Abstract

The invention discloses a locating-type anesthetic needle for intraspinal anesthesia. The locating-type anesthetic needle comprises a fixed base, a connection groove is formed in the top of the fixed base, and a first sealing plate is slidably connected with the inside of the connection groove hermetically; a moving base is fixedly installed at the top of the first sealing plate, an injection cavity is formed in the moving base, and a syringe needle is fixedly installed on the inner wall of the bottom of the injection cavity hermetically; the bottom of the syringe needle separately penetrates through the inner walls of the bottoms of the injection cavity and the connection groove and extends to the position above the fixed base, and the syringe needle is slidably connected with the inner wall of the bottom of the connection groove hermetically. The locating-type anesthetic needle is simple to operate, by rotating a threaded column, the longitudinal height of the syringe needle can be adjusted, then the syringe needle is inserted in the body of a patient, a pushing rod is pushed, and the patient can be subjected to anesthesia; due to the fact that the height of the syringe needle can be conveniently adjusted, when a medical worker uses the locating-type anesthetic needle, the difficulty can be reduced, and the locating-type anesthetic needle has certain simplicity and convenience.

Description

Technical field [0001] The invention relates to the technical field of medical devices, and in particular to a positioning type anesthesia needle for intraspinal anesthesia. Background technique [0002] From a medical point of view, the meaning of anesthesia is to temporarily lose the patient's overall or partial sensation through drugs or other methods in order to achieve the goal of painlessness and provide conditions for surgical treatment or other medical examinations and treatments. Anesthesia can be roughly divided into general anesthesia and local anesthesia. The announcement number: CN207012378U discloses an anesthesia needle, which belongs to the field of anesthesia medical equipment. It solves the problem that the existing anesthesia needle cannot inject multiple anesthetics. This anesthesia needle for anesthesiology department includes a needle cylinder. The needle cylinder includes a cylinder body and a baffle plate. The baffle plate is fixed with a needle. The baff...
