    • A surgical instrument is adapted for applying a plurality of surgical fasteners to body tissue. The surgical instrument includes a frame having a proximal end and a distal end, with a handle positioned at the proximal end and an end effector positioned at the distal end. The end effector is shaped and dimensioned for supporting a cartridge housing and an anvil, the cartridge housing and anvil structure being relatively movable between a first spaced apart position and a second position in close approximation with one another. A firing mechanism is associated with the end effector and the cartridge housing for selective actuation of the fastening elements for treatment of an individual. A tissue retention feature is associated with the cartridge housing and anvil, the tissue retention feature maintaining tissue within the end effector during treatment and including a top tissue retention member and a bottom tissue retention member. The cartridge housing includes at least one staple line along a face of the cartridge housing defining the longitudinal extent of the surgical fasteners being applied via the cartridge module. The staple line includes a top and a bottom, and the top of the staple line is above the top tissue retention member and/or the bottom of the staple line is below the bottom tissue retention member.
    • 外科器械适于将多个外科紧固件应用于身体组织。 手术器械包括具有近端和远端的框架,手柄位于近端,并且末端执行器位于远端。 端部执行器的形状和尺寸用于支撑盒壳体和砧座,盒壳体和砧座结构可在彼此近似近似的第一间隔位置和第二位置之间相对移动。 击发机构与端部执行器和盒壳体相关联,用于选择性地致动用于个体治疗的紧固元件。 组织保持特征与药筒外壳和砧座相关联,组织保持特征在治疗期间维持末端执行器内的组织并且包括顶部组织保持构件和底部组织保持构件。 盒壳体包括沿着盒壳体的表面的至少一个缝合线,其限定通过盒模块施加的外科紧固件的纵向范围。 缝线包括顶部和底部,并且缝合线的顶部在顶部组织保持构件上方和/或缝合线的底部在底部组织保持构件下方。
