The mechanical wave is transmitted in the impact head 5 and acts on the focus through the front end of the impact head 5 to achieve the purpose of treatment.

In the present utility model, unlike the existing integrated impact head, as shown in fig. 3, the impact head 5 includes an inner core 5.1 made of metallic copper and an outer sheath 5.2 wrapping the inner core 5.1 and made of metallic chromium. Thereby, the inner core 5.1 is made of metal which is easy to penetrate by shock waves, the outer sleeve 5.2 is made of metal which can shield the shock waves, so that the energy attenuation and scattering are not easy to be caused in the transmission process of the shock waves in the shock head 5, and effective energy can be gathered at the focus part.

Thereby, a high pressure gas pipe may be connected through the gas pipe interface 9 in order to supply high pressure gas into the guide trajectory 2, thereby helping the high pressure gas to drive the bullet 3 to move at a high speed in the guide trajectory 2 and strike the impact head 5.

Preferably, a magnet 8 is provided at the end of the rear end of the guide rail 2. Thereby, when high pressure gas is not applied, the bullet 3 can be retracted to the rear end of the guide trajectory 2 under the action of the magnet 8, so that the bullet 3 can be driven to move at a high speed in the guide trajectory 2 and strike the impact head 5 when high pressure gas is applied next time.
