Problems solved by technology

[0004] In the prior art, craniotomy is used to rescue patients with severe cerebral hemorrhage, which is extremely traumatic, and in order to accurately find the location of blood clots during the operation, surgical forceps are often needed for traction to expose the surgical field of view, and the operation is successfully completed. The surgical forceps also have certain effects on the cerebral cortex. harm

Embodiment approach

[0024]As an embodiment of the present invention, the crushing unit 3 includes a mandrel 4, a drive motor 5, a slip ring 6, a No. 1 connecting rod 7, a No. 2 connecting rod 8, a crushing claw 9 and a piston 10; 1 is provided with a mandrel 4 in the middle, and the end of the mandrel 4 away from the head of the probe rod 1 is covered with a drive motor 5, the drive motor 5 can rotate on the mandrel 4, and the shell of the drive motor 5 is made of titanium alloy; the drive motor 5 A slip ring 6 is fixedly connected to the side close to the head of the probe rod 1, and the slip ring 6 is slidably connected to the mandrel 4; a group of crushing claws 9 are evenly distributed around the side of the slip ring 6 away from the drive motor 5, and the crushing claws 9 are close to One side of the slip ring 6 is connected to the slip ring 6 through the No. 1 connecting rod 7; the No. 1 connecting rod 7 is respectively hinged with the crushing claw 9 and the No. 1 slip ring 6; a group of pi...

Embodiment 1

[0031] Example 1: Please refer to Figure 4 , when the blood clot accumulated in the brain is located next to the nerve bundle, after the probe rod 1 reaches the blood clot, with the assistance of the camera 2 and VR glasses to simulate the intracranial surgery environment, the volume of the expansion ring 15 filled with normal saline expands to spread the blood clot Near the nerve, the driving motor 5 drives the crushing claw 9 to rotate through the cooperation of the slip ring 6, the first connecting rod 7 and the second connecting rod 8, and smashes and cleans the accumulated blood clots. At the same time, the micro motor 13 in the drum 11 drives The auger 12 rotates and grinds the blood clot sucked into the drum 11, and the blood clot after the grinding is drained to the outside of the body through the suction pipe 14, so as to speed up the breaking and cleaning of the blood clot.

Embodiment 2

[0032] Example 2: Please refer to Figure 5 , when the intracranial silted blood clot wraps the nerve bundle, after the probe rod 1 reaches the position of the blood clot, with the assistance of the camera 2 and VR glasses to simulate the intracranial operation environment, the volume of the expansion ring 15 filled with normal saline expands to spread the blood clot Nearby nerves, the driving motor 5 does not work, and the micro motor 13 in the drum 11 drives the auger 12 to rotate to grind the blood clot sucked into the drum 11, and the blood clot after grinding is drained out of the body through the suction pipe 14, when the drum 11 After cooperating with the micro motor 13 and the auger 12 to open up the blood clot, the probe rod 1 is pulled back to the initial position, the angle of the cylinder 11 is adjusted through the external controller to control the drive motor 5, and then the blood clot is continued to be minced and cleaned until the blood clot is cleaned up; Barr...

Abstract

The invention belongs to the technical field of medical devices, and particularly discloses a VR simulation traction device for neurosurgery. The VR simulation traction device comprises a detection rod made of a titanium alloy material. The head portion of the detection rod is provided with a 360-degree panoramic camera. A group of high-light lamps are circumferentially and evenly distributed on the outer circle of the camera. The camera is electrically connected with external VR glasses. The camera outputs signals which are then processed by the VR glasses, and the simulation intracranial surgery environment is generated. A smashing unit is arranged in the middle of the detection rod. The smashing unit comprises a mandrel, a driving motor, a slide ring, a first connecting rod, a second connecting rod, a smashing claw and a piston. The VR simulation traction device is simple in structure, the simulation intracranial surgery environment is generated after data transmitted by the 360-degree panoramic camera is received and processed by the VR glasses, the advancing route of the detection rod is modified in real time, and the smashing unit smashes and cleans away blood clots around intracranial nerves when the detection rod reaches a preset position.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a VR simulation traction device for neurosurgery. Background technique [0002] VR, or virtual reality technology, is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. It is a multi-source information fusion, interactive three-dimensional dynamic view and entity behavior system. Simulation immerses the user in that environment. [0003] Cerebral hemorrhage refers to hemorrhage caused by non-traumatic vascular rupture in the brain parenchyma, accounting for 20% to 30% of all strokes, and the fatality rate in the acute phase is 30% to 40%. The cause of the occurrence is mainly related to cerebrovascular lesions. Patients with cerebral hemorrhage often suffer from sudden onset due to emotional agitation and exertion. The early mortality rate is very high. After the blood vessels in the brai...
