Apparatus, system and method of ultrasonic power delivery in a surgical system
The disclosed apparatus, system and method may include at least a phacoemulsification surgical console having a customizable non-linear custom phacoemulsification mode. The apparatus, system and method may include an ultrasonic delivery tip; a foot pedal; and non-transitory computing code resident on a computing memory associated with a computing processor which, when executed by the processor, causes to be executed the steps of: receiving a percentage actuation of the foot pedal; calculating, including from a non-linear algorithm, a percentage actuation for the ultrasonic delivery tip corresponded to the received percentage foot pedal actuation; and dictating the calculated percentage actuation for the ultrasonic delivery tip actuation to the ultrasonic delivery tip.
1. A method of providing a customizable, non-linear custom mode for ultrasonic power in ophthalmic surgery, comprising:
receiving a first foot pedal actuation percentage from an ophthalmic surgery console;
relationally comparing the first foot pedal actuation percentage to a non-linear custom zone algorithm which is calculated from at least one user-indicated set point for ultrasonic power corresponded to a second foot pedal actuation percentage;
calculating an ultrasonic power from the non-linear custom zone algorithm based on the first foot pedal actuation percentage; and
wherein the calculation of the non-linear custom zone algorithm comprises:
applying a multiplicative factor to the at least one user-indicated set point that is back-calculated to the user-indicated set point from a maximum power level for the ultrasonic power level; and
further comprising controlling an ultrasonic delivery tip of the ophthalmic surgical console according to the calculated ultrasonic power.
2. The method of claim 1 , wherein the non-linear custom zone algorithm is applied only within a custom zone for the foot pedal actuation percentage.
3. The method of claim 2 , further comprising applying a linear algorithm outside the custom zone.
4. The method of claim 1 , wherein the at least one set point comprises at least two set points.
5. The method of claim 1 , wherein the non-linear custom zone algorithm comprises a start-segment calculation, a performance-segment calculation, and an end-segment calculation.
6. The method of claim 5 , wherein the start segment calculation obeys:
Y =( Y 1 /X 1)* X
wherein Y is the calculated ultrasonic power,
X is the foot pedal actuation percentage,
X1 is a percentage foot pedal set point, and
Y1 is a power level percentage actuation set point corresponded to X1.
7. The method of claim 6 , wherein the performance segment calculation obeys:
Y =[( Y 2 −Y 1)* X+X 1 *Y 2 +X 2* Y 1]/( X 2− X 1)
wherein X2 is a second percentage foot pedal set point, and Y2 is a second power level percentage actuation set point.
