摘要： An anvil assembly includes a retaining member having a body portion and a frangible portion connected to the body portion, where the frangible portion is positioned to engage a backup member and separates from the body portion during movement of the backup member from a first, proximal position to a second, distal position. The retaining member keeps the backup plate in the proximal position prior to firing of the stapling assembly, and upon separation of the frangible portion allows the backup plate to move to the distal position during firing of the stapling assembly. Proximal force on the backup plate after firing of the stapling assembly is avoided, thereby helping to ensure titling of the anvil assembly.

摘要翻译：砧组件包括保持构件，该保持构件具有主体部分和连接到主体部分的易碎部分，其中脆弱部分定位成接合支撑构件并且在支撑构件从第一近端位置移动期间与身体部分分离到第二个远端位置。保持构件在钉钉组件被击发之前将支撑板保持在近侧位置，并且在分离易碎部分时允许支撑板在钉钉组件的击发期间移动到远侧位置。避免了装订组件点火后在支撑板上的近似力，从而有助于确保砧座组件的标题。

摘要： An improved chip assembly for use in a stapling device includes a housing assembly receivable within a reload assembly. The housing assembly includes a base member defining a cavity and an identification assembly received within the cavity. The chip assembly further includes a plug assembly configured to selectively engage the base member. The plug assembly includes a housing, a wire extending from the housing, a seal member disposed within and extending from a distal end of the housing, and first and second contact members extending through the seal member and from the housing. The seal member is configured to be frictionally received within the base member to secure the plug assembly to the housing assembly in a fluid tight manner.

摘要： The present disclosure relates to a cut ring assembly including a backup member, an intermediate member and a cutting ring body. The intermediate member is formed of a thin, rigid material that is sandwiched between the backup member and the cutting ring body. The thin, rigid material is formed of a material having a hardness less than the hardness of the backup member and greater than the hardness of the cutting ring body. The present disclosure also relates to an anvil assembly including such a cut ring assembly.
