Claim:
A surgical scalpel configured to perform a C-section on a patient with a uterus outer wall having a uterus surface, said scalpel comprising: an elongated flat body shaped to fit comfortably in the hand of a surgeon and having two opposed flat surfaces defining generally a thickness for the body, two opposed longitudinal edges including a top longitudinal body edge extending along a top tangential line and a bottom longitudinal body edge, said longitudinal body edges having respective first and second ends, a round end joining the first ends of said longitudinal body edges, and a notch disposed at the second ends of said longitudinal body edges, said notch being formed between an extension, a beak and a cutting blade spanning said extension and said beak; said extension having a top extension edge formed by the second end of said top body edge and an extension lower edge extending downwardly at an acute angle from said top longitudinal edge; said beak terminating in a piercing point extending further then said extension, said beak having a top beak edge extending linearly backwardly to said extension lower edge, and a lower beak edge with a curved shape extending from said piercing point to the end of said lower body edge, said top beak edge being disposed at an angle of about 35-40 degrees with respect to said top tangential line; said body being configured to be positioned by the surgeon successively to three positions during a C-section procedure including: a) a first position for piercing the uterus outer wall with said piercing point, in said first position, said body being positioned with said top tangential line is disposed at an angle of about 75-80 degrees with respect to the outer wall of the uterus, in said first position, said body being configured to pierce the outer wall of the uterus with said piercing point of said beak; b) a second position for starting to make an incision in the uterus wall, in said second position, the body being positioned with the beak disposed under the uterus wall with beak upper edge disposed in parallel with the uterus surface and the tangential wall being disposed at an angle of about 35-40 degrees with respect to the uterus surface and said top beak edge; and c) a third position in which the piercing point is pushing the uterus wall upward to direct to position it for a clean cut as the body is moved in said third position along the uterus surface, with the top tangential wall being disposed at an angle of about 15-25 degrees with respect to a bottom tangential line, said bottom tangential line being tangential to said beak bottom surface and parallel to the uterus wall.
