摘要： A surgical system comprises a hand piece, an irrigation conduit in fluid communication with the hand piece to carry fluid toward a surgical site, an aspiration conduit in fluid communication with the hand piece to carry fluid away from the surgical site, a pump interfacing with the aspiration conduit, the pump to create a vacuum pressure in the aspiration conduit to draw fluid through the aspiration conduit, a vacuum relief valve in fluid communication with the aspiration conduit to relieve the vacuum pressure in the aspiration conduit, a pressure sensor to detect a pressure associated with the surgical site, a controller in communication with the vacuum relief valve and the pressure sensor to control the vacuum relief valve to decrease the vacuum pressure in the aspiration conduit when the pressure detected by the pressure sensor is less than a first pressure threshold.

摘要： A hydraulically-driven Intra-Ocular Lens (IOL) insertion tool includes a body, a chamber within the body, a first fluid port providing fluid communication into the chamber, a piston positioned within the chamber and arranged to move within the chamber in response to the introduction or removal of fluid from the chamber, and an elongated member. The elongated member includes a distal end comprising an intra-ocular lens interface and a proximal end connected to the piston such that movement of the piston within the chamber causes corresponding movement of the elongated member.

摘要： 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.
