Medical nerve block needle with resistance feedback structure and use method thereof

Abstract

The invention discloses a medical nerve block needle with a resistance feedback structure and a use method thereof, and particularly relates to the technical field of medical treatment, the medical nerve block needle comprises a needle body, a sealing tube is arranged in the needle body, the left end of the sealing tube is fixedly connected with the right end of a needle tip, a plurality of medicine openings are formed in the outer surface of the sealing tube, and the right end of the needle tip is fixedly connected with an elastic structure. The operation of compressing the elastic structure can be realized by increasing the puncture resistance of the needle tip, so that the sealing tube can be retracted into the needle body in the puncture process, the problem of blood backflow is prevented, meanwhile, the problem of failure caused by drug pollution is avoided, and when the elastic structure deforms due to resistance, the movement of a first piston can be controlled under the action of air pressure, then the resistance feedback effect can be achieved, timely adjustment of medical staff is facilitated, and the medical nerve block needle is simple in structure, easy to operate, low in manufacturing cost and good in use value.

Description

technical field [0001] The invention relates to the field of medical technology, more specifically, the invention relates to a medical nerve block needle with a resistance feedback structure and a method of use thereof. Background technique [0002] The continuous nerve block technology can realize the effects of prolonged anesthesia, postoperative analgesia and sympathetic nerve block according to the needs of the operation. It is widely used clinically, and plays an important role in relieving postoperative pain, reducing the consumption of central analgesic drugs, and accelerating postoperative recovery. Ultrasound-guided visualization technology has changed the previous blind detection mode, which is more accurate, safe, and convenient for teaching. , ultrasound guidance also brings some problems. During the operation, the operator needs to fix the ultrasound probe with one hand and operate the nerve block needle with the other hand. At this time, additional personnel ar...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a medical nerve block needle with a resistance feedback structure and its use method. The technical problem to be solved by the present invention is: The puncture pressure is detected, but it requires electricity to connect, and the price is relatively expensive. At the same time, during the puncture process, the blood is easily drawn back into the blocking needle, and the blood will dilute or pollute the drug, which is likely to cause the drug to fail. question
