摘要:
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 and having a distal cutting end region terminating distally in a plurality of distally-extending circumferentially disposed, generally prong-like members carrying distally diverging cutting edges and separated by follicle-accommodating slits. In practice, the punch is oriented during the extraction process at the donor site so that the curled hair root passes into, and is spared from the advancing cutting edge by, a slit as the punch is inserted into and penetrates the tissue. The punch may then rotated slightly so that the cutting edges cut most of the tissue surrounding the follicle without making damaging contact with the follicle. It may be noted that a rotary motion may not be necessary and, if rotation is desired, it may be in one direction or be in the form of an oscillatory rotary movement, depending on characteristics of the donor site and targeted follicle.
