GRASPING STRUCTURE FOR OPHTHALMIC SURGERY
20240197526 · 2024-06-20 ·

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.

Particular embodiments disclosed herein provide a surgical instrument for grasping a retinal membrane. An ophthalmic surgical instrument for peeling a retinal membrane includes a handle having an actuator mounted on the handle. An outer tube has a proximal end mounted to the handle. First and second arms extend outwardly from the outer tube and each have pulling surfaces thereon. The pulling surfaces are configured such that when the outer tube is in first position, the pulling surfaces flare outwardly from one another and may both be placed simultaneously in contact with the retinal membrane. The arms may be made of a flexible material to conform to the retinal membrane. When the outer tube is in a second position, the pulling surfaces are facing one another and pressed against one another. The pulling surfaces may include barbs that point toward the outer tube when the pulling surfaces are drawn together.

DEVICES AND METHODS FOR IMPLANTING CORNEAL TISSUE

A device for manipulating an implant includes a handle coupled to a guide extending from the handle to a distal end. The device includes an engagement mechanism disposed at the distal end of the guide and configured to engage an implant. The device includes a first actuator disposed on the handle and coupled to the engagement mechanism. The first actuator causes the engagement mechanism to engage the implant. The device includes an air chamber disposed in an interior chamber of the handle and configured to hold air. The device includes a lumen coupled to the air chamber and extending along the guide to the distal end. The lumen includes an air channel extending through the lumen. The device includes a second actuator disposed on the handle. The second actuator causes the air chamber to deliver the air, via the air channel, to the distal end.

Articulating microsurgical instrument

An apparatus and method for an articulating microsurgical instrument is disclosed herein. The articulating microsurgical instrument may be configured to be operable with a Doppler probe, bone grasper, soft tissue grasper/dissector, scissors, flexible forceps, or a suction/irrigation line configured to provide tools within a surgical location that can be adjusted to a desired angle of operation. A tip assembly may comprise an articulating portion at a distal tip and the articulating portion may be configured to deflect upon actuation of an articulation control. The articulation control may be a trigger assembly or a roller wheel. A bayonet-style handle may include a set of posts configured to interact with the one or more control wires during actuation of the articulation control. One or more control wires may be housed in a lumen and actuated using a articulation control of a handle assembly.

Microsurgical handle and instrument

A microsurgical handle and instrument may include an actuation structure having an actuation structure distal end and an actuation structure proximal end, a plurality of actuation arms of the actuation structure, and an actuation structure base. A compression of the actuation structure may be configured to extend the actuation structure distal end relative to the actuation structure proximal end. A compression of the actuation structure may be configured to expand an extension joint of an actuation arm of the plurality of the actuation arms. A decompression of the actuation structure may be configured to retract the actuation structure distal end relative to the actuation structure proximal end. A decompression of the actuation structure may be configured to collapse an extension joint of an actuation arm of the plurality of actuation arms.

COMBINATION ELECTROSURGICAL INSTRUMENT
20190142502 · 2019-05-16 ·

An instrument including a first arm, a second arm, and a blade. The first arm includes a lumen in communication with a source of irrigation fluid and one or more outlets in communication with the lumen for delivering the irrigation fluid to a surgical site. The instrument is switchable between a first configuration and a second configuration. In the first configuration, the instrument is configured to deliver a first therapy current through a distal end of the first arm, a distal end of the second arm, or both. In the second configuration, a distal end of the blade extends beyond the distal end of the first arm and beyond the distal end of the second arm.

Microsurgical tool adapters, systems and related methods

An adapter system can include a set of adapters operably adapted to a set of microsurgical tools. Each adapter in the set of adapters can be formed for a complimentary surgical tool in the set of surgical tools. Each adapter can have a setback feature designed to orient a corresponding tool tip at a common tip distance. An adapter receptacle can include a joint or joints having a rotary motion and/or translation mechanism and a setback stop feature.

SURGICAL MULTI-TOOL AND METHOD OF USE
20190083120 · 2019-03-21 ·

Surgical tool are disclosed that include a first tip and a second tip. The first tip and the second tip can have a first configuration, an intermediate configuration, and a second configuration. In the first configuration the tool operates as forceps and in the second configuration the tool operates as scissors. In the intermediate configuration the tool operates as a probe. The tips can be brought together to transition between the first configuration and the intermediate configuration. The tips can be rotated to transition between the intermediate configuration and the second configuration. Method are disclosed that include the step of providing a tool having a first tip extending distally and a second tip extending distally, moving at least one of the first tip and the second tip toward the other of the first tip and the second tip, and rotating the first tip and the second tip.

CELLULAR TRANSPLANT CARRIER DEVICES AND METHODS OF USING THE SAME

A cell transplant carrier including a carrier plate and a carrier housing. The carrier plate includes a body and one or more chambers defined in the body. Each of the one or more chambers is configured to receive a cell transplant and is shaped to cause the cell transplant to be at least partially exposed in order to permit removal of the cell transplant therefrom. The carrier housing includes a carrier plate opening leading to an inner compartment configured to removably receive the carrier plate.

SYSTEMS AND METHODS FOR INCREASED OPERATING ROOM EFFICIENCY
20190053800 · 2019-02-21 ·

Systems, devices and methods to improve safety and efficiency in an operating room comprise providing a suture package that holds new suture needles and needle receptacles for storing used needles. The devices can be safely worn for the surgeon to self-dispense new suture needles in the near surgical field and to secure the used needles into a needle trap or a needle retainer located on his extremity, on his operative instruments or on the surgical drapes. The device may provide automated and/or simplified needle counting both during use and after removal from the surgical field. The device may be configured for ergonomic and efficient use so as to minimize the actions and motions of the surgeon to dispense and secure the needle.
