摘要： A knife configured for use with an electrosurgical forceps having curved jaw members and a method of manufacturing the same. The knife includes a distal body having an inner side and an outer side, a first etching on the outer side of the distal body defining a distal cutting edge and a second etching on the outer side of the distal body extending along a portion of a length of the distal body to define relatively protruded and relatively recessed surfaces extending along a portion of the length of the distal body on the outer side thereof.

摘要： A forceps includes first and second shafts each having a jaw disposed at a distal end thereof configured to rotate about a pivot to move the jaws between open and closed positions, the shafts defining a longitudinal axis therebetween. A knife deployment mechanism including a rack and pinion mechanism or a series of links is disposed within the first shaft and includes a trigger moveable along the longitudinal axis to deploy a knife between the jaws. A knife lockout is configured to move upon approximation of the first and second shafts between an engaged position preventing deployment of the knife and a disengaged position allowing deployment of the knife. A knife kickout mechanism is disposed within the first shaft in opposition to the second shaft and is configured to force the knife forward upon movement of the first and second shafts from an approximated position to a more open position.

摘要： An end effector of an electrosurgical forceps includes a first jaw member, a second jaw member, and a cap. The first jaw member has a pivot pin extending inwardly from an inner lateral side thereof. The second jaw member is pivotably coupled to the pivot pin. The cap couples the first and second jaw members to one another.

摘要： An electrosurgical forceps includes first and second shaft members and first and second jaw members extending distally from the respective first and second shaft members. A pivot couples the first and second shaft members with one another such that the first and second shaft members are movable relative to one another between a spaced-apart position and an approximated position to move the first and second jaw members relative to one another between an open position and a closed position. The jaw members are configured to facilitate tissue treatment, tissue division, and blunt tissue dissection.

摘要： An electrosurgical forceps includes first and second shaft members pivotably coupled to one another via a pivot member such that pivoting of the first and second shaft members between spaced-apart and approximated positions pivots jaw members thereof between open and closed positions. A knife is translatable between retracted and extended positions. A knife deployment mechanism is operably coupled to the first shaft member and includes at least one trigger and at least one linkage coupling the at least one trigger with the knife such that pivoting of the at least one trigger relative to the first shaft member translates the knife between the retracted and extended positions. A knife lockout biased towards a locked position inhibits distal translation of the knife. The knife lockout is movable from the locked position to an unlocked position upon approximation of the jaw members to permit distal translation of the knife.

摘要： An electrosurgical forceps includes first and second shaft members pivotably coupled to one another via a pivot member such that pivoting of the first and second shaft members between spaced-apart and approximated positions pivots jaw members thereof between open and closed positions. A knife is translatable between retracted and extended positions. The knife has a stop to prevent distal movement of the knife beyond the extended position.
