Abstract
In performing cesarean section (c/section) surgery, and other surgery, a scalpel blade is used having a blunt and rounded edge to divide or separate tissue. In a cesarean section a scalpel with a sharp edge is first used to begin the uterine incision. A scalpel blade with a blunt and rounded edge is then used to continue the incision through the uterine wall to the amniotic cavity. The blunt edge scalpel blade reduces the possibility of lacerating the baby during delivery.

5. The method of performing a cesarean section to deliver a baby including the steps, in sequence, of:
-
(i) cutting an incision through the abdominal wall using a scalpel having a blade with a sharp edge which is sufficiently sharp to cut normal skin; (ii) using a scalpel having a blade with a sharp edge to cut a shallow and elongated incision in the thin outer layer of the uterus at a depth of less than the thickness of the uterus; (iii) using a scalpel having a blade with a blunt edge which is sufficiently non-sharp so that it will not cut normal skin to sever the uterus wall with the blunt edge, the severing being along the shallow incision formed in (ii), the blunt edge blade not having a sharp edge, and thereby forming an opening through which the baby may be delivered. - View Dependent Claims (6, 7, 8, 9)
