Abstract
The present disclosure relates to a stacked multi-disk pump for the pumping of ocular fluid and/or tissue during ophthalmic surgery. The stacked multi-disk pump includes an inlet port, a stacked multi-disk assembly, a fluid chamber, a central hub, a motor, and an outlet port. The motor and the hub induce the multi-disk assembly to rotate. As the multi-disk assembly rotates, the fluid is propelled into the inlet port, progresses axially, circumferentially, and radially through the stacked multi-disk assembly, and flows out the outlet port. The pump may be incorporated, for example, into the handpiece of an ophthalmic surgical instrument or a surgical console.
