Intraoperative real-time tracking method and system

Abstract

The invention provides an intraoperative real-time tracking method. The intraoperative real-time tracking method comprises the following steps: S1, acquiring an ultrasonic bone image of a bone at a specified part; s2, acquiring a preset three-dimensional skeleton static image of the skeleton of the specified part; and S3, performing registration fusion on the ultrasonic skeleton image and the preset three-dimensional skeleton image to obtain position information of the skeleton of the specified part. According to the intraoperative real-time tracking method, the accuracy of position detection is improved, wound injury and radiation are avoided, the limitation of obtaining the ultrasonic bone image is few, and the cost is low. In addition, the invention further provides an intraoperative real-time tracking system.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an intraoperative real-time tracking method and system. Background technique [0002] Advances in digital medical technology have advanced the development of innovative medical devices and equipment to improve clinical outcomes. Numerous clinical follow-up studies have confirmed that precise surgical treatment can improve postoperative outcomes and reduce the incidence of postoperative complications. Therefore, many manufacturers have also developed many intraoperative navigation devices to achieve high-precision osteotomy, orthopaedic and prosthesis implantation or positioning. Most of the current navigation in surgery uses optical positioning and tracking technology to track the spatial position of bones during surgery. By rigidly connecting the target bone and the reflective ball array rigid body with bone nails, the real-time follow-up of the bone position ...

AI Technical Summary

Problems solved by technology

[0006] Additional trauma, the navigation preparation process requires the use of bone nails, opening holes in the patient's bone to fix the sensor array rigid body, which will cause additional puncture trauma to the patient, and the additional trauma will bring the risk of infection for the patient and postoperative pain And other issues

[0007] The point taking and positioning registration link in the operation requires complicated operation and confirmation, which will also consume a lot of time for the doctor, resulting in prolonged anesthesia time for the patient, increased blood loss, and decreased surgical efficiency.
