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 rotational cutter for delaminating a membrane from a retina of an eye. The rotational cutter may comprise a first shaft and a second shaft comprising a blade portion, wherein the second shaft is coupled to a driver that is configured to at least partially rotate the second shaft relative to the first shaft, wherein rotating the second shaft rotates the blade portion for delaminating the membrane. The rotational cutter may also comprise a bottom portion configured to interface with a surface of the retina, wherein the bottom portion comprises one or more curved edges.

Abstract: Certain aspects of the present disclosure provide a low friction trocar valve (100) comprising a set of sheets (120) arranged circularly and defining an entry point (125) for the insertion of an instrument. In certain aspects, each sheet (120) of the trocar valve's set of sheets (120) comprises areas (122) that overlap with two adjacent sheets (120). 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.

Abstract: In certain embodiments, an apparatus is provided for performing a subretinal injection into a subretinal space between a retina and a retinal pigment epithelium of an eye. The apparatus includes an injection needle (110) having a proximal end (112) and a distal end (114), the distal end (114) configured to be insertable into the subretinal space at a position on a surface of the retina. The apparatus includes a multi-lumen tubing (120) having a distal end (122) coupled to the proximal end (112) of the injection needle (110) and a proximal end coupled to a fluid control unit. The apparatus includes a stabilizer (130) configured to immobilize the injection needle (110) at the position on the surface of the retina. The fluid control unit has a plurality of fluid reservoirs containing a non- treatment solution, a treatment solution, and a working fluid which are injectable into the eye via separate lumens (128a, 128b, 128c) of the multi-lumen tubing (120).
