[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] This application provides an ultrasound therapy transducer and an ultrasound therapy device to improve ultrasound energy emission efficiency.

[0037] In the medical field, ultrasound transducers can be used to emit ultrasonic energy to specific parts of the human body for therapeutic purposes. However, existing solutions utilize monolithic spherical piezoelectric devices to emit ultrasonic energy. This means that current ultrasound transducers use monolithic spherical piezoelectric devices for treatment, which are expensive to manufacture and have low efficiency in emitting ultrasonic energy, resulting in inadequate therapeutic effects. To address these issues, this application provides an ultrasound transducer and ultrasound therapy device that utilizes a planar piezoelectric device with a concave front cover to emit ultrasonic waves. This approach is less expensive than using spherical piezoelectric devices and offers higher ultrasonic energy emission efficiency, meeting user needs.

[0038] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0039] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0040] The following describes an ultrasound therapy transducer according to this application. Please refer to... Figure 1One embodiment of an ultrasound therapy transducer according to this application includes: a front cover 1, a housing 2, and a planar piezoelectric device 3;

[0041] The front cover 1 has a concave surface 4 at its transmitting end, and the connecting end of the front cover 1 is fixedly connected to the outer shell 2. The transmitting end of the front cover 1 is used to emit ultrasonic energy, and the connecting end of the front cover 1 is connected to the outer shell 2 to form a whole.

[0042] A planar piezoelectric device 3 is disposed within the cavity formed by the outer shell 2 and the front cover 1, and is fixedly connected to the connecting end of the front cover 1. The planar piezoelectric device 3 is used to vibrate when it receives an input electrical signal, thereby causing the concave surface 4 of the front cover to emit ultrasonic energy. The planar piezoelectric device 3 needs to be electrically connected to an external power source. When treatment is needed on a specific part of the human body, power is applied to cause the planar piezoelectric device 3 to vibrate, thereby causing the concave surface 4 of the front cover to emit ultrasonic energy.

[0043] The working principle of this embodiment will now be explained. When the user needs to perform ultrasound treatment on a specific part of the human body, the power supply is plugged in, and the power supply powers the ultrasound treatment transducer through the wires. The planar piezoelectric device 3 vibrates. Since the planar piezoelectric device 3 is fixedly connected to the front cover 1, the concave surface 4 of the front cover vibrates, thereby emitting ultrasound energy.

[0044] In this embodiment, the planar piezoelectric device 3 in the ultrasonic therapy transducer is planar, not spherical. The transmitting end on the front cover 1 also has a concave front cover concave surface 4. When the ultrasonic therapy transducer is powered on, the planar piezoelectric device 3 vibrates, causing the front cover concave surface 4 to radiate ultrasonic energy. Emitting ultrasonic waves based on the front cover concave surface 4 and the planar piezoelectric device 3 results in lower costs compared to spherical piezoelectric devices, avoiding a significant economic burden. Furthermore, the ultrasonic energy emission efficiency is high, meeting the user's needs.

[0045] In order to achieve more effects with existing low costs, the ultrasound therapy transducer of this application has a variety of implementations, which are not limited here. Five embodiments are described below.

[0046] The existing solutions emit relatively low ultrasonic energy, which does not meet the required standards. To achieve the desired therapeutic effect, the front cover 1 of the ultrasonic therapy transducer can be redesigned to utilize a mechanical push-pull principle to increase the amplitude, thereby increasing the emitted ultrasonic energy. Please refer to [link to relevant documentation]. Figures 2 to 5 Another embodiment of an ultrasound therapy transducer of this application includes: a front cover 1, a housing 2, and a planar piezoelectric device 3.

[0047] The front cover 1 has a concave surface 4 at its transmitting end, and the connecting end of the front cover 1 is fixedly connected to the outer shell 2. The transmitting end of the front cover 1 is used to emit ultrasonic energy, and the connecting end of the front cover 1 is connected to the outer shell 2 to form a whole.

[0048] A planar piezoelectric device 3 is disposed within the cavity formed by the outer shell 2 and the front cover 1, and is fixedly connected to the connecting end of the front cover 1. The planar piezoelectric device 3 vibrates upon receiving an input electrical signal, thereby causing the concave surface 4 of the front cover to emit ultrasonic energy. The planar piezoelectric device 3 needs to be electrically connected to an external power source. When treatment is needed on a specific part of the human body, power is applied to cause the planar piezoelectric device 3 to vibrate, thereby causing the concave surface 4 of the front cover to emit focused ultrasonic energy. The specific shape of the planar piezoelectric device 3 can be circular, annular, or other shapes; no specific limitation is made here. This embodiment uses an annular shape as an example. The material of the planar piezoelectric device 3 can be ceramic or other materials; no specific limitation is made here.

[0049] Specifically, the front cover 1 includes: a first connecting part 11, a second connecting part 12 and a third connecting part 13.

[0050] Both the first connecting part 11 and the third connecting part 13 are arranged in a ring. The first end of the first connecting part 11 serves as the transmitting end of the front cover 1 and is connected to the concave surface 4 of the front cover. The second end of the first connecting part 11 is connected to the first end of the third connecting part 13 via the second connecting part 12. The second end of the third connecting part 13 serves as the connecting end of the front cover 1 and is fixed to the outer shell 2. The third connecting part 13 is fixedly connected to the planar piezoelectric device 3.

[0051] Among them, the concave surface 4 of the front cover is a metal concave surface.

[0052] Specifically, the second connecting part 12 is folded and includes at least one connecting structure.

[0053] If there is only one connecting structure, the first end of the connecting structure is connected to the second end of the first connecting part 11, and the last end of the connecting structure is connected to the first end of the third connecting part 13; or, if there are multiple connecting structures, the multiple connecting structures are connected end to end, the first end of the first connecting structure is connected to the second end of the first connecting part 11, and the last connecting structure is connected to the first end of the third connecting part 13. This embodiment uses the second connecting part 12 including one connecting structure as an example. The connecting structure is an annular body, and the cross-section of the connecting structure can have different shapes, such as S-shaped, oblique, or Z-shaped, etc., which are not specifically limited here; this embodiment uses an S-shaped shape as an example.

[0054] In addition, to achieve better sealing and make the ultrasound therapy transducer more robust, a sealing ring 5 can be installed. For example... Figure 3 A sealing ring 5 is provided at the connection between the rear end of the front cover 1 and the outer shell 2. The sealing ring 5 can be an O-ring or other type, which is not limited here.

[0055] The working principle of this embodiment will now be explained. When it is necessary to use an ultrasonic therapy transducer to treat a specific part of the human body, the power supply of the ultrasonic therapy transducer is turned on. The power supply provides high-frequency oscillating current to the planar piezoelectric device 3. Since the planar piezoelectric device 3 has the inverse piezoelectric effect, the changing electrical signal will cause the planar piezoelectric device 3 to deform and vibrate. Due to the mechanical push-pull principle, the foldable front cover 1 can amplify the amplitude of the vibration generated by the planar piezoelectric device 3. Then, the amplified ultrasonic energy is emitted to the specific part of the human body through the concave surface 4 of the front cover, converting electrical energy into mechanical energy to achieve treatment.

[0056] In this embodiment, the foldable front cover 1 is used to amplify the vibration amplitude. Since the amplitude is proportional to the ultrasonic energy, when the amplitude is amplified, the ultrasonic energy emitted to a specific part of the human body will also be amplified accordingly to achieve the therapeutic purpose.

[0057] To achieve a larger amplitude and thus better therapeutic effects, improvements can be made to the above embodiments. Figures 6 to 8 The corresponding embodiments and Figures 2 to 5 The corresponding embodiments are structurally similar, the difference being that... Figures 2 to 5 In the corresponding embodiment, the concave surface 4 of the front cover is a metal concave surface, while Figures 6 to 8 In the corresponding embodiment, the concave surface 4 of the front cover is at least one concave piezoelectric device. The concave surface 4 of the front cover can be one or more concave piezoelectric devices; this is not limited here, but for ease of description, a single concave piezoelectric device will be used for illustration. Please refer to [link to relevant documentation]. Figures 6 to 8 In another embodiment of the ultrasonic therapy transducer of this application, the concave surface 4 of the front cover is a concave piezoelectric device, which is fixedly connected to the first connecting portion 11 of the front cover 1. Other structural features of the ultrasonic therapy transducer in this embodiment are as follows: Figures 2 to 5 The specific details of the corresponding embodiments will not be repeated here.

[0058] The working principle of this embodiment will now be explained. Specifically, before use, the parameters of the foldable front cover 1 need to be adjusted, such as adjusting the thickness, height, width, material, or number of connecting structures, so that the vibration phase difference between the planar piezoelectric device 3 and the concave piezoelectric device is 2nπ (n=1,2,3……) when the ultrasound therapy transducer is working. When the user turns on the power, the planar piezoelectric device 3 deforms and vibrates. Since the vibration phase difference between the planar piezoelectric device 3 and the concave piezoelectric device is 2nπ, their amplitudes are superimposed in the same direction. Based on the structure of the foldable front cover 1, a larger amplitude can be generated by superposition. Please refer to [link to relevant documentation]. Figure 8 Two small amplitudes are superimposed to form a large amplitude, which in turn emits higher ultrasound energy to achieve treatment.

[0059] In this embodiment, the relevant parameters of the front cover 1 structure are adjusted so that the amplitudes of the two piezoelectric devices can be superimposed in the same direction to generate a larger amplitude, thereby emitting higher ultrasonic energy to achieve the therapeutic purpose.

[0060] To adapt to small-space scenarios and save manufacturing costs, the front cover 1 can be designed simply. Please refer to... Figures 9 to 10 Another embodiment of an ultrasound therapy transducer according to this application includes: a front cover 1, a housing 2, and a planar piezoelectric device 3;

[0061] The front cover 1 has a concave surface 4 at its transmitting end, and the connecting end of the front cover 1 is fixedly connected to the outer shell 2. The transmitting end of the front cover 1 is used to emit ultrasonic energy, and the connecting end of the front cover 1 is connected to the outer shell 2 to form a whole.

[0062] A planar piezoelectric device 3 is disposed within the cavity formed by the outer shell 2 and the front cover 1, and is fixedly connected to the connecting end of the front cover 1. The planar piezoelectric device 3 vibrates upon receiving an input electrical signal, thereby causing the concave surface 4 of the front cover to emit ultrasonic energy. The planar piezoelectric device 3 needs to be electrically connected to an external power source. When treatment is required on a specific part of the human body, power is applied to cause the planar piezoelectric device 3 to vibrate, thereby causing the concave surface 4 of the front cover to emit ultrasonic energy. The specific shape of the planar piezoelectric device 3 can be circular, annular, or other shapes; no specific limitation is made here. This embodiment uses an annular shape as an example. The material of the planar piezoelectric device 3 can be ceramic or other materials; no specific limitation is made here.

[0063] Specifically, the concave surface 4 of the front cover is a metal concave surface. The back of the concave surface 4 serves as the connecting end of the front cover 1 and is fixedly connected to the planar piezoelectric device 3. The thickness of the concave surface 4 is an integer multiple of half the wavelength of the sound wave generated by vibration. In particular, the thickness of the concave surface 4 is an integer multiple of half the center wavelength to maintain the same resonant frequency as the planar piezoelectric device 3.

[0064] In addition, to achieve better sealing and make the ultrasound therapy transducer more robust, a sealing ring 5 can be installed. A sealing ring 5 is installed at the connection between the rear end of the front cover 1 and the outer shell 2. The type of sealing ring 5 can be O-ring or other types; specific details are not limited here.

[0065] The working principle of this embodiment will now be explained. When the user turns on the power supply of the ultrasonic therapy transducer, the ultrasonic therapy transducer works, that is, the planar piezoelectric device 3 is energized and deforms, vibrating. The back of the concave surface 4 of the front cover is directly connected to the planar piezoelectric device 3, so it can also vibrate and emit ultrasonic energy for treatment.

[0066] In this embodiment, ultrasonic energy can be emitted without a large front cover 1 to achieve the therapeutic effect. Such an ultrasonic therapy transducer occupies little space, and the manufacturing cost of the smaller front cover 1 is lower, reducing the economic burden and providing users with a better experience.

[0067] To increase the amplitude and thus the emitted ultrasound energy to meet therapeutic requirements, it is possible to... Figures 9 to 10 At least one concave piezoelectric device 6 is added to the structure of the corresponding embodiment. That is... Figures 11 to 12 The corresponding embodiments are the same as those described above. Figures 9 to 10 The corresponding embodiments are structurally similar, the difference being that... Figures 11 to 12 In the embodiments described, multiple concave piezoelectric devices 6 are provided. The number of concave piezoelectric devices 6 provided can be one or more, and is not limited here. For ease of description, one concave piezoelectric device 6 will be used for illustration. Please refer to... Figures 11 to 12 In another embodiment of an ultrasound therapy transducer according to this application, a concave piezoelectric device 6 is disposed on the concave surface 4 of the front cover. The concave piezoelectric device 6 is disposed close to the concave surface 4 of the front cover. Other structural features of the ultrasound therapy transducer in this embodiment are as follows. Figures 9 to 10 The specific details of the corresponding embodiments will not be repeated here.

[0068] The working principle of this embodiment will now be explained. When the user turns on the power supply of the ultrasound therapy transducer, the ultrasound therapy transducer works, that is, the planar piezoelectric device 3 is energized and deforms, vibrating. The back of the concave surface 4 of the front cover is directly connected to the planar piezoelectric device 3, and the concave piezoelectric device 6 is fixedly connected to the concave surface 4 of the front cover. Therefore, the concave piezoelectric device 6 can also vibrate. The superposition of the amplitudes of the two piezoelectric devices increases the emitted ultrasound energy for treatment.

[0069] In this embodiment, both the planar piezoelectric device 3 and the concave piezoelectric device 6 can vibrate, and their amplitudes can be superimposed to form a larger amplitude, thereby emitting higher ultrasonic energy to act on specific parts of the human body to achieve the therapeutic purpose.

[0070] To increase the amplitude and thus the emitted ultrasound energy to meet therapeutic requirements, it is possible to... Figures 9 to 10 The corresponding embodiment is further equipped with a back cover 7 and an insulating sheet 8. That is... Figures 13 to 14 The corresponding embodiments are the same as those described above. Figures 9 to 10 The corresponding embodiments are structurally similar, the difference being that... Figures 13 to 14 In some embodiments, a back cover 7 and an insulating sheet 8 are provided. Please refer to [link / reference]. Figures 13 to 14Another embodiment of an ultrasonic therapy transducer according to this application further includes: a rear cover 7 and an insulating sheet 8; the insulating sheet 8 is tightly attached to the planar piezoelectric device 3, and the rear cover 7 is fixed to the insulating sheet 8. Specifically, the rear cover 7 can be fixedly connected to other devices by screws or glue, etc., and this embodiment uses screws as an example. The material of the rear cover 7 can be a high-density material or a non-metallic material, and is not limited here. The insulating sheet 8 is used to prevent the piezoelectric device from short-circuiting and failing to work properly. Other structures of the ultrasonic therapy transducer in this embodiment are referenced. Figures 9 to 10 The specific details of the corresponding embodiments will not be repeated here.

[0071] The working principle of this embodiment will now be explained. When in use, a material with a higher density can be selected as the back cover 7. When the power is turned on, the planar piezoelectric device 3 is energized, causing deformation and vibration. Due to the principle of conservation of momentum, the greater the mass of the back cover 7, the greater the amplitude of the vibration, which in turn results in greater ultrasonic energy emitted from the concave surface 4 of the front cover.

[0072] In this embodiment, by fixing the rear cover 7 and the insulating sheet 8 onto the planar piezoelectric device 3, the rear cover 7 has a larger mass and is relatively fixed to the planar piezoelectric device 3 when the planar piezoelectric device 3 vibrates due to deformation. Therefore, the front cover 1 obtains a larger amplitude and thus obtains higher ultrasonic energy to achieve the therapeutic purpose.

The following describes an ultrasound therapy device according to an embodiment of this application. One embodiment of the ultrasound therapy device according to an embodiment of this application includes the ultrasound therapy transducer described above.
