Surgical stapler apparatus with curved staple pusher

摘要

Surgical stapler apparatus of the type in which a surgical staple is formed around an anvil. The staple is driven by a longitudinally curved pusher which forms an arc of a circle and which is arcuately reciprocal in a similarly curved channel. The distal end portion of the curved channel is substantially tangent to the plane of the distal-most staple in a stack of staples, and the proximal end portion of the staple pusher is substantially parallel to the longitudinal axis of the stack to provide a very compact stapler configuration.
