Abstract

The invention discloses an accurate puncture needle for treating trigeminal neuralgia. The puncture needle comprises: a puncture needle, wherein the puncture needle is in a thin strip shape, the frontend of the puncture needle is a needle point part, and the rear end of the puncture needle is provided with a push cover; and an outer sleeve, wherein the outer sleeve is provided with a puncture channel through which the puncture needle passes, the length of the outer sleeve is less than the length of the puncture needle, the outer sleeve is provided with a first scale display strip, and the distance between the first scale display strip and the front end of the outer sleeve is 7-8cm. The accurate puncture needle for treating trigeminal neuralgia can realize rapid and accurate puncturing.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a precise puncture needle for treating trigeminal neuralgia. Background technique [0002] When treating trigeminal neuralgia, the traditional method is to use light to locate the puncture position on the face, and then use a balloon puncture needle to puncture. This method is cumbersome to operate and prone to errors. An existing treatment method is to first carry out 3D modeling according to the customer's face shape, use 3D to print out a puncture mold (mask), open a puncture hole on the mask, locate the position and direction of the puncture through the puncture hole, and put the mask on. After wearing it on the customer's face, puncture can be used to puncture the puncture hole on the mask, and then the balloon catheter can be inserted for observation and imaging. [0003] When using a puncture needle for puncture, it is necessary to always pay attention to the depth of the p...
