Embodiment Construction

[0030]FIGS. 1-7, as to be more particularly described below, relate to several preferred embodiments of devices constructed in accordance with the present invention for applying vibrations to unwanted hair rooted in a body, in order to destroy their roots and remove the hair. Generally speaking, the device grips the hair between a pair of tongs with a predetermined contact force. At the point of contact between the hair and the respective tongs, the hair is subject to mechanical displacements, preferably at a frequency of 100-500 KHz, more preferably 100-350 KHz, and an amplitude of 5-20 microns. The vibrations may be in a direction along the hair shaft, perpendicular to the hair shaft, or a combination of both.

[0031]In cases where only one of the tongs is vibrated, the vibrating tong is referred to as a hammer, and the stationary tong is referred to as an anvil. One part of the hammer is a transducer, e.g., a piezoelectric element, for converting a high-frequency AC voltage to mech...

Abstract

A device for applying vibrations to hair rooted in a body, includes: a pair of tongs having hair-gripping ends capable of being driven into high-frequency vibrations with respect to each other; and a transducer coupled to at least one of the tongs for converting an AC voltage to mechanical vibrations for driving the hair-gripping end into vibrations with respect to generate sufficient heat within the body to facilitate removal of the unwanted hair. The transducer is preferably a piezoelectric element which vibrates the hair at a frequency of 100-500 KHz, preferably 100-350 KHz, and produces a displacement of 5-20 microns.

Description

FIELD AND BACKGROUND OF THE INVENTION[0001]The present invention relates to a device for applying high-frequency vibrations to objects, which device is particularly useful for removing hair.[0002]A hair is composed of a protein named keratin arranged in three layers, termed the outer cuticle, the middle cortex and the central medulla. Hair grows from a follicle, which is a small cup-shaped pit buried under the skin. The walls of the follicle form the outer root sheath of the hair. The base of the hair follicle called the dermal papilla, is fed by the bloodstream which carries nourishment (e.g., nutrients and oxygen) to produce new hair and removes waste materials formed in the process (e.g., CO2). The lower part of the follicle widens out to form a hair bulb containing a germinal matrix, which is the source of hair growth. Hair growth is initiated in the hair bulge, which is a small swell of the hair follicle that forms the attachment site of a small smooth muscle, called the arrect...
