[0033] See Figures 1-9 This invention provides a therapeutic probe, comprising a probe body 1, which is a flexible probe. A cavity 11 is formed inside the probe body 1, and one end of the probe body 1 has an opening communicating with the cavity 11. Several protruding structures 2 are provided on the sidewall of the probe body 1, which are used to contact the affected area. The probe body 1 has a first usage state and a second usage state. In the first usage state, the protruding structures 2 face outwards from the probe body 1; in the second usage state, the protruding structures 2 face the cavity 11. In the first usage state, the probe body 1 is used facing forward and can be inserted into the human body. The protruding structures 2 contact the internal cavity of the human body to achieve the therapeutic function. The probe body 1 can also be used for external skin treatment, such as on the face. In the second usage state, the probe body 1 is used with its side turned up, fitted onto the affected area, such as the male genitalia. In this state, the protruding structures 2 face the internal cavity 11 of the probe body 1 and can contact the human body part located within the cavity 11 to achieve the therapeutic function. The probe body 1 of this invention has a flexible structure, which can reduce patient discomfort and avoid secondary damage to the affected area when placed inside the body. In addition, the treatment probe of this invention has multiple usage states, and can be used both inside and outside the body, making it versatile and able to meet diverse treatment needs.

[0034] Because the probe body 1 is a flexible probe, it can be flipped over to switch from the first use state to the second use state.

[0035] It should be noted that the probe body 1 is a soft and shrinkable thin film or colloid, and several protruding structures 2 are distributed on the local or overall sidewall of the probe body 1. The protruding structures 2 are treatment protrusions, which can release radio frequency, pulse voltage and current, high and low voltage and current, microwave or electromagnetic effects, etc. By contacting the affected area with the treatment protrusions, treatment of the affected area can be achieved. Among them, the pulse voltage and current include pulse therapy of various frequency bands, such as unipolar pulse, bipolar pulse, low voltage pulse, high voltage pulse, nanosecond pulse, microsecond pulse, etc., and the electromagnetic effects include bioelectromagnetic effects or electromagnetic wave correlation effects, etc. The therapeutic function is achieved by contacting the affected area.

[0036] Specifically, in the first state of use, a filling medium is injected through the opening of the probe body 1. The filling medium enters the cavity 11, causing the entire probe body 1 to expand and deform. The probe body 1 exerts a compressive force on the affected area located outside the probe body 1, which facilitates the application of current, radio frequency, pulse voltage current, high, medium and low voltage, microwave, electromagnetic or resistive forces released by the protruding structure 2 to the affected area, achieving a better therapeutic effect. The filling medium can be a gas, liquid or oily substance.

[0037] Furthermore, the protruding structure 2 can specifically be at least one of the following structures: a protrusion, a vertical protrusion, an annular protrusion, or an annular piece. In some other embodiments, the protruding structure 2 can also be a structure of other shapes. The outer wall surface of the protruding structure 2 can protrude beyond the outer wall surface of the probe body 1, or it can be flush with the outer wall surface of the probe body 1. Figure 1 As shown, the raised structure 2 consists of protrusions, and multiple protrusions are arranged in an array on the outer wall of the probe body 1. The number of protrusions can be set to different values ​​according to actual needs; for example... Figure 5 As shown, the protruding structure 2 is a vertical ridge, with multiple vertical ridges arranged circumferentially on the outer wall of the probe body 1. The number of vertical ridges can be set to different values ​​according to actual needs, and the spacing between every two vertical ridges can be adjusted according to actual needs; for example... Figure 8 As shown, the protruding structure 2 is an annular protrusion, each annular protrusion being formed by at least two circumferentially spaced arc-shaped protrusions. Multiple annular protrusions are axially arranged on the outer wall of the probe body 1. The number of annular protrusions can be set to different values ​​according to actual needs. The use of multiple arc-shaped protrusions to form the annular protrusions reduces the difficulty of the manufacturing process; for example... Figure 9As shown, the protruding structure 2 is an annular piece. Multiple annular pieces are arranged axially on the outer wall of the probe body 1. The annular pieces may or may not have protrusions. Treatment is achieved by direct contact between the annular pieces and the affected area. The number of annular pieces can be set to different values ​​according to actual needs. Multiple annular pieces set on the same probe body 1 can be set to the same size or different sizes.

[0038] Specifically, each protrusion structure 2 can be controlled independently, and multiple protrusion structures 2 on the same treatment probe can release different treatment signal waves, enabling mixed treatment.

[0039] Furthermore, a detachable guide rod 3 is provided at the other end of the probe body 1. In the first use state, the guide rod 3 is located in the cavity 11 and is used to guide the probe body 1 into the body. The length of the guide rod 3 extending into the cavity 11 is less than the length of the probe body 1. Before use, the probe body 1 is in a folded state. The free end of the guide rod 3 is connected to the treatment device. After the guide rod 3 guides part of the probe body 1 into the human body cavity, a filling medium is injected into the cavity 11 of the probe body 1, so that the probe body 1 can extend forward under the action of the fluid. When the length of the cavity that the probe body 1 needs to enter is greater than the length of the guide rod 3, after the probe body 1 enters to a certain depth, under the action of the flow impact force of the filling medium, the guide rod 3 can detach from the probe body 1, so that the probe body 1 can continue to extend forward, which is beneficial for use in relatively long cavities such as the intestine.

[0040] Specifically, the guide rod 3 is provided with a drainage hole 31, which passes through both ends of the guide rod 3 and can be used to convey the filling medium.

[0041] Furthermore, a barrier 5 is fitted onto the guide rod 3, and the barrier 5 slides along the guide rod 3 to divide the cavity 11 into at least two independent chambers.

[0042] Furthermore, the barrier 5 has a pouch structure, with an input port 51 and an output port 52. Both the input port 51 and the output port 52 communicate with the inner cavity of the barrier 5. The input port 51 is used to deliver filling medium into the inner cavity of the barrier 5, and the output port 52 is used to discharge the filling medium from the barrier 5. By injecting filling medium into the barrier 5 through the input port 51, the barrier 5 can expand and enlarge, compressing the side wall of the probe body 1, allowing the probe body 1 to expand locally outward, thus achieving local compression of the affected area.

[0043] In some other embodiments, the outer wall of the barrier 5 is close to the inner wall of the probe body 1. By sleeved with an ultrasonic ring on the outside of the probe body 1, the ultrasonic waves emitted by the ultrasonic ring cause the outer wall of the barrier 5 to fuse and fix with the inner wall of the probe body 1, thereby sealing the barrier 5 and dividing the cavity 11 into at least two independent chambers. A filling medium can be introduced into part of the chambers to achieve local expansion of the probe body 1.

[0044] In one specific embodiment, the guide rod 3 has several second grooves distributed axially on its side wall. The wall thickness of the guide rod 3 at the location of the second groove is much smaller than the wall thickness of the guide rod 3 at the location without the second groove. Bending the location of the first groove 181 can cause the bottom wall of the second groove to crack, making the second groove a through hole communicating with the drainage hole 31. When it is necessary to locally deliver the filling medium to a certain location, the bottom wall of the second groove at the corresponding location is broken to achieve local delivery of the filling medium.

[0045] Specifically, the treatment probe is connected to the treatment device, which provides power to the treatment probe and delivers the filling medium. The filling medium inside the treatment probe can also flow back into the treatment device, thereby achieving the discharge of the filling medium inside the treatment probe.

[0046] Furthermore, the other end of the probe body 1 is provided with a connecting part 18, and a first connecting structure 182 is provided on the outer wall of the connecting part 18. One end of the guide rod 3 is provided with a second connecting structure 32, and the first connecting structure 182 and the second connecting structure 32 are detachably connected. Specifically, the connection between the first connecting structure 182 and the second connecting structure 32 is a threaded connection. The first connecting structure 182 is a first external thread provided on the outer wall of the connecting part 18, and the second connecting structure 32 is a first internal thread provided on the end wall of the drainage hole 31 of the guide rod 3. The first internal thread and the first external thread are engaged. The guide rod is connected to the outer wall of the connecting part 18, which facilitates observation of the screw-in length of the guide rod and avoids damage to the probe body 1 by the guide rod.

[0047] In some other embodiments, the connection between the first connecting structure 182 and the second connecting structure 32 is a magnetic connection. The first connecting structure 182 is a first magnetic member disposed on the outer side wall of the connecting part 18, and the second connecting structure 32 is a second magnetic member disposed on the inner wall of the guide rod 3. The connection and disassembly of the probe body 1 and the guide rod 3 are realized through the magnetic attraction between the first magnetic member and the second magnetic member, and the operation is simple.

[0048] In one specific embodiment, see Figure 2The probe body 1 includes a flexible housing 12 and an FPC board 13 embedded in the flexible housing 12. A protruding structure 2 is electrically connected to the FPC board 13 and extends out of the flexible housing 12. The FPC board 13 has good flexibility and insulating structures on both sides, providing good insulation performance. This eliminates the need for an additional insulating layer on the probe body 1, which helps reduce the thickness of the probe body 1 and gives it better expansion and deformation performance.

[0049] Specifically, the FPC is equipped with pressure detection elements and temperature detection elements. When the treatment probe is inserted into the body, the pressure detection elements and temperature detection elements can detect the pressure and temperature inside the body respectively, and feed the detection results back to the treatment device. This allows medical staff to make timely judgments, adjust the injection volume and temperature of the filling medium, and reduce the discomfort caused by the treatment to the patient.

[0050] In one specific embodiment, see Figure 4 and Figure 6 The probe body 1 includes a first thin film layer 14, a conductive layer 15 and a second thin film layer 16. The second thin film layer 16 covers the first thin film layer 14, the conductive layer 15 is disposed on the second thin film layer 16, the protruding structure 2 is electrically connected to the conductive layer 15, and the protruding structure 2 extends out of the second thin film layer 16.

[0051] Specifically, the conductive layer 15 can be an FPC board, a silver nanowire circuit layer, a graphene composite conductive layer, or a liquid metal circuit layer, possessing good conductivity and capable of supplying power to the protruding structure 2. The first thin film layer 14 and the second thin film layer 16 are both insulating layers. When the conductive layer 15 uses conductive structures that do not possess insulating layers themselves, such as silver nanowire circuit layers, graphene composite conductive layers, or liquid metal circuit layers, the first thin film layer 14 and the second thin film layer 16 can act as external insulators, preventing leakage from the probe body 1. The silver nanowire circuit layer can be made of ordinary silver nanowires or a silver nanowire-elastomer composite material. This silver nanowire-elastomer composite material is a novel silver nanowire obtained by adding a soft rubber material to silver nanowires, resulting in better flexibility. The soft rubber material can specifically be a rubber material.

[0052] Furthermore, the open end of the first film layer 14 is connected to the open end of the second film layer 16 so that a sealing cavity 17 is formed between the first film layer 14 and the second film layer 16. In the second use state, the guide rod 3 is used to pierce the first film layer 14 and to deliver the filling medium to the sealing cavity 17.

[0053] Furthermore, the connecting part 18 is provided with a first groove 181, and a third connecting structure 183 is provided in the first groove 181. The other end of the guide rod 3 is provided with a fourth connecting structure 33, and the third connecting structure 183 and the fourth connecting structure 33 are detachably connected. The bottom wall of the first groove 181 overlaps with the first film layer 14. When the guide rod 3 presses the bottom wall of the first groove 181, it presses the first film layer 14.

[0054] Specifically, the thickness of the connecting part 18 is greater than the thickness of the probe body 1, which gives the connecting part 18 a certain degree of rigidity and makes the connection between the guide rod and the connecting part 18 have a certain degree of stability, requiring a large impact force to separate the two.

[0055] Specifically, the connection between the third connecting structure 183 and the fourth connecting structure 33 is a threaded connection. The third connecting structure 183 is a second internal thread provided on the side wall of the first groove 181, and the fourth connecting structure 33 is a second external thread provided on the outer side wall of the guide rod 3. The second internal thread and the second external thread are engaged. In the second use state, the guide rod 3 is rotated so that it is screwed into the first groove 181. When the end of the guide rod 3 abuts against the bottom wall of the first groove 181, a clear resistance will be felt. At this time, the guide rod 3 is rotated again, and the first thin film layer 14 is punctured by the squeezing force of the guide rod 3 against the bottom wall of the groove, so that the drainage hole 31 is connected to the sealing cavity 17. Medical personnel can inject filling medium into the sealing cavity 17 through the drainage hole 31 of the guide rod 3, so that the two side walls of the sealing cavity 17 can expand. The second thin film layer 16 expands into the cavity 11 inside the probe body 1, which can squeeze the affected part of the human body located in the cavity 11, so that the protruding structure 2 can contact the affected area for treatment.

[0056] Specifically, the probe body 1 is a one-piece structure. The raised structure 2, the first thin film layer 14, and the second thin film layer 16 are made of the same base material. Carbon elements or metal conductive ions are added to the base material of the raised structure 2, making the raised structure 2 a conductive structure. The first thin film layer 14 and the second thin film are insulating structures, without affecting the fusion of the raised structure 2 with the first thin film layer 14 and the second thin film. The conductive layer 15 is encapsulated by injection molding, making the conductive layer 15 also a one-piece structure with the raised structure 2, the first thin film layer 14, and the second thin film layer 16, so that the probe body 1 becomes a fused whole, meeting the medical standards for implantable devices. Specifically, the base material can be PC material, which has good flexibility, allowing the probe body 1 to be folded and rolled up.

[0057] The treatment device can be accessed or connected through the opening of the probe body 1. The treatment device is equipped with a control system that can control the flow rate, temperature and pressure of the filling medium delivered to the treatment probe.

[0058] The treatment probe of this invention controls the depth of insertion by injecting a filling medium, which is simple to operate and does not affect the treatment effect. The injection fluid drives the treatment probe to extend into the body, providing high comfort and making it suitable for long-term treatment scenarios. The treatment probe has good expansion and deformation performance, and is highly adaptable to the patient's body shape, meeting the needs of obese patients or patients with special anatomical structures. The length and size of the probe body 1 can be set according to actual needs to adapt to the physiological structures of different patients (such as differences in vaginal length and width), ensuring treatment effect and avoiding damage.

[0059] The treatment probe of this invention has an integrated structure, which can prevent mucous membrane residue from remaining in the gaps of the probe body, reduce the difficulty of disinfection, reduce the risk of infection, and make it less likely to cause cross-infection.

[0060] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit the scope of protection of the utility model.
