Abstract

A nerve blocking device using ultrasonic guide comprises a hollow bush. A hollow needle core is disposed in the bush. A needle tip is disposed at the top end of the needle core. The needle tip extends out of the top end of the bush. A micro-tooth-shaped structure is disposed on the slope of the needle tip. The outer surface, close to the needle tip, of the needle core is provided with a concave-convex structure. A plurality of lateral holes are formed in the lateral wall of the front end of the bush. A plurality of materials which are parallel with the long axis of the bush, can intensify ultrasonic development effect and are X-ray-tight are embedded into the bush. A rubber plunger is disposed in the tail end of the bush. A lateral tube is further arranged at the tail end of the bush. The lateral tube is disposed at the front end of the rubber plunger. The lateral tube is communicated with the bush. The nerve blocking device has the advantages that continuous peripheral nerve blocking can be completed under ultrasonic guide, reflecting development effects can be enhanced by the zigzag structure of the annular surface of the needle core tip and the concave-convex structure on the outer surface of the needle core, development under ultrasonic guide can be achieved, and the nerve blocking device is simple to operate, high in accuracy and less prone to nerve damage.

Description

[0001] Technical field: [0002] 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: [0003] 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 stim...
