Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, and in particular to an array type multi-pole electrode device and an excitation method thereof. BACKGROUND

[0002] Pelvic floor dysfunction diseases, such as stress urinary incontinence, pelvic organ prolapse, vaginal relaxation, etc., are common diseases that affect women of all ages, especially postpartum and elderly women. The main cause is that the pelvic floor support structure (including muscles, fascia, ligaments, etc.) is damaged, relaxed due to factors such as childbirth, aging, and changes in hormone levels, resulting in a decrease in its support for pelvic organs.

[0003] At present, the treatment methods for pelvic floor dysfunction mainly include three categories: non-surgical treatment, surgical treatment and physical therapy. Non-surgical treatment includes pelvic floor muscle exercise (such as Kegel exercise), use of pessary, etc., but this method often takes a long time to take effect and requires the patient to adhere to it for a long time, with poor compliance. Surgical treatment is to reconstruct the support structure by implanting a sling or performing tissue repair, which has a direct effect, but as an invasive operation, it has the problems of surgical risk, postoperative complications and long recovery period.

[0004] In recent years, radiofrequency technology has been applied to this field as a non-invasive physical therapy method. However, the existing radiofrequency treatment devices are usually large in size and need to be operated by professional physicians in specific places such as hospitals, which limits the treatment process to medical resources and requires patients to frequently go back and forth, lacking convenience. In addition, the radiofrequency electrodes of the existing devices are usually of a whole structure, and the energy output mode is relatively single and static, making it difficult to simulate dynamic and orderly physiotherapy methods such as pressing and lifting in rehabilitation therapy, and the degree of treatment refinement is insufficient.

DETAILED DESCRIPTION

[0018] The following will be described in detail in combination with the accompanying drawings Figures 1-8 The application will be further described in detail. Example 1

[0019] An array type multi-pole electrode device, referring to Figures 1-8 , comprising a handheld host 1, a cable 2 and a treatment handle 3 connected with the cable 2.

[0021] The treatment handle 3 is provided with a hand-held part 31 close to one end of the cable 2, and the hand-held part 31 is fixedly connected with the cable 2. The other end of the treatment handle 3 extends in an axial direction and is provided with a cylindrical working part 32. In this embodiment, the treatment handle 3 is integrally arranged with the cylindrical working part. The outer surface of the cylindrical working part 32 is provided with a plurality of groups of radio frequency electrodes 4. The plurality of groups of radio frequency electrodes 4 are sequentially arranged from the end of the cylindrical working part 32 away from the working part to the end close to the working part. In this embodiment, the plurality of groups of radio frequency electrodes 4 are sequentially arranged as a first radio frequency electrode 42, a second radio frequency electrode 43, a third radio frequency electrode 44, a fourth radio frequency electrode 45, a fifth radio frequency electrode 46, a sixth radio frequency electrode 47, a seventh radio frequency electrode 48, and an eighth radio frequency electrode 49.

Each group of radio frequency electrodes 4 includes a plurality of electrode pieces 41 distributed in a circumferential direction of the cylindrical working part 32. In this embodiment, each group of radio frequency electrodes 4 is provided with two electrode pieces 41. The two electrode pieces 41 are both arranged in a strip shape and symmetrically arranged with respect to a center line of the cylindrical working part 32. At least part of the surface of the strip-shaped electrode piece 41 is arranged on an arc-shaped side wall surface of the cylindrical working part 32.

[0022] In this embodiment, the end of the cylindrical working part 32 away from the hand-held part 31 is further provided with a head electrode 5.

[0023] In this embodiment, the head electrode 5 is arranged in an arc surface hemispherical structure matching the curvature of the end outer wall of the cylindrical working part 32. In this embodiment, the head electrode 5 is arranged in two, and the two head electrodes 5 are symmetrically arranged with respect to the center line of the cylindrical working part 32.

[0024] The end of the cylindrical working part 32 toward the hand-held part 31 is further provided with an extension part 33. The extension part 33 includes a first extension section 331 and a second extension section 332. The first extension section 331 is connected with the cylindrical working part 32 at one end and extends in an axial direction of the cylindrical working part 32. The second extension section 332 is connected with the other end of the first extension section 331 and extends in an axial direction and expands in a radial direction to form a horn-shaped extension structure connected with the hand-held part 31. The diameter of the first extension section 331 is smaller than the diameter of the cylindrical working part 32. The first extension section 331 is sequentially sleeved with a first annular electrode 6 and a second annular electrode 7 in an axial direction. The small-diameter side of the horn-shaped extension structure is connected with the first extension section 331. The large-diameter side of the horn-shaped extension structure is connected with the hand-held part 31. The outer wall surface of the horn-shaped extension structure is provided with at least one group of profiled electrodes 8 matching the curvature thereof. In this embodiment, one group of profiled electrodes 8 is preferred, and the group is provided with two profiled electrodes 8. The two profiled electrodes 8 are symmetrically arranged with respect to the center line of the cylindrical working part 32.

[0025] When the device needs to be used, only need to put the cylindrical working part 32 and the extension part 33 into the human tissue, and then input the instruction through the handheld host 1, then the electrodes on the cylindrical working part 32 and the extension part 33 will heat in different modes according to the instruction, so as to realize the treatment of the human tissue.

[0026] Wherein, the head electrode 5, the first radio frequency electrode 42, the second radio frequency electrode 43, the third radio frequency electrode 44, the fourth radio frequency electrode 45, the fifth radio frequency electrode 46, the sixth radio frequency electrode 47, the seventh radio frequency electrode 48, the eighth radio frequency electrode 49, the first radio frequency electrode 42, the second radio frequency electrode 43, the third radio frequency electrode 44, the fourth radio frequency electrode 45, the fifth radio frequency electrode 46, the sixth radio frequency electrode 47, the seventh radio frequency electrode 48, the eighth radio frequency electrode 49, the first ring electrode 6, the second ring electrode 7 and the different electrode 8 in the embodiment can be numbered from left to right, and the control module in the handheld motor is provided with a plurality of preset electrode excitation sequence algorithms, which aims to control the twelve groups of array type radio frequency electrodes 4 on the treatment head in a programmed time sequence and spatial combination. In the single layer sequential excitation mode, the control module will activate the adjacent single electrode group in sequence according to the predetermined direction, forming a moving, superficial layer high energy focus. This mode simulates linear sliding physiotherapy method to promote microcirculation and neogenesis of surface tissue; in the double layer or multi layer sequential excitation mode, the control module will activate two or more groups of adjacent electrodes as a whole synchronously, and make the activated whole move along the axial direction of the cylindrical working part 32 in sequence, thereby constructing a dynamic energy field with wider range and deeper penetration in the tissue. This mode simulates the composite method of kneading or pressing to perform more effective thermal stimulation and collagen remodeling on deep fascia and support structure.

[0027] Compared with the static and single heating mode of the prior art, the present scheme can stimulate the pelvic floor tissue in multiple dimensions and multiple levels, which is expected to activate cell neogenesis and remodeling in a wider area, thereby enhancing the effectiveness and thoroughness of the treatment; at the same time, the user can select one of the excitation modes according to his own situation, which makes the present application adapt to different situations of different users and meet the diversified needs of different users, thereby improving the applicability of the device; at the same time, the head electrode 5, the first ring electrode 6, the second ring electrode 7 and the different electrode 8 in the embodiment increase the area of the electrode, thereby increasing the treatment area of the device, so that the user can obtain better treatment effect. Through the combination and switching of the above different excitation modes, the present scheme converts the static energy output into a dynamic, bionic and multi-level energy transmission process, ensuring that the radio frequency energy can act on the different levels of the pelvic floor tissue structure more comprehensively, uniformly and deeply, thereby achieving the purpose of significantly improving the overall treatment effect.

[0028] Further, the end of the cylindrical working part 32 away from the handle part 31 is a round head in the embodiment, the cylindrical working part 32 is actually a circular truncated cone, the diameter gradually decreases from the direction away from the handle part 31 to the direction close to the handle part 31, and the second extension section 332 is connected with the other end of the first extension section 331 and extends along the axial direction and expands radially to form a horn-shaped extension structure connected with the handle part 31, the diameter of the first extension section 331 is smaller than the diameter of the cylindrical working part 32, that is, the diameter of the entire working part from left to right in the embodiment is first gradually reduced and then suddenly increased, which is relatively ergonomic and greatly improves the comfort of the user.

[0029] Meanwhile, the electrode pieces 41 in the embodiment are all bent into a semi-ring shape matching the curved surface of the cylindrical working part 32, and then the semi-ring-shaped electrode pieces 41 are attached to the peripheral wall of the cylindrical working part, so that the electrode pieces 41 can be installed on the peripheral wall of the cylindrical working part 32 as relatively smooth as possible; similarly, the head electrode 5, the first ring-shaped electrode 6, the second ring-shaped electrode 7 and the special-shaped electrode 8 in the embodiment are all attached to the surface of the cylindrical working part 32 as relatively smooth as possible, so that the surface of the cylindrical working part 32 is smooth as a whole, thereby avoiding the discomfort caused by the cylindrical working part 32 when it is put into the human body as much as possible, and the electrode area can be increased by arranging the head electrode 5, the ring-shaped electrodes (including the first ring-shaped electrode 6 and the second ring-shaped electrode 7) and the special-shaped electrode 8, which is beneficial to further improve the treatment effect.

[0030] The cylindrical working part 32 and the treatment handle 3 are hollow in the embodiment, the inside of the cylindrical working part 32 is provided with a plurality of temperature sensors 10 and a plurality of groups of PCB circuit boards 101 extending along the axial direction of the cylindrical working part 32, two PCB circuit boards 101 are provided in the embodiment, and the two PCB circuit boards 101 are also mirror-imaged, the plurality of temperature sensors 10 in the embodiment correspond to the plurality of electrode pieces 41 one by one, the electrode piece 41 at the upper end is in electrical contact with the PCB circuit board 101 at the upper end, the electrode piece 41 at the lower end is in electrical contact with the PCB circuit board 101 at the lower end, the temperature sensor 10 is located between the electrode piece 41 and the PCB circuit board 101, and the temperature sensor 10 is electrically connected with the PCB circuit board 101, the temperature sensor 10 is used for monitoring the temperature of the area where the corresponding electrode piece 41 is located, six wire cores are arranged in each PCB circuit board 101, and 12 wire cores are arranged in the two PCB circuit boards 101, the ends of the 12 wire cores away from the PCB circuit boards 101 are electrically connected with the circuit board in the host through the cable 2, so as to realize the closure of the circuit.

[0031] The electrode sheet 41 is mounted on the surface of the cylindrical working part 32, and both ends of the electrode sheet 41 pass through the cylindrical working part 32 and extend into the interior of the cylindrical working part 32, and the part of the electrode sheet 41 extending into the interior of the cylindrical working part 32 is in electrical contact with the PCB circuit board 101, wherein the electrode sheet 41 is in electrical contact with the PCB circuit board 101 through a pin, and the user can control the head electrode 5, the multiple groups of radio frequency electrodes 4, the first annular electrode 6, the second annular electrode 7 and the special-shaped electrode 8 to be sequentially excited, grouped excited or all excited by the excitation sequence set by the handheld host 1, so as to simulate the operation of a human hand.

[0032] The handheld host 1, the cable 2 and the treatment handle 3 are in a split structure in the embodiment, and the volume and weight of the device are smaller than those of the traditional device, so the device has excellent convenience, the user does not need to go back and forth between professional medical places, but can complete the treatment in a private and convenient environment such as at home according to instructions, and therefore, the scheme fundamentally breaks the dependence of the traditional radio frequency treatment on specific places and professional personnel, greatly improves the convenience of treatment, and protects the privacy of the user.

[0033] The multiple temperature sensors 10 in the embodiment correspond to the multiple electrode sheets 41 one by one, and the temperature sensor 10 is located between the electrode sheet 41 and the PCB circuit board 101 and is in electrical contact with the PCB circuit board 101 through a pin.

[0034] Each electrode sheet 41 is located in an area provided with an independent temperature sensor 10, the temperature sensor 10 can monitor the real-time temperature of the area where the corresponding electrode sheet 41 is located in real time, and transmit the temperature data to the handheld host 1. The core of radio frequency treatment is thermal effect, and high temperature can cause tissue scalding. By arranging multiple temperature sensors 10 corresponding to the electrode sheet 41, distributed and accurate temperature monitoring of the treatment area can be realized. Once the temperature of any local area exceeds the safety threshold, the control module in the handheld host 1 can quickly adjust or stop the energy output of the area, thereby fundamentally avoiding the risk of scalding. The arrangement of the temperature sensor 10 greatly improves the safety of the radio frequency treatment process. In addition, radio frequency treatment needs to be carried out within a specific temperature range to achieve the best effect, and distributed temperature monitoring ensures that the temperature of the entire treatment area can be maintained within the effective range, avoiding local overheating or under-temperature, thereby ensuring the effect of each treatment.

[0035] Referring to Figure 4 , Figure 5 and Figure 6 , the cylindrical working part 32 in the embodiment is further provided with a negative pressure adsorption assembly 9, and the negative pressure adsorption assembly 9 in the embodiment includes a connecting pipe 91 and a micro vacuum pump.

[0036] The cylindrical working part 32 in the embodiment is provided with eight groups of negative pressure holes 34, the cross section of the negative pressure hole 34 is circular, the eight groups of negative pressure holes 34 correspond to the first to eighth radio frequency electrodes 49 one by one, each group of negative pressure holes 34 includes two negative pressure holes 34, the two negative pressure holes 34 are also mirror image arranged, the two negative pressure holes 34 in each group are coaxially arranged, and the connecting axis of the two negative pressure holes 34 is perpendicular to the vertical connecting line of the two electrode sheets 41 on the corresponding radio frequency electrode 4, the connecting pipe 91 is arranged along the length direction of the cylindrical working part 32, and the connecting pipe 91 is arranged between the two PCB circuit boards 101, a micro vacuum pump (not shown in the figure) is arranged in the handheld host 1, one end of the connecting pipe 91 extends to the inside of the handheld part 31, then passes out from the end of the handle away from the treatment handle 3, then passes through the cable 2, and is inserted into the inside of the handheld host 1 and communicates with the micro vacuum pump, a plurality of branch pipes 92 are communicated on the peripheral wall of the connecting pipe 91, the plurality of branch pipes 92 correspond to the plurality of negative pressure holes 34 one by one, the branch pipe 92 is coaxially arranged with the corresponding negative pressure hole 34, the end of the branch pipe 92 away from the connecting pipe 91 communicates with the negative pressure hole 34, and a gas-permeable membrane allowing gas to pass through but not allowing liquid to pass through is also arranged at the negative pressure hole 34.

[0037] When the user places the cylindrical working part 32 and the extension part 33 into the human tissue and adjusts the position, the micro vacuum pump is started, the micro vacuum pump draws out the gas in the gap between the motor surface and the human tissue surface through the connecting pipe 91 and the branch pipe 92, then the gap is in a negative pressure state, the human tissue can adsorb the surface of the electrode, so that the surface of the human tissue and the electrode are better attached, which not only enables the energy on the electrode to be better transmitted into the human tissue, but also fixes the cylindrical working part 32 and the extension part 33 at a specific position in the human tissue, avoiding the deviation of the best position of the cylindrical working part 32 and the extension part 33 in the human tissue due to the shaking of the human body, and causing the treatment effect to be reduced.

[0038] The handheld host 1 in the embodiment is also provided with a current sensor for detecting the current value in the power supply circuit of the micro vacuum pump, and the current sensor (not shown in the figure) is electrically connected with the control module.

[0039] The load of the micro vacuum pump is closely related to its working current. When the cylindrical working part 32 and the extension part 33 successfully adsorb the tissue, the pipeline is sealed, and the micro vacuum pump needs to continue to pump out air in a low-pressure environment. At this time, the load of the micro vacuum pump is the largest, and its working current will reach a relatively high stable value. When adsorption fails and the pipeline leaks, external air will continuously flow in. For the pump, it is only pumping an environment close to normal pressure. At this time, the load of the pump is the smallest, and its working current will significantly decrease to a lower value. Therefore, a high preset value can be set in the control module. When the current of the current sensor is about to reach this high preset value, it indicates that the cylindrical working part 32 and the extension part 33 have not successfully adsorbed the tissue or the pipeline is leaking. The electrode will not start, and the user can adjust the position of the cylindrical working part 32 and the extension part 33. After the display shows successful adsorption, the electrode will start. If multiple times of unsuccessful adsorption are found, it indicates that the pipeline leaks and needs to be repaired.

[0050] By combining different groups and sequences, a variety of treatment plans can be derived. This allows for highly customized treatment plans based on the user's specific symptoms, stage, and feedback, greatly improving the flexibility and targeted nature of treatment. Furthermore, compared to the energy dispersion caused by simultaneous stimulation of all electrodes, sequential and regional energy concentration can achieve higher energy density in specific areas while ensuring the total power does not exceed limits, thus achieving deeper therapeutic effects. Simultaneously, sequential stimulation also provides the body's tissues with a work-rest rhythm, which is more in line with physiological laws.

[0051] In addition, stimulating adjacent electrodes as a whole can create a larger continuous area of ​​action than a single electrode. This is very effective when it is necessary to lift or heat a large area of ​​tissue as a whole, and can cover the entire treatment area in a shorter time, thus improving treatment efficiency. Moreover, this grouping method simulates a therapist's use of the palm or multiple fingers to perform surface massage rather than point massage, which can produce synergistic effects on a larger range of muscle groups and tissue structures, making it suitable for treatment stages that require overall rehabilitation.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
