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

Abstract: A surgical knife for otologic procedures includes a handle comprising a distal end and a proximal end, the handle further comprising a control member and a shaft comprising a distal end and a proximal end, the proximal end coupled to the distal end of the handle. The surgical knife further comprises a rod disposed within the shaft and comprising a distal end and a proximal end, wherein the proximal end of the rod is coupled to the control member, and wherein the rod is configured to rotate about a first rotation axis upon actuation of the control member. The surgical knife further comprises a round blade rotatably coupled to the distal end of the rod and configured to rotate about a second rotation axis, wherein the second rotation axis is disposed at a fixed, non-zero angle relative to the first rotation axis.

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, the apparatus includes an injection needle having a proximal end and a distal end, the distal end configured to be insertable into the subretinal space at a position on a surface of a retina. The apparatus may further include an inserter device removably coupled to the injection needle and a tubing having a distal end coupled to the proximal end of the injection needle and a proximal end coupled to a fluid source. The tubing may have a first lumen and a second lumen, wherein the tubing is disposed through the inserter device. The apparatus may further include a stabilizer configured to immobilize the injection needle at the position on the surface of the retina and a fluid source. The fluid source may include both a first fluid reservoir containing a non-treatment solution and a second fluid reservoir containing a treatment solution. The fluid source may be configured to provide the non-treatment solution from the first fluid reservoir to the subretinal space via the first lumen. The fluid source may be further configured to provide the treatment solution from the second fluid reservoir into the subretinal space via the second lumen.

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, the first lumen configured to receive a fluid cartridge comprising one or more injection fluids and a fluidic drive system disposed within the first lumen, the fluidic drive system for driving a flow of the one or more injection fluids from the fluid cartridge into a cannula. The cannula may be coupled to the handpiece and be configured to be introduced into an eye. The cannula may include a second lumen extending therethrough for receiving the one or more injection fluids flowed from the fluid cartridge and a needle movably disposed within the second lumen, the needle configured to extend from and retract into the second lumen at a distal end of the cannula.

Abstract: The present disclosure generally relates to a trans-eustachian multi-function system. The trans-eustachian multi-function system comprises a body configured for disposition within a eustachian tube, the body comprising a proximal end, a distal end, a transverse cross-sectional shape, a longitudinally-extending length, an outer wall configured for disposition proximate a wall of the eustachian tube, and an inner portion defining a passageway; and a distal anchor disposed proximate the distal end, the distal anchor configured to releasably anchor the body against the wall of the eustachian tube.

Abstract: An otologic instrument includes a handle configured to be held by a hand of a surgeon and a cannula extending outwardly from the handle and mounted to the handle. An articulated tube is at least partially positioned within the cannula and at least partially extends outwardly from a distal end of the cannula. An actuator is configured to articulate the articulated tube relative to the cannula to position a distal end of the suction tube at a plurality of positions within a three-dimensional volume. The actuator may be configured to control extension of the articulated tube relative to the cannula, the articulated tube having a curved shape when undeformed. The actuator may be configured to pull a cable or push a push rod within the articulated tube to adjust the curvature of the articulated tube.

Abstract: A surgical knife for ear surgery includes a handle comprising a control mechanism and a shaft coupled to and extending distally from the distal end of the handle. A rod disposed within the shaft comprising a distal end and a proximal end opposite the distal end, wherein the proximal end of the rod is coupled to the control mechanism and wherein the rod is configured to translate along a longitudinal axis of the shaft upon actuation of the control mechanism. The surgical knife further includes a straight knife coupled to the distal end of the rod, wherein translation of the rod causes the straight knife to extend or retract out of the distal end of the shaft. The surgical knife further includes a round knife attached to the distal end of the shaft.
