Nerve block system based on ultrasonic intelligent recognition

Abstract

The invention discloses a nerve block system based on ultrasonic intelligent recognition, the nerve block system comprises an ultrasonic probe, an insertion needle head is arranged on the ultrasonic probe, and an anti-shake progressive mechanism is connected to the ultrasonic probe. According to the invention, the speed-limiting liquid discharging mechanism and the anti-shaking progressive mechanism are matched, and position stabilization and shake prevention during liquid medicine injection and flow speed reduction of the injection amount are realized; during specific implementation, the positions of the ultrasonic probe and the insertion needle head are fixed through the anti-shake progressive mechanism before the insertion needle head goes deep into the body of a patient, and after fixation is completed, the anti-shake progressive mechanism drives and controls the amount of the insertion needle head going deep into the body of the patient, meanwhile, the position of the insertion needle penetrating into the body of the patient is detected in real time through the ultrasonic probe and is imaged on an external imaging device to prevent the insertion needle from penetrating into the position mistakes, then liquid medicine is conveyed towards the inserted needle head through speed-limiting liquid discharging mechanism, and when the liquid medicine enters the insertion needle head, the conveying force of the liquid medicine is reduced so as to prevent the liquid medicine from rapidly impacting the deep part of the insertion needle head.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a nerve block system based on ultrasonic intelligent identification. Background technique [0002] Inject local anesthetics around nerve trunks, plexuses, and nodes to block their impulse conduction and anesthetize the innervated area, which is called nerve block. Nerve blocks require only one injection to obtain a larger area of ​​anesthesia. However, it may cause serious complications. Therefore, it is necessary to be familiar with the local anatomy, understand the tissue that the puncture needle will pass through, and the nearby blood vessels, organs, and body cavities. Commonly used nerve blocks include interstitial, infraorbital, sciatic, and digital (toe) nerve trunk blocks, cervical plexus, brachial plexus blocks, and stellate ganglion and lumbar sympathetic ganglion blocks for diagnosis and treatment. Nerve blocks are often assisted by ultrasound equipment. [...
