Ultrasonic surgical instrument, shears and tissue pad, method for sealing a blood vessel and method for transecting patient tissue
First Claim
1. An ultrasonic surgical shears comprising:
- a) a bifurcated ultrasonic surgical blade having a first distal tip portion and a second distal tip portion transversely spaced apart from the first distal tip portion creating a space therebetween;
b) a clamping arm operable to open and close toward the blade to define a clamped position and an unclamped position; and
c) a substantially “
T”
-shaped tissue pad attached to the clamping arm and having first and second arms and a foot each having a clamping surface, wherein, in the clamped position, the clamping surface of the first arm faces substantially toward the first distal tip portion, the clamping surface of the second arm faces substantially toward the second distal tip portion, and the clamping surface of the foot faces substantially toward the space between the first and second distal tip portions.

Abstract
An ultrasonic surgical shears has a bifurcated ultrasonic surgical blade, a clamping arm and a substantially “T”-shaped tissue pad. An alternate ultrasonic surgical shears has an ultrasonic surgical blade, a clamping arm, and a tissue pad having first and second transverse outer portions and a movable transverse central portion. An ultrasonic surgical instrument has an ultrasonic surgical clamp including an ultrasonic member adapted to ultrasonically vibrate and has a surgical cutter distinct from the ultrasonic member. A method for sealing a blood vessel of a patient includes obtaining an ultrasonic surgical clamp, sealing the blood vessel with the ultrasonic member, and transecting the sealed blood vessel using the surgical cutter. An alternate method similarly transects patient tissue and seals a blood vessel therein. An ultrasonic-surgical-shears tissue pad includes first and second transverse outer portions which are more resiliently flexible than is a transverse central portion.

8. A method for sealing a blood vessel of a patient comprising the steps of:
-
a) obtaining an ultrasonic surgical clamp including an ultrasonic member, a clamping arm operable to open and close toward the ultrasonic member, and a tissue pad attached to the clamping arm and having a clamping surface;
b) disposing the blood vessel between the ultrasonic member and the clamping surface;
c) operating the clamping arm to clamp the blood vessel between the ultrasonic member and the clamping surface and ultrasonically vibrating the ultrasonic member to seal but not transect the blood vessel;
d) obtaining a surgical cutter distinct from the ultrasonic member; and
e) transecting the sealed blood vessel using the surgical cutter. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method for transecting patient tissue and sealing a blood vessel therein comprising the steps of:
-
a) obtaining an ultrasonic surgical clamp including an ultrasonic member, a clamping arm operable to open and close toward the ultrasonic member, and a tissue pad attached to the clamping arm and having a clamping surface;
b) disposing the patient tissue between the ultrasonic member and the clamping surface;
c) operating the clamping arm to clamp the patient tissue between the ultrasonic member and the clamping surface and ultrasonically vibrating the ultrasonic member to seal the blood vessel but not transect the patient tissue including the blood vessel;
d) obtaining a surgical cutter distinct from the ultrasonic member; and
e) transecting the patient tissue including the sealed blood vessel using the surgical cutter.

17. An ultrasonic surgical instrument comprising:
-
a) an ultrasonic surgical clamp including an ultrasonic member, a clamping arm operable to open and close toward the ultrasonic member, and a tissue pad attached to the clamping arm and having a clamping surface, wherein the ultrasonic surgical clamp is adapted to ultrasonically seal a blood vessel clamped between the clamping surface of the tissue pad and the ultrasonic member by ultrasonically vibrating the ultrasonic member; and
b) a surgical cutter distinct from the ultrasonic member, connected to the ultrasonic surgical clamp, and adapted to transect a blood vessel which has been sealed by the ultrasonic surgical clamp. - View Dependent Claims (18, 19, 20)

b) a clamping arm operable to open and close toward the blade to define a clamped position and an unclamped position; and
c) a tissue pad attached to the clamping arm and having first and second transverse outer portions and a transverse central portion disposed between the first and second transverse outer portions, wherein the transverse central portion is movable, with respect to the first and second transverse outer portions, toward the blade. - View Dependent Claims (22, 23, 24, 25)

- 26. An ultrasonic-surgical-shears tissue pad comprising an ultrasonic-surgical-shears tissue pad body having a top surface attachable to a clamping arm of an ultrasonic surgical shears, having a bottom surface including a clamping surface, having a clamping direction, having first and second transverse outer portions each extending from the top to the bottom surface, and having a transverse central portion disposed between the first and second transverse outer portions and extending from the top to the bottom surface, wherein the first and second transverse outer portions are more resiliently flexible along the clamping direction than is the transverse central portion.
