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.

La seconde portion de lame est plus flexible que la première et la troisième. Un second instrument médical à ultrasons comprend une lame ultrasonique médicale comportant une portion de lame proximale et une portion de lame distale. La portion de lame distale se plie plus facilement que la portion de lame proximale. La portion de lame distale comprend une extrémité distale conçue pour entrer en contact et traiter de manière ultrasonique les tissus du patient. Un troisième instrument médical à ultrasons comprend une lame ultrasonique médicale. Cette lame ultrasonique médicale comprend une portion de lame proximale ayant une ligne centrale et comprend une portion de lame distale en contact avec la portion de lame proximale au niveau d'une interface substantiellement plane. Cette interface est orientée à un angle non nul par rapport à une perpendiculaire à la ligne centrale au niveau de l~interface.
