Disposable vascular occluder

摘要

A disposable vascular occluding device for temporarily stopping or interrupting blood flow in veins or arteries of the body during vascular surgery and emergency trauma surgery is constructed with two plastic arms connected at one end by a hinge for pivoting the arms towards and away from each other and connected at an end opposite the hinged end by a toothed latch for releasably securing the plastic arms in a closed position with inner surfaces thereof confronting each other. The inner surfaces of the plastics arms have semi-circular cavities formed therein which are shaped to conform to the blood vessel to be occluded. The inner surfaces of the plastic arms are lined by a pair of partially-inflated soft plastic balloons, centered in the cavities, one of which is further inflatable by means of an ordinary syringe through a valve in one of the plastic arms. The device facilitates occlusion of a blood vessel with minimal or no traumatization of the wall of the blood vessel.
