Virtual knee arthroscopic surgery device

Abstract

The invention relates to a virtual knee arthroscopic surgery device which comprises a base and two operating arms, wherein each operating arm comprises a first bracket, a second bracket and an operating head; the operating head comprises a first frame, a second frame, a first angular displacement sensor, a second angular displacement sensor, a third angular displacement sensor, a linear displacement sensor, a fixed block, a first connecting guide rod, a second connecting guide rod, a third connecting guide rod and a fourth connecting guide rod; the first frame and the second frame are rotatably connected with each other through the third connecting guide rod and the fourth connecting guide rod; the fixed block is rotatably connected with the first frame through the first connecting guide rod and the second connecting guide rod; the second angular displacement sensor is installed on the fixed block; and the rotating end of the second angular displacement sensor is connected with the guide rail of the linear displacement sensor. The invention can flexibly adjust the position and angle of the surgical knife and the endoscope according to different users and different operation habits, thereby achieving the effect of realistically simulating the arthroscopic surgery, and shortening the training time for surgery doctors.

Description

technical field [0001] The invention belongs to the field of virtual operation equipment, in particular to a device for virtual knee arthroscopic operation. Background technique [0002] Virtual surgery, also known as surgical simulation, is the application of virtual reality technology in the medical field. Virtual reality technology realistically shows the anatomical structure, anatomical position, physical characteristics and physiological characteristics of the human body through the realistic rendering method in computer graphics, and simulates various phenomena that may be encountered during the operation, providing doctors with a virtual At the same time, through interactive equipment, doctors can perceive the interaction with virtual organs and complete the simulation of surgical procedures by interacting with virtual human organs. The virtual surgery system can be used by doctors for surgical training, surgical planning and even assisting real surgical treatment. ...

AI Technical Summary

Problems solved by technology

How to provide a better way to train and educate arthroscopic surgery operators to shorten the time and cost of knowledge acquisition has become an urgent problem in this field. The arthroscopic surgery training system based on virtual reality technology can be carried out anytime and anywhere Training, the use cost is very low, no doubt it has high use value for the development and promotion of surgical technology, but the current domestic research on virtual knee arthroscopy surgery is mostly in the software development stage, and the development of hardware interactive equipment is seriously lagging behind, which has become a major problem for this joint. A major obstacle to improving the level of virtual training in endoscopic surgery
