Abstract: The present disclosure generally relates to devices for ophthalmic procedures, and more particularly, to apparatus for performing subretinal injections and methods of use thereof. In some embodiments, a surgical instrument for fluid injection may include a handpiece configured for grasping by a user, the handpiece comprising: a first lumen disposed therein; and an actuatable toggle movably coupled with the handle. The cannula may be coupled to the handpiece and configured to be introduced into an eye. The cannula may include a second lumen extending therethrough and a needle movably disposed within the second lumen and coupled with the actuatable toggle. The needle may be configured to extend from and retract into the second lumen at a distal end of the cannula upon actuation of the toggle.

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: Certain embodiments provide a surgical instrument comprising surgical instrument comprising an device having a functional end and a main handle comprising a distal end coupled to the device. The surgical instrument further comprises an actuation handle insert comprising a number of first rolling components and an actuation tube coupled to the actuation handle insert, wherein the functional end of the device at least partially extends outside of the actuation tube when the device is deactivated. The surgical instrument further comprises levers comprising second rolling components. The surgical instrument further comprises a plurality of rolling elements, wherein each of the rolling elements is placed between one of the second rolling components and one of the first rolling components and pressing one or more of the levers pushes the actuation handle insert forward relative to the device, causing the actuation tube to transition the device from the 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.

Abstract: Certain aspects of the present disclosure provide a low friction trocar valve comprising a set of sheets arranged circularly and defining an entry point for the insertion of an instrument. In certain aspects, each sheet of the trocar valve's set of sheets comprises areas that overlap with two adjacent sheets. The trocar valve is formed in an opening of a valve housing coupled to or formed as part of a trocar cannula to provide a sealing mechanism for preventing the escape of pressurized fluids from the trocar cannula.
