FIELD OF THE INVENTION
The present invention relates to the field of permanent makeup. More particularly, the present invention relates to a device and method for inserting pigment in the skin giving an appearance of hair follicles on the skin.
BACKGROUND OF THE INVENTION
Many people suffer from partial hair loss on the head scalp. Several areas in various shapes on the scalp do not enable the growth of hair on them, causing a lack of comfort in some people. Attempts have been made to hide or disguise these areas by coloring them or by sticking artificial hair on to them.
US 2007/0157400 relates to a method for cosmetically coloring scalp balding areas involving drawing hair into preferred hairdressing form to exposed balding areas, and bringing cosmetic core end of elongated pencils against the balding areas to color the exposed sections.
US 2010/0292723 relates to a disk needle roller for forming micro-holes in a surface of skin by using micro-needles to stimulate and assist regeneration of the skin.
US 2007/0073217 relates to an apparatus for delivering a bioactive material to a subterranean layer of a skin. Architecture is provided that includes a head including one or more needles that are operable to penetrate the stratum corneum of the skin.
US 2009/0118698 relates to a device and a process for introducing an active ingredient into the skin. The device comprises a roller that is mounted to rotate around the longitudinal axis thereof and on whose outside peripheral surface a number of needles project radially outward. After the active ingredient has been applied on the skin, the roller rolls over the skin. In this case, the needles penetrate the skin and open up fine channels there, through which the active ingredient penetrates through the epidermis up to the dermis.
None of the prior art devices and methods provides an efficient manner of giving a natural appearance of hairs or hair follicles within bald areas of the skin.
It is therefore an object of the present invention to provide a method and means for giving bald areas on the scalp a natural appearance of hairs and hair follicles.

Herein, the distal direction in relation to the roller device 1 and in relation to each of its components (when placed in a correct orientation as shown in FIG. 1c) is the direction pointed by the arrow 5 in FIG. 1c away from the user. The proximal direction is the opposite direction to which the arrow is pointing to, in relation to the roller device 1 and in relation to its components.
The roller head unit 20 is used as a base for the rotating structure 2 as shown in FIGS. 1a, 1b, 1c, 1d, 3a and 3b. The rotating structure 2 connects to the roller head unit 20 between the distal arms 21a and 21b. The roller head unit 20 further comprises a proximal portion 23 that connects to the roller tube 50, as will be explained hereinafter.
According to one aspect of the present invention, the length of the roller head unit 20 is usually 30-50 mm and preferably 43.55 mm, and its width (the distance between the edges of distal arms 21a and 21b) is usually 30-40 mm and preferably 35.6 mm. The height of the roller head unit 20 is usually 12-24 mm and preferably 17.55 mm (FIG. 3b). Each one of the arms 21a and 21b comprise a pin 22 fit to hold the female pin 30 and male pin 35 after being placed into depressions 25 comprised in their base portions. The depressions 25 can be shown in FIGS. 1c, 4c, 4g 13a and 13b. The pins 22 are fit to hold rotating structure 2 by being placed into the depressions 25 thus securing rotating structure 2 to the roller head unit 20.
The roller female element 30 (as shown in FIGS. 4a, 4b, 4c and 4d), is usually 18-28 mm and preferably 23.8 mm long. The diameter of the shaft 33 is usually 3-5 mm and preferably 3.9 mm. The length of the hollow portion 31 (within the shaft 33) is usually 7-13 mm and preferably 9.9 mm. The diameter of the roller female element base portion is usually 8-14 mm and preferably 11 mm. The base portion 34 comprises a depression 25 such that pin 22 is fit to be placed in the depression 25 and thus holds and assists securing rotating structure 2 to the roller head structure 20, as explained hereinabove.
One or more roller needle discs 45 and/or roller discs 40 are threaded through and mounted on the shaft 33 of roller female element 30 as shown in FIGS. 13a and 13b. When the roller male element 35 is connected and secured to the roller female element 30, pressure is applied on the roller discs 40 and roller needle discs 45 securing them to one another. The roller discs are substantially used as spacers. The distance between needle discs can be enlarged when placing more roller discs 40 between two adjacent roller needle discs 45. The outcome of the distances between the appearances of hair follicle “dots” is accordingly. In a preferred embodiment, one roller disc 40 is placed adjacent to a roller needle disc 45, as shown in FIGS. 13a and 13b. Then a roller disc 40 is placed, then a roller needle disc 45, etc., until the whole length of the shaft 33 is filled with a plurality of roller needle discs 45 with one roller disc 40 placed in-between two adjacent roller needle discs 45.
FIGS. 5a, 5b, 5c and 5d show different angles of the roller disc 40. The diameter of the roller disc 40 is usually 8-14 mm and preferably 11 mm. The diameter of the center aperture 41 is usually 3-5 mm and preferably 4 mm. The thickness of the roller disc 40 is usually 0.1-1.2 mm and preferably 0.9 mm.
FIGS. 6a, 6b and 6c show different angles of the roller needle disc 45. A plurality of needles radially project from the outside circumference of the needle disc. The diameter of the roller needle disc 45 (not including the needles 46) is usually 8-14 mm and preferably 11.2 mm. the lengths of the needles 46 is usually 1.4-1.7 mm and preferably 1.6 mm, what usually prevents the needles of penetrating into more than 1.5 mm of the dermis. The distance between the peeks of two adjacent needles is usually 1-2 mm and preferably 1.37 mm. The thickness of the roller needle disc 45 is usually 0.1-0.3 mm and preferably 0.2 mm.
The roller male element 35 (as shown in FIGS. 4e, 4f, 4g and 4h), is usually 5-15 mm and preferably 10.1 mm long. The diameter of the mail base portion 36 is usually 8-14 mm and preferably 11 mm. The diameter of the imaginary circle 37, that encircles the elements 38 attached to the shaft 39 of the roller male, is usually 1.5-3.5 mm and preferably 2.3 mm. The elements 38 assist in securing the roller male 35 to the roller female 30 in a tight efficient manner when the male element 35 is placed within the female element 30. The discs 40 and needle discs 45 are pressed together tightly and secured together when the male element 35 is placed within the female element 30.
The base portion 36 comprises a depression 25 such that pin 22 is fit to be placed in the depression 25 and thus holds and assist securing rotating structure 2 to the roller head structure 20, as explained hereinabove.
In another embodiment, the male 35 and female 30 comprise pins instead of the depressions. Accordingly arms 21a and 21b comprise depressions instead of the pins 22, such that the pins of the male 35 and female 30 are placed in arms 21a and 21b depressions.
According to another embodiment of the present invention, the rotating structure is comprised of a cylindrical element, the length of which is adapted to fit between the arms 21a and 21b. The cylindrical element diameter is preferably similar to that of the roller discs 40 as explained hereinabove. A plurality of small needles, usually 1-3 mm and preferably of the size of 1.5 mm, are attached to the surface of the cylindrical element. The needles are attached by one of the following methods: Sticking, brazing, screwing, adhesion, etc.
The attachment of the rotating structure to the roller head can be by pins and depressions as explained hereinabove (in relation to the rotating structure comprising either pins or depressions) or by placing a bar through the rotating structure wherein the bar is then connected between arms 21a and 21b. Optionally the bar is placed through a plurality of discs and/or needle discs.
The roller tube 50 (shown in FIGS. 7a, 7b, 7c and 7d) is a tubular element that comprises an interior, the shape of which is in accordance with shape of the roller head proximal portion 23, and fit to secure portion 23 therein and prevent circular motion of portion 23. Accordingly it prevents circular motion of the entire roller head unit 20. In a preferred embodiment, the tube interior is rectangular shaped. The width of the rectangular is usually 3-5 mm and preferably 3.80 mm.
The distal portion 51 of the roller tube 50 is preferably thicker than the proximal body 52. The diameter/height of the distal portion is usually 6-12 mm and preferably 8.8 mm wherein the diameter/height of the proximal body 52 is usually 5-10 mm and preferably 7.6 mm. The length of the roller tube 50 is usually 12-22 mm and preferably 17.4 mm.
The roller spring 55 (FIGS. 8a, 8b and 8c) length is usually 8-15 mm and preferably 11.5 mm. The diameter of the spring 55 is usually 4-7 mm and preferably 5.4 mm.
Any suitable elastic element can be used and not necessarily spring 55. According to an embodiment of the present invention, the elastic element is a rubber membrane used instead of spring 55. The rubber membrane comprises elastic properties which gives a similar spring effect to that of spring 55. The dimensions of the rubber membrane are adapted in order to be placed in tube 50 and are preferably similar to the sizes of spring 55.
The roller head pin 60 (FIGS. 9a, 9b and 9c) is usually 22-30 mm and preferably 27 mm long. The roller head pin 60 comprises a distal portion 61. The roller head pin 60 further comprises a wide middle portion 62 and a proximal body portion 63, wherein said proximal body portion 63 is usually 20-25 mm and preferably 22.5 mm long. The proximal body portion 63 comprises a dome shaped portion 64. The diameter of the proximal body portion 63 is usually 1.5-4 mm and preferably 2.2 mm, and the diameter of the wide middle portion 62 is usually 3-8 mm and preferably 5.45 mm. The thickness of the wide middle portion 62 is usually 0.5-2 mm and preferably 1 mm.
The roller head cap 65 (FIGS. 10a, 10b and 10c) comprises three main disc shaped portions with a common central lumen 69. The roller head cap 65 comprises a distal disc shaped portion 66, usually with a diameter of 4-8 mm and preferably with a 5.95 mm diameter and usually with a thickness of 2-4 mm and preferably a thickness of 2.5 mm. The roller head cap 65 comprises a central disc shaped portion 67 usually with a diameter of 5-10 mm and preferably with a 7.5 mm diameter and usually with a thickness of 0.5-2 mm and preferably a thickness of 1 mm. The roller head cap 65 comprises a proximal disc shaped portion 68 usually with a diameter of 3-8 mm and preferably with a 5 mm diameter and usually with a thickness of 1-3 mm and preferably a 2 mm thickness. The diameter of the common central lumen 69 is usually 2-4 mm and preferably 2.6 mm.
Putting together the roller device 1 can be seen in FIGS. 1c and 1d. The roller head proximal portion 23 is introduced into the roller tube 50 from its distal end and placed and secured therein. The spring 55 is also introduced in the tubular member 50 from its proximal end followed by the roller head pin 60. The roller head pin 60 is placed within the central lumen 69 of cap 65. This is achieved by pushing the cap 65 distally such that the common central lumen 69 it passes along the proximal body portion 63 of the roller head pin 60 until it closes and seals the proximal end of roller tube 50, such that inner lumen of the roller tube 50 encases within its inner lumen, the roller head proximal portion 23, the spring 55, the roller head pin distal portion 61, the wide middle portion 62, the distal portion of the proximal body portion 63 and the distal disc shaped portion 66 of cap 65. The proximal portion of the proximal body portion 63 extends out of the roller cap 65 seal in a proximal direction. This is shown in FIG. 1d. 
The spring 55 is placed in-between the wide middle portion 62 on its proximal end and an edge wall portion, within the inner lumen of the roller tube, in its distal end. When the pin 60 is pushed distally it causes the contraction of the spring. Accordingly, the spring applies an outward proximal directed force pushing the roller head pin 60 back proximally.
According to another aspect of the invention (a preferred aspect), the roller device comprises features and sizes that enable a very efficient appliance of pigment to the skin in a manner which provides a very good appearance of hair or hair follicles on the skin. The roller device comprises less needle discs and less needles on each disc and a unique applied needle structure. The task and essence of the elements according to this preferred aspect of the invention are similar to the task and essence of the elements described hereinabove regarding the previous aspect of the invention, however their unique configuration enables a very efficient function of the device. The following description and figures describe this preferred aspect of the invention.
FIGS. 14a, 14b and 14c illustrate an embodiment of a roller device 100 with 4 identical needle discs and 4 roller discs on the rotating structure 102. The length of the roller head unit 120 is usually 30-40 mm and preferably 38.6 mm, and its width (the distance between the edges of distal arms 121a and 121b) is usually 12-18 mm and preferably 15 mm (FIG. 15a). The height of the roller head unit 120 is usually 10-15 mm and preferably 12.4 mm (FIG. 15b).
The roller female element 130 (as shown in FIGS. 16a, 16b, 16c and 16d), is usually 10-15 mm and preferably 12.47 mm long. The length of the hollow portion 131 (within the shaft 133) is usually 7-13 mm and preferably 9.5 mm. The diameter of the roller female element base portion 134 is usually 8-14 mm and preferably 11 mm. The roller female element 130 comprises a straight elongated protruding portion 132 along the shaft 133, that assists in fixating the roller discs and needle discs to the female element 130, such that they will not move out of place.
FIGS. 17a-17b illustrate the roller disc 140 which comprises an aperture portion 142 extending out of the center aperture 141, adapted to fit on the straight elongated protruding portion 132. This provides the roller disc 140 with stability such that it will not move out of place. The thickness of the roller disc is usually 1.5-3 mm and preferably 2 mm.
FIG. 18a shows the identical roller needle discs 145. The diameter of the roller needle disc 145 (not including the needles 146) is usually 8-14 mm and preferably 11.2 mm. the lengths of the needles 46 is usually 1.2-1.7 mm and preferably 1.4 mm. Preferably, the distance between each two adjacent needles is the same. The distance between the peeks of two adjacent needles is usually 1-4 mm and preferably 3.12 mm. The thickness of the roller needle disc 145 is usually 0.1-0.4 mm and preferably 0.25 mm. The bottom portion of each needle attached to the needle disc edge is usually 0.15-0.4 mm and preferably 0.23 mm (wherein the needle itself from the peek has about a 9° angle). The number of needles on each disk is usually 12-16 and preferably 14. This number of needles on each disc with the disc diameter size enables a more efficient and natural appearance of hairs and hair follicles when applied on the scalp.
The needle disc 145 comprises one or more aperture portions extending out of the center aperture and preferably two aperture portions 147, as shown in FIG. 18a, each aperture portion is adapted to fit on the straight elongated protruding portion 132. This provides the roller needle disc 145 with stability such that it will not move out of place. The two aperture portions 147 form a two ear like structure (also used herein interchangeably with aperture portion) both tending to be on one half of the needle disc 145 thus defining a left and right aperture (ear). The roller device 100 is constructed by mounting the needle discs 145 on the female pin 130 such that:

    
    
        a) the first needle disc right ear is mounted on the elongated protruding portion 132,
        b) then the first roller disc 140 is mounted,
        c) then the second needle disc left ear is mounted on the elongated protruding portion 132,
        d) then the second roller disc 140 is mounted,
        e) then the third needle disc right ear is mounted on the elongated protruding portion 132,
    
    


and so on and so forth such that every two adjacent needle discs 145 (having a roller disk 140 therebetween) are each mounted on the elongated protruding portion 132 alternately at opposite ears (one at a right ear one at a left ear). The relation between said right and left apertures being mounted result in that the needles angular rotational positioning is such as follows: The plurality of needle discs that are positioned along the female element 130 are disposed relatively to one another such that needles which are radially projecting from each disc of a pair of non-adjacent discs could be connected by an imaginary line drawn parallel to the female element 130 and needles which are radially projecting from each disc of a pair of adjacent discs could not be connected by an imaginary line drawn parallel to the female element 130 as shown in FIGS. 19c-19e. The pair of non-adjacent needle discs mentioned hereinabove refers to pairs with only one needle disc in-between them, i.e. wherein said non-adjacent discs have a single needle disc placed therebetween.
According to an embodiment of the present invention, the number of needle discs in the roller device is even such that the discs can be assigned with the numbers 1, 2, . . . 2n−1, 2n. Needles radially projecting from the even needle discs (2, . . . , 2n) could be connected by k imaginary lines drawn parallel to the female element 130, wherein k is the number of needles in each needle disc. Needles radially projecting from the odd needle discs (1, . . . , 2n−1) could be connected by k imaginary line drawn parallel to the female element 130, wherein k is the number of needles in each needle disc. The set of imaginary lines of the even discs and the set of imaginary lines of the odd discs do not coincide. Each imaginary line of the even discs does not coincide with any of the imaginary line of the odd discs.
According to an embodiment of the present invention, the number of needle discs in the roller device is odd such that the discs can be assigned with the numbers 1, 2, . . . 2n, 2n+1. Needles radially projecting from the even needle discs (2, . . . , 2n) could be connected by k imaginary lines drawn parallel to the female element 130, wherein k is the number of needles in each needle disc. Needles radially projecting from the odd needle discs (1, . . . , 2n−1) could be connected by k imaginary line drawn parallel to the female element 130, wherein k is the number of needles in each needle disc. The set of imaginary lines of the even discs and the set of imaginary lines of the odd discs do not coincide. Each imaginary line of the even discs does not coincide with any of the imaginary line of the odd discs.
In this manner the roller device is very effective in giving a natural look of hairs or hair follicles on the skin. The alternately left-right ear positioning is constructed such that in a side view, each needle of a needle disc is substantially placed angularly in-between two needles of its adjacent needle disc (preferably, exactly in the middle). This can give a natural look appearance of hairs or hair follicles on the skin. An example of such an efficient appearance structure can be seen in FIG. 19b. If all the needles would be parallel to their adjacent needle disc needles they would form straight vertical and horizontal dotted line arrays giving a more fake appearance (FIG. 19a).

According to this preferred aspect of the invention, the male pin, the roller tube, the head cap and the spring comprise the same sizes as described hereinabove in relation to the previous aspect of the invention. Also, other portions of the elements that were not explained herein in regards to the preferred aspect of the invention, usually have the same size as the corresponding portions explained in regards to the first aspect of the invention.
The roller device 1 (and 100) is adapted to connect to a vibrating pigmentation treatment device 10 such as the vibrating micro pigmentation treatment device—ORON 56 model of NPM Ltd., as shown in FIG. 2. The ORON 56 (also adapted to work with a single needle) comprises a base unit 11, an operation handle 12, a foot pedal and a power unit—electric plug. The base unit 11 comprises a control unit and appropriate circuitry for controlling the vibration effect on the operation handle connected thereto. Three connectors are connected to the base unit. A first connector connects the base unit 11 to the power unit electric plug adapted to connect to a wall socket. The second connector connects the base unit 11 to the operation handle 12 and a third connector connects the base unit 11 to the foot pedal.
The base unit 11 comprises a POWER on/off button and a PIECE button that enables function and operation of the operation handle 12 by pressing the foot pedal. The base unit 11 further comprises a LIGHT button that turns on (and off) two LEDs located on the upper portion of the operation handle. The base unit 11 further comprises a “+” button that increases the RPM of the motor comprised in the operation handle 12 thus causing a faster vibration of the operation handle 12 and a “−” button that decreases the RPM of the motor comprised in the operation handle 12 thus causing a slower vibration of the operation handle.
As said, the operating handle 12 comprises a motor and also an eccentric system unit fit on the motor that converts the rotational movement of the motor to a distal linear movement of a push pin connected thereto. The push pin is within the cylindrical (pen) shaped operation handle.
The roller device 1 is adapted to connect to a vibrating pigmentation treatment device 10 such as the ORON 56 model of NPM Ltd., as shown in FIG. 2. The roller device is connected to the, vibrating pigmentation treatment device 10 by its push pin being connected to the roller head pin 60 of the roller device.
The dome shaped portion 64 of the roller head pin 60 is pushed into a fitting socket on the distal part of the push pin (of the eccentric system unit). The push pin connected to the eccentric system unit applies a linear distal pushing force pushing the head pin 60 distally moving the whole device distally. The spring 55 within the roller tube pushes the head pin 60 back proximally. Thus, a vibrating motion is formed wherein periodically, the head pin 60 is pushed distally by the eccentric system unit push pin and pushed back in a proximal direction by the spring 55.
Thus, the whole roller head unit 20 is fluctuated causing a vibration on the rotating structure 2. This vibrating motion enables the needles 46, which have been dipped in the pigment, to penetrate the skin thus inserting pigment into the second layer of the skin (the dermis). Doing so, it gives an appearance of hairs or hair follicles on the skin. The vibration effect assists in pushing the needles into the hard skin.
As said, the “+” and “−” buttons of the vibrating pigmentation treatment device 10 increase/decrease the RPM of the motor. When increased the frequency of the fluctuations of the push pin (connected to head pin 60) is increased accordingly giving a faster vibration effect. When decreased the frequency of the fluctuations of the head pin 60 is decreased accordingly giving a slower vibration effect.
An additional element used in connection with the roller device 1 (and 100) is the roller paint tray 75 (shown in FIGS. 11a, 11b and 11c). The rotating structure 2 is dipped in pigment within the tray before being applied on the skin. The length of the roller paint tray 75 is usually 50-70 mm and preferably 61.5 mm. The width of the roller paint tray 75 is usually 35-55 mm and preferably 44.45 mm. The height of the roller paint tray 75 is usually 10-20 mm and preferably 14.9 mm.
An additional element used in connection with the roller device 1 is the roller cover 70 (shown in FIGS. 12a, 12b, 12c and 12d). The roller cover 70 is used for covering and protecting the rotating structure 2, especially the needles during mobility and when it is packed and cased. The length of the roller cover 70 is usually 30-45 mm and preferably 38.65 mm. The height of the roller cover 70 is usually 16-26 mm and preferably 22.55 mm. The radius of the roller cover 70 circular portion 71 is usually 5-15 mm and preferably 9.5 mm.
According to a preferred embodiment the materials comprising the following elements are as follows:
The roller head 20, the pins 30, 35, 60, tube 50 and cap 65 are preferably comprised of plastic or polycarbonate. The roller discs 40 and needle discs 45 are preferably comprised of stainless steel. The spring 55 is preferably comprised of steal—SAE1090 zinc plated. The elements can also be comprised of other appropriate similar materials as known in the art.
The present invention further relates to a kit comprising the roller device 1 (or 100) as described hereinabove and the tray 75 as described hereinabove and the roller cover 70 as described hereinabove.
The present invention further relates to a method for providing pigment in the skin giving an appearance of hair follicles on the skin. Providing a plurality of needles radially projected from the surface of a roller, the method comprises:
