A device for performing a cesarean section, the device comprising:
- an elongate body comprising a curved anterior portion, a notch positioned proximal to the curved anterior portion, and a posterior portion, proximal to the curved anterior portion;
- a retractable blade component encased within the elongate body, the blade component comprising first and second blades, the first blade being encased within the curved anterior portion, the second blade being encased within the body, adjacent to the notch, the second blade being positionable across the notch;
- wherein the curved anterior portion is movable relative to the first blade to expose the first blade from the curved anterior portion to make an initial puncture in a uterine wall, the curved anterior portion further being moveable relative to the first blade to retract the first blade into the curved anterior portion after the initial puncture of the uterine wall to permit insertion of the curved anterior portion into the puncture, and
- wherein a bottom surface of the curved anterior portion is spaced apart from the second blade to separate the second blade from underlying tissue to prevent contact between the second blade and the underlying tissue.
