[0035] Embodiment 2

[0036] This embodiment further includes: the bottom end of the connection block 4 is provided with a disassembly and assembly structure 2 , and the disassembly and assembly structure 2 includes a pressing piece 201 , a tapered hole 202 and a clamping sleeve 203 , and the pressing piece 201 is arranged on the connecting block 4 . A ferrule 203 is installed on the outer side of the pressing piece 201, and a tapered hole is formed between the ferrule 203 and the pressing piece 201. The outer wall of the pressing piece 201 is provided with an external thread, and the inner wall of the ferrule 203 is provided with an inner thread.

Embodiment 3

[0038] Embodiment 3

[0039] This embodiment also includes: a marking line 8 for assisting the operator to puncture and a foramen ovale marking 9, the marking line 8 is composed of two vertical lines and one horizontal line, and the formed marking line 8 is arranged in an "H" shape. In addition, on the side of the lateral vertical line of the marked line, there are dashed arc lines representing the temporomandibular joint and an arc curve representing the sigmoid notch of the mandible. The protruding end represents the condyle of the mandible.

Abstract

The puncture needle comprises a needle tube and a needle base, the top end of the needle tube is detachably connected with the needle base through a connecting block, a dismounting structure is arranged at the bottom end of the connecting block, and the top end of the connecting block is fixedly connected with the needle base; marking lines and oval foramen marks which assist an operator in puncturing are carved at the top end of the needle base, and limiting blocks are evenly installed on the periphery of the top of the needle base. A laser positioning lamp body is mounted in each limiting block, and limiting structures are arranged at the two ends of each limiting block. The laser positioning lamp bodies are arranged, the laser positioning lamp bodies emit light rays, one line faces the pupil, and the other line faces the upper edge of the auricle, so that the purpose of positioning and guiding puncture through the laser lamp can be achieved, and the number of the laser positioning lamp bodies is four. And meanwhile, laser lamp positioning can be met, and two-dimensional precise guide puncture can be achieved.

Description

technical field [0001] The invention relates to the field of treatment instruments for trigeminal neuralgia, in particular to a puncture needle with a laser positioning lamp used for puncturing the foramen ovale to treat trigeminal neuralgia. Background technique [0002] With the continuous development of the economic level, the tools for the treatment of trigeminal neuralgia have also been greatly improved. Trigeminal neuralgia is a common head and face pain disease. It is called "the first pain in the world". Foramen ovale puncture for trigeminal nerve meniscus radiofrequency or balloon compression surgery, as a safe non-craniotomy minimally invasive surgery, is more and more used in clinical practice, but the foramen ovale puncture technique has always been the key to this type of surgery difficulty. [0003] At present, for the classic foramen ovale puncture path, the needle insertion point is usually selected 2 cm from the corner of the mouth, and then the needle is i...
