grasp and manipulate the second adapter. The drill, drill bit, and second adapter can be used to drill a hole in a bone (e.g., fibula bone). The jig extension on the second adapter can be used to assist a user with proper placement and alignment while the hole is drilled.

[0006] An exemplary embodiment can relate to a jig guide system for a surgical drill. The system can include a drill bit, including a coupling end, a shank, and a working end. The drill bit can have a longitudinal axis extending from the coupling end to the working end. The coupling end can be configured to be received by a connector of a drill. The shank can have an elongate structure with a stepped profile. The working end can have an elongate structure with a machined surface. The system can include an adapter, including a receptacle and a handle. The adapter can be configured to receive the shank in the receptacle, allow the shank to freely rotate while being received in the receptacle, and arrest motion of the drill bit along the longitudinal axis while being received in the receptacle.

[0007] An exemplary embodiment can relate to a jig guide system for an orthopedic surgical drill. The system can include a drill bit, including a coupling end, a shank, and a working end. The drill bit can have a longitudinal axis extending from the coupling end to the working end. The coupling end can be configured to be received by a connector of a drill. The shank can have an elongate structure with a stepped profile. The working end can have an elongate structure with a machined surface. The system can include a talus adapter, the talus adapter including a receptacle and a handle. The talus adapter can be configured to receive the shank in the receptacle, allow the shank to freely rotate while being received in the receptacle, and arrestAttorney Docket No 0082459-000021 motion of the drill bit along the longitudinal axis while being received in the receptacle. The system can include a fibula adapter, the fibula adapter including a receptacle and a handle. The fibula adapter can be configured to receive the shank in the receptacle, allow the shank to freely rotate while being received in the receptacle, and arrest motion of the drill bit along the longitudinal axis while being received in the receptacle.

[0008] An exemplary embodiment can relate to a method for operating a surgical drill. The method can involve positioning a drill bit within a receptacle of an adapter. The method can involve positioning the adapter and the drill bit so that a working end of the drill bit and a distal end of the adapter abut a workpiece. The method can involve advancing the drill bit to cause the drill bit to advance in a direction of the working end until a formation of the drill bit abuts a proximal end of the adapter.

[0020] The following description is of an embodiment(s) presently contemplated for carrying out embodiments disclosed herein. This description is not to be taken in a limiting sense, but is made merely for the purpose of describing the general principles and features of the present disclosure.

[0021] Embodiments can relate to drill adapter(s) 102 and drill bit(s) 104 that include features to assist with proper placement and alignment of a drill bit 104 during a drilling operation. While exemplary embodiments may describe and illustrate a jig guide system 100 for a surgical drill, it is understood that the jig guide system 100 can be utilized for any type of hand-held drill and for drilling operations other than for surgical operations. It is also understood that while exemplary embodiments may describe and illustrate a jig guide system 100 including a single drill bit 104 and two adapters 102, a system 100 can include any number of drill bits 104 and any number of adapters 102. While it is contemplated for components (e.g., drill bit 104, adapter(s) 102, etc.) of the jig guide system 100 to be used as a kit, they need not be.

[0022] Referring to FIGS. 1-2, embodiments can relate to a jig guide system 100. The jig guide system 100 can be for use with a drill 1. It is contemplated for the jig guide system 100 to be used in a drilling operation during a medical procedure (e.g., orthopedic surgery, dental surgery, veterinary surgery, etc.). Thus, it is contemplated for the jig guide system 100 to be used with a surgical drill 1. It is further contemplated for the surgical drill to be a hand-held drill.

[0023] The jig guide system 100 can include one or more drill bits 104. As it is contemplated for the drill 1 to be a surgical drill, it is further contemplated for the drill bit 104 to be a surgical drill bit 104 (e.g., an orthopedic drill bit, a dental drill bit, etc.). The drill bit 104 can be made ofAttorney Docket No 0082459-000021 metal, metal alloy, ceramic, etc. The drill bit 104 can include a coupling end 106, a shank 110, and / or a working end 118. The drill bit 104 can have a longitudinal axis extending from the coupling end 106 to the working end 108. It is contemplated for the drill bit 104 to have a generally cylindrical shape, but it can have other shapes (e.g., square, hexagonal, etc.). The coupling end 106 can be configured to be received by a connector (e.g., a chuck, a quickdisconnect coupler, a pin-detent coupler, etc.) of a drill 1. The coupling end 106 can be keyed or keyless. The shank 110 can have an elongate structure with a stepped profile. The stepped profile can include one or more formations 112. The one or more formations 112 can be configured to generate a rise or a fall in a surface of the shank 110. For instance, the shank 110 can a cylindrical shape with a diameter. A portion of the shank 110 can have first diameter that steps down in radius to a second diameter. As will be explained herein, this step can form annular structure that can be used as a mechanical stop when used in conjunction with an embodiment of the adapter 102. The working end 108 can have an elongate structure with a machined surface 114. The machined surface 114 can be a profile of the working end 118 that facilitates a type of work to be done on a workpiece (e.g., a bone, tooth, etc.). The machined surface 114 can be in the form of a fluted profile, a spade profile, conical profile, etc. These profiles can provide for different types of bits (e.g., a twisted bit, a spur point bit, a bullet pilot bit, a Forstner bit, an auger bit, a step bit, etc.). The jig guide system 100 can include use of one or more drill bits 104. If more than one drill bit 104 is included in a jig guide system 100, any one drill bit 104 can be the same or different from another drill bit 104 - e.g., any one drill bit 104 can have the same or different length, diameter, material composition, machined surface 114, number and arrangement of stepped profile(s), etc. as that of another drill bit 104.

[0024] The jig guide system 100 can include one or more adapters 102. The adapter 102 can be made of metal, metal alloy, ceramic, polymer, etc. The adapter 102 can include a receptacle 116. The receptacle 116 can be configured to receive at least a portion of the shank 110. For instance, the receptacle 116 can be configured as a sheath that at least partially envelopes at least a portion of the shank 110. It is contemplated for the receptacle 116 to have a profile that complements a profile of a portion of the shank 110.

[0025] The adapter 102 can include at least one handle 118. The handle 118 can extend from a surface of the receptacle 116.Attorney Docket No 0082459-000021

[0026] As a non-limiting example, the adapter 102 can include an elongate member that has a tubular shape with an open surface so as to form sheathing member for the shank 110 (or a least a portion of the shank 110). Again, it is contemplated for the shank 110 to have a generally cylindrical shape. Thus, the elongate member can be in the form of a cylindrical tube with a slotted opening 120. The slotted opening 120 can be sized to allow the drill bit 104, and in particular the shank 110, to be inserted therethrough and removed therefrom. In addition, or in the alternative, the slotted opening 120 need not be sized to allow the shank 110 to be inserted therethrough and removed therefrom. Rather, the drill bit 104 can be inserted into the receptacle 116 via a proximal end 122 of the adapter 102 - e.g., the drill bit 104 can be slid into the receptacle 116 by advancing it through the proximal end 122. In either embodiment, the slotted opening 120 can facilitate routing of one or more sutures to assist with a surgical procedure. Thus, the slotted opening 120 can serve as a suture slot (e.g., an aperture configured to facilitate routing of one or more sutures). For instance, with reference to FIG. 7 as an exemplary implementation, the jig guide system 100 can be used to assist with drilling one or more holes in a bone. The jig guide system 100 can then be used to further assist a user with routing one or more sutures through the one or more holes. FIG. 7 shows sutures being routed through holes drilled into the ankle bone. As can be appreciated, the jig guide system 100 can allow a user to route a suture through the slotted opening 120 so as to support the suture when the suture is being manipulated by the user. The jig guide system 100 can also be used apply pressure against the bone and therefore support the bones in a desired position when attempting to manipulate the sutures. The jig extension 130 (discussed later) may also help in this regard. As can be appreciated from FIG. 7, if a suture anchor is passed through the jig guide system 100 via the slotted opening 120 and inserted into bone, the slotted opening 120 can allow suture limbs (with or without needles attached to the ends of the suture limbs) to exit the jig guide system 100 through the slotted opening 120. With continued reference to the exemplary embodiment in FIG. 7, a suture anchor can be passed through the jig guide system 100, wherein suture limbs can be slid out of the slotted opening 120 for ease of removal. If needles are attached to the ends of the suture limbs, the slotted opening 120 would be necessary in this exemplary embodiment to facilitate removal of the sutures from jig guide system 100. It is understood that there can be any number of slotted openings 120, the slotted opening 120 can be any length or width, can be straight, curved, angled, etc.Attorney Docket No 0082459-000021

[0027] The elongate member can have an inner surface 126 and an outer surface 128. The inner surface 126 can have a profile that complements a profile of the shank 110. Thus, with the shank 110 being generally cylindrical and the elongate member being generally a cylindrical tube, the inner surface can have a C-shape profile to facilitate reception of the shank 110 in a complementary fashion. The inner surface 126 and the profile of the inner surface 126 can form the receptacle 116 to receive and retain the drill bit 104 within the adapter 102.

[0028] The elongate member of the adapter 102 can have a proximal end 122 (e.g., an end that is most proximal to a user when in use) and a distal end 124 (e.g., an end that is most distal to the user when in use). As the elongate member can be a tubular structure, each of the proximal end 122 and the distal end 124 can have openings for ingress and egress into the receptacle 116. The drill bit 104 can be inserted into the adapter 102 to be received and retained by the receptacle 116 by sliding the drill bit 104 into the adapter via the proximal end 122. For instance, the drill bit 104 can be advanced towards the adapter 102 and directed towards the proximal end 122 opening so that the working end 108 spearheads the insertion of the drill bit 104 into the adapter 102 through the proximal end 122 opening. The drill bit 104 can be advanced further until the shank 110, or at least a portion of the shank 110, is received and retained by the receptacle 116. The complementary profile of the receptacle 116 with that of the shank 110 allows the shank to freely rotate while being seated in the receptacle 116. As will be explained herein, the stepped profile of the shank 110 can be forced or allowed to abut the proximal end 122 to arrest further motion of the drill bit 104 towards the distal end 124. This arrested movement can provide a means to ensure that a predetermined length of the working end 108 of the drill bit 104 extends from the distal end 124 of the adapter 102. This arrested movement can also ensure that the profile of the receptacle 116 mates with the complementary profile of the shank 110 at the arrested movement.

[0029] The handle 118 can extend from the outer surface 128 of the adapter 102. In the exemplary embodiments shown in the FIGS., the slotted opening 120 in formed on a top portion (e.g., an upper most surface when the adapter 102 is held upright during use) of the adapter 102, and the handle 118 extends from a bottom portion (e.g., a lower most surface when the adapter 102 is held upright during use) of the adapter 102; however, the slotted opening 120 and the handle 118 can be located at different portions of the adapter 102. In addition, while the handleAttorney Docket No 0082459-000021118 is illustrated as planar member extending at an angle from the outer surface 128, it can be any shape and extend at any angle.

[0030] The stepped profde of the shank 110 can include at least one formation 112. Each formation 112 can be defined by an increased and / or decreased radius of the shank 110 so as to generate a step in diameter of the shank 110. This formation (e.g., an annular structure of the shank 110) can be configured to abut the proximal end 122 of the receptacle 116 so as to act as a mechanical stop for arresting motion of the drill bit 104. As will be explained herein, the drill bit can have more than one formation 112. One formation 112 can be the same or different from another formation 112. It is contemplated for the shank 110 to include at least three formations 112. For instance, the stepped profile of the shank 110 can include a first formation 112 defined by radius Ri, a second formation defined by radius R2, and a third formation defined by radius R3. The first adapter (e.g., talus adapter) 102 can have a receptacle 116 that complements a shape of the formation 112 defined by R2. The second adapter (e.g., fibula adapter) 102 can have a receptacle 116 that complements a shape of the formation 112 defined by radius R3. A first formation 112 can be formed at a location on the shank 110 that is more proximal to the coupling end 106 than that of a second formation 112, and the second formation 112 can be formed at a location on the shank 110 that is more proximal to the coupling end 106 than that of the third formation 112. The first formation 112 can have a radius that is greater than a radius of the second formation 112, and the second formation 112 can have a radius that is greater than a radius of the third formation 112 (e.g., the diameter of the annular structure defined by the first formation 112 can be greater than the annular structure defined by the second formation 112, and the diameter of the annular structure defined by the second formation 112 can be greater than the annular structure defined by the third formation 112).

[0031] Referring to FIGS. 3-6, the jig guide system 100 can include plural adapters 102. A first adapter 102 can have a receptacle 116 with a profile that is complementary to a shank 110 portion defined by the second formation 112. The second adapter 102 can have a receptacle 116 with a profile that is complementary to a shank 110 portion defined by the third formation 112. Thus, when the drill bit 104 is inserted into the first adapter 102, the drill bit 104 can be advanced until the first formation 112 abuts the proximal end 122 of the first adapter 102. When the drill bit 104 is inserted into the second adapter 102, the drill bit 104 can be advanced until the second formation 112 abuts the proximal end 122 of the second adapter 102.Attorney Docket No 0082459-000021

[0032] It is contemplated for the jig guide system 100 to include a talus adapter as the first adapter 102, and a fibula adapter as the second adapter 102. The talus adapter 102 can have an elongate member and / or receptacle 116 of length LT. The fibula adapter 102 can have an elongate member and / or receptacle 116 of length LF. LT can be greater than LF. With LT > LF, and the profiles of the talus adapter 102 and fibula adapter 102 being as described above for the first adapter 102 and second adapter 102, respectfully, a drill operation can be performed on a talus bone and a fibula bone using a single drill bit 104.

[0033] It is understood that LT > LF is non-limiting example. It may be desired for LT = LF, LT < LF, etc.

[0034] The first adapter 102 (e.g., talus adapter 102) can have a proximal end 122, a distal end 124, and a longitudinal axis extending from the proximal end 122 to the distal end 124. The distal end 124 can include a jig extension 130. The jig extension 130 can be configured to assist a user with proper placement and alignment while work in done on the workpiece - e.g. while a hole is drilled in the bone). The jig extension 130 of the talus adapter 102 can be a form of a cantilever extending in the longitudinal direction.

[0035] The second adapter 102 (e.g., fibula adapter 102) can have a proximal end 122, a distal end 124, and a longitudinal axis extending from the proximal end 122 to the distal end 124. The distal end 124 can include a jig extension 130. The jig extension 130 can be configured to assist a user with proper placement and alignment while work in done on the workpiece (e.g. hole is drilled in the bone). The jig extension 130 can be in a form of plural toothed formations 112 extending in the longitudinal direction.

[0036] It is understood that the jig extensions 103 for the first adapter 102 and for the second adapter 102 can be of any shape, size, or form. Thus, the jig extension 130 for the first adapter 102 may be in a form of a cantilever, in the form of toothed formations, in the form of a pronged fork, a combination of formations, etc. Similarly, the jig extension 130 for the second adapter 102 may be in a form of a cantilever, in the form of toothed formations, in the form of a pronged fork, a combination of formations, etc.

[0037] Referring to FIG. 8, the jig extension 130 in the form of a cantilever can provide for an offset surface at a specific angle and distance away from the longitudinal axis of the jig guide system 100 to aid in drilling placement and alignment in bone. For example, FIG. 8 shows a talus offset lip that is placed in a specific position on the bone, which can result in a correct drillAttorney Docket No 0082459-000021 and anchor placement. The jig extension 130 in the form of teeth can provide stability on bone during drilling and anchor placement. Any of the adapters 102 can have an offset surface feature, a feature for stabilizing on bone (i.e. teeth, bevel, fish mouth shape), a combination of features, etc.

[0038] An exemplary embodiment can relate to a jig guide system 100 for an orthopedic surgical drill 1. The jig guide system 100 can include a drill bit 104, including a coupling end 106, a shank 110, and a working end 108. The drill bit 104 can have a longitudinal axis extending from the coupling end 106 to the working end 108. The coupling end 106 can be configured to be received by a connector of a drill 1. The shank 110 can have an elongate structure with a stepped profile. The working end 108 can have an elongate structure with a machined surface 114. The jig guide system 100 can include a talus adapter 102. The talus adapter 102 can include a receptacle 116 and a handle 118. The talus adapter 102 can be configured to receive the shank 110 in the receptacle 116, allow the shank 110 to freely rotate while being received in the receptacle 116, and arrest motion of the drill bit along the longitudinal axis while being received in the receptacle 116. The jig guide system 100 can include a fibula adapter 102. The fibula adapter 102 can include a receptacle 116 and a handle 118. The fibula adapter 102 can be configured to receive the shank 110 in the receptacle 116, allow the shank 110 to freely rotate while being received in the receptacle 116, and arrest motion of the drill bit 104 along the longitudinal axis while being received in the receptacle 116. The talus adapter 102 can have a receptacle 116 of length LT. The fibula adapter 102 can have a receptacle 116 of length LF. LT can be greater than LF.

[0039] An exemplary embodiment can relate to a method for operating a surgical drill. The method can involve positioning an embodiment of the drill bit 104 within a receptacle 116 of an adapter 102. The method can involve positioning the adapter 102 and the drill bit 104 so that a working end 108 of the drill bit 104 and a distal end 124 of the adapter 102 abut a workpiece. The method can involve advancing the drill bit 104 to cause the drill bit 104 to advance in a direction of the working end 108 until a formation 112 of the drill bit 104 abuts a proximal end 122 of the adapter 102. The abutment of the formation 112 of the drill bit 104 with the proximal end 122 of the adapter 102 can arrest the advancement of the drill bit 104. The arrested advancement of the drill bit 104 can ensure that the working end 108 of the drill bit 104 is not overextended into the workpiece when drilling is performed. The distal end 124 of the adapterAttorney Docket No 0082459-000021102 can include a jig extension 130 such that placing the jig extension 130 against the workpiece can facilitate control of location and / or motion of the drill bit 104 relative to the workpiece. For instance, when the formation 112 arrests advancement of the drill bit 104, only a certain amount of the working end 118 of the drill bit 104 can extend out from the distal end 124 of the adapter 102. A user can advance the drill bit 104 to engage the mechanical stop and then begin drilling the workpiece until the distal end 124 of the adapter 102 comes into contact with the workpiece, can place a distal end of the working end 118 of the drill bit 104 along with the distal end 124 of the adapter into contact with the workpiece and actuate the drill bit 104 to cause it to advance in the direction of the distal end 124 and into the workpiece until the formation 112 arrests further movement by engaging the proximal end 122 of the adapter 102, or a combination of both.

[0040] Existing drill guides and drill bits do not accommodate use of a single drill bit for multiple applications. Yet, embodiments disclosed herein can provide for a jig guide system 100 with a drill bit 104 having a shank 110 portion with stepped profile. The stepped profile of the drill bit 104 can act as a mechanical stop to adjust the length of exposure of the drill bit’s working end 108. With the stepped profile, a single drill bit 104 can be used with different adapters 102 to facilitate different drilling operation. For instance, the drill bit 104 can be used with a first adapter 102 to perform a drill operation on a talus bone. The first adapter 102 can be removed and replaced with a second adapter 102 to perform a drill operation on a fibula bone. Thus, a single drill bit 104 can be used for both drilling operations. This can also obviate the need for removing and replacing different drill bits from the drill that otherwise would be required.

[0041] It will be apparent to those skilled in the art that numerous modifications and variations of the described examples and embodiments are possible in light of the above teachings of the disclosure. The disclosed examples and embodiments are presented for purposes of illustration only. Other alternate embodiments may include some or all of the features disclosed herein. Therefore, it is the intent to cover all such modifications and alternate embodiments as may come within the true scope of the present disclosure, which is to be given the full breadth thereof. Additionally, the disclosure of a range of values is a disclosure of every numerical value within that range, including the end points.
