[0039] With the development of the medical aesthetics industry, postpartum rehabilitation and intimate care projects have also seen significant growth, especially with the increasing availability of products such as radiofrequency intimate electrodes.

[0040] However, most current intimate electrode products are quite similar, consisting of a handle and an intimate electrode consumable. Due to limitations in the existing structure, the intimate electrode consumable includes a plastic treatment head body and electrode pads, with the electrode pads fixed to the plastic treatment head body. Changing the size of the electrode pads requires replacing the entire intimate electrode consumable, thus increasing costs.

[0041] This utility model proposes a cavity treatment head 10 and a cavity treatment device, which aims to facilitate the replacement of electrode specifications and save treatment costs.

[0042] Please see Figures 2 to 5 In one embodiment of the present invention, the cavity treatment head 10 includes a treatment head body 11 and an electrode module 12. The treatment head body 11 has an open receiving cavity, and the side wall of the receiving cavity is provided with an assembly hole 111. The assembly hole 111 has an opening exposed in the treatment head body 11. The electrode module 12 is detachably connected to the assembly hole 111 through the opening exposed in the treatment head body 11.

[0043] In this embodiment, the treatment head body 11 is made of plastic, such as polyethylene or polypropylene, which is lightweight, durable, easy to process, and has a certain degree of softness and self-lubrication, allowing it to be inserted more smoothly into the cavity to be treated, reducing patient pain. It is understood that soft rubber materials, such as rubber or silicone, can also be used. The treatment head body 11 has a smooth cylindrical shape, with a smooth semi-circular end, allowing it to be inserted more smoothly into the cavity to be treated, improving the patient's treatment experience. A through mounting hole 111 is provided on the treatment head body 11, allowing the electrode module 12 to be detachably installed in the mounting hole 111. Because the treatment head body 11 is made of plastic or soft rubber, it has a certain degree of elasticity, which allows the electrode module 12 to be held in place, thus achieving assembly between the electrode module 12 and the treatment head body 11. The electrode module 12 can be made entirely of metal, such as stainless steel, to provide conductivity for electrical stimulation or radiofrequency therapy. The electrode module 12 is exposed on the surface of the treatment head body 11 in an arc-shaped manner that conforms to the outer periphery of the treatment head body 11, allowing the treatment head body 11 to be inserted more smoothly into the cavity to be treated, thus improving the patient's treatment experience.

[0044] The technical solution of this utility model achieves the effect of convenient replacement of electrode module 12 by adopting a detachable connection between electrode module 12 and treatment head body 11; by detachably connecting electrode module 12 to different positions of the receiving cavity on treatment head body 11, treatment of different areas of the cavity to be treated can be achieved; by detachably connecting different types of electrode modules 12 (radiofrequency electrode module, electrical stimulation electrode module) to the receiving cavity on treatment head, different types of treatment (radiofrequency therapy, electrical stimulation therapy, etc.) can be achieved, and thus the treatment head can achieve different treatment effects.

[0045] In embodiments of this utility model, the number of electrode modules 12 is at least two, and the at least two electrode modules 12 are of different types or sizes.

[0046] In this embodiment, there are at least two electrode modules 12. Different electrode modules 12 can be of different types, such as radio frequency electrodes or microcurrent electrodes, to provide different treatment modes for patients. Different electrode modules 12 can also be of different sizes to provide different treatment areas for patients.

[0047] In an embodiment of this utility model, the cavity treatment head 10 further includes a protective block 13; there are multiple assembly holes 111, which are spaced apart on the side wall of the receiving cavity. Each assembly hole 111 can be detachably installed with a protective block 13 or an electrode module 12, and at least one assembly hole 111 can be detachably installed with an electrode module 12.

[0048] In this embodiment, there are multiple mounting holes 111, protective blocks 13, and electrode modules 12. Multiple mounting holes 111 are spaced apart on the sidewall of the receiving cavity. The electrode modules 12 or protective blocks 13 are detachably connected to the mounting holes 111. The electrode modules 12 can be freely installed in any mounting hole 111 as needed, thus allowing for flexible selection of the treatment position within the cavity. By installing different electrode modules 12 in different mounting holes 111, localized point treatment or combined treatment can be achieved, enriching the functionality of the cavity treatment head 10. Other mounting holes 111 that do not require electrode modules 12 can be replaced by a protective block 13 to seal the mounting hole 111 and prevent bodily fluids from entering the receiving cavity within the treatment head body 11.

[0049] In the embodiments of this utility model, the protective block 13 has the same shape as the electrode module 12, and the protective block 13 is made of insulating material.

[0050] In this embodiment, the shape of the protective block 13 is consistent with the shape of the electrode module 12, so that the overall appearance of the cavity treatment head 10 is consistent. The protective block 13 should be made of insulating material, such as hard plastic or rubber, to prevent the protective block 13 from conducting electricity and causing additional treatment to areas that do not need treatment.

[0051] In an embodiment of this utility model, a plurality of assembly holes 111 are symmetrically opened on opposite side walls of the receiving cavity with the plane containing the axis of the treatment head body 11 as the center of symmetry.

[0052] Multiple assembly holes 111 located on the same side of the receiving cavity are evenly distributed at intervals.

[0053] In this embodiment, the multiple assembly holes 111 are divided into two groups. The two groups of assembly holes 111 are symmetrically opened on the opposite side walls of the treatment head body 11 with the axis of the treatment head body 11 as the center of symmetry. When an electrode module 12 is provided in each assembly hole 111, the multiple electrode modules 12 can also be symmetrically arranged on the opposite side walls of the treatment head body 11 with the axis of the treatment head body 11 as the center of symmetry, so that the opposite sides of the cavity can be treated at the same time, thereby improving the treatment efficiency.

[0054] Multiple mounting holes 111 located on the same side of the treatment head body 11 are evenly distributed. When an electrode module 12 is installed in each mounting hole 111, the multiple electrode modules 12 located on the same side of the treatment head body 11 are also evenly distributed, which can achieve uniform treatment of cavity points and improve the treatment effect.

[0055] In an embodiment of this utility model, the electrode module 12 includes an electrode and a contact 123. The electrode and the contact 123 are electrically connected. The electrode is detachably installed in the mounting hole 111 and exposed through the mounting hole 111. The contact 123 is accommodated in the mounting hole 111 and faces the receiving cavity.

[0056] In this embodiment, the electrode module 12 includes an electrically connected electrode and a contact 123. The electrode is used to be detachably connected to the mounting hole 111. The detachable connection between the electrode and the mounting hole 111 can be an interference fit between the mounting hole 111 and the electrode, with the electrode fixed by the elasticity of the treatment head body 11 itself, or it can be a plug-in connection. The contact 123 faces the receiving cavity and is used to contact the contact 2211 on the circuit board 221 to realize the conduction of current.

[0057] In an embodiment of this utility model, the electrode module 12 includes a base 121, an electrode sheet 122, and electrodes 122 and contacts 123 are respectively disposed on opposite surfaces of the base 121. The electrode sheet 122 and the contacts 123 are electrically connected. The base 121 is detachably installed in the mounting hole 111. The electrode sheet 122 is exposed through the mounting hole 111, and the contacts 123 are accommodated in the mounting hole 111 and face the receiving cavity.

[0058] In this embodiment, the electrode module 12 includes a base 121, electrode pads 122, and contacts 123. The base 121 is detachably connected to the mounting hole 111. The detachable connection between the base 121 and the mounting hole 111 can be an interference fit between the mounting hole 111 and the base 121, where the base 121 is fixed by the elasticity of the treatment head body 11 itself, or it can be a plug-in connection. The base 121 also serves to support the electrode pads 122 and contacts 123. The electrode pads 122 and contacts 123 are disposed on opposite surfaces of the base 121, with the contacts 123 exposed in the mounting hole 111 facing the receiving surface. At the edge of the cavity, the electrode pad 122 is exposed at the edge of the mounting hole 111 away from the receiving cavity. The contact 123 is electrically connected to the electrode pad 122 and electrically connected to the circuit board 221 on the handle 20 through the contact 123, thus establishing a conductive circuit and realizing the electrical connection between the electrode pad 122 and the circuit board 221 for radiofrequency therapy or electrical stimulation therapy to the patient. Compared with the existing electrode pad 122 being electrically connected to the circuit board 221 through wires, the electrode pad 122 is electrically connected to the circuit board 221 through contact 123, which allows for detachable connection of the electrode pad 122 for quick replacement. The electrical connection between the contact 123 and the electrode pad 122 can be achieved by using a conductive metal material for the base 121, directly conducting electricity between the contact 123 and the electrode pad 122 through the base 121, or by making the base 121 hollow, with wires inside the base 121 conducting electricity between the contact 123 and the electrode pad 122. No further limitation is made here.

[0059] In an embodiment of this utility model, a groove 1211 is provided on each of the opposite sides of the base 121, and a boss 1111 is provided on each of the opposite two hole walls of the assembly hole 111; or a boss 1111 is provided on each of the opposite sides of the base 121, and a groove 1211 is provided on each of the opposite two hole walls of the assembly hole 111; the boss 1111 and the groove 1211 are engaged to connect the base 121 and the assembly hole 111.

[0060] In this embodiment, a groove 1211 is formed on each of the opposite sides of the base 121. Correspondingly, a boss 1111 is provided on each of the opposite walls of the mounting hole 111. When the base 121 is inserted into the mounting hole 111, a boss 1111 engages with a groove 1211, increasing the connection strength between the base 121 and the mounting hole 111 and preventing the electrode module 12 from falling off during treatment. It can be understood that the groove 1211 can also be formed on the opposite walls of the mounting hole 111, and correspondingly, the boss 1111 is provided on each of the opposite sides of the base 121.

[0061] Please see Figure 1 and Figure 6In an embodiment of this utility model, the cavity treatment head 10 further includes a handle 20. The handle 20 includes a gripping part 21 and an insertion part 22 connected as one piece. The insertion part 22 is provided with a circuit board 221. The insertion part 22 passes into the receiving cavity and makes the circuit board 221 electrically connected to the electrode module 12. The gripping part 21 is detachably connected to the cavity treatment head 10.

[0062] In this embodiment, the gripping part 21 and the insertion part 22 of the handle 20 can be integrally molded by injection molding, or they can be separate parts connected by threads, snaps, or screws. The insertion part 22 is provided with a circuit board 221, which is used to insert into the treatment head body 11 of the cavity treatment head 10, so that the handle 20 and the cavity treatment head 10 are connected to form a treatment handpiece. The circuit board 221 is electrically connected to the electrode module. The electrical connection can be made by means of spring pins or spring sheets, etc., and is not further limited here. The cavity treatment head 10 is a consumable part and is detachably connected to the handle 20. It is replaced after each use, which is clean and hygienic and reduces the risk of cross-infection.

[0063] The grip 21 and the cavity treatment head 10 are detachably connected. This can be achieved by using a locking structure to connect the grip 21 and the treatment head body 11 into one unit, further preventing the treatment head body 11 from falling off the grip 21 during use, thereby preventing treatment interruption and improving the reliability and stability of the treatment hand. Alternatively, a plug-in or snap-fit ​​connection can be used to connect the grip 21 and the treatment head body 11 into one unit.

[0064] In an embodiment of this utility model, a plurality of contacts 2211 are protruding from the circuit board 221. The plurality of contacts 2211 are spaced apart and electrically connected to the circuit board 221. One contact 2211 abuts against a contact point 123 so that the electrode module 12 is electrically connected to the circuit board 221.

[0065] In this embodiment, the circuit board 221 is provided with a plurality of contacts 2211 that are electrically connected to the circuit board 221. The contacts 2211 can be spring pins or spring sheets, etc. The plurality of contacts 2211 are spaced apart, that is, the spacing distance with the electrode module 12 is the same. When the insertion part 22 is inserted into the receiving cavity, one contact 2211 corresponds to one electrode module 12 and abuts against the contact 123 to electrically conduct the circuit board 221 and the electrode sheet 122.

[0066] In an embodiment of this utility model, the gripping part 21 has a buckle, and the cavity treatment head 10 has a slot. When the insertion part 22 is inserted into the receiving cavity, the buckle engages with the slot, so that the gripping part 21 and the cavity treatment head 10 are detachably connected.

[0067] In this embodiment, a buckle is provided on the grip 21, and a slot is provided on the treatment head body 11. When the cavity treatment head 10 is installed on the grip 21, the buckle engages with the slot to detachably connect the treatment head body 11 and the grip 21, facilitating the replacement of the new cavity treatment head 10, improving hygiene, and reducing cross-infection. In a preferred embodiment, a button linked to the buckle is also included. When the button is pressed, the buckle moves along with the button. After pressing the button, the buckle can be dislodged from the slot, separating the treatment head body 11 from the grip 21, allowing for the replacement of the new cavity treatment head 10, improving hygiene, and reducing the occurrence of cross-infection.

[0068] Please see Figures 7 to 11 The present invention also proposes an electrode removal tool 30, which is used for the cavity treatment head 10 as described above. The electrode removal tool 30 includes a hand-held part 31 and a removal part 32 connected as one piece.

[0069] In this embodiment, the electrode removal tool 30 includes an integrally formed handheld part 31 and a removal part 32. By holding the handheld part 31, the removal part 32 is inserted into the receiving cavity of the treatment head body 11, and the electrode module 12 is pushed out of the assembly hole 111, achieving rapid disassembly of the electrode module 12, reducing patient waiting time, and improving treatment efficiency. The electrode removal tool 30 is an accessory sold together with the cavity treatment head 10. Operators can use the electrode removal tool 30 to achieve rapid disassembly when changing the type or position of the electrode module 12 or changing the position of the protective block 13.

[0070] In an embodiment of this utility model, the removal part 32 is provided with a protrusion 321 extending outward along its circumference. The removal part 32 has a first state and a second state. When the removal part 32 is in the first state, the protrusion 321 moves away from the electrode module 12 and / or the protective block 13. When the removal part 32 is in the second state, the protrusion 321 abuts against the electrode module 12 and / or the protective block 13 and pushes the electrode module 12 and / or the protective block 13 out of the assembly hole 111.

[0071] In this embodiment, the removal part 32 is a round rod structure. The outer periphery of the removal part 32 is provided with a protrusion 321. The shape of the protrusion 321 is elliptical or eccentric. The protrusion 321 of the removal part 32 is inserted into the receiving cavity of the treatment head body 11 and aligned with the electrode module 12. The hand-held part 31 is rotated, thereby driving the removal part 32 to rotate, so that the protrusion 321 is perpendicular to the electrode module 12 and abuts against the electrode module 12. The height of the protrusion 321 is sufficient to push the electrode module 12 out of the assembly hole 111. It can be understood that when there are multiple assembly holes 111, there are also multiple protrusions 321 on the removal part 32, and they correspond one-to-one with the positions of the assembly holes 111. The removal part 32 can push multiple electrode modules 12 out of the assembly holes 111 at the same time. When there are two sets of assembly holes 111, respectively located on opposite side walls of the treatment head body 11, the protrusions 321 on the removal part 32 are also located on opposite sides of the removal part 32. The removal part 32 can simultaneously push out multiple electrode modules 12 from both sides through the assembly holes 111, further improving treatment efficiency. It is understood that in some embodiments, a protective block 13 is installed inside the assembly hole 111. When the protrusion 321 of the removal part 32 is inserted into the receiving cavity of the treatment head body 11 and aligned with the protective block 13, the handle 31 is rotated, thereby driving the removal part 32 to rotate, so that the protrusion 321 is perpendicular to the protective block 13 and abuts against the protective block 13. The height of the protrusion 321 is sufficient to push the protective block 13 out of the assembly hole 111, achieving the effect of quick disassembly.
