    DESCRIPTION
    Handle and device for performing invasive electrotherapy treatments comprising said handpiece
    The present invention refers to the field of electromedicine devices. More particularly, the present invention refers to a device for performing invasive electrotherapy treatments, such as the so-called guided endogenous microregeneration, as well as to a handle for said type of device.
    Invasive electrotherapy by means of galvanic current or direct current is an invasive physiotherapy technique developed by the inventor as a result of his research in the field of tendon regeneration and pathophysiology of soft tissues, having scientifically proven that this technique has a great regenerative power in tendinopathies and muscle injuries, as in other soft tissue disorders. Its main application takes place in the tendinopathies sector, although it has also been proven applicable to a significant number of lesions of the neuromusculoskeletal system. Studies have determined that its effectiveness is high (around 80%) with respect to conventional physiotherapy treatments with the same or similar objective (ultrasound, laser, Cyriax technique, diacutaneous fibrolysis, shock waves, etc.) or medical (drugs, infiltrations or surgery).
    In invasive electrotherapy treatments, a metal needle is inserted percutaneously until the altered and / or degenerated tissue to be treated is reached. The needle is connected to a galvanic current emitting device. Once the needle is inserted, galvanic current is applied through the needle. The needle acts as a negative electrode (cathode) of the applied direct electric current, although it is possible to make the needle act as a positive electrode. Galvanic electric current and the mechanical stimulation of the needle itself constitute physical agents characteristic of the therapeutic sector of physiotherapy. The galvanic current is capable of launching new processes of proliferation of collagen tissue that is unstructured. In particular, when the current comes into contact with degenerated fibrotic tissue, it is destroyed by an electrolytic process. In particular, the direct current causes sodium chloride (NaCl) and water (H2O) to break down into its constituent chemical elements, which regroup between them to form completely new substances. This process is called electrolysis. The formation of new substances alters the pH. This electrochemical reaction is an effective non-thermal electrolytic ablation instrument when performed in the region of degenerated tissue of collagen and myxoid substance. The body's inflammatory response to the new situation, which will not be detailed here, produces the synthesis of type III collagen to type I collagen. Degenerated tissue is metabolized by the body itself by phagocytosis.
    In short, a device for performing invasive electrotherapy treatments comprises a galvanic current generator and two electrodes, one of the electrodes comprising a handle for receiving a disposable needle. The handle comprises a receiving port or needle adapter with means for holding and releasing the needle and means for connecting the needle to the galvanic current generator. The handle acts as a connector of the disposable needle to the electrical circuit and as a handle that facilitates the physiotherapist to handle it and its insertion into the tissue to be treated through the skin. The ports or adapter for needles of the handles of known type comprise a metal mechanism that protrudes externally from the body of the handle. It usually has the ability to turn to secure / release the needle

    to / from the port.
    Spanish Patent Documents ES245688A1, PCT Patent WO2014207283 and Utility Model ES1085804U, of the present inventor, describe devices for performing invasive electrotherapy treatments as described above.
    The applicant, however, has determined that the use of galvanic currents can cause corrosion processes at the interface between the adapter and the needle which in turn release ions that, in the context of the conditions generated in the tissue to be treated, may result dangerous to the patient's health, especially in the case that the conditions of maintenance and replacement of equipment are not optimal.
    In particular, Jing-Jin Lee and others in "Evaluation of the effect of galvanic corrosion between nickel chromium metal and titanium on ion release and cell toxicity" (J Adv Prosthodont. 2015 Apr; 7 (2): 172-177) determined the existence of conditions in which a corrosion in which a galvanic current mediates releases ions with toxic effects to the cells in a contact interface.
    The possibility of introducing metal ions associated with needle corrosion processes has been described, and may lead to chronified processes (Zhou and others “Conference Summary and Recent Advances: the 8th Conference on Metal Toxicity and Carcinogenesis” Biological Trace Element Research July 2015 , Volume 166, Issue 1, pp 1-6).
    On the other hand, heavy metal ions show carcinogenesis at all stages of cancer development (Leonard SS, Bower JJ, Shi X “Metal-induced toxicity, carcinogenesis, mechanisms and cellular responses” Mol Cell Biochem. 2004 Jan; 255 ( 1-2): 3-10).
    In the case of currently existing invasive electrotherapy handles, the adapters are made of a metallic material that protrudes from a housing. This means that not only the electrical contact zone, but also the attachment areas of the adapter or needle holder that can come into contact with the needle are metallic, which favors corrosion by being able to present the different conductive parts in different electrical potential contact points and / or different ion concentrations. Additionally, the external arrangement of said adapters not only increases the risk of corrosion and oxidation, but also the accumulation of ctenophores bacteria.
    All this favors the transfer of ionized heavy metals by electrophoresis effect, which in turn implies a greater risk of cytotoxic effects and carcinogenesis by transfer of heavy metals, according to effects already studied and discussed above.
    It is an object of the present invention to disclose a handle for the application of invasive treatments by means of currents, and devices comprising said handle, which achieve a decrease in the risk of transfer of ionized heavy metals to the patient, further simplifying the maintenance conditions and Useful life of these equipment.
    To solve the above problem, the present invention discloses a new handle and a new device for applying invasive treatments by means of currents comprising said handle. He

    Handle features a housing and an adapter to receive a disposable needle. The handle has means for holding and releasing the needle in the adapter and the adapter has an electrical connection for connecting the needle to the current generator. To achieve the aforementioned objective, the adapter is located inside the housing, the housing having a hole for the entry of disposable needles to the adapter.
    In this way, the adapter is protected from receiving ionic or ionizing substances as a result of contact with the operator's hands or gloves and the area of the electrical contact is also protected from moisture and external elements. As a consequence, the galvanic corrosion processes (that is, caused by the current) in the electrical interface are significantly reduced and, with this, the risk of transfer of heavy metal ions into the patient is also reduced.
    Preferably, all parts of the handle capable of coming into contact with the needle are made of non-metallic materials, with the exception of the electrical connection between the galvanic circuit and the needle.
    Preferably, the electrical connection of the adapter is made of a metal with anticorrosive treatment.
    Preferably, the handle has a sleeve interposed between the hole in the housing and the adapter. The purpose of this piece is to provide a tight passage for the needle that prevents the passage from outside of moisture and particles that can facilitate the creation of ions.
    Preferably, the handle has preferably elastic means for holding the activation needle by inserting the needle into the adapter. The handle will also have means for deactivating the clamping means operable through a button located on the handle housing. These means allow the needle to be released by activating a button, and therefore without the need to manipulate the needle after the treatment, which increases the safety of the device against the transmission of pathogens acquired by the needle inside the patient's body. .
    The handle can be designed in such a way that said release means allow the needle to be discarded by gravity.
    The device object of the present invention may comprise the aforementioned handle, a generator of galvanic currents, a positive electrode and a negative electrode, in which the handle can correspond to the positive or negative electrode. Preferably, the handle corresponds to the negative electrode of the device. The device can be sold with a disposable needle kit, or they can be sold separately. The disposable needle will preferably be of the type commonly used in acupuncture.
    For better understanding, some drawings of an embodiment of the handle and the device object of the present invention are attached by way of explanatory but not limitative example.
    Figure 1 shows a perspective view of an embodiment of the device for applying invasive treatments by currents according to the present invention.

    Figure 2 shows an elevation view of an embodiment of a handle according to the present invention.
    Figure 3 corresponds to Figure 2, in which the housing of the handle has been opened in order to be able to observe the interior elements thereof.
    An embodiment example of the invention has been shown in Figures 1 to 3, in the form of a device for applying invasive treatments by means of streams provided with an example of embodiment of a needle holder according to the present invention.
    The device of the example comprises a generator of galvanic currents -2- connected by respective electric cables -21-, -32- to two electrodes. One of the electrodes, in this case the positive electrode -3- has the shape of a bracelet that can be placed around the wrist or ankle of a patient, in contact with their skin. Other shapes of the electrode are also possible, such as a conductive plate. The other electrode, in this case the negative electrode is intended to be introduced through the skin into the tissue to be treated, or close to it. For this, the electrode is constituted as a manipule -1- that has the double function of acting as a needle holder for a disposable needle -4-, as well as facilitating the manipulation of the same by the physiotherapist. The needle -4- can be a common acupuncture needle, in anticorrosive metallic material and suitable for percutaneous use. The handle -1- also comprises a housing -11- made, for example, of plastic material, two current control buttons -13-, -13'- and a button -12- which is intended to activate the release mechanism of the needle inserted into the handle. By arranging the release mechanism in this way, the physiotherapist can arrange the handle with the needle facing down, placing it above the appropriate waste receiver or collector and pressing the button -12-, which makes the needle -4- fall by gravity, leaving the handle without the need for the physiotherapist to touch the needle. In this way, the risk of infection of the physiotherapist by contact or accidental needle prick is minimized.
    The galvanic current generator should preferably allow the generation of direct current either continuously or in the form of trains, and preferably also offers the possibility of modifying the current intensity.
    Typically, the needle holder or adapter element -16- is located inside the housing -11- of the handle, such that the needle -4- must be inserted through a hole -14- located in the housing -eleven-. In this way, the adapter -16- is protected from corrosion. For greater protection of the interface, a sleeve -15- whose function is to define a narrow passage for the needle -4- that prevents or hinders the passage of moisture and particles (such as charged ions) to the area has been located of the adapter, where they could favor the formation of heavy metal ions as a result of galvanic corrosion processes at the contact interface between the adapter -16- and the needle -4-. In the embodiment shown, the sleeve -15- is an independent part, but could be an integral part of the housing, if desired.
    The needle clamping means -4- in the adapter -16- of the example are activated when the needle is inserted, by pushing. This facilitates placement. There are numerous technical solutions to achieve the activation of the support by pushing, so the mechanism will not be described in detail. The fastening system, in this case, includes elastic elements, in particular springs -18- that can be used both to perform the
    clamping force, as to facilitate the release of the clamping mechanism when the button -12- is pressed.
    The adapter also includes the corresponding electrical equipment -19- and an electrical contact area -17- that contacts the needle -4-, once inserted, with the galvanic circuit.
    5
    In the example shown, all the elements capable of coming into contact with the needle, except for the electrical contact -17- are made of non-metallic materials, such as plastics. This can also be extended to elements that do not come into contact, but whose surfaces may be within a short distance, such as the sleeve -15-. Likewise, the electrical contact materials -17- are selected with 10 characteristics / anticorrosive treatment. It is also preferred that the material of the needle and of the electrical contact be the same or of similar composition, to avoid migration of metal ions through the interface.
    The handle object of the present invention, by dispensing with the external adapter made of metallic materials, prevents the transfer of heavy metals by electrophoresis. On the other hand, the release mechanism allows the removal of the needle without contact by the hand of the operator / physiotherapist, which avoids the health risks associated with an accidental puncture.
    Although the invention has been presented and described with reference to embodiments thereof, it will be understood that these are not limiting of the invention, so that multiple constructive details or other variables that may be evident to the technicians of the sector could later be variable. of interpreting the subject matter disclosed in the present description, claims and drawings. Thus, all variants and equivalents will be included within the scope of the present invention if they can be considered to be within the broadest scope of the following claims.
