Abstract
A medical laser system and associated methods for dynamically managing laser power during surgical procedures are disclosed. The system includes a laser console having a laser source, an optical coupler for delivering laser energy through an optical fiber, and a controller with a processor and memory. The controller receives operating parameters including laser on-time and off-time, and determines a temperature and/or thermal dose as a function of time based on the parameters. The thermal dose may be derived using models, lookup tables, or machine learning. The system automatically adjusts laser operating parameters, such as pulse energy or frequency, in response to the determined thermal dose to improve treatment efficiency while reducing risk of tissue damage.
Claims20
A medical laser console comprising:
- a laser source configured to generate laser light;
- an optical coupler to couple the laser light to an optical fiber;
- and
- a controller, the controller comprising at least a processor and a memory, the memory comprising instructions, when executed by the processor, cause the controller to:
- receive a plurality of operating parameters, including:
- a first time generated by a laser system, the first time corresponding to a time that a laser is on, and
- a second time generated by the laser system, the second time corresponding to a time that the laser is off;
- determine a temperature;
- and
- send a control signal to the laser source to cause the laser source to adjust one or more of the operating parameters based on the temperature.
A method of determining a thermal dose, the method comprising:
- receiving, at a controller for a surgical laser system, a plurality of operating parameters, including:
- a first time generated by a laser system, the first time corresponding to a time that a laser is on;
- a second time generated by the laser system, the second time corresponding to a time that the laser is off;
- determining, using a simulation model, a temperature prediction based on the plurality of operating parameters;
- and
- determining, during a time period, a thermal dose corresponding to the temperature prediction as a function of time.
At least one non-transitory computer-readable storage medium comprising instructions executable by a processor of a surgical laser console, which instructions, when executed, cause the surgical laser console to:
- receive a plurality of operating parameters, including:
- a first time generated by a laser system, the first time corresponding to a time that a laser source of the surgical laser console is on;
- a second time generated by the laser system, the second time corresponding to a time that the laser source is off;
- and
- determine, using a model, a predicted temperature based on the plurality of operating parameters.
