It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions.

As shown in figure 1, the ultrasonic lithotripsy probe can be used with an endoscope, and comprises a handle 1 with a cavity, a head shell 1-1 is arranged in front of the handle 1, an ultrasonic generator 5 is arranged in the handle 1, and a probe 2 penetrates through the handle 1, the head shell 1-1 and the ultrasonic generator 5. The probe 2 is provided with a central hole 3, the shattered calculi are absorbed into the central hole 3 by the probe 2, and the tail end of the probe 2 is connected with a negative pressure device, for example, the negative pressure device is an air pump. The back of the handle 1 is also provided with a wire jack 4 for inserting a wire and a data wire.

As shown in figures 2-3, the probe 2 comprises a first needle body 2-1 and a second needle body 2-2, wherein the first needle body 2-1 is sleeved in the second needle body 2-2, and the first needle body and the second needle body 2-2 can mutually extend and retract.

The first needle body 2-1 extends out from the front end of the handle 1, the first needle body 2-1 is provided with a step 9 and a limiting bulge 10, and the head shell 1-1 is blocked on the limiting bulge 10 of the first needle body 2-1 to prevent the axial separation. The first needle body 2-1 is sleeved with a clamp spring 7, and the clamp spring 7 is limited on the step 9.
