Abstract

A surgical device is disclosed including a surgical instrument and an outer sheath surrounding the surgical instrument. The surgical instruments includes an end effector including a first jaw member and a second jaw member. At least one of the first jaw member or the second jaw member is pivotable toward the other to grasp tissue. The outer sheath is slidable relative to the surgical instrument along a longitudinal axis between a first position, wherein the first jaw member and the second jaw member are positioned within the outer sheath proximal to a distal portion of the outer sheath, and a second positon, wherein the first iaw member and the second iaw member are positioned outside the outer sheath distal to the distal portion of the outer sheath. The distal portion of the outer sheath is configured to clamp tissue.

Claims

1. A surgical device, comprising:

a surgical instrument, comprising;

an end effector, including;

a first jaw member; and

a second jaw member, wherein at least one of the first jaw member or the second jaw member is pivotable toward the other to grasp tissue; and

an outer sheath surrounding the surgical instrument, wherein the outer sheath is slidable relative to the surgical instrument along a longitudinal axis between;

a first position, wherein the first jaw member and the second jaw member are positioned within the outer sheath proximal to a distal portion of the outer sheath; and

a second position, wherein the first jaw member and the second jaw member are positioned outside the outer sheath distal to the distal portion of the outer sheath;

wherein the distal portion of the outer sheath is configured to clamp tissue.

2. The surgical device of claim 1, wherein the first jaw member is configured to pivot toward the second jaw member, and wherein the second jaw member comprises an ultrasonic blade coupled to a proximally positioned transducer.

3. The surgical device of claim 1, wherein the distal portion of the outer sheath comprises a distal edge configured to treat clamped tissue.

4. The surgical device of claim 3, wherein the distal edge comprises a sharp edge to cut the clamped tissue.

5. The surgical device of claim 3, further comprising a transducer positioned to ultrasonically excite the distal edge to at least one of cut or coagulate the clamped tissue.

6. The surgical device of claim 3, wherein, in the first position, the distal portion is structured to bias upon itself.

7. The surgical device of claim 6, wherein the distal edge comprises a plurality of distal edge portions separated by longitudinal slots.

8. The surgical device of claim 1, wherein the distal portion comprises:

a first sheath jaw member; and

a second sheath jaw member, wherein the first sheath jaw member and the second sheath jaw member are transitionable between an open position in the second position and a closed position in the first position, and wherein the first sheath jaw member and the second sheath jaw member are configured to clamp the tissue in the closed position.

9. The surgical device of claim 8, wherein the surgical device further comprises a trigger, and wherein the first sheath jaw member and the second sheath jaw member are transitionable to the closed position in response to actuation of the trigger.

10. A surgical device, comprising:

a surgical instrument comprising an end effector; and

an outer sheath surrounding the surgical instrument, wherein the outer sheath is slidable relative to the surgical instrument along a longitudinal axis between;

a first position, wherein the end effector is positioned within the outer sheath proximal to a distal portion of the outer sheath; and

a second positon, wherein the end effector is positioned outside the outer sheath distal to the distal portion of the outer sheath;

wherein the distal portion of the outer sheath is configured to clamp tissue.

11. The surgical device of claim 10, wherein the end effector includes:

a first jaw member; and

a second jaw member, wherein at least one of the first jaw member or the second jaw member is pivotable toward the other to grasp tissue.

12. The surgical device of claim 10, wherein the end effector comprises an ultrasonic blade to at least one of cut or coagulate tissue.

13. The surgical device of claim 12, wherein the distal portion of the outer sheath comprises a distal edge configured to treat the clamped tissue.

14. The surgical device of claim 13, wherein the distal edge comprises a sharp edge to cut the clamped tissue.

15. The surgical device of claim 13, further comprising a transducer positioned to ultrasonically excite the distal edge to at least one of cut or coagulate the clamped tissue.

16. The surgical device of claim 12, wherein the distal portion comprises:

a first sheath jaw member; and

a second sheath jaw member, wherein the first sheath jaw member and the second sheath jaw member are transitionable between an open position in the second position and a closed position in the first position, and wherein the first sheath jaw member and the second sheath jaw member are configured to clamp the tissue in the closed position.

17. The surgical device of claim 16, wherein the surgical device further comprises a trigger, and wherein the first sheath jaw member and the second sheath jaw member are transitionable to the closed position in response to actuation of the trigger.

18. A surgical device, comprising:

a surgical instrument comprising an end effector; and

an outer sheath surrounding the surgical instrument, wherein the outer sheath is slidable relative to the surgical instrument along a longitudinal axis between;

a first position, wherein the end effector is positioned within the outer sheath proximal to a distal edge of the outer sheath; and

a second positon, wherein the end effector is positioned outside the outer sheath distal to the distal edge of the outer sheath;

wherein the distal edge is configured to clamp tissue.

19. The surgical device of claim 18, further comprising a transducer positioned to ultrasonically excite the distal edge to at least one of cut or coagulate the tissue.

20. The surgical device of claim 18, wherein the surgical instrument further comprises a transducer coupled to the end effector to at least one of cut or coagulate the tissue in the second position.

21. A surgical device, comprising:

a surgical instrument comprising an end effector; and

an outer sheath surrounding the surgical instrument, wherein the outer sheath is slidable relative to the surgical instrument along a longitudinal axis between;

a first position, wherein the end effector is positioned outside the outer sheath; and

a second positon, wherein the end effector is positioned within the outer sheath;

wherein a distal portion of the outer sheath is configured to clamp tissue.
