Ultrasonic surgical blade with improved cutting and coagulation features

An ultrasonic surgical blade, comprising:

• a solid body;
• a longitudinal portion having a proximal end and a distal end, the longitudinal portion comprising:
• a substantially planar longitudinal surface;
• and
• a distal hemostasis surface located opposite of the substantially planar longitudinal surface;
• a transverse portion extending crosswise from the distal end of the longitudinal portion, the transverse portion defining a hook having a free end, the transverse portion comprising:
• a curved section extending from a distal end of the substantially planar longitudinal surface;
• a tip surface defined at the free end;
• a proximal inner surface extending from the curved surface to the tip surface;
• and
• an outer convex distal surface extending from the tip surface to the distal hemostasis surface.

An ultrasonic surgical blade, comprising:

• a solid body;
• a longitudinal portion having a proximal end and a distal end, the longitudinal portion comprising:
• a sharp central ridge;
• a distal hemostasis surface located opposite of the substantially planar longitudinal surface;
• and
• an end mass located at the distal end of the longitudinal portion;
• and
• a transverse portion extending crosswise from the distal end of the longitudinal portion and located opposite of the end mass, the transverse portion defining a hook having a free end, the transverse portion comprising a tip surface defined at the free end.
