    摘要： A circular stapling instrument including a stapling forming assembly that is actuated independently from actuation of the cutting assembly is provided. The instrument includes a handle assembly, an elongate body extending from the handle assembly, a cartridge assembly mounted on a distal end of the elongate body. The cartridge assembly includes a pusher assembly and a knife assembly. The knife assembly is selectively fixed relative to the pusher assembly.

    摘要： A surgical stapling device comprising a housing, an elongated portion, an end effector, and a movable handle disposed in mechanical cooperation with the housing and movable between a first open position and a second approximated position for affecting a function of the end effector. A ratchet mechanism is disposed in mechanical cooperation with the movable handle and is configured to substantially prevent the movable handle from moving towards its first open position until the movable handle reaches a predetermined position.

    摘要： A surgical instrument including a handle assembly, an elongated body portion, a head portion and an elongated channel. The elongated body portion extends distally from the handle assembly. The head portion is disposed adjacent a distal end of the elongated body portion and includes an anvil assembly and a shell assembly. The elongated channel includes a proximal opening and a distal opening. The proximal opening is disposed distally of a proximalmost end of the handle assembly and proximally of the shell assembly. The distal opening is disposed on the shell assembly.

    摘要： A surgical stapling device an elongated body portion having proximal and distal portions, and a head portion positioned adjacent the distal portion of the elongated body portion. The head portion includes a shell assembly and an anvil assembly movable relative to the shell assembly between un-approximated and approximated positions. The anvil assembly includes a center rod and an anvil head connected to the center rod. The center rod includes at least one aperture extending transversely therethrough and configured and dimensioned to receive a flexible member such that the flexible member extends transversely through the center rod.
