Problems solved by technology

During the operation, due to the presence of blood and tissue on the surface of the bone, there must be a large error in the registration, which affects the accuracy of the operation.
In addition, the premise of registration through the bone surface shape is that the bone surface features are obvious, so the application of this technology is also limited to spinal surgery

Abstract

The invention provides a system and a method for orthopedic surgical instrument navigation. The system comprises: at least two near-infrared cameras, a calculation module, a position determining module, and a display module. The at least two near-infrared cameras are used to respectively acquire images of near-infrared illuminating marked points on a surgical instrument and dynamic reference in asurgery process. The surgical instrument and the dynamic reference are respectively provided with at least three near-infrared illuminating marked points. The calculation module is used to calculate to obtain three-dimensional position coordinates of the near-infrared illuminating marked points based on a binocular vision principle according to the images of the near-infrared illuminating marked points. The position determining module is used to determine positions of the surgical instrument and the dynamic reference according to the obtained three-dimensional position coordinates of the near-infrared illuminating marked points. The display module displays positions of the surgical instrument and the dynamic reference, so as to perform surgery tracking. The system and the method can accurately position intraoperative positions of surgical instrument, provide accurate and reliable navigation for orthopedic surgeries, and can effectively improve surgery success rate. The system is simplein operation, and can be applied on any infected parts of bones, and is high in applicability.

Description

Technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a navigation system and method for orthopedic surgical equipment. Background technique [0002] Traditional orthopedic surgery mainly relies on the doctor’s experience and multiple X-rays during the operation to repeatedly confirm the treatment of the affected area to complete the operation. This requires doctors to operate and excessively relies on the doctor’s experience, but the accuracy and reliability of surgical tracking are not high. The risk is greater. In addition, repeated exposure to X-rays during the operation will also expose patients and doctors to excessive radiation damage. [0003] In view of the above problems, the current related technologies track surgical instruments in real time through surgical navigation, and guide the operation, thereby reducing the difficulty of the doctor's operation and the risk of the operation to a certain extent, but the...
