The first and second arms may have an arc shape such that a distal tip of each first and second arm are configured to close as the first and second arms are actuated to a constrained closed position. A catheter may include a locating element at a distal end of a flexible tube. The locating element may be configured for locating the grasping system.

According to exemplary embodiments of the present disclosure, devices, systems, and methods for pyloric occlusion in an endoscopic procedure may include a first flange and a second flange connected to the first flange by a saddle region having a lumen. The second flange may be proximal to the first flange. The pyloric occlusion device may further include a closure element. The closure element may be configured to occlude a flow of material through the lumen, including across the pylorus when deployed. The closure element may be a closure of the lumen by rotation of one of the first or second flanges about the saddle region relative to the other of the first or second flange.

An atraumatic microsurgical forceps may include an actuation structure, an actuation sleeve having an actuation sleeve distal end and an actuation sleeve proximal end, a surgical blank, and atraumatic forceps jaws of the surgical blank having atraumatic forceps jaws distal ends and atraumatic forceps jaws proximal ends. The surgical blank may be disposed within the actuation sleeve wherein at least a portion of the atraumatic forceps jaws extends from the actuation sleeve distal end. A compression of the actuation structure may be configured to gradually extend the actuation sleeve over the atraumatic forceps jaws proximal ends. 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.

An ophthalmic instrument includes a shaft comprising a lumen. The instrument also includes a first arm extending from the lumen, the first arm having a first distal portion having a first flat tip. The instrument also includes a second arm extending from the lumen, the second arm having a second distal portion having a second flat tip that is positioned such that the second flat tip contacts the first flat tip when the first arm is forced towards the second arm. The first arm and the second arm comprise at least in part, a first material that is substantially transparent to electromagnetic radiation having a wavelength within a range of about 700-1200 nanometers (nm) and is substantially opaque to electromagnetic radiation having a wavelength within a range of about 400-700 nm.

A surgical instrument is disclosed herein. The surgical instrument comprises a housing, a first actuation member, a second actuation member, and a first cannula. The first actuation member is configured for imparting a reciprocating action to a portion of the instrument. The second actuation member configured for imparting a rotational action to a portion of the instrument. The first cannula is operatively connected to the second actuation member, such that the first cannula is configured for rotational movement with respect to the housing. In one arrangement, a wire member is disposed within the first cannula and is configured to rotate with the first cannula.

A surgical kit for the repair of a nail bed includes implantable nail plate guides adapted to guide the regrowth of a fingernail over a nail bed, drapes, a suture needle with absorbable suture, a suture needle with non-absorbable suture, wound dressings, and all instruments required to perform the procedure. The instruments preferably include an elevator, a needle driver, a clamp, a tweezers, and a scissors. The kit also includes anesthesia, a syringe, and needles for loading and then administering the anesthesia to the finger. The kit may include a tourniquet, antiseptic, and an antiinfective. Therefore, the kit assembles together several nail plate guides, the instruments for implanting a selected one of the nail plate guides onto the nail bed over a patient, the pre-implantation surgical preparation materials, and the post-implantation wound care materials.

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.

A surgical instrument handle operates a microsurgical instrument on a surgical instrument head by manipulation of the instrument handle. The instrument handle has an elongate center rod with a ring mounted on the rod for reciprocating movement. The ring is operatively associated with the surgical instrument head for operation of the microsurgical instrument of the head. A plurality of resilient arms extend along the length of the rod and engage against a sliding surface of the ring. The inward and outward movement of the plurality of arms reciprocates the ring on the handle rod to cause operation of the surgical instrument head.

A surgical or endoscopic instrument is provided with at least one longitudinal member (28, 30; 128; 228, 230; 328) having a longitudinal extension between a first end and a second end, and a support piece (50, 52; 150, 152; 250, 252; 350, 352; 410; 412; 414; 416), which has at least one structured contact section (60, 62; 160, 162; 260, 262; 360, 362; 420; 422; 424; 426) provided with toothing or corrugation, wherein the at least one structured contact section (60, 62; 160, 162; 260, 262; 360, 362; 420; 422; 424; 426) is integrated in the support piece (50, 52; 150, 152; 250, 252; 350, 352; 410; 412; 414; 416), wherein the support piece (50, 52; 150, 152; 250, 252; 350, 352; 410; 412; 414; 416) and the at least one structured contact section (60, 62; 160, 162; 260, 262; 360, 362; 420; 422; 424; 426) consist of a corrosion-resistant steel material, particularly a stainless steel, and wherein the at least one structured contact section (60, 62; 160, 162; 260, 262; 360, 362; 420; 422; 424; 426) is low-temperature diffusion hardened in a near-surface manner. Furthermore, the disclosure relates to a method for producing a surgical or endoscopic instrument.

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.
