[0001] This invention relates to the field of electrostimulation therapy devices, and more particularly to a cavity therapy rod. This invention also relates to an electrostimulation therapy device comprising the aforementioned cavity therapy rod. Background Technology

[0002] Bioelectric feedback involves applying microcurrents to specific muscle groups (electric stimulation therapy) and receiving electromyographic / bioelectric feedback signals from the patient to cause passive muscle contraction, thereby improving contraction strength, duration, and sensitivity, achieving the goal of non-invasive treatment to improve muscle tension.

[0003] In electrical stimulation therapy for human cavities, such as rectal and vaginal electrical stimulation therapy, the focus is mainly on exercising the pelvic floor muscles.

[0004] However, current clinical research has found that low-frequency electrical stimulation can not only exercise muscles, but also activate the pelvic floor nerves or vaginal nerves, releasing various therapeutic factors in the body. This achieves the effect of activating the body's own healing through external stimulation. However, due to the special shape of the rectum and vagina, how to effectively stimulate the rectum or vagina to achieve better therapeutic results is an urgent problem to be solved.

[0019] The second insulating element is threadedly connected to the conductive inner core and abuts against the conductive connector to confine the second electrical stimulation element and the conductive connector between the first insulating element and the second insulating element.

[0022] The barrier pad is located between the first electrical stimulation element and the second electrical stimulation element, and abuts against the first electrical stimulation element and the second electrical stimulation element;

[0023] The sleeve extends between the inner surface of the second electrical stimulation element and the outer surface of the conductive inner core.

[0042] To provide a clearer understanding of the technical features, objectives, and effects of this application, specific embodiments of this application are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0043] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0044] To keep the drawings concise, only the parts relevant to this application are shown schematically in each drawing, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some drawings, only one of the components with the same structure or function is shown schematically, or only one of them is labeled.

[0045] Figure 1 A schematic structural diagram illustrating one embodiment of a cavity therapy rod; Reference Figure 1 The cavity therapy rod includes: a conductive inner core 1, a first electrical stimulation part 2, and a second electrical stimulation part 3.

[0046] The first electrical stimulation part 2 includes a first electrical stimulation element 21, which is disposed at one end of the conductive inner core 1 along the length extension direction of the conductive inner core 1.

[0047] The second electrical stimulation unit 3 includes a second electrical stimulation element 31, which is sleeved on the outer wall of the conductive inner core 1. The second electrical stimulation element 31 is spaced apart from the first electrical stimulation element 21 along the length extension direction of the conductive shaft, and the second electrical stimulation element 31 is electrically insulated from the conductive inner core 1 and the first electrical stimulation element 21. In this arrangement, the first electrical stimulation element 21 and the second electrical stimulation element 31 form a separate electrical stimulation area, so as to perform electrical stimulation treatment on different locations in the patient's rectum or vagina during use.

[0048] Wherein, after the first electrical stimulation element 21 and the second electrical stimulation element 31 are energized, for example, the first electrical stimulation element 21 is connected to an external electrical stimulation therapy device 8 through the conductive inner core 1 (see reference). Figure 12 The end of the second electrical stimulation element 31 that is away from the first electrical stimulation element 21 is connected to an external electrical stimulation therapy device.

[0049] The first electrical stimulator 21 and the second electrical stimulator 31 can alternately output electrical stimulation pulses sufficient to induce muscle contraction (i.e., the first electrical stimulator 21 and the second electrical stimulator output biphasic electrical stimulation pulses), and after the electrical stimulation pulses pass through human tissue, they flow into the first electrical stimulator 2 or the second electrical stimulator 3 that does not output electrical stimulation pulses, so as to form a current loop.

[0050] For example, when the first electrical stimulation unit 2 outputs electrical stimulation pulses (current), it is the positive electrode, and the second electrical stimulation unit 3 is the negative electrode. After passing through the human tissue, the electrical stimulation pulses (current) flow into the second electrical stimulation unit 3 to form a closed circuit loop. Conversely, when the second electrical stimulation unit 3 outputs electrical stimulation pulses (current), the second electrical stimulation unit 3 is the positive electrode, and the first electrical stimulation unit 2 is the negative electrode. After passing through the human tissue, the electrical stimulation pulses (current) flow into the first electrical stimulation unit 2 to form a closed circuit loop. Under this setting, the first electrical stimulation unit 2 and the second electrical stimulation unit 3 alternately output electrical stimulation pulses to achieve electrical stimulation of the patient's rectal tissue, nerves, or vaginal tissue and nerves, activating the human body to release various therapeutic factors to achieve the purpose of treatment. Furthermore, the alternating output of electrical stimulation pulses (current) by the first electrical stimulation unit 2 and the second electrical stimulation unit 3 can also neutralize the residual charge in the human tissue, thereby reducing the risk of tissue damage to the patient under electrical stimulation.

[0051] like Figure 1 , Figure 2 As shown, the conductive inner core 1 has a first end 11 connected to the first electrical stimulation element 21, and the other end opposite to the first end 11 is the second end 12. The second end 12 of the conductive inner core 1 is provided with a first electrode connecting shaft 13. The conductive inner core 1 is connected to an external electrical stimulation therapy device 8 through the first electrode connecting shaft 13 so that the first electrical stimulation element 21 can output electrical stimulation pulses (current).

[0052] like Figure 2 , Figure 3 As shown, the second electrical stimulation unit 3 also includes a conductive connector 32, wherein the conductive connector 32 is connected to the end of the second electrical stimulation element 31 away from the first electrical stimulation element 21 and is insulated from the conductive inner core 1. The conductive connector 32 has a second electrode connecting shaft 33. In use, a therapeutic instrument can be connected to the second electrical stimulation element 31 through the second electrode connecting shaft 33 so that the second electrical stimulation element 31 can output electrical stimulation pulses (current). Specifically, the conductive connector 32 and the second electrical stimulation element 31 are integrally connected, and the second electrode connecting shaft 33 and the conductive connector 32 can be connected by a threaded connection or a plug-in connection.

[0053] In other embodiments, reference is made to Figure 4 , Figure 5 The conductive connector 32 is an independent component and is sleeved on the conductive inner core 1. The conductive connector 32 abuts against the second electrical stimulation element 31. The conductive connector 32 has a second electrode connecting shaft 33 for connecting the electrical stimulation therapy device 8, and the conductive connector 32 is electrically connected to the second electrical stimulation element 31. The conductive connector 32 and the second electrical stimulation element 31 are both insulated from the power supply of the conductive inner core 1, so that the first electrical stimulation element 21 and the second electrical stimulation element 31 are independent of each other. In use, the therapy device is externally connected through the first electrode connecting shaft 13 and the second electrode connecting shaft 33, so that the first electrical stimulation element 21 and the second electrical stimulation element 31 form mutually spaced electrical stimulation areas.

[0054] refer to Figure 2 The connection method between the first electrical stimulation element 21 and the conductive inner core 1 is explained as follows: The first electrical stimulation element 21 has an insertion end and a connection end. In use, it is inserted into the patient's rectum or vagina with the insertion end as the starting end.

[0055] Among them, reference Figure 2 A threaded hole is provided from the connecting end to the insertion end, and an external thread is provided on the outer wall of the conductive inner core 1. Part of the conductive inner core 1 is screwed into the threaded hole, thereby forming a connection between the first electrical stimulation element 21 and the conductive inner core 1. In use, a treatment device is connected to the device through the first electrode connecting shaft 13. The treatment device outputs electrical stimulation pulses (currents). After passing through the conductive inner core 1, the output electrical stimulation pulses (currents) are output by the first electrical stimulation element 21 to the patient's rectum or vaginal tissue, thereby providing electrical stimulation to the patient's rectum or vaginal tissue. In this configuration, the first electrical stimulation element 21 can also be disassembled from the conductive inner core 1 for easy replacement.

[0056] Correspondingly, the first electrical stimulation element 21 is provided in different models. Each model of the first electrical stimulation element 21 has a different outer diameter and length. When using it, the appropriate model of the first electrical stimulation element 21 can be selected according to the different insertion sites or the different body shapes of the patients.

[0057] Alternatively, the first electrical stimulation element 21 is welded to the end of the conductive inner core 1 away from the first electrode connecting shaft 13.

[0058] Alternatively, the first electrical stimulation element 21 is integrally connected with the conductive inner core 1, wherein the first electrical stimulation element 21 is installed at the end of the conductive inner core 1 away from the first electrode connecting shaft 13.

[0059] refer to Figure 5 The second electrical stimulation element 31 has a first through hole 311 through which it is sleeved on the conductive inner core 1. Specifically, the inner diameter of the first through hole 311 is larger than the outer diameter of the conductive inner core 1. In this way, although the second electrical stimulation element 31 is sleeved on the outer surface of the conductive inner core 1, it can still not be electrically connected to the conductive inner core 1.

[0060] The conductive connector 32 has a second through hole 321 through which it is sleeved on the conductive inner core 1. Similarly, the inner diameter of the second through hole 321 is larger than the outer diameter of the conductive inner core 1. In this way, although the conductive connector 32 is sleeved on the outer surface of the conductive inner core 1, it can still not be electrically connected to the conductive inner core 1.

[0061] Specifically, the conductive inner core 1 is made of copper to ensure good conductivity; the first electrical stimulation element 21 and the second electrical stimulation element 31 are both made of medical stainless steel to ensure good output of electrical stimulation pulses.

[0062] refer to Figure 6 To achieve insulation between the second electrical stimulation element 31, the conductive connector 32, the conductive inner core 1, and the first electrical stimulation element 21 during power supply, such as Figure 6 , Figure 7 As shown, the cavity therapy rod also includes a first insulating member 4 and a second insulating member 5. The first insulating member 4 is sleeved on the conductive inner core 1 and located between the first electrical stimulation member 21 and the second electrical stimulation member 31. The first insulating member 4 abuts against the first electrical stimulation member 21 and the second electrical stimulation member 31 respectively. This achieves the separation of the first electrical stimulation member 21 and the second electrical stimulation member 31 in the length extension direction of the conductive inner core 1, thereby avoiding direct electrical conduction between the first electrical stimulation member 21 and the second electrical stimulation member 31 and short circuit heating.

[0063] refer to Figure 7 The second insulating member 5 is threadedly connected to the conductive inner core 1 and abuts against the conductive connector 32. When the second insulating member 5 is screwed onto the conductive inner core 1, it also causes the conductive connector 32 to move towards the second electrical stimulation member 31 until the second electrical stimulation member 31 presses against the first insulating member 4, thus confining the second electrical stimulation member 31 and the conductive connector 32 between the first insulating member 4 and the second insulating member 5. As will be understood by those skilled in the art, the inner surface of the second electrical stimulation member 31 and the inner surface of the conductive connector 32 do not contact the inner surface of the conductive inner core 1, i.e., the second... The inner diameter of the first through-hole 311 of the electrical stimulation element 31 and the inner diameter of the second through-hole 321 of the conductive connector 32 are both larger than the outer diameter of the conductive inner core 1, so that the second electrical stimulation element 31 and the conductive connector 32 are not connected to the conductive inner core 1. In this configuration, after the first electrode connecting shaft 13 and the second electrode connecting shaft 33 are respectively connected to the treatment device, they can output electrical stimulation pulses (currents) respectively, so that the first electrical stimulation element 21 and the second electrical stimulation element 31 respectively form electrical stimulation areas, thereby stimulating the patient's rectal or vaginal tissue over a large area.

[0064] refer to Figure 7 More specifically, the first insulating element 4 is a circular gasket with a through hole. The first insulating element 4 is sleeved on the conductive inner core 1 through the first through hole. A first sleeve is provided on one side of the first insulating element 4. The first sleeve extends into the first through hole 311 of the second electrical stimulation element 31, thereby isolating the inner surface of the second electrical stimulation element 31 from the outer surface of the conductive inner core 1.

[0065] The second insulating member 5 is provided with a threaded channel. The second insulating member 5 is screwed into the conductive inner core 1 through the threaded channel. One end of the second insulating member 5 is provided with a second sleeve. The second sleeve extends into the second through hole 321 of the conductive connector 32, thereby isolating the inner surface of the conductive connector 32 from the outer surface of the conductive inner core 1.

[0066] In another embodiment, to achieve insulation between the second electrical stimulation element 31, the conductive connector 32, the conductive inner core 1, and the first electrical stimulation element 21 during power supply, reference is made. Figure 8 , Figure 9 In this embodiment, the cavity treatment rod further includes: an insulating pad 6, a first insulating sleeve 61, and a second insulating sleeve 62. The insulating pad 6 is sleeved on the conductive inner core 1 and located between the first electrical stimulation element 21 and the second electrical stimulation element 31, and the insulating pad 6 abuts against the first electrical stimulation element 21 and the second electrical stimulation element 31 respectively.

[0067] The first insulating sleeve 61 is installed in the first through hole 311 of the second electrical stimulation element 31, wherein the first insulating sleeve 61 is for the conductive inner core 1 to pass through. Specifically, the first insulating sleeve 61 can be fixed in the first through hole 311 by adhesive bonding.

[0068] The second insulating sleeve 62 is installed in the second through hole 321 of the conductive connector 32. Specifically, the first insulating sleeve 61 can be fixed in the first through hole 311 by adhesive bonding.

[0069] The inner surface of the second insulating sleeve 62 is provided with an internal thread, and the conductive connector 32 is screwed onto the conductive inner core 1 through the internal thread of the second insulating sleeve 62.

[0070] In another implementation, refer to Figure 10 , Figure 11 The insulating component has a sleeve section 7 and a barrier pad 71 disposed at one end of the sleeve section 7. A connecting channel is provided through the barrier pad 71 in the direction of the sleeve section 7. The insulating component is sleeved on the outside of the conductive inner core 1 through the connecting channel.

[0071] The barrier pad 71 is located between the first electrical stimulation element 21 and the second electrical stimulation element 31, and abuts against the first electrical stimulation element 21 and the second electrical stimulation element 31.

[0072] The socket 7 extends between the inner surface of the second electrical stimulation element 31 and the outer surface of the conductive inner core 1.

[0073] Specifically, the inner surface of the socket segment 7 is provided with an internal thread, and it is screwed onto the outer wall of the conductive inner core 1 through the internal thread until the barrier pad 71 abuts against the end of the first electrical stimulation element 21 that is close to the second electrical stimulation element 31.

[0074] The outer surface of the sleeve section 7 is also formed with at least one external thread. The inner wall of the second through hole of the conductive connector 32 is formed with an internal thread that engages with the external thread. The conductive connector 32 is screwed onto the outside of the sleeve section 7 through the engagement of the internal thread and the external thread. The conductive connector 32 abuts against the end of the second electrical stimulation element 31, thereby making the conductive connector 32 and the second electrical stimulation element 31 electrically connected. At the same time, the cooperation between the conductive connector 32 and the sleeve section 7 also restricts the second electrical stimulation element 31, preventing the second electrical stimulation part 3 from sliding in the length extension direction of the conductive inner core 1.

[0075] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 On a cross-section perpendicular to the length extension direction of the conductive inner core 1, the contours of the first electrical stimulator 21 and the second electrical stimulator 31 are regularly undulating arcs, forming several peaks and several valleys located between adjacent peaks. In this configuration, when the outer surfaces of the first electrical stimulator 21 and the second electrical stimulator 31 come into contact with human tissue, the contact surfaces between the peaks and valleys and the human tissue are different, thereby causing interface impedance differences at various positions on the outer surfaces of the first electrical stimulator 21 and the second electrical stimulator 31. This results in potential differences at various positions on the outer surfaces of the first electrical stimulator 21 and the second electrical stimulator 31, allowing the patient to experience different degrees of electrical stimulation at the corresponding peaks and valleys. This enhances the patient's proprioceptive input, further improves the electrical stimulation effect, and is more conducive to activating the release of various therapeutic factors in the human body, thereby improving the body's self-healing ability.

[0076] refer to Figure 1 , Figure 2 Specifically, both the first electrical stimulator 21 and the second electrical stimulator 31 have six spherical surfaces 213 formed on their outer surfaces. Each spherical surface 213 has a peak at its apex and a valley between adjacent spherical surfaces 213. The insertion end of the first electrical stimulator 21 is a spherical surface 213, making it easier to insert into the patient's rectum or vagina during use. Furthermore, the smooth spherical surfaces 213 prevent scratching of internal tissues during insertion. Of course, those skilled in the art will understand that the number of spherical surfaces 213 on the first and second electrical stimulators 21 and 31 is not limited to the above number and can be increased or decreased according to the actual design. The specific number of spherical surfaces 213 depends on the length of the first and second electrical stimulators 21 and the diameter of the spherical surfaces 213.

[0077] refer to Figure 1 In the length extension direction of the conductive inner core 1, the spherical surfaces 213 on the first electrical stimulation element 21 and the spherical surfaces 213 on the second electrical stimulation element 31 are arranged in a linear array.

[0078] In this configuration, the outer surfaces of the first electrical stimulation element 21 and the second electrical stimulation element 31 are uneven. After being inserted into the patient's rectum or vagina, the first electrical stimulation element 21 and the second electrical stimulation element 31 fit into the direction of the rectal wall folds or vaginal wall folds, thereby reducing the displacement of the device as a whole in the patient's rectum or vagina.

[0079] This application also provides an electrical stimulation therapy device, such as... Figure 12 As shown, the electrostimulation therapy device 8 includes: a main body of the device and the aforementioned cavity therapy rod. The main body of the device is connected to the cavity therapy rod by wires. Specifically, a first wire is used to connect the first electrode connecting shaft 13 to the main body of the device, and a second wire is used to connect the second electrode connecting shaft 33 to the main body of the device. In this way, under the control of the main body of the device, the first electrostimulation element 21 and the second electrostimulation element 31 of the cavity therapy rod alternately output electrostimulation pulses.

[0080] It should be understood that although this specification describes various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0081] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of this application and are not intended to limit the scope of protection of this application. All equivalent implementations or modifications made without departing from the spirit of the art of this application, such as combinations, divisions or repetitions of features, should be included within the scope of protection of this application.
