EYE TREATMENT SYSTEM WITH MULTIPLE PUMPS

摘要

An eye treatment system is configured for performing an ocular surgical procedure and includes an eye treatment probe (22), a treatment console (24) including a controller (30), and an eye treatment cassette (26) for coupling the eye treatment probe (22) with the treatment console (24). The eye treatment probe is configured to provide at least irrigation fluid to, and aspiration of fluid from, a subject eye (E). The cassette comprises a cassette body, first and second arcuate ramps (46, 49), and a holding tank (43). The cassette (26) has an engagement axis (AE) along which elements of the cassette are configured to generally engage with mating elements of the treatment console. The cassette's first arcuate ramp (46) is proximal a first fluidics channel (45) configured to form a first volumetric pump (41) upon engagement with the treatment console (24). Also the cassette's second arcuate ramp (49) is proximal a second fluidics channel (48) configured to form a second volumetric pump (42) upon engagement with the treatment console. The cassette also includes a holding tank fluidly that is coupled to the volumetric pumps (41, 42).
