System and method for controlling a transverse phacoemulsification system with a footpedal
First Claim
1. An apparatus configured for use in an ocular surgical procedure, comprising:
- a handpiece having a tip configured to ultrasonically vibrate, the handpiece configured to support a plurality of operating modes comprising a first operating mode and a second operating mode, wherein at least one tip displacement parameter is allocated to the first operating mode and at least one tip displacement parameter is allocated to the second operating mode;
an engageable switching apparatus; and
a controller connected to the handpiece and the engageable switching apparatus, wherein the engageable switching apparatus comprises a footpedal and is capable of deflection, and wherein the controller is configured to;
receive input from the engageable switching apparatus, generate a tip displacement control signal to vary a tip displacement ratio of the handpiece based on the input received from the engageable switching apparatus, and transmit the tip displacement control signal to the handpiece, thereby enabling a user to dynamically adjust the tip displacement ratio, wherein the tip displacement ratio relates the at least one tip displacement parameter allocated to the first operating mode to the at least one tip displacement parameter allocated to the second operating mode, and wherein dynamically adjusting the tip displacement ratio includes adjusting a percentage of the at least one tip displacement parameter allocated to the first operating mode and adjusting a percentage of the at least one tip displacement parameter allocated to the second operating mode in real-time based on input received from the engageable switching apparatus, wherein the adjusting of the percentages of the at least one tip displacement parameters of the first operating mode and the second operating mode is relative to each other, and wherein the adjusting of the percentages is based on an amount of the deflection of the engageable switching apparatus, wherein adjusting the tip displacement ratio comprises
1) increasing the at least one tip displacement parameter allocated to the first operating mode while proportionally decreasing the at least one displacement parameter allocated to the second operating mode, or
2) decreasing the at least one tip displacement parameter allocated to the first operating mode while proportionally increasing the at least one displacement parameter allocated to the second operating mode.

Abstract
A method and system for controlling an ultrasonically driven handpiece employable in an ocular surgical procedure is provided. The method includes operating the ultrasonically driven handpiece in a first tip displacement mode, such as a longitudinal mode according to a first set of operational parameters, and enabling a user to alter the ultrasonically driven handpiece to employ a second tip displacement mode, such as a transversal or torsional mode, using a second set of operational parameters. Enabling the user to alter performance of the handpiece comprises the user being enabled to dynamically select operational parameters for the first tip displacement mode relative to the second tip displacement mode by using, for example, a switching apparatus such as a footpedal.
