Problems solved by technology

During the puncture process, the position of the nerve slave and the puncture needle needs to be observed in real time in the ultrasound image. However, due to the physiological shaking of the human hand, slight shaking can easily cause loss of vision. Long puncture time and other problems lead to high difficulty in puncture operation and unsatisfactory anesthesia effect

Abstract

The invention discloses a handheld ultrasonic guidance nerve block robot, which comprises a clamping mechanism used for clamping an ultrasonic probe, a straight line position regulation mechanism, anarc line posture adjustment mechanism, a radial movement puncture end and a puncture control system, wherein the clamping mechanism, the straight line position regulation mechanism, the arc line posture adjustment mechanism, the radial movement puncture end and the puncture control system are connected in sequence; and the puncture control system is independently connected with the clamping mechanism, the straight line position regulation mechanism, the arc line posture adjustment mechanism and the puncture end to output a control instruction. The handheld ultrasonic image guidance nerve blockrobot with a light structure is used for assisting a doctor in finishing high-accuracy nerve block.

Description

technical field [0001] The present invention relates to a technology in the field of medical equipment, in particular to a hand-held ultrasound-guided nerve block robot for assisting precise nerve block. Background technique [0002] During the nerve block operation, the path of the puncture needle passing through the human body must be strictly controlled to avoid unnecessary damage to surrounding tissues, and the point of the puncture needle must be controlled to reach the nerve plexus accurately, and then the anesthetic drugs are injected to obtain the best anesthesia effect. In the existing manual nerve block method under the guidance of ultrasound, the doctor holds the ultrasound probe and the puncture needle at the same time, cooperates with both hands, and performs the puncture operation under the monitoring of the ultrasound image. During the puncture process, the position of the nerve slave and the puncture needle needs to be observed in real time in the ultrasound ...
