Precision improving method for spinal surgery computer navigation system

Abstract

The invention discloses a precision improving method for a spinal surgery computer navigation system which comprises a computer host, a video camera, an image acquisition device, a tracer, a fixed clamp, fixed nails, a pointer, a pointed cone, a route opener, a navigation intelligent machine and a register platform. Scanned images and data parameters of the image acquisition device are input into the computer navigation system, flow steps comprising A, system preparation, B, system connection, C, navigation image acquisition, D, navigation image registration, E, precision verification, F surgery operation, and the like are displayed on a computer display by picture prompt software and voice prompt software so as to indicate an operation surgeon to normally operate in real time, the operability of the navigation system and the precision of clinical operations are improved, the operation of the picture prompt software and the voice prompt software is convenient, time for the operation surgeon to suit the navigation system is shortened, and the clinical practicability is strong, thereby the invention is suitable for popularization and application.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a method for improving the accuracy of a computer navigation system for spinal surgery Background technique [0002] With the aging of the population and the development of modern transportation, spinal disorders have become common and frequently-occurring diseases that affect people's lives. Many diseases, including spinal instability, spinal fracture and dislocation, spinal deformity and spinal tumors, often require surgical treatment. However, the three-dimensional anatomical structure of the spine is complex, adjacent to important neurovascular tissues, many operations are risky and have many complications, and the clinical application is limited. The application of computer navigation system in spinal surgery can achieve precise intraoperative positioning, improve surgical accuracy, reduce surgical complications, reduce unnecessary tissue structure damage during sur...

AI Technical Summary

Problems solved by technology

[0003] However, the application of computer navigation system in spinal surgery is still in the preliminary stage, and its operation method needs to be further improved.

Although the manufacturer of the navigation system provides an instruction manual for the use of the system, it is not practical in clinical application and cannot guide the surgeon to use the system correctly

In spinal surgery, the anatomical structure of different lesion segments is different, so the operation of the navigation system is also different. If this problem cannot be solved correctly, the surgeon will not be able to operate the navigation system correctly, which will lead to a decline in the clinical accuracy of the navigation system, and even Misleading doctors to operate and increase the risk of surgery

Because of the above reasons, whether the navigation system is practical in spinal surgery is still controversial in the academic circles, which affects the clinical application of this technology
