Description
OPERATING HEAD FOR AN AUTOMATIC DEVICE FOR SKIN MICRODERMABRASION
FIELD OF THE INVENTION
The present invention relates to the technical field of automatic devices for skin microdermabrasion used for performing skin aesthetic treatments.
DESCRIPTION OF PRIOR ART
Modern society gives much importance to aesthetical image, and as a consequence people do not want to grow old or at least they want to slow down skin ageing as much as possible, which is the most perceived. Moreover, the need to eliminate or at least to minimize skin imperfections is very felt as well, as for example wrinkles, wrinkledness, scars, skin relaxation, fat, stretch marks, cellulite etc. The body parts more exposed and therefore more visible are obviously face, neck, hands, and in case of women, the decollete; in addition to the very much felt need to improve the aesthetic image of abdomen, legs and arms. Currently, there are provided automatic devices for microdermabrasion with a handgrip, also said "handpiece", whose distal end comprises an operating head comprising a cylinder. The cylinder has a respective longitudinal axis and, distally, a first edge. The piston comprises in turn: a distal support element having a wall substantially perpendicular to the longitudinal axis; and a plurality of distal needles originating from the wall and whose length is greater than the skin thickness. Such piston can be slidingly introduced in said tubular element with said plurality of needles facing towards said first edge. The device comprises also piston actuating means which are configured to actuate it repeatedly and, from a first operating position, in which the plurality of needles is completely arranged inside the tubular element, to a second operating position in which the piston wall is inside the cylinder and the plurality of needles projects only partially from said first edge. When the first edge is in contact to the skin, by actuating the piston the needles penetrate partially the skin perforating it up to the dermis. The microdermabrasion effect is obtained by making the head sliding along the skin to be treated while the piston is actuated. As a consequence, while the head slides on the skin, while the needles penetrate the skin they abrade it causing a plurality of micro-trauma which trigger a reparation mechanism of the skin cells. This causes a greater
production of collagen and elastin, thus increasing the respective concentration thereof in the skin. The person undergoing such technologies can feel pain and be subjected to a temporary aesthetical worsening due to irritation, bruises, etc. Despite the improvements obtainable by means of such a device it lingers the need for a skin treatment with better performance from an aesthetical point of view and/or less temporary worsening.
SUMMARY OF THE INVENTION
Aim of the present invention is to provide a skin treatment with better performance from an aesthetical point of view than the known technique. Moreover, one of the main aims of the present invention is to allow a lower number of treatments to be carried out on the skin, with equal aesthetic effect obtainable. Another aim of the present invention is to obtain a more lasting aesthetic effect than with the known technique.
Said aim is obtained by using an operating head according to claim 1 , which can be used in an automatic device for skin microdermabrasion according to claim 6.
In fact, by means of the operating head and the present device, it is possible to subject the skin also to a radial shock wave. The synergetic effect of this latter one with the microdermabrasion allows to obtain other aesthetic advantages, described in the following. Since the skin has a respective elasticity and stretching capacity the configuration of the piston of head according to the invention is fundamental to propagate an acoustic wave of radial type in the skin. In fact, when the length of the perforating elements is between 1-2 mm, by actuating the piston, the perforating elements penetrate at least partially the skin first, thus perforating it. In the following, the tensioning elements touch the deformed skin tensioning it, thus allowing the perforating elements to penetrate the punctured skin for the whole length thereof and, finally, when the skin is punctured and tensioned it is touched also by the portion of wall allowing the propagation of an acoustic wave of radial type in the skin, due to the impact of such portion on the skin.
When instead, the length of the perforating elements is lower than 0,2 mm, by actuating the piston, the perforating elements touch the skin first and deform it. After that the tensioning elements touch the deformed skin, tensioning it, thus allowing the perforating elements to penetrate the tensioned skin for the whole
length thereof, thus perforating it. Finally, the portion of the wall touches the tensioned and punctured skin thus allowing the propagation of an acoustic wave of radial type in the skin, due to the impact of the wall on the skin.
Such head, when mounted in an automatic device for skin microdermabrasion according to the invention, allows to carry out the skin microdermabrasion, which alone leads to the same above cited effects concerning the automatic devices for skin microdermabrasion of known type. Moreover, the micro-hammering action of the portion of wall on the skin due to repetitive impacts determines the formation of shock waves, specifically acoustic waves of radial type, which lead to additional different effects, such as:
- blood micro-circulation increase in the treated part (neoangiogenesis)
- cellular metabolism stimulation of the skin structures with increase in membrane permeability. Such effect increases the vehiculation of the active principles present in possible cosmetic creams, spread on the skin by the operating head before treatment; and
- mechanical stimulation of fibroblasts with consequent additional increase in production of collagen and elastin.
Moreover, at the same time the mechanical action of the operating head according to the invention on the skin cellular structures determines both cellular membrane stretching and compression of said creams spread on the skin. This is due to the combination of tensioning elements and impact of said portion of wall on the skin. This causes the increase in the transdermal penetration of the active principles present in said creams. It is thus simplified the vehiculation up to dermis of such active principles which will result in very much higher concentrations with respect to the concentrations obtainable by a treatment carried out by means of a device for microdermabrasion having a head of known type, on skin on which said cream was previously spread.

DESCRIPTION OF PREFERRED EMBODIMENTS
With reference to such figures, 10 indicates the operating head for an automatic device 12 for microdermabrasion of skin 9 according to the invention. Such operating head 10 comprises a piston 2-cylinder system, comprising in turn: a tubular element 1 acting as cylinder of said piston-cylinder system and which is provided with a respective longitudinal axis 3, and distally a first edge 8; and a
piston 2 comprising in turn: a distal support element having a wall 4 substantially perpendicular to said longitudinal axis 3; and a plurality of distal perforating elements 5, projecting with respect to said wall 4 to perforate the skin 9, wherein the piston 2 can be slidingly introduced in said tubular element 1 with said plurality of perforating elements 5 faced to said first edge 8. The operating head 10 is characterized in that the piston further comprises a tensioning element 6 for each perforating element 5 provided in said plurality of distal perforating elements 5, and in that each tensioning element 6 originates from said wall 4 and tapers distally while having a respective distal surface 7 from which a respective perforating element 5 projects in order that, when the first edge 8 is in contact to the skin 9 and the piston is repeatedly actuated from a first operating position, in which the plurality of perforating elements 5 is completely arranged inside the tubular element 1 , to a second operating position in which said wall 4 is coplanar to said first edge 8, a combined effect of the perforating elements 5 and tensioning elements 6 is obtained which allows the perforating elements 5 to penetrate the tensioned skin 9 for the whole length thereof, thus perforating it, and in order that the skin 9, tensioned and perforated, is brought in contact to a portion of wall 4, free of the tensioning elements 6 with consequent propagation in the skin 9 of a radial acoustic wave 11 , due to the impact of such portion of wall 4 on the skin 9 (see figure 31).
Preferably, the distal surface 7 is substantially parallel to said wall 4 to increase the tensioning effect on the skin 9. Advantageously the distal surface 7 has an area between 0,05 m2 and 0,01 mm2, preferably between 0,06 mm2 and 0,08 mm2, more preferably about 0,07 mm2. Preferably the distal surface 7 is arranged at a distance from the wall 4 between 0,25 and 0,35 mm, preferably between 0,27 mm and 0,32 mm and advantageously such distance is about 0,3 mm. It is preferable that the perforating element 5 projects centrally from the distal surface 7 of the tensioning element 6 to maximize the tensioning effect of this latter one. The height of each perforating element 5 can be between 0,05 and 2,00 mm.
The density for surface unit of the wall 4 of said perforating elements 5 is advantageously between 7 and 10,5 (preferably between 8 and 9) perforating
elements for cm2 of total surface of the wall 4, since a greater density would hinder the initial penetration of the perforating elements 5 in the skin 9 and a lower density would reduce the tensioning effect on the skin 9 of the tensioning elements 6, with a consequent lower efficacy of penetration of the perforating elements 5 in the skin 9 and of the impact of said portion of wall 4 on the skin.
It is preferable that the distal surface 7 of each tensioning element 6 is substantially parallel to said wall 4 and that it is arranged at a distance between 0,25 and 0,35 mm from the wall 4. In such way, by actuating the piston 2, the tensioning effect on the skin 9 is maximized. According to a preferred aspect, the tensioning element 6 can be a truncated cone since this latter does not have longitudinal comers.
Therefore it is preferred an operating head according to the invention, in which each tensioning element 6 is shaped as a frustum of cone having a major base of diameter between 0,45 and 0,55 mm and a minor base, which defines said distal surface 7, of diameter between 0,25 and 0,35 mm.
According to another embodiment, not shown, the tensioning element 6 can be a cross section of a pyramid with polygonal base, which has preferably respective parallel bases, wherein the major base is fixed to the wall 4 and the minor base defines said distal surface 7. In such a case, the development of such major and minor bases is preferably equal to the one of the major and minor bases of said truncated cone.
According to a preferred embodiment, each perforating element 5 is a cone having a respective height between 0,05 and 2,00 mm and a respective base arranged on the distal surface 7 of the respective tensioning element 6, in which said base has a diameter between 0,08 and 0,12 mm. This is particularly advantageous when the tensioning element 6 is shaped as a frustum of cone. The microdermabrasion treatment with perforating elements 5 of length greater than 0,2 mm implies the need of a highly skilled operator, i.e. a cosmetic doctor. As a consequence, the respective costs are high and therefore not everybody can afford them. Moreover, the person undergoing such technologies can feel pain and be subjected to a temporary aesthetic worsening due to irritation, bruises etc. Therefore it is preferred that each perforating element 5 has a maximum height
equal to or lower than 0,2 mm to perforate only the epidermis. This allows a treatment of the skin 9 which can be carried out also by beauty specialists so that the majority of consumers can afford it. In such a case the device, according to the Italian regulations, falls within the category of devices for tapping electric massaging. Moreover, this makes the treatment less painful and implies less temporary aesthetic worsening. However the perforation of the epidermis only, together with the effect of the acoustic wave 11 on the skin 9 allows to obtain a really better aesthetic effect than the one obtainable with the operating heads of known type. It is particularly preferred an operating head 10 in which the tensioning elements are truncated cones whose distal surface has a diameter about 0,3 mm, is parallel to the wall; and is arranged at about 0,3 mm from this latter one, while the major base of the truncated cone, fixed to the wall, has a diameter about 0,5 mm. In such a head, the perforating elements are cones of length lower than 0,2 mm and base of diameter equal to about 0,1 mm. Moreover, said density can be about 8,8 perforating elements for cm2.
It is obviously preferred an automatic device 12 for microdermabrasion of the skin
9 which comprises an operating head 10 according to the invention, and piston actuation means 2 configured to actuate repeatedly said piston 2 from said first operating position to said second operating position for microdermabrasion of the skin 9 and to propagate an acoustic wave 11 of radial type in the skin 9, in particular when such device 12 comprises a handgrip 13 (also said hand-piece) and the operating head 10 is fixed distally in said handgrip 13.
According to a preferred aspect of the invention such device 12 comprises further: a sleeve 14 comprising distally a second edge 15, the sleeve 14 being fixed to said handgrip 13 and being arranged outside and coaxially to the operating head
10 with the second edge 15 projecting with respect to said first edge 8; and suction means which, when the second edge 15 rests on the skin 9, can be actuated to suck air from the sleeve 14 to lift the skin 9 thus bringing it in contact with said first edge 8 (see figures 29-30). Such device 12, in addition to induce an endodermal massage, allows the sucked plica of the skin 9 to adhere perfectly to the portion of wall 4 free of tensioning elements 6 during the impact. In such way, the mechanical action of the piston 2 on the skin 9 has a maximum stimulating
action of the integrins, which are mechanical trans-membrane receptors, and which are intended to the secretory stimulation of collagen and elastin of fibroblasts. Thus, with such device 12 it is possible to obtain a particularly marked aesthetic effect. Preferably the second edge 15 projects with respect to the first one between 0,3 and 0,6 cm, preferably between 0,35 and 0,50 cm, advantageously 0,4 cm.
From a dimensional point of view, considering a circular shape of the edges, the first edge 8 can have a diameter between 1 ,0 and 2,5 cm, preferably between 1 ,0 and 1 ,5 cm, advantageously between 1 ,1 ad 1 ,2 cm, in particular when the perforating elements 5 have a length equal to or lower than 0,2 mm, and so are particularly suitable for the treatment of skin 9 of hands and face. Correspondingly the second edge 15 can have a diameter between 2,0 and 4,0 cm, preferably between 2,5 and 3 cm, advantageously between 2,5 and 2,8 cm. If the shape of the edges is not circular, the respective perimeter can be equal to the one of the circumferences having said diameters.
It is particularly preferred an automatic device 12 for microdermabrasion of the skin 9 according to the invention which further comprises: a first generator of radiofrequency electric signals; a sleeve 14 realized in an electrically insulating material, fixed to said handgrip 13 and arranged outside and coaxially to the operating head 10; the sleeve 14 comprising distally a second edge 15; and two legs 17, 18 of an electric circuit, wherein each one of the two legs 17, 18 has: a respective first electric terminal 16, 19 electrically connectable to a corresponding electric terminal of said first generator; a respective central portion 22 embedded in said sleeve 14; and at least a respective second electric terminal 20, 21 arranged in the second edge 15 to transmit a radiofrequency current 32 to the skin 9 when the second edge 15 rests on the skin 9 covered by conductive gel (see figure 32).
Thanks to the binary transmission of radiofrequency current 23 in the skin 9, the first structures of skin interested in such transmission are the most superficial ones of the papillary dermis. The radiofrequency current 23 determines an immediate denaturation of the amino acids forming the collagen protein, thus causing its shortening with a consequent lifting effect. For this reason, the bipolar
radiofrequency current 23 gives a lifting effect from the very first treatment and is particularly suitable for treatment of particularly tender areas, as the face. Moreover, this embodiment of the device 12 allows to carry out the treatment with radiofrequency also on the skin 9 of hands. The transmission of said radiofrequency current does not need that the person undergoing the aesthetic treatment holds an electrode. Therefore, such device 12 can be used also on subjects with dental implantations or implants of any type, since, in this case, only the skin 9 is interested by the passage of radiofrequency current. Preferably, along the second edge 15 there are arranged couples of second terminals of the same leg in succession to transmit the radiofrequency current to the skin 9 at two close second terminals 20, 21 of different legs 17, 18 (see figure 21 ).
If the device 12 according to the invention is able to transmit a radiofrequency current 32 to the skin 9, advantageously it can further comprise: a second generator of biphasic voltage, with rectangular wave shape with frequency between 2,0 and 3,0 Hz (preferably between 2,2 and 3, more preferably between 2,4 and 2,6 Hz), in such device, the respective first electric terminal 16, 19 of each of the two legs 17, 18 is electrically connectable to a corresponding electric terminal of said second generator; in order that, when the second edge 15 rests on the skin 9 covered by conductive gel, the skin 9 is electro-stimulated by means of a further current 24 coming from said second generator (see figure 33). In such device 12 there can be used the same terminals used for transmitting the radiofrequency current. In such case, the device 12 is arranged to turn off automatically the first generator when the second generator is turned on, and vice versa. Preferably the wave shape is rectangular with frequency 2,5 Hz. The muscle stress generated by the electro-stimulation provides an immediate tensioning effect (lifting effect), favours the dilatation of pores of the skin 9 thus facilitating further the absorption of active principles and determines an increase in contractile capacity of the skin 9 by giving luminosity and freshness to it. Moreover, both the electro-stimulation and the transmission to the skin 9 of a radiofrequency current 32 provide a synergetic effect with the microdermabrasion and the transmission of the acoustic wave. This allows to obtain a greater aesthetic efficacy of the treatment carried out with the device according to the invention.
It is preferable that, in said automatic device 12 for microdermabrasion of the skin
9, able to transmit to the skin 9 a radiofrequency current and to electro-stimulate the skin 9, the second edge 15 projects with respect to said first edge 8; and that such device 12 comprises also suction means which, when the second edge 15 rests on the skin 9, can be actuated to suck air from the sleeve 14 to lift the skin 9 thus bringing it in contact to said first edge 8.
It is intended that what above stated is only described as a way of not limiting example, and that possible variants of applicative-practical nature are intended to fall within the protection scope of the invention, as claimed in the following.
