摘要：
A surgical loading unit (10) for use with a surgical handle assembly (1000) includes a handle mount (12) dimensioned for mounting to the handle assembly (1000), an outer member (56) extending from the handle mount (12), a staple cartridge assembly (16) mounted to the distal end of the outer member (56), and an anvil assembly (18) couplable relative to the staple cartridge assembly (16). A staple pusher (60) is at least partially disposed within the outer member (56) and operatively coupled to the staple cartridge assembly (16). The staple pusher (60) is adapted for longitudinal movement to eject staples from the staple cartridge assembly (16). An anvil approximator (94) is at least partially disposed within the outer member (56) and is operatively coupled to the anvil assembly (18). The anvil approximator (94) is adapted for movement between first and second positions corresponding to closed and open conditions of the anvil assembly (18) relative to the staple cartridge assembly (16). A lock member (24) is mounted to the handle mount (12). The lock member (12) is adapted to move from a lock position in secured engagement with the staple pusher (60) and the anvil approximator (94) to a release position releasing the staple pusher (60) and the anvil approximator (94) upon mounting of the handle mount (12) relative to the surgical handle assembly (1000).La présente invention concerne une unité chirurgicale de chargement (10) destinée à être utilisée avec un ensemble poignée chirurgicale (1 000) comprenant un support (12) de poignée dimensionné pour être monté sur l'ensemble poignée (1 000), un élément externe (56) s'étendant à partir du support (12) de poignée, un ensemble cartouche (16) d'agrafes monté sur l'extrémité distale de l'élément externe (56), et un ensemble enclume (18) pouvant être accouplé par rapport à l'ensemble cartouche (16) d'agrafes. Un poussoir (60) d'agrafes est disposé au moins en partie à l'intérieur de l'élément externe (56) et accouplé fonction
