Appl. No.:

6/719785

Inventors:

Samuel J. Chiarizzio - Memphis TN
Kenneth W. Russell - Memphis TN

Assignee:

Dow Corning Wright - Arlington TN

International Classification:

A61F 1732
A61F 504
A61F 236

US Classification:

128305

Abstract:

This invention relates to a femoral trial prosthesis/rasp assembly for use in hip implant surgery. The novel handle assembly grips the combination trial prosthesis/rasp in a secure manner by clamping over and locking onto a post on the trial prosthesis/rasp which later serves as a mounting piece for a femoral prosthesis head used in trial reductions. The handle assembly preferably comprises a straight member which has a recess for reception of one half of the post and a pivotable lever which contains an opposing recess which fits over the remainder of the post when a screw is tightened to bring the two recesses together over the post. The trial prosthesis/rasp is cooperatively engaged by a projection located at the end of the handle assembly to hold the trial prosthesis/rasp in a preselected orientation with respect to the handle assembly during use. The trial prosthesis/rasp is easily released from the handle by turning the screw to permit the lower portion of the straight member and lever to separate.
