Abstract

The present invention provides a four-interface shock wave balloon catheter and its control system, based on the design of the four-interface catheter base structure and the corresponding catheter structure, have separate interfaces specifically designed for replenishing new fluid and discharge of fluid, enabling simultaneous replenishment and cyclic replacement of fluid within the balloon. This allows the balloon to remain in an expanded state and ensures the stability of the acoustic impedance of the fluid within the balloon as solid precipitates are removed along with the fluid, and helps to ensure the effectiveness of the surgical treatment and shorten the surgical time, and by shortening the surgical time can reduce the occurrence of intraoperative accidents and avoid surgical risks arising from the repeated inflation and deflation of the balloon 23, thereby improving the safety of the surgery.
