    Abstract: Particular embodiments disclosed herein provide a surgical instrument comprising a device having a proximal end and a functional end configured to be inserted into a body part, an assembly having a proximal end and a distal end, a shaft coupled to the proximal end of the assembly, the shaft having a shaft housing, a bearing positioned around the assembly, wherein the bearing is configured to slide over the assembly, a hub having a sleeve tube. The basket comprises a plurality of grooved levers, each grooved lever having a proximal end received by the shaft housing and a distal end coupled to a tip of the basket, wherein compressing one or more of the plurality of grooved levers moves the bearing and the hub relative to the shaft and toward the functional end of the device, causing the sleeve tube to transition the device from the deactivated state to an activated state.

    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: A surgical tool with a stiffening sleeve that is dynamically retractable during surgery. The tool includes a needle or implement for performing minimally invasive surgery through a pre-placed cannula at a surgical site. A stiffening sleeve of the tool about the implement may provide an added degree of stiffness such as where the implement is particularly thin. However, an end of the sleeve is held in position at the cannula as the implement advances therebeyond for the surgery. Nevertheless, as determined by the surgeon, the implement may be further advanced with a corresponding and deliberate retraction of the sleeve into the tool body as desired.

    Abstract: Apparatuses, systems, and methods for illuminating an interior portion of an eye are disclosed herein. In an exemplary aspect, the present disclosure is directed to an apparatus for use in ophthalmic surgery. The apparatus may include a light guide including an optical fiber, a transition region, and a light sleeve. The transition region may be disposed between the optical fiber and the light sleeve for transmission of light from the optical fiber to the light sleeve such that the light sleeve is operable to emit the light at a distal end of the light sleeve.

    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.
