Navigation system for orthopedic surgery

Abstract

The invention provides a navigation system for orthopedic surgery, the navigation system comprises a first navigation piece which is provided with a plurality of laser distance measuring sensors and a first indication part; a second navigation part which is provided with a plurality of positioning protrusions in a staggered manner; a navigation device which is used for receiving a plurality of externally input first numbers and second numbers, the laser distance measuring sensors corresponding to the first numbers are controlled to carry out laser distance measuring, and the distance measuring results serve as initial relative distances between the laser distance measuring sensors and the positioning protrusions; processing according to a fracture virtual reduction result to obtain a target relative distance between each laser distance measuring sensor and the positioning protrusions; when the relative position between the first navigation piece and the second navigation piece is adjusted in the fracture reduction operation process, navigation indication signals are obtained through comprehensive processing according to all the initial relative distances and the target relative distance and are given out through the first indication part. The navigation system has the beneficial effects of simple structure and low manufacturing process requirement, the navigation cost can be reduced effectively, the navigation system has general applicability and is convenience in popularization and use.

Description

technical field [0001] The invention relates to the technical field of surgical navigation, in particular to an orthopedic surgical navigation system. Background technique [0002] With the rapid development of computer and image technology, we can perform more and more surgical operations with the help of computers. Especially in trauma orthopedics, doctors can perform fracture reduction and fixation with the help of preoperative or intraoperative images. Combining the use of computers and other information technologies in clinical practice will undoubtedly be the future development trend. [0003] Most of the existing orthopedic surgical navigation technologies need to take multiple tomographic images, and perform real-time processing on the tomographic images to realize surgical navigation. A tomographic image is obtained by scanning a human body with an X-ray beam, and the shooting of multiple tomographic images may cause harm to both the patient and the doctor. [00...
