Abstract: A cannula assembly having a retractable cannula tip for use in ophthalmic surgical procedures is disclosed. The apparatus may include a housing having a valve bay disposed between its proximal and distal ends, and a cannula assembly, including an inner and outer tube, that extends from the distal end of the housing. The inner tube may include an elongated portion with a cannula tip at its distal end. The apparatus may further include a valve disposed in the valve bay of the housing. The valve may comprise a valve tubular for adjusting flow through the inner tube, and an actuator for moving the cannula tip from an extended position to a retracted position in the outer tube. The valve tubular may provide a biasing force to the inner tube in the retracted position to move the inner tube back to the extended position upon release of the actuator.

Abstract: Certain embodiments provide a surgical instrument comprising a hand-piece, an outer tube having a proximal end coupled to a distal end of the hand-piece, an inner tube housed within the outer tube and having a distal end coupled to a soft tip and a proximal end coupled to an actuator, and a valve housed inside the hand-piece and coupled to the proximal end of the actuator. Retraction of the actuator is configured to compress the valve and retract the soft tip into a distal end of the outer tube, such that the soft tip at least partially extends beyond the distal end of the outer tube when the valve is in an uncompressed state and at least partially retracts into the distal end of the outer tube when the valve is a compressed state.

CPC classification number: A61F9/00763
Abstract: Particular embodiments disclosed herein provide a rotational cutter for delaminating a membrane from a retina of an eye. The rotational cutter may comprise a first shaft and a second shaft comprising a blade portion, wherein the second shaft is coupled to a driver that is configured to at least partially rotate the second shaft relative to the first shaft, wherein rotating the second shaft rotates the blade portion for delaminating the membrane. The rotational cutter may also comprise a bottom portion configured to interface with a surface of the retina, wherein the bottom portion comprises one or more curved edges.
