  • Patent number: 4192315
    Abstract: This disclosure relates to a clip for surgical purposes comprising a coil spring having at least one loop and a pair of crossing legs. The ends of the legs which extend beyond the crossing point are formed as clamping jaws. Because the portions of the legs adjoining the loop extend generally parallel to one another and the ends of the legs run side-by-side, and because a ring is provided at the crossing point for holding the legs together, the clip can be constructed with such small dimensions that it is particularly advantageously useful for neurosurgical purposes.
