Three-stage puncture cannula assembly for trigeminal nerve meniscus balloon compression

Abstract

The invention discloses a three-stage puncture cannula assembly for trigeminal nerve meniscus balloon compression. The three-stage puncture cannula assembly comprises a puncture needle core, an anti-blocking needle core, a balloon tube and an outer cannula, the puncture needle core is of a hollow structure, the front end of the puncture needle core is sharp, and the tail end of the puncture needle core is detachably provided with a connecting base; the anti-blocking needle core is arranged in the puncture needle core in a pluggable and inserted mode, a balloon is arranged at the front end of the balloon tube, the outer sleeve is of a hollow structure, the front end of the outer sleeve is smooth and blunt, and the inner diameter of the outer sleeve is larger than the outer diameter of the puncture needle core and the outer diameter of the balloon tube. According to the invention, not only is the wound surface in the puncture process reduced, but also the operation can be carried out by adopting local anesthesia, general anesthesia is avoided, and the operation cost and risk are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a three-stage puncture sleeve assembly used for trigeminal nerve half-lunar segment balloon compression surgery. Background technique [0002] The trigeminal semilunar ganglion balloon compression operation is completed through the puncture sleeve assembly. The first step is to puncture into the foramen ovale; the second step is to find the semilunar ganglion of the trigeminal nerve in the foramen ovale; the third step The first step is to compress the semilunar ganglion to cause ischemia and necrosis of the trigeminal nerve semilunar ganglion, so as to achieve a therapeutic purpose. [0003] The puncture trocar tool that is used for clinical treatment at present is to penetrate the foramen ovale with a relatively thick puncture trocar with an internal diameter, and its main disadvantages are: (1) use this puncture trocar to perform an operation, and general a...

Problems solved by technology

[0003] The puncture trocar tool that is used for clinical treatment at present is to penetrate the foramen ovale with a relatively thick puncture trocar with an internal diameter. Surgical risks and costs; (2) The puncture needle is relatively thick, and the tip is relatively blunt, causing greater pain and greater damage to the patient; (3) It is not conducive to puncturing the McBurney's capsule (the semilunar section of the trigeminal nerve is inside it), resulting in bulbar It is more difficult for the bursa to enter the inside of the McBurney's bursa, oppressing the half-moon festival, resulting in unsatisfactory surgical results! Therefore, there is an urgent need for a puncture cannula assembly with less trauma and ideal effect for the trigeminal nerve half-lunar balloon compression surgery
