    摘要: 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.

    摘要: Embodiments disclosed herein provide devices, systems, and methods for reducing intraocular pressure. For example, the disclosed devices, systems, and methods are useful for reducing intraocular pressure resulting from conditions, such as acute glaucoma, on a short-term basis until a definitive surgical procedure is performed. More particularly, valved trocar cannula systems for reducing intraocular pressure resulting from conditions, such as acute glaucoma, pending surgical intervention in an operating room are disclosed. In practice, a trocar assembly is used to place a valved cannula assembly in a patient's eye, such as in the anterior chamber or pars plana, to reduce high intraocular pressure. The valved cannula is then left in the patient's eye for a period of time to continuously allow aqueous humor or liquid vitreous humor to flow therethrough, until the patient may be surgically treated in an operating room.

    摘要: An ocular implant delivery system is provided with a number of features. In some embodiments, the delivery system comprises a rotation mechanism configured to rotate and orient a cannula of the system, and an advancement mechanism configured to advance and retract an ocular implant through the delivery system and into an eye of a patient. In some embodiments, the cannula is sized and configured to be inserted into Schlemm's canal of the eye. The ocular implant is configured to maintain its orientation within the delivery system as the cannula is rotated. In some embodiments, the ocular implant automatically disengages the delivery system when it is advanced beyond a distal tip of the delivery system. Methods of implanting an ocular implant are also provided.

    摘要: A tracking system for quantifying retinal traction on a retina of a patient eye includes an indicator device, a stereo camera, and an electronic control unit (ECU). The stereo camera collects and outputs stereo image data. The ECU, which is in communication with the indicator device, executes a method by receiving the stereo image data from the stereo camera during an ophthalmic procedure and thereafter assigning tracking points as coinciding pixels within stereo image pairs. The ECU also automatically performs a digital image correlation (DIC) process using the stereo image pairs to ascertain relative motion of the tracking points, and associates relative motion of the tracking points with the retinal traction using a traction map. A numeric traction quotient is generated that is indicative of magnitude of retinal traction. The ECU executes a control action using the indicator device based on the numeric traction quotient.

    摘要: An ophthalmic surgical instrument for delaminating a retinal membrane includes a handpiece and an actuator mounted on the handpiece. An outer tube has a proximal end mounted to the handpiece. A dissection spatula is extendable outwardly relative to a distal end of the outer tube responsive to movement of the actuator, the dissection spatula defining a channel connected to an opening proximate a distal edge of the dissection spatula. A dispensing system is in fluid communication with the channel. The dispensing system may include a reservoir within the handpiece. The fluid may be dyed blue to enhance visibility of a delaminated portion of the retinal membrane.

    摘要: An ophthalmic surgical instrument for peeling a retinal membrane includes a handle and an actuator mounted on the handle. A first arm and a second arm extend outwardly from a distal end of an outer tube mounted to the handle. The first arm includes a first pulling surface and a first gripping surface and the second arm includes a second pulling surface and a second gripping surface. The pulling surface of each arm is substantially perpendicular to the gripping surface of each arm and the gripping surfaces of the arms face one another. The first pulling surface and the second pulling surface move toward one another when the outer tube is extended over the first arm and the second arm in order to raise a flap of the retinal membrane that is then gripped between the first gripping surface and the second gripping surface.
