SURGICAL INSTRUMENTS WITH IMPROVED CLOSURE ARRANGEMENTS
First Claim
1. A surgical instrument, comprising:
- a surgical end effector comprising first and second jaw members wherein application of a closure motion to at least one of said first and second jaw members results in the movement of the at least one of said first and second jaw members to a closed position relative to the other of said first and second jaw members; and
a closure system comprising;
an axially movable closure member configured to apply said closure motion to said at least one of said first and second jaw members;
a closure actuator including a first actuator portion configured to move axially through a first range of axial travel upon actuation of said closure actuator; and
a closure transmission interfacing with said first actuator portion and comprising a second actuator portion interfacing with said axially movable closure member such that upon actuation of said closure actuator, said second actuator portion moves said axially movable closure member through a second range of axial travel that is greater than said first range of axial travel.

Abstract
A surgical instrument that includes jaw members, at least one of which may be moved to closed positions relative to the other jaw member upon actuation of a closure actuator. Actuation of the closure actuator causes an axially moveable closure member to apply closure motions to at least one of the jaw members. In at least one form, the closure actuator includes a first actuator portion that is configured to move through a first range of axial travel upon actuation of the closure actuator. A second actuator portion interfaces with the axially movable closure member such that upon actuation of said closure actuator, the second actuator portion moves the axially movable closure member through a second range of axial travel that is greater than the first range of axial travel.

13. A surgical instrument, comprising:
-
an end effector comprising; a surgical staple cartridge; and an anvil, at least one of said surgical staple cartridge and said anvil being movable in response to a closure motion applied thereto and wherein said surgical instrument further comprises; a shaft assembly operably interfacing with at least one of said surgical staple cartridge and said anvil; a handle operably coupled to said shaft assembly; a closure actuator operably supported by said handle and including a first actuator portion configured to move axially a predetermined first range of axial travel upon actuation of said closure actuator; an axially movable closure member configured to apply said closure motion to the at least one of said surgical staple cartridge and said anvil; and a closure transmission interfacing with said first actuator portion and comprising a second actuator portion interfacing with said axially movable closure member such that upon actuation of said closure actuator, said second actuator portion moves said axially movable closure member through a second range of axial travel that is greater than said first range of axial travel. - View Dependent Claims (14, 15, 16, 17)
