Electrosurgical forceps

An electrosurgical forceps, comprising:

• first and second shaft members;
• first and second jaw members extending distally from the respective first and second shaft members, each of the first and second jaw members defining a longitudinal axis and a curved distal section curving off of the longitudinal axis, the curved distal section of each of the first and second jaw members defining a width at the proximal end thereof, the curved distal section of each of the first and second jaw members including a distal tip portion defined as an area within a concave side of a curved distal perimeter of the distal tip portion, the distal tip portion of each of the first and second jaw members defining a diameter transversely thereacross;
• and
• a pivot coupling 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, and
• wherein a ratio of the width of the proximal end of the curved distal section of each of the first and second jaw members to the width of the diameter of the distal tip portion of each of the first and second jaw members is in a range of from about 1.60 to about 2.00, and
• wherein at least one of the first or second jaw members defines a stiffness from about 80 lb/in to about 300 lb/in.

An electrosurgical forceps, comprising:

• first and second shaft members;
• first and second jaw members extending distally from the respective first and second shaft members, each of the first and second jaw members including an opposed, inwardly-facing side having a proximal end and a distal tip portion defined as an area within a concave side of a curved distal perimeter of the distal tip portion;
• and
• a pivot coupling 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,
• a ratio of a height of the first and second jaw members at the proximal ends of the inwardly-facing sides of the first and second jaw members to a height of the first and second jaw members at the distal tip portions of the first and second jaw members is in a range of about 1.80 to about 2.10, and
• wherein at least one of the first or second jaw members defines a stiffness from about 80 lb/in to about 300 lb/in.
