Ultrasound medical instrument having a medical ultrasonic blade
First Claim
1. An ultrasound medical instrument comprising:
- a medical ultrasonic blade having a length and including first, second and third blade portions, wherein the second blade portion is disposed lengthwise between the first and third blade portions and includes at least two longitudinal vibration nodes thereon, wherein the first blade portion is disposed proximal the second blade portion, wherein the third blade portion is disposed distal the second blade portion, wherein the first blade portion has a first transverse area, the second blade portion has a second transverse area and the third blade portion has a third transverse area, the first and third transverse areas each being greater than the second transverse area, and wherein the second blade portion is more bendable than either of the first and third blade portions; and
a user-actuated articulated sheath received over the medical ultrasonic blade.

Abstract
A first ultrasound medical instrument includes a medical ultrasonic blade having first, second and third blade portions. The second blade portion is more bendable than either of the first and third blade portions. A second ultrasound medical instrument includes a medical ultrasonic blade having a proximal blade portion and a distal blade portion. The distal blade portion bends more easily than does the proximal blade portion. The distal blade portion includes a distal end portion adapted to contact and ultrasonically treat patient tissue. A third ultrasonic medical instrument includes a medical ultrasonic blade. The medical ultrasonic blade includes a proximal blade portion having a centerline and includes a distal blade portion in contact with the proximal blade portion at a substantially planar interface. The interface is oriented at a non-zero angle with respect to a perpendicular to the centerline at the interface.

16. An ultrasound medical instrument comprising:
-
a medical ultrasonic blade having a length and including first, second and third blade portions, each of the first, second and third blade portions including at least one longitudinal vibration node, wherein the second blade portion is disposed lengthwise between the first and third blade portions, wherein the first blade portion is disposed proximal the second blade portion, wherein the third blade portion is disposed distal the second blade portion, wherein the first blade portion has a first transverse area, the second blade portion has a second transverse area and the third blade portion has a third transverse area, the first and third transverse areas each being greater than the second transverse area, and wherein the second blade portion is more bendable than either of the first and third blade portions; and a user-actuated articulated sheath received over the medical ultrasonic blade, the sheath including a rigid first sheath portion contacting the longitudinal vibration node of the first blade portion, a flexible second sheath portion contacting the longitudinal vibration node of the second portion, and a rigid third sheath portion contacting the longitudinal vibration node of the third portion. - View Dependent Claims (17)
