Description
1 / 36 Probe and its Use, System and Process of Applying Electromagnetic Signal to Dermal Surface Field of Invention
[0001] The present invention is situated in the fields of medical devices and electromedical equipment intended for skin procedures in the area of, for example, gynecology. Background of the Invention
[0002] The demand for skin modification procedures has spurred the market to produce different equipment with better results and fewer side effects, aiming for greater patient satisfaction. One of the products developed for both clinical and aesthetic purposes is an applicator of electromagnetic signals such as light waves, radiofrequency, and electrostimulation that heat the patient's skin or stimulate it, for example, by remodeling collagen.
[0003] The technique has used radiofrequency applicators in the form of an electromedical handpiece that is held and placed in contact with the skin. With this, the operator checks the temperature at the application site, the temperature being measured by the handpiece while the operator performs repetitive movements of the handpiece over the skin to improve the quality of contact between the handpiece and the skin, providing energy transfer and thermal distribution.
[0004] In this way, radiofrequency emission is used to reduce sagging and promote the formation of new collagen through intense heating of connective tissue and other areas, such as the vaginal canal. On the other hand, the movements of the handpiece in certain regions of the body are uncomfortable, causing discomfort to the patient and embarrassment to the operator.
[0005] Additionally, to reach a specific temperature for the procedure, conventional solutions configure a maximum power, Petition 870250079292, dated 04 / 09 / 2025, page 5 / 58 2 / 36 causing burning sensations perceived by the patient, due to the temperature difference between the skin and the handpiece at maximum power, forcing the skin to abruptly reach the target temperature (setpoint) for the procedure, for example, 44 °C. Furthermore, there are solutions from the previous technique that reach a predefined temperature value (40 or 41°C), but gradually reduce the radiofrequency power to avoid exceeding the predefined temperature and, consequently, do not achieve the expected results.
[0006] Furthermore, conventional handpiece solutions have a disposable outer part that is removed after each application for subsequent cleaning and sterilization of the handpiece. In general, this outer part is disposable, but there are also solutions with a non-disposable outer part and without the possibility of sterilizing the handpiece.
[0007] One of the first handpieces of the prior art is presented in document US20180001103A9 for applying radiofrequency to the vaginal canal using capacitive radiofrequency (RF) electrodes, and for mapping the temperature at that location using thermal sensors.
[0008] Another solution is shown by patent US9713565B2 disclosing an applicator provided with a gripper connected to a treatment plug. This plug has a layer of thermally conductive elements, surrounded by RF electrodes with circular or linear geometries. Next to the surface of the electrodes, there are two temperature sensors. Due to its constructive limitation, US9713565B2 mentions that the applicator reaches up to 80% of the external wall area used for treatment, even when using multiple electrodes. With this high number of electrodes, the applicator requires an internal cooling medium, not to be confused with the present invention.
[0009] Furthermore, the constructive limitation present in the applicator of US9713565B2 is due to the arrangement of the electrodes, which are linear and fixed side-by-side, spaced longitudinally or transversely in the cylindrical applicator. This segmented distribution of the electrodes Petition 870250079292, dated 04 / 09 / 2025, page 6 / 58 3 / 36 implies high current densities, increasing local heating, which causes discomfort to the patient. Thus, for better temperature distribution on the skin, the US9713565B2 applicator requires a series of applicator repositionings by the operator, causing discomfort to both the operator and the patient.
[0010] Subsequently, document WO2020142470 presents a method for treating skin and other patient tissues using RF. For this, the RF applicator has several layers, with two dielectric layers forming a sandwich with a conductive layer. Furthermore, impedance and temperature sensors are used, where a computer maps the impedance in the application region to adjust the radiofrequency power. On the other hand, the device of the present invention does not require an embedded impedance sensor.
[0011] Another RF application device is described in the patent EP3346937B1 describes a selective thermal treatment of vaginal canal areas using resistive radiofrequency technology. EP3346937B1 describes three embodiments with different configurations for internal or external treatments, each sharing the same elongated support equipped with an RF generator. Four or more electrodes are fitted onto this support, interspersed with insulating rings, each electrode having a ring or line shape. Additionally, one of the insulating rings has a pyrometer on its surface for temperature measurement. Bipolar electrodes are generally used, so that the current flows only between each pair of electrodes, remaining confined to the tissue between them.However, the spaced electrodes lead to inefficient heating, resulting in uneven heating, as is the case with the US9713565B2 applicator, while the EP3346937B1 temperature sensor has a field of view limited to the immediate vicinity in front of the sensor.
[0012] Document US11660463B2 discloses a device for treating the vaginal canal using LEDs, high-frequency waves and Petition 870250079292, dated 04 / 09 / 2025, p. 7 / 58 4 / 36 Electrical muscle stimulation (EMS). The device consists of two parts – the main part, which is used for skin contact and is attached to a base that provides sterilization by heating the main part. A linear extension of the base has red and blue LEDs, while the main part has a conical silicone cover connected to a cylindrical body, which receives six RF or EMS electrodes. Similar to the prior art cited previously, the electrodes of the US11660463B2 device are equally spaced 40 to 50 mm apart, causing a reduction in the efficiency of heat exchange.
[0013] In this sense, the aim is to develop more efficient solutions for the application of electromagnetic waves to the skin, which measure temperature with greater precision, provide optimized electromagnetic interaction with the skin and facilitate product sterilization, aiming to provide patient comfort and greater heating efficiency through application more suited to skin contact.
[0014] Thus, as can be inferred from the literature reviewed, no documents were found anticipating or suggesting the teachings of the present invention, so the solution proposed here has novelty and inventive activity compared to the state of the art. Summary of the Invention
[0015] Thus, the present invention solves the problems of the prior art by means of an electromagnetic signal emission probe on a patient's skin, wherein the probe comprises an electrode covering the probe tip to provide optimized heating and electrostimulation to the patient's dermal surface by means of complete contact between the probe tip and the dermal surface.
[0016] Furthermore, the probe is fully sterilizable and controlled by a system that executes specific configurations for signal application, achieving aesthetic effects on the dermal surface. Thus, with the control Petition 870250079292, dated 04 / 09 / 2025, page 8 / 58 5 / 36 and measurement of operating parameters of the sterilizable probe, the invention increases the efficiency and safety of aesthetic procedures, generates data to monitor the evolution of the patient's physical condition and also provides a reduction in probe movement during application, promoting patient comfort and reproducibility of procedures, in a personalized way to achieve results more quickly for the patient.

[0019] In a third object, the invention presents a data acquisition process from the application of electromagnetic signals to a dermal surface by means of a probe (1), the process comprises the steps of: stimulation of the dermal surface by means of a continuous surface electrode (21) disposed in an application region (20) of the probe (1); reading of at least one thermal data point by means of a sensor assembly (51) disposed in the application region (20) of the probe (1); and receiving the read thermal data point by means of a processing unit communicating with the probe (1). Petition 870250079292, dated 04 / 09 / 2025, page 9 / 58 6 / 36
[0020] It is also an object of the invention the use of a probe (1) for applying an electromagnetic signal to reduce flaccidity and attenuate atrophy of a vaginal canal, wherein the use comprises the step of heating the vaginal canal by means of a continuous surface electrode (21).

[0047] The present invention explores the benefits derived from electromagnetic signals applied to the skin by a probe, in an efficient manner, aiming at patient comfort and operator practicality by reducing the need to move the probe during the procedure. To this end, the invention presents a probe (1) for applying an electromagnetic signal to a Petition 870250079292, dated 04 / 09 / 2025, page 11 / 58 8 / 36 dermal surface. For illustrative purposes, the dermal surface is internal or external to the vaginal canal of a patient, without limitation to the scope of the invention, considering that the probe (1) is applicable to other tissues.
[0048] In one embodiment, the electromagnetic signal is a radiofrequency (RF) signal that promotes heating of the dermal surface. In another embodiment, the electromagnetic signal corresponds to the frequency range of visible light that causes both thermal and photochemical effects. In yet another embodiment, the electromagnetic signal is a microcurrent or voltage that causes electrostimulation with the effect of stimulating the dermal surface.
[0049] Thus, the application of the electromagnetic signal contributes to the performance of tissue regeneration in the patient and strengthens the patient's musculature. Therefore, for illustrative purposes, the invention is applicable in the gynecological field, performing procedures for patients with urinary incontinence or tissue flaccidity, strengthening muscles and / or forming new collagen.
[0050] Aiming at patient comfort and the prevention of irritation or allergic reactions, the probe (1) is manufactured with biocompatible materials along its outer periphery. From this, the probe (1) is composed of an application region (20), followed by a transition region (40) and, subsequently, an interface region (30). In one embodiment, the probe regions – application (20), transition (40) and interface (30) – together form a body of substantially cylindrical geometry. For the purposes of the invention, the application region (20) is the end region of the probe (1) for the emission of electromagnetic signals. In one embodiment in the gynecological field, the application region (20) is positioned in the vaginal canal. In one embodiment, the body of the probe (1) allows the insertion of a protective layer over at least the application region (20).
[0051] Subsequently, the transition region (40) is positioned between the application region (20) and the interface region (30). In one embodiment, the transition region (40) is an extension between the application region (20) and the interface region. Petition 870250079292, dated 04 / 09 / 2025, page 12 / 58 9 / 36 (30) of the probe body (1). Additionally, the probe body (1) has locks or fastening mechanisms (42) designed for the secure coupling of the protective layer over the application region (20) and / or transition region (40), minimizing the need for sterilization between patients. In one embodiment, the outer surface of the transition region (40) has these locks as surface recesses (42) that contribute to the fixation of the protective layer to the probe body (1). In one embodiment, the protective layer is a preservative, allowing the probe (1) to be safely reused.
[0052] In one embodiment, the invention enables the use of the protective layer as a disposable film covering the application (20) and transition (40) regions. In one embodiment, the surface unevenness is raised and / or recessed (42) for fixing the film. In this way, the invention reduces the need for sterilization for application of the probe (1) to each patient. Even if some damage occurs to the film, the probe (1) is sterilizable.
[0053] Thus, for complete sanitization of the probe (1), the present invention provides a fully sterilizable probe (1). In one embodiment, the probe (1) is autoclavable. Therefore, the present invention facilitates the sanitization of the probe (1) and does not generate waste, since the probe (1) is entirely inserted into an autoclave. The scope of the present invention does not restrict sterilization to autoclaving only, since the probe (1) of the invention is also sterilizable by the application of ethylene oxide (ETO), gamma radiation, among other forms of sterilization.
[0054] In one embodiment, the probe (1) is manufactured as a single unit using suitable materials, aiming for airtightness and resistance for sterilization by autoclave, ETO or gamma rays. That is, the probe (1) is defined as a monoblock using biocompatible materials with high thermal and chemical resistance, allowing complete sterilization. In one embodiment, a resin surrounds embedded electronic circuits inside. Petition 870250079292, dated 04 / 09 / 2025, page 13 / 58 10 / 36 of the probe (1). Thus, the invention aims to ensure the safety of the application by completely sterilizing the probe (1), preventing cross-contamination.
[0055] Thus, the transition region (40) is an extension of the interface region (30) until it reaches the application region (20). In one embodiment, the periphery of the application region (20) is curved and aligned with the beginning of the transition region (40), providing contact with the dermal surface with less discomfort to the patient. In one embodiment, the periphery of the application region (20) is defined by the electrode (21) that forms an envelope. In one embodiment, the envelope has cylindrical walls and receives a rounded cap (22), in order to prevent discomfort to the patient and lesions on the dermal surface.
[0056] Additionally, the interior of the application region (20) has a sensor assembly (51). Thus, the sensor assembly (51) is housed in the casing to perform a thermal reading through the electrode (21). In this way, the sensor assembly (51) is positioned inside the casing (21) in order to provide a more comprehensive field of view for identifying temperatures on the dermal surface.
[0057] Furthermore, the application region sheath (20) has the electrode (21) occupying most of the surface area of the sheath / application region (20). In one embodiment, the electrode (21) covers one end of the probe (1) continuously. Thus, instead of spaced electrodes or electrodes interspersed with insulating materials, the invention presents a continuous surface electrode (21) that eliminates gaps or insulating parts of the previous technique, in order to increase contact with the skin and, consequently, promote the efficiency of heating or electrostimulation. For the purposes of the present invention, said contact is thermal contact through a gel, protective layer and / or when the probe approaches or touches the dermal surface.
[0058] In one embodiment, the electrode (21) of the probe (1) is the envelope of the application region (20) itself, so that the electrode (21) defines Petition 870250079292, dated 04 / 09 / 2025, page 14 / 58 11 / 36 the entire cylindrical surface of the application region (20) capable of coming into contact with the dermal surface. In one embodiment, the electrode (21) covers the cylindrical sides of the application region (20), providing a 360° angular range for both the emission of electromagnetic signals on the skin and for reading skin temperatures by the sensor assembly (51) inside the electrode (21).
[0059] Additionally, the transition region (40) is elongated and extends from the application region (20) to the interface region (30), where the operator's hand is positioned for manipulation of the probe (1). In one embodiment, the interface (30) and transition (40) regions together form a housing for a transmitter and receiver and other electronic components, defining an electronic circuit (50) connected to the application region (20). In a complementary embodiment, the circuit is connected to a battery.
[0060] Thus, the electronic circuit (50) is connected with the electrode (21) in the application region (20) for emitting electromagnetic signals to the dermal surface. In one embodiment, the electronic circuit (50) is connected with the sensor assembly (51) in the application region (20). In one embodiment, the electronic circuit (50) travels through the transition region (40) to reach the electrode (21) and the sensor assembly (51) located in the application region (20).
[0061] For this, the electrode (21) is coupled to the transition region (40). In one embodiment, the transition region (40) has a contour (44) for mechanical and electromagnetic association with the electrode (21) of the application region (20). In this way, this contour (44) electrically feeds and fixes the electrode (21), which is the enclosure in the application region (20) of the probe (1). In a further embodiment, the transition region (40) has an inner surface provided with an opening for the passage of the electronic circuit (50) that connects with the sensor assembly (51).
[0062] In one embodiment, the aforementioned mechanical and electromagnetic association between the contour (44) of the transition region (40) and the electrode (21) is achieved by fitting, threading, screwing, adhesive bonding, among other forms of permanent or non-permanent union. In one embodiment, Petition 870250079292, dated 04 / 09 / 2025, page 15 / 58 12 / 36 The aforementioned non-permanent joint facilitates maintenance on the probe (1), such as electrode replacement (21) and sensor assembly repair (51). Furthermore, the aforementioned non-permanent joint promotes versatility for the probe (1) by enabling the replacement of the electrode 360°, 180°, among other electrode models, depending on the application.
[0063] At the opposite end from the application region (20), the interface region (30) of the probe (1) has a connector (31) for connecting the probe (1) to an external device. In one embodiment, the external device is an electromagnetic signal source. In a further embodiment, the interface region (30) has an ergonomic shape for proper positioning of the operator's hand. In this way, the interface region (30) provides interaction with the operator, as well as data communication and / or power supply to the probe (1) through the connector (31). In a further embodiment, the end of the interface region (30) receives an optional cap over the connector (31), sealing the probe (1) for sterilization, for example.
[0064] Furthermore, the probe (1) of the invention has, in one embodiment, visual and / or audible indicators (41) located in the transition region (40) to show the operation of the probe (1), for example, heating in progress, reaching a certain temperature, fault alert, etc. In one embodiment, as an alternative or complementary way to the electrode, LEDs and / or other electrical devices are added to the application region (20) for skin stimulation.
[0065] Therefore, the probe (1) of the present invention has at least one electrode that emits electromagnetic signals and is disposed in the application region (20) as described above. In one embodiment, the electrodes are unipolar or bipolar for radiofrequency (RF) emission. With this, the RF signals promote heating of the dermal surface. In one embodiment, the RF signal is capacitive with electrical isolation. In an alternative embodiment, the RF signal is resistive. In another embodiment, the electromagnetic signal is a fractional radiofrequency. Petition 870250079292, dated 04 / 09 / 2025, page 16 / 58 13 / 36
[0066] In an alternative embodiment, the probe (1) applies plasma with helium. In another embodiment, the probe (1) applies pulses for electrostimulation, promoting muscle contraction, for example, of the pelvic region.
[0067] Based on this, the present invention provides the integration and synergy of multiple technologies in one protocol, based on the ability of the probe (1) to combine or sequence different electromagnetic signal modalities. That is, the same probe (1) has the ability to apply the electromagnetic signal technologies mentioned above, so that the operator selects one of them or a sequence of modalities for a more suitable and optimized procedure, with less discomfort to the patient and operator.
[0068] In one embodiment, the probe (1) is an electrostimulation applicator, producing contractions to increase local circulation in order to then apply radiofrequency. In addition, the probe (1) also contributes to increased muscle mass and tissue recovery at the application site.
[0069] Thus, the probe (1) applies electromagnetic signals from the electrode(s) (21) of the application region (20) to the skin. In one embodiment, the electrode (21) is circular and continuous, defining a 360° angle, and the application region (20) is devoid of insulation to increase energy transmission to the skin, whereas an insulating element or layer is commonly used between electrodes in the previous technique. In one embodiment, the electrode (21) is monopolar and cylindrical in shape, and the signals from the probe (1) reach all dermal surfaces surrounding the application region (20) of the probe (1).For the purposes of this example, this implementation is intended for intravaginal RF heating procedures.
[0070] In one embodiment of the electrode (21) being semicircular defining an angle of 180° over the envelope of the application region (20), the signals from the probe (1) reach even more delicate surfaces, for example, the vulva or external areas of the vagina. Petition 870250079292, dated 04 / 09 / 2025, page 17 / 58 14 / 36
[0071] From this, the invention makes it possible to construct the probe (1) with different configurations for the electrode (21), providing a more specific application by the electrode (21) suitable by varying a dimension of the electrode (21). In one embodiment, the variation of the electrode (21) affects the diameter. In another embodiment, the variation of the electrode (21) is relative to the angle occupied by the electrode in the surface area of the enclosure.
[0072] These embodiments do not limit the scope of the invention, since the electrode (21) of the invention is arched, forming a continuous surface that surrounds the sensor assembly (51) within the enclosure in the application region (20) of the probe (1). In this way, the electrode (21) covers, partially or totally, the end of the probe (1) continuously around the enclosure. In these embodiments, the electrode (21) used is monopolar, where the patient lies on a metal plate. Thus, the capacitive displacement between the electrode (21) and the plate provides a greater depth of reach of the electromagnetic signal.
[0073] Alternatively, the probe (1) has two electrodes. In one embodiment, the electrodes are bipolar, so that the periphery of the application region (20) is split and formed by two 180° electrodes defining the envelope, with minimal space occupied by an insulating element disposed between the electrodes. In another embodiment, both electrodes are monopolar, each occupying 180° on the periphery of the application region (20). In these embodiments, the electrodes cover the end of the probe (1) in order to achieve greater electromagnetic interaction with the dermal surface, i.e., heating, electrostimulation, among other ways of transmitting energy to the dermal surface.
[0074] From this, the electrode is configured to emit at least one electromagnetic signal from among: radiofrequency (e.g., capacitive, resistive, non-ablative, or fractional), visible light, microcurrent, voltage for electrostimulation, or plasma with helium. In this way, the invention provides the ability for a single probe to be compatible with multiple modalities. Petition 870250079292, dated 04 / 09 / 2025, page 18 / 58 15 / 36
[0075] Still in the application region (20), the temperature sensor assembly (51) is housed, which reads at least two points associated with the electrode (21). In one embodiment, the temperature sensor is optical and digital. In one embodiment, the temperature sensor is a radiometer that eliminates the need for physical contact with the dermal surface.
[0076] Additionally, in one embodiment, the sensor assembly (51) has two sensors arranged within the application region (20). In one embodiment, the two sensors are arranged in opposite positions relative to the center of the application region (20). In another embodiment, the sensor assembly (51) has four temperature sensors. In the embodiment of two sensors of the assembly (51), these are positioned on opposite faces of the electronic circuit board (50). In these embodiments, the quantity does not restrict the scope of the invention, provided it is greater than one, whereas the prior art is limited to only one sensor and thus restricts the field of view of the probe.
[0077] In one embodiment, the same temperature sensor is connected to two distinct points of the application region (20), receiving temperature readings from both points. Thus, from the temperatures of two or more points distributed in relation to the electrode surface (21), the invention allows the identification of the thermal distribution along the dermal surface that surrounds the application region (20).
[0078] That is, the integral thermal distribution of the dermal surface is detected by the sensor assembly (51) which reads skin temperatures through the curved surface of the electrode (21) in the application region (20). With the electrode (21) reaching a greater perimeter of the vaginal canal than that achieved by the previous technique, the invention enables a more complete and faster procedure by providing higher quality skin contact, since the probe (1) has a larger application area through the continuous surface electrode (21). Furthermore, the continuous surface electrode (21) provides a wide field of view for the sensor assembly (51) to perform the reading of Petition 870250079292, dated 04 / 09 / 2025, page 19 / 58 16 / 36 temperatures, providing parameters for robust control of signal emission by the probe (1). With this, the invention eliminates the need for repetitive movements of the previous technique, which cyclically repositioned the probe. Furthermore, by identifying the thermal distribution, the system of the invention acts to provide a more efficient application through robust control and identification of failures during application, for example, reduced contact quality.
[0079] Thus, the present invention allows the reduction or even elimination of cyclical movements, producing a fixed application protocol with benefits to the patient and the operator due to less discomfort during application. In one embodiment, the probe (1) is fixed to a pedestal support. Furthermore, the position of the pedestal support is adjustable.
[0080] Thus, considering that the previous technique presents as standard the mobile application protocol to cyclically reposition the probe in the vaginal canal, the invention provides the fixed application protocol, even though the mobile one is possible. In this way, the invention promotes ergonomics for the operator, who exerts less effort. Furthermore, from the fixed application, the invention enables reproducibility of the data collected by an application monitoring system and, consequently, promotes the reproduction and monitoring of the procedure, which, in many cases, requires more than one application or session.
[0081] In this sense, the present invention presents the use of the probe (1) with the objective of reducing the flaccidity of a dermal surface, more specifically, the vaginal canal, the probe (1) being as described above. Thus, the use of the probe (1) has aesthetic purposes with collagen remodeling. In addition, many oncological treatments cause vaginal atrophy. Therefore, the use of the probe (1) also attenuates the atrophy of the vaginal canal.
[0082] For this, the use of the probe (1) involves the step of warming the vaginal canal with the introduction of the probe (1), which has the electrode (21) of Petition 870250079292, dated 04 / 09 / 2025, page 20 / 58 17 / 36 continuous surface for emitting electromagnetic signals. The electrode (21) covers the end of the probe (1) and receives a cap (22) at the tip of the probe (1) forming an enclosure in the application region that has the sensor assembly (51) inside. In one embodiment, the electrode (21) surrounds the sensor assembly (51).
[0083] From this, the use also presents the step of monitoring the thermal distribution of the vaginal canal, based on the data read by the sensor set (51). In one embodiment, the monitoring is carried out through indicators on the probe itself (1) and / or on a display connected to an external device. Even though it is intended for aesthetic applications, the use of the probe (1) is able to prevent urinary incontinence by increasing an additional temperature difference to achieve effects in the urethra.
[0084] Thus, for the emission of electromagnetic signals, in one embodiment, the probe (1) has its own power supply. In another embodiment, the probe (1) is electrically powered by an external device that connects to the probe (1) via the connector (31) in the interface region (30).
[0085] From this, the invention presents, among one of its objects, a system for applying signals to the dermal surface, for example, vaginal canal, vulva, among other tissues. The system has the probe (1) of the invention as described above, as well as a source of the electromagnetic signal connected to the probe (1). In one embodiment, the source provides different options of electromagnetic signals, such as RF and electrostimulation, so that the operator chooses one of the options or a specific sequence of signals.
[0086] Furthermore, a processing unit is part of the system of the invention. The processing unit acquires the thermal data read by the sensor assembly (51) of the probe (1). In one embodiment, the processing unit has a receiver and transmitter of said data. In this embodiment, the processing unit relays the data read to a Petition 870250079292, dated 04 / 09 / 2025, page 21 / 58 18 / 36 control unit. In another embodiment, the processing unit processes the data read for subsequent sending of information related to the thermal data to the control unit. In one embodiment, the processing unit is part of the electronic circuit (50) of the probe (1). In another embodiment, the processing unit is embedded in an external device.
[0087] For this purpose, the sensor assembly (51) is housed in the application region (20) and is connected to the circuit board (50), where the processing and control units are also connected, in one embodiment. In another embodiment, the control unit is embedded in the external device that communicates with the probe (1) via the connector (31), in addition to powering the probe (1) as it is provided with the signal source.
[0088] Thus, the invention presents a data acquisition process from the application of electromagnetic signals to a dermal surface by means of a probe (1). In one embodiment, the system of the invention implements said process.
[0089] The process has the following steps: heating the dermal surface by means of an electrode covering one end of the probe (1); reading at least one thermal data point by means of a sensor assembly (51) contained in said electrode (21); and receiving the read thermal data point by means of a processing unit located in the probe (1).
[0090] In one embodiment, the signal used is radiofrequency (RF) for heating. In an alternative embodiment, the data acquisition process applies to electrostimulation of the dermal surface. In the RF embodiment, the process features a control unit where the operator configures parameters for RF application, such as power, temperature, application duration, and thermal dwell time. In one embodiment, the control unit has a pre-configuration of parameters to facilitate selection by the operator.
[0091] Next, the sensor assembly (51) performs the reading of Petition 870250079292, dated 04 / 09 / 2025, page 22 / 58 19 / 36 temperatures on the dermal surface and sends them to the processing unit which communicates with the control unit. In one embodiment, this communication is carried out wirelessly.
[0092] In this way, the processing unit transmits information related to thermal data to the control unit, which obtains feedback from the application. In one embodiment, said information correlates a temperature with the position read, considering that the sensor assembly (51) has at least two temperature sensors arranged inside the electrode (21) of the probe (1). In one embodiment, said information, correlated to thermal data, is transmitted intermittently or upon request from the control and / or processing unit.
[0093] Based on this information, the control unit manages the probe parameters (1) to provide an appropriate application and display application indicators via a display, for example. Furthermore, in one embodiment, the processing unit communicates with indicators on the probe (1) to notify certain application settings, such as actual or maximum temperature and power.
[0094] The examples shown here are intended only to illustrate one of the numerous ways of carrying out the invention, however without limiting its scope. Example 1 - Electromedical Handle
[0095] This example presents an electromedical handpiece (1) equipped with high-precision temperature sensors and an integrated control system. The temperature sensors (51) are in opposite positions inside the head portion (20) provided with the electrode (21) covering the rounded sides of the head portion (20). For the example, without restriction to the scope of the invention, the temperature sensors (51) have an accuracy of ±0.1°C.
[0096] The handle (1) is made with biocompatible materials and Petition 870250079292, dated 04 / 09 / 2025, page 23 / 58 20 / 36 ergonomic, being designed to be comfortable during prolonged use. The handle (1) also has a plastic connector (31), minimizing the risk of electric shock to the patient.
[0097] The handle body (1), shown in figure 1, has a cylindrical rod shape with variations in cross-sectional diameter along the length of the probe (1). From left to right in figure 1, the handle body (1) has the head portion (20), followed by an extension (40) until it reaches a grip portion (30).
[0098] The grip portion (30) has curves for better positioning of the operator's hand, aiming to promote ergonomics for the handle (1) of the invention.
[0099] The extension (40) extends from the grip portion (30) to the head portion (20). The extension (40) has grooves / reliefs (42) both at the end adjacent to the grip portion (30) and at the end adjacent to the head portion (20). Thus, these grooves (42) form locking mechanisms for attaching a condom to the body of the handle (1), providing safety in the reuse of the handle (1). Additionally, the grooves (42) receive elastic rings positioned over the condom.
[0100] Still on the extension (40) shown in figure 3, there are LEDs (41) on its surface to indicate the operation of the handpiece (1), so that they light up, flash and / or turn off according to a determined parameter value (power, application time and temperature). Closer to the head portion (20), the surface of the extension has a marking (43) referring to a safe limit for the insertion of the handpiece (1), without causing major discomfort to the patient. In the gynecological field, this limit is standardized as 7 cm, for example. Following this, there is also a centralized recess (42) next to the annular groove (42) to facilitate the removal of the condom.
[0101] Next, the handpiece (1) finally presents the electrode (21) which makes up the head portion (20) for radiofrequency (RF) emission. The beginning of the extension (40) follows, in an aligned manner, the surface of the Petition 870250079292, dated 04 / 09 / 2025, page 24 / 58 21 / 36 circular electrode (21). In the example, without restriction to the scope of the invention, the electrode is monopolar. Additionally, the electrode (21) has cylindrical walls that receive a rounded cap (22) disposed at the end of the handle (1). For this, the cap (22) is fitted onto the electrode (21), for example, by screwing and / or gluing.
[0102] For example, the electrode (21) is manufactured using a sheet of metallic material, for example, aluminum. Then, the electrode (21) undergoes an anodizing process, which forms an oxide layer on the surface of the electrode (21) that is electrically and thermally insulating to protect the tissue in physical contact with the electrode (21). Thus, the electrode (21) is a single-body, monopolar electrode with an annular and continuous geometry, capable of generating the RF electric field in a capacitive manner for the entire dermal surface around the head portion (20), consequently promoting the quality of contact between the electrode and the dermal surface.
[0103] In the cutaway shown in figure 4, it can be seen that the handle (1) houses a printed circuit board (50) running from a socket (31) fixed to the tip of the board (50) in the grip portion (30) to the opposite tip in the head portion (20), passing through the extension (40). Thus, the handle body (1), manufactured as a single piece, is fully sterilizable, so as to promote safe use, although the handle (1) can also receive condoms for safe use. In this example, the handle body (1) is made of epoxy resin.
[0104] The plate (50) is also shown in figures 5 to 7, highlighting the two temperature sensors (51), one on each side of the plate (50). These sensors are housed in the head portion (20), more specifically, inside the electrode (21) at the tip of the plate (50) that passes through the surface of the end of the extension (40). With this, the electrode (21) provides a large surface area for RF emission through the cylindrical walls forming 360°. Furthermore, the electrode (21) provided with the continuous surface also provides a 360° field of view for the temperature sensors (51) arranged in Petition 870250079292, dated 04 / 09 / 2025, page 25 / 58 22 / 36 opposition in relation to plate (50).
[0105] From this, figure 8 illustrates an exploded view, where the probe body (1) is a single block formed by the handle portion (30) plus the extension (40) which receives the head portion (20) defined by the electrode (21). The electrode (21) in the example is screwed into the contour (44) of the extension (40) which provides both the fixation of the electrode (21) and its electrical power supply for RF emission.
[0106] Figures 9 and 10 show the end of the plate (50) having the temperature sensor (51) inside the contact portion (20) with the electrode (21). In addition, the beginning of the extension (40) has the contour (44) of mechanical and electromagnetic association with the electrode (21). This contour (44) is an external thread for the example.
[0107] From this, the invention promotes efficiency for heating by means of the electrode covering the end of the handle (1), in addition to achieving greater precision of application by capturing temperatures in a wide field of view by means of the sensors (51) on opposite sides.
[0108] With this amplitude of RF emission area through the electrode (21), the invention promotes efficiency in application, achieving a series of benefits in relation to the handpieces of the previous technique, both for the operator and the patient, so that the procedure is faster, more comfortable for the patient and less embarrassing for both, since the cyclical back-and-forth movement of the handpiece (1) for repositioning and quality of contact is no longer necessary. Thus, the invention contributes to the execution of aesthetic procedures in tissues, such as the vaginal canal, vulvar applications and labia majora, among other dermal tissues.
[0109] Furthermore, Figure 11 shows one end of the handle (1) corresponding to the position of the socket (31) in the grip portion (30), for connection with external devices, for example, signal source and controller. At the opposite end of the handle (1), there is the electrode (21) in the head portion (20), which is shown in Figures 12 and 13. The side of the electrode (21) with Petition 870250079292, dated 04 / 09 / 2025, page 26 / 58 23 / 36 free opening has an internal thread (23) for coupling to the external thread (44) of the extension (40). The opposite side of the electrode (21) has, from an internal wall connected to the cylindrical walls, a thread for receiving the cap (22).
[0110] Furthermore, figure 14 shows another view of the handle (1) of the invention, which is also embodied as the handle (1) shown in figures 15 to 17. Figure 17, in particular, shows the flattening of the extension (40) in relation to the head (20) and grip (30) portions.
[0111] With the circular arrangement of the electrode (21) and with the positioned temperature sensors (51), the invention reduces discomfort to the patient and embarrassment to the operator by eliminating the need to move the handle (1) back and forth, for example, inside the patient's vagina. Example 2 - Handle Control and Monitoring System Electromedical
[0112] Tissue heating can produce three main effects: (i) unwanted thermal damage, if heating is excessive; (ii) induction of programmed cell death, when controlled under certain conditions; or (iii) stimulation, which generates thermal discomfort in the tissue, triggering biological processes of collagen remodeling, this iii) being the objective of the handpiece (1) of the present invention.
[0113] Collagen remodeling can be achieved with heating at temperatures of approximately 38-42°C, during aesthetic sessions of 2 to 6 minutes, for example. Controlled temperature increase can also be used in treatment protocols for urinary incontinence, due to the regenerative stimulation in vaginal and periurethral tissue. The difference between the types of procedure lies in the application temperature related to the dermal surface, which in the case of the vaginal canal, can reach the urethra in a controlled manner.
[0114] To this end, the control system has a processor that receives data from the sensor assembly (51). For the purposes of this Petition 870250079292, dated 04 / 09 / 2025, page 27 / 58 24 / 36 invention, the processor and the processing unit are capable of receiving and interpreting information in order to execute control algorithms and generate diagnostic data for application monitoring.
[0115] In one embodiment, the processor receives temperature data read by the sensor assembly (51) embedded in the probe (1). Thus, one of the operating parameters is the temperature of the points associated with the electrode (21) of the probe (1) and / or the dermal surface.
[0116] In one embodiment, the processor transmits temperature data to a monitoring system, which returns other operating parameters.
[0117] In one embodiment, the operating parameter is: a probe data point (1); and / or a dermal surface data point. The probe data point (1) refers to: a temperature, a radiofrequency power, an accumulated energy or a dose of the application, an application time and / or a warm-up time. The dermal surface data point refers to: an impedance, contact quality, probe position (1) and patient data (age, application site, etc.).
[0118] Based on these parameters, the system executes control configurations, aiming for application efficiency. In one embodiment, the control configuration is a temperature variation operation. In one embodiment, this temperature variation is positive.
[0119] In this way, to achieve a temperature suitable for the procedure, the invention allows heating in incremental steps, performing each increment after the thermal accommodation of the previous increment, preventing burning sensation and discomfort to the patient. In one embodiment, at each increment, the operator asks the patient about the level of tolerance of thermal sensation before increasing the temperature. In another embodiment, the increments are automatic as long as the control system knows the patient's data or identifies the specifications of the dermal surface.
[0120] Considering that different impedances of the dermal surface Petition 870250079292, dated 04 / 09 / 2025, page 28 / 58 25 / 36 require different application powers, the present invention provides an efficient procedure, customized to each patient during the evolution of the procedure, delivering more energy in less time with safety for the procedure.
[0121] Additionally, the control system has an indicator (41) that receives operating parameters from the processor and / or the sensor assembly. In one embodiment, the indicator is an LED (41) attached to the probe (1) showing actual parameters during application, for example, temperature and contact quality. In a further embodiment, the indicator emits an alert when the operating parameter is outside a predetermined range. In one embodiment, the indicator is a display.
[0122] These operating parameters are stored and made available to the operator in the control system itself and / or on an external device, for example, a cloud or monitoring system.
[0123] Furthermore, the invention provides a monitoring system for the application of an electromagnetic signal on a dermal surface. In one embodiment, the monitoring system is implemented on an external operator assistance platform. In another embodiment, the monitoring system is a remote platform.
[0124] For this purpose, the monitoring system has a central unit that connects wirelessly to the probe (1). With this, the central unit receives operating parameters collected by the probe (1) and sends them to an output unit.
[0125] In one embodiment, the monitoring system is software having the central unit and the output unit as part of a computer program. From this, in one embodiment, the parameters collected by the probe (1) are input data received by the central unit.
[0126] Subsequently, in one embodiment, the output unit processes the input data and, based on this, generates results for the application protocol. In one embodiment, the output unit calculates Petition 870250079292, dated 04 / 09 / 2025, page 29 / 58 26 / 36 means and standard deviation with respect to: temperature and power supplied to the dermal surface; and / or actual temperature and power.
[0127] In one embodiment, the result generated by the output unit is: diagnostic information; an application control setting; and / or an operating parameter. Thus, the present invention provides real-time monitoring making said results available to assist the professional in diagnosing and monitoring the procedure's progress, and to provide feedback to the probe control system (1).
[0128] For contact quality identification, the monitoring system has an impedance analyzer. Alternatively or redundantly, contact quality is identified from the power delivered and the temperatures read by the probe sensors (1). In the event of poor contact, the result is a repositioning guide for the probe (1) in order to improve the probe contact (1), based on the data obtained by the impedance analyzer and / or the temperature sensors. In one embodiment, said guide is presented by the indicator, visually and / or audibly. Nevertheless, the invention allows for a reduction in the need for repositioning due to the constructive aspect of the probe (1) provided with the continuous surface electrode.
[0129] To this end, the output unit performs calculations automatically or provides tools for interaction with the operator. In one embodiment, the monitoring system has a user interface for inputting information and displaying results.
[0130] From this, in one embodiment, the output unit detects possible faults that cause poor contact and consequent supply of energy below expected. In one embodiment, the output unit identifies: formation of an air bubble created in the condom; lack of effort by the operator; lack of gel or glycerin; and / or inadequate positioning of the contact region (21) with the electrodes on the skin.
[0131] These parameters are calculated based on the protocol of Petition 870250079292, dated 04 / 09 / 2025, page 30 / 58 27 / 36 fixed application, which enables the temporal evaluation of the thermal distribution, impedance, and power of the radio frequency signal. Additionally, the output unit transmits control settings and operating parameters to the control system, so that it considers a plurality of variables relevant to the system involving the probe and the dermal surface.
[0132] In addition to the aforementioned results, diagnostic information is also provided by the output unit. In one embodiment, the diagnostic information comprises a report with the operating parameters conducted during the applications, forming a history for each patient. In one embodiment, the diagnostic information shows the degree of vascularization at the dermal surface site, based on the impedances obtained. Thus, the present invention allows monitoring of the procedure's progress.
[0133] Among the results, other diagnostic information is obtained by the monitoring system, in order to guide and adjust the operating parameters, whether in the preparation of the application, during the application or after the application, evaluating the responses of the tissue subjected to the procedure.
[0134] Thus, the invention provides monitoring of temperature, impedance, applied and dissipated power, stored energy and settling time. With this, the monitoring system interprets these parameters to generate guidance and execute algorithms in the probe control system (1).
[0135] For the purpose of exemplifying diagnostic information, the monitoring system provides measurements of the patient's pelvic contraction. In one embodiment of the probe (1) identifying that the dermal surface has reached a certain temperature, the monitoring system verifies the time spent at that specific temperature, analyzing the tissue behavior. Also in this embodiment, the monitoring system is able to detect minute oscillations that indicate an adequate response to the procedure. Such oscillations refer to temperature and / or to Petition 870250079292, dated 04 / 09 / 2025, page 31 / 58 28 / 36 dermal surface impedance.
[0136] Additionally, the monitoring system compares the power supplied in the same application session or between different application sessions. In a given application of the probe (1) to the same patient or to patients with similar physiological capabilities, when the monitoring system verifies that the probe (1) needs to supply more power than in previous sessions to reach predefined temperatures, the monitoring system indicates that more power is being dissipated by the dermal surface.
[0137] Thus, the increase in dissipated power reflects the improvement in vascularization at the application site. Alternatively or complementarily, the monitoring system evaluates the accumulated energy, thermal accommodation time, and total application time to obtain a diagnosis of tissue vascularization, thus tracking the evolution of the procedure. In this way, the invention provides a solution for detecting tissue vascularization in a simple and efficient manner, providing greater access to this type of examination, since conventional solutions demand a high cost.
[0138] Furthermore, all this data on parameters, settings, and diagnostic information feeds into a database. With this database, artificial intelligence tools implemented in the monitoring system help optimize the application and provide greater patient comfort.
[0139] Thus, the invention presents a method for applying an electromagnetic signal to a dermal surface, the process comprising the steps of: arranging a contact region (20) for a probe (1) for applying an electromagnetic signal to the dermal surface; reading the temperature of the contact region (20) using the sensor assembly (51); determining at least one result using an output unit; indicating at least one operating parameter of the probe (1) using an indicator (41); and Petition 870250079292, dated 04 / 09 / 2025, page 32 / 58 29 / 36 execution of at least one application control configuration by means of a processor, in which the determination and execution steps are based on the operating parameters of the probe (1). In the LED embodiment (41), the probe (1) has a blue LED that flashes when RF emission is occurring; and a yellow LED indicating that the maximum or setpoint temperature has been reached.
[0140] In one embodiment, the method of the invention is implemented by the probe (1) which, as defined above, has an integrated control system connected to the monitoring system. Thus, the invention reduces the application and movement time of the probe (1), for example, in the vaginal canal, decreasing discomfort to the patient and embarrassment to the operator.
[0141] The invention allows the procedure using both fixed and mobile applications. The fixed application allows for more reliable acquisition of operating parameters, which form the basis for automatic control of the probe (1) and diagnostic guidance.
[0142] For this, the operator positions the probe (1) on the dermal surface, without the need for rotational or back-and-forth movements to provide thermal distribution. Optionally, the operator uses a pedestal support to hold the probe (1) in position with the possibility of position adjustment, collecting operating parameters, for example, temperature of the contact region (21), without the need for movement or repositioning of the probe (1).
[0143] With this, the control system delivers radiofrequency power to the dermal surface via the electrode (21) of the probe (1), based on said parameters. Additionally, the method has parameter indication for easy access by the operator, in visual and / or audible form. From this, the control system increases the temperature, in steps, verifying the response of the dermal surface and the patient's tolerance to the thermal sensation.
[0144] Furthermore, the monitoring system provides parameters, for example, surface impedance data, assembling a picture of Petition 870250079292, dated 04 / 09 / 2025, page 33 / 58 30 / 36 self-diagnosis. In a concrete example, the diagnostic chart shows the level of local vascularization and responses of the dermal surface to specific temperatures and intensities.
[0145] Thus, the invention enables a fixed procedure with monitoring performed by software that connects to the handpiece (1) via Bluetooth. With this, data collected by the handpiece (1) are received by the software in real time, both to generate detailed reports and to provide immediate feedback to the operator and the probe control system (1). Furthermore, the software is implemented on an external device, for example, a tablet or a computer. An embodiment of the handpiece (1) is shown in Figure 18.
[0146] The control system also receives temperature data that forms the basis of advanced automatic temperature adjustment algorithms, aiming to guarantee safety limits and thermal comfort for the patient, in addition to complying with current legislation and standards.
[0147] That is, the probe (1) equipped with two temperature sensors (51) makes it possible to identify the region of the electrode that may be hotter or colder. Thus, the control system communicates with an LED display to indicate the actual skin temperature and visual and / or audible alerts for temperatures outside the appropriate range. In addition, the display also guides the positioning of the handpiece for better thermal contact or better efficiency in the procedure.
[0148] With the fixed application of the handle (1), it is possible to acquire variables, for example, impedance and tissue conductivity, due to the stability of the probe (1) during application. Considering the contact area of the electrode (21), the invention also allows smooth adjustment movements of the probe (1), without causing interference in the application or discomfort to the patient.
[0149] From this, the software shows the evolution of the procedure, as well as possible deficiencies in the execution of the method, whether due to poor Petition 870250079292, dated 04 / 09 / 2025, page 34 / 58 31 / 36 positioning of the handpiece (1) or due to lack of coupling medium with gel. That is, the system indicates and guides a better way to conduct the procedure to obtain maximum thermal delivery in less time safely. Furthermore, with the fixed application protocol, the system facilitates application and promotes repeatability of results.
[0150] Through the control system, the temperature is increased in steps for the procedure applied to dermal surfaces, providing comfort to the patient, including in areas with high tissue sensitivity, for example, the vulva of the vagina. Thus, periodically, the temperature is raised to a certain value, being maintained for a certain time for the patient's thermal comfort. This thermal accommodation time of the tissue can be customized by the operator and / or by the software that recognizes the patient and their preferences.
[0151] To reach a maximum temperature of 44°C, the control system in the example activates the probe (1) up to 38°C and maintains that temperature for 30s to 1 min. Subsequently, the control system repeats the increments to the 40°C step, then to the 42°C step, and finally to the 44°C step. Thus, the control system practically eliminates the sensation of burning for the patient. Furthermore, the accommodation time interval is adjusted by the operator, even being set to zero, considering the thermal tolerance of each patient and the safety of the operation.
[0152] With this, the invention provides a more pleasant application, especially for patients sensitive to rapid heating, allowing the physician to reduce the maximum power and make the procedure gentler, without compromising the effectiveness of the procedure. Furthermore, the control system is able to customize the maximum radiofrequency (RF) output power through automatic control or adjustment via the interface. For the example, the interface is a screen on the external device.
[0153] With this, the probe (1) performs aesthetic procedures in the vaginal canal. Thus, the use of the probe (1) reduces tissue laxity and attenuates atrophy. Petition 870250079292, dated 04 / 09 / 2025, page 35 / 58 32 / 36 of the vaginal canal. For the treatment of urinary incontinence, for example, a higher temperature is applied (e.g., 45°C) to achieve effects on the patient's urethra.
[0154] Thus, the invention allows for the configuration of higher power for a longer time, reaching higher temperatures in deeper tissues and a larger volume of treated tissue, stimulating collagen production and tissue restructuring. In other words, procedures with the probe of the invention are more effective due to the increase in average RF power throughout the procedure and the consequent reduction in procedure time.
[0155] In addition to the RF module, the probe (1) has a plasma module with independent outputs, providing power between 80 and 200 W. Furthermore, the control system obtains tissue impedance values, indicating the best way to deliver power. With this, the software calculates average, maximum, minimum and standard deviation values of the impedance.
[0156] From this, the software collects data from the application in real time, displaying temperature graphs and generating alerts for the control system when it identifies operating parameters that are above or below acceptable limits.
[0157] Furthermore, monitoring the parameters provides information for evaluating the progress of the procedure, assisting the healthcare professional in deciding whether to continue with the procedure. However, the conventional technique usually performs a visual and qualitative assessment. Instead, the invention provides a quantitative assessment, increasing the reliability and efficiency of the procedure results for the patient.
[0158] For this purpose, the information is based on predefined patterns and patient data history, generating reports that can be integrated into an electronic medical record.
[0159] One piece of information is based on the measurement of tissue quality (TQM), enabling quantitative monitoring of the evolution of tissue conditions. Furthermore, the software provides results such as, for example, conditions Petition 870250079292, dated 04 / 09 / 2025, page 36 / 58 33 / 36 of the tissue, vaginal anatomy, probe positions for greater or lesser quality of contact, lack of lubrication with gel, a particular type of condom that is more suitable for securing the probe.
[0160] All this data forms a history linked to the patient and the materials and parameters used in the application. In addition to being useful to healthcare professionals, these histories can be used to aggregate a database used by artificial intelligence (AI) tools. The invention's software has said AI tool to interpret data and generate a diagnosis of the evolution of the patient's physical condition.
[0161] For this purpose, the database stores:
[0162] i) average power used throughout the procedure, including maximum and minimum values used;
[0163] ii) total energy and the fractions required for the heating and maintenance phases during the maximum temperature period;
[0164] iii) average impedance, in addition to the maximum, minimum and standard deviation values; and
[0165] iv) time required for the heating phase, total duration of the procedure, in addition to thermal settling times.
[0166] Figure 19 shows different probes (1) varying in diameter, maintaining shape and length, being used in different functionalities for temperature reading and tissue impedance measurement. From top to bottom, the first probe is a 360° gynecological radiofrequency handpiece with a 30 mm electrode (21).
[0167] This first probe has twice the electrode size compared to probes of the prior art, offering a circular electrode (21) 45mm long, reaching 70 to 80% of the vaginal canal. As the electrode (21) of the invention is detachable, the probe (1) has a variety of applications for different tissues.
[0168] Thus, the second probe in figure 19 is a 360° gynecological radiofrequency handpiece with a 25 mm electrode (21) for the canal. Petition 870250079292, dated 04 / 09 / 2025, page 37 / 58 34 / 36 vaginal. While the third probe is a gynecological radiofrequency handpiece with a 180° electrode for procedures on the vulva and labia majora. Also, thinner probes (1) are used for procedures to attenuate vaginal canal atrophy.
[0169] Figure 20 shows monitoring displayed for different procedures performed by the probe (1) of the invention, where each monitoring graph shows the total time for the procedure, power during the heating and temperature maintenance phases, as well as the energy transfer. Comparatively, the procedure related to the graph on the right shows that there was less energy and power consumption during the temperature maintenance phase, even though the energy consumed was greater during the heating phase. From this, this monitoring allows for evaluations of the procedure (e.g., power and gel used) and evaluations of the dermal surface, such as the patient's condition and evolution. Thus, the invention reduces the power dissipated during both the heating and temperature maintenance phases.
[0170] Furthermore, the power dissipated during applications is evaluated by the software. For example, if a reduced power is sufficient for the skin to reach a certain temperature, then the power dissipated by the skin due to its vascularization is not satisfactory compared to pre-established healthy levels. The level of dissipated power and / or vascularization can also be verified directly by the operator by viewing the operating parameters.
[0171] In this way, the software evaluates the operating parameters that indicate the responses of the dermal surface to the procedure. These responses map the behavior of each patient so that the professional can monitor the progress of the procedure.
[0172] Thus, the invention offers evaluation of both energy dissipation related to vascularization and impedance related to handpiece positioning. There is also a correlation between these Petition 870250079292, dated 04 / 09 / 2025, page 38 / 58 35 / 36 assessments, but the present invention is able to discern tissue responses and probe contact failures.
[0173] Thus, for example, vaginal canal tissue with deficient vascularization implies a lack of lubrication of the canal, compromising the patient's sexual life. Furthermore, other physiological capabilities can be detected by the invention, such as the quality of the tissue, whether it is hydrated or not.
[0174] Thus, the invention contributes both to decision-making about the procedure and to the preparation of applications, establishing conditions for better application, recommending water intake before application, for example.
[0175] Figures 21 and 22 illustrate the different probes (1) shown in Figure 19, where the electrode (21) is disassembled from the probe body (1) as shown in Figure 23, including the cap (22) disassembled as per electrode (21) on the far left. Also in Figure 22, the first two probes (1) on the left have 360° electrodes for applications in the vaginal canal, while the probe (1) on the right has a 180° electrode for vulvar applications.
[0176] Furthermore, the invention makes it possible to identify errors in the execution of the procedure, for example, the improper placement of the condom on the electrode (21). In Figure 24, the electrode (21) on the left shows bubbles between the condom and the electrode (21), compromising the quality of contact. The identification of this procedural error is carried out by monitoring the application parameters, so that the electrode on the left provides an application showing high impedance values, which indicates low contact quality or incorrect assembly of the condom, impairing heat transfer and consequently affecting the RF procedure. The electrode on the right provides better contact quality, so that the condom is uniformly adhered to the electrode surface, this quality being evaluated by low impedance values, in order to accelerate the tissue heating procedure.
