Abstract
A surgical instrument for acetabular cup implantation includes an acetabular cup, a shell body and a drive shaft. The drive shaft includes a drive rod and a handle bar. The handle bar engages the pivot for angular displacement having forward position and backward position. In the forward position the drive rod rotates the acetabular cup forward, and in the backward position the drive rod shifts backward resulting in the acetabular cup engaged the extension portion. Accordingly, the operator rotates the handle bar to control the acetabular cup inserting into the position of acetabulum. The rotation of the handle bar results in the gripping or releasing of the acetabular cup or insert from the invention. Thus the invention provides a clear and ergonomic instrument for medical personnel concerning the operation of acetabular cup implantation.
