Abstract: The present disclosure relates to trocar-cannula insertion tools for ophthalmic procedures. In certain embodiments, a cap for a trocar-cannula insertion tool includes a body having a proximal end and a distal end opposite the proximal end. A marking element extends in a distal direction from the distal end of the body and includes at least one marking tip for forming one or more indentations on a patient's eye during an ophthalmic procedure. A manipulation element extends from the body in a direction different from the marking element and includes at least one manipulation tip for gripping a tissue of the patient's eye during the ophthalmic procedure. In certain embodiments, the cap further includes at least one window for exposing a photoluminescent cannula of the trocar-cannula insertion tool to light, enabling the cannula to absorb photons prior to insertion thereof.

Abstract: A vitrectomy probe with a light emitting, visibly discrete traceable probe cap. The light emitting, visibly discrete character of the probe cap may aid a surgeon in tracing the end of a needle of the vitrectomy during a vitrectomy procedure. The probe cap may be of a biocompatible polymer accommodating phosphorescent pigment or of another suitable light source.

Abstract: Embodiments disclosed herein provide devices, systems, and methods for instrument exchanges during ophthalmic surgery. More particularly, the present disclosure relates to valved cannula assemblies and methods of use thereof. A valved cannula assembly includes a cannula having a head at a proximal end of the cannula and a hollow rod extending from the head to a distal end of the cannula. The valved cannula assembly includes a valved hub coupled to the head and including a septum having two or more curved flaps configured to provide an opening for an instrument.

Abstract: The present disclosure generally relates to surgical instruments having variable stiffness, and more particularly, surgical instruments having variable stiffness for ophthalmic surgical procedures. In certain embodiments, a surgical instrument includes a base unit, a probe, a stiffener, and an actuation mechanism. The stiffener is formed of a hollow tubular member substantially surrounding at least a portion of a length of the probe. The actuation mechanism is configured to actuate the stiffener along the length of the probe and adjust the stiffness of the probe, thus providing a user better control of the surgical instrument. The actuation mechanism includes a stiffener biasing device configured to apply a first biasing force against the stiffener in the distal direction and, in some embodiments, a control member configured to lock the stiffener in a position along the length of the probe.

Abstract: A platform configured to secure a service loop of tubing from a fixed position surgical device. The platform allows for avoidance of taping and re-taping of service loops. Additionally, the platform provides stability to the surgical device so as to avoid unintentional changing of position or orientation of the device. This is of particular benefit for an infusion port during eye surgery and other similar devices where orientation of the installed device aids device performance.

Abstract: Devices and methods are disclosed for improved irrigation sleeves for ophthalmic instruments to prevent or reduce the likelihood of the irrigation sleeve twisting and/or buckling upon inserting the irrigation sleeve into the eye. In some embodiments, an irrigation sleeve comprises a side opening for irrigation having an elongated shape, wherein the elongated shape is longer in a direction parallel to the longitudinal axis of the distal tube of the irrigation sleeve than in a direction around a circumference of the distal tube of the irrigation sleeve. In some embodiments, an irrigation sleeve comprises at least one rib on an internal surface of the distal end of the irrigation sleeve. In some embodiments, the irrigation sleeve has been subjected to one or more manufacturing steps adapted to stiffen the irrigation sleeve, such as being coated with a stiffening coating or being treated by being exposed to gamma irradiation.
