Abstract

A tool for inserting or removing an intervertebral implant. The tool includes a first arm having a curved tip adapted for engaging a side wall groove of the intervertebral implant and a second arm pivotably coupled to the first arm. The first arm defines a first concave distal surface extending continuously from the curved tip and the second arm defines a second concave distal surface. The first and second concave distal surfaces define an engagement surface engageable to a substantially complementary convex end wall of the intervertebral implant.

Claims (8)

1. A tool for inserting or removing an intervertebral implant, the tool comprising:

a first arm having a proximal end and a distal end, the distal end of the first arm defining a substantially concavely curved first arm surface;

a second arm having a proximal end and a distal end, the second arm pivotably connected to the first arm for movement between a first position for engaging an intervertebral implant and a second position for releasing the intervertebral implant, the distal end of the second arm extending beyond the distal end of the first arm, the distal end of the second arm defining a substantially concave second arm surface and a substantially convexly rounded tip directly adjacent the second arm surface, the first and second arm surfaces defining a concavely curved engagement surface substantially complementary to a convex profile of an end wall of an intervertebral implant; and

a peg extending outwardly from a central portion of the first arm surface of the distal end of the first arm, the peg substantially coaxial to the first arm, the peg receivable in an opening of the end wall of the intervertebral implant; and

wherein the rounded tip is receivable in a recess of a sidewall of the implant, the rounded tip facing the peg, such that the implant can be non-rotatably clamped between the peg and the rounded tip.

2. The tool of claim 1 , wherein the curved engagement surface is non symmetric.

3. The tool of claim 1 , wherein the first and second arms are biased in the second position.

4. The tool of claim 3 , further comprising a lock to secure the arms in the first position.
