Surgical navigation system and method for assisting orthopedic surgery

Abstract

The invention relates to the field of computer-assisted navigation systems and discloses a surgical navigation system and method for assisting orthopedic surgery. The surgical navigation system comprises a surgical navigation tool, a position tracker, a navigation system display screen and a workstation and is characterized by further comprising a space monitoring lens and an image processing module, wherein the space monitoring lens comprises a gyroscope module, a wide-angle distortion-free lens and a high-speed infrared camera, the high-speed infrared camera is used for capturing the change of a 3D space skeleton position, and the gyroscope module is used for calibrating the standard body position of a patient; the image processing module is used for performing 3D reconstruction on 3D motion information about 2D image data of the patient before surgery, the track of limb motion of the surgery part of the patient and the motion track of a surgical instrument. The surgical navigation system has the advantages that the surgical navigation system is precise in navigation, capable of being placed near a table, convenient to mount and rapid and simple to register.

Description

technical field [0001] The invention relates to the field of computer-aided navigation systems, in particular to a surgical navigation system and navigation method for assisting orthopedic surgery. Background technique [0002] Computer-aided navigation system has become an important part of modern surgical technology, helping surgeons to perform various complex operations more accurately and safely, and has many irreplaceable advantages in all aspects of orthopedics. Because of its accuracy, safety, low radiation and other characteristics, it has gradually been widely used in clinical practice. It can be used to guide doctors in surgical training, make surgical plans, navigate surgical instruments in real time, and reduce patient trauma. In the field of artificial joint replacement, computer-assisted, more accurate osteotomy, more precise prosthesis installation, and postoperative recovery of the line of force closer to the physiological state. [0003] At present, most o...

AI Technical Summary

Problems solved by technology

[0005] 1. The hardware equipment is huge and takes up space in the operating room;

[0006] 2. Due to the limited size of the equipment, it cannot be set up on the platform, and it is easy to block the view during use, so navigation cannot be realized;

[0007] 3. Time-consuming equipment installation and intraoperative registration;

[0008] 4. Equipment is expensive
