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 ### Claim 1 A surgical forceps, comprising: an elongated shaft having a proximal portion and a distal portion; an end effector coupled to the distal portion of the elongated shaft, the 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 movable relative to the other jaw member between a spaced-apart position and an approximated position for grasping tissue therebetween; and a tube extending within or along the elongated shaft and movable relative to the end effector between a first position and a second position, the tube is configured to apply at least one of suction or irrigation proximately of the end effector. ### Claim 2 (depends on 1) The surgical forceps according to claim 1, wherein each of the first jaw member and the second jaw member includes an electrically-conductive tissue-contacting surface configured to connect to a source of energy to apply energy to the tissue. ### Claim 3 (depends on 1) The surgical forceps according to claim 1, further comprising an actuator disposed in the elongated shaft and operably coupled to the tube, the actuator slidable between an unactuated position and an actuated position to slide the tube between the first position and the second position. ### Claim 4 (depends on 1) The surgical forceps according to claim 1, wherein in the second position, a distal portion of the tube is distal of the end effector. ### Claim 5 A surgical system comprising: a surgical forceps including: an elongated shaft having a proximal portion and a distal portion; an end effector coupled to the distal portion of the elongated shaft; and a tube extending within or along the elongated shaft and movable relative to the end effector between a first position and a second position; a low pressure source coupled to the tube, the low pressure source configured to provide suction through the tube; and a fluid source coupled to the tube, the fluid source configured to provide irrigation fluid through the tube. ### Claim 6 (depends on 5) The surgical system according to claim 5, 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 movable relative to the other jaw member between a spaced-apart position and an approximated position for grasping tissue therebetween. ### Claim 7 (depends on 6) The surgical system according to claim 6, wherein each of the first jaw member and the second jaw member includes an electrically-conductive tissue-contacting surface. ### Claim 8 (depends on 7) The surgical system according to claim 7, further comprising: an electrosurgical generator coupled to the electrically-conductive tissue-contacting surfaces and configured to apply energy to the tissue. ### Claim 9 (depends on 5) The surgical system according to claim 5, further comprising an actuator disposed in the elongated shaft and operably coupled to the tube, the actuator slidable between an unactuated position and an actuated position to slide the tube between the first position and the second position. ### Claim 10 (depends on 5) The surgical system according to claim 5, wherein in the second position, a distal portion of the tube is distal of the end effector. ### Claim 11 (depends on 5) The surgical system according to claim 5, further comprising an actuator configured to slide the tube between the first position and the second position via at least one of a button, a handle, a mechanical deployment system, an electro-mechanical deployment system, a lever, or a slide. ### Claim 12 A surgical forceps, comprising: an elongated shaft having a proximal portion and a distal portion; an end effector coupled to the distal portion of the elongated shaft; a tube extending within or along the elongated shaft and movable relative to the end effector between a first position and a second position, the tube is configured to apply at least one of suction or irrigation proximately of the end effector; and an actuator disposed in the elongated shaft and operably coupled to the tube, the actuator slidable between an unactuated position and an actuated position to slide the tube between the first position and the second position. ### Claim 13 A surgical forceps, comprising: an elongated shaft having a proximal portion and a distal portion; an end effector coupled to the distal portion of the elongated shaft; and a tube extending within or along the elongated shaft and movable relative to the end effector between a first position and a second position, the tube is configured to apply at least one of suction or irrigation proximately of the end effector, wherein in the second position, a distal portion of the tube is distal of the end effector. ### Claim 14 A surgical system comprising: a surgical forceps including: an elongated shaft having a proximal portion and a distal portion; an end effector coupled to the distal portion of the elongated shaft, the 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 movable relative to the other jaw member between a spaced-apart position and an approximated position for grasping tissue therebetween; and a tube extending within or along the elongated shaft and movable relative to the end effector between a first position and a second position; and a low pressure source coupled to the tube, the low pressure source configured to provide suction through the tube. ### Claim 15 A surgical system comprising: a surgical forceps including: an elongated shaft having a proximal portion and a distal portion;
