The No.11 is an elongated triangular blade sharpened along the beveled edge with a strong tip, ideal for puncturing abscesses or stabbing wounds required when inserting a chest drain.
It is held like a pencil and is often held upside down by surgeons to prevent it from being inadvertently inserted too deep. To avoid this, the scalpel should not be placed on the back end, but the heel of the hand should be placed on the skin, stabilizing the hand to help prevent unnecessary deep cuts.
No. 11 is also used for other small incisions, such as the ankle during insertion of laparoscopic ports, venous and arterial centerlines, opening of the aorta and removal of calcifications in the aorta or mitral valve, anatomy, and surgical treatment of foot disorders and lower extremities in podiatry.
Size 11 blades fit handle 3, 3L, 3 gradient, 5B, 7, 9 and B3.+9
