A puncture needle assembly used in trigeminal nerve semilunar compression operation

Abstract

The invention relates to surgical instruments used in the trigeminal gasserian ganglion oppression surgery and provides a puncture needle assembly used for the trigeminal gasserian ganglion oppression surgery. The puncture needle assembly comprises a puncture needle tube, a first needle core, second needle cores and a sacculus tube, the puncture needle tube comprises a main needle tube and a needle handle, and the needle handle is provided with an inner cavity; the sacculus tube comprises a contrast agent filling valve, a catheter and a sacculus, and the contrast agent filling valve is connected with the sacculus through the catheter; the front end of the main needle tube is a smooth blunt portion, the needle head ends of the second needle cores and the needle head end of the first needle core are circular-arc-shaped blunt portions, and the main needle tube is sleeved with a first detachable fixing device which is fixed to any position of main needle tube; a second fixing device for detachably fixing the catheter is hinged to the needle handle. The puncture needle assembly is novel and reasonable in structure, on one hand, the first fixing device can be utilized for positioning the stretching length of the main needle tube, on the other hand, the second fixing device can be utilized for fixing the catheter, and oppression accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of neurosurgical medical instruments, in particular to a surgical instrument used in compression of the trigeminal nerve semilunar joint. Background technique [0002] In the early 1980s, Mullan and Lichtor invented the "percutaneous balloon compression of trigeminal ganglion (PBC)" on the basis of improving Shelden and Taarnhoj's craniotomy nerve compression technique. The PBC method avoids the mortality and complications of craniotomy to a large extent because it does not require craniotomy, and the initial research results show that PBC technology has a high success rate, is safe, and is not easy to relapse. At the same time, it is favored and widely used by doctors and patients. At present, PBC technology has been considered as one of the first-choice methods for the treatment of trigeminal neuralgia in the elderly in many western countries. [0003] According to current reports, in patients with pear-...
