Abstract
A surgical instrument. The surgical instrument comprises a plurality of sensors, and a status module releasably connected to the surgical instrument. The status module comprises a plurality of contacts, a circuit, and a plurality of indicators. Each individual contact is in electrical communication with a different sensor. The circuit is in electrical communication with at least one of the contacts. At least one of the indicators is in electrical communication with the circuit.
Claims16
A powered surgical stapler, comprising:
- a housing;
- a motor-driven input configured to generate a rotary motion;
- an actuator movable relative to said housing between an unactuated position and an actuated position;
- an elongate shaft extending from said housing;
- an end effector extending from said elongate shaft, wherein said end effector comprises a first jaw and a second jaw movable relative to said first jaw between an unclamped state and a clamped state in response to said actuator, and wherein said second jaw is moved from said unclamped state to said clamped state during a closure stroke in response to said actuator moving from said unactuated position toward said actuated position;
- a firing driver configured to translate within said end effector during a firing stroke in response to said rotary motion, wherein said firing stroke and said closure stroke are separate and distinct, wherein said firing driver is resettable to translate through another firing stroke, wherein said firing driver comprises a cam, and wherein said cam cammingly engages said second jaw during said firing stroke;
- a firing lockout;
- and
- a display which selectively displays:
- whether a predetermined amount of time has elapsed after said end effector is transitioned into said clamped state;
- the position of said firing driver;
- a locked-out status indicative of said firing driver being prevented from performing said firing stroke by said firing lockout;
- and
- the force experienced by said firing driver during said firing stroke.

A powered surgical stapler, comprising:
- a housing comprising a motor configured to generate a rotary motion;
- an actuator movable relative to said housing between an unactuated position and an actuated position;
- an elongate shaft extending from said housing;
- an end effector extending from said elongate shaft, wherein said end effector comprises a first jaw and a second jaw movable relative to said first jaw between an unclamped state and a clamped state in response to said actuator, wherein said second jaw is moved from said unclamped state to said clamped state during a closure stroke in response to said actuator moving from said unactuated position toward said actuated position;
- a firing driver configured to translate through said end effector during a firing stroke in response to said rotary motion of said motor, wherein said closure stroke and said firing stroke are separate and distinct, wherein said firing driver is resettable to translate through another firing stroke, wherein said firing driver comprises a cam, and wherein said cam is configured to cammingly engage said second jaw during said firing stroke;
- and
- a firing lockout,
- wherein said powered surgical stapler is configured to selectively indicate to a user:
- whether a predetermined amount of time has elapsed after said end effector is transitioned into said clamped state;
- the position of said firing driver;
- a locked-out status indicative of said firing driver being prevented from performing said firing stroke by way of said firing lockout;
- and
- the force experienced by the firing driver during said firing stroke.
10 more elements
A surgical stapling instrument system, comprising:
- a housing;
- a motor-driven input configured to receive a rotary motion;
- an actuatable input configured to receive a user instruction;
- an elongate shaft extending from said housing;
- an end effector extending from said elongate shaft, wherein said end effector comprises a first jaw and a second jaw, and wherein said second jaw is movable from an unclamped state to a clamped state during a closure stroke to compress tissue between said first and said second jaw in response to an actuation of said actuatable input;
- a firing driver configured to translate within said end effector during a firing stroke in response to said rotary motion;
- a firing lockout that prevents said firing driver from performing said firing stroke when said end effector is not in said clamped state;
- and
- a display that selectively displays:
- the progress of said firing driver during said firing stroke;
- and
- a wait time indication associated with a compression of tissue between said first jaw and said second jaw, wherein said firing driver comprises a first cam structured to engage said first jaw and a second cam structured to engage said second jaw.
