Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic acupuncture treatment, in particular to a deeply narrowed linear focal region ultrasonic acupuncture device. Background Art

[0002] When an ultrasonic acupuncture device simulates the acupuncture area of traditional acupuncture, it usually requires ultrasonic focusing on a linear focusing area with a certain depth and breadth. Among them, the axicon lens has a wide application in ultrasonic acupuncture because the non-diffracting beam generated by it has a long propagation distance and a uniform transverse field distribution. Because the non-diffracting beam has the characteristic of a large focal depth linear focal region that is not affected by distance changes within a certain distance.

[0003] Although the ideal non-diffracting beam does not actually exist in physics because of its infinite propagation range, the finite aperture of the axicon acoustic lens enables it to approximately maintain this characteristic, that is, within a limited propagation range, the shape of the transverse field distribution remains basically unchanged, forming a linear focal region;

[0004] However, in the prior art, since the axicon acoustic lens itself is difficult to process, especially in ultrasonic acupuncture treatment, to obtain a deeper focal depth, it is necessary to reduce the bottom angle of the axicon and increase the non-diffracting distance of the beam. Eventually, the processing of the conical surface of the axicon acoustic lens is more difficult, resulting in that the required focal depth in the existing ultrasonic acupuncture treatment is always difficult to meet and no deeper breakthrough can be obtained.

[0005] Therefore, it is necessary to design a deeply narrowed linear focal region ultrasonic acupuncture device that is convenient for processing and transforming the axicon acoustic lens, further generates a non-diffracting beam with a long propagation distance and a uniform transverse field distribution, and is applied to ultrasonic acupuncture treatment to obtain a large focal depth linear focal region. Summary of the Invention

[0007] The purpose of the present utility model is to provide a deeply narrowed linear focal region ultrasonic acupuncture device, aiming to solve the problem in the prior art that the required focal depth in the existing ultrasonic acupuncture treatment is always difficult to meet and no deeper breakthrough can be obtained due to the extremely difficult processing of the conical surface of the axicon acoustic lens.

[0037] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0038] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an embodiment that is separate from or mutually exclusive of other embodiments selectively.

[0039] Embodiment 1

[0040] Referring to Figure 1 、 Figures 3 to 5 、 Figures 8 to 10 , this is the first embodiment of the present utility model. This embodiment provides a deeply narrowed linear focal region ultrasonic acupuncture device, including an ultrasonic acupuncture main body 100, which includes a linear focal region forming assembly 101, a bearing housing 102 arranged on one side of the linear focal region forming assembly 101, and a spiral suction cup 103 arranged on one side of the bearing housing 102;

[0041] On both sides of the shaft pyramid acoustic lens 101a in the linear focal region forming assembly 101 are respectively a special-shaped bottom surface 101a-1 and a conical surface 101a-2.

[0042] Furthermore, the linear focal region forming component 101 further includes a transducer probe 101b disposed on one side of the axicon acoustic lens 101a, and an ultrasonic conduction material filling 101c disposed on one side of the axicon acoustic lens 101a.

[0043] It should be noted that the transducer probe 101b is used to generate and output ultrasonic waves.

[0044] Furthermore, the ultrasonic radiation surface of the transducer probe 101b is a plane.

[0045] Furthermore, the special-shaped bottom surface 101a-1 is a conical surface, and the base angle of the special-shaped bottom surface 101a-1 is smaller than the base angle of the conical surface 101a-2;

[0046] When the base angle of the conical surface 101a-2 remains unchanged, the depth and narrowness of the formed linear focal region are positively correlated with the change in the base angle of the conical-shaped bottom surface 101a-1 of the cone.

[0047] It should be noted that in this embodiment, let the base angle of the conical surface 101a-2 be γ2, and let the base angle of the conical-shaped bottom surface 101a-1 of the cone be γ1;

[0048] The axicon acoustic lens 101a in this embodiment, its conical-shaped bottom surface 101a-1 of the cone is processed on the basis of the traditional axicon acoustic lens structure (refer to Figure 3 ). Taking the axis of the axicon as the center, the bottom surface of the axicon is ground into a conical-shaped bottom surface 101a-1 with a base angle γ1 smaller than the base angle γ2 of the conical surface 101a-2. The combination of the conical surface 101a-2 and the conical-shaped bottom surface 101a-1 of the cone is also called a double-cone axicon acoustic lens; after one end of the conical surface 101a-2 of the double-cone axicon lens is filled with ultrasonic conduction material, the conical-shaped bottom surface 101a-1 side can be adapted to the shape of the ultrasonic radiation surface with a planar shape of the transducer probe 101b, and the conical surface 101a-2 side can be adapted to the contact plane of the human skin.

[0049] Preferably, when the base angle γ2 of the conical surface 101a-2 is fixed, increasing the base angle γ1 of the conical-shaped bottom surface 101a-1 of the cone can obtain a longer non-diffracting distance, that is, obtain a linear focal region with a larger focal depth.

[0050] Furthermore, the aperture range of the axicon acoustic lens 101a is 10 - 1100 mm, the mouth depth range of the rear end surface of the axicon acoustic lens 101a is 5 - 25 mm, and the mouth depth range of the front end surface of the axicon acoustic lens 101a is 5 - 25 mm;

[0051] The axicon acoustic lens 101a is made of copper material with good ultrasonic conductivity.

[0052] Further, the ultrasonic frequency range emitted by the transducer probe 101b is 0.8 - 20 MHz.

[0053] Further, the materials that can be selected for the ultrasonic conduction material filling 101c at least include one of silica gel, polystyrene, and polymethyl methacrylate.

[0054] It should be noted that after curing, the ultrasonic conduction material filling 101c is adapted to the ultrasonic radiation surface of the transducer probe 101b and / or the contact plane with the human skin.

[0055] During use, the sound waves radiated from the ultrasonic radiation surface of the transducer probe 101b are conducted to the conical surface special-shaped bottom surface 101a-1 through the ultrasonic conduction material filling 101c, and after refraction by the conical surface special-shaped bottom surface 101a-1, they form parallel light beams deflected outward from the axis. Finally, after refraction by the conical surface 101a-2, they are focused in front of the double-cone axis pyramid acoustic lens and form a rhombus region with a length of Zmax as shown in Figure 5 The rhombus region is the required linear focal region.

[0056] Preferably, for the simulation schematic diagram of the large focal depth linear focal region formed by the double-cone axis pyramid acoustic lens of this embodiment, refer to Figure 10 , compared with the case without adding the axis pyramid acoustic lens under the same parameters (refer to Figure 8 ), and the simulation schematic diagram of the traditional axis pyramid focal region acoustic lens (refer to Figure 9 ), the double-cone axis pyramid acoustic lens in this embodiment can significantly broaden the focal depth of the linear focal region, reduce the side lobes, make the transverse field distribution uniform, and obtain a narrower and deeper linear focal region.

[0057] In summary, the double-cone axis pyramid acoustic lens obtained by adding the designed conical surface special-shaped bottom surface 101a-1 in the present utility model can generate non-diffracting beams with a long propagation distance and a uniform transverse field distribution only by increasing the base angle γ1 of the conical surface special-shaped bottom surface 101a-1, greatly reducing the requirements for processing accuracy and technical difficulty. Under the same parameter conditions, it can obtain non-diffracting beams with a long longitudinal field propagation distance and a uniform transverse field distribution, which can not only meet the required focal depth in the existing ultrasonic acupuncture treatment, but also achieve a deeper breakthrough.

[0058] Embodiment 2

[0059] Referring to Figure 1 , Figure 3 , Figures 6 to 9 , Figure 11 , this is the second embodiment of the present utility model, including an ultrasonic acupuncture main body 100, which includes a linear focal region forming component 101, a carrying shell 102 arranged on one side of the linear focal region forming component 101, and a spiral suction cup 103 arranged on one side of the carrying shell 102;

[0060] On both sides of the axicon acoustic lens 101a in the linear focal region forming component 101 are respectively a special-shaped bottom surface 101a-1 and a conical surface 101a-2.

[0061] Furthermore, the linear focal region forming component 101 further includes a transducer probe 101b disposed on one side of the axicon acoustic lens 101a, and an ultrasonic conduction material filling 101c disposed on one side of the axicon acoustic lens 101a.

[0062] It should be noted that the transducer probe 101b is used to generate and output ultrasonic waves.

[0063] Furthermore, the ultrasonic radiation surface of the transducer probe 101b is a spherical crown-shaped curved surface.

[0064] Furthermore, the special-shaped bottom surface 101a-1 is a concave spherical surface;

[0065] When the base angle of the conical surface 101a-2 remains unchanged,

[0066] The depth and narrowness of the linear focal region formation are negatively correlated with the change in the radius of curvature of the concave spherical special-shaped bottom surface 101a-1.

[0067] It should be noted that in this embodiment, let the base angle of the conical surface 101a-2 be γ, and the radius of curvature of the concave spherical special-shaped bottom surface 101a-1 be R;

[0068] The axicon acoustic lens 101a in this embodiment, its concave spherical special-shaped bottom surface 101a-1 is processed on the basis of the traditional axicon acoustic lens structure (refer to Figure 3 ). Taking the axis of the axicon as the center, the bottom surface of the axicon is ground into a concave spherical special-shaped bottom surface 101a-1 with a radius of curvature R meeting the requirements. The combination of the conical surface 101a-2 and the concave spherical special-shaped bottom surface 101a-1 is also called a concave conical axicon acoustic lens; after one end of the conical surface 101a-2 of the concave conical axicon lens is filled with ultrasonic conduction material, the concave spherical special-shaped bottom surface 101a-1 side can be adapted to the shape of the ultrasonic radiation surface of the spherical crown-shaped curved surface of the transducer probe 101b, and the conical surface 101a-2 side can be adapted to the contact plane of the human skin.

[0069] Preferably, when the base angle γ of the conical surface 101a-2 is fixed, reducing the radius of curvature R of the concave spherical special-shaped bottom surface 101a-1 can obtain a longer non-diffraction distance, that is, obtain a linear focal region with a larger focal depth. Reducing the radius of curvature R of the concave spherical special-shaped bottom surface 101a-1 is actually increasing the base angle of the concave spherical special-shaped bottom surface 101a-1.

[0070] Furthermore, the aperture range of the axicon acoustic lens 101a is 10 - 1100 mm, the depth of the rear end face of the axicon acoustic lens 101a is in the range of 5 - 25 mm, and the depth of the front end face of the axicon acoustic lens 101a is in the range of 5 - 25 mm;

[0071] The axicon acoustic lens 101a is made of copper with good ultrasonic conductivity.

[0072] Furthermore, the ultrasonic frequency range emitted by the transducer probe 101b is 0.8 - 20 MHz.

[0073] Furthermore, the materials that can be selected for the ultrasonic conduction material filling 101c at least include one of silicone, polystyrene, and polymethyl methacrylate.

[0074] It should be noted that after curing, the ultrasonic conduction material filling 101c is adapted to the ultrasonic radiation surface of the transducer probe 101b and / or the contact plane with the human skin.

[0075] During use, the sound waves radiated from the ultrasonic radiation surface of the transducer probe 101b are refracted twice at the special-shaped bottom surface 101a-1 of the concave spherical surface and the conical surface 101a-2, conducted through the ultrasonic conduction material filling 101c to the special-shaped bottom surface 101a-1 of the concave spherical surface, and form a divergent spherical wave after refraction by the special-shaped bottom surface 101a-1 of the concave spherical surface. The curvature radius R of the special-shaped bottom surface 101a-1 of the concave spherical surface is reduced to reduce the sound wave inclination. Finally, after refraction by the conical surface 101a-2, it is focused in front of the concave conical axicon acoustic lens and forms a rhombus region with a length of Zmax as shown in Figure 7 The rhombus region is the required linear focal region.

[0076] Preferably, for the schematic diagram of the large focal depth linear focal region formed by the concave conical axicon acoustic lens in this embodiment, see Figure 11 , compared with the case without adding an axicon acoustic lens under the same parameters (see Figure 8 ) and the simulation schematic diagram of the traditional axicon focal region acoustic lens (see Figure 9 ), it can significantly broaden the focal depth of the linear focal region, reduce the side lobes, make the transverse field distribution uniform, and obtain a narrower and deeper linear focal region.

[0077] In summary, the concave conical axicon acoustic lens obtained by adding the special-shaped bottom surface 101a-1 with a concave spherical surface in the present utility model can generate a non-diffracting beam with a long propagation distance and a uniform transverse field distribution only by reducing the curvature radius R of the special-shaped bottom surface 101a-1 of the concave spherical surface. At this time, the base angle of the special-shaped bottom surface 101a-1 of the concave spherical surface actually increases due to the reduction of the curvature radius R, greatly reducing the processing accuracy requirements and technical difficulties. Under the same parameter conditions, a non-diffracting beam with a large focal depth, a long longitudinal field propagation distance, and a uniform transverse field distribution can be obtained, which can not only meet the focal depth required in the existing ultrasonic acupuncture treatment, but also achieve a deeper breakthrough.

[0078] Embodiment 3

[0079] Refer to Figures 1 to 2 , which is the third embodiment of the present utility model, including an ultrasonic acupuncture main body 100, including a linear focal region forming component 101, a bearing housing 102 arranged on one side of the linear focal region forming component 101, and a spiral suction cup 103 arranged on one side of the bearing housing 102;

[0080] On both sides of the axicon acoustic lens 101a in the linear focal region forming component 101 are a special-shaped bottom surface 101a-1 and a conical surface 101a-2 respectively.

[0081] Furthermore, the spiral suction cup 103 includes a base knob 103a, a connecting piece 103b arranged on one side of the base knob 103a, a suction cup base 103c arranged on one side of the connecting piece 103b, a treatment window 103d opened on the bottom side of the suction cup base 103c, and a sound-transmitting film 103e arranged on one side of the treatment window 103d.

[0082] It should be noted that the sound-transmitting film 103e can be made of materials such as TPU with soft texture and good biocompatibility. The selection of the thickness and material of the sound-transmitting film 103e is adjusted according to different actual application requirements; components required for equipment operation such as the linear focal region forming component 102, electronic control components, and wires are installed in the inner cavity of the bearing housing 102.

[0083] Preferably, the sound-transmitting film 103e can form an isolation and protection barrier between the linear focal region forming component 101 and the human body, avoiding direct contact between the linear focal region forming component 101 and the human body, which can not only avoid the stimulation of the equipment to the human body, but also reduce noise interference;

[0084] When the spiral suction cup 103 adheres to the skin surface, the air in the space behind the spiral suction cup 103 is discharged by extrusion, creating a lower air pressure inside. According to the principle of air pressure equilibrium in nature, the external atmospheric pressure will press the suction cup tightly against the skin and generate a relatively large adsorption force. When using a medical ultrasonic instrument, coupling agent is usually applied to avoid the existence of air between the human body and the instrument, ensuring good ultrasonic propagation efficiency. In this embodiment, through the arranged spiral suction cup 103, the human body and the spiral suction cup 103 are fully fitted, which not only effectively reduces the probability of air existence, but also greatly reduces the use of coupling agent. Through the combined use of the spiral suction cup 103 and the coupling agent in this embodiment, the good ultrasonic propagation efficiency is further ensured.

[0085] During use, the spiral suction cup 103 arranged on one side of the bearing housing 102 is further tightened by rotating the base knob 103a, so that the ultrasonic acupuncture device is closely attached to the human skin surface.

[0086] In summary, by making the spiral suction cup 103 closely attached to the human skin surface, the use of ultrasonic coupling agent during treatment is reduced.

[0087] Importantly, the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
