ABSTRACT:
A multiple bladed surgical knife for removing donor strips of hair-laden scalp tissue from a donor for hair graft transplantation to a donor. The knife includes a plurality of blades which are spaced apart by a plurality of spacers. The blades may advantageously shift longitudinally with respect to each other at a surgeon's discretion such that donor strips of consistent depth are obtained. In addition, the number of hair follicles which are destroyed during the removal process is minimized. In one embodiment of the present invention, the blade penetration depth is controlled via selectively sizing and shifting the plurality of spacers. In one particular embodiment, the blades and spacers may be shifted with the assistance of a pin, and in another embodiment, the knife includes a plurality of markings indicating a particular blade angle.
