摘要： A circular stapling device (10) includes a shell assembly (20) and an anvil assembly (16). The shell assembly includes a housing (40), a staple cartridge supported on the housing, an annular knife (62) supported within the housing, and a biasing member (64) supported within the housing. The anvil assembly includes a center rod and an anvil head that supports a cut ring (33) that is axially aligned with the annular knife. The biasing member is positioned within the housing and extends to a position distally of the annular knife when the annular knife is in the retracted position to shield the annular knife. The anvil assembly is movably supported in relation to the shell assembly between an unapproximated position and an approximated position, wherein in the approximated position, the biasing member is engaged with the cut ring and urges the cut ring in a distal direction.

摘要： A surgical device (100) is disclosed. The surgical device includes: a jaw assembly (300) including a first jaw (306) and a second jaw (308) moveable relative to the first jaw; and an articulating assembly (230) removably coupled to the proximal end of the jaw assembly, the articulating including a distal joint member (232), a proximal joint member (234), and a pivot pin (505) fixedly coupled to the distal joint member and rotatably coupled to the proximal joint member, wherein the jaw assembly and the distal joint member define a first longitudinal axis extending between a proximal end of the jaw assembly and a distal end of the distal joint member, and the proximal joint member defines a second longitudinal axis. The surgical device also includes a first rotatable drive shaft (218a) including a first gear element meshingly engaged with a pivoting gear element fixedly coupled to the pivot pin, wherein rotational and longitudinal movement of the first rotatable drive shaft pivots the jaw assembly relative to the proximal joint member about a pivot axis defined by the pivot pin that is perpendicular to the first and second longitudinal axes.

摘要： An anvil assembly (10) is provided. The anvil assembly includes an anvil center rod (14), a head (12) assembly pivotally secured to the anvil center rod assembly (14) from an operative position to a tilted position, and a sleeve (15) slidably disposed about the anvil center rod. The sleeve (15) is associated with the head assembly such that movement of the head assembly (12) from the operative position towards the tilted position effects proximal movement of the sleeve about the anvil center rod (14).
