Flexible Endoscopic Catheter with Ligasure
First Claim
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; and
an 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; and
a 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.

Abstract
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.

10. 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; an end effector assembly operatively supported on the distal end of the shaft, the end effector assembly including; a cutting blade supported on the distal end of the shaft, the cutting blade including a cutting edge extending in a distal direction; a movable jaw member translatably supported on the shaft, the movable jaw member including a tissue contacting portion extending across a longitudinal axis of the shaft; and an anvil member slidably supported on the movable jaw member between the tissue contacting portion of the movable jaw member and the cutting blade, the anvil member defining a blade slot formed therein for selectively receiving the cutting blade therethrough; and a movable handle operatively associated with the housing, wherein actuation of the movable handle relative to the housing results in movement of the movable jaw member relative to the shaft. - View Dependent Claims (11, 12)

13. 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; and an 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; and a wire snare having a proximal end connectable to an electrosurgical energy source and a distal end translatably extending out 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. - View Dependent Claims (14, 15, 16, 17, 18)
