  • Patent number: 4217902
    Abstract: This is a hemostatic clip for clasping the flaps of a wound together and holding them together to prevent bleeding and to promote healing until the wound is healed and in closed position, whereupon it is released. It is made in a generally tubular body form with a longitudinal slit having cooperating teeth on the slit edges. It is made of a suitable resilient metal or plastic material. Opposite the elongate slit, the tubular body is provided with an inwardly extending longitudinal U-shape depression which, when pressure is applied to the sides of the U, will cause the slit and teeth to separate, whereby it can be applied to the wound flaps. When the pressure is released, the teeth will grasp and hold the wound flaps in contact. When the wound has healed sufficiently, the pressure is again applied to release the teeth from engagement with the flaps. Ridges, eyelets or apertures are provided in the tubular body to cooperate with a pair of plyers for applying suitable pressure.
