[0005] Based on this, the inventors improved the efficiency of sound wave energy transmission of the ultrasonic therapy probe, removed the water circulation structure, and on this basis, further precisely designed the sealing performance inside the ultrasonic therapy probe to reduce the risk of bubble generation, thereby solving the technical defects described in the background technology.

[0054] <First aspect: Ultrasonic therapy probe>

[0055] like Figures 1 to 17 As shown, the first aspect provides an ultrasonic treatment probe 10.

[0056] Figure 1 is a schematic diagram of an exploded structure of the ultrasonic treatment probe 10 in some embodiments, Figure 2 for Figure 1 An overall schematic diagram of the ultrasonic treatment probe 10 after the various structures are connected together, Figure 3 for Figure 2 A schematic diagram of the structure of the ultrasonic treatment probe 10 after cutting; Figures 1 to 3 As shown, the ultrasonic therapeutic probe 10 includes: a sound-conducting device 200 and an acoustic device 100, wherein the acoustic device 100 includes a first acoustic device 110 and a second acoustic device 120, the sound-conducting device 200 includes a liquid box 210 containing a sound-conducting liquid, and the first acoustic device 110, the second acoustic device 120 and the liquid box 210 are connected in sequence.

[0057] The schematic diagram of the first acoustic device 110, the second acoustic device 120 and the liquid box 210 being connected in sequence can be seen in Figure 4 shown.

[0058] like Figure 5 As shown, the liquid box 210 can be prepared with flexible materials such as leather bags and silicone. At the same time, when preparing the liquid box 210, it is necessary to pay attention to the compatibility of the material with the organism to avoid the risk of infection to the skin tissue of the organism (such as the human body). The liquid box 210 contains a sound-conducting liquid for transmitting sound waves, which can be realized by substances such as oil and water. However, in the process of treating the human body, water is usually selected as the sound-conducting liquid because the acoustic impedance of water is close to the acoustic impedance of human blood, which can enhance the therapeutic effect of ultrasound. As for how the liquid box 210 contains the sound-conducting liquid, those skilled in the art can implement it according to the prior art, for example, a chamber is set in the liquid box 210, and the sound-conducting liquid is placed in the chamber.

[0059] Continue to see Figure 6 , Figure 6is a schematic diagram of the entirety of the first acoustic device 110 and the second acoustic device 120 after being connected. Figure 6 Based on the combination Figure 7 As shown, it can be known that the first acoustic device 110 includes a sound-transmitting surface 111, and the first acoustic device 110 is used to convert electrical energy into sound waves in the form of acoustic energy and emit the sound waves through the sound-transmitting surface 111. The first acoustic device 110 can be implemented by an existing sound wave transducer, which includes piezoelectric ceramics, and converts electrical energy into sound waves in the form of acoustic energy through the piezoelectric ceramics for transmission. A person skilled in the art can relatively easily implement a specific design scheme based on common knowledge.

[0060] Continue as Figure 8 , Fig. 9 As shown, the second acoustic device 120 includes a sound input surface 121 and a sound output surface 122, and further combines Figure 6 As shown, it is easy to know that the sound input surface 121 covers the sound transmission surface 111, and the second acoustic device 120 receives the sound wave through the sound input surface 121, and then transmits the sound wave to the sound output surface 122, and then emits the sound wave from the sound output surface 122. Among them, the second acoustic device 120 can be implemented by a sound wave matching layer adapted to the aforementioned piezoelectric ceramic, and here, the sound wave matching layer can also be implemented by the existing technology.

[0061] Among them, the acoustic impedance of the second acoustic device 120 is smaller than the acoustic impedance of the first acoustic device 110, and at the same time greater than the acoustic impedance of the sound-conducting liquid. More specifically, the acoustic impedance of the second acoustic device 120 is designed according to the acoustic impedances of the first acoustic device 110 and the sound-conducting liquid. When the acoustic impedance value of the second acoustic device 120 is equal to the square root of the product of the acoustic impedance value of the first acoustic device 110 and the acoustic impedance value of the sound-conducting liquid, the energy transfer efficiency of the ultrasonic wave is the highest.

[0062] On the basis of the above, the liquid box 210 is sealed and connected to the second acoustic device 120, so that the sound-conducting liquid contained in the liquid box 210 is in sealed contact with the sound-emitting surface 122, so as to transmit the sound waves from the sound-emitting surface 122 to the sound-conducting liquid.

[0063] During actual use, after the ultrasonic wave is generated from the first acoustic device 110, it passes through the sound-transmitting surface 111, the sound input surface 121 of the second acoustic device 120, the sound output surface 122, and the sound-conducting liquid in sequence, and is finally transmitted through the liquid box 210 to the receptor to be treated (the receptor can be a human body, an animal body, etc.).

[0064] In the above embodiment, the purpose of sealingly connecting the liquid box 210 and the second acoustic device 120 so that the sound-conducting liquid is in sealed contact with the sound-emitting surface 122 is to prevent air from entering the sound-conducting liquid and affecting the efficiency of sound wave transmission in the sound-conducting liquid. More importantly, it is to prevent air from forming bubbles in the sound-conducting liquid, because bubbles will hinder the sound waves from passing through the sound-conducting liquid and the liquid box 210 to enter the treated receptor. At the same time, the energy generated by the sound waves is blocked in the liquid box 210, which will greatly increase the temperature of the liquid box 210. When the temperature reaches a certain level, the risk of scalding the receptor will inevitably increase, because the receptor is generally the surface skin or tissue organs of the human body, etc., especially when treating the sexual function of the male reproductive organ, this risk will undoubtedly bring greater harm.

[0065] Compared with the prior art, the ultrasonic treatment probe 10 provided in the first aspect adds the second acoustic device 120 suitable for sound wave transmission between the first acoustic device 110 and the second acoustic device 120, thereby improving the energy transmission efficiency of the sound wave from the first acoustic device 110 to the sound-conducting liquid, thereby removing the water circulation structure in the traditional probe. The above improvement can at least bring the following technical effects: First, due to the removal of the water circulation structure, the probe structure design can be simplified and the processing cost can be reduced; second, due to the removal of the water circulation structure, the sealing performance inside the probe can be better improved, and bubbles can be avoided in the sound-conducting liquid to affect the transmission of sound energy. The main principle is that: the water circulation structure is mixed with water pipes, water pumps and other devices, resulting in the need to add connecting pipe openings between the aforementioned devices and between the aforementioned water circulation structure and other structures inside the probe, which will inevitably reduce the overall sealing performance of the probe.

[0066] Further, continue as Figure 1 , Figure 4 , Figure 5 As shown, in some embodiments, the liquid box 210 is provided with a first communication hole 211 at the sealed connection with the second acoustic device 120, and the second acoustic device 120 is accommodated in the first communication hole 211 and is sealedly connected with the first communication hole 211, so that the sound-conducting liquid in the liquid box 210 can be sealed and contacted with the sound output surface 122 through the first communication hole 211. As for the specific manner of the sealed connection between the second acoustic device 120 and the first communication hole 211, please continue to refer to the specific embodiments described below. Of course, in some other embodiments, ordinary personnel in the field of technology can also implement it according to common knowledge.

[0067] Furthermore, in some embodiments, the areas of the sound-transmitting surface 111 and the second communication hole 221 are substantially equal. This solution can maximize the transmission of the acoustic energy in the first acoustic device 110 to the sound-conducting liquid, avoiding waste of structural design space.

[0068] Further, based on the above, Figure 1 , Figure 3 , Fig.10 , Fig.11 As shown, in some embodiments, the sound-conducting device 200 also includes a fixing frame 220 sealed and connected to the first connecting hole 211, wherein the fixing frame 220 has a second connecting hole 221 connected to the first connecting hole 211, the second connecting hole 221 is accommodated in the first connecting hole 211, and the second acoustic device 120 is sealed and connected to the second connecting hole 221.

[0069] Specifically, the fixing frame 220 is set in an annular shape, and a connecting portion 226 is provided on the fixing frame 220. The connecting portion 226 extends from the first connecting hole 211 into the interior of the liquid box 210, and is in a sealing connection with the inner wall of the liquid box 210 (the schematic diagram of the sealing connection between the liquid box 210 and the fixing frame 220 can be seen in Fig.12 As shown), of course, a person skilled in the art may also achieve a sealed connection between the fixing frame 220 and the liquid box 210 in other ways. For example, in some embodiments, a wrapping portion (not shown in the figure) may be provided on the fixing frame 220, and the wrapping portion wraps the end of the liquid box 210 where the first connecting hole 211 is provided.

[0070] On the basis of the above, the annular fixing frame 220 is provided with a second connecting hole 221 in a portion corresponding to the first connecting hole 211, the second connecting hole 221 is consistent with the through direction of the first connecting hole 211 and is accommodated in the first connecting hole 211, and then the second acoustic device 120 is sealed and connected to the second connecting hole 221; Fig.13 As shown, one specific sealing method is to cover the sound-emitting surface 122 of the second acoustic device 120 on the second connecting hole 221. In this way, the first connecting hole 211 can be sealed together with the second acoustic device 120 and the fixing frame 220 to prevent air from entering the sound-conducting liquid. Of course, ordinary technicians in this field can also design other sealing schemes based on the aforementioned invention concepts.

[0071] It should be noted that the design of the fixing frame 220 can bring at least two technical effects. One of the effects is to improve the stability of the liquid box 210, so as to facilitate the sealed connection between the second acoustic device 120 and the first connecting hole 211; as mentioned above, the liquid box 210 is usually made of a flexible material, which is not easy to operate in the connection with the second acoustic device 120. After the rigid fixing frame 220 is sealed and set on the liquid box 210, the sealed connection between the second acoustic device 120 and the first connecting hole 211 can be achieved relatively easily.

[0072] In addition, the shape of the flexible liquid box 210 is easily changed significantly under the gravity of the sound-conducting liquid and the impact of sound waves, affecting the sealing performance between the second acoustic device 120 and the first communication hole 211, and causing operational difficulties in the use of the ultrasonic treatment probe 10. In the above solution, these problems are easily solved by introducing the rigid fixing frame 220.

[0073] Further, continue to combine Figure 3 , Figure 5 , Figure 10-13 As shown, at the contacting point between the fixing frame 220 and the inner wall of the liquid box 210, a first connection hole 212 is provided on the wall of the liquid box 210, and a first connection column 223 matching the first connection hole 212 is provided on the fixing frame 220. The first connection column 223 is inserted into the first connection hole 212 and passes from the inside of the liquid box 210 to the outside of the liquid box 210. This solution improves the firmness of the connection between the fixing frame 220 and the liquid box 210.

[0074] Furthermore, at the contact point between the fixing frame 220 and the inner wall of the liquid box 210, a second connecting hole 213 is also provided on the wall of the liquid box 210, and a second connecting column 224 is provided on the fixing frame 220. When the connecting portion 226 of the fixing frame 220 extends into the liquid box 210, the second connecting column 224 is located in the internal space of the liquid box 210, and a first connecting channel 2241 is provided in the second connecting column 224. When the liquid box 210 and the fixing frame 220 are connected together, the first connecting channel 2241 is communicated with the second connecting hole 213.

[0075] In addition, at the contacting point between the fixing frame 220 and the inner wall of the liquid box 210, a third communication hole 214 is further provided on the wall of the liquid box 210, and a fourth communication hole 225 communicating with the third communication hole 214 is provided on the fixing frame 220. The third communication hole 214 and the fourth communication hole 225 are used for exhausting and introducing liquid into the liquid box 210.

[0076] Furthermore, if Fig.10 As shown, in some embodiments, a groove 222 is provided in the fixing frame 220, and the opening direction of the groove 222 is away from the sound-conducting liquid, and the second connecting hole 221 is provided at the bottom of the groove 222, wherein the sound output surface 122 is accommodated in the groove 222 and is in contact with the bottom surface of the groove 222, and blocks the second connecting hole 221.

[0077] In this embodiment, the groove 222 structure can more conveniently connect the second acoustic device 120 to the annular fixing frame 220, and the second connecting hole 221 is arranged at the bottom of the groove 222, so that the second acoustic device 120 can better block the second connecting hole 221, thereby completing the sealed contact between the second acoustic device 120 and the sound-conducting liquid (the schematic diagram of the sound-emitting surface 122 accommodated in the groove 222 can be referred to Fig.13 ).

[0078] Furthermore, if Figure 14-16 As shown, in some embodiments, the ultrasonic treatment probe 10 further includes a seal 300, which is disposed in a gap (not shown in the figure) formed between the second acoustic device 120 and the groove 222 to seal the gap.

[0079] Because a gap is inevitably generated when the second acoustic device 120 is combined with the groove 222, in this case, the sealing member 300 is provided to seal the gap formed between the second acoustic device 120 and the groove 222, which can undoubtedly improve the sealing performance of the liquid box 210. The sealing member 300 can be made of a flexible material, such as rubber products, animal leather, silk fabrics, etc.

[0080] Further, continue to combine Figure 1 , Figure 3 , Fig.14 , Fig.15 As shown, in some embodiments, the seal 300 is configured to be annular in shape matching the shape of the second acoustic device 120 , an annular channel matching the shape of the second acoustic device 120 is configured inside the seal 300 , and the seal 300 is sleeved on the second acoustic device 120 .

[0081] Furthermore, the sound entrance surface 121 on the second acoustic device 120 is larger than the sound transmission surface 111 on the first acoustic device 110. In fact, when the sound entrance surface 121 is arranged on the sound transmission surface 111, the portion of the sound entrance surface 121 that is not in direct contact with the sound transmission surface 111 corresponds to a clamping portion 123 on the second acoustic device 120 (the clamping portion 123 can be seen in FIG. Figure 6 Correspondingly, the inner side wall of the annular channel of the sealing member 300 is recessed in a direction away from the center of the ring to form a slot 301 matching the clamping portion 123, and the second acoustic device 120 is clamped in the slot 301 through the clamping portion 123, see Fig.15 shown.

[0082] The technical solution in the above embodiment can bring at least two technical effects: first, when the second acoustic device 120 is combined with the groove 222, it is difficult for the sound-emitting surface 122 to have zero distance contact with the inner wall of the groove 222, and there will always be a little gap, so wrapping the flexible seal 300 on the second acoustic device 120 can further improve the sealing performance. During the transmission process, the sound wave will cause the vibration of the first acoustic device 110 and the second acoustic device 120, thereby affecting the sealing of the connection between the second acoustic device 120 and the liquid box 210; and the above solution can stably fix the second acoustic device 120 in the groove 222 through the clamping between the clamping groove 301 and the clamping part 123, thereby further improving the sealing of the second acoustic device 120 and the second connecting hole 221 after the connection.

[0083] Further, based on the previous article, Figure 1 , Figure 2 , Fig.16 As shown, in some embodiments, the ultrasonic treatment probe 10 further includes a housing 400 sealed with the liquid box 210, and the first acoustic device 110 and the second acoustic device 120 are disposed inside the housing 400. A vacuum environment can be provided for the first acoustic device 110 and the second acoustic device 120 to prevent air from entering the liquid box 210 from the connection between the second acoustic device 120 and the groove 222, thereby further improving the sealing performance, and also preventing the sound waves in the first acoustic device 110 from being transmitted to the air, thereby reducing the efficiency of sound energy transmission.

[0084] The housing 400 is provided with a connection groove 401 matching the liquid box 210, and the connection groove 401 is sleeved on the end of the liquid box 210 that is sealed and connected to the second acoustic device 120. Specifically, the end (not shown in the figure) of the liquid box 210 where the first communication hole 211 is provided is accommodated in the connection groove 401, and the aforementioned end is sealed and connected to the inner wall of the connection groove 401.

[0085] Furthermore, the shell 400 is provided with a third connecting hole 405 matching the first connecting column 223 in the connecting groove 401, and a reinforcing portion 408 is provided on the back side of the outside of the shell 400 corresponding to the third connecting hole 405. When the shell 400, the fixing frame 220, and the liquid box 210 are connected together, the first connecting column 223 passes through the first connecting hole 212 from the inside of the liquid box 210 to the outside of the liquid box 210, and is further inserted into the third connecting hole 405.

[0086] In addition, a fourth connection hole 406 is provided on the shell 400 at a position corresponding to the second connection column 224. When the shell 400, the fixing frame 220, and the liquid box 210 are connected together, the fourth connection hole 406 is connected with the second connection hole 213 and the first connection channel 2241 in the second connection column 224 in sequence. In some embodiments, a thread can be provided in the first connection channel 2241, and then a screw is inserted from the outside of the shell 400 into the fourth connection hole 406, the second connection hole 213, and the first connection channel 2241 in the second connection column 224, and the screw is screwed with the thread provided in the first connection channel 2241. Thus, the shell 400, the fixing frame 220, and the liquid box 210 are tightly connected together. Of course, in other embodiments, ordinary technicians in this field can also perform other forms of sealing connection between the shell 400 and the liquid box 210 according to actual needs.

[0087] Furthermore, the shell 400 is provided with a receiving groove 402 at the bottom of the connecting groove 401 for accommodating the second acoustic device 120 , and the shell 400 is provided with a receiving cavity 403 at the bottom of the connecting groove 401 for accommodating the first acoustic device 110 .

[0088] Among them, the receiving groove 402 matches the shape of the second acoustic device 120. When the shell 400 is connected to the fixing frame 220, the groove 222 and the receiving groove 402 clamp the second acoustic device 120 therein. The second acoustic device 120 is fixed more stably to prevent the vibration caused by the sound waves from affecting the sealed connection between the second acoustic device 120 and the sound-conducting liquid. Similarly, the receiving cavity 403 also matches the shape of the first acoustic device 110, which facilitates the fixing of the first acoustic device 110. In addition, the receiving cavity 403 is connected to the bottom of the receiving groove 402. During installation, the first acoustic device 110 passes through the receiving groove 402 and enters the receiving cavity 403.

[0089] Furthermore, the notch of the accommodating groove 402 is completely consistent with the notch of the groove 222, and the two are connected to form a closed space, which completely seals the second acoustic device 120 therein, which can directly improve the sealing effect and fix the second acoustic device 120 more firmly.

[0090] Further, a connecting rod 112 is provided at the bottom of the second acoustic device 120, and the connecting rod 112 passes through the bottom of the accommodating cavity 403 and communicates with the external space of the shell 400. A second connecting channel 1121 is provided in the end of the connecting rod 112 facing the outside of the shell 400 for connecting with other devices, and the shell 400 is provided with a sixth connecting hole 409 matching the second connecting channel 1121 at the bottom of the accommodating cavity 403, and the second connecting channel 1121 is communicated with the sixth connecting hole 409.

[0091] Furthermore, the bottom of the accommodating cavity 403 extends toward the direction of the first acoustic device 110 to form a plurality of fixing columns 404, one end of the fixing column 404 is in contact with the bottom of the accommodating cavity 403, and the other end is in contact with the first acoustic device 110, and the axial direction of the fixing column 404 is substantially parallel to the axial direction of the connecting rod 112. This solution is mainly used to stabilize the first acoustic device 110 in the accommodating cavity 403 to prevent the first acoustic device 110 from affecting the sealed connection between the second acoustic device 120 and the sound-conducting liquid under the vibration caused by the sound wave.

[0092] Furthermore, the housing 400 is also provided with a water inlet and an exhaust hole, the water inlet and the exhaust hole are respectively connected to the sound-conducting liquid space inside the liquid box 210; and a sealing valve for opening and closing the exhaust hole and the water inlet. The sealing valve can be made of soft rubber material, such as a rubber seal.

[0093] The implementation method of the water inlet hole and the exhaust hole can be as follows: at least two fifth connecting holes 407 are set on the shell 400, at least one of the at least two fifth connecting holes 407 is set as the water inlet hole, and at least one is set as the exhaust hole, and each of the fifth connecting holes 407 is connected in sequence with a matching third connecting hole 214 and a fourth connecting hole 225, thereby realizing the water inlet and exhaust functions.

[0094] Furthermore, a threaded member 500 is provided on the outer wall of the housing 400 for connection with other devices.

[0095] Furthermore, a sealing ring 600 is provided on the housing 400. Since the housing 400 is usually required to be connected to other devices, such as a host controlling the ultrasonic treatment probe 10, a sealing ring 600 is required to prevent water from entering the connection between the housing 400 and other devices.
