    Abstract: Embodiments of a surgical instrument including an actuation lockout system as well as its method of use are disclosed. In one embodiment, a surgical instrument includes a trigger and a driveshaft coupled to the trigger such that actuation of the trigger causes the driveshaft to move from a first position to a second position, thereby resulting in deployment of a surgical fastener. An actuation lockout system restrains distal movement of the driveshaft until a force greater than or equal to a threshold force is applied to the trigger.

  • Patent number: 10772632
    Abstract: A surgical stapling device is described having a tool assembly including an anvil assembly and a staple cartridge having a series of tri-staples which are supported and configured to be rotatably ejected from the staple cartridge into the anvil assembly to suture tissue. The manner in which the staples are supported and ejected from within the staple cartridge facilitates the use of a tool assembly of reduced diameter that includes staples capable of suturing thicker tissues than would normally be associated with tool assemblies with such a reduced diameter. A tri-staple is also described that can be ejected from the surgical stapling device. In embodiments, the tri-staple includes three legs of different lengths. Each of the legs is configured to provide a different degree of compression when applied to tissue. In addition, each of the staple legs has a D-shaped configuration when deformed.

  • Patent number: 10702277
    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.

    Abstract: A surgical stapling device includes a housing and a plurality of cartridges that are coupled together to form a barrel that is rotatably supported within the housing. Each of the cartridges defines a plurality of staple pockets, each supporting a staple. An anvil is coupled to the housing and is movable in relation to the barrel between an open position and a clamped position. A guide shaft extends through the housing and through the barrel. The guide shaft supports a sled and a clamping member. The sled is configured to translate through the barrel to eject the staples from an active cartridge of the plurality of cartridges in response to actuation of a push rod. After firing staples from the active cartridge, the sled and the guide shaft are configured to index or rotate the barrel within the housing to move a second cartridge of the plurality of cartridges to the active position upon retraction and subsequent movement of the sled through a second firing stroke.

  • Patent number: 10159481
    Abstract: A method and device for controlling the compression of tissue include clamping tissue between a first clamping member and a second clamping member by driving at least one of the clamping members with an electric motor toward a predetermined tissue gap between the clamping members and, during the clamping, monitoring a parameter of the electric motor indicative of a clamping force exerted to the tissue by the clamping members. The method and device include, during the clamping, controlling the electric motor, based on the monitored parameter, to limit the clamping force to a predetermined maximum limit.

  • Patent number: 9987005
    Abstract: A surgical apparatus has a clamp and a stapling mechanism. The clamp has a first jaw and a second jaw to clamp on a body tissue at a desired location for a stapling operation. The stapling mechanism is controlled by a trigger handle or a switch assembly. The surgical apparatus has a controller for providing a delay between clamping and actuating of the firing mechanism of the stapling mechanism. The delay provides for a desired amount of time for tissue compression producing a more uniform staple formation. The surgical apparatus also has an indicator. The indicator provides feedback about the status of the stapling mechanism and also displays a time of tissue compression by the clamp.
