Trigeminal nerve meniscus balloon compressor

Abstract

The invention discloses a trigeminal nerve meniscus balloon compressor which comprises a square shell, a mechanical timer installed on the upper side of the shell and a limiting rod which is located in the mechanical timer and can be clamped with an escape wheel after rotating upwards, and a piston rod is inserted into the shell rightwards and then connected with a sliding block. The sliding block is connected with the left wall of the inner cavity of the shell through a return spring connected to the piston rod in a sleeving mode, the mechanical timer is fixed to the upper side of the sliding block through a supporting rod, and a sliding groove allowing the supporting rod to slide left and right is formed in the upper end of the shell. A guide cylinder with the lower end open and the square section is installed in the middle of the sliding block, threaded rods which extend rightwards and are located on the lower side of the sliding block are rotationally connected to the left wall and the right wall of an inner cavity of the shell, an engagement mechanism capable of elastically engaging the threaded rods downwards is arranged in the guide cylinder, and the free end of a limiting rod is connected with a pull rope. The tail end of the pull rope penetrates through the guide cylinder and then is connected with the meshing mechanism, and the limiting rod swings downwards after timing of the mechanical timer.

Description

technical field [0001] The invention relates to the field of trigeminal nerve meniscus balloon compressors, in particular to a trigeminal nerve meniscus balloon compressor. Background technique [0002] One of the techniques in the minimally invasive treatment of trigeminal neuralgia is percutaneous microballoon compression. Local compression relieves possible nerve entrapment in the trigeminal ganglion, so as to achieve the purpose of treating trigeminal neuralgia. The technical point is usually to establish a channel leading to the Meckel cavity through body surface puncture, and then implant a compression device with a micro-balloon on the top into the chamber of the trigeminal ganglion, that is, the Meckel cavity. The balloon is then inflated by injecting a contrast agent to compress the trigeminal ganglion, a technique that has been used for more than ten years. But there are still some problems. First of all, it usually takes 1-3 minutes during the compression period...

Problems solved by technology

However, there are still some problems. First, the compression period generally needs to be timed for 1-3 minutes. After the time is up, it needs to be manually released. When the medical staff is busy with the operation and treatment, it is easy to forget the time, resulting in a decline in the treatment effect and even nerve-related complications.
