  • Publication number: 20140263544
    Abstract: Embodiments of a surgical instrument and its methods of use are disclosed. The disclosed embodiments of a surgical instrument may include a handle and an elongated shaft assembly distally extending from the handle. The elongated shaft assembly may include an articulable portion. An articulation control may be associated with the elongated shaft assembly. The articulation control may be movable between a first position in which the elongated shaft assembly is arranged in a first articulation position and a second position in which the elongated shaft assembly is arranged in a second articulation position. The surgical instrument may include a fastener deployment system with a locking member. The articulation control may block movement of the locking member when the articulation control is located in the first position. The articulation control may also permit movement of the locking member when the articulation control is located in the second position.

  • Publication number: 20140276963
    Abstract: A surgical instrument including a power assist device, and its method of use for deploying surgical fasteners, is disclosed. The surgical instrument may include a handle, an elongated shaft extending from the handle, and a surgical fastener deployment system including a driveshaft. The driveshaft is actuatable between at least a first proximal position and a second distal position. A striker is movable relative to the driveshaft and an impact surface is associated with the driveshaft. The impact surface is constructed and arranged to be struck by the striker member to displace the driveshaft to the second distal position and deploy the surgical fastener.

  • Publication number: 20130116708
    Abstract: An instrument for delivering a suture transfascially may include a handle, a shaft extending from the handle, and at least one needle that is moveable to an extended position beyond the end of the shaft. A suture may be delivered transfascially with the instrument. The instrument may include a suture catch associated with each needle for retaining and releasing a suture segment. A shield may be provided to shield the sharp end of each needle when it is moved to the extended position. A method of delivering a transfascial suture may include inserting an instrument into an abdominal cavity and deploying, from within the abdominal cavity, each needle through a soft tissue repair patch and then through at least part of the to abdominal wall. A suture or suture segment may be advanced across the fascia with the at least one needle.
