Surgical clamp for Lapidus bunion surgery
View Patent ↗Apparatuses, systems, and methods are disclosed for a surgical clamp for Lapidus bunion surgery. A surgical clamp has handles disposed at opposing branches of a surgical clamp. A hinge is disposed at an intersection of the opposing branches about which the opposing branches pivot. A first gripper is disposed at a distal portion of the first opposing branch and is shaped to hook around and grip a neck of a first metatarsal. A second gripper is disposed at a distal portion of the second opposing branch and is shaped to hook around and grip a neck of a different metatarsal. The grippers extend at a non-zero angle away from the opposing branches. A lock extends between the opposing branches and selectively fixes a relative position of the opposing branches so that the grippers selectively hold a position of the first metatarsal relative to the different metatarsal.
1. A surgical clamp for Lapidus bunion surgery, the surgical clamp comprising:
first and second opposing handles disposed at a proximal portion of opposing first and second branches of a surgical clamp;
a hinge disposed at an intersection of the opposing branches about which the opposing branches pivot within a plane in response to actuation of the handles;
a first gripper disposed at a distal portion of the first opposing branch, the first gripper shaped to hook around and grip a neck of a first metatarsal;
a second gripper disposed at a distal portion of the second opposing branch, the second gripper shaped to hook around and grip a neck of a different metatarsal, the first and second grippers extending out of the plane in which the opposing branches pivot at a non-zero angle of at least forty-five degrees away from the opposing branches thereby extending the first and second opposing branches over toes and away from a foot of the first metatarsal and the different metatarsal; and
a lock extending between the opposing branches and selectively fixing a relative position of the opposing branches such that the first and second grippers selectively reduce an intermetatarsal angle of the first metatarsal relative to the different metatarsal and hold a frontal plane rotation of the first metatarsal.
2. The surgical clamp of claim 1 , further comprising one or more holes disposed in at least one of the first and second grippers, the one or more holes shaped and positioned to receive wire.
3. The surgical clamp of claim 2 , further comprising wire feeding hardware coupled to at least one hole of the one or more holes, the wire feeding hardware comprising a tube shaped to receive the wire and configured to one or more of lock the wire, drive the wire through the at least one hole, and retract the wire from the at least one hole.
4. The surgical clamp of claim 2 , wherein the wire passes through the one or more holes and through bone of at least the first metatarsal thereby holding a rotation of the first metatarsal.
5. The surgical clamp of claim 1 , wherein the first and second grippers selectively hold the position of the first metatarsal relative to the different metatarsal in multiple planes.
6. The surgical clamp of claim 5 , wherein the first and second grippers selectively hold the position of the first metatarsal relative to the different metatarsal in at least the frontal and sagittal planes.
7. The surgical clamp of claim 1 , wherein the first and second grippers selectively hold the position of the first metatarsal relative to the different metatarsal and a rotation of the first metatarsal.
8. The surgical clamp of claim 1 , wherein the first and second grippers are shaped to allow dorsiflexion of a phalangeal joint of the first metatarsal while selectively holding the position of the first metatarsal relative to the different metatarsal.
9. The surgical clamp of claim 1 , wherein the first and second grippers comprise serrated spoons shaped to hook around and grip the necks of the first metatarsal and the different metatarsal.
10. The surgical clamp of claim 1 , wherein the non-zero angle at which the first and second grippers extend away from the opposing branches comprises a substantially perpendicular angle.
11. The surgical clamp of claim 1 , wherein the lock comprises a complimentary pair of lugs with pawls cooperating against each other to perform a rack function to selectively fix the relative position of the opposing branches.
12. The surgical clamp of claim 1 , wherein the lock comprises a threaded arm and the relative position is fixed by twisting a complimentary threaded knob around the threaded arm.
13. The surgical clamp of claim 1 , wherein the surgical clamp comprises a polymer material and the surgical clamp is a disposable, one-time-use surgical clamp.
14. The surgical clamp of claim 1 , wherein the second gripper is smaller than the first gripper with a different shape than the first gripper such that the second gripper corresponds specifically to the different metatarsal and the surgical clamp is shaped for use with one of a left foot and a right foot.
15. The surgical clamp of claim 1 , wherein the non-zero angle of the first and second grippers extends the first and second opposing branches over the toes and away from the foot of the first metatarsal and the different metatarsal out of the way of a surgery on the foot.
16. The surgical clamp of claim 1 , wherein the different metatarsal comprises one of a second metatarsal and a third metatarsal.
17. An apparatus comprising:
means for pivoting, within a plane, opposing first and second branches of a surgical clamp about an axis from a proximal end of the opposing first and second branches;
means for hooking around and gripping a neck of a first metatarsal from a distal end of the first branch at a non-zero angle with the first branch of at least seventy degrees out of the plane in which the first and second branches pivot;
means for hooking around and gripping a neck of a different metatarsal from a distal end of the second branch at a non-zero angle with the second branch of at least seventy degrees out of the plane in which the first and second branches pivot; and
means for selectively fixing a relative position of the opposing branches and for selectively holding a position of the first metatarsal relative to the different metatarsal thereby reducing an intermetatarsal angle of the first metatarsal relative to the different metatarsal and holding a frontal plane rotation of the first metatarsal.
18. The apparatus of claim 17 , further comprising means for one or more of locking a wire, driving a wire, and retracting a wire through the first metatarsal.
19. A method comprising:
forming first and second opposing handles at a proximal portion of opposing first and second branches;
disposing a hinge at an intersection of the opposing branches about which the opposing branches pivot within a plane in response to actuation of the handles;
forming a first gripper at a distal portion of the first opposing branch, the first gripper shaped to hook around and grip a neck of a first metatarsal;
forming a second gripper at a distal portion of the second opposing branch, the second gripper shaped to hook around and grip a neck of a different metatarsal, the first and second grippers extending out of the plane in which the opposing branches pivot at a non-zero angle of at least forty-five degrees away from the opposing branches thereby extending the first and second opposing branches over toes and away from a foot of the first metatarsal and the different metatarsal;
forming one or more holes in at least one of the first and second grippers; and
forming a lock extending between the opposing branches to selectively fix a relative position of the opposing branches such that the first and second grippers are configured to selectively hold a position of the first metatarsal relative to the different metatarsal.
20. The method of claim 19 , further comprising:
coupling wire feeding hardware to at least one hole of the one or more holes.
