Abstract
An apparatus includes an anvil, a closure assembly, a firing assembly, and a casing assembly. The firing assembly includes a staple driver and an annular array of staples. The casing assembly includes a first section and a second section. The first section includes a first handle portion, a first shaft portion, and a tubular casing. The tubular casing slidably houses the staple driver. The first section defines a homogenous continuum of material along the length of the first handle portion, the first shaft portion, and the tubular casing. The second section includes a second handle portion and a second shaft portion. The second handle portion is laterally coupled with the first handle portion. The second shaft portion is laterally coupled with the first shaft portion. The second section defines a homogenous continuum of material along the length of the second handle portion and the second shaft portion.
