Stapling instrument for use with a surgical robot
A stapling instrument for use with a surgical robot is disclosed. The stapling instrument comprises an interface including a plurality of rotary members, a shaft rotatable about a longitudinal axis by a first rotary member, an end effector rotatably connected to the shaft about an articulation joint, an articulation cable, a coupling member, and a firing cable. The end effector comprises a first jaw, a second jaw, and a staple cartridge comprising staples. The articulation cable operably connects to a second rotary member and is operable to pull the articulation cable and articulate the end effector. The coupling member is movable through a first stroke to move the second jaw toward the first jaw and movable through a second stroke to fire the staples. The firing cable operably connects to a third rotary member and is operable to drive the coupling member through the first stroke and the second stroke.
1. A stapling instrument for use with a surgical robot, comprising:
an interface comprising a first rotary member, a second rotary member, a third rotary member, and a fourth rotary member;
a shaft extending from the interface, wherein the shaft is rotatable about a longitudinal axis by the first rotary member;
an end effector rotatably connected to the shaft about an articulation joint, wherein the end effector comprises:
a first jaw;
a second jaw rotatable relative to the first jaw; and
a staple cartridge comprising staples removably stored therein;
an articulation cable operably connected to the second rotary member and the end effector, wherein the second rotary member is operable to pull the articulation cable and articulate the end effector;
a coupling member comprising a first portion configured to engage the first jaw and a second portion configured to engage the second jaw, wherein the coupling member is movable through a first stroke to move the second jaw toward the first jaw, and wherein the coupling member is movable through a second stroke to fire the staples from the staple cartridge; and
a firing cable operably connected to the third rotary member and the coupling member, wherein the third rotary member is operable to drive the coupling member through the first stroke and the second stroke.
2. A stapling instrument for use with a surgical robot, comprising:
an interface comprising a plurality of rotary members;
a shaft extending from the interface, wherein the shaft is rotatable about a longitudinal axis by a first rotary member of the plurality of rotary members;
an end effector rotatably connected to the shaft about an articulation joint, wherein the end effector comprises:
a first jaw;
a second jaw rotatable relative to the first jaw; and
a staple cartridge comprising staples removably stored therein;
an articulation cable operably connected to a second rotary member of the plurality of rotary members and the end effector, wherein the second rotary member is operable to pull the articulation cable and articulate the end effector;
a coupling member comprising a first portion configured to engage the first jaw and a second portion configured to engage the second jaw, wherein the coupling member is movable through a first stroke to move the second jaw toward the first jaw, and wherein the coupling member is movable through a second stroke to fire the staples from the staple cartridge; and
a firing cable operably connected to a third rotary member of the plurality of rotary members and the coupling member, wherein the third rotary member is operable to drive the coupling member through the first stroke and the second stroke.
3. A stapling instrument for use with a surgical robot, comprising:
an interface comprising a plurality of rotary members;
a shaft extending from the interface, wherein the shaft is rotatable about a longitudinal axis by a first rotary member of the plurality of rotary members;
an end effector rotatably connected to the shaft about an articulation joint, wherein the end effector comprises:
a first jaw; and
a second jaw rotatable relative to the first jaw;
an articulation cable operably connected to a second rotary member of the plurality of rotary members and the end effector, wherein the second rotary member is operable to pull the articulation cable and articulate the end effector;
a coupling member comprising a first portion configured to engage the first jaw and a second portion configured to engage the second jaw, wherein the coupling member is movable through a closing motion to move the second jaw toward the first jaw, and wherein the coupling member is movable through a staple firing motion; and
a firing cable operably connected to a third rotary member of the plurality of rotary members and the coupling member, wherein the third rotary member is operable to drive the coupling member through the closing motion and the staple firing motion.
4. The stapling instrument of claim 3 , further comprising a staple cartridge.
