Abstract

The invention relates to a computer-assisted navigation system for a minimally invasive surgery on the aseptic necrosis of the femoral head, which comprises an image workstation, an optical location tracker and rigid positioning tools, wherein the image workstation is equipped with special software packages, connected with the optical location tracker, and provided with a video input interface and a video output interface; the video input interface can be connected with an image input device so as to parallelly display video images and navigation images, and the video output interface can be connected with a monitor so as to output, display and record the surgery process during a surgery; and the optical location tracker is connected with the image workstation, and used for tracking the concrete positions of registration probes, surgical tools and affected parts by infrared rays reflected by the rigid positioning tools which are fixed in the registration probes, the surgical tools and the affected parts in real time. The system can effectively complete the minimally invasive surgery on the aseptic necrosis of the femoral head, and under the condition of not affecting the surgery effect, accurately resects focuses and minimizes the damages on normal tissues.

Description

technical field

[0001] The invention relates to a computer-aided navigation system, in particular to a computer-aided navigation system for minimally invasive surgery of aseptic necrosis of the femoral head. Background technique

[0002] With the continuous progress and development of medical theory and medical technology, surgical operations are developing in the direction of precision and minimal invasiveness. However, due to various technical deficiencies in traditional medical knowledge, it is difficult to achieve high-precision, small-incision surgical solutions. Computer-aided surgery (Computer Aided Surgery, CAS) aims at the deficiencies in traditional surgery, using engineering technology to improve, assist surgery, improve the quality of surgery, and become an important part of minimally invasive surgery. The development of computer technology is very rapid, and it continues to penetrate into various fields. In the medical field, the introduction of CT, MRI and ot...
