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.

Abstract: Particular embodiments disclosed herein provide a surgical instrument comprising a device having a functional end configured to be inserted into a body part, a shaft coupled to a proximal end of the device, and a shaft housing configured to receive a distal end of the shaft and operable to move along a central axis of the shaft. The surgical instrument further comprises a tube coupled to the distal end of the shaft housing and configured to partially house the device such that the functional end of the device at least partially extends beyond the distal end of the tube. The surgical instrument further comprises a plurality of arcuate levers such that pressing one or more of the plurality of arcuate levers moves the shaft housing and the tube toward the functional end of the device, causing the tube to transition the device from a deactivated state to an activated state.

Abstract: Particular embodiments disclosed herein provide a membrane delamination device for delaminating a membrane from a retina of an eye. The membrane delamination device comprises a blade, a first lever coupled to the blade, and a second lever coupled to the blade. The first lever and the second lever are at least partially housed by a first shaft of a hand-piece. The first lever is fixedly coupled to the first shaft. The second lever is fixedly coupled to the hand-piece. The blade at least partially extends beyond a distal end of the first shaft. The membrane delamination device is configured to be actuated as a result of longitudinal movement of the second lever within and in relation to the first shaft. The second lever moves longitudinally within and in relation to the first shaft due to an application of force to the second lever through the hand-piece.
