Abstract: A surgical instrument includes a flexible outer grasping member and a flexible inner grasping member for peeling a membrane from the retina of a patient's eye. The surgical instrument includes a handle and at least one actuator. An outer tube has a proximal end mounted to the handle. The outer and inner grasping members extend outwardly from a distal end of the outer tube, or are configured to extend outwardly from the distal end of the outer tube. The at least one actuator may be used to move at least one of the outer grasping member and the inner grasping member relative to the other such that the inner grasping member and the outer grasping member are brought together to grasp the retinal membrane.

Abstract: 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 grasping structure is extendable outwardly relative to a distal end of the outer tube responsive to movement of the actuator. The grasping structure includes a cavity having an opening facing the retinal membrane in use. A blade extends along a portion of the opening and a cushion defining a plurality of openings is positioned within the cavity. Vacuum pressure is applied to a channel in the cushion and coupled to the openings in order to grasp the retinal membrane, which may then be peeled from the retina.

Abstract: 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.

Abstract: An ophthalmic surgical instrument for peeling a retinal membrane includes a handle and an actuator mounted on the handle. An outer tube is mounted to the handle and an inner rod extends within the outer tube. A grasping structure is secured to a distal end of the inner rod having first and second polymer arms secured to the inner rod. Each of the first polymer arm and the second polymer arms has a distal end that is angled to conform to the retinal membrane. The actuator is configured to control relative position of the inner rod and the outer tube in order to extend the grasping structure out of the outer tube and withdraw the grasping structure within the outer tube.

Abstract: 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.

Abstract: 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.
