Surgical Stapler
A straight jaw that clamps a flat stack, forms four staggered rows of staples and divides between the inner two in one stroke. The gap is a machined stop, so the formed height is a fixed dimension of the closed jaw and the material has to suit the cartridge.

Linear cutting stapler, 60 mm cartridge
A straight jaw that clamps a flat stack, forms four staggered rows of staples and divides between the inner two in one stroke. The gap is a machined stop, so the formed height is a fixed dimension of the closed jaw and the material has to suit the cartridge.
Circular stapler, 28 mm
A detachable anvil drawn toward a cartridge head by a screw, forming two concentric staggered rings of staples and cutting an annulus inside them. 50 mm range with an indicator on it, and the indicator reads the gap.

Handle body and grip
The part a hand closes around, and the part that makes the device feel like an instrument rather than a mechanism. It is a moulded shell in two halves over a steel spine, with a ribbed rubber pad where the palm sits and a visible panel seam along its length.
Firing lever and stroke
The lever the finger pulls, hinged on a pin inside the handle shell, with its own rubber pad where a finger bears. It is the first stage of the chain and the only stage a person ever touches.
Force limiter and ratchet pawl
A toothed wheel and a sprung pawl, sitting beside the lever pivot. It turns a stroke that could be abandoned half way into a stroke that can only be advanced or deliberately released.
Shaft and drive rod
The tube between the handle and the jaw, and the drive rod inside it. Everything the hand does has to arrive at the far end through this, and the far end is between 205 and 240 mm away.
Staple driver set
The set of small blocks that sit under the staples and lift them off their seats into the anvil. One driver per staple, or one per pair, each riding on a cam.
Staple cartridge body
The half of the jaw that holds the staples, the drivers and the retainer. On the linear configuration it is a blue moulding about 72 mm long with a deck facing the anvil; on the circular one it is a green head 28 mm across with an annular deck.
Titanium staple wire
25 mm on the circular one. It is the only part of this instrument that is deliberately destroyed by using it, and the only part that stays behind.
Anvil face
The steel face the staple legs are driven against. On the linear configuration it is the upper jaw, 72 mm long and facing down; on the circular one it is a detachable disc 28 mm across facing back toward the head.
Anvil forming pocket
The shallow recess in the anvil face that the staple leg tip enters and turns inside. It is a few tenths of a millimetre deep and it is the single most consequential dimension in this instrument.
Cutting blade
The blade that divides whatever the staples have just secured. On the linear configuration it runs in a slot down the middle of the line; on the circular one it is an annular cutter inside the rings.
