Abstract
A surgical clamp for clamping a blood vessel and preferably made of a single piece of plastic material is provided with a hinge element flexibly connecting one end each of an upper and lower clamping arm at a spaced distance. The other end of one of the clamping arms has a locking pawl flexibly connected thereto. A mating locking mechanism flexibly connected to the other of the clamping arms engages a latch pin on the locking pawl when the clamping arms are brought together. The four hinge points, including the point of juncture between latch pin and the locking mechanism, are arrayed in a parallelogram configuration which provides for parallel movement and automatic self adjustment of the distance between the clamping arms as the clamping arms are brought together to clamp the blood vessel. Combined flexible wall andlocking mechanism elements prevent the blood vessel from being dislodged after the clamping operation, and provide ease of application of the clamp to the blood vessel.
