Abstract
Apparatuses, systems, and method for hydraulic pumps are disclosed. Particularly, hydraulic pumps for ophthalmic surgical procedures are disclosed. Hydraulic pumps within the scope of the disclosure may include an aspiration pump. An example aspiration pump may include first and second hydraulic cylinders and a plurality of one-way valves that are operable to permit fluid flow into a first part of a hydraulic cylinder responsive to movement of a piston within the hydraulic cylinder in a first direction and operable to permit fluid to flow out of the hydraulic cylinder responsive to movement of the piston in a second direction opposite the first direction. The aspiration pump may be attached to a housing of a hand piece, or a portion of the aspiration pump may be received into the housing of the hand piece.
