Document Type and Number:
Japanese Patent JP2001522685
Kind Code:
A
Abstract:
A laparoscopic bipolar electrosurgical instrument for sealing tissue includes a handle having an elongated tube affixed thereto. The tube includes first and second jaw members having electrically conductive sealing surfaces attached to a distal end thereof which are movable from a first position for approximating tissue to a second position for grasping tissue therebetween. The handle includes a fixed handle and a handle which is movable relative to the fixed handle to effect movement of the jaw members from the first position to the second position for grasping tissue. The jaw members connect to a source of electrosurgical energy such that the opposable sealing surfaces are capable of conducting electrosurgical energy through tissue held therebetween. A stop is included for maintaining a minimum separation distance between opposing sealing surfaces. A ratchet is also included to maintain a closure force in the range of about 7 kg/cm2 to about 13 kg/cm2 between opposing sealing surfaces.
