Abstract

Disclosed is a medical blunt bent needle. The medical blunt bent needle comprises a rotating tube, a rotating rod, a carrying ring, a spring, a lead wire, a hook, first pin shafts, a clamping plate, second pin shafts, a straight tube and a fine needle; the bottom of the carrying ring is welded with the spring, and the lower end of the spring is welded onto the rotating tube; the upper end of the lead wire is welded to the carrying ring, the lower end of the lead wire is welded onto the rotating tube, and the lead wire is arranged inside the spring; the right of the spring is welded with the hook; the upper end of the rotating rod is mounted inside the rotating tube, and the lower end of the rotating rod is mounted onto the straight tube; the circumference of the rotating tube is provided with the first pin shafts, and the inside of the upper end of the clamping plate is provided with first hollow-out units clamping the first pin shafts. The medical blunt bent needle has the advantage of being capable of adjust the direction of the fine needle.

Description

technical field [0001] The invention relates to a medical blunt curved needle, which belongs to the technical field of medical equipment. Background technique [0002] Filiform needles are made of metal, and stainless steel is the most commonly used material for making needles. Stainless steel filiform needles have high strength and toughness, straight and smooth needle body, heat-resistant and rust-proof, and are not easily corroded by chemicals, so they are widely used clinically. None of the filiform needles in the prior art has the function of adjusting the orientation of the filiform needle head. In order to solve the above difficulties, it is necessary to develop a medical blunt curved needle capable of adjusting the orientation of the needle head. Contents of the invention [0003] The purpose of the present invention is to provide a medical blunt curved needle. [0004] The problem to be solved by the present invention is that none of the filiform needles in the...
