Puncture needle capable of strengthening ultrasonic development

Abstract

The puncture needle is of a circular tube-shaped structure with an inner channel, and is characterized in that a plurality of conical grooves are uniformly formed in the peripheral surface, close to a needle tip, of a needle body at intervals in the length direction, and the conical grooves form an ultrasonic reflection enhancing structure; an ultrasonic reflecting surface is formed on the surface of each conical groove, and the included angle between each ultrasonic reflecting surface and the central axis of the puncture needle ranges from 30 degrees to 60 degrees. The ultrasonic reflection enhancing structure and the tungsten-containing plating layer designed by the invention obviously improve the ultrasonic developing property of the needle point part of the puncture needle, realize accurate positioning of the needle point of the puncture needle through ultrasonic development, improve the positioning accuracy of ultrasonic development and reduce the surgical risk.

Description

technical field [0001] The present invention generally relates to the technical field of medical devices, in particular to a puncture needle capable of enhancing ultrasonic imaging. Background technique [0002] Needles are primarily used in nerve block procedures for anesthesia purposes. The traditional nerve block mainly conducts blind detection based on the anatomical landmarks of the peripheral nerve body surface, determines the target nerve according to the sensation, and then implements effective puncture. Traditional nerve blocks are often affected by factors such as obesity, individual anatomical differences, trauma, and anatomical variation, resulting in unclear anatomical landmarks on the body surface, and unable to accurately locate the nerve block site, resulting in anesthesia drugs that cannot be injected into the ideal nerve block site, resulting in blockade. Decreased stagnation success rate or unsatisfactory anesthesia effect. In response to this problem, m...

Problems solved by technology

However, the ultrasonic receiver also cannot receive the ultrasonic signal from the specular reflection on the puncture needle, which accounts for the highest proportion, and the reflected waves of the ultrasonic imaging are almost all from the diffuse reflection on the surface of the puncture needle, and the improvement effect of ultrasonic visualization is very limited.
