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.

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 surgical end effector for use in connection with a surgical instrument, the surgical end effector comprising:
-
an end effector tool head comprising; a supporting structure configured to operably support a staple cartridge therein; an anvil portion operably supported in confronting relationship with the supporting structure and wherein the surgical end effector further comprises; an end effector housing configured for operable attachment to the surgical instrument; a closure drive system operably supported in the end effector housing and configured to receive first rotary motions from the surgical instrument when the end effector housing is coupled to the surgical instrument, the closure drive system operably interfacing with a closure beam assembly that is coupled to the anvil portion to linearly move the anvil portion between open and closed positions upon application of the first rotary motions to the closure drive system; a firing drive system operably supported in the end effector housing and configured to receive second rotary motions from the surgical instrument when the end effector housing is coupled to the surgical instrument, the firing drive system operably interfacing with a firing bar assembly that interfaces with the supporting structure to linearly move firing bar and the supporting structure attached thereto between an unactuated position and an actuated position wherein staples are driven from the staple cartridge into forming contact with the anvil portion upon application of the second rotary motions to the firing drive system; a closure status assembly operably interfacing with the closure drive system and end effector housing to provide a closure indication on the end effector housing of a linear location of the closure beam assembly; and a firing indicator member operably interfacing with the firing drive system and end effector housing to provide a firing indication on the end effector housing of a linear location of the firing bar assembly between the unactuated and actuated positions. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
