Technical Field

[0001] The utility model relates to the technical field of ultrasonic, and specifically, to a focused ultrasonic treatment head, an operating handle provided with the focused ultrasonic treatment head, and an ultrasonic beauty instrument provided with the operating handle. Background Art

[0002] At present, the treatment heads of the ultrasonic scalpels or ultrasonic guns used in the medical aesthetics industry are both equipped with focused ultrasonic transducers. However, since the treatment head has only one fixed focal length output, the depth of penetration into the human body remains at a fixed value. In actual treatment processes, treatments at different depths are often required, such as multi-level treatments for the dermis, superficial fat layer, fascia layer, etc. of the human body. This results in the need to frequently replace the treatment head according to different requirements during the treatment process, making the operation cumbersome, inefficient, and the treatment effect being affected to a certain extent. Summary of the Invention

[0003] The main purpose of the utility model is to provide a focused ultrasonic treatment head that can achieve multiple focal length outputs and has a good treatment effect.

[0004] Another purpose of the utility model is to provide an operating handle provided with the above-mentioned focused ultrasonic treatment head.

[0005] Another purpose of the utility model is to provide an ultrasonic beauty instrument provided with the above-mentioned operating handle.

[0006] To achieve the main purpose of the utility model, the utility model provides a focused ultrasonic treatment head, which includes a housing, a bracket, and a first transducer. The housing has a receiving cavity, and the acting end of the housing has a first opening communicating with the receiving cavity. A membrane is installed at the first opening. The bracket is installed in the receiving cavity, and the first transducer is installed on the bracket and faces the membrane. The first focus of the first transducer is located outside the receiving cavity. Among them, the focused ultrasonic treatment head further includes a second transducer and a third transducer. The second transducer is installed on the bracket and faces the membrane. The second focus of the second transducer is located outside the receiving cavity. The third transducer is installed on the bracket and faces the membrane. The third focus of the third transducer is located outside the receiving cavity. The first transducer is located between the second transducer and the third transducer. The first transducer and the second transducer are distributed at a first angle, and the first transducer and the third transducer are distributed at a second angle. The first transducer, the first focus, the second focus, and the third focus are distributed along the normal direction of the membrane.

[0007] As can be seen from the above, by setting the second transducer and the third transducer and designing the relative positions among the first transducer, the second transducer and the third transducer, the focused ultrasound treatment head can perform operations with three different focal lengths (i.e., action depths), and during the treatment process, there is no need to frequently replace the focused ultrasound treatment head. Only a single focused ultrasound treatment head can perform multi-level treatments on the human dermis, superficial fat layer, fascia layer, etc., which not only improves the convenience of operation, but also can improve efficiency, ensure the treatment effect, and at the same time can reduce the user's usage cost to a certain extent.

[0008] A preferred solution is that in the normal direction, there is a first distance between the first focus and the membrane, a second distance between the second focus and the first focus, and a third distance between the third focus and the second focus; the first distance is between 1 mm and 2 mm, the second distance is between 1 mm and 2 mm, and the third distance is between 1 mm and 2 mm.

[0009] A further solution is that the first distance, the second distance and the third distance are all equal; the first distance is 1.5 mm.

[0010] As can be seen from the above, through the design of the first focus, the second focus and the third focus, the focused ultrasound treatment head can meet most of the usage requirements of existing aesthetic medical treatments, thus improving the practicability of this focused ultrasound treatment head.

[0011] A further solution is that the surface of the bracket opposite to the membrane is a spherical crown surface; the first transducer, the second transducer and the third transducer are all installed on the spherical crown surface; the first transducer, the second transducer and the third transducer are all in the shape of a spherical quadrilateral, the width of the spherical quadrilateral is between 8 mm and 10 mm, and the length of the spherical quadrilateral is between 16 mm and 20 mm; the second transducer, the first transducer and the third transducer are distributed along the width direction of the spherical quadrilateral.

[0012] As can be seen from the above, through the structural design of each transducer, the accuracy of the positions of each focus can be guaranteed; at the same time, combined with the size design of each transducer, to make the size of the focused ultrasound treatment head more optimized and the volume smaller while ensuring that each transducer meets the usage requirements.

[0013] Another preferred solution is that the membrane is made of polyethylene, polyamide, polyimide, polyester, ethylene propylene diene monomer rubber, latex rubber or silicone rubber material.

[0014] As can be seen from the above, this design not only ensures that ultrasonic waves can normally penetrate the membrane, but also enables the membrane to block other frequency sound waves or electromagnetic waves, and at the same time makes the membrane have excellent heat insulation effect and mechanical properties.

[0015] Another preferred solution is that the accommodation cavity is filled with degassed water.

[0016] As can be seen from the above, since the energy of ultrasonic waves decays rapidly when propagating in the air, by filling degassed water in the accommodation cavity as a coupling agent between the human body and the ultrasonic transducer, ultrasonic attenuation can be effectively avoided, ensuring the treatment effect.

[0017] A further solution is that the focused ultrasonic treatment head further includes a terminal module, and the first transducer, the second transducer, and the third transducer are respectively electrically connected to the terminal module through cables.

[0018] As can be seen from the above, the above design makes the electrical connection between the external driving member (such as the handle of the operating handle) and each transducer faster and more convenient.

[0019] A further solution is that the housing further has a second opening communicating with the accommodation cavity, and the second opening and the first opening are distributed in the normal direction; the focused ultrasonic treatment head further includes a cover body, the cover body is sealed and installed on the housing and covers the second opening, the cover body has a through hole passing through itself, the terminal module covers the through hole, the terminal module is installed between the bracket and the cover body, the bracket is sealed and installed on the cover body, the bracket has a wire routing channel, and the cable is located in the wire routing channel; a connecting member is formed on the cover body, and the connecting member is located outside the accommodation cavity.

[0020] As can be seen from the above, this design makes the assembly between the bracket, the cover body and the housing more convenient and easy to operate; at the same time, through the wire routing channel on the bracket and by arranging the terminal module between the cover body and the bracket, the cable and the terminal module can be protected to prevent the degassed water in the cable and the terminal module from coming into contact.

[0021] To achieve another object of the present invention, the present invention provides an operating handle, including a handle, and further including the above-mentioned focused ultrasonic treatment head, and the focused ultrasonic treatment head is installed on the handle.

[0022] As can be seen from the above, the operating handle provided with the above-mentioned focused ultrasonic treatment head can perform operations with three different focal lengths (i.e., action depths) through the same ultrasonic treatment head, so that it is not necessary to frequently replace the focused ultrasonic treatment head during the treatment process. Only a single focused ultrasonic treatment head can be used to perform multi-level treatments on the human dermal layer, superficial fat layer, fascia layer, etc., which not only improves the convenience of operation, but also can improve efficiency, ensure the treatment effect, and at the same time can reduce the user's usage cost to a certain extent.

[0023] To achieve another object of the present invention, the present invention provides an ultrasonic beauty instrument, including a control end, and further including the above-mentioned operating handle, and the operating handle is electrically connected to the control end.

[0030] The present invention will be further described below in conjunction with the drawings and embodiments. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Embodiment of the focused ultrasonic treatment head

[0032] Referring to Figures 1 to 3 , the focused ultrasonic treatment head 100 includes a housing 1, a cover body 2, a bracket 3, a first transducer 4, a second transducer 5, a third transducer 6, and a terminal module 7.

[0033] The housing 1 has a receiving cavity 11 for receiving the bracket 3, the first transducer 4, the second transducer 5, the third transducer 6, etc. Among them, the acting end of the housing 1 has a first opening 12, and the first opening 12 communicates with the receiving cavity 11; a film 121 is installed at the first opening 12, and the film 121 is sealingly connected to the housing 1. Preferably, the film 121 can be made of polyethylene (PE), polyamide (PA), polyimide (PI), polyester, ethylene propylene diene monomer (EPDM) rubber, latex rubber, or silicone rubber materials to ensure that the ultrasonic waves generated by the first transducer 4, the second transducer 5, the third transducer 6, etc. can normally penetrate the film 121, and the film 121 can prevent other frequency sound waves or electromagnetic waves from passing through, and make the film 121 have excellent heat insulation effects and mechanical properties.

[0034] The housing 1 further has a second opening 13, and the second opening 13 communicates with the accommodating cavity 11. In order to optimize the structure of the focused ultrasound treatment head 100, in this embodiment, the first opening 12 and the second opening 13 are distributed along the normal direction of the membrane 121; of course, as an alternative solution, in other embodiments, the second opening 13 may also be formed on the side of the housing 1. In addition, as in this embodiment, the housing 1 is preferably substantially frustum-shaped.

[0035] The cover body 2 is installed on the housing 1, and the cover body 2 covers the second opening 13. Among them, the cover body 2 is preferably detachably connected to the housing 1 to facilitate the maintenance of each transducer; as Figure 3 and Figure 4 shown, in this embodiment, the housing 1 is formed with a connecting portion 111 on the inner cavity wall of the accommodating cavity 11. When the cover body 2 is provided with a connecting hole matching the connecting portion 111, when the cover body 2 is assembled with the housing 1, the cover body 2 and the housing 1 can be assembled and fixed by screwing the bolt through the connecting hole and then with the connecting portion 111. In addition, the cover body 2 and the housing 1 are hermetically connected. When the cover body 2 and the housing 1 are detachably connected, a sealing member can be used to seal the gap between the cover body 2 and the housing 1; when the cover body 2 and the housing 1 are non-detachably connected, welding can be used to hermetically connect the cover body 2 and the housing 1.

[0036] The cover body 2 is provided with a through hole 21, and the through hole 21 penetrates the cover body 2. The through hole 21 is preferably located at the middle position of the cover body 2. In addition, the cover body 2 is further formed with a connecting member 22, and the connecting member 22 is located outside the accommodating cavity 11. The connecting member 22 can be a snap structure, a magnetic attraction structure or other connecting structures with the same function; the setting of the connecting member 22 makes the assembly between the focused ultrasound treatment head 100 and an external driving component (such as the handle of an operating handle) simpler and more convenient, makes the focused ultrasound treatment head 100 replaceable relative to the operating handle, so that when the focused ultrasound treatment head 100 is damaged or fails, the focused ultrasound treatment head 100 can be removed from the handle and replaced or maintained.

[0037] The bracket 3 is installed in the accommodating cavity 11. Preferably, the bracket 3 is installed on the cover body 2 to make the assembly among the bracket 3, the cover body 2 and the housing 1 more convenient and easy to operate. The first transducer 4, the second transducer 5 and the third transducer 6 are all installed on the bracket 3, and the first transducer 4, the second transducer 5 and the third transducer 6 are all arranged facing the membrane 121. Among them, the first focus A of the first transducer 4, the second focus B of the second transducer 5 and the third focus C of the third transducer 6 are all located outside the accommodating cavity 11.

[0038] Combined Figure 3 and Figure 5, the first transducer 4 is located between the second transducer 5 and the third transducer 6. Among them, the first transducer 4 is generally horizontally distributed. There is a first angle distribution between the first transducer 4 and the second transducer 5, and a second angle distribution between the first transducer 4 and the third transducer 6, and the first angle is not equal to the second angle; specifically, the first angle between the first transducer 4 and the second transducer 5 is generally set as an obtuse angle, and the second angle between the first transducer 4 and the third transducer 6 is also generally set as an obtuse angle. In addition, the first transducer 4, the first focus A, the second focus B, and the third focus C are sequentially distributed in the normal direction of the membrane 121.

[0039] In the normal direction of the membrane 121, there is a first distance H1 between the first focus A and the membrane 121, a second distance H2 between the second focus B and the first focus A, and a third distance H3 between the third focus C and the second focus B; among them, the first distance H1 is preferably between 1 mm and 2 mm, the second distance H2 is preferably between 1 mm and 2 mm, and the third distance H3 is preferably between 1 mm and 2 mm. Through the design of the first focus A, the second focus B, and the third focus C, the focused ultrasound treatment head 100 can meet most of the usage requirements of existing medical aesthetic treatments, thereby improving the practicability of the focused ultrasound treatment head 100. Preferably, the first distance H1 is equal to the second distance H2, the second distance H2 is equal to the third distance H3, and the first distance H1, the second distance H2, and the third distance H3 are preferably all 1.5 mm.

[0040] In addition, the surface of the end of the bracket 3 close to the membrane 121 opposite to the membrane 121 is preferably a spherical crown surface 31. The first transducer 4, the second transducer 5, and the third transducer 6 are all installed on the spherical crown surface 31, and the first transducer 4, the second transducer 5, and the third transducer 6 are preferably fixed to the spherical crown surface 31 by gluing. Preferably, the first transducer 4, the second transducer 5, and the second transducer 5 are all in the shape of a spherical quadrilateral. Among them, the width W of the spherical quadrilateral is preferably between 8 mm and 10 mm, the length L of the spherical quadrilateral is preferably between 16 mm and 20 mm, and the second transducer 5, the first transducer 4, and the third transducer 6 are distributed along the width direction of the spherical quadrilateral; in this embodiment, for example, the width W of the spherical quadrilateral is 9 mm and the length L of the spherical quadrilateral is 18 mm. Through the structural design of each transducer, the accuracy of the positions of each focus can be guaranteed; at the same time, combined with the size design of each transducer, to make the size of the focused ultrasound treatment head 100 more optimized and the volume smaller while ensuring that each transducer meets the usage requirements.

[0041] Furthermore, the accommodation cavity 11 is filled with degassed water. Since the energy of ultrasonic waves decays rapidly when propagating in the air, filling the accommodation cavity 11 with degassed water as a coupling agent between the human body and the ultrasonic transducer can effectively avoid ultrasonic attenuation and ensure the treatment effect.

[0042] The terminal module 7 is electrically connected to the first transducer 4, the second transducer 5, and the third transducer through cables respectively. By providing the terminal module 7, the electrical connection between the external driving member (such as the handle of the operating handle) and each transducer is made faster and more convenient. Among them, the terminal module 7 is installed between the bracket 3 and the cover body 2, and the terminal module 7 covers the through hole 21 on the cover body 2; preferably, the cover body 2 is formed with a hole wall 211 in the circumferential direction of the through hole 21, and the hole wall 211 extends towards the inside of the accommodation cavity 11. The terminal module 7 is located at the protruding end of the hole wall 211, so that a sunken concave position is formed between the terminal module 7 and the hole wall 211, making the assembly of the focused ultrasound treatment head 100 and the external driving member more stable and reliable, so as to ensure the stability and reliability of the electrical connection between the terminal module 7 and the external driving member; at the same time, the design of the hole wall 211 is conducive to the sealed connection between the cover body 2 and the bracket 3.

[0043] Furthermore, the bracket 3 has a wire routing channel 32. The cables between the terminal module 7 and each transducer are located in the wire routing channel 32, and one end of the wire routing channel 32 close to the cover body 2 is sleeved on the hole wall 211, and the bracket 3 and the cover body 2 are hermetically connected; for example, in this embodiment, the connection between the bracket 3 and the cover body 2 is detachable. Therefore, a sealing member can be provided between the bracket 3 and the cover body 2 to seal the gap between the bracket 3 and the cover body 2 to prevent the degassed water in the accommodation cavity 11 from entering the wire routing channel 32; of course, in other embodiments, the connection between the bracket 3 and the cover body 2 can also be non-detachable. When the connection between the bracket 3 and the cover body 2 is non-detachable, the gap between the bracket 3 and the cover body 2 can be sealed by a welding process. By providing the wire routing channel 32 on the bracket 3 and arranging the terminal module 7 between the cover body 2 and the bracket 3, the cables and the terminal module 7 can be protected to prevent the degassed water inside the cables and the terminal module 7 from coming into contact.

[0044] In summary, through the design of the focused ultrasound treatment head 100 and the design of the relative positions between the first transducer 4, the second transducer 5, and the third transducer 6, the focused ultrasound treatment head 100 can perform operations with three different focal lengths (i.e., action depths), and during the treatment process, there is no need to frequently replace the focused ultrasound treatment head 100. Only by controlling different transducers through the control end can different focal length outputs be achieved, so that multi-level treatment of the human dermis, superficial fat layer, fascia layer, etc. can be carried out with a single focused ultrasound treatment head 100, which not only improves the convenience of operation, but also can improve efficiency, ensure the treatment effect, and at the same time can reduce the user's usage cost to a certain extent.

[0045] It should be noted that the first transducer 4, the second transducer 5, and the third transducer 6 can all operate independently. Of course, the first transducer 4, the second transducer 5, and the third transducer 6 can also operate in combination. For example, when the focused ultrasound treatment head 100 is working, at least two of the first transducer 4, the second transducer 5, and the third transducer 6 work simultaneously.

[0046] Embodiment of the operating handle

[0047] The operating handle includes a handle and the focused ultrasound treatment head described in the above-mentioned embodiment of the focused ultrasound treatment head. The focused ultrasound treatment head is mounted on the handle. During assembly, the focused ultrasound treatment head can be fixed to the handle through a connecting member and connected to the corresponding electrical contacts on the handle through a terminal module to establish an electrical connection between the focused ultrasound treatment head and the handle. Among them, a control module can be arranged inside the handle, so that the user can control at least one transducer of the focused ultrasound treatment head to work only by operating the control module of the handle; and / or, by operating the control end of the ultrasonic beauty instrument provided with this operating handle and cooperating with the handle to control at least one transducer of the focused ultrasound treatment head to work.

[0048] It can be seen that the operating handle provided with the above-mentioned focused ultrasound treatment head can perform operations with three different focal lengths (i.e., action depths) through the same ultrasound treatment head, so that there is no need to frequently replace the focused ultrasound treatment head during the treatment process. Only through a single focused ultrasound treatment head can multi-level treatments be performed on the human dermis, superficial fat layer, fascia layer, etc., which not only improves the convenience of operation, but also can improve efficiency, ensure the treatment effect, and at the same time can reduce the user's usage cost to a certain extent.

[0049] Embodiment of the ultrasonic beauty instrument

[0050] The ultrasonic beauty instrument includes a control end and the operating handle described in the above-mentioned embodiment of the operating handle. The handle of the operating handle is electrically connected to the control end. By setting the above-mentioned operating handle, the ultrasonic beauty instrument can perform operations with three different focal lengths (i.e., action depths) through the same focused ultrasound treatment head, so that there is no need to frequently replace the focused ultrasound treatment head during the treatment process. Only through a single focused ultrasound treatment head can multi-level treatments be performed on the human dermis, superficial fat layer, fascia layer, etc., which not only improves the convenience of operation, but also can improve efficiency, ensure the treatment effect, and at the same time can reduce the user's usage cost to a certain extent. Among them, the user can control one transducer in the focused ultrasound treatment head to operate independently through the control end, or can control more than two transducers in the focused ultrasound treatment head to operate in combination through the control end.

[0051] Finally, it should be emphasized that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
