Furthermore, the tail part of the telescopic sleeve penetrates through the connecting seat and extends out, and the tail part of the telescopic sleeve is connected with a flange.

Furthermore, a plurality of liquid outlet holes are formed in the circumferential surface of the end part of the puncture needle body, and the liquid outlet holes are uniformly distributed in the circumferential direction.

Furthermore, the number of the movable claws is two, and the two movable claws are symmetrically arranged on two sides of the end part of the puncture needle body.

Furthermore, the tail part of the puncture needle body penetrates through the connecting seat and extends out, and the tail part of the puncture needle body is connected with the medicine injector.

Furthermore, the end part of the puncture needle body is a flat opening or a bevel cut.

Further, the fixed sleeve, the telescopic sleeve and the puncture needle body are coaxially arranged.

The utility model has the advantages that: the ultrasonic puncture needle pulls the movable claws through the connecting rod at the end part of the telescopic sleeve, the two movable claws are folded and clamp the target tissue of an organ, the bleeding problem of the organ tissue caused by inserting the puncture needle can be effectively prevented, the target tissue of the organ is clamped through the movable claws, the insertion precision of the puncture needle body is improved, and the problem of puncture position deviation is prevented.
