Abstract

An ultrasound-guided nerve block device is composed of a hollow sleeve, a hollow needle core is arranged in the sleeve tube, a needle point is provided on the top of the needle core, the needle point protrudes from the top of the sleeve tube, and a needle point is provided on the inclined surface of the needle point. The micro-tooth structure has a concave-convex structure on the outer surface of the needle core close to the needle tip. There are multiple side holes on the side wall of the front end of the cannula. Several holes parallel to the long axis of the cannula are embedded in the cannula to enhance ultrasonic imaging. effect, X-ray-proof material, a rubber plunger is arranged in the tail end of the casing, and a side pipe is also arranged at the tail end of the casing, and the side pipe is arranged at the front end of the rubber plunger, and the side pipe and the casing connected. The present invention can complete continuous peripheral nerve block under the guidance of ultrasound, wherein the ring surface of the needle point is in a jagged structure, and the outer surface of the needle core is provided with a concave-convex structure, which can enhance the effect of light reflection and development, and can be used under the guidance of ultrasound. Developing, simple operation, higher accuracy, less prone to nerve damage.

Description

Technical field: [0001] The present invention relates to articles for human life, in particular to medical instruments, in particular to trocars, and in particular to a nerve block device which is beneficial to ultrasound guidance. Background technique: [0002] The continuous peripheral nerve block technique can achieve the effects of prolonged anesthesia, postoperative analgesia and sympathetic nerve block according to the needs of the operation, and at the same time can realize divided administration, thereby reducing the risk of local anesthetic poisoning. It has been widely used in clinical anesthesia and pain treatment, and it is also one of the main methods of multimodal analgesia. In order to reduce the complications of anesthesia, modern anesthesia has entered the era of visualization, and ultrasound has been widely used in various methods of anesthesia. Traditional nerve block can be completed by anatomical positioning blind detection method or nerve stimulator po...
