Abstract
A surgical instrument, and method for use, where the surgical instrument is configured to be inserted into a bone. The surgical instrument can include an elongate arm, a handle having a force application surface, and a working end. The working end can include a first blade, a second blade facing the first blade, and a slot extending longitudinally between the first blade and the second blade.
Claims20
A surgical instrument configured to be inserted into a bone comprising:
- an elongate arm having a proximal end, a central body, and a distal end;
- a handle having a force application surface, the handle coupled to the proximal end of the elongate arm;
- and
- a working end proximate to the distal end of the elongate arm, the working end including:
- a first blade having a first outer surface and an inwardly facing first surface and a second blade having a second outer surface and an inwardly facing second surface;
- wherein the inwardly facing first surface faces the inwardly facing second surface;
- wherein the elongate arm continuously tapers from the central body to a distal end of each of the first blade and the second blade;
- wherein the distal end of each of the first blade and the second blade are configured to be inserted into the bone;
- and
- a slot extending longitudinally between the inwardly facing first surface and the inwardly facing second surface;
- wherein the slot is open at the distal end and terminates in a closed configuration a specified distance removed from the distal end.
A method of inserting a surgical instrument having a proximal end, a central body, a distal end, and a first blade with an inwardly first facing surface extending distally from the central body and a second, opposing blade with an inwardly second facing surface extending distally from the central body, the first blade and second blade configured to be inserted into a bone, the method comprising:
- aligning a distal end of the first blade and a distal end of a second blade on opposing sides of an object implanted into the bone;
- applying a force to the proximal end of the surgical instrument;
- wherein the force is transferred from the proximal end of the surgical instrument to the distal end of the first blade and the distal end of the second blade;
- inserting the distal end of the first blade in concert with the distal end of the second blade into the bone, on opposing sides of the object with at least one application of the force;
- ceasing the application of the force when the first blade and the second blade extend a specified distance into the bone;
- and
- concurrently withdrawing the first blade and the second blade from the bone.
A surgical implant removal system comprising:
- an implant configured to be implanted in a bone;
- wherein the implant is configured to be united with the bone;
- and
- a surgical instrument configured to be inserted into a bone comprising:
- an elongate arm having a proximal end, a central body, and a distal end;
- a handle having a force application surface, the handle coupled to the proximal end of the elongate arm;
- and
- a working end proximate to the distal end of the elongate arm, the working end including:
- a first blade having a first outer surface and an inwardly facing first surface and a second blade having a second outer surface and an inwardly facing second surface;
- wherein the inwardly facing first surface faces the inwardly facing second surface;
- wherein the elongate arm continuously tapers from the central body to a distal end of each of the first blade and the second blade;
- wherein the distal end of each of the first blade and the second blade are configured to be inserted into the bone;
- and
- a slot extending longitudinally between the inwardly facing first surface and the inwardly facing second surface;
- wherein the slot is open at the distal end and terminates in a closed configuration a specified distance removed from the distal end.
