Acetabular template component and method of using same during hip arthrosplasty

摘要

A medical imaging device takes one or more images of the local anatomy of a patient undergoing a surgical procedure. A surface model generator receives the one or more images and generates a 3-D surface model of the patient's anatomy. A fabrication device utilizes the 3-D surface model to fabricate a template custom designed to match the surface of the patient's anatomy. Attached to the template is a directional guide vane. The fabrication device is configured to create a template and directional guide vane such that, when the template is fitted to the patient's anatomy, the directional guide vane points along a predefined orientation relative to the patient's anatomy. A physician uses the directional guide vane as a visual guide or cue for installing an implantable prosthetic component during a surgical procedure.

主权项

1. An apparatus for use during surgery on a pelvis of a patient, the apparatus comprising:
a template having a first surface shaped to mate with an outer surface of an acetabulum of the patient, where the first surface is configured such that the template fits to the acetabulum in a single orientation; and a directional guide vane attached to the template, where the directional guide vane
provides a visual indication of a direction in space relative to the pelvis, when the template is fitted to the acetabulum in the single orientation, andis adjustable relative to the template for altering the direction indicated by the directional guide vane, when the template is fitted to the acetabulum in the single orientation.
