Ultrasonic visible needle knife

The invention discloses an ultrasonic visible needle knife which comprises a handheld part, a needle knife handle and a needle knife handle, the top end of the needle body is fixedly connected with the handheld part, and a cutting edge is arranged at the tail end of the needle body; the piezoelectric ceramic is arranged in the tail end, is connected to an external ultrasonic generation circuit through a wire, and is used for generating an ultrasonic signal at the tail end, so that ultrasonic detection equipment identifies and displays the depth of the tail end; the ultrasonic transmission medium extends from the top end to the tail end in the axial direction of the needle body, is connected with an external ultrasonic source and is used for transmitting ultrasonic waves to the tail end, so that ultrasonic detection equipment identifies and displays the depth of the tail end. The display definition of the needle-knife on the B-ultrasonic detection equipment can be improved, and the operation precision of the n
