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 method for controlling an energy output setting of a lithotripsy device during a lithotripsy procedure, the method comprising:
- receiving, from a temperature sensor positioned at a first location, temperature feedback data that indicates a temperature of an irrigation fluid during the lithotripsy procedure;
- determining an estimated temperature at a second location based on (i) the temperature feedback data and (ii) an amount of energy emitted from the lithotripsy device per unit net volume of the irrigation fluid;
- and
- modulating, during the lithotripsy procedure, the energy output setting based on the estimated temperature at the second location.
A system comprising:
- a lithotripsy device configured to emit energy at a first location inside a body of a patient;
- a temperature sensor configured to generate temperature feedback data that indicates a temperature of an irrigation fluid being supplied to the first location;
- and
- a controller configured to:
- determine an amount of energy emitted by the lithotripsy device within a particular duration of time per unit net volume of the irrigation fluid;
- determining an estimated temperature at a second location different from the first location based at least in part on (i) the temperature feedback data and (ii) the amount of energy emitted from the lithotripsy device per unit net volume of the irrigation fluid;
- and
- modulate an energy output setting of the lithotripsy device during a lithotripsy procedure based on the estimated temperature at the second location and the temperature feedback data.
A system comprising:
- a lithotripsy device;
- a temperature sensor configured to generate temperature feedback data that indicates a temperature of an irrigation fluid;
- a flow sensor configured to generate flow rate data that indicates a flow rate of the irrigation fluid;
- and
- a controller configured to:
- determine an amount of energy emitted by the lithotripsy device within a body of a patient within a particular duration of time per unit net volume of the irrigation fluid;
- modulate an energy output setting of the lithotripsy device during a lithotripsy procedure based on the temperature feedback data, the flow rate data, and the amount of energy emitted from the lithotripsy device per unit net volume of the irrigation fluid;
- and
- generate a control signal to the lithotripsy device to cause emission of energy in accordance with the modulated energy output setting.
