ABSTRACT:
A device for rapid reattachment of a bone flap to a cranium after a surgical operation is provided. The device comprises a pin comprising an elongated shaft, an inner disk and an outer disk. At least the outer disk comprises a central bore. The pin and inner disk are adapted to be assembled together to form a pin and inner disk assembly such that the inner disk is located at one end of the pin. The outer disk is adapted to be mounted on the shaft of the pin with the shaft of the pin extending through the central bore of the outer disk. The device is operated by (i) positioning the inner disk on the inside of the cranium with the shaft of the pin extending through the kerf between the bone flap and the cranium, (ii) forcing the outer disk downwardly on the shaft of the pin toward the inner disk until the outer disk securely engages the outside of the bone flap and the cranium, such that the bone flap is securely held in place between the inner disk and the outer disk, and (iii) trimming off an excess portion of the shaft extending out beyond the outer disk.
