Radio-frequency pen-holding type stereotactic puncture device for trans-round-hole puncture for trigeminal neuralgia

Abstract

The present invention provides a radio-frequency pen-holding type stereotactic puncture device for trans-round-hole puncture for trigeminal neuralgia. The radio-frequency pen-holding type stereotacticpuncture device for trans-round-hole puncture for trigeminal neuralgia mainly comprises a gradienter electronic displayer, a pen holder body part, a radio-frequency puncture needle, a propeller and ascrewing-off part. The gradienter electronic displayer is connected with a tail part of the pen holder body by welding, the pen holder body part is provided with a threaded connection part which candivide the pen holder body into an upper part and a lower part, and the propeller fixes the radio-frequency puncture needle by a propeller bayonet. The radio-frequency pen-holding type stereotactic puncture device for trans-round-hole puncture for trigeminal neuralgia integrates stereotactic positioning and the radio-frequency puncture needle into a whole, can more intuitively display puncture angles and puncture depths, has a specific design so as to ensure that fixing puncture points and puncture depths are not changed in use, also better solves problems of positioning puncture devices usedin the past, solves more practical operation problems in round-hole positioning and puncturing processes, increases accuracy of round-hole puncturing and positioning, shortens puncturing and operatingtime, and has reasonable structural design, simple manufacture, low cost and convenient operation, and is suitable for popularization and application.

Description

technical field [0001] The invention belongs to medical auxiliary equipment, and relates to a positioning and puncture auxiliary device used for round hole puncture under the guidance of CT during radio frequency ablation for the clinical treatment of trigeminal neuralgia (secondary maxillary neuralgia), in particular to a trigeminal neuralgia The radiofrequency pen-holding stereotaxic puncture device for neuralgia puncture through round holes can fix the puncture point, ensure that the puncture point does not move during the puncture process, and accurately display the angle and depth of round hole puncture. Background technique [0002] Trigeminal neuralgia refers to spontaneous or touch-induced, repeated paroxysmal electric shock-like or lightning-like severe pain in the innervated area of ​​the trigeminal nerve, known as "the best pain in the world". The pain is mainly located in the frontal face, zygomatic region, and mandible, which can be induced by factors such as sp...

AI Technical Summary

Problems solved by technology

In the past, a puncture stereotaxic device consisting of a semicircular protractor, a spirit level, and a base was often used to assist the positioning and puncture of the round hole under the guidance of CT. , and cannot display the puncture depth, lack of fixed puncture point equipment

In addition, because the positioning device and the puncture needle are separated, the operator needs to hold the semicircular stereotaxic device in the left hand and the puncture needle in the right hand. During the scanning process, it may be necessary to perform repeated CT scans to determine the puncture depth, etc.

The above factors prolong the puncture operation and operation time
