Abstract

A disposable linear surgical stapler includes a handle, anvil, staple cartridge and flexible shaft attaching the handle to the cartridge and transmitting a firing force exerted at the handle to the distant cartridge for sequentially implanting, forming and clinching staples in two staggered staple lines. A flexible cable in the flexible shaft pulls a firing wedge across a plurality of staple drivers in the cartridge. The anvil is adjustable to vary the gap between the anvil and staple cartridge.
