Abstract

A skin rejuvenation resurfacing apparatus comprising an oscillating, reciprocating high speed, non-thermal, needle-based device for inducing mechanical trauma to an area of the skin to be treated.

Claims

1. An apparatus for use in a skin rejuvenation resurfacing procedure comprising:

a non-thermal needle base device configured for inducing a mechanical trauma transdermally into the epidermis, dermis and subcutaneous fat;

means for oscillating and reciprocating at a high speed an elongated needle portion of said needle-based device and means for operating said needle based device at about 40 cycles per second to 100 cycles per second to induce a purposeful full skin thickness injury and inflammatory response that leads to collagen, elastic and ground substances to resurface a patient'"'"'s skin;

the needle-based device including needle depth adjustment means for obtaining a desired transdermal penetration needle tip depth sufficient to penetrate through said epidermis, dermis and into said subcutaneous fat of needle tips of a plurality of needles for the appropriate treatment of the area of the skin being treated; and

the needle-based device further comprising;

a hand-held portion comprising means for oscillating and reciprocating an elongated needle portion,

the elongated needle portion being connected at one end to said hand-held portion and in mechanical communication with said means for oscillating and reciprocating said needle portion,

the elongated needle portion having at its opposite end, the plurality of needles configured in a desired array.

2. The apparatus according to claim 1, wherein the needle-based device is a hand-held, mechanical device and is controllable by hands-free means.

3. The apparatus according to claim 2, wherein the hands-free means for controlling the needle-based device is a foot control switch between a power controller source and the hand-held needle-based device.

4. The apparatus according to claim 1, wherein the plurality of needles are arranged in an array comprising between eight to sixteen needles.

5. The apparatus according to claim 1, wherein the needle-based device further comprises:

a needle sheath generally covering said elongate needle portion and connected to the hand-hand portion and ending near the plurality of needles, said needle sheath further serving as means for preventing a side to side movement of the elongate needle portion; and

a needle tip protector attached over the plurality of needles, said needle tip protector being slidably operable over the plurality of needles for serving as the needle depth adjustment means for obtaining the desired depth of needle penetration of said needle tips to the skin area being treated.

6. The apparatus according to claim 5, wherein the plurality of needles are arranged in an array comprising between eight to sixteen needles.

7. The apparatus according to claim 6, comprising twelve needles.
