This invention provides a method for processing an ultrafine lithotripsy probe, comprising the following steps: S1. Inserting one end of the probe body into the mounting hole of the probe base to complete the initial assembly; S2. Placing the initially assembled ultrafine lithotripsy probe into a pressing device and fastening the probe body to the column of the pressing device, so that the probe base is located inside the heating coil of the heating machine; S3. Starting the heating machine to heat the probe base, and when the probe base reaches a predetermined state, using the pressing device to press the probe body into the mounting hole to a predetermined depth; S4. After pressing, removing the ultrafine lithotripsy probe and performing a cooling treatment. The ultrafine lithotripsy probe produced by this processing method has the advantages of tight assembly between the probe body and the probe base, low ultrasonic transmission loss, and the connection between the probe body and the probe base is not easily broken under high-frequency ultrasonic vibration, resulting in high lithotripsy efficiency.

Disclosed herein are a transmitting end magnetic core and a preparation method therefor. The transmitting end magnetic core comprises a magnetic core body, the magnetic core body being a flat disk structure; a winding center column is disposed on an end surface of one side of the magnetic core body, the winding center column being used for winding a magnetic induction coil; a winding groove is penetratingly disposed on the magnetic core body, one end of the winding groove being located on the winding center column or the magnetic core body, and the other end penetrating through the edge of the magnetic core body; an outer wall is circumferentially arranged at the edge of the end surface of the same side of the magnetic core body as the winding center column, at least one of two end portions of the outer wall along the circumferential direction of the magnetic core body disposed separated from the winding groove; and the end surface of the magnetic core body is smoothly connected to the side surface of the magnetic core body. The end surface of the magnetic core body of the transmitting end magnetic core disclosed in the present application is smoothly connected to the side surface of the magnetic core body, so that no damage is caused to an insulation layer of a wire; this eliminates a positioning groove on the back surface of the magnetic core body, simplifying a processing technique for the transmitting end magnetic core, and improving the yield of the transmitting end magnetic core.
