Abstract

The present disclosure is directed to a forceps having an end effector assembly including first and second jaw members. At least one of the jaw members is movable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. Each jaw member includes an electrically-conductive tissue-contacting surface adapted to connect to a source of energy to treat tissue grasped between the jaw members. A suction system is disposed proximate the first and second jaw members and is configured to apply suction to a surgical site upon activation thereof.

Claims

1. A forceps, comprising:

a first elongated shaft having a first proximal portion and a first distal portion;

a second elongated shaft having a second proximal portion and a second distal portion;

a first jaw member secured to and extending from the first distal portion;

a second jaw member secured to and extending from the second distal portion, the first and second jaw members moveable about a pivot between an open position in which the first and second jaw members are spaced-apart from one another and a closed position in which the first and second jaw members cooperate to grasp tissue therebetween; and

a tube extending from the first proximal portion to the first distal portion and including a distal tube segment, the distal tube segment slidable relative to the first and second jaw members between a retracted position relative to the first and second jaw members and a deployed position relative to the first and second jaw members distal of the retracted position.

2. The forceps according to claim 1, wherein the tube is configured to apply suction proximate the first and second jaw members.

3. The forceps according to claim 1, wherein the tube is configured to apply irrigation proximate the first and second jaw members.

4. The forceps according to claim 1, wherein a segment of the tube is disposed within the first elongated shaft.

5. The forceps according to claim 1, further comprising an actuator disposed on the first elongated shaft and operably coupled to the tube, the actuator slidable from an unactuated position to an actuated position to slide the distal tube segment from the retracted position to the deployed position.

6. The forceps according to claim 1, wherein in the deployed position, the distal tube segment is distal of the first and second jaw members.

7. The forceps according to claim 1, wherein each of the first and second jaw members includes an electrically-conductive tissue-contacting surface adapted to connect to a source of energy to treat tissue grasped between the first and second jaw members.

8. A forceps, comprising:

a first shaft having a distal portion;

an end effector assembly supported on the distal portion of the first shaft and including first and second jaw members pivotable relative to one another between a spaced-apart position and an approximated position for grasping tissue therebetween;

a tube extending along the distal portion of the first shaft and including a distal tube segment, the distal tube segment slidable relative to the first and second jaw members between a retracted position relative to the first and second jaw members and a deployed position relative to the first and second jaw members distal of the retracted position.

9. The forceps according to claim 8, wherein the tube is configured to apply suction proximate the first and second jaw members.

10. The forceps according to claim 8, further comprising a first handle secured to a proximal portion of the first shaft and a second handle secured to a proximal portion of a second shaft, wherein the first jaw member is secured to the distal portion of the first shaft and the second jaw member secured to a distal portion of the second shaft, the first and second handles movable towards and away from one another to pivot the first and second jaw members between the spaced-apart and approximated positions.

11. The forceps according to claim 10, wherein the tube is connected to a suction tube deployment device that is operably connected to the first handle.

12. The forceps according to claim 8, further comprising a housing having a fixed handle and a movable handle, the first shaft extending from the housing, the moveable handle movable towards the fixed handle to pivot the first and second jaw members towards the approximated position.

13. The forceps according to claim 12, wherein the first shaft defines a longitudinal axis of the forceps that passes between the first and second jaw members.

14. The forceps according to claim 12, wherein the tube is connected to a suction tube deployment device that is operably connected to the housing.

15. The forceps according to claim 8, wherein each of the first and second jaw members includes an electrically-conductive tissue-contacting surface adapted to connect to a source of energy to treat tissue grasped between the first and second jaw members.

16. The forceps according to claim 8, wherein a segment of the tube is disposed within the first shaft.

17. The forceps according to claim 8, further comprising an actuator configured to slide the distal tube segment between the retracted position and the deployed position via at least one of a button, a handle, a mechanical deployment system, an electro-mechanical deployment system, a lever, or a slide.
