Abstract: A trocar-cannula insertion tool for ophthalmic procedures may include a cap with 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. The cap may further include 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: An ultrasonic handpiece includes a piezoelectric element assembly. Control signals drive the piezoelectric element assembly simultaneously in a first mode of oscillation and a second mode of oscillation. Feedback of a resulting oscillation of the piezoelectric element assembly in the first mode and the second mode is generated. Based on the feedback, the frequency of each of the first mode and second mode is independently adjusted, as needed, so that the resulting oscillation of each of the first mode and the second mode is each approximately at its respective resonant frequency.

Abstract: Certain embodiments herein disclose a cannula assembly. The cannula assembly comprises a cannula, having a proximal end and a distal end. The cannula comprises a head at the proximal end, the head having one or more wings. The cannula also comprises a hollow rod extending from the head to the distal end. The cannula assembly also comprises a hub couplable to the head and having a housing with an inner wall. The inner wall comprises an undercut, and one or more distal ends of the corresponding one or more wings are configured to fit into the undercut and couple the hub to the head upon insertion of the head into the hub.

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.

Abstract: The present disclosure generally relates to microsurgical instruments having variable stiffness such as microsurgical instruments having variable stiffness for ophthalmic surgical procedures. In one embodiment, a surgical instrument includes a probe and a stiffener assembly. The stiffener assembly further includes a stiffener formed of a hollow tubular member substantially surrounding at least a portion of a length of the probe. Actuation of the stiffener along the length of the probe adjusts the stiffness of the probe, thus providing a user better control of the surgical instrument.

Abstract: Embodiments disclosed herein relate to an infusion cannula for infusion/venting of fluids to/from the eye to control intraocular pressure. The infusion cannula includes a tubular body with a tubular inlet located at a proximal end of the tubular body and a tubular outlet located at a distal end of the tubular body. The tubular outlet is aligned with a first longitudinal axis and configured to extend through a septum of a valved cannula hub. The infusion cannula includes a retention piece extending from or coupled to the tubular body. The retention piece has an annular body surrounding the tubular body at the distal end of the tubular body and configured to be coupled to the valved cannula hub. An inner surface of the annular body has a profile configured to form a snap fit with an overhang formed along an outer surface of the valved cannula hub.

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.
