Shock wave lithotripsy device having breathing trigger function

Abstract

A shock wave lithotripsy device includes a shock wave generation unit that irradiates shock waves to a stone in the body of a patient, a trigger information generation unit that generates trigger information at a time point in a breathing cycle when a focus, which is set within a movement path of the stone according to breathing, matches the stone, and a control unit that controls, on the basis of the trigger information, whether or not to irradiate the shock waves from the shock wave generation unit. The shock waves can be irradiated in response to changes in the position of the stone in the body caused by breathing.
