Abstract
A system and method for emulsification of particles produced during a surgical procedure is disclosed herein. Included are a surgical handpiece configured to emulsify lens material in an eye; an aspiration line coupled with the handpiece; and a surgical console communicatively coupled with the aspiration line and the surgical handpiece. The surgical console configured to estimate temperature of a tip of the surgical handpiece, and to modify at least one of ultrasound power to the surgical handpiece, a flow rate of the aspiration line, or a vacuum level of the aspiration line responsively to the estimated temperature meeting a predetermined temperature threshold.
Claims20
A phacoemulsification system, comprising:
- a surgical handpiece configured to emulsify lens material in an eye;
- an aspiration line coupled with the handpiece;
- and
- a surgical console communicatively coupled with the aspiration line and the surgical handpiece, the surgical console configured to estimate temperature of a tip of the surgical handpiece, and to modify at least one of ultrasound power to the surgical handpiece, a flow rate of the aspiration line, or a vacuum level of the aspiration line responsively to the estimated temperature meeting a predetermined temperature threshold.
A phacoemulsification system, comprising:
- a surgical console including a graphical user interface (GUI) and at least one processor configured to transmit and receive control inputs for a surgical procedure;
- a surgical handpiece having a plurality of fluidic and electrical lines communicative with the surgical console, the surgical handpiece comprising:
- a surgical tip comprising a needle and a sleeve, wherein the surgical tip is configured for emulsification of lens material in an eye;
- an ultrasonic horn configured to drive the surgical tip via the electrical line responsive to a first of the control inputs;
- one of the plurality of fluidic lines being an aspiration line from the surgical tip substantially along a length of the surgical handpiece, the aspiration line configured for aspiration of the emulsified lens material from the eye responsive to a second of the control inputs;
- and
- a second of the plurality of fluidic lines being an irrigation line from proximate to the surgical tip substantially along a length of the surgical handpiece, the irrigation line configured for irrigation of the eye responsive to a third of the control inputs;
- wherein the at least one processor is configured to read non-transitory computing code which, when executed by the at least one processor of the surgical console, causes the steps of:
- monitoring power applied to the ultrasonic horn;
- monitoring the aspiration;
- monitoring the irrigation;
- applying a model estimating a current and an upcoming temperature of the surgical tip based collectively on the monitoring steps;
- and
- providing mitigation if the current or the upcoming temperature is estimated by the model to be higher than a predetermined threshold likely to cause injury.
A computer-based surgical support method comprising executing computing code associated with a surgical console, which executing performs the steps of:
- receiving aspiration data regarding aspiration;
- receiving characteristics of a surgical procedure, including at least a power level of a surgical instrument associated with the surgery;
- applying a model estimating temperature of the surgical instrument based collectively on the receiving steps;
- and
- mitigating adverse patient effects if the temperature is estimated by the model as likely to cause injury.
