Trigeminal nerve micro-balloon accurate contrast medium propeller

Abstract

The invention provides a trigeminal nerve micro-balloon accurate contrast medium propeller. Scales are arranged on the outer wall of an outer cylinder, and a nozzle and a pressure gauge interface arearranged at the front end of a cylinder body; the inner core of the propeller is a hollow cylinder body, the side wall is axially provided with a hole, after one end of the inner core of the propelleris provided with a rubber plug, the inner core of the propeller is placed in the outer cylinder, and the inner core and the outer cylinder together form a piston; a propulsion speed control rod is arranged in the inner core of the propeller, one side of the propulsion speed control rod is provided with inclined teeth facing the rubber plug, and the other side of the propulsion speed control rod is provided with threads; the inner side wall of the inner core of the propeller is provided with a groove inclined towards the rubber plug and forms an inclined sliding surface together with the inclined teeth; and when the inclined teeth slide in the grooves, the threads extend out of or retract into the hole in the side wall of the inner core of the propeller, and when the threads extend out ofthe holes, the threads are in threaded fit with the inner wall of the outer cylinder. The trigeminal nerve micro-balloon accurate contrast medium propeller can accurately and dynamically monitor the volume and pressure of a contrast medium in a balloon in a disease treatment process.

Description

technical field

[0001] The invention relates to a medical device for minimally invasive treatment of trigeminal neuralgia. Background technique

[0002] Trigeminal nerve microballoon compression technique is an important minimally invasive technique for the treatment of trigeminal neuralgia. This technology achieves pain relief by dilating a balloon in the McBurney's capsule of the trigeminal nerve, compressing the trigeminal nerve, destroying the pain-sensing fibers of the trigeminal nerve by mechanical pressure, and blocking pain transmission. In fact, in addition to the nerve fibers that control pain, there are also nerve fibers that control facial touch and masticatory muscle movement in the trigeminal nerve. Therefore, when the microballoon compresses the trigeminal nerve in the McBurney's capsule, along with the damage to the pain sensory fibers, the tactile sensory fibers and motor fibers are often also compressed and damaged together. Due to the different diameters...
