Abstract
A surgical instrument suitable for use in an implant procedure is disclosed. A surgical instrument of the invention can be particularly advantageous for use in grasping, holding and placement of implants in an intervertebral disc space. In a typical embodiment, the surgical instrument has a grasping region to hold the implant, and an impact head for receiving a force in order to insert the implant.
Claims21
A surgical instrument comprising:
- a first and a second arm each having a proximal end and a distal end;
- a connector disposed between the proximal and distal end of each arm about which the first and second arms pivot;
- a grasping surface located at the distal end of the first and the second arm, respectively;
- and
- an impact head attached to the instrument and configured to receive and transmit along a longitudinal axis of the instrument a force to an object releasably held at the grasping surface.

A surgical instrument comprising:
- a first and a second arm each having a proximal end and a distal end, the distal end of the first and the second arm having exterior and interior surfaces, wherein the interior surfaces form a shoulder from a first elevation at the distal end to a second elevation projecting toward a longitudinal axis of the instrument, wherein the interior surfaces are spaced apart and substantially parallel when the instrument is in a fully closed position;
- a connector disposed between the proximal and distal end of each arm about which the first and second arms pivot;
- a locking arrangement configured to lock the arms in a selected position;
- a grasping surface located at the distal end of the first and the second arm, respectively;
- and
- an impact head attached to the instrument and configured to receive and transmit along a longitudinal axis of the instrument a force to an object releasably held at the grasping surface.
