  • Patent number: 5417683
    Abstract: A mini-graft hair implanting device for implanting multiple clumps of hair follicles at one time includes a barrel, a plunger and a depth control unit. The barrel is formed as a hollow cylinder with an open top and a bottom wall that has a cluster of hollow needles which are attached thereto so as to extend downwardly therefrom. Each of the hollow needles is adapted to receive a clump of hair follicles therein and has two open ends, a distal one of which is tapered so as to form a pointed tip. The plunger extends slidably into the barrel and has a bottom end that is formed with a set of downwardly extending first push rods and at least one downwardly extending second push rod. The first push rods are aligned with and extend into the hollow needles. The depth control unit is attached to and extends downwardly from the bottom wall of the barrel. The depth control unit includes at least one tube which is shorter than the hollow needles and which has two open ends, a distal one of which is blunt.
