A neurosurgery simulation operation model based on VR technology

Abstract

The invention belongs to the technical field of medical devices, specifically a neurosurgery simulation operation model based on VR technology; it includes an operating table, a skull cavity simulating the human skull structure, a brain tissue model simulating the human brain structure, a brain pressure plate and Based on the VR imaging display screen, the outer surface of the skull cavity is fixedly connected with a support arm, the top of the support arm is fixedly connected with a support claw, the inner side of the support claw is provided with an empty slot, and the inner top of the empty slot is installed with a first A pressure sensor; the present invention arranges the hinged plate and the first pressure sensor. When holding the brain pressure plate downward, the hinge plate starts to rotate and the first pressure sensor is squeezed. If the time is too short, it means that the person is holding the brain pressure plate The speed when moving down is too fast, which can be displayed on the display screen in time, which is convenient for the instructor to correct it in time, and improves the teaching effect. After the arm is lifted up, the supporting spring recovers and the hinged plate is pushed back to its original position.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a neurosurgery simulation operation model based on VR technology. Background technique [0002] Brain tissue retraction is a basic technique in neurosurgery. In order not to damage the brain tissue but also to obtain an effective surgical operation space, there must be appropriate standards for the placement of the brain platen, the direction of the plate head, and the pulling force. However, for an inexperienced neurosurgeon to master this technique it is necessary to understand how to use the brain compression plate in the correct manner. Using the existing 3D printing technology to print out brain tissue for teaching simulation has become the first choice of major medical schools. [0003] In the prior art, there are also technical solutions for some surgical simulation operation models, such as a Chinese patent with application number CN105185214B disclosing a neuro...

AI Technical Summary

Problems solved by technology

[0004] Although this technical scheme can perform simulated operations, some users who have undergone repeated training, after their arms are fatigued, tend to move down faster while holding the brain platen. The existing surgical simulation operation model cannot be used for long-term training. For this reason, a neurosurgery simulation operation model based on VR technology is proposed, which can detect the speed when holding the brain platen and pressing it down, which improves the training effect
