Modulated pulsed ultrasonic power delivery system and method

摘要

A method and apparatus for delivering energy during a surgical procedure such as phacoemulsification is provided. The method and apparatus include applying energy during at least one pulsed energy on period, typically sufficient or intended to rapidly induce and beneficially employ transient cavitation. Applying energy during the pulsed energy on period comprises applying energy during a first high energy period, and applying energy during a second nonzero lower energy period.

1. A method for delivering energy during a surgical procedure, comprising:
applying energy during a modulated energy delivery period, comprising,: applying energy during a plurality of short burst periods, said short burst periods comprising a nonzero first energy burst period followed a predetermined time thereafter by a nonzero second energy burst period; and refraining from applying energy after the nonzero second energy burst period; wherein energy provided during said nonzero second energy burst period is lower in amplitude than energy provided during said nonzero first energy burst period.
