ABSTRACT:
An improved wrench for use in a surgical setting in which a surgical fastener, such as a pin, is supported at a mid-section as well as its base end. The invention uses a tool which has a handle and a mating portion for the surgical pin. This mating portion may be a pong to engage a slot at the pin's base, a hexagonal head to surround the pin's hexagonal shaped base, a semi-circle, or many other such mechanisms well known to those in the art. A sleeve member extends from around the mating portion to extend to a mid-section of the surgical pin to provide sliding support for the surgical pin.
