Abstract

A surgical instrument comprising an end effector, an articulation system, a firing system, a closure system, a lock system, and a control unit is disclosed. The end effector comprises a pair of movable jaws. The articulation system articulates the end effector when the articulation system is in an active state. The closure system is actuatable to move the pair of jaws. The lock system prevents the closure system from actuating when the lock system is in a locked state. The control unit controls the supply of power from a power source to the articulation system, the firing system, and the lock system. The control unit transitions the lock system to the locked state and prevents the supply of power from the power source to the firing system when the articulation system is in the active state.

First claim

What is claimed is:

1 . A surgical instrument, comprising:
a handle; an elongate shaft extending from said handle, wherein said elongate shaft defines a longitudinal shaft axis; an end effector extending from said elongate shaft, comprising:
a first jaw; and
a second jaw movable relative to said first jaw between an open position and a closed position;
an articulation joint, wherein said end effector is rotatably coupled to said elongate shaft about said articulation joint, and wherein said end effector is rotatable about an articulation axis that is transverse to said longitudinal shaft axis; a motor-powered articulation system configured to rotate said end effector about said articulation axis, wherein said articulation system is operated in a plurality of states, and wherein said plurality of states comprises an active state where said end effector is being articulated and an inactive state where said end effector is not being articulated; a motor-powered firing system comprises a firing member movable from an unfired position to a fired position during a firing stroke; a closure system comprising a closure trigger operably engaged with said end effector, wherein said closure trigger is actuatable relative to said handle between an unclamped position where said second jaw is in said open position and a clamped position where said second jaw is in said closed position; a lock solenoid movable between an actuated position where said lock solenoid is engaged with a portion of said closure system and an unactuated position where said lock solenoid is not engaged with said closure system, wherein said closure system is prevented from being actuated when said lock solenoid is in said actuated position; a power source configured to supply power to said articulation system, said firing system, and said lock solenoid; and a control unit configured to control the supply of power from said power source to said articulation system, said firing system, and said lock solenoid, wherein said control unit moves said lock solenoid to said actuated position and prevents the supply of power from said power source to said firing system when said articulation system is in said active state.

2 . The surgical instrument of claim 1 , further comprising a closure sensor in signal communication with said control unit, wherein said closure sensor is configured to detect when said closure trigger is in said clamped position.

3 . The surgical instrument of claim 2 , wherein said control unit is configured to prevent the supply of power from said power source to said firing system when said closure trigger is not in said clamped position.

4 . The surgical instrument of claim 1 , wherein one of said first jaw and said second jaw is configured to receive a staple cartridge, and wherein the other of said first jaw and said second jaw comprises an anvil.

5 . The surgical instrument of claim 4 , further comprising said staple cartridge.

6 . A surgical instrument, comprising:
a handle; an elongate shaft extending from said handle, wherein said elongate shaft defines a longitudinal shaft axis; an end effector extending from said elongate shaft, wherein said end effector comprises a pair of jaws movable between an open position and a closed position; an articulation joint, wherein said end effector is rotatably coupled to said elongate shaft about said articulation joint, and wherein said end effector is rotatable about an articulation axis that is transverse to said longitudinal shaft axis; a powered articulation system configured to rotate said end effector about said articulation axis, wherein said articulation system is operable in a plurality of states, and wherein said plurality of states comprises an active state where said end effector is being articulated and an inactive state where said end effector is not being articulated; a powered firing system comprises a firing member movable from an unfired position to a fired position during a firing stroke; a closure system comprising a closure trigger operably engaged with said end effector, wherein said closure trigger is actuatable relative to said handle between an unclamped position where said end effector is in said open position and a clamped position where said end effector is in said closed position; a lock system operable in a plurality of states, wherein said plurality of states comprises a locked state where said lock system locks said closure system and an unlocked state where said lock system unlocks said closure system, and wherein said closure system is prevented from being actuated when said lock system is in said locked state; a power source configured to supply power to said articulation system, said firing system, and said lock system; and a control unit configured to control the supply of power from said power source to said articulation system, said firing system, and said lock system, wherein said control unit transitions said lock system to said locked state and prevents the supply of power from said power source to said firing system when said articulation system is in said active state.

7 . The surgical instrument of claim 6 , further comprising a closure sensor in signal communication with said control unit, wherein said closure sensor is configured to detect when said closure trigger is in said clamped position.

8 . The surgical instrument of claim 7 , wherein said control unit is configured to prevent the supply of power from said power source to said firing system when said closure trigger is not in said clamped position.

9 . The surgical instrument of claim 6 , wherein said end effector is configured to receive a staple cartridge.

10 . The surgical instrument of claim 9 , further comprising said staple cartridge.

11 . A surgical instrument, comprising:
a handle; an elongate shaft extending from said handle, wherein said elongate shaft defines a longitudinal shaft axis; an end effector extending from said elongate shaft, comprising:
a first jaw; and
a second jaw movable relative to said first jaw between an open position and a closed position;
an articulation joint, wherein said end effector is rotatably coupled to said elongate shaft about said articulation joint, and wherein said end effector is rotatable about an articulation axis that is transverse to said longitudinal shaft axis; a power source; a powered articulation system configured to rotate said end effector about said articulation axis when power is supplied from said power source; a closure system, comprising:
a closure trigger operably engaged with said end effector, wherein said closure trigger is actuatable relative to said handle between an unclamped position where said second jaw is in said open position and a clamped position where said second jaw is in said closed position; and
a closure sensor configured to detect the position of said closure trigger; and
a control unit configured to control the supply of power from said power source to said articulation system, wherein said closure sensor is in signal communication with said control unit, and wherein said control unit prevents the supply of power from said power source to said articulation system when said closure sensor detects said closure trigger is not in said unclamped position.

12 . The surgical instrument of claim 11 , further comprising a powered firing system comprising a firing member movable from an unfired position to a fired position during a firing stroke, wherein said power source is configured to supply power to said firing system, and wherein said control unit is configured to control the supply of power to said firing system.
