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.

Abstract: An apparatus disclosed herein may include a housing, an injection line sub-assembly coupled to a distal end of the housing, a fluid selector coupled to the housing and movable between a first position and a second position, a drug container coupled to the housing and disposed between the fluid selector and the sub-assembly, and a drug container bypass line coupled to the housing and disposed between the fluid selector and the sub-assembly. When the fluid selector is in the first position, a first outlet of the fluid selector is in fluid communication with the drug container bypass line for injecting a fluid through the drug container bypass line and into the sub-assembly. When the fluid selector is in the second position, a second outlet of the fluid selector is in fluid communication with the drug container for injecting a drug from the drug container into the sub-assembly.

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.
