System and method for modulated surgical procedure irrigation and aspiration

摘要

A method and apparatus for performing modulated fluid delivery and aspiration during a surgical procedure such as phacoemulsification is provided. The method and apparatus include delivering fluid and/or aspirating fluid in a modulated or pulsed manner during a surgical procedure, including applying fluid and/or aspirating fluid in connection with ultrasonic energy at a level and for a time period sufficient to induce transient cavitation. Fluid may be applied and/or aspirated at a timing sequence and duty cycle similar to or different from application of ultrasonic energy delivery.

1. A method for delivering fluid to an ocular region during a phacoemulsification procedure, comprising:
irrigating the ocular region by applying a series of modulated fluid pulses to the ocular region via a tubing deformation fluid control device configured to selectively deform and substantially close irrigation tubing to provide fluid to the ocular region; and delivering modulated ultrasonic energy to the ocular region simultaneous with said irrigating; wherein selectively deforming and substantially closing irrigation tubing occurs in a controlled nonrandom manner such that fluid is provided in fluid pulses transmitted according to a timing scheme calculated based on a modulated ultrasonic energy delivery timing scheme.
