Surgical navigation system, computer of performing surgical navigation method and storage medium

Abstract

The invention discloses a surgical navigation system, which comprises a space positioning and marking element on a surgical instrument, a tracer on a skeleton structure, a binocular camera and a computer, wherein the tracer is provided with a navigation tracing surface; the space positioning and marking element comprises navigation surfaces; and the binocular camera is connected with the computerand transmits collected information of the tracer and the space positioning and marking element to the computer. Computer programs are separately stored into the computer and a computer-readable storage medium. A surgical navigation method is performed and comprises the steps of generating a three-dimensional model of a skeleton and a three-dimensional model of the surgical instrument and obtaining tracer registration information and calibration information of the space positioning and marking element; receiving real-time information, collected by the binocular camera, of the tracer and the space positioning and marking element; and calculating space position information of the skeleton and the surgical instrument, and carrying out real-time fusion on the space position information and thethree-dimensional models to obtain a dynamic image of a real-time position relationship between the skeleton and the surgical instrument. According to the surgical navigation system, surgical navigation is achieved and intraoperative registration is not needed, so that the surgical process is simplified and the surgical accuracy is improved.

Description

【Technical field】 [0001] The present invention relates to the technical field of medical devices, in particular to an orthopedic surgery navigation system that can be used in orthopedic surgery, and in particular to an orthopedic surgery navigation system that uses a combination of 3D printed tracers and optical positioning technology and an implementation of navigation methods Computers and storage media. 【Background technique】 [0002] With the continuous development of modern medicine and computer technology, medical imaging technology and computer image processing technology are gradually being applied in the medical field. Computer-assisted surgery technology has become a main development direction in surgery. Scope, breaking through the boundaries of traditional surgery, redefining the concept of surgery and surgical instruments. It is very important to improve the accuracy of surgical positioning, reduce surgical injury, reduce operation time and improve the success ...

AI Technical Summary

Problems solved by technology

The tracers currently used are all pre-designed structures. On the one hand, they need to be fixed near the bone structure of the surgical site, requiring an additional position, expanding the open area, increasing the pain of the patient and the difficulty of the operation. On the other hand, they cannot be used very well. With different bone structures, it is difficult to fix, which may cause a decrease in navigation accuracy and secondary damage during the operation

With this technology, fluoroscopic image registration is required during the operation, which increases the operation time, and the medical staff and patients are exposed to more radiation during the operation. The fluoroscopy process requires the use of a C-arm X-ray machine, which takes up a lot of operating time. The space is large, which is not conducive to the promotion and use of small hospitals

[0008] The current navigation system for orthopedic surgery has the disadvantages of inconvenient, unstable and minimally invasive fixation of the navigation tracer, or the problem of complex positioning of surgical instruments. During surgery, the process of perspective registration is generally necessary, requiring a large Surgical space, the registration process also prolongs the operating time and exposes staff and patients to additional radiation
