Abstract
Abstract A medical instrument impacting tool that is useful for mating to a medical instrument used during spinal surgery is provided. The impacting tool is effective to apply a force to the medical instrument to efficiently and effectively prepare a bone structure, insert or remove a trial implant, insert or remove an implant, or to remove a medical instrument positioned between adjacent bone structures. In general, the medical instrument impacting tool includes a hollow tube, a handle slidably disposed around the tube, and a mass connected to the handle and slidably disposed within the tube.

Dependent Claim
33 words
The medical instrument impacting tool of claim 2 , further comprising an elongate rod disposed within the bore of the handle and extending from the distal end of the handle to the mass.
Claim 6
Dependent Claim
53 words
The medical instrument impacting tool of claim 4 , further comprising a first end cap disposed on the distal end of the cylindrical member, and a second end cap disposed on the proximal end of the cylindrical member, the second end cap including a bore formed therein for slidably receiving the elongate rod.
Claim 7
Dependent Claim
97 words
The medical instrument impacting tool of claim 5 , wherein the mass is effective to apply a proximally directed force to the cylindrical member and the proximal end cap is effective to receive the proximally directed force from the mass upon movement of the handle from the first position to the second position, and the mass is effective to apply a distally directed force to the cylindrical member and the distal end cap is effective to receive the distally directed force from the mass upon movement of the handle from the second position to the first position.
Claim 8
Dependent Claim
152 words
A tool for impacting a medical instrument used during surgery, comprising: an elongate body having a proximal portion, a distal portion, and an inner lumen formed therein, the distal portion including a connector element adapted to mate with a medical instrument; a grasping element having a bore extending therein from a distal end to a proximal end thereof, the grasping element being slidably disposed around the elongate body and selectively movable between a first position and a second position; and a slidable weight disposed within the inner lumen of the elongate body and effective to apply proximally and distally directed forces to the elongate body, the slidable weight being mated to the grasping element such that proximal movement of the grasping element causes simultaneous movement of the slidable weight in a proximal direction and a distal movement of the grasping element causes simultaneous movement of the slidable weight in a distal direction.
Claim 9
Dependent Claim
152 words
A tool for impacting a medical instrument used during surgery, comprising: an elongate body having a proximal portion, a distal portion, and an inner lumen formed therein, the distal portion including a connector element adapted to mate with a medical instrument; a grasping element having a bore extending therein from a distal end to a proximal end thereof, the grasping element being slidably disposed around the elongate body and selectively movable between a first position and a second position; and a slidable weight disposed within the inner lumen of the elongate body and effective to apply proximally and distally directed forces to the elongate body, the slidable weight being mated to the grasping element such that proximal movement of the grasping element causes simultaneous movement of the slidable weight in a proximal direction and a distal movement of the grasping element causes simultaneous movement of the slidable weight in a distal direction.
