Novel cricothyroid membrane puncture needle

Abstract

The invention belongs to the technical field of medical instrument, and relates to a novel cricothyroid membrane puncture needle used for laryngeal of otorhinolaryngology. The cricothyroid membrane puncture needle is characterized in that the cricothyroid membrane puncture needle is provided with a circular pipe (1); a steel wire (2) passes through in the circular pipe (2); one end of the steel wire (2) is provided with a conical needle (3) and the other end of the steel wire (2) is provided with a handle (4); the conical needle (3) can slide inside the circular pipe (1) with the push-pull of the steel wire (2); the circular pipe (1) uses a 1 / 4 arc pipe; the pipe mouth of the circular pipe (1) is provided with a pipe handle (5); the conical needle (3) uses a triangular pyramid needle; the handle (4) can be a spherical shape or a ring shape; the novel cricothyroid membrane puncture needle is made of stainless steel and has the advantages of simple preparation, low cost, simple and convenient operation, exact piercing, being not easy to damage other normal tissues, good ventilation, being not easy to block the pipe, etc.

Description

Technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a new type of cricothyroid puncture needle used for the throat of otolaryngology. Background technique [0002] Patients with acute laryngeal obstruction require urgent airway patency. The traditional method is to use a thick injection needle to perform cricothyrocentesis, and breathe through the injection needle. When puncturing with an injection needle, one is easy to be blocked by body tissue; the other is that the needle hole is small and the ventilation is limited; the third is that the injection needle is vertical, and its tip is easy to pierce the back wall of the larynx and enter the esophagus, damaging other tissues of the body. Summary of the invention [0003] The purpose of the present invention is to design a new type of cricothyroid puncture needle which is simple in structure, easy to operate, safe and effective, and is conducive to medical staff in...
