[0063] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0064] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0065] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0066] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0067] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0068] The present application provides an artificial ear, such as Figure 1 to Figure 5 As shown, the artificial ear includes: a first part 1 and a second part 2, the first part 1 includes a first body 11 and a first connecting part 12 arranged on the first body 11, and the first body 11 has the outline of an ear; the second part 2 is used to be adhered to the wearing part of the patient, the second part 2 includes a second body 21 and a second connecting part 22 arranged on the second body 21, and the second connecting part 22 can cooperate with the first connecting part 12 to realize the connection between the first part 1 and the second part 2.

[0069] Since the first part 1 and the second part 2 are detachably connected, after the second part 2 is adhered to the patient's wearing part, the patient can easily wear or remove the first part 1 without surgery, and there is no risk of trauma infection to the patient.

[0070] Specifically, the second part 2 is adhered to the patient's wearing part by medical glue or the like. Since the medical glue is relatively safe, it can reduce discomfort reactions such as itching and ulceration caused by wearing the artificial ear for a long time.

[0071] More specifically, the first body 11 has skin texture and blood vessel texture. By providing the skin texture and blood vessel texture on the first body 11, the artificial ear can restore the structure of a real human ear, increase the authenticity and three-dimensional sense of the artificial ear, and thus reduce the patient's rejection of the artificial ear. In addition, the skin texture and blood vessel texture on the first body 11 can correspond to the patient's normal ear.

[0072] Furthermore, the cooperation between the first connection portion 12 and the second connection portion 22 may be a snap connection to ensure the connection reliability of the first connection portion 12 and the second connection portion 22 .

[0073] Regarding the specific structures of the first connecting portion 12 and the second connecting portion 22 , the present application provides the following various embodiments.

[0074] Embodiment 1

[0075] In this embodiment, if Figure 3 to Figure 5 As shown, the first connecting portion 12 has an extension section 121 and a first limit block 122, the extension section 121 connects the first body 11 and the first limit block 122, and the first limit block 122 protrudes from the extension section 121 along the radial direction of the first body 11; the second connecting portion 22 has a slide rail 221 and a second limit block 222, and the extension section 121 can slide in the slide rail 221 so that the first limit block 122 and the second limit block 222 abut against each other for limiting.

[0076] like Figure 3 to Figure 5 As shown, through the abutment and limiting of the first limiting block 122 and the second limiting block 222 , the first part 1 and the second part 2 are reliably connected, and the first part 1 will not fall off from the second part 2 .

[0077] Specifically, when wearing the artificial ear, firstly, the first stopper 122 and at least part of the extension section 121 are extended into the slide rail 221, and then the first body 11 is rotated so that the first stopper 122 slides along the slide rail 221, thereby abutting against the second stopper 222. When removing the artificial ear, the first body 11 is rotated so that the first stopper 122 slides along the slide rail 221, so as to separate from the second stopper 222, and then can be removed from the slide rail 221. Therefore, the wearing and removing process of the artificial ear is simple, and the patient can wear or remove it quickly.

[0078] More specifically, the slide rail 221 is arc-shaped, and along the circumference of the second body 21, the second limit block 222 is disposed at one end of the slide rail 221. When the first body 11 rotates, the movement path of the first limit block 122 corresponds to the shape of the slide rail 221, so that the first limit block 122 can slide smoothly along the slide rail 221. Figure 4 As shown, the two side walls of the extension section 121 distributed along the radial direction of the first body 11 are both arc-shaped surfaces.

[0079] Optionally, the first limit block 122 protrudes from the extension section 121 in a radial direction of the first body 11 toward or away from the center of the first body 11. Accordingly, when the first limit block 122 protrudes toward the center of the first body 11, the second limit block 222 is disposed on a side of the slide rail 221 that is close to the center of the second body 21; when the first limit block 122 protrudes toward the center away from the first body 11, the second limit block 222 is disposed on a side of the slide rail 221 that is away from the center of the second body 21.

[0080] Embodiment 2

[0081] In this embodiment, if Figure 6 to Figure 8 As shown, the first connection part 12 has a first protrusion 123, and the second connection part 22 has a second protrusion 223 and a third protrusion 224 arranged at intervals. When the first protrusion 123 extends between the second protrusion 223 and the third protrusion 224, it abuts against at least one of the second protrusion 223 and the third protrusion 224.

[0082] like Figure 6 to Figure 8 As shown, by the abutment and limiting of the first protrusion 123 by the second protrusion 223 and the third protrusion 224, the first part 1 and the second part 2 are reliably connected, so that the first part 1 will not rotate relative to the second part 2. Among them, the distance between the second protrusion 223 and the third protrusion 224 can be slightly smaller than the width of the first protrusion 123, so that the first protrusion 123 and the groove between the second protrusion 223 and the third protrusion 224 are interference-fitted, so that the first part 1 will not fall off from the second part 2.

[0083] Specifically, when wearing the artificial ear, the first protrusion 123 is inserted between the second protrusion 223 and the third protrusion 224, and the second protrusion 223 and the third protrusion 224 lock the first protrusion 123; when removing the artificial ear, the first protrusion 123 is removed from between the second protrusion 223 and the third protrusion 224 by grabbing the first part 1. Therefore, the wearing and removing process of the artificial ear is simple, and the patient can wear or remove it quickly.

[0084] More specifically, the height of the first protrusion 123 is greater than or equal to the height of the second protrusion 223 or the height of the third protrusion 224 to ensure the matching reliability of the first protrusion 123 and the second protrusion 223 or the third protrusion 224 .

[0085] Further, such as Figure 7 and Figure 8 As shown, the first protrusion 123 and the first body 11 are connected via a reinforcing protrusion 124 , and the cross-sectional dimension of the reinforcing protrusion 124 is greater than or equal to the cross-sectional dimension of the first protrusion 123 , thereby ensuring the structural strength of the first connecting portion 12 .

[0086] Furthermore, Figure 8 As shown, the second protrusion 223 has an arc-shaped guide surface 223 a, and the guide surface 223 a can guide the first protrusion 123 .

[0087] When wearing the artificial ear, the first protrusion 123 can contact the guide surface 223a of the second protrusion 223 and slide along the guide surface 223a, so that the first protrusion 123 extends between the second protrusion 223 and the third protrusion 224 and is locked by the second protrusion 223 and the third protrusion 224, thereby reducing the difficulty of wearing the artificial ear and improving the patient's usage experience.

[0088] Embodiment 3

[0089] In this embodiment, if Figures 9 to 12 As shown, the first connecting part 12 has a limiting protrusion 125 and a button 126, the limiting protrusion 125 is connected to the first body 11, the button 126 can slide relative to the limiting protrusion 125, and the button 126 has a clamping part 126a; the second connecting part 22 has a connecting protrusion 225, and the connecting protrusion 225 can be clamped by the clamping part 126a and the limiting protrusion 125.

[0090] like Figures 9 to 12 As shown, by the clamping and limiting of the connection protrusion 225 by the clamping portion 126a and the limiting protrusion 125, the first part 1 and the second part 2 are reliably connected, and the first part 1 will not fall off from the second part 2.

[0091] Specifically, Fig.11 As shown, the button 126 also has a pressing portion 126b and a connecting arm 126c, and the connecting arm 126c connects the clamping portion 126a and the pressing portion 126b so that the clamping portion 126a and the pressing portion 126b are located on both sides of the limiting protrusion 125; the first connecting portion 12 also has an elastic member 127, one end of the elastic member 127 abuts against the pressing portion 126b, and the other end abuts against the limiting protrusion 125.

[0092] The elastic member 127 can apply elastic force to the pressing portion 126b, so that the clamping portion 126a moves toward the limiting protrusion 125 or has a movement tendency toward the limiting protrusion 125, so that the clamping portion 126a and the limiting protrusion 125 can tightly clamp the connecting protrusion 225 to achieve a reliable connection between the first part 1 and the second part 2.

[0093] like Fig.11 As shown, the button 126 has two connecting arms 126c, and the two connecting arms 126c are connected to the pressing portion 126b at intervals, so that the limiting protrusion 125 can be located between the two connecting arms 126c. One end of the connecting arm 126c away from the pressing portion 126b is connected to the clamping portion 126a, and the two clamping portions 126a on the two connecting arms 126c extend toward each other.

[0094] More specifically, when wearing the artificial ear, first press the pressing portion 126b to make the button 126 move as a whole toward the center of the first body 11. At this time, the clamping portion 126a is away from the limiting protrusion 125, and the distance between the two increases, so that the connecting protrusion 225 can be inserted between the clamping portion 126a and the limiting protrusion 125. Then, the pressing of the pressing portion 126b is released, and the button 126 moves as a whole toward the center of the first body 11 under the elastic force of the elastic member 127. The clamping portion 126a approaches the limiting protrusion 125, and the connecting protrusion 225 is clamped. Correspondingly, when removing the artificial ear, first press the pressing portion 126b to make the button 126 move as a whole toward the center of the first body 11. At this time, the clamping portion 126a is away from the limiting protrusion 125, and the distance between the two increases, so that the connecting protrusion 225 can fall out from between the clamping portion 126a and the limiting protrusion 125. Therefore, the process of wearing and removing the artificial ear is simple, and the patient can wear or remove it quickly.

[0095] like Fig.10 and Fig.12 As shown, the first body 11 is provided with a first groove 111, and the second body 21 is provided with a second groove 211. When the first part 1 is connected with the second part 2, the first groove 111 is connected with the second groove 211, and at least part of the button 126 can slide in the first groove 111 and the second groove 211. The limiting protrusion 125 is provided in the first groove 111, and the limiting protrusion 125 is provided with a mounting column 125a, and the elastic member 127 is sleeved on the mounting column 125a, so as to prevent the elastic member 127 from falling off, and improve the reliability of the connection between the first connecting part 12 and the second connecting part 22. Among them, the elastic member 127 can be specifically a spring, etc.

[0096] Further, such as Fig.11 As shown, a limiting portion 126d is further provided on the connecting arm 126c, and the limiting portion 126d can abut against the first body 11, thereby limiting the movement range of the button 126 relative to the first body 11. Specifically, the limiting portion 126d and the clamping portion 126a are respectively provided on both sides of the connecting arm 126c, and the limiting portion 126d can abut against the side wall 112 of the first groove 111.

[0097] like Fig.12As shown, the connection protrusion 225 is disposed in the second groove 211, and the first connection portion 12 further has an avoidance block 226 connected to the connection protrusion 225. When the first connection portion 12 and the second connection portion 22 are matched, the avoidance block 226 can extend between the two clamping blocks 126a, thereby improving the matching tightness of the first connection portion 12 and the second connection portion 22, and further improving the connection reliability of the two.

[0098] In the above embodiments, Figure 3 , Figure 6 and Fig. 9 As shown, a plurality of first connection parts 12 are symmetrically arranged on the first body 11, and / or, as shown Figure 5 , Figure 8 and Fig.12 As shown, a plurality of second connection parts 22 are symmetrically arranged on the second body 21, thereby further improving the connection reliability between the first part 1 and the second part 2. Preferably, two first connection parts 12 and two second connection parts 22 are arranged.

[0099] In the above embodiments, Figure 2 As shown, the first part 1 further includes a first magnetic member 13 disposed on the first body 11, and the second part 2 further includes a second magnetic member 23 disposed on the second body 21, and the first magnetic member 13 and the second magnetic member 23 attract each other.

[0100] When the first part 1 is close to the second part 2, the first magnetic part 13 and the second magnetic part 23 attract each other, so that the first part 1 and the second part 2 are pre-connected. At this time, the first part 1 and the second part 2 can be adjusted more conveniently, so that the first connecting part 12 and the second connecting part 22 cooperate, and the artificial ear 1 can be quickly worn. At the same time, the mutual attraction of the first magnetic part 13 and the second magnetic part 23 improves the connection reliability of the first part 1 and the second part 2.

[0101] In the above embodiments, the first part 1 further includes a support portion, which is disposed in the first body 11 to support the first body 11. The hardness of the support portion is greater than the hardness of the first body 11. The first body 11 reflects the mechanical properties of soft materials, and the support portion reflects the mechanical properties of hard materials, so that the artificial ear is closer to a real human ear.

[0102] Specifically, the support portion is disposed at at least one position of the helix, antihelix, antihelix crus, scaphoid and earlobe corresponding to the first body 11 to highly simulate the complex structure of the human ear.

[0103] Optionally, the first body 11, the support part, the first connection part 12, and the second connection part 22 can be generated by 3D printing. By scanning the shape of the patient's normal ear, a three-dimensional model of the artificial ear is designed, and then the three-dimensionally printed first body 11, the support part, the first connection part 12, and the second connection part 22 are obtained by printing layer by layer through 3D printing technology. Optionally, the first connection part 12 and the second connection part 22 can be obtained by purchasing standard parts or other technologies known in the art.

[0104] Among them, exemplary 3D printing technologies that can be used include, but are not limited to: stereolithography (SLA), digital light processing (DLP), three-dimensional printing technology (3DP), three-dimensional inkjet printing technology (MJP), multi-jet melting technology (MJF), and various other types of 3D printing or additive manufacturing technologies known in the art, which are not limited in this application.

[0105] Furthermore, the artificial ear can be formed by printing and manufacturing a combination of soft materials and hard materials through 3D printing technology. The internal structure of the human ear has different degrees of softness and hardness. Based on the different degrees of hardness of the internal structure of the human ear, the artificial ear is formed by printing and manufacturing a combination of soft materials and hard materials, so as to achieve a better simulation effect and give the artificial ear a more realistic touch. In one example, the soft material and the hard material include a resin material and / or a silicone material.

[0106] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
