Clinical positioning device for nerve block anesthesia needle

Abstract

The invention discloses a clinical positioning device for a nerve block anesthesia needle, and relates to the technical field of medical instruments. The clinical positioning device for the nerve block anesthesia needle comprises a supporting plate; a groove is formed just in the middle of the supporting plate; a spherical sliding block is glidingly connected in the groove; and a cylindrical groove is formed in the spherical sliding block. According to the clinical positioning device for the nerve block anesthesia needle in the invention, the arranged spherical sliding block slides in the groove; therefore, a needle head sleeve can be inclined in a proper angle by rotating the spherical sliding block; then, a threaded rod is rotated, so that the spherical sliding block is extruded and fixed through an extrusion block; then, an injection needle tube can be put into the cylindrical groove to perform injection; multi-angle injection of the injection needle tube can be realized; due to mutual matching among arranged supporting block, nut, screws, arc-shaped fixed blocks, spherical sliding block and cylindrical groove, an injector can be put into the cylindrical groove; then, the two arc-shaped fixed blocks are extruded by rotating the two screws; and thus, the fact that the two arc-shaped fixed blocks clamp and fix the upper side of the injection needle tube can be realized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a clinical positioning device for nerve block anesthesia needles. Background technique [0002] The meaning of anesthesia is to use drugs or other methods to temporarily deprive the patient of the whole or part of the sensation in order to achieve painless surgical treatment. Analgesics, anticholinergics and other pre-anesthesia drugs should be used before anesthesia to prevent complications such as vomiting and aspiration during anesthesia and surgery. After the patient is received in the operating room, anesthesia is performed according to the operation requirements. During the anesthesia and operation, the changes of the patient should be closely observed and necessary treatment should be carried out. [0003] During anesthesia injection, if the manual operation hand is easy to shake, the anesthesia angle of the needle will be inaccurate, and needle deviation will eas...
