An apparatus for delivering an implant to an eye using a ratchet drive. Some embodiments of an apparatus for delivering an implant to an eye may comprise a gear rack configured to be coupled to the implant, a forward gearwheel, an input gearwheel meshed with the forward gearwheel, an idler gearwheel meshed with the input gearwheel, and a reverse gearwheel meshed with the idler gearwheel. An actuation lever may be configured to rotate the input gearwheel. 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.

Ratchet drive delivery for surgical implants

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.

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.

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.
