The energy used for crushing by the lithotripter includes ultrasonic vibration, mechanical shock waves, electric discharge (electricity), and laser.
[0003]
There are a number of such crushing devices having different crushing energies. The reason is that, depending on the energy used, there is an unsuitable orientation, and depending on the properties and size of the calculus to be crushed, it may not be possible to crush or it may take a long time to crush. In view of the above, conventionally, an energy composite configuration as shown in the following technology has been proposed.

As a first example of an energy-combined lithotripter, there is a probe in which a powerful ultrasonic vibration probe and an electric discharge lithotripsy probe are integrated (for example, see Patent Document 1).
[0005]
As a second example of the energy-combined lithotripter, there is a probe formed of two or more powerful ultrasonic vibration probes (for example, see Patent Document 2).
[0006]
A third example of the energy-combined lithotripter is a lithotriptor formed of two or more high-intensity ultrasonic vibration probes, each of which independently controls the phase (for example, Patent Document 3). reference).

It is possible to improve and shorten the working time.
