Ultrasound-guided nerve block puncture equipment

Abstract

The invention discloses ultrasound-guided nerve block puncture equipment which comprises a grip and an ultrasonic probe, the top and the bottom of the grip are rotatably connected with a first circular ring and a second circular ring respectively, one side of the first circular ring and one side of the second circular ring are fixedly connected with connecting plates, and moving plates are slidably connected in the two connecting plates, and fixing devices are arranged on the two sides of the two connecting plates and the moving plate. Acording to the ultrasound-guided nerve block puncture equipment, by adjusting the angle and the height of the needle head until the needle head finds a required blocked nerve, the extrusion plate is loosened, the stress plate is restored under the action of resilience force of the third spring, the fourth rack and the third rack are clamped, that is, the connecting plates and the movable plates are fixed, at the moment, the appropriate inclination angle of the sleeve is found, the simulated puncture needle is taken out, the puncture needle is put in, and then the local anesthetic can be accurately injected beside the nerve trunk, the nerve plexus or the ganglion needing to be blocked.

Description

technical field [0001] The invention relates to a nerve block puncture device, in particular to a nerve block puncture device guided by ultrasound. Background technique [0002] Nerve block refers to the injection of local anesthetic around the nerve trunk, plexus, and node to block its impulse conduction and produce anesthesia in the innervated area. The sound energy has many applications in medicine. Under the guidance of ultrasound, the nerve that needs to be blocked can be specifically known, and it is convenient to puncture the nerve. [0003] However, when the nerve is blocked and punctured under the guidance of ultrasound, the operator needs to hold the ultrasound probe in one hand and the puncture needle in the other. However, the ultrasound probe and the puncture needle may not be in the same plane, so the puncture needle or nerve image cannot be found Not optimal, so the local anesthetic cannot accurately reach the area that needs to be blocked. Therefore, we pro...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a nerve block puncture device under the guidance of ultrasound to solve the problem that the operator needs to hold the ultrasound device with one hand and the puncture needle with the other hand when the nerve block puncture is proposed in the background technology under the guidance of ultrasound. However, the ultrasound probe and the puncture needle may not be in the same plane, so the puncture needle cannot be found or the nerve image is not optimal, so the local anesthetic cannot accurately reach the area that needs to be blocked
