Modular motor driven surgical instruments with status indication arrangements
First Claim
1. A surgical end effector for use in connection with a surgical instrument, the surgical end effector comprising:
- an end effector housing configured for operable attachment to the surgical instrument;
a first end effector drive system operably supported by the end effector housing and configured to linearly move a first end effector actuator between a first linear position and a second linear position in response to first rotary motions applied thereto by the surgical instrument;
a second end effector drive system operably supported by the end effector housing and configured to linearly move a second end effector actuator between a beginning and ending position in response to second rotary motions applied thereto by the surgical instrument;
a first status assembly operably interfacing with the first end effector drive system and end effector housing to provide a first indication on the end effector housing of a linear location of the first end effector actuator; and
a second status assembly operably interfacing with the second end effector drive system and end effector housing to provide a second indication on the end effector housing of a linear location of the second end effector actuator, wherein said second indication is adjacent said first indication, and wherein said first indication and said second indication are observable at the same time.

Abstract
A surgical end effector for use in connection with a surgical instrument. In one form the end effector includes an end effector housing that is configured for operable attachment to the surgical instrument. A first end effector drive system is configured to linearly move a first end effector actuator between a first linear position and a second linear position in response to first rotary motions applied thereto by the surgical instrument. A second end effector drive system is configured to linearly move a second end effector actuator between a beginning and ending position in response to second rotary motions applied thereto by the surgical instrument. The instrument further includes a status assembly arrangement for provide an indication on the end effector housing of a linear location of at least one of the first and second end effector actuators.

11. A shaft assembly, comprising:
-
a housing configured to be attached to a surgical instrument system; an end effector, comprising; a first jaw; a second jaw, wherein said first jaw is movable relative to said second jaw between an open position and a closed position; and a staple cartridge comprising a plurality of staples removably stored therein; a closure system, comprising; a rotatable closure shaft; a closure nut threadably engaged with said closure shaft, wherein said closure nut is configured to translate along said closure shaft to perform a closing stroke to close said first jaw; and a closure indicator extending from said closure nut; a firing system, comprising; a rotatable firing shaft, wherein said firing shaft and said closure shaft are independently rotatable; a firing nut threadably engaged with said firing shaft, wherein said firing nut is configured to translate along said firing shaft to perform a firing stroke to eject said staples from said staple cartridge; and a firing indicator extending from said firing nut; a closure slot defined in said housing, wherein said closure indicator is observable by way of said closure slot; and a firing slot defined in said housing, wherein said firing slot is parallel to said closure slot, wherein said firing indicator is observable by way of said firing slot, and wherein said closure slot is adjacent said firing slot such that the position of said closure indicator and the position of said firing indicator are observable at the same time.
