MOTOR DRIVEN SURGICAL FASTENER DEVICE WITH CUTTING MEMBER LOCKOUT ARRANGEMENTS
First Claim
1. A surgical fastener apparatus comprising:
- a. a handle, an elongated shaft having a proximal end attached to said handle and a distal end extending therefrom, an end effector comprising a pair of jaws pivoted at a proximal end thereof and movable between an open and closed position, and a cartridge containing a plurality of surgical fasteners, said cartridge attached to said end effector;
b. an electrically powered actuator for deploying said surgical fasteners, said actuator comprising a power source and a motor;
c. a first trigger attached to said handle for moving said end effector from said open to said closed position, and a second trigger attached to said handle for activating said actuator;
d. a first lockout mechanism for preventing current from flowing from said power source to said motor unless said end effector is in its closed position; and
e. a second lockout mechanism having a locked and unlocked position, said second lockout mechanism for preventing movement of said second trigger until said second lockout mechanism is moved to said unlocked position.

Abstract
A surgical fastener apparatus having a handle, an elongated shaft having a proximal end attached to the handle and a distal end extending therefrom. An end effector including a pair of jaws pivoted at a proximal end thereof and movable between an open and closed position. A cartridge containing a plurality of surgical fasteners, the cartridge attached to the end effector. An electrically powered actuator for deploying the surgical fasteners, the actuator having a power source and a motor. A first trigger attached to the handle for moving the end effector from the open to the closed position, and a second trigger attached to the handle for activating the actuator. A first lockout mechanism for preventing current from flowing from the power source to the motor unless the end effector is in its closed position a second lockout mechanism having a locked and unlocked position, the second lockout mechanism for preventing movement of the second trigger until the second lockout mechanism is moved to the unlocked position.

11. A surgical fastener apparatus comprising:
-
a handle; an end effector operably coupled to said handle and having a movable anvil supported thereon, said movable anvil movable between open and closed positions in response to open and closing motions applied to a closure trigger operably supported on said handle; an actuator movable within said end effector between an unactuated position to actuated positions within said end effector; an electric motor operably interfacing with said actuator to selectively apply a distal driving motion thereto to move said actuator from said unactuated position to said actuated positions and to selectively apply a proximal driving motion to said actuator to retract said actuator to said unactuated position from said actuated positions; a power source connected to said motor for electrically powering the motor; and a current control circuit connected to the power source for controlling current supplied to said motor from said power source, said current control circuit comprising; a closure lock switch connected to said power source and said motor such that when said closure trigger is retained in a locked position wherein said anvil is retained in said closed position, said closure lock switch permits current to flow from said power source to said motor and when said closure trigger is not in said locked position, said closure lock switch prevents current from flowing from said power source to said motor; and a start switch connected to said power source and said motor and preventing current from flowing from said power source to said motor unless said start switch is manually activated. - View Dependent Claims (12, 13, 14)

15. A surgical fastener apparatus comprising:
-
a handle; an end effector operably coupled to said handle and having a movable anvil supported thereon, said movable anvil movable between open and closed positions in response to open and closing motions applied to a closure trigger operably supported on said handle; an actuator movable within said end effector between an unactuated position to actuated positions within said end effector; an electric motor operably interfacing with said actuator to selectively apply a distal driving motion thereto to move said actuator from said unactuated position to said actuated positions and to selectively apply a proximal driving motion to said actuator to retract said actuator to said unactuated position from said actuated positions; a power source connected to said motor for electrically powering the motor; a firing trigger operably supported on said handle and movable between actuated and unactuated positions; a firing switch coupled to said power source and said motor and interfacing with said firing trigger such that, upon movement of said firing trigger from said unactuated position to said actuated positions, said firing switch permits current to flow to said motor to apply said distal driving motion to said actuator; a closure lock switch connected to said power source and said motor such that when said closure trigger is retained in a locked position wherein said anvil is retained in said closed position, said closure lock switch permits current to flow from said power source to said motor and when said closure trigger is not in said locked position, said closure lock switch prevents current from flowing from said power source to said motor; and a movable lock member movable between a first position wherein movement of said second trigger from said unactuated position to said actuated positions is prevented and a second position wherein said second trigger may be moved from said unactuated position to said actuated positions.
