A plating processing method of a gripping surface of a gripping tool includes: temporarily and evenly fixing a plurality of first diamond grains having a uniform first grain diameter; adhering the first diamond grains by depositing a metal containing nickel on a gripping surface in a uniform thickness after the first diamond grains have been temporarily fixed; placing a plurality of second diamond grains having a second grain diameter on a metal surface of the gripping surface on which first diamond grains are not present; and adhering the second diamond grains by further depositing a metal containing nickel within a second plating solution on the metal surface in a uniform thickness that does not exceed the first diameter grain and the second diameter grain until a position relationship between the metal surface and the second diamond grains is not displaced even when the gripping tool is moved.

A membrane removing instrument comprising a surgical blank having a surgical blank distal end and a surgical blank proximal end, the surgical blank configured for being at least partially disposed in a hypodermic tube wherein the surgical blank has dimensions configured for performing ophthalmic surgical procedures, and at least one micro-pick proximate to the surgical blank distal end, the micro-pick being configured to engage and incise an ophthalmic membrane and form a membrane flap.

A medical grasping device is disclosed. The medical grasping device may be configured to retrieve an object from within a body lumen. A medical grasping device assembly, wherein a portion of the medical grasping device is disposed within a lumen of a delivery sheath, and methods of using the medical grasping device assembly are also disclosed.

Membrane forceps for performing an ILM or ERM peel procedure include a handle, a tube extending from the handle, and forceps jaws extending from the tube. The forceps jaws may be configured to grasp an ILM or ERM, and may include an outer surface having a roughened surface. The roughened surface may be structurally configured to aid in gaining an edge of the ILM or ERM.

A retrieval device may include a sheath including a distal end and a proximal end, and an end effector at the distal end. At least a portion of the end effector may be movable relative to the sheath between extended and retracted states. The end effector may include a support member extending from the distal end of the sheath, and a movable member extending from the distal end of the support member. The device may include a handle assembly at the proximal end of the sheath, having an actuation member for transitioning the end effector between the extended and retracted states. The device may include a biasing member coupled to at least one of the actuation member and the sheath that may control a force, exerted by one of the movable members and the support member on the other, generated by relative movement between the movable and support members.

A membrane aggregating forceps may include a blank, a membrane aggregating forceps tip of the blank, a hypodermic tube, and an actuation structure. The blank may be disposed in the hypodermic tube and the actuation structure wherein a compression of the actuation structure is configured to close the membrane aggregating forceps tip and wherein a decompression of the actuation structure is configured to open the membrane aggregating forceps tip. The membrane aggregating forceps tip may include a first membrane aggregating forceps jaw having a first curved medial projection and a second membrane aggregating forceps jaw having a second curved medial projection. The first curved medial projection may include a first membrane socket, a first membrane aggregating fillet, and a first blunt edge. The second curved medial projection may include a second membrane socket, a second membrane aggregating filled, and a second blunt edge.

An assembled blank may include a blank tip attached to a blank base, e.g., the blank tip may be welded to the blank base. The blank tip may be manufactured by modifying flat stock, e.g., tiers of blank tips may be manufactured by modifying tiers of flat stock. The blank tip may comprise a first forceps jaw, a second forceps jaw, and a blank tip aperture. The assembled blank may be disposed within a hypodermic tube and an actuation structure of a microsurgical instrument.

A surgical instrument may have a handle, a support sleeve, and an inner sleeve. Illustratively, the support sleeve may be configured to actuate relative to the inner sleeve to protect the inner sleeve before and after a surgical procedure and to expose a portion of the inner sleeve during the surgical procedure. In one or more embodiments, an application of a force to a distal end of the support sleeve may be configured to retract the support sleeve relative to the inner sleeve. Illustratively, a reduction of a force applied to the distal end of the support sleeve may be configured to extend the support sleeve relative to the inner sleeve.

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.

Disclosed are systems, devices, and methods that allow a surgeon to both cut an implanted microsurgical device and also to simultaneously retain the cut-off piece using a single tool and a single motion. In various embodiments, this is achieved by a microsurgical cutting and grasping instrument that may include a piston assembly including a piston, a cap, an outer shell housing the piston and a tension member in operative engagement with the piston and the cap, a cannula connected to the piston, a rod axially disposed in the cannula which is moved in an axial direction by the piston when the outer shell and the piston are squeezed together, a cutter assembly disposed at a distal end of the rod and configured to perform both an inline cutting action and a grasping action on a target.
