Problems solved by technology

This will not only waste time, but also increase puncture injuries and complications; if the anesthesiologist reluctantly injects local anesthetics, the effect of anesthesia will be greatly reduced, and the advantages of nerve block under ultrasound guidance will be lost

Abstract

The invention discloses a puncture needle used under the ultrasound guidance. The puncture needle comprises a puncture needle body and a needle file, wherein the needle file is arranged at the tail end of the puncture needle body, and is communicated with the puncture needle body; a plurality of grooves are formed in the outer wall of the front end of the puncture needle body, and are distributed in an array manner along the length direction and peripheral direction of the puncture needle body. With the adoption of the manner, many reflection waves can be provided for a probe, and thus the puncture needle can be clearly developed and imaged.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a puncture needle used under the guidance of ultrasound. Background technique [0002] Ultrasound-guided nerve block technology is an anesthesia method in which, under the guidance of high-frequency portable ultrasound, an anesthesiologist punctures a puncture needle into the human body to reach the target nerve area, completes the injection of local anesthetic drugs around the target nerve, and produces a satisfactory anesthesia effect. This technique has the advantages of safe puncture, precise positioning, less injury, lower incidence of anesthesia-related complications, and significantly improved success rate of nerve block, and has been widely used clinically. The specific operation method is as follows: the anesthesiologist keeps the patient in an appropriate position according to the different puncture sites, first disinfects the puncture site and lays a towel, and then ...
