    摘要： The cartridge assembly includes a housing, a pusher member, a fastener cartridge body, a circular cartridge buttress member, and a retaining ring member. The pusher member is supported within the housing and movable between a first position and a second position. The fastener cartridge body is supported on the housing and has a tissue engaging surface that extends to an annular edge. One or both of the housing and the fastener cartridge body define an annular containment groove. The circular cartridge buttress member has a body portion and an extension portion. The body portion is supported on the tissue engaging surface of the fastener cartridge body. The extension portion extends from the body portion and over the annular edge of the tissue engaging surface. The retaining ring member is secured within the containment groove to releasably secure the extension portion of the circular cartridge buttress member to the cartridge assembly.

    摘要： An anvil and anvil delivery system is provided which includes a head assembly and a center rod defining a longitudinal axis. The head assembly defines a transverse axis and is pivotally secured to the rod and movable from an operative position wherein the transverse axis is substantially perpendicular to the longitudinal axis and a tilted position wherein the transverse axis defines an acute angle with respect to the longitudinal axis. A flexible tube is secured to the center rod which includes gradations along the length of the tube. The gradations are positioned to provide an indication of a length of the tube remaining in a patient during removal of the tube from the patient. An adapter is secured to one end of the flexible tube and to the center rod. The adapter is configured to secure the anvil assembly to the flexible tube.

    摘要： A surgical stapling instrument including a handle assembly, an elongated body portion extending distally from the handle assembly, a head portion and an indicator. A firing trigger is movable between first and second positions. The head portion includes an anvil assembly and a shell assembly. The anvil assembly is movable in relation to the shell assembly between spaced and approximated positions. The indicator is disposed in mechanical cooperation with the handle assembly and is movable between a first position and a second position in response to movement of the anvil assembly towards its approximated position. The indicator is movable between the second position and a third position in response to firing of the instrument.
