Abstract

We provide a system for monitoring temperature during lithotripsy. [Solution] The system module includes a flow sensor that can be mounted alongside the irrigation fluid channel and determines the irrigation flow rate without contact with the irrigation fluid; an input means connected to the processing unit and capable of transmitting laser operating parameters that form the basis for determining the laser output that can be irradiated at the position of the light output port to the processing unit; a temperature sensor that can be mounted alongside the irrigation fluid channel and determines the temperature of the irrigation fluid without contact with the irrigation fluid; an analysis unit attached to the processing unit that numerically determines the temperature generated inside the body during laser lithotripsy at the position of the light output port based on at least the irrigation flow rate, the temperature of the irrigation fluid, and the determined irradiation laser output; and a comparison unit that compares the determined temperature with a threshold and generates a signal if it exceeds the threshold.
