    Abstract: A surgical clip for a clip applier to ligate vessels. The clip contains two opposing legs connected in parallel by an apex to form a U-shape. Each leg has an outer surface with a half-round cross-sectional configuration for minimizing tissue damage by preventing clip scissoring during ligation. Each leg has an inner surface with a flat central surface, two concave grooves on opposing sides of the central surface, and two convex ridges on opposing sides of the each groove. As a vessel is ligated, vessel tissue moves into the concave grooves while remaining frictionally engaged by the compressive forces applied by the central surfaces and convex ridges of each leg so that the clip does not move on the vessel. The edges of the grooves and the edges of the ridges of each leg are rounded to prevent any cutting of the ligated vessel.

  • Patent number: 10687804
    Abstract: An applicator instrument for dispensing surgical fasteners includes a housing, an elongated shaft, and an elongated conduit extending through the elongated shaft. A firing system is disposed within the housing. The firing system has an insertion tool having a top surface that extends proximal and distal ends thereof and a stripper ramp that projects above the top surface. An actuator activates the firing system to commence a firing cycle. During the firing cycle, the firing system drives the insertion tool toward the distal end of the elongated shaft. The elongated conduit has a top wall with a top notch formed therein. The stripper ramp slides through the top notch for guiding movement of the insertion tool as the firing system drives the insertion tool toward the distal end of the elongated shaft.

  • Patent number: 10639045
    Abstract: A surgical clip applier and methods for applying surgical clips to a vessel, duct, shunt, etc., during a surgical procedure are provided. In one exemplary embodiment, a surgical clip applier is provided having a housing with a trigger movably coupled thereto and a shaft extending therefrom with opposed jaws formed on a distal end thereof. The trigger is adapted to advance a clip to position the clip between the jaws, and to move the jaws from an open position to a closed position to crimp the clip positioned therebetween. The surgical clip applier can include a variety of features to facilitate use of the device, including features to align a clip with the jaws, features to prevent unintentional migration of a clip, and features to prevent clip fallout during formation.

  • Patent number: 10624630
    Abstract: A multiple-fire securing device includes a hollow outer shaft, a reloader, a reloader movement assembly, a rail, and securing structures each defining an inner securing orifice. The reloader longitudinally moves within the outer shaft and has a distal end shaped to temporarily contact one of the securing structures. The rail is disposed within the reloader and has an installing location. The securing structures are disposed on the rail. The reloader movement assembly moves the reloader longitudinally in a distal direction to deliver a first securing structure to the installing location from a first proximal position and moves the reloader proximally away from the installing location without the first securing structure to a position in which the distal end of the reloader temporarily contacts a second one of the securing structures. The second and successive securing structures are moved one at a time to the installing location.

  • Patent number: 10610223
    Abstract: A surgical instrument with a stowing knife blade includes an elongated shaft, an end effector coupled to the shaft and including two opposed jaws, a housing included in one of the jaws, a first member mounted in the housing and movable distally, a knife pivotally coupled with the first member, and a second member. The knife is configured to cut when advanced distally. The first and second members are moved distally at the same rate during a cutting motion of the knife and the second member blocks a rotation of the knife relative to the first member during the cutting motion of the knife. After moving through the first distance, relative movement between the first and second members occurs so as to permit or induce the previously blocked rotation of the knife so that the knife can be stowed.

  • Patent number: 10588634
    Abstract: An exemplary surgical method includes possessing a loader that holds a curved-tip cartridge, and a surgical stapler that includes an anvil and channel at a distal end thereof; causing at least one of the loader and the channel to move toward the other; as a result of the causing, engaging the loader and the curved-tip cartridge with the channel; and causing at least one of the loader and the channel to move away from the other, such that the curved-tip cartridge remains engaged with the channel. That method further may include actuating the surgical stapler; grasping the unloader; sliding the unloader toward the channel; disengaging the curved-tip cartridge from the channel with the unloader; and withdrawing the unloader away from said channel, wherein the withdrawing causes the curved-tip cartridge to disengage from the channel.

    Abstract: A medical shaft-type instrument includes an instrument head for applying clamps, the instrument head connectable via an instrument shaft to an instrument handle for actuating the instrument head. The instrument also includes a clip magazine having a housing, in which magazine a plurality of clamps are bunkered at a predetermined storage position spacing to each other according to the storage principle. All of the clamps can be moved forward by one storage position by a reciprocating transport and entraining rail within the scope of a single delivery stroke. The transport and entraining rail has one clamp entraining element per clamp. The relative distance of the individual clamp entraining elements differs from the respective storage position distances of the clamps in such a way that the entrainment of the bunkered clamps is carried out within the scope of one single delivery stroke in a clocked way.
