1. An apparatus comprising: a main body comprising a first bore disposed between first and second ends of said main body;a nipple portion comprising a first end portion coupled to said first end of said main body and a tip portion, the nipple portion comprising a second bore disposed within said tip
1. An apparatus comprising: a main body comprising a first bore disposed between first and second ends of said main body;a nipple portion comprising a first end portion coupled to said first end of said main body and a tip portion, the nipple portion comprising a second bore disposed within said tip portion;a punch, having an interior surface, for extracting one or more hair follicles along said interior surface of said punch, said punch comprising a first punch end and a second punch end and having a substantially cylindrical shape slidably disposed within said second bore, and wherein said punch comprises a substantially uniform cylindrical cutting edge positioned substantially perpendicular to an axis extending between said first and second ends of said punch;an actuator in direct communication with said first end of said punch to displace said punch along an axis of said second bore, in response to adjustment of said actuator, to fix a distance by which said second punch end portion extends beyond said tip portion of said nipple portion; anda stabilizer disposed within said main body between said nipple portion and said actuator, wherein said punch extends through a bore of said stabilizer, said stabilizer having an outer surface, a substantially full length of said outer surface being in direct communication with an interior surface of said main body. 2. The apparatus of claim 1, wherein displacement of said actuator along said axis is controlled by rotation of said actuator about said axis. 3. The apparatus of claim 2, wherein said displacement of said actuator along said axis is capable of changing substantially proportionally with respect to said rotation. 4. The apparatus of claim 1, wherein said second end of said punch comprises a flat end or an angled end. 5. The apparatus of claim 1, wherein said punch is translatable along said axis in response to rotation of said actuator. 6. The apparatus of claim 1, wherein said nipple portion further comprises an inner surface and wherein said second end of said punch is in communication with at least a portion of said inner surface of said nipple portion. 7. The apparatus of claim 2, wherein displacement of said punch along said axis is adjustable in a range between 0 and 8 mm in response to rotation of said actuator. 8. The apparatus of claim 1, wherein said actuator further comprises a head portion having at least one first depth indicator. 9. The apparatus of claim 8, wherein said first end of said main body further comprises at least one second depth indicator capable of alignment with said first depth indicator. 10. The apparatus of claim 1, wherein a first diameter of said first end of said punch is greater than a second diameter said second end of said punch. 11. The apparatus of claim 1, wherein said main body further comprises a visible graduated scale. 12. The apparatus of claim 10, wherein said actuator further comprises an indicator capable of aligning with a graduated scale. 13. The apparatus of claim 1, wherein said tip portion further comprises a lip portion capable of contacting skin of a patient. 14. The apparatus of claim 13, wherein said lip portion limits the depth of penetration of said punch into the skin of a patient. 15. The apparatus of claim 13, wherein the second end of the punch extends beyond the lip portion a predetermined length. 16. The apparatus of claim 1, wherein displacement of said actuator along said axis is controllable in response to a mechanical force acting on said actuator. 17. The apparatus of claim 1, wherein displacement of said actuator along said axis is controllable in response to a hydraulic force acting on said actuator. 18. The apparatus of claim 1, wherein displacement of said actuator along said axis is controllable in response to a pneumatic force acting on said actuator. 19. The apparatus of claim 1, wherein displacement of said actuator along said axis is controllable in response to an electromagnetic force acting on said actuator. 20. The apparatus of claim 1, further comprising a ring disposed over said actuator.
