  • Patent number: 8353436
    Abstract: A surgical instrument having a handle portion, an elongated portion defining a longitudinal axis therethrough, an end effector, and a pin. The elongated portion extends distally from the handle portion. The end effector is disposed adjacent the elongated portion and includes a first jaw member and a second jaw member. The pin is disposed in mechanical cooperation with the first jaw member and includes an engaging section. In operation, the pin moves between a first position and a second position. While in the first position, the engaging portion of the pin is spaced from the second jaw member. In the second position, the engaging portion of the pin engages the second jaw member. The second jaw member includes a locking structure configured to maintain the position of the second jaw member with respect to the first jaw member during actuation of the end effector.

  • Patent number: 8328061
    Abstract: A surgical instrument for surgically joining tissue is provided. The surgical instrument includes a handle assembly that includes an actuator member. An end effector is operatively disposed adjacent a distal portion of an elongated shaft of the surgical instrument. The end effector includes a first jaw member pivotably disposed with respect to a second jaw member. The end effector is movable between a first position where the jaw members are spaced from one another, and a second position where the jaw members are in an approximated position. Each of the first and second jaw members includes a respective longitudinal track. An actuation assembly is disposed in mechanical cooperation with the end effector, wherein actuation of the actuation member causes the actuation assembly to translate from a distal portion of the end effector towards a proximal portion of the end effector through the tracks in the first and second jaw members.
