Abstract

An aspiration flow control device includes a housing having at least one vacuum port, at least one aspiration port, and an ejection port. The at least one vacuum port is adapted to be connected to a vacuum source, and the aspiration port is adapted to be connected to an aspiration line for receiving fluids from a surgical site. The device further includes a rotating structure having at least three vanes, which structure is configured to rotate within the housing. The at least three vanes divide an enclosed volume within the housing into at least three rotating fluid collection chambers. During rotation of the rotating structure, at least one fluid collection chamber is in communication with at least one vacuum port and the aspiration port through which fluid is received, and at least one other fluid collection chamber is simultaneously in communication with the ejection port through which fluid is expelled.

Description

technical field [0001] The present invention relates to the control of aspirated fluid flow in surgical pumps, and more particularly to the control of aspirated fluid flow in cassettes used in ophthalmic microsurgery systems. Background technique [0002] This section provides background information related to the present disclosure and does not necessarily constitute prior art. [0003] Surgical procedures often require a continuous flow of fluid to and aspiration of fluid from the surgical site. In ophthalmic microsurgery, fluid may be aspirated from the procedure site using a surgical cassette into which vacuum is applied to collect the aspirated fluid. The volume of surgical cassettes used in ophthalmic surgery needs to be large enough to contain the volume of fluid that is typically aspirated during a particular procedure. However, large cartridge volumes may require an undesirably delayed vacuum build-up before effective suction can begin. Prior art systems overcome...
