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.

- 1) a grip member on a first end thereof, a second end of said tool adapted to engage the slot of said fixation pin, and,
- 2) a sleeve member secured to said second end of said tool, a first end of said sleeve member adapted to fit over the first end of the fixation pin such that said second end of said tool is engagable with said slot of said fixation pin and said first end of said sleeve slideably engages a mid-section of said fixation pin.
A medical combination comprising:
- a) a tool having a grip member on a first end thereof, a second end configured to engage a fastening member which is adapted to be rotated;
- and,
- b) a sleeve member securable to said second end of said tool, a first end of said sleeve member adapted to fit over a second end of said tool such that said second end of said tool is engageable with said fastening member and said first end of said sleeve slideably engages a mid-section of said fastening member.
A medical kit comprising:
- a) at least two fixation pins, a first end of each of said fixation pins adapted for attachment to a tool, and a second end of each of said fixation pins being adapted to be screwed into a bone of a patient;
- b) a tool having a grip member on a first end thereof, a Second end adapted to be engagable with the first end of said fixation pin;
- and,
- c) at least two sleeve members, each of said sleeve members individually securable to the second end of said tool, a first end of said sleeve members adapted to fit over the first end of a selected one of the fixation pins such that said second end of said tool is engageable with said fixation pin and wherein said first end of said sleeve slideably engages a mid-section of said selected one of said fixation pins.
