An extension of the actuation sleeve over the atraumatic forceps jaws proximal ends may be configured to gradually close the atraumatic forceps jaws wherein the atraumatic forceps jaws initially contact at the atraumatic forceps jaws distal ends.

A micro needle holder capable of cutting sutures, configured for holding needles and cutting sutures during microsurgeries, includes a needle holding unit and a suture cutting unit. The needle holding unit includes a pair of first plier bodies and a first shaft, where each of the first plier bodies has a needle holding end, a first shaft connecting part, and a first plier arm. The suture cutting unit includes a pair of second plier bodies and a second shaft, where each of the second plier bodies includes a suture cutting end, a second shaft connecting part, and a second plier arm. Moreover, the first plier arms are respectively connected with the second plier arms and are configured to elastically open and close corporately.

Surgical apparatus for performing in pars plana vitrectomy microsurgery including a cannula having an intraocular portion that connects to an infusion tube. The intraocular portion includes fenestrations at its distal end. The intraocular portion receives fluid through the infusion tube and dispenses the fluid through the fenestrations lessening the flow at an infusion site in an eye. The surgical apparatus includes a vitreous cutter having a suction tube at one end and a shaft at another end. The cutting port cuts vitreous into smaller pieces or a laser that liquefies the vitreous. The shaft receives the cut vitreous pieces and the suction tube draws out the cut vitreous pieces from the eye. The surgical apparatus includes a vitreoretinal surgical tool having a vitreoretinal cutter having a scissor-like or forceps-like mechanism. The vitreoretinal cutter holds and/or cuts a membrane in the eye during the microsurgery.

A medical device for joining materials is provided. The device comprises a piercing element configured to penetrate materials to be joined. The piercing element is sufficiently sharp to penetrate materials to be joined and comprises a hollow interior along at least a portion of its length configured to distal advancement of a fastener therethrough; and an open tip through which the fastener can be pushed. The device can be used for fastening materials including tissue, synthetic mesh, and biologic mesh (e.g., ADM).

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.

Embodiments of the present disclosure generally relate to microsurgical cutting devices for ophthalmic procedures. In certain embodiments, a cutting tool assembly includes a first blade in a fixed position and a second blade configured to move relative to the first blade to perform a cutting motion. The first blade includes a first longitudinal body portion and a first end portion extending laterally from the first body portion. A distal surface of the first end portion has a bowed morphology to match a curvature of a retinal surface and is further coated with a first coating to reduce damage to ocular tissues during use. The second blade includes a second longitudinal body portion and a second end portion extending laterally from the second body portion. A distal surface of the second end portion includes a cutting edge for cutting tissues, while a proximal surface thereof is coated with a second coating.

Devices, systems, and methods described herein relate to affecting an internal diameter of a body lumen, and, in many examples, of a pylorus. A silk-based bulking agent may be injected in a pyloric tissue so as to reduce an effective inner diameter of the pylorus. A multi-part occluding agent may be injected into a pylorus on the surface of the pyloric tissue to occlude the pylorus alone or in combination with the silk-based bulking agent.

Particular embodiments disclosed herein provide a surgical instrument comprising a device having a proximal end and a functional end configured to be inserted into a body part, an assembly having a proximal end and a distal end, a shaft coupled to the proximal end of the assembly, the shaft having a shaft housing, a bearing positioned around the assembly, wherein the bearing is configured to slide over the assembly, a hub having a sleeve tube. The basket comprises a plurality of grooved levers, each grooved lever having a proximal end received by the shaft housing and a distal end coupled to a tip of the basket, wherein compressing one or more of the plurality of grooved levers moves the bearing and the hub relative to the shaft and toward the functional end of the device, causing the sleeve tube to transition the device from the deactivated state to an activated state.

One or more control wires may be housed in a lumen and actuated using a articulation control of a handle assembly.

A surgical instrument, and methods for its use, is described that includes clamp heads that can be nestled within or extended from a tubular sheath by longitudinal movement of the clamp heads' tines with respect to the tubular sheath. One of the tines includes an arch that slides against a mouth and inside wall of the tubular sheath, causing the clamp heads to open or close. The clamp heads close lightly, to within a predetermined (or zero) distance from one another, gently grasp an ultrathin polymer substrate seeded with cells, and pulls it within the sheath such that the substrate curls and folds to protect the cells.
