Abstract

Embodiments include an end effector for use by a surgeon to staple an anatomical structure of a patient, the end effector including a first jaw having a first end, a second end, a longitudinal axis, and an anvil having an anvil face; a second jaw having a first end, a second end, a longitudinal axis, and a cartridge operably configured to house a plurality of staples, the cartridge having a cartridge face; a first coupling that couples the first end of the first jaw to the first end of the second jaw; and a second coupling that movably couples the second end of the first jaw to the second end of the second jaw, where the second coupling includes a rigid link connected to the first jaw and the second jaw.

Claims27

Dependent claims

An end effector for use by a surgeon to staple an anatomical structure of a patient during a minimally invasive procedure, the anatomical structure having a first side and a second side, the end effector comprising:

(a) a first jaw having a first end, a second end, a longitudinal axis, and an anvil, the anvil comprising an anvil face positionable on the first side of the anatomical structure;
(b) a second jaw having a first end, a second end, a longitudinal axis, and a cartridge operably configured to house a plurality of staples, the cartridge having a cartridge face positionable on the second side of the anatomical structure;
(c) a first coupling that couples the first end of the first jaw to the first end of the second jaw;
and
(d) a second coupling that movably couples the second end of the first jaw to the second end of the second jaw, wherein the second coupling includes a rigid link having a distal portion and a proximal portion and a slot defined by the first jaw or the second jaw that retains the rigid link such that the rigid link is slidable within the slot when the end effector is in both a first open position and a second closed position;
and wherein the distal and proximal portions of the rigid link are respectively movably coupled to the second end of the first jaw and the second end of the second jaw when the end effector is in both the first open position and in the second closed position.

3 more elements

(a) an anvil comprising a first end, a second end, an anvil face, a length, and a width, wherein the length of the anvil is at least ten times the width of the anvil;
(b) a cartridge comprising a first end, a second end, a cartridge face, a length, and a width, wherein the length of the cartridge is at least ten times the width of the anvil, the cartridge being operably configured to house a plurality of staples, wherein the first end of the anvil is coupled with the first end of the cartridge and the second end of the anvil is movably coupled to the second end of the cartridge;
(c) a rigid link having a distal portion and a proximal portion;
and
(d) an elongated slot defined by the anvil or the cartridge that slidably retains the rigid link when the end effector is in both a first open position and in a second closed position;
and wherein the distal and proximal portions of the rigid link are respectively movably coupled to the second end of the anvil and the second end of the cartridge when the end effector is in both the first open position and in the second closed position.

3 more elements

(a) an anvil that includes a first end, a second end, and an anvil face positionable on the first side of the anatomical structure;
(b) a cartridge operably configured to house a plurality of staples, the cartridge comprising a first end, a second end, and a cartridge face positionable on the second side of the anatomical structure, the cartridge face including a channel extending from the first end of the cartridge to the second end of the cartridge, wherein the first end of the cartridge is pivotally coupled with the first end of the anvil;
(c) a blade, the blade comprising a cutting surface and at least one elongated arm, wherein the at least one elongated arm is slidably engaged with the channel;
(d) a rigid link having a distal portion and a proximal portion;
and
(e) an elongated slot defined by the anvil or the cartridge that slidably retains the rigid link when the end effector is in both a first open position and a second closed position;
and wherein the distal and proximal portions of the rigid link are respectively movably coupled to the second end of the anvil and the second end of the cartridge when the end effector is in both the first open position and in the second closed position.
