Abstract

The invention discloses a medical supermicro magnetic needle device. The medical supermicro magnetic needle device comprises a shell and a needle holder, a set of open holes used for control key installation and an open groove used for being penetrated by an adjustment button are formed in the shell, the needle holder comprises an installation base assembly, a driving unit used for driving a supermicro needle-knife to move and a supermicro needle-knife assembly, the base assembly comprises a front base and a rear cover, the front base is fixedly installed in the shell, and the rear cover is fixedly installed on the tail portion of the shell. By means of the medical supermicro magnetic needle device, the defect is solved that when supermicro needle-knife insertion is conducted by a hand, pain is caused due to slow motion; the cutting speed is fast improved to a speed which cannot be reached by the hand, so that pain of the patient during cutting is greatly alleviated due to the fact that it is found out that the higher the cutting speed is, the less pain a human body feels; meanwhile, the insertion depth can be precisely controlled.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical ultra-micro magnetic needle device. Background technique [0002] At present, the ultra-micro-needle knife is used to perform minimally invasive surgery on patients. Due to the small size of the ultra-micro-needle knife and the limitations of manpower, it is difficult for doctors to accurately control the depth of the needle during the operation. It greatly affects the accuracy of the operation. At the same time, manual operation and slow needle insertion speed greatly increase the pain of the patient. Contents of the invention [0003] (1) Solved technical problems [0004] The purpose of the present invention is mainly to provide a medical ultra-micro magnetic needle device in order to solve the above-mentioned technical problems. [0005] (2) Technical solution [0006] The present invention includes a housing and a needle holder. The housing is provided...
