Navigating system and method for orthopedic operation

Abstract

The invention relates to a navigating system and method for an orthopedic operation. The navigating system for the orthopedic operation comprises an orthopedic operation navigating module and an orthopedic operation navigating device, and the orthopedic operation navigating module is installed in the orthopedic operation navigating device. In the orthopedic operation navigating module, a graphic workstation is used for operation of software and comprises a navigation software module and a single-chip microcomputer module. The navigating software module is used for conducting three-dimensional reconstruction on a two-dimensional image, photographed before the operation of a patient, on the skeleton of the operative part and three-dimensional movement information of the shapes, the positions and the movement tracks of the operative part of the patient and an operation instrument, and registration and fusion are conducted on two reconstructed three-dimensional images under the same coordinate system, and a three-dimensional navigating image is obtained; the single-chip microcomputer module has the storage function. According to the navigating system and method for the orthopedic operation, the intelligence degree can be easily improved, the use quality is improved, the maintenance cost is lowered, the service life is prolonged, and the operation can be completed more safely, more accurately and more efficiently.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a navigation system and a navigation method for orthopedic surgery. Background technique [0002] In traditional orthopedic surgery, orthopedic surgeons usually rely on the anatomical characteristics of the human body, the imaging data of the patient before surgery, and the X-ray fluoroscopy images of the patient during the operation. There is a large deviation in the positioning in the operation, which causes great obstacles to the operation. Even if the orthopedic surgeon has rich practical experience, he cannot fundamentally change the problem of poor positioning accuracy in the operation. For orthopedic surgeons with general experience, this problem will become even more serious, because if the positioning is not accurate, it is likely to lead to the failure of the operation, and even cause secondary injury to the patient. Therefore, how to avoid the in...
