A 3D simulation system for endoscopic minimally invasive surgery based on 3D force feedback technology

Abstract

The invention discloses an endoscope minimally invasive surgery 3D simulation system based on the 3D force feedback technology. Based on the principle of the computer virtual reality technology, by means of an autonomously-developed 3D underlying engine platform and a spatial orientation sensor modularization assembly, through the human body system simulation and force feedback technology, the clinical surgical instrument operation hand feeding and the operating procedures are simulated through the system; based on the national initiative special 3D underlying engine platform and a software developing environment, through combination with the clinical training program, by means of a virtual human organ collision detection algorithm, a tissue deformation simulation calculation model and the like, the endoscope minimally invasive surgery 3D simulation system is established.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a three-dimensional simulation system for endoscopic minimally invasive surgery based on 3D force feedback technology. Background technique [0002] The 3D simulation platform system for endoscopic minimally invasive surgery is the core of simulation training for endoscopic minimally invasive surgery, including file management, network features, etc. The core of the 3D platform system is the 3D engine. There are open source and commercial 3D engines, and the common open source 3D engines include: Unreal, Quake, Lithtech, OGRE, Irrlicht, etc. OGRE has the highest rating among open source engines. One reason is that as a graphics rendering engine, it supports the most graphics features, so the rendering quality is also good; another reason is that The clarity of the design pattern; plus, the speed is not bad. Commercial 3D max engine, as well as foreign commercial 3D engines. Th...

AI Technical Summary

Problems solved by technology

[0003] 1. Most engines are mainly aimed at 3D simulation applications, and the simulated objects are mainly rigid bodies, while the endoscopic minimally invasive surgery simulation training targets human tissues, most of which are soft bodies

[0004] 2. The modeling method is too simple, and generally only supports models built by modeling tools such as 3Dmax

[0005] 3. It is impossible to simulate various actions of surgical instruments, or the simulated effect is too different from the actual one

[0006] 4. It cannot simulate various medical effects well, such as grasping, cutting, suturing, knotting, applying titanium clips, smoke, bleeding, etc.

[0007] 5. Generally, it is bound to Microsoft's 3D DirectX and cannot support cross-platform development and application

[0008] 6. Not enough support for the current mainstream 3D control terminals, only specific 3D control terminals can be supported
