Extracorporeal lithotripter and double-head shock wave source thereof

Abstract

The invention relates to the technical field of extracorporeal lithotripter, in particular to an extracorporeal lithotripter and a double-head shock wave source thereof. The double-head shock wave source comprises a first shock wave source and a second shock wave source, focal points of the first shock wave source and the second shock wave source are coincided, and an included angle between a shock wave direction of the first shock wave source and a shock wave direction of the second shock wave source is adjustable. The extracorporeal lithotripter and the double-head shock wave source thereofhave advantages that lithotripsy efficiency can be improved, treatment time is shortened, and treatment frequency is decreased; by energy dispersion of shock waves passing through body tissues, injuries to kidney tissues are reduced, so that kidney injuries are reduced, and pains and complications of patients are reduced; the included angle of the shock wave sources can be adjusted aiming at different body types, so that the shock wave source can better fit bodies of the patients, and lithotripsy effects are improved.

Description

technical field [0001] The invention belongs to the technical field of extracorporeal lithotripters, and in particular relates to a double-head shock wave source of an extracorporeal lithotripter and the extracorporeal lithotripter. Background technique [0002] Electromagnetic extracorporeal shock wave lithotripters are used in extracorporeal lithotripsy. At present, the single-wave source mode is adopted. The single-shock wave source generator forms a focal area similar to a "cigar" shape, such as figure 1 As shown, only the central part of the focal area acts on the crushing of the stones, which is helpful for the crushing of the stones. The edge part is more likely to damage the organs, and the stones are prone to displacement. The energy of the shock wave must be high to effectively crush the stones, and the patient feels pain. Strong and many complications. Contents of the invention [0003] The object of the present invention is to provide a double-headed shock wav...
