Real-time visualization assistant positioning system for interior of hip joint in total hip replacement arthroplasty

Abstract

A real-time visualization assistant positioning system for the interior of a hip joint in total hip replacement arthroplasty is divided into two portions of hardware and software, wherein the hardware can be divided into three modules of a sensing data gathering module, a data merging and processing module and a data transmission module according to functions, and takes charge of gathering information of images, accelerated speed and the like, encapsulating the information into data of an image, and transmitting the data of the image to a computer or a flat computer, and the software can be divided into four portions of a data extraction portion, a position and posture measurement and calculation module, a data fusion portion and a three dimensional (3D) display module, and takes charge of figuring out a relative position and a relative posture of an artificial thigh bone and acetabulum through various sensing data, improving precision and reliability of measurement and calculation through fusion of redundant data, and showing the relative position and the relative posture to a doctor in 3D mode. The real-time visualization assistant positioning system for the interior of the hip joint in the total hip replacement arthroplasty presents movement status of the thigh bone in the acetabulum and a relative position relation of the thigh bone and the acetabulum in real time, assists the doctor in visually observing installation status of the artificial thigh bone with the acetabulum during the operation process, and greatly improves success rate and operation curative effects of the total hip replacement arthroplasty.

Description

technical field [0001] The invention relates to the technical field of medical electronics, in particular to a real-time visual auxiliary positioning system inside the hip joint during total hip joint replacement. Background technique [0002] Since the 1960s, artificial joint replacement has gradually developed in my country and has become a blessing for countless patients with joint diseases. Taking hip replacement as an example, the first indication is osteoarthritis, followed by aseptic necrosis of bone (such as femoral head necrosis, etc.), some hip fractures (such as femoral neck fracture), rheumatoid joint Inflammation, traumatic arthritis, benign and malignant bone tumors, ankylosing spondylitis, etc., are widely used. Coupled with today's aging population, the number of patients with osteoarthritis is on the rise, and more and more artificial joint replacement operations are performed in hospitals every year.

[0003] However, there is still room for improvement in hip replacement surgery

In today's hip replacement surgery, the process of inserting the femoral head prosthesis into the acetabulum depends entirely on the surgeon's experience. The doctor cannot intuitively see the movement of the femoral head prosthesis in the acetabulum, and cannot accurately Confirm that the femoral head prosthesis is in place in the acetabulum

If the installation position of the prosthesis is not correct during the replacement, it may lead to limited movement of the patient after surgery or dislocation of the pseudo-joint. In the light case, the long-term uneven force on the prosthesis will accelerate wear and tear, resulting in a shortened service life of the prosthesis. reduce

Generally speaking, a successful artificial hip replacement operation can provide patients with artificial hip replacement for 20 years or even longer; The service life will be sharply reduced to 7-8 years or even shorter
