Surgical stapling and cutting device

1. A medical device, comprising:

a laparoscopic shaft having proximal and distal ends and defining a shaft axis;

a surgical end effector at the distal end of the shaft;

a surgical procedure actuator carrying out a surgical procedure on tissue at the end effector when actuated; and

a rotating knob at the proximal end of the shaft configured to:

rotate the end effector with respect to the shaft about the shaft axis when rotated; and

actuate the procedure actuator when slid in a proximal direction.

2. The medical device according to claim 1 , further comprising a pistol-shaped handle connected at the proximal end of the shaft and having a distal end at which is disposed the rotating knob.

3. The medical device according to claim 2 , wherein:

the pistol-shaped handle has a stapler-closing device; and

the end effector is a surgical stapling end effector having a pair of opposing stapling surfaces, at least one of the stapling surfaces being operable to move with respect to the other of the stapling surfaces upon actuation of the stapler-closing device to apply a compressive force to tissue therebetween.

4. The medical device according to claim 2 , wherein:

the end effector is a surgical stapling end effector having a stapling device with staples and a cutting device with a blade;

the handle has:

a stapler closing actuator closing the stapling device when actuated; and

a firing actuator that, when actuated:

staples with the stapling device; and

cuts with the cutting device; and

the stapler closing actuator and the staple firing actuator are different from the rotating knob.

5. The medical device according to claim 2 , wherein:

the end effector is a surgical stapling end effector having a stapling device with staples and a cutting device with a blade;

the handle has:

a stapler closing actuator closing the stapling device when actuated; and

a firing actuator that, when actuated:

staples with the stapling device; and

cuts with the cutting device; and

the stapler closing actuator and the staple firing actuator are actuators that are different from the rotating knob.

6. The medical device according to claim 1 , wherein the end effector is rotationally fixedly connected to the rotating knob and rotates the end effector when rotated about the shaft axis.

7. The medical device according to claim 6 , wherein the rotating knob permits both:

a rotation of the end effector when rotated about the shaft axis; and

an actuation of the procedure actuator when slid proximally.

8. The medical device according to claim 6 , wherein the rotating knob permits simultaneous rotation of the end effector and actuation of the surgical procedure actuator when rotated about the shaft axis and slid proximally.

9. The medical device according to claim 1 , wherein:

the procedure actuator is a locking device of the end effector; and

actuation of the procedure actuator by proximal movement of the rotating knob unlocks the locking device.

10. The medical device according to claim 9 , wherein:

the procedure actuator has an unactuated state and an actuated state;

the locking device has a locked state and an unlocked state; and

the procedure actuator:

in the actuated state when the rotating knob is moved proximally, changes the locking device from the locked state to the unlocked state; and

changes the locking device from the unlocked state to the locked state when the rotating knob is released after being moved proximally.

11. The medical device according to claim 1 , wherein the end effector further comprises a knife assembly disposed to cut tissue at the end effector.

12. The medical device according to claim 1 , wherein the end effector comprises one of a circular surgical staple head and a linear surgical staple head.

13. A medical device, comprising:

a pistol-shaped handle having a distal portion;

a laparoscopic shaft having a proximal end at the distal portion, a distal end, and defining a shaft axis;

a surgical end effector at the distal end of the shaft;

a surgical procedure actuator carrying out a surgical procedure on tissue at the end effector when actuated; and

a rotating knob at the distal portion configured to:

rotate the end effector with respect to the shaft about the shaft axis when rotated; and

actuate the procedure actuator when slid in a direction towards the handle.

14. The medical device according to claim 13 , wherein the end effector is rotationally fixedly connected to the rotating knob and rotates the end effector when rotated about the shaft axis.

15. The medical device according to claim 13 , wherein:

the procedure actuator is a locking device of the end effector; and

actuation of the procedure actuator by proximal movement of the rotating knob unlocks the locking device.

16. The medical device according to claim 13 , wherein:

the pistol-shaped handle has a stapler-closing device; and

the end effector is a surgical stapling end effector having a pair of opposing stapling surfaces, at least one of the stapling surfaces being operable to move with respect to the other of the stapling surfaces upon actuation of the stapler-closing device to apply a compressive force to tissue therebetween.

17. The medical device according to claim 13 , wherein the end effector further comprises a knife assembly disposed to cut tissue at the end effector.

18. The medical device according to claim 13 , wherein the end effector comprises one of a circular surgical staple head and a linear surgical staple head.

19. The medical device according to claim 13 , wherein the rotating knob permits simultaneous rotation of the end effector and actuation of the surgical procedure actuator when rotated about the shaft axis and slid proximally.

20. The medical device according to claim 13 , wherein:

the end effector is a surgical stapling end effector having a stapling device with staples and a cutting device with a blade;

the handle has:

a stapler closing actuator closing the stapling device when actuated; and

a firing actuator that, when actuated:

staples with the stapling device; and

cuts with the cutting device; and

the stapler closing actuator and the staple firing actuator are different from the rotating knob.
