Ultrasonic device for cutting and coagulating

A method of transecting tissue, the method comprising:

• obtaining a surgical cutting and coagulating scissors, the scissors comprising:
• a first body member having a proximal end and a distal end defining a body plane, wherein a portion of the first body member is plastic;
• a first finger ring located on the first body member's proximal end, the first finger ring having a pliable inner surface;
• a first jaw member located adjacent the first body member's distal end angled away from the body plane, wherein a portion of the jaw member is metallic;
• a second body member having a proximal end and a distal end located substantially in the body plane, wherein a portion of the second body member is plastic;
• a second finger ring located on the second body member's proximal end, the second finger ring having a pliable inner surface;
• a second jaw member located adjacent the second body member's distal end angled in the same direction as the first jaw member, wherein a portion of the jaw member is metallic;
• a pivot located adjacent to the first and second jaw members joining the first and second body members thereby allowing the first body member and the second body member to move relative to one another in the body plane;
• a switch located on the first body member oriented for activation in the body plane for selectively applying energy to at least one of the first or second jaw members;
• clamping the first and second jaw on tissue;
• activating the switch by applying a force in a direction parallel to the body plane thereby applying energy to the tissue;
• and
• transecting the tissue between the jaws while the first and second jaws remain in the clamped position.

• a second jaw member located adjacent the second body member's distal end;
• a pivot located adjacent to the first and second jaw members joining the first and second body members thereby allowing the first body member and the second body member to move relative to one another wherein the relative motion of the first and second body members defines a plane of motion;
• and
• a switch for applying energy to at least one of the first or second jaw members located on the first body member oriented for activation in the plane of motion.

A method of transecting tissue, the method comprising:

• obtaining a surgical cutting and coagulating scissors, the scissors comprising:
• a first body member having a proximal end and a distal end defining a longitudinal axis, wherein the first body member's proximal end is comprised of plastic and the first body member's distal end is comprised of metal;
• a first finger ring located on the first body member's proximal end, the first finger ring having a pliable inner surface;
• a first jaw member located adjacent the first body member's distal end angled away from the longitudinal axis, wherein a portion of the jaw member is metallic;
• a second body member having a proximal end and a distal end, wherein the second body member's proximal end is comprised of plastic and the second body member's distal end is comprised of metal;
• a second finger ring located on the second body member's proximal end, the second finger ring having a pliable inner surface;
• a second jaw member located adjacent the second body member's distal end angled in the same direction as the first jaw member, wherein a portion of the second jaw member is metallic;
• a pivot located in the distal metallic portions of the first and the second body members joining the first and second body members thereby allowing the first body member and the second body member to move relative to one another wherein the relative motion of the first and second body members defines a plane of motion, wherein the plane of motion passes through the longitudinal axis;
• a switch located on the first body member oriented for activation in the plane of motion for selectively applying energy to at least one of the first or second jaw members;
