Abstract

The invention discloses a femoral neck measuring method, system and device based on optical localization and a medium, and the method comprises the steps: measuring an affected limb after a femoral stem prosthesis is installed through an optical localization probe, and calculating the actual length of the femoral neck required by the affected limb according to the osteotomy surface of the affected limb determined after the femoral stem prosthesis is installed; determining a selected femur ball prosthesis and a selected femur neck prosthesis according to the calculated actual length of the femur neck and the measured length of the femur neck of the healthy limb before the operation; the length of the affected limb after the femoral ball prosthesis and the femoral neck prosthesis are implanted is measured, and the length difference between the healthy limb and the affected limb is restrained by adjusting the length of the femoral neck of the affected limb. According to the invention, errors caused by surgical operation are measured and calculated by using an optical measurement technology in total hip replacement, so that the actual effect achieved in the surgical execution process can be determined under the condition that the operation is relatively simple, and medical personnel can adjust the selected prosthesis in time according to each stage of the surgery; the operation quality is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a femoral neck measurement method, system, equipment and medium based on optical positioning. Background technique [0002] Due to the decline in bone quality of the elderly, the elderly are a high-risk population for hip joint diseases. With the development of aging society, total hip arthroplasty (THA) is one of the commonly used methods for the treatment of related hip joint diseases. However, the femur used in total hip arthroplasty depends on preoperative planning, and there are few coping strategies for intraoperative adjustment of femoral neck length. [0003] In the prior art, methods for adjusting the length of the femoral neck during total hip arthroplasty include: (1) using a vertical ruler, a vernier caliper, a Kirschner wire, etc. to measure the distance between two reference points to determine the femoral eccentricity, thereby adjusting The length of the femoral ...
