The invention discloses an anesthesiology ultrasound-guided nerve block puncture stent which comprises a supporting frame, a sleeve is fixedly connected to the top of the supporting frame, a supporting rod is connected to the sleeve through a fixing mechanism, a connecting rod is connected to the end of the supporting rod through a rotating piece, and a sliding block is connected to the connecting rod through a limiting assembly. The sliding block is connected with two clamping plates through a rotating assembly, the fixing mechanism comprises a fixing cavity formed in the inner wall of the sleeve, and a plurality of fixing springs are fixedly connected to the inner wall of the fixing cavity. By arranging the clamping plate, a damping rotating shaft, a limiting assembly and the like, under the action of the clamping plate, the end of a puncture needle can be stably clamped, meanwhile, the angle of the puncture needle can be adjusted by rotating the damping rotating shaft and a concave block, and the height of the puncture needle is adjusted by adjusting the position of a supporting rod in a sleeve; and the surgical requirements of stable fixation and flexible change are met.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to an ultrasound-guided nerve block puncture stent for anesthesiology. Background technique [0002] Ultrasound-guided puncture therapy is a medical method using ultrasound technology. Local anesthetic is injected around the nerve trunk, plexus, and ganglion to block its impulse conduction, so that the innervated area has an anesthetic effect, which is called nerve block. Nerve blocks require only one injection to obtain a larger area of anesthesia. However, there is the possibility of serious complications, so the operation must be familiar with the local anatomy, understand the tissue that the puncture needle will pass through, as well as the nearby blood vessels, organs and body cavities. Commonly used nerve blocks include intermediary, infraorbital, sciatic, digital (toe) nerve trunk blocks, cervical plexus, brachial plexus blocks, and stellate ganglion and lumbar ...
