An endoscopic forceps is disclosed including an end effector assembly having two jaw members movable from a first position in spaced relation relative to one another to at least a second position closer to one another for grasping tissue therebetween. Each of the jaw members is connectable to an electrosurgical energy source for conducting energy through tissue held therebetween. The jaw members are biased to the first position. The end effector assembly of the endoscopic forceps further includes a wire snare having a proximal end connectable to an electrosurgical energy source and a distal end translatably extending out of one of the jaw members and operatively associated with the other of the jaw members. In use, withdrawal of the proximal end of the wire snare results in movement of the jaw members from the first position to a second position and clamping of the tissue between the jaws.

1. An endoscopic forceps for vessel sealing, comprising: a housing;a shaft extending from the housing and including a distal end configured and adapted to support an end effector assembly; andan end effector assembly operatively supported on the distal end of the shaft, the end effector assembly including: a pair of jaw members movable from a first position in spaced relation relative to one another to at least a second position closer to one another for grasping tissue therebetween, each of the jaw members is adapted to connect to an electrosurgical energy source such that the pair of jaw members are capable of conducting energy through tissue held therebetween to affect a tissue seal, wherein the pair of jaw members are biased to the first position; anda wire snare having a proximal end connectable to an electrosurgical energy source and a distal end translatably extending out of a distal-most tip of one of the pair of jaw members and operatively associated with the other of the pair of jaw members, wherein withdrawal of the proximal end of the wire snare results in movement of the pair of jaw members from the first position to the second position and a cinching of the wire snare. 2. The endoscopic forceps according to claim 1, wherein the pair of jaw members operate unilaterally. 3. The endoscopic forceps according to claim 2, wherein the wire snare includes an intermediate portion between the proximal end and the distal end, and wherein the distal end of the wire snare translatably extends through the other of the pair of jaw members and is secured relative to the intermediate portion of the wire snare such that longitudinal translation of the intermediate portion of the wire snare relative to the jaw members results in longitudinal translation of the distal end of the wire snare through both jaw members. 4. The endoscopic forceps according to claim 3, wherein the wire snare is fabricated from a shape-memory alloy. 5. The endoscopic forceps according to claim 4, wherein at least a portion of the shaft is flexible. 6. The endoscopic forceps according to claim 5, wherein a distal most end of the shaft is rigid. 7. The endoscopic forceps according to claim 3, wherein the intermediate portion of the wire snare includes a junction block secured thereto, the distal end of the wire snare being secured to the junction block. 8. The endoscopic forceps according to claim 1, wherein the pair of jaw members operate bilaterally. 9. The endoscopic forceps according to claim 1, wherein the end effector assembly further includes: a scissor blade operatively supported on a distal end of the shaft and movable from a first position in which the scissor blade is substantially aligned with one of said pair of jaw members and a plurality of second positions in which the scissor blade is out of alignment with the one of said pair of jaw members and extends across to the other of the pair of jaw members thereby severing tissue grasped between the pair of jaw members. 10. The endoscopic forceps according to claim 9, wherein the end effector assembly further includes: a scissor blade linkage operatively connected to the scissor blade, wherein movement of the scissor linkage results in actuation of the scissor blade between the first position and any number of the plurality of second positions. 11. An endoscopic forceps for vessel sealing, comprising: a housing;a shaft extending from the housing and including a distal end configured and adapted to support an end effector assembly; andan end effector assembly operatively supported on the distal end of the shaft, the end effector assembly including: a fixed jaw member and a movable jaw member, movable relative to the fixed jaw member, from a first position in spaced relation relative to one another to at least a second position closer to one another for grasping tissue therebetween, each of the jaw members is adapted to connect to an electrosurgical energy source such that the jaw members are capable of conducting energy through tissue held therebetween to affect a tissue seal, wherein the jaw members are biased to the first position; anda wire snare having a proximal end connectable to an electrosurgical energy source and a distal end translatably extending out of a distal-most tip of the fixed jaw and operatively associated with the movable jaw member, wherein withdrawal of the proximal end of the wire snare results in movement of the jaw members from the first position to the second position and a cinching of the wire snare. 12. The endoscopic forceps according to claim 11, wherein the wire snare includes an intermediate portion between the proximal end and the distal end, and wherein the distal end of the wire snare translatably extends through the movable jaw member and is secured relative to the intermediate portion of the wire snare such that longitudinal translation of the intermediate portion of the wire snare relative to the jaw members results in longitudinal translation of the distal end of the wire snare through both jaw members. 13. The endoscopic forceps according to claim 12, wherein the wire snare is fabricated from a shape-memory alloy. 14. The endoscopic forceps according to claim 13, wherein at least a portion of the shaft is flexible. 15. The endoscopic forceps according to claim 12, wherein the intermediate portion of the wire snare includes a junction block secured thereto, the distal end of the wire snare being secured to the junction block. 16. The endoscopic forceps according to claim 11, wherein the end effector assembly further includes: a scissor blade operatively supported on a distal end of the shaft and movable from a first position in which the scissor blade is substantially aligned with the movable jaw member and a plurality of second positions in which the scissor blade is out of alignment with the movable jaw member and extends across to the fixed jaw member thereby severing tissue grasped between the fixed and movable jaw members. 17. The endoscopic forceps according to claim 16, wherein the end effector assembly further includes: a scissor blade linkage operatively connected to the scissor blade, wherein movement of the scissor linkage results in actuation of the scissor blade between the first position and any number of the plurality of second positions. 18. An endoscopic forceps for vessel sealing, comprising: a housing;a shaft extending from the housing and including a distal end configured and adapted to support an end effector assembly, wherein at least a portion of the shaft is flexible and a distal most end of the shaft is rigid; andan end effector assembly operatively supported on the distal end of the shaft, the end effector assembly including: a pair of jaw members movable from a first position in spaced relation relative to one another to at least a second position closer to one another for grasping tissue therebetween, each of the jaw members is adapted to connect to an electrosurgical energy source such that the pair of jaw members are capable of conducting energy through tissue held therebetween to affect a tissue seal, wherein the pair of jaw members are biased to the first position, wherein the pair of jaw members operate unilaterally; anda wire snare having a proximal end connectable to an electrosurgical energy source and a distal end translatably extending out of one of the pair of jaw members and operatively associated with the other of the pair of jaw members, wherein withdrawal of the proximal end of the wire snare results in movement of the pair of jaw members from the first position to the second position and a cinching of the wire snare, wherein the wire snare is fabricated from a shape-memory alloy and the distal end of the wire snare translatably extends through the other of the pair of jaw members and is secured to itself.
