Motor-driven surgical cutting and fastening instrument with tactile position feedback
A surgical instrument is disclosed including an end effector, a firing drive, and a mechanical closure system. The end effector includes a first jaw including a proximal end and a distal end, a second jaw rotatable relative to the first jaw between an open position and a closed position, a staple cartridge including staples removably stored therein, and a cutting member movable toward the distal end during a staple firing stroke. The firing drive includes a drive shaft operable to move the cutting member through the staple firing stroke, a gear drive train operably coupled to the drive shaft, an electric motor configured to actuate the gear drive train, and a firing trigger actuatable to actuate the electric motor. The mechanical closure system includes a closure member movable distally to close the second jaw during a closure stroke and a closure trigger rotatable between an unactuated position and an actuated position to advance the closure member through the closure stroke. The firing trigger pivots from a recessed position to an exposed user-accessible position when the closure trigger is placed in the actuated position.
1. A surgical instrument, comprising:
an end effector, comprising:
a first jaw comprising a proximal end and a distal end;
a second jaw rotatable relative to said first jaw between an open position and a closed position;
a staple cartridge including staples removably stored therein; and
a cutting member movable toward said distal end during a staple firing stroke;
a firing drive, comprising:
a drive shaft operable to move said cutting member through said staple firing stroke;
a gear drive train operably coupled to said drive shaft;
an electric motor configured to actuate said gear drive train; and
a firing trigger actuatable to actuate said electric motor; and
a mechanical closure system, comprising:
a closure member movable distally to close said second jaw during a closure stroke; and
a closure trigger rotatable between an unactuated position and an actuated position to advance said closure member through said closure stroke, wherein said firing trigger pivots from a recessed position to an exposed user-accessible position when said closure trigger is placed in said actuated position.
2. The surgical instrument of claim 1 , wherein said staple cartridge is replaceable.
3. The surgical instrument of claim 1 , wherein said cutting member comprises a first cam configured to engage said first jaw and a second cam configured to engage said second jaw.
4. The surgical instrument of claim 1 , wherein said closure trigger is positioned proximally relative to said firing trigger.
5. The surgical instrument of claim 1 , further comprising a latch configured to releasably hold said closure trigger in said actuated position.
6. The surgical instrument of claim 5 , wherein said firing trigger is stationed in said exposed user-accessible position when said closure trigger is held in said actuated position by said latch.
7. The surgical instrument of claim 6 , further comprising a spring configured to retract a firing member back into said recessed position when said closure trigger is released by said latch.
8. A surgical instrument, comprising:
an end effector, comprising:
a first jaw comprising a proximal end and a distal end;
a second jaw rotatable relative to said first jaw between an open position and a closed position;
a staple cartridge including staples removably stored therein; and
a cutting member movable toward said distal end during a staple firing stroke;
a firing drive, comprising:
a drive shaft operable to move said cutting member through said staple firing stroke;
a gear drive train operably coupled to said drive shaft; and
an electric motor configured to actuate said gear drive train;
a mechanical closure system comprising a closure member movable distally to close said second jaw during a closure stroke; and
a handle, comprising:
a grip;
a closure trigger rotatable toward said grip between an unactuated position and an actuated position to advance said closure member through said closure stroke; and
a firing trigger actuatable toward said grip to actuate said electric motor, wherein said firing trigger pivots from a recessed position to an exposed user-accessible position when said closure trigger is placed in said actuated position.
9. The surgical instrument of claim 8 , wherein said staple cartridge is replaceable.
10. The surgical instrument of claim 8 , wherein said cutting member comprises a first cam configured to engage said first jaw and a second cam configured to engage said second jaw.
11. The surgical instrument of claim 8 , wherein said closure trigger is positioned proximally relative to said firing trigger.
12. The surgical instrument of claim 8 , further comprising a latch configured to releasably hold said closure trigger in said actuated position.
13. The surgical instrument of claim 12 , wherein said firing trigger is stationed in said exposed user-accessible position when said closure trigger is held in said actuated position by said latch.
14. The surgical instrument of claim 13 , further comprising a spring configured to retract a firing member back into said recessed position when said closure trigger is released by said latch.
