FLOODED LIQUEFACTION HAND PIECE ENGINE

摘要

In various embodiments, an ophthalmic handpiece may include a handpiece body with a pulse chamber and flooded engine compartment configured to receive fluid from a surgical console through a fluid inlet port. Heated pulses from the pulse chamber and cooler fluid from the flooded engine compartment may flow through a tip into the eye. In some embodiments, the tip may be a dual lumen tip that keeps the flows from the pulse chamber and flooded engine compartment separate until they exit the tip. In some embodiments, a tip, coupled to a merging chamber where the flows may merge prior to the tip, may be a single lumen tip that directs the heated pulses and irrigation fluid simultaneously to a lens to liquefy the lens for removal from the eye.
