The existing micro-needle therapeutic apparatus is used for performing radio frequency therapy on the deep layer of skin after the micro-needle 400 is penetrated into the skin by connecting the micro-needle 400 with a radio frequency power supply. In order to ensure the treatment area and the treatment effect, the microneedles 400 are generally provided with a plurality of microneedles, and the radio frequency power supply is connected to other parts such as a reciprocating assembly for driving the microneedles 400 to extend and retract, and is also connected to a plurality of microneedles 400. By the arrangement, the microneedle therapeutic apparatus is more complex in structure, the difficulty is increased for production, and the production cost is increased.
Referring to fig. 1 to 8, the present invention discloses a microneedle therapeutic apparatus, which includes a therapeutic apparatus body 100, a first electrode plate 200, at least one microneedle 400, a radio frequency power source and a second electrode plate 300; the first electrode plate 200 is arranged at the end of the therapeutic apparatus body 100, the first electrode plate 200 has a therapeutic surface 220, and at least one through hole is arranged on the therapeutic surface 220; at least one microneedle 400 is arranged in the through hole in a one-to-one correspondence and in a telescopic manner; the radio frequency power supply is connected with the second electrode plate 300 and the first electrode plate 200; during treatment, an electric field is formed between the first electrode plate 200 and the second electrode plate 300, so that a high-heat region 410 is formed at the periphery of the microneedle 400.
In particular, the microneedle therapy device can treat various skins, such as facial skin, underarm skin, and hip skin. The number of the microneedles 400 may be 1 or more, and may be selected according to the treatment site. Accordingly, the number of through-holes is equal to the number of the microneedles 400. The electric field may be directed from first electrode plate 200 toward second electrode plate 300, or may be directed from second electrode plate 300 toward first electrode plate 200.
Referring to fig. 1 and 3, the therapeutic apparatus body 100 further includes a needle plate 500 and a reciprocating assembly 600, the needle plate 500 is used for fixedly mounting the microneedles 400, the reciprocating assembly 600 is disposed behind the needle plate 500, and the reciprocating assembly 600 is connected to the driving assembly so as to drive the microneedles 400 to move telescopically along the through holes 210.
It will be appreciated that the needle plate 500 is provided with a pinhole sized to fit the diameter of the microneedles 400. The micro-needle 400 is arranged in the through hole 210 on the treatment surface 220 of the first electrode plate 200, and in order to flexibly control the micro-needle 400, the micro-needle 400 can make telescopic motion along the through hole 210 through the reciprocating assembly 600, so that the depth, time, frequency and the like of the micro-needle 400 penetrating into the skin can be specifically controlled according to a treatment scheme and a treatment position. So set up, improved the suitability of micropin therapeutic instrument.
The shape of the first electrode plate 200 may be various, and may be regular irregular patterns such as square, rectangle, and circle. The treatment surface 220 of the first electrode plate 200 is used to be attached to the skin, and the microneedles 400 protrude from the through holes 210 of the treatment surface 220 to penetrate into the skin, thereby performing heat treatment on the skin. The second electrode plate 300 may be various, and may be a fan, a square, a rectangle, a circle, etc., all of which are possible.
Please refer to fig. 1 to 5, for example: when an arm is treated, the treatment surface 220 of the first electrode plate 200 is placed on one side of the arm, the second electrode plate 300 is placed on the other side of the arm, the radio frequency power supply transmits radio frequency current to the first electrode plate 200 and the second electrode plate 300, an electric field is formed between the second electrode plate 300 and the first electrode plate 200, the microneedle 400 penetrates into the skin, and meanwhile, the microneedle 400 remarkably changes heat distribution in the electric field to enable heat to be concentrated around the tip of the microneedle 400, so that a high-heat region is formed. This is mainly due to the edge effect, because the microneedles 400 change the potential distribution of the electric field region, causing a sudden change in the potential around the microneedles 400, which increases the electric field gradient at that location. The intensive electric force near the microneedles 400 causes a sharp increase in current density around them, and a significant concentration of thermal field, resulting in a high thermal zone. The microneedles 400 may be suspended or grounded, and the microneedles 400 have a zero potential, so that an electric field generated between the first electrode plate 200 and the second electrode plate 300 may generate a marginal effect. The present invention may heat the skin target tissue using heat surrounding the tips of the microneedles 400 to accomplish treatment. So set up, compare with current micropin therapeutic instrument, can reach the effect of treatment equally, and simplified the complex construction that traditional radio frequency power supply and micropin are connected, reduce the production degree of difficulty, reduction in production cost.
Referring to fig. 1 and fig. 5, further, the first electrode plate 200 and the second electrode plate 300 are both capacitor plates. It can be understood that two capacitor plates are connected to two ends of the rf power source, and the capacitor plate connected to the positive electrode of the rf power source is charged with positive electricity, and the capacitor plate connected to the negative electrode of the rf power source is charged with negative electricity, so that an electric field is generated between the two capacitor plates (between the first electrode plate 200 and the second electrode plate 300), and a high-heat region is formed in the microneedle 400, thereby treating the skin.
In this embodiment, the micro-needle 400 is a needle thermocouple. It should be noted that, in the existing micro-needle therapeutic apparatus, the micro-needle 400 is connected to the radio frequency power source, so that the micro-needle 400 penetrates into the skin and then performs radio frequency therapy on the deep layer of the skin. In order to monitor the temperature of the treatment area, a situation in which the skin is burned is avoided. One or more microneedles 400 that may be therein are not connected to a radio frequency power source but are directly connected to a thermocouple. However, due to the radio frequency energy generated by the neighboring micro-needles 400, certain interference can be generated on the thermocouple corresponding to the temperature measuring micro-needle 400, and the measurement accuracy is affected.
The needle type thermocouple used as the microneedle 400 can not only penetrate into the skin to release heat energy for treatment, but also can utilize the property of converting the heat energy into electric energy of the thermocouple to monitor the temperature of the microneedle 400 in real time, thereby ensuring the treatment safety. The needle type thermocouple automatically measures and monitors in real time, and when the temperature is higher than a certain value, the temperature of the human body to the microneedle 400 is not suitable, so that the treatment experience of a user is reduced. If the micro-needle 400 pierces into the human body, the thermocouple monitors the temperature, and the use safety of the micro-needle therapeutic apparatus is improved.
A needle thermocouple as the microneedle 400 may be used to measure the temperature at the treatment site. The thermocouple is used for measuring temperature, which is a simple, reliable and high-accuracy practical method widely applied at present. Because the condition that the temperature is too high can appear in micropin 400 after the micropin therapeutic instrument starts for a long time, and when micropin 400 stabs the human body, if the temperature is too high, scald very easily. Therefore, by measuring the degree of heating of the microneedles 400, the temperature can be effectively controlled. One end of the thermocouple is heated, and the measuring end of the thermocouple can sense the change of temperature, so that the heat energy of the thermocouple is converted into electric energy, a potential difference is formed in the thermocouple, namely a microneedle 400 circuit, the temperature at the tip of the microneedle 400 can be obtained through the potential difference, and when the microneedle 400 reaches a certain temperature in a human body, the circuit part makes corresponding reflection, so that the purpose of controlling the temperature is realized.
Above-mentioned treatment method, after realizing that micropin 400 punctures the skin, certain marginal effect can be produced when the electric field passes through micropin 400, and the ambient temperature at micropin 400 tip can rise, compares with current micropin therapeutic instrument, equally can reach the effect of treatment. Meanwhile, the microneedle 400 is a needle type thermocouple, so that the temperature inside the skin can be detected, the interference of radio frequency energy is reduced, the real-time temperature detection precision of the microneedle therapeutic apparatus is improved, and comfortable treatment experience is brought to a user.
Referring to fig. 8, in the present embodiment, an isolation region 420 wrapping an insulating film and the high-heat region 410 not wrapping the insulating film are formed on the surface of the microneedle 400, the insulating film is used for isolating electric field energy, at least two high-heat regions 410 are disposed on the surface of the microneedle 400, and the two adjacent high-heat regions 410 are disposed with the isolation region 420 therebetween.
It should be noted that the skin, as the largest organ of mammals, is the mechanical barrier between the body and the outside, and has a complex tissue structure and multiple physiological functions. The skin is divided into epidermis, dermis and hypodermis from outside to inside in sequence. The dermis is composed of collagen and elastin, nerves, capillaries, sweat glands and sebaceous glands, lymphatic vessels and hair roots, and the tissues are distributed at different depths under the skin.
It is understood that the isolation region 420 wrapped with the insulating film can isolate electric field energy, and the high heat region 410 not wrapped with the insulating film is directly exposed, and the high heat region 410 is formed by a marginal effect of an electric field. When a patient needs treatment, radio frequency energy is output to the first electrode plate 200 and the second electrode plate 300 through the radio frequency power supply to generate electric field energy, and the electric field energy is isolated by the insulating film. If the microneedle 400 is used as a high heat region 410 throughout the entire length thereof, a large heat diffusion region is formed, which may cause a problem that the electric field generates non-uniform heat energy in the microneedle 400. According to the technical scheme, the original high-heat area 410 is divided into more than two high-heat areas 410, the heat dispersion area generated during treatment is changed into a plurality of continuous small heat dispersion areas from the original large heat dispersion area, and the energy is more uniform. Is favorable for improving the treatment effect.
Microneedle therapy is primarily directed to the dermis layer. The high heat zone 410 is primarily disposed in the dermis layer. And the microneedles 400 penetrate too deeply to possibly damage nerves. The microneedle 400 should have a length that can extend into the dermal layer without damaging the nerve at a deeper level. Referring to fig. 8, in the present embodiment, one of the high heat regions 410 is disposed at the tip of the microneedle 400. So configured, the length of the microneedle 400 is appropriate. The microneedles 13 do not penetrate excessively deep into the skin to damage the nerves and tissues in the deep layer when the treatment is performed.
Referring to fig. 8, in the present embodiment, the insulating film is made of an electrically insulating material. It is understood that the electrically insulating material may be plastic, teflon, etc., and is not limited herein, and only the insulating film is required to isolate the electric field energy.
In this embodiment, the area of the second electrode plate 300 is larger than the area of the first electrode plate 200. Since the first electrode plate 200 is located at the end of the therapeutic apparatus body 100, the area thereof is limited by the therapeutic apparatus body 100. The second electrode plate 300 is an electrode plate movable relative to the first electrode plate 200, and the area of the second electrode plate 300 is larger than the area of the first electrode plate 200, so that the area of the first electrode plate 200 can be fully utilized, an electric field area the same as that of the first electrode plate 200 is formed, and the enlargement of the area of a treatment region is facilitated.
Referring to fig. 1 to 4, in the present embodiment, the periphery of the first electrode plate 200 is chamfered. It can be understood that, during the treatment process, the treatment surface 220 of the first electrode plate 200 is attached to the part to be treated, and the first electrode plate 200 and the part to be treated generate stress, and if the first electrode plate 200 is not chamfered and relaxed, the generated stress is more concentrated, and the user feels more pain. And the stress generated by the arranged chamfer angle is small, so that the comfort of a user is improved.
Similarly, referring to fig. 1 to 4, in the present embodiment, the first electrode plate 200 is disposed in a square shape with rounded corners. The rounded corners reduce stress generated during treatment of the first electrode plate 200.
The thinner the microneedle 400 is, the less the damage to the skin is, and meanwhile, the marginal effect of the electric field generated by the microneedle therapeutic apparatus is better, and the heat generated around the tip of the microneedle 400 is high, which is beneficial to the treatment of the microneedle 400 on the skin. In the present embodiment, the diameter of the microneedle 400 is 0.1mm to 0.5 mm.
Referring to fig. 6 to 7, in the present embodiment, the through holes 210 are arranged in an array on the first electrode plate 200, and the diameter of the through holes 210 is 0.05 to 0.5mm larger than the diameter of the microneedles 400. It can be understood that the through holes 210 are arranged on the first electrode plate 200 in an array, that is, the microneedles 400 are arranged in an array, and may be 5 rows and 6 columns or 5 rows and 5 columns, the number of the through holes 210 is equal to that of the microneedles 400, because the microneedles 400 are thin, the microneedles 400 are easy to deviate from the axis of the microneedle therapeutic apparatus when being installed, and the diameter of the through holes 210 may be larger than the diameter of the microneedles 400 by 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, and the like, which is not limited specifically herein. So set up, be favorable to guaranteeing that micropin 400 is parallel with the axis with the micropin therapeutic instrument on length direction when installing, effectively avoid the crooked condition of micropin 400.
The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the technical solutions of the present invention that are made by using the contents of the specification and the drawings or directly/indirectly applied to other related technical fields are included in the scope of the present invention.
