Large animal ventricle puncture system

Abstract

The invention discloses a large animal ventricle puncture system. The system comprises a ventricular drainage device (1) comprising a base (101), a ventricular catheter (102) and an external catheterjoint (103), and the base (101) is provided with a conductive structure (108), a guiding core (2), a puncture locking cover (3) and a sealing cover (4). The system uses a flexible material pipe to becombined with a round head needle core, the flexible material pipe is, for example, a silicone pipe to ensure the rigidity of the puncture process, the damage and interference to a tissue after the puncturing are reduced, and the safety during puncturing is improved; the system is well fixed in the bone and soft tissue of the animal after an operation, is not easy to shift, has a smooth surface, and does not easily produce discomfort; there is the guiding core during the puncturing, it is avoided that a punctured and cut brain tissue and a broken brain tissue entering into a pipeline causes blockage; the puncturing depth can be evaluated according to a preoperative image, pipeline cutting is conducted, and length adjustment and locking fixing are conducted according to actual needs.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a ventriculopuncture system for large animals. Background technique [0002] The existing animal ventricle puncture drug injection system is aimed at rodent experiments such as mice and SD rats. The application process needs to be punctured into the ventricle of the animal through a directional device. Due to the small ventricles of these animals, the distance from the cortex to the ventricles is short, the brain tissue is extremely soft, and the membranous structure on the brain surface is weak, so the puncture technique is not difficult. [0003] The characteristics of the ventricles of large animals are just opposite to those of small animals. For example, in mammals such as pigs and sheep, and primates such as monkeys, the ventricles are located in the deep part of the brain, far away from the cerebral cortex. Strong, the original puncture system cannot safely and ef...

AI Technical Summary

Problems solved by technology

Secondly, when the puncture distance is slightly longer, the original system has no tube core, which may easily cause brain tissue to block the tube after puncture, affecting the effect of postoperative drug injection and drainage

In addition, the depth of the existing system is fixed, and it cannot be adjusted according to individual characteristics such as the depth and width of the ventricle of the animal to achieve a good injection or drainage effect after surgery
