X-ray based cut block positioning jig

Abstract

A cut block positioning jig includes a first alignment member, a second alignment member, and both first and second guide members. The first alignment member is movable towards and away from a patient's bone to which the positioning jig is mounted to arrange the jig at a predetermined position relative to the bone based on X-rays of the patient. The second alignment member is movable towards and away from the bone to arrange the jig at the predetermined position relative to the bone. The first and second guide members are configured to direct cut block support members to the bone to couple a cut block to the bone, thus providing the bone with patient-specific cuts.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 13, 2014, an application number of 201480054252.0, and an invention title of "Cutting Die Positioning Fixture Based on X-ray Photos". technical field [0002] The invention relates to a positioning fixture for a cutting mold used for cutting bones. Background technique [0003] This section provides background information related to the present invention which is not necessarily prior art. [0004] To prepare the bone to receive the implant, the bone is often cut using cutting dies. Die guides or positioning jigs can be used to set the correct position of the cutting die. The cutting die guide can be custom designed to fit a specific patient's bone and set the position of the cutting die based on the patient's specific anatomy. Such custom cutting die guides are often based on timely and expensive imaging modalities such as CT and MRI imaging. For exam...
