Embodiment Construction

[0017] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.

[0018] The embodiment of the present invention provides a construction idea of ​​a virtual orthognathic surgery training system and a method for realizing the force-tactile feedback function based on fresh jaw cutting force. The virtual orthognathic surgery training system should include: force based on fresh jaw cutting force Haptic feedback function, surgical sound simulation, surgical courseware exercise system, and 3D stereoscopic vision system.

[0019] The virtual training system for craniomaxillofacial orthognathic surgery with immersive virtual reality and force feedback function is mainly composed of five parts: high-performance graphics workstation-master computer: use software to realize data calculation and processing. Display300 three-dimensional display system: dis...

Abstract

The invention discloses a virtual orthognathic surgery training system, which mainly comprises a cutting system, a control system, a signal acquisition system and the like, wherein the jaw bone cutting system is used for jaw bone cutting operation in the case of orthognathic surgery; the control system carries out analysis and processing on cutting force data, and cutting force touch feedback is realized; and the signal acquisition system is used for acquiring cutting force data of the cutting device. Through simulating high-realistic feeling surgery cutting hand feeling, tissue cutting sound, three-dimensional stereoscopic vision and by using a 3D courseware for drilling, a research idea for the virtual orthognathic surgery training system is built, the time and the cost for surgery training are reduced, the training time for an orthognathic surgery doctor is shortened, the number of living animals or dead bodies for the training is also reduced, and considerable economic benefits are realized.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a virtual orthognathic surgery training system and method. Background technique [0002] Severe skeletal malocclusion is a serious disfiguring maxillofacial deformity. It mainly involves the upper and lower jaws and occlusal function problems. question. Virtual surgery training technology has been proved to be an effective surgical training method, especially for young surgeons with little or no surgical experience. [0003] The current virtual orthognathic surgery training system still has the following problems: (1) There is a lack of a complete set of systematic virtual orthognathic surgery training ideas. (2) The haptic feedback system that simulates tactile perception plays a very important role in the surgical virtual system and is an indispensable part of virtual reality surgery. However, in the research of virtual orthognathic surgery training, there is a lac...
