Optical sealing device with cutting ability
First Claim
1. A forceps, comprising:
- an end effector assembly including first and second jaw members, at least one of the jaw members movable relative to the other between a spaced-apart position, a first approximated position wherein the jaw members define a first gap distance “
G”
therebetween configured to apply a first pressure to tissue clamped between the jaw members, and a second approximated position wherein the jaw members define a second gap distance “
g”
therebetween configured to apply a second pressure greater than the first pressure to tissue clamped between the jaw members, at least one of the jaw members adapted to connect to a source of energy;
a handle assembly including a movable handle operably coupled to the end effector, the movable handle movable between an initial stage, a first actuated stage, and a second actuated stage for moving the jaw members between the spaced-apart position, the first approximated position, and the second approximated position;
a first switch assembly selectively activatable to supply a first light energy to at least one jaw member to seal tissue grasped between the jaw members when the jaw members are disposed in the first approximated position; and
a second switch assembly selectively activatable to supply a second light energy to the at least one jaw member to cut tissue grasped between the jaw members when the jaw members are disposed in the second approximated position, wherein each of the second pressure and the second light energy is individually insufficient to cut the tissue.

Abstract
A forceps includes an end effector assembly, a handle assembly, a first switch assembly, and a second switch assembly. The end effector includes first and second jaw members, at least one of the jaw members movable relative to the other between a spaced-apart position, a first approximated position and a second approximated position, at least one of the jaw members adapted to connect to a source of energy. The handle assembly includes a movable handle operably coupled to the end effector, and is movable between an initial stage, a first actuated stage, and a second actuated stage. The first switch assembly is activatable to supply a first energy to the end effector to seal tissue grasped, and the second switch assembly is activatable to supply a second energy to the end effector to cut tissue grasped.
