Operation training model and manufacturing method thereof and operation navigation system

Abstract

The invention discloses an operation training model comprising a bone tissue model and a soft tissue model. The internal part of the soft tissue model has a hollow structure. The bone tissue model is fixed in the internal part of the body part and supports the soft tissue model. The invention also discloses a manufacturing method of the operation training model. The manufacturing method comprises the following steps that human body image data are acquired; the three-dimensional model of the bone tissue and the soft tissue is established; a soft tissue model mould drawing is manufactured; the bone tissue model is printed; a soft tissue model mould is printed; the soft tissue model is manufactured; and the operation training model is formed. The invention further discloses an operation navigation system comprising operation instruments, an operation instrument tracker, a training model tracker, an optical positioning tracker, a computer and a displayer. The advantages and the beneficial effects are that use of corpses can be avoided, the texture and visual authenticity of the operation training model can be restored, use of C-arm fluoroscopy in conventional operation training can be avoided, accurate information can be provided for operators and multiple operation training groups can be tracked.

Description

technical field [0001] The invention relates to the medical field, in particular to an operation training model, a manufacturing method thereof, and an operation navigation system. Background technique [0002] Traditionally, doctors or medical device companies with transforaminal mirror minimally invasive technology often use purchased cadavers or mannequins in surgical teaching and training or device promotion. In the medium operating environment, with the help of preoperative imaging film or C-arm machine in the operating room, it is repeatedly tested and confirmed to ensure the smooth progress of the training process. [0003] In the published transforaminal mirror minimally invasive surgery training system, the main problems are as follows: [0004] 1. Use real corpse models directly, but corpse resources are scarce; [0005] 2. The existing human body simulation models on the market lack a sense of reality; [0006] 3. The C-arm machine is used in the training proce...
