ABSTRACT:
A tweezer mechanism having a pair of electrodes for automatically applying high frequency energy to a hair, upon the hair being gripped precisely in its proper place by the apparatus. The tweezer is comprised of a pair of elongated arms resiliently biased away from each other, the arms having sections adjacent their ends parallel to each other at their closest adjacency, the sections having electrically conductive surfaces for contacting opposite sides of and confining a hair, and an electrical switch operated when the location of the arms is a predetermined distance apart no smaller than the distance between the conductive surfaces being the thickness of a hair. In one embodiment the electrodes are spaced a precise distance from the skin to safeguard against burning and to allow maximum safe energy to be applied, whereby reliable coagulation of the root can occur.
