Abstract
Systems and methods for controlling an energy output setting of a lithotripsy device during a lithotripsy procedure are provided. The system includes a laser or other lithotripsy device configured for facilitating the lithotripsy procedure, an irrigation system configured for supplying an irrigant such as saline to a surgical site, and a temperature sensor configured to provide temperature data associated with the irrigant. The system can modulate the energy output setting of the lithotripsy device based on an estimated temperature that is determined based at least in part on the temperature data and one or more other factors such as a current energy output setting or a flow rate of the irrigant.
Claims20
A system comprising:
- an energy source configured to provide treatment energy to a first location inside a body of a patient during a medical procedure;
- a temperature sensor configured to sense a temperature of an irrigation fluid being supplied to the first location;
- and
- a controller configured to:
- estimate a temperature at a second location different from the first location based at least in part on (i) the sensed temperature of the irrigation fluid and (ii) an amount of energy emitted from the energy source per unit net volume of the irrigation fluid;
- and
- modulate a flow rate of the irrigation fluid during the medical procedure based at least in part on the estimated temperature at the second location.
A method for modulating irrigation flow to a target receiving treatment energy from an energy source during a medical procedure, the method comprising:
- sensing a temperature of an irrigation fluid being supplied to a first location inside a body of a patient using a temperature sensor;
- estimating a temperature at a second location different from the first location based at least in part on (i) the sensed temperature of the irrigation fluid and (ii) an amount of treatment energy emitted from the energy source per unit net volume of the irrigation fluid;
- and
- modulating, during the medical procedure, a flow rate of the irrigation fluid based at least in part on the estimated temperature at the second location.
