1. A surgical instrument for clamping and cutting an umbilical cord by selectively moving between a first open position, an intermediate partly closed position and a cutting position comprising:

  • scissors members comprising handles and jaws pivotally coupled together on opposite sides of a pivot member, said jaws comprising a cutting blade and means for releasably holding an integrally hinged V clamp, a V clamp comprising two spread apart arms with ratcheted inner gripping surfaces connected by an arcuate hinge section, means for locking the arms together and means for releasably securing the clamp in the jaws, characterized in that a cradle support is provided between handle and jaw near the pivot member for receiving the arcuate hinge section of the clamp, means are provided on the scissors members to push the V clamp axially forward in the jaws, and the edge of the cutting blade is positioned in the jaw above the ratcheted surface of a clamp arm, whereby, when the handles are pressed together from a first open position to an intermediate position, the jaws are closed partially, locking the arms of the V clamp while leaving the edge of the cutting blade distanced from the center of the clamp without reaching a position of cutting the cord, and whereby, when the handles are pressed further to a cutting position, the locked V clamp is pushed forward of the cradle support enabling the jaws to close completely and bring down the cutting blade to sever an umbilical cord held in the locked arms of the clamp.
