[0038] like Figure 1 A treatment probe shown in Figure 3 includes a probe main housing 100 and a rotating disk 200. The probe main housing 100 and the rotating disk 200 are connected by a rotating shaft 210 perpendicular to the centers of the two circles. The rotating disk 200 rotates relative to the probe main housing 100 around the axis of the rotating shaft 210. A gripping handle 400 is fixedly connected to the side of the probe main housing 100 facing away from the rotating disk 200. Three treatment heads 300 protruding outward are provided on the side of the rotating disk 200 facing away from the probe main housing 100. The three treatment heads 300 are all arranged away from the central axis of the rotating shaft 210.

[0039] In some embodiments, the three treatment heads 300 include at least one ultrasonic treatment head for transmitting and receiving ultrasonic waves and at least one electrode treatment head for conducting current; the three treatment heads 300 are evenly arranged around the same circumference with the rotating shaft 210 as the center. The parts of the ultrasonic treatment head and the electrode treatment head protruding outward from the surface of the rotating disk 200 are both provided with flexible structures. During the use of this ultrasonic treatment probe, the flexible structures on the ultrasonic treatment head and the electrode treatment head are in soft contact with the human body. When the rotating disk 200 rotates, the flexible structures on the ultrasonic treatment head and the electrode treatment head massage the human body, which can improve the comfort during the massage process; at the same time, the ultrasonic treatment head can emit ultrasonic waves to the human body, and ultrasonic rehabilitation treatment can be used while automatically massaging.

In an alternative embodiment, the treatment head 300 can also include a microwave treatment head 300 for emitting microwaves, and the three treatment heads 300 can be treatment heads 300 of the same functional type or different functional types; the number of treatment heads 300 is not limited to three, and can be adaptively adjusted to four, five or other numbers as needed.

[0040] In some embodiments, the probe main housing 100 and the rotating disk 200 are both in the shape of an oblate cylinder and have the same diameter, the circular surface of the probe main housing 100 is parallel to the circular surface of the rotating disk 200, and there is a gap between the circular surface of the probe main housing 100 and the circular surface of the rotating disk 200. An axial support is connected to the probe main housing 100, and the axial support rolls with the surface of the rotating disk 200 facing the probe main housing 100, and the axial support is suitable for providing a support force for the rotating disk 200 along the radial direction of the rotating shaft 210. In other alternative embodiments, the axial support can also be provided on the rotating disk 200, and the axial support rolls with the surface of the probe main housing 100 facing the rotating disk 200.

[0041] This therapeutic probe is configured by additionally providing an axial support at the gap between the probe main shell 100 and the rotating disk 200, and the axial support is in rolling cooperation with the rotating disk 200 or the surface of the probe main shell 100 facing the gap; when the outer end of the rotating disk 200 with a larger diameter is subjected to a greater axial pressure, the axial support can provide additional axial support for the portion of the rotating disk 200 outside the rotation center, so that the force at each position of the rotating disk 200 is more uniform, and the rotating shaft 210 is prevented from being subjected to excessive lever force, so that the rotating shaft 210 is not easily worn or damaged, which is beneficial to reducing the shaking of the rotating disk 200 during rotation; and the rolling support method can reduce friction resistance and noise.

[0042] In some embodiments, the axial support member is specifically a roller 500 connected to the probe main housing 100, the roller 500 is rotatable around its own axis, at least a portion of the roller 500 is exposed from the surface of the probe main housing 100 facing the rotating disk 200, and the outer circle of the roller 500 is rollingly matched with the surface of the rotating disk 200 facing the probe main housing 100. The use of the roller 500 as the axial support member has the advantages of simple structure and low manufacturing cost. In other alternative embodiments, the axial support member can also be a ball embedded in the concave cavity of the probe main housing 100 and can rotate freely, or a plane bearing or a plane circular slip ring arranged in the gap between the probe main housing 100 and the rotating disk 200.

[0043] In some embodiments, the roller 500 may be made of metal or plastic, and the axis direction of the roller 500 itself is perpendicular to the axis direction of the rotating shaft 210. There are multiple rollers 500, and the multiple rollers 500 are arranged on concentric circles with the rotating shaft 210 as the center. Such an arrangement can make the rotating disk 200 evenly stressed, which is conducive to improving the stability of the rotating disk 200 during rotation.

[0044] In some embodiments, the roller 500 is supported at a position close to the outer edge of the rotating disk 200. When the outer end of the rotating disk 200 is subjected to axial pressure, the force arm between the roller 500 support and the rotating shaft 210 is longer, and the corresponding lever force on the rotating shaft 210 is smaller, and the rotating shaft 210 is less likely to wear.

[0045] In some embodiments, the surface of the rotating disk 200 facing the probe main housing 100 is provided with a circular track groove 220, and the track groove 220 and the roller 500 are located on a concentric circle with the rotating shaft 210 as the center. The track groove 220 guides the movement direction of the roller 500, so that the friction resistance encountered by the rotating disk 200 when rotating is smaller. Furthermore, the bottom of the track groove 220 is provided with a wear-resistant part 600, and the wear-resistant part 600 can reduce the wear between the roller 500 and the rotating disk 200, and prevent the rotating disk 200 from being easily shaken due to excessive wear of the roller 500 after long-term use. The wear-resistant part 600 is specifically a metal part (stainless steel, brass, etc.) or a plastic part (polytetrafluoroethylene, nylon, POM, PEEK, etc.).

[0046] In some embodiments, a motor and a transmission assembly connected between the motor and the rotating shaft 210 are provided in the probe main housing 100, and the motor drives the rotating disk 200 to rotate relative to the probe main housing 100 around the axis of the rotating shaft 210 through the transmission assembly. The motor drives the rotating disk 200 to rotate through the transmission assembly, so that the treatment heads 300 on the rotating disk 200 can treat the human body in turn. At the same time, the treatment heads 300 of the rotating disk 200 can use electric current, ultrasound or microwaves to perform rehabilitation treatment on the human body, thereby improving the function of the treatment probe.

[0047] In some embodiments, the rotating shaft 210 is a cylindrical body fixedly connected to the rotating disk 200 and protruding toward the probe main housing 100, the transmission assembly includes a final gear 120 arranged corresponding to the position of the rotating shaft 210, and the end surface of the final gear 120 facing the rotating shaft 210 is provided with a plurality of mounting grooves 121 arranged offset from the center of the final gear 120, and the rotating disk 200 is provided with a connecting column 230 located inside the rotating shaft 210, and the connecting column 230 is fixed on the mounting groove 121. By setting the rotating shaft 210 as a cylindrical body, the support area provided by the rotating shaft 210 for the rotating disk 200 can be increased as much as possible, which is conducive to improving the stability of the rotating disk 200 during rotation.

[0048] In some embodiments, the end of the rotating shaft 210 facing the final gear 120 is provided with a plurality of notched grooves 211, and the end surface of the final gear 120 facing the rotating shaft 210 is provided with a plurality of limiting strips 122, and the limiting strips 122 extend into the notched grooves 211 corresponding to the positions. The rotating shaft 210 and the final gear 120 cooperate with each other through the notched grooves 211 and the limiting strips 122, so that the transmission stability between the final gear 120 and the rotating shaft 210 can be improved.

[0049] In some embodiments, a main control circuit board 110 is provided in the probe main housing 100, a central through hole 123 is provided in the middle of the final gear 120, a wire post 240 is provided in the center of the rotating shaft 210, a wire channel is provided in the wire post 240, a conductive slip ring 130 is inserted in the central through hole 123 of the final gear 120, one end of the conductive slip ring 130 extends into the probe main housing 100 to be electrically connected to the main control circuit board 110, and the other end passes through the wire channel of the wire post 240 to be electrically connected to a plurality of treatment heads 300 in the rotating disk 200. In this way, the circuit connection between the treatment head 300 and the main control circuit board 110 can be realized, and the treatment head 300 is controlled by the main control circuit board 110 to perform corresponding functions, so as to achieve the effect of automatic treatment. In addition, the structural design of the conductive slip ring 130 passing through the final gear 120 and the rotating shaft 210 is not only conducive to realizing a compact design, but also can avoid the phenomenon of internal wires being entangled when the rotating disk 200 rotates, thereby improving the reliability of the product.

[0050] In summary, the therapeutic probe provided by the utility model is provided with an additional roller 500 at the gap between the probe main shell 100 and the rotating disk 200, and the roller 500 and the surface of the rotating disk 200 facing the gap are rollingly matched; when the outer end of the rotating disk 200 with a larger diameter is subjected to a larger axial pressure, the roller 500 can provide additional axial support for the part of the rotating disk 200 outside the rotation center, so that the force at each position of the rotating disk 200 is more uniform, and the rotating shaft 210 is prevented from being subjected to excessive lever force, so that the rotating shaft 210 is not easily worn or damaged, which is beneficial to reduce the shaking of the rotating disk 200 during rotation; and the rolling support method can reduce friction resistance and noise.

[0051] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
