Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to a care device for skin folds. Background Technology

[0002] In the field of skin wrinkle treatment equipment, laser, radiofrequency, and ultrasound technologies are the mainstream methods. Among them, radiofrequency technology has become a widely used clinical approach due to its definite treatment effect and relatively few side effects. Radiofrequency treatment devices transmit radiofrequency energy to the skin tissue through electrodes on the handpiece, causing a thermal effect in the subcutaneous tissue, which in turn stimulates collagen contraction and regeneration, thereby improving wrinkles.

[0003] In existing technologies, the handpiece electrodes of radiofrequency ablation devices generally adopt a fixed mode, meaning the relative position of the electrodes within the handpiece remains unchanged. The operator applies radiofrequency energy to the target area by manually sliding the handpiece across the skin surface. However, this fixed electrode mode has significant shortcomings in practical applications: First, fixed electrodes cannot actively open skin folds. In clinical treatment, the operator usually needs to use their other hand to open the skin folds before applying the radiofrequency electrode. This operation is highly dependent on the operator's experience and technique, increasing the difficulty of operation and making it difficult to ensure consistency between different operators and between multiple operations by the same operator, affecting the stability of the treatment effect. Second, fixed electrodes are prone to creating non-contact points on non-planar skin surfaces, leading to electric shock. The skin surface in treatment areas such as the face is not an ideal plane but rather an uneven, curved surface following the bone structure. When a fixed and rigid electrode contacts such a surface, it is difficult to achieve complete adhesion to the skin, easily creating micro-gaps in local areas. When radio frequency energy is output, instantaneous discharge is likely to occur at this gap, resulting in electric shock, which brings obvious discomfort to consumers, and in severe cases, there is even a risk of burns and scarring.

[0004] Therefore, it is necessary to provide a new care device for skin folds to solve the aforementioned problems existing in the prior art. Summary of the Invention

[0005] The technical problem to be solved by this application is how to provide a skin care device that can adapt to the skin position and provide care for skin folds.

[0006] To solve the above-mentioned technical problems, according to an embodiment of this application, a care device for skin folds is provided, comprising: a grip portion, which is hollow and has a transmission end and a treatment end; a conduction module disposed within the grip portion, and one end of the conduction module being electrically connected to the device via the transmission end; a transmission module disposed within the grip portion, and one end of the transmission module extending to the outside of the treatment end to form a connection end, and the other end being electrically connected to the conduction module; at least two movable electrode ends, each disposed at the connection end, with a gap between adjacent movable electrode ends, and each movable electrode end having a contact surface for contacting the skin; the movable electrode ends contact the skin and rotate, while at least two movable electrode ends move in a direction away from each other, so that the contact surfaces adhere to the skin and then move in a direction away from each other to smooth out the folds on the skin.

[0007] According to an embodiment of this application, the centroid of the connecting end is spaced from the centroid of the movable electrode tip, so that the movable electrode tip rotates after the contact surface contacts the skin.

[0008] According to an embodiment of this application, the transmission module includes a plurality of metal springs, the number of which corresponds to the movable electrode tip; one end of each metal spring is electrically connected to the conduction module, and the other end extends to the outside of the treatment end to form the connection end; the movable electrode tip is fixedly disposed at the connection end.

[0009] According to an embodiment of this application, the inner wall of the gripping part is provided with a snap-fit ​​groove; the side wall of the metal spring is provided with a snap-fit ​​protrusion, and the snap-fit ​​protrusion snaps into the snap-fit ​​groove; at least some of the adjacent metal springs move away from each other from the snap-fit ​​protrusion toward the treatment end, and the movable electrode tip drives the metal spring to undergo elastic deformation to decompose the displacement of the movable electrode tip into axial and radial displacements along the gripping part.

[0010] According to an embodiment of this application, the gripping part includes a first segment and a second segment; the first segment is detachably connected to the second segment; a portion of the conduction module is disposed in the first segment, and the remaining portion of the conduction module is disposed in the second segment, and the transmission module is disposed in the second segment.

[0011] According to an embodiment of this application, the conduction module includes a first circuit board and a second circuit board; the first circuit board is disposed in the first segment, and one end of the first circuit board is electrically connected to the device via the transmission end, and the other end is provided with a pin; the second circuit board is disposed in the second segment, and one end of the second circuit board is electrically connected to the transmission module, and the other end is provided with a slot; after the first segment and the second segment are connected, the pin passes through the slot to electrically connect the first circuit board and the second circuit board.

[0012] According to an embodiment of this application, there is an installation gap between the first circuit board and the second circuit board, and a connection module is provided within the installation gap; a control groove is provided on the first segment, and a connection groove is provided on the second segment; the connection module includes a connector disposed opposite to each other and an elastic member disposed between the oppositely disposed connectors; one end of the connector is disposed in the control groove, and the other end has a protruding structure; the elastic member is used to push the oppositely disposed connectors away from each other so that after the first segment and the second segment are connected, the protruding structure engages with the connection groove, so that the protruding structure of the connector engages with the connection groove, thereby achieving the connection and fixation of the first segment and the second segment. At the same time, when the connector is squeezed at the control groove position, the elastic member is compressed, and the two connectors move closer to each other, so that the protruding structure of the connector disengages from the connection groove, thereby achieving the disassembly of the first segment and the second segment, facilitating the replacement of the second segment, and preventing cross-infection during use by different users.

[0013] According to an embodiment of this application, the transmission module includes multiple sets of transmission parts, each set of transmission parts corresponding to one movable electrode tip; each set of transmission parts includes a first transmission rod and at least two second transmission rods; one end of the first transmission rod abuts against the conduction module, and the other end extends to the outside of the treatment end to form the connection end; the movable electrode tip is rotatably disposed at the connection end; one end of the second transmission rod is rotatably disposed within the grip portion, and the other end is rotatably disposed on the first transmission rod, so that the first transmission rod can move axially and radially along the grip portion.

[0014] According to an embodiment of this application, the transmission module includes a first limiting member, a second limiting member, a transmission member, and a reset member; the first limiting member is disposed within the gripping portion and has multiple limiting holes, each limiting hole corresponding to one of the transmission portions; the transmission member is movably disposed within the limiting holes, and the end of the transmission member is provided with a transmission end; one end of the reset member abuts against the first limiting member, and the other end abuts against the transmission end so that the transmission end abuts against the first transmission rod, thereby electrically connecting the movable electrode tip to the transmission member; the second limiting member is disposed at the other end of the transmission member for limiting, and the other end of the transmission member is electrically connected to the device.

[0015] According to an embodiment of this application, the sidewall of the connecting end is flush with the sidewall of the movable electrode tip near the axis of the gripping part, and the contact surface has an initial angle with the horizontal plane, the initial angle being greater than 0° and less than 90°.

[0016] By employing the above technical solution, at least two movable electrode tips are used. These movable electrode tips can rotate after contacting the skin and simultaneously move away from each other, allowing the contact surface to flatten skin folds while adhering to the skin. Therefore, the electrodes can simultaneously complete the wrinkle-flattening action during treatment, eliminating the need for additional manual intervention by the operator, reducing reliance on operator experience, and improving treatment consistency and convenience. By creating a gap between the centroid of the connecting end and the centroid of the movable electrode tip, the reaction force from the skin after contact generates a torque that causes the movable electrode tip to rotate, allowing the contact surface to adaptively adjust its angle to fit the skin surface as closely as possible. Combined with the movement of the movable electrode tips away from each other, it can adapt to skin surfaces with different curvatures, reducing or even eliminating non-contact points between the electrode and the skin, effectively avoiding radiofrequency shock, and improving treatment safety and comfort. In the embodiment using metal springs as the transmission module, the metal springs are fixed by the engagement of the snap-fit ​​protrusion and the snap-fit ​​groove, and adjacent metal springs are moved away from each other from the snap-fit ​​protrusion toward the treatment end. This decomposes the skin reaction force on the movable electrode tip into axial and radial displacements along the grip. This not only enables the adaptive rotation of the movable electrode tip but also allows it to generate controllable radial displacement to open up skin folds. Simultaneously, the axial displacement provides a buffer space for the electrode to adapt to different skin heights, improving the device's adaptability to skin surface morphology. In the embodiment using transmission rods as the transmission module, a linkage mechanism consisting of a first transmission rod and at least two second transmission rods allows the first transmission rod to move axially and radially along the grip, thereby driving the movable electrode tip to achieve a combined rotational and retracting motion. The second transmission rods effectively limit the first transmission rod, ensuring the stability and reliability of the movable electrode tip during movement. By aligning the sidewall of the connecting end with the sidewall of the movable electrode tip near the axis of the grip, and establishing an initial angle greater than 0° between the contact surface and the horizontal plane, the movable electrode tip is in an easily rotating initial position even before contacting the skin. Once in contact with the skin, the movable electrode tip rotates more easily due to the skin's reaction force and the electrode tip's own weight, increasing the contact area and further enhancing the electrode's adaptive fit to the skin's curvature.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art. The terms "comprising" and similar expressions used herein mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, but does not exclude other elements or objects.

[0026] The following is in conjunction with the appendix Figures 1-7 The specific embodiments of the present invention will be further described in detail below.

[0027] Embodiments of the present invention provide a care device for skin folds, which is used to improve skin folds or wrinkles, and is particularly suitable for care of skin folds or wrinkles on non-smooth surfaces. Existing care devices use a fixed mode for radio frequency electrodes. For different locations on the skin, especially those with folds, the fixed motor cannot effectively open the skin for care. The operator needs to use their hands to open the skin folds before using the radio frequency electrodes for treatment. Specifically, the care device includes a grip 100, a conduction module 200, a transmission module, and at least two movable electrode ends 400.

[0028] In some specific embodiments, the care device of this application is particularly suitable for the care of the skin around the eyes. It can open up the folds around the eyes for care through the movable electrode end 400. At the same time, it can adapt to the uneven eye structure caused by the bones around the eyes. With the cooperation of the device and electrodes, it can also perform care methods such as removing dark circles and eye bags.

[0029] In some embodiments, the gripping part 100 is hollow and has a transmission end 101 and a treatment end 102. Specifically, the gripping part 100 is rod-shaped, and its cross-sectional shape can be circular, elliptical, or other shapes. In this embodiment, an elliptical cross-sectional shape is preferred to facilitate gripping. The gripping part 100 has two ends, namely the transmission end 101 and the treatment end 102. The transmission end 101 is used for transmitting electrical signals, and the treatment end 102 is used to set the movable electrode tip 400 to facilitate skin care. The specific configuration will be described later.

[0030] In some embodiments, the conduction module 200 is disposed within the grip portion 100, and one end of the conduction module 200 is electrically connected to the device via the transmission end 101. Specifically, the conduction module 200 is made of metal, such as copper, iron, or other conductive materials. No specific limitation is imposed here, and the appropriate material is selected according to the usage requirements during actual use. The conduction module 200 is used for conducting electricity, and one end of the conduction module 200 is provided with a wire. The wire passes through the transmission end 101 and extends to the device, where it is electrically connected. The device can be a central control device or a nursing device. No specific limitation is imposed here, but the main purpose is to provide power and transmit current through the conduction module 200 to the movable electrode end 400 for nursing treatment of skin folds. At the same time, the device can adjust the current magnitude, which is known to those skilled in the art and will not be described in detail here.

[0031] In some embodiments, the transmission module is located within the gripping part 100, and one end of the transmission module extends to the outside of the treatment end 102 to form a connection end 301, while the other end is electrically connected to the conduction module 200. Specifically, each component in the transmission module extends to the outside of the treatment end 102 to form a corresponding connection end 301. The number of connection ends 301 corresponds to the number of movable electrode ends 400, and each connection end 301 corresponds to one movable electrode end 400. More specifically, the connection end 301 is used to connect with the movable electrode end 400, which can be a fixed connection or a rotatable connection, as will be described later. At the same time, the transmission module is also made of metal so that the current can be transmitted to the movable electrode end 400 after passing through the conduction module 200 and the transmission module in sequence.

[0032] In some embodiments, at least two movable electrode ends 400 are provided, which may be two, three or more. When two movable electrode ends 400 are provided, they are arranged opposite to each other; when three or more movable electrode ends 400 are provided, they are arranged circumferentially. In this embodiment, two movable electrode ends 400 are selected, and the description will focus on two movable electrode ends 400. Both movable electrode ends 400 are located at the connection end 301. Specifically, each movable electrode end 400 corresponds to a part of the connection end 301, and there is a gap between adjacent movable electrode ends 400 to facilitate the movement of the movable electrode ends 400. The movable electrode end 400 has a contact surface 401 for contacting the skin. The contact surface 401 is the end face of the movable electrode end 400 away from the grip portion 100. Specifically, the movable electrode end 400 is a radio frequency electrode, and its contact surface 401 contacts the skin to provide skin care or treatment. During care or treatment, the movable electrode tip 400 contacts and rotates with the skin. Simultaneously, at least two movable electrode tips 400 move away from each other, causing the contact surface 401 to adhere to the skin and then move away from each other to smooth out skin folds. Specifically, the contact surface 401 of the movable electrode tip 400 contacts the skin. Since the skin is not flat but has a curved surface, the movable electrode tip 400 rotates after contacting the skin, allowing the contact surface 401 to contact the skin as much as possible. At the same time, because there are folds on the skin, after the contact surface 401 adheres to the skin, the two movable electrode tips 400 move away from each other, thereby causing the skin at the folds to open and smooth out the folds. This facilitates care or treatment of the skin in the folds without requiring the operator to manually open them.

[0033] In some embodiments, the centroid of the connecting end 301 (the geometric center of the cross-sectional shape of the connecting end 301) is spaced from the centroid of the movable electrode 400, so that the movable electrode 400 rotates after the contact surface 401 contacts the skin. Specifically, since the centroid of the connecting end 301 is spaced from the centroid of the movable electrode 400, the movable electrode 400 will not be unable to rotate due to the reaction force from the skin perpendicular to the contact surface 401 after the contact surface 401 contacts the skin. Therefore, the movable electrode 400 rotates after the contact surface 401 contacts the skin, thereby facilitating the contact surface 401 to fit the skin as closely as possible.

[0034] In some embodiments, the transmission module includes multiple metal springs 310, the number of which corresponds to the number of movable electrode ends 400. One end of each metal spring 310 is electrically connected to the conduction module 200, and the other end extends to the outside of the treatment end 102 to form a connection end 301. The movable electrode ends 400 are fixedly disposed at the connection end 301. Specifically, the thickness of the metal springs 310 is between 0.5mm and 3mm, and can be 1mm or 2mm. The specific thickness is not limited here and can be set according to the usage requirements in actual use. One metal spring 310 corresponds to one movable electrode end 400. In this embodiment, two metal springs 310 are provided, each of which extends to the outside of the treatment end 102 to form a connection end 301. Since the metal springs 310 are made of metal, the current provided by the device can be conducted to the movable electrode head 400 through the metal springs 310. In addition, the movable electrode head 400 is fixedly disposed at the connection end 301, that is, the movable electrode head 400 is fixedly disposed at the part of the metal springs 310 extending outside the treatment end 102. The setting method can be welding or bolt fixing, etc. In this embodiment, the two are preferably connected by bolt fixing.

[0035] In some embodiments, to facilitate the fixing of the metal spring 310, the inner wall of the gripping part 100 is provided with a snap-fit ​​groove 103; the side wall of the metal spring 310 is provided with a snap-fit ​​protrusion 311, which snaps into the snap-fit ​​groove 103; specifically, the inner wall of the gripping part 100 is provided with two protrusions by integral molding, the two protrusions are arranged opposite each other, and each protrusion is provided with a snap-fit ​​groove 103. The width of the snap-fit ​​groove 103 is the same as the thickness of the metal spring 310. In this embodiment, each snap-fit ​​protrusion 311 is provided with two The snap-fit ​​groove 103 is used to snap the two metal springs 310 into place. Both sidewalls of the metal springs 310 are provided with snap-fit ​​protrusions 311 by integral molding. The snap-fit ​​protrusions 311 pass through the snap-fit ​​groove 103 and snap into the snap-fit ​​groove 103. More specifically, the two snap-fit ​​protrusions 311 on each metal spring 310 snap into the two snap-fit ​​grooves 103 on the oppositely arranged protrusions, thereby fixing the metal springs 310. At the same time, there is a gap between the two metal springs 310 so that the transmission of current will not be interfered with.

[0036] In some specific embodiments, at least some adjacent metal springs 310 are moved away from each other from the snap-fit ​​protrusion 311 toward the treatment end 102. The movable electrode tip 400 causes the metal springs 310 to undergo elastic deformation to decompose the displacement of the movable electrode tip 400 into axial and radial displacements along the gripping portion 100. Specifically, in this embodiment, each metal spring 310 is partially inclined. Since the metal spring 310 is fixed to the protrusion by the snap-fit ​​protrusion 311, the protrusion divides the metal spring 310 into three parts. Here, the part between one end of the protrusion and the treatment end 102 is defined as the first part, the part between the other end of the protrusion and the transmission end 101 is defined as the second part, and the part corresponding to the protrusion is defined as the third part. Among them, the metal spring 310 corresponding to the first part can be completely inclined or partially inclined. In this embodiment, the metal spring 310 is partially inclined. Furthermore, the two metal springs 310 extend away from each other from the snap-fit ​​protrusion 311 toward the treatment end 102, and then extend to the treatment end 102 in a direction parallel to the axis of the grip portion 100. The inclined portion of each metal spring 310 causes the two metal springs 310 to tend to move away from each other, so that the two metal springs 310 will not come close to each other when force is applied. At the same time, the portion of the metal spring 310 extending to the treatment end 102 is parallel to the axis of the grip portion 100, so as to facilitate fixation with the movable electrode end head 400. More specifically, after the metal spring 310 extends to the treatment end 102, it extends in a direction perpendicular to the axis of the grip portion 100 to form a planar structure that facilitates fixation of the movable electrode end head 400. The movable electrode end head 400 is fixed to this planar structure by means of bolts. In addition, after the two metal springs 310 extend to the treatment end 102, they extend in a direction perpendicular to the axis of the grip portion 100 in a direction that comes close to each other. More specifically, the end face of the movable electrode tip 400 away from the contact surface 401 is provided with a connecting block. The connecting block is connected to the connecting end 301 formed by the metal spring 310, so that there is a gap between the movable electrode tip 400 and the treatment end 102, so as to facilitate the rotation process of the movable electrode tip 400. After the movable electrode tip 400 contacts the skin, since the thickness of the metal spring 310 is 0.5mm-3mm, it can tilt under the reaction force of the skin, that is, rotate relative to the skin. At the same time, since the metal spring 310 corresponding to the first part is tilted, the reaction force of the skin on the movable electrode tip 400 will cause the metal spring 310 to undergo elastic deformation, thereby decomposing the reaction force of the skin on the movable electrode tip 400 into an axial force parallel to the grip portion 100 and a radial outward force along the grip portion 100. This makes it easier for the movable electrode tip 400 to open up the skin at the folds, and can adapt to the skin at different positions and heights.The metal spring 310 corresponding to the second part can extend towards the transmission end 101 in a direction parallel to the axis of the gripping part 100, or be inclined, or be inclined first and then extend towards the transmission end 101 in a direction parallel to the axis of the gripping part 100. The specifics are not limited here, as long as the current can be transmitted.

[0037] In some embodiments, since the movable electrode tip 400 will come into contact with the skin of different users, when a transmission module composed of metal spring 310 is provided, the grip portion 100 is set to a detachable state for the movable electrode tip 400, so that the movable electrode tip 400 can be replaced as a consumable. Specifically, the grip portion 100 includes a first section 110 and a second section 120. The first section 110 is detachably connected to the second section 120. The detachable connection method can be a threaded connection, a plug-in connection, or other detachable connection methods. In this embodiment, the two are connected by a plug-in connection. The specific structure will be described later. A portion of the conduction module 200 is located within the first section 110, while the remaining portion of the conduction module 200 is located within the second section 120. The transmission module is located within the second section 120. When the first section 110 and the second section 120 are connected, the portion of the conduction module 200 located within the first section 110 is connected to the portion of the conduction module 200 located within the second section 120, thereby enabling the conduction module 200 to transmit current.

[0038] In some embodiments, in order for the conduction module 200 to transmit current after the first segment 110 and the second segment 120 are connected, the conduction module 200 includes a first circuit board 210 and a second circuit board 220. The first circuit board 210 is disposed within the first segment 110, and its placement method can be adhesive, snap-fit, or bolted, etc., without specific limitations, as long as the position of the first circuit board 210 within the first segment 110 does not change. One end of the first circuit board 210 has a wire, which is electrically connected to the device via the transmission end 101, and the other end has a pin 211 to facilitate... The connection between the first circuit board 210 and the second circuit board 220: The second circuit board 220 is located inside the second section 120. Its setting method can be adhesive, snap-fit ​​or bolt fixation, etc., which is not limited here. The main point is that the position of the second circuit board 220 inside the second section 120 will not change. One end of the second circuit board 220 is electrically connected to the transmission module, and the other end is provided with a slot 221. After the first section 110 and the second section 120 are connected, the pin 211 passes through the slot 221 to make the first circuit board 210 and the second circuit board 220 electrically connected, so that the conduction module 200 can conduct current.

[0039] In some embodiments, to ensure stability after the first segment 110 and the second segment 120 are connected, an installation gap is provided between the first circuit board 210 and the second circuit board 220. That is, after the first segment 110 and the second segment 120 are connected, there is still an installation gap between the first circuit board 210 and the second circuit board 220. The pin 211 extends within the installation gap and connects to the slot 221. A connection module 500 is provided within the installation gap. The connection module 500 is used to fix the positions of the first segment 110 and the second segment 120. A control groove 111 is provided on the first segment 110, and a connection groove 121 is provided on the second segment 120. Specifically, the control groove 111 passes through the first segment 110 radially along the gripping part 100, so that there are two control grooves 111 oppositely arranged on the side wall of the first segment 110. Similarly, the connection groove 121 passes through the second segment 120 radially along the gripping part 100, so that there are two connection grooves 121 oppositely arranged on the side wall of the second segment 120.The connection module 500 includes connectors 510 disposed opposite each other and elastic members 520 disposed between the oppositely disposed connectors 510. The connectors 510 can be disposed on the first circuit board 210 or on the first section 110. In this embodiment, the connectors 510 are directly disposed within the oppositely disposed control slots 111. Specifically, the cross-sectional shape of a portion of the connector 510 is the same as the shape of the control slot 111, and the connector 510 passes through the control slot 111. Each control slot 111 contains one connector 510, meaning one end of the connector 510 is disposed within the control slot 111. Two connectors 510... Connecting protrusions are integrally formed on the opposing surfaces of the 0-section connectors 510. The elastic element 520 is a spring, with one end fitted onto one of the connecting protrusions and the other end fitted onto the other, thus engaging the elastic element 520 between the opposing connecting elements 510. Under the elastic force of the elastic element 520, the opposing connecting elements 510 move away from each other. The other end of the connecting element 510 has a protruding structure 511, which is L-shaped. It first extends towards the second section 120 and then extends radially outward along the gripping section 100. The radially outwardly extending portion of section 0 forms a snap-fit ​​portion, and a guide surface is provided on the end face of the snap-fit ​​portion facing the second section 120 to facilitate the movement of the second section 120. The elastic member 520 is used to push the oppositely arranged connecting members 510 away from each other so that after the first section 110 and the second section 120 are connected, the protruding structure 511 snaps into the connecting groove 121. Specifically, the second section 120 passes through the first section 110. At this time, the bottom of the second section 120 abuts against the guide surface, and under the limiting action of the guide surface, it drives the oppositely arranged connecting members 510 to move towards each other until the snap-fit ​​portion abuts against the inner part of the second section 120. The second segment 120 continues to move towards the first segment 110 until the engaging portion passes through the connecting groove 121. At this time, under the action of the elastic member 520, the oppositely arranged connecting members 510 move away from each other, and the engaging portion engages with the connecting groove 121, thereby fixing the positions of the first segment 110 and the second segment 120. During the separation of the first segment 110 and the second segment 120, the oppositely arranged connecting members 510 are pressed by hand, causing them to move closer to each other, thereby separating the engaging portion from the connecting groove 121, so as to facilitate the separation of the first segment 110 and the second segment 120. In some more specific embodiments, the first segment 110 is provided with a receiving member, which has a receiving groove. The receiving member extends from one of the control grooves 111 to the other control groove 111, so that the receiving groove communicates with both control grooves 111. The receiving groove is used to receive the connecting member 510 and the elastic member 520, thereby facilitating the control of the movement path of the connecting member 510.

[0040] In some other embodiments, the transmission module may also include other transmission methods. For example, the transmission module may include multiple sets of transmission parts 320, each set of transmission parts 320 corresponding to a movable electrode head 400; each set of transmission parts 320 includes a first transmission rod 321 and at least two second transmission rods 322; the first transmission rod 321 is disposed inside the gripping part 100 and extends along the axial direction of the gripping part 100, and one end of the first transmission rod 321 abuts against the conduction module 200, and the other end extends to the outside of the treatment end 102 to form a connection end 301, the movable electrode head 400 is rotatably disposed at the connection end 301, the first transmission rod 321 is made of metal, so the first transmission rod 321 can transmit current to the movable electrode head; one end of the second transmission rod 322 is rotatably disposed inside the gripping part 100, and the other end is rotatably disposed on the first transmission rod 321, so that the first transmission rod 321 can move along the axial and radial directions of the gripping part 100, specifically... Two, three or more second transmission rods 322 can be provided. In this embodiment, two second transmission rods 322 are provided in each group of transmission parts 320. The two second transmission rods 322 are arranged side by side along the axial direction of the grip and are parallel to each other. In addition, the grip part 100 is provided with a rotating shaft corresponding to the second transmission rod 322. One end of the second transmission rod 322 is provided with a hole and is sleeved on the rotating shaft, so that one end of the second transmission rod 322 is rotatably provided in the grip part 100, and the other end of the second transmission rod 322 is rotatably provided on the side wall of the first transmission rod 321. The two second transmission rods 322 limit the first transmission rod 321, so that the first transmission rod 321 has a tendency to move radially along the grip part 100. This makes it easier for the movable electrode end head 400 to move radially along the grip part 100 synchronously with the first transmission rod 321 after being rotated under force, so as to open up the skin folds.

[0041] In some embodiments, the movable electrode tip 400, in addition to being able to move radially along the grip portion 100, also needs to have space to move axially along the grip portion 100 to adapt to skin positions at different heights; the conduction module 200 includes a first limiting member 230, a second limiting member 240, a conduction member 250, and a reset member 260; wherein, the first limiting member 230 is disposed within the grip portion 100, and its setting method can be adhesive, snap-fit, or bolted, etc., which is not limited here, as long as the position of the first limiting member 230 within the grip portion 100 is not... The main change is that the first limiting member 230 has multiple limiting holes 231, which pass through the first limiting member 230 along the axial direction of the gripping part 100. Each limiting hole 231 corresponds to a transmission part 320. The conductor 250 is movably disposed in the limiting hole 231, and the end of the conductor 250 is provided with a transmission end 251. Both the conductor 250 and the transmission end 251 are made of metal, and the first transmission rod 321 abuts against the transmission end 251 so that the current can pass through the conductor 250, the transmission end 251 and the first transmission part 320 in sequence. Rod 321; Reset member 260 is a spring, and the reset member 260 is sleeved on the conductor 250. One end of the reset member 260 abuts against the first limiting member 230, and the other end abuts against the conductor end 251 so that the conductor end 251 abuts against the first transmission rod 321, so that the movable electrode end 400 is electrically connected to the conductor 250. The reset member 260 can apply a force away from the first limiting member 230 to the conductor end 251, so that the conductor end 251 abuts against the first transmission rod 321. At the same time, when the movable electrode end 400 is subjected to force, the reset member 260 is compressed, so that the movable electrode end 400... The electrode tip 400 can have a movement space along the axial direction of the grip portion 100; the second limiting member 240 is provided at the other end of the conductor 250 for limiting, for example, the other end of the conductor 250 is threaded, the second limiting member 240 is a nut, the second limiting member 240 is threadedly connected to the conductor 250, thereby limiting the conductor 250. In addition, the other end of the conductor 250 is electrically connected to the device to facilitate the current transmission process; or a wire can be directly connected to the first transmission rod 321 and extended to the outside through the transmission end 101 to be electrically connected to the device.

[0042] In some embodiments, to facilitate contact between the movable electrode tip 400 and the skin, the sidewall of the connecting end 301 is flush with the sidewall of the movable electrode tip 400 near the axis of the grip portion 100. Specifically, when the contact surface 401 contacts the skin, the contact area of ​​the movable electrode tip 400 away from the connecting end 301 is larger. Therefore, under the reaction force of the skin, the movable electrode tip 400 is more likely to rotate and thus fit against the skin. In addition, the contact surface 401 has an initial angle with the horizontal plane, which is greater than 0° and less than 90°. It can be 3°, 5° or other degrees. At the same time, to facilitate contact between the contact surface 401 and the skin, the initial angle is set to be less than 30°, so that the movable electrode tip 400 can rotate after the contact surface 401 contacts the skin, thereby increasing the contact area between the contact surface 401 and the skin. In addition, since the sidewall of the connecting end 301 is flush with the sidewall of the movable electrode tip 400 near the axis of the grip portion 100, and the weight of the portion of the movable electrode tip 400 away from the connecting end 301 is greater than the weight of the portion near the connecting end 301, the contact surface 401 has an initial angle when the movable electrode tip 400 is not in contact with the skin, so that the contact surface 401 can rotate after contacting the skin to adapt to different skin positions. More specifically, the connecting end 301 is chamfered or arc-shaped to facilitate the rotation of the movable electrode tip 400.

[0043] In some specific embodiments, a connecting block is integrally formed on the end face of the movable electrode tip 400 away from the contact surface 401. The connecting block is rotatably connected to the connecting end 301 via a pivot, and the cross-section of the connecting block is "C"-shaped. Its opposite sidewall is rotatably connected to the connecting end 301 via a pivot, while the remaining sidewall abuts against the sidewall of the connecting section to limit the initial position of the movable electrode tip 400, giving the contact surface 401 an initial included angle, without affecting the process of the contact surface 401 contacting the skin. More specifically, the connecting end 301 has a chamfer or is arc-shaped to facilitate the rotation of the movable electrode tip 400.

[0044] In some specific embodiments, a connecting block is integrally formed on the end face of the movable electrode 400 away from the contact surface 401. The connecting block consists of two plates arranged opposite each other with a gap between them. The connecting end 301 is located in the gap and is rotatably connected to the connecting block via a rotating shaft. The connecting end 301 has a chamfer or is arc-shaped to facilitate the rotation of the movable electrode 400. The end face of the movable electrode 400 away from the contact surface 401 abuts against the top of the connecting end 301 to limit the movable electrode 400 and give it an initial included angle. The connecting end 301 corresponds to the inner side of the movable electrode 400, that is, the sidewalls where the two opposite movable electrode 400s approach each other, to facilitate the rotation of the movable electrode 400.
