Problems solved by technology

[0004] At present, many training methods in the medical field use virtual display technology, but because of the limitations of vr glasses, you need to wear too large glasses when using them, and the resolution is also subject to certain constraints, while virtual display is not limited Yu vr glasses

Embodiment 2

[0055] Such as Figure 8 , the difference between this embodiment and embodiment 1 is:

[0056] The lifting adjustment mechanism 6 includes a synchronous belt support frame 611, a power wheel 612, a driven wheel 613, and a synchronous belt 614. Two synchronous belt support frames 611 are installed on the front end of the lifting slide rail 26, and the power wheel 612 is installed on the upper side of the synchronous belt support frame 611. , the driven wheel 613 is installed on the lower side of the timing belt support frame 611, the power wheel 612 and the driven wheel 613 are connected by a timing belt 614, and the lifting slider 25 is connected to the timing belt 614, when the virtual display screen 21 needs to be lifted , the internal motor of the power wheel 612 is started to drive the lifting slider 25 to lift through the synchronous belt 614.

Abstract

The invention discloses a neurosurgery simulation operation model based on VR technology, which comprises a feedback mechanism for detecting the dynamic state of medical staff in real time, a cooperative imaging mechanism and an adjusting mechanism for simulating and imaging the motion in real time, and is characterized in that the adjusting mechanism is mounted at the front end of a sealing mechanism, and the cooperative imaging mechanism is mounted in the sealing mechanism; a simulation skull is arranged in the center of the sealing mechanism, the feedback mechanism is arranged outside the simulation skull, and the power end of the adjusting mechanism is connected with a lifting adjusting mechanism. The feedback mechanism, and the cooperative imaging mechanism are adopted to dynamically monitor hands and instruments of medical staff in real time, so that clear virtual images can be fed back to the adjusting mechanism, the adjusting mechanism can perform real-time adjustment according to the sight of the medical staff, and the overall accuracy and practicability of the device are improved; by means of an external imaging mode and a real-time adjusting structure, use of vr glasses which are too heavy and low in resolution ratio is avoided, and the overall use degree of the device is improved.

Description

technical field [0001] The invention relates to the field of neurosurgery simulation, 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] Virtual reality technology is a new practical technology developed in the 20th century. Virtual reality technology includes computer, electronic information, and simulation technolo...
