Methods, systems, and instruments for inserting prosthetic implants

Abstract

An inserter includes a frame having a central bore through which a threaded rod is inserted, the threaded rod being used to secure the inserter to an object such as an implant. A thumbscrew is used to thread the rod into the object. A biasing member is located between the thumbscrew and a slider. A lever on the inserter is provided such that when the lever is closed, the slider is forced toward the thumbscrew, compressing the biasing member and generate opposing forces applied to the thumbscrew and slider. These opposing forces are transferred to the rod and frame and produce a resultant force that causes a compressive force to be exerted between the inserter and object. This resultant force firmly seats the inserter on the object and reduces the possibility that any blows applied to the inserter are diverted to the rod causing the rod to loosen or disengage.

Dependencies are inferred from the claim text.
