Surgical stapling device
First Claim
1. A surgical stapling device comprising:
- a handle assembly including a firing trigger;
an elongated body portion extending distally from the handle assembly;
a head portion coupled to the elongated body portion, the head portion including an anvil assembly and a shell assembly, the anvil assembly positioned to move relative to the shell assembly between a spaced position and an approximated position;
a trigger lock operably associated with the firing trigger and movable between locked and unlocked positions to selectively prevent actuation of the firing trigger; and
a lockout mechanism operably associated with the anvil assembly, the lockout mechanism positioned to prevent movement of the anvil assembly while the trigger lock is in the unlocked position.

Abstract
A surgical stapling device has a handle assembly, an elongated body portion, a shell assembly housing a plurality of staples and an anvil assembly movable relative to the shell assembly. An approximation mechanism is movable from a first position to a second position to move the anvil assembly relative to the shell assembly between a spaced position and an approximated position. A firing mechanism for advancing the staples is actuable when the approximation assembly is in the second position and the anvil assembly is in the approximated position. A lockout mechanism operatively associated with the approximation mechanism is movable from a non-blocking position to a blocking position, wherein in the non-blocking position the approximation mechanism is movable from the first position to the second position and in the blocking position movement of the approximation mechanism from the second position to the first position is prevented.

11. A surgical stapling device comprising:
-
a handle assembly including an approximation mechanism and a firing trigger; an elongated body portion having a proximal end and a distal end, the elongated body portion extending distally from the handle assembly; a head portion supported on the distal end of the elongated body portion, the head portion including a shell assembly and an anvil assembly, the shell assembly supporting a plurality of staples, the anvil assembly being movable in relation to the shell assembly between a spaced position and an approximated position in response to actuation of the approximation mechanism; a trigger lock mounted on the handle assembly and movable from a locked position to an unlocked position, the trigger lock being positioned to prevent actuation of the firing trigger in the locked position and to enable actuation of the firing trigger in the unlocked position; and a lockout mechanism operably associated with the trigger lock, the lockout mechanism adapted to prevent movement of the anvil assembly from the approximated position to the spaced position when the trigger lock is in the unlocked position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
