Description

Bipolar radiofrequency or high applicator frequency for skin tissue therapies.

Object of the invention

The present invention is referred to as its title indicates a bipolar radiofrequency (RF) or high applicator frequency (HF) for skin tissue therapies.

Background of the invention

The therapies of the skin tissues in which radiation is applied electromagnetic on the area to be treated.

For this, equipment is usually used provided with a high frequency generator to which they are connected some plates that act as active electrode and return electrode and that are positioned more or less static on the patient's body.

The use of these plates does not result especially comfortable for certain treatments due to the Difficulty moving over the treated area.

This section also highlights the existence of utility model 200302835, of the same applicant, referring to a high frequency applicator, in which the active electrode and one or more return electrodes are found associated with a handle-like housing that allows grip and handling of the active electrode and return electrodes associated to it.

The aforementioned applicator greatly simplifies the displacement of the electrodes on the area to be applied with respect to the plates used previously.

In the mentioned utility model the electrode active is associated with a vibrating element, housed in inside the housing and transmitting it to said electrode activate vibrations while using the applicator, getting a better treatment efficiency.

Also in said applicator it was contemplated that the return electrodes will be associated to a plate of support provided with a contact for connection to the generator high frequency, the set consisting of said support plate and the return electrodes associated with the same. In this type of applicator, the use of electrodes with sharp edges or angles causes a concentration of the radio frequency in these areas, which prevents its application uniform over the area to be treated with electrodes with edges 5.

Description of the invention

The bipolar radiofrequency or high applicator frequency object of this invention, being of the type described previously, it has the peculiarity of incorporating some sensitively spherical configuration electrodes to avoid radio frequency concentrations in specific areas and provide a homogeneity of the energy transmitted to patient.

This applicator comprises one or more electrodes assets and one or more return electrodes with the aforementioned spherical configuration, said associated electrodes being to the housing and arranged coplanarly.

By using more than one electrode active or more than one return electrode, this applicator can simultaneously produce two or more electromagnetic fields, having anticipated that, the active electrodes are at a same distance from the common active electrode or the corresponding ones active electrodes

This particularity allows to apply simultaneously two or more fields. electromagnetic over the zone a treat, said electromagnetic fields being equal, due to the equal distance between the active electrode and the return electrode of each of the pairs of electrodes active return.

In this way, an equal treatment is achieved. depth over a wider area, avoiding the use of high powers that could be harmful in the therapy to perform.

Another of the peculiarities of this invention is that both the active electrodes and the electrodes of return have a metal core, preferably steel stainless, with a double outer protection composed of a first ceramic plasma layer and a second protective layer External polyamide, plastic or Teflon. This second layer protective is intended to contact the skin of the patient.

Double electrode protection eliminates the risk of perforation of protection and possible damage to patient.

As in the aforementioned background, it has provided that the return electrodes are mounted on a common support plate provided with a contact for connection with the radio frequency or high frequency generator, being able to be replaced the assembly formed by the return electrodes and the support plate by another similar group in which the return electrodes are more or less distanced from the active electrodes, this distance being fixed at each of the pairs of active-return electrodes.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, with character Illustrative and not limiting, the following has been represented:

- Figure 1 shows a perspective view of the applicator object of the invention provided with two electrodes active and two return electrodes, spherical configuration and equidistant from each other.

- Figure 2 shows a partial view in perspective of the anterior area of the applicator of the previous figure partially sectioned

- Figure 3 shows an elevation view of one any of the electrodes longitudinally sectioned to allow the observation of the metal core and the two protective coatings

Preferred embodiment of the invention.

In the exemplary embodiment shown in the figures, the applicator of the invention comprises a housing (1) and, in its previous part, two active electrodes (2, 2 ') that pass, without contact, through holes defined in a plate (4) carrier of two return electrodes (3, 3 '). Both the active electrodes (2, 2 ') such as return electrodes (3, 3') they have a spherical configuration to achieve a homogeneity in the transmission of energy to the patient.

The pairs of active and return electrodes (2, 3) (2 ', 3') are arranged in parallel and connected a high frequency generator (not shown), keeping each active electrode (2, 2 ') at the same distance from the respective return electrode (3, 3 '), producing two fields same electromagnetic.

The active electrodes (2, 2 ') are found fixed to a vibrating element (5), housed inside the housing (1) and mounted on o-rings (6) that prevent the transmission of vibrations to said housing (1).

The set formed by the plate (4) and the Return electrodes (3, 3 ') is replaceable, and can be replaced by another analog set, in which the electrodes of return are distanced to a greater or lesser extent, but that keep on. mounting position, at the same distance with respect to the corresponding active electrodes (2, 2 ').

Therefore, changing the carrier plate (4) of the electrodes (3, 3 ') can vary the distance between the return electrodes and active electrodes and consequently the depth of the electromagnetic field generated by the applicator

The plate (4) carrying the electrodes return features a rear pin (7), for coupling detachable with respect to the housing (1).

This applicator also has some indicator lights (8) indicators of the operating status of the applicator

As seen in the section of any one of the electrodes shown in figure 3, said electrodes they have a metallic core (9) of stainless steel and a double outer protection composed of an inner layer (91) of plasma ceramic and an outer layer (92) of Teflon.

Once the nature of The invention, as well as a preferred embodiment, is for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
