  • Patent number: 11849936
    Abstract: The present disclosure relates to devices, systems and methods for endoscopic suturing or stitching through an access tube or the like. An endoscopic stitching device is provided and includes a handle assembly; an elongate shaft supported by and extending from the handle assembly; and an end effector supported on a distal end of the elongate shaft. The end effector includes a neck assembly configured and adapted for articulation in one direction between a substantially linear configuration and an off-axis configuration, and a pair of juxtaposed jaws pivotally associated with one another. Each jaw defines a suture needle receiving recess formed in a tissue contacting surface thereof.

  • Patent number: 11291443
    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.

  • Patent number: 10426516
    Abstract: A seal assembly is provided for reception of an elongated surgical instrument, which comprises a body having at least one opening configured and dimensioned to permit entry of an elongated surgical instrument and defining a central longitudinal axis; a seal member formed of a resilient material and defining an aperture therein, the aperture being configured and dimensioned such that insertion of the surgical instrument into the aperture causes the resilient material defining the aperture to resiliently contact the outer surface of the surgical instrument in a substantially fluid tight manner, the seal member further including a peripheral flange element which contacts a surface of the body to form a contact seal therewith; and a fabric layer juxtaposed relative to the resilient material. The seal assembly may further include a coating applied to the seal member to reduce friction between the seal member and surgical instrumentation inserted therein.

  • Patent number: 9883880
    Abstract: An articulation mechanism for a surgical instrument includes an articulation assembly, a plurality of cables, and a trigger. The cables are coupled to the articulation assembly at a proximal end thereof and extend distally therefrom. The cables are configured to engage an end effector assembly of the surgical instrument at a distal end thereof. The trigger is coupled to the articulation assembly and is selectively moveable from a shipping position to a use position. In the shipping position, the cables are substantially un-tensioned. In the use position, the cables are disposed in an initial tensioned position. In the use position, the trigger is moveable between an unlocked position and a locked position. In the unlocked position, the cables are selectively tensionable to articulate the end effector assembly. In the locked position, the tensions on the cables are maintained to lock the end effector assembly in position.
