Abstract
A punch that is particularly useful for removing curled hair follicles from a donor site comprises a generally tubular body disposed about a generally longitudinal axis between distal and proximal ends, and having a distal cutting end region terminating distally in an opposing pair of distally-extending, generally prong-like members having an anterior notch and a posterior notch therebetween. In one variation, the prong-like members each have a curved anterior cutting edge and a curved posterior edge meeting at a cutting tip. In the preferred embodiment, the posterior notch extends proximally further than the anterior notch and has a generally “V”-shaped distal segment which carries cutting edges together with a generally “U”-shaped proximal segment extending proximally from the distal segment.
