INSTRUMENTO DE CALIBRACION DE ACETABULO |
摘要 |
<p>An acetabulum sizer and drill guide (10) for use in implanting an acetabular cup prosthesis comprises a substantially hemispherical shell (12) having an outside surface (14) that generally conforms to the outside surface of the prosthesis to be fitted into a prepared acetabulum. Viewing ports (18) in the shell (12) enable visual inspection of the acetabulum during sizing thereof. A circular peripheral rim (20) on the shell (12) is generally flush with the peripheral boundary of a properly sized acetabulum when the shell (12) is seated therein. Drill guide structure (24) on the shell (12) functions to guide a drill bit into the pelvis bone adjacent the acetabulum in preparing the acetabulum for the acetabular cup prosthesis. A handle (22) is releasably connected to the drill structure (24) for manipulating the shell (12) during sizing and drilling.</p> |
