1. A device for clamping tissue, comprising:
- an anvil having a first bearing surface; and
a cartridge housing having a second bearing surface, the first and second bearing surfaces together defining an interface upon a mating of the anvil and the cartridge housing, at least one of the anvil and the cartridge housing being rotatable about an axis of rotation defined through the interface to apply a clamping force between the anvil and the cartridge housing, the anvil and the cartridge housing being selectively separable and detachable when no clamping force is applied between the anvil and the cartridge housing.

Abstract
A device for clamping tissue includes a first jaw having a distal portion for communicating with tissue and a proximal portion having a first wing and a second wing. The device also includes a second jaw having a distal portion for communicating with tissue and a proximal portion having a first slot and a second slot, the first slot disposed between a middle structure and a first lateral structure, the second slot disposed between the middle structure and a second lateral structure. The first jaw is rotatably coupleable to the second jaw with the first wing extending into the first slot and the second wing extending into the second slot.

14. A device for clamping tissue, comprising:
-
an anvil having a first bearing surface; a cartridge housing having a second bearing surface, the anvil being rotatable and axially constrained relative to the cartridge housing to apply a clamping force between the anvil and the cartridge housing when the first and second bearing surfaces are mated at an interface; and a positioning member coupled to one of the anvil and the cartridge housing that prevents axial removal of the anvil from the cartridge housing and enables the anvil to rotate with respect to the cartridge housing. - View Dependent Claims (15, 16, 17, 18, 19, 20)
