High-stability anesthesia injection device for leg surgery

Abstract

The invention discloses a high-stability anesthesia injection device for leg surgery, and relates to the technical field of local anesthesia injection. The problem that the injection depth is not accurate due to the fact that the injection depth of local anesthesia injection is subjectively judged by a medical worker is solved. The high-stability anesthesia injection device specifically comprises an injection needle tube and a bearing connecting ring, and sliding connecting grooves which are evenly distributed are formed in the outer wall of the periphery of the injection needle tube; uniformly-distributed driven connecting rods are fixedly connected to the inner wall of one side of the bearing connecting ring through screws; and driven rotating wheels are rotationally connected with the inner walls of one sides of the driven connecting rods. By arranging the driven connecting rods, the driven rotating wheels, driving connecting rods, driving rotating wheels and the sliding connecting grooves, the driven rotating wheels, the driving rotating wheels and the sliding connecting grooves in the injection needle tube rub to fix the injection needle tube, the moving distance of the injection needle tube is adjusted through rotation of the rotating wheels, so that the moving distance of the injection needle tube is more accurate, and the situation that the anesthesia effect is affected due to the fact that the anesthesia injection depth is poor due to subjective judgment of the medical worker is avoided.

Description

technical field [0001] The invention relates to the technical field of local anesthesia injection, in particular to an anesthesia injection device with high stability for leg surgery. Background technique [0002] Local anesthesia is divided into surface anesthesia, local infiltration anesthesia, regional block, intravenous local anesthesia, and nerve and nerve plexus block. Among them, the local anesthesia used for leg surgery is generally intravenous local anesthesia, which requires the use of anesthesia injection devices. At present, the current In the prior art, the anesthesia injection device for leg surgery is usually injected with anesthesia by the medical staff based on their subjective ideas and experience. Intravenous local anesthesia needs to go deep into the patient's distal vein many times, and the depth depends on the subjective judgment of the medical staff, resulting in injection The inaccurate depth affects the anesthesia effect. Therefore, there is an urgen...
