Some embodiments may additionally comprise a pivot arm that may be operable to selectively engage the forward gearwheel and the reverse gearwheel to the gear rack.

Abstract: An apparatus for folding an intraocular lens or other implant before inserting it into an eye in various locations using variable surgical techniques. Some embodiments may comprise or consist essentially of a haptic folding mechanism configured to fold one or more haptics onto the top of an optic prior to the optic being folded into a nozzle. In some embodiments, a leading haptic lifter or lifting mechanism can be configured to elevate and constrain a leading haptic during implant delivery. This leading haptic folding mechanism can passively lift the leading haptic onto the top of the optic.

Abstract: An irrigation system for a surgical instrument includes an irrigation tube arranged to convey an irrigation fluid and an irrigation clip structurally arranged to receive a portion of the irrigation tube. The irrigation clip includes a proximal portion, a distal portion, a body portion, and an arm portion. The arm portion is structurally configured to selectively attach the irrigation clip to the surgical instrument and to bias the irrigation clip toward the surgical instrument with a biasing force. The irrigation clip includes a tube locking portion structurally arranged to cooperate with the surgical instrument to engage the outer surface portion of the irrigation tube to inhibit rotation and axial displacement of the irrigation tube relative to the irrigation clip in response to the biasing force.

Abstract: An apparatus for eye surgery may comprise a nozzle having a delivery lumen, an implant bay coupled to the nozzle, an implant disposed in the implant bay, and an actuator coupled to the implant bay. The actuator may comprise a housing; a bore through the housing; a plunger disposed within the bore; and a compression ring. The plunger can be configured to advance within the bore, thereby advancing the implant from the implant bay through the delivery lumen, and the bore can be configured to compress the compression ring as the plunger moves through the bore. In some embodiments, the bore can be configured to increase compression on the compression ring as the first end of the plunger moves through the bore.

Abstract: An apparatus for eye surgery comprising a housing comprising a key track, a bore through the housing, a plunger at least partially disposed in the bore, and a plunger key. The plunger may comprise a rail and a keyway, and the plunger key may comprise a key guide coupled to the key track, an arm coupled to the key guide, and a rail slot through the arm. The arm may be disposed through the keyway of the plunger to allow the arm to move along the key track from a first position to a second position. The arm may be configured to block the rail in the first position and to align the rail slot with the rail in the second position so that the rail can move through the rail slot.

Abstract: A surgical cutting blade for cutting bone material when the blade is coupled to a hand-held surgical saw includes a distal portion comprising a plurality of cutting teeth, a shank portion adjacent the distal portion, and a proximal portion adjacent the shank portion. The proximal portion may include a longitudinally extending slot having a proximal opening. The slot may be shaped to receive a portion of the surgical saw through the proximal opening. The proximal portion may have a plurality of deflectable fingers respectively separated from a plurality of main body portions by respective gaps. The plurality of deflectable fingers may extend adjacent the longitudinally extending slot, and may deflect into the gaps to increase and decrease a width of a portion of the slot.

Abstract: A surgical system for cutting tissue of a patient includes an outer housing and a reciprocating assembly structurally configured to carry a cutting tool in a reciprocating motion. An actuator knob is manually accessible to the user and may be fixed axially to the outer housing. The reciprocating assembly may reciprocate relative to the actuator knob. The actuator knob may be configured for rotational movement between a lock position and an unlock position. The system may also include a locking mechanism configured to retain a cutting tool within the reciprocating assembly. The locking mechanism may be responsive to movement of the actuator knob to maintain the tool within the output shaft when the actuator knob is in the lock position and permit removal of the tool when the actuator knob is in the unlock position. Surgical cutting tools, such as blades include thickness enhancing features.
