Description

Technical Field

[0001] The present application relates to the technical field of medical instruments, and in particular to an otolith repositioning model and an otolith repositioning device. Background Art

[0002] Otolith vertigo, also known as benign paroxysmal positional vertigo, refers to short-term paroxysmal attacks of vertigo and nystagmus that occur when a vertebrate's head moves rapidly to a certain head position. Under normal circumstances, otoliths are located in the utricle of the vestibule. Due to head trauma or local structural degeneration due to aging, otoliths will fall off from the utricle and move to the semicircular canals. When the body position of the organism changes, the otoliths move in the semicircular canals with the action of gravity, stimulating the vestibular endings and inducing vertigo.

[0003] The clinical treatment for otolithiasis is "manual repositioning therapy". The doctor asks the patient to quickly change different body positions and change the position of the patient's head, so that the detached otoliths can return to the utricle through gravity, so that it can no longer stimulate nerve endings and eliminate the patient's dizziness symptoms.

[0004] Currently, doctors can diagnose otolithiasis based on the patient's typical clinical manifestations. However, because the anatomical structure of the inner ear vestibule and semicircular canals is relatively abstract, it is difficult for doctors to imagine the position and movement trajectory of the otoliths. It is difficult for doctors to accurately judge the position of the semicircular canals and otoliths in each body position during the actual repositioning process, which is not conducive to the rapid and accurate repositioning of the otoliths. The treatment success rate and efficiency of otolith vertigo are low, and the patient's treatment experience is poor. Utility Model Content

[0005] In view of this, the present application provides an otolith repositioning model and an otolith repositioning device. The otolith repositioning model and the otolith repositioning device of the present application can improve the treatment success rate and treatment efficiency for otolith vertigo, and the patient has a better treatment experience.

[0006] In the first aspect, the present application provides an otolith resetting model, which includes a semicircular canal, an otolith, a guide and a limiter. The semicircular canal is used to simulate the organ in charge of the sense of balance in the inner ear labyrinth of vertebrates. The semicircular canal includes a main body and an ampulla, both of which are tubular, the main body is provided with a first accommodating cavity, the ampulla is provided with a second accommodating cavity, and the first accommodating cavity and the second accommodating cavity are connected. The otolith is used to simulate the calcareous stones in the inner ear of vertebrates, and the otolith can be located in the first accommodating cavity or the second accommodating cavity. The guide is connected to the semicircular canal, the limiter is movably connected to the guide, and the limiter can be located in a first position or a second position relative to the guide. When the user operates the limiter to move to the first position relative to the guide, the limiter is close to the ampulla, and under the condition that the otolith moves to the second accommodating cavity, the limiter can be magnetically attracted to the otolith located in the second accommodating cavity, and the magnetic attraction between the limiter and the otolith is strong, and the magnetic attraction can limit the otolith to the second accommodating cavity. If the otoliths are confined to the second accommodating cavity, the otolith repositioning model can be used to simulate crista cap calculi (a situation in which the otoliths originally located in the utricle in the inner ear of vertebrates move to and adhere to the crista cap of the ampulla). When the user operates the limiter to move to the second position relative to the guide member, the limiter is away from the ampulla, and even if the otoliths can move to the second accommodating cavity, the magnetic attraction between the limiter and the otoliths is weak, and the magnetic attraction cannot confine the otoliths to the second accommodating cavity, that is, the otoliths can move between the first accommodating cavity and the second accommodating cavity. If the otoliths can move freely between the first accommodating cavity and the second accommodating cavity, the otolith repositioning model can be used to simulate otolith vertigo (a situation in which the otoliths originally located in the utricle in the inner ear of vertebrates move freely in the semicircular canals). Doctors can use the otolith repositioning model to simulate treatment plans for crista cap calculi and otolith vertigo to improve the doctor's treatment success rate and treatment efficiency, and the patients receiving treatment have a better treatment experience. For patients with otolith vertigo, the patient's head can wear an otolith resetting model (the limiter is located in the second position), and the doctor can judge the current position of the otoliths in the semicircular canals of the patient in a certain position (such as lying flat, lying on the side, half lying or sitting). The doctor instructs the patient to change the position according to the observed position. After the patient changes the position, the otoliths will move in the semicircular canals. The doctor determines whether the otoliths move toward the ampulla according to the movement trajectory of the otoliths in the semicircular canals to determine whether the patient's otoliths are reset to the utricle (the utricle is connected to the ampulla in the inner ear labyrinth of vertebrates). Therefore, the doctor can easily judge the position of the patient's otoliths and easily instruct the patient to change the appropriate position by intuitively observing the position of the otoliths of the otolith resetting model in the semicircular canals. The treatment success rate and treatment efficiency for otolith vertigo are high, and the patient's treatment experience is good. Since the guide member and the limiting member are movably connected, that is, the limiting member is limited to the guide member, when the user uses the otolith resetting model, the limiting member is not easily lost, or the user does not need to save the limiting member separately, and the user experience is better.Secondly, the guide member has a guiding function for the limiting member, so that the user can easily change the position of the limiting member to the first position or the second position, the user's operation difficulty is low, and the user's use experience is better.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] First, please refer to Figure 1-Figure 4 As shown, an embodiment of the present application provides an otolith repositioning model 10, which includes a semicircular canal 1, an otolith 2, a guide 3 and a limiter 4. The semicircular canal 1 is used to simulate the organ in the inner ear labyrinth of vertebrates that controls the sense of balance. The semicircular canal 1 includes a main body 11 and an ampulla 12. The main body 11 and the ampulla 12 are both tubular. The main body 11 is provided with a first accommodating cavity 111, and the ampulla 12 is provided with a second accommodating cavity 121. The first accommodating cavity 111 and the second accommodating cavity 121 are connected. The otolith 2 is used to simulate the calcareous stones in the inner ear of vertebrates. The otolith 2 can be located in the first accommodating cavity 111 or the second accommodating cavity 121. The guide 3 is connected to the semicircular canal 1, and the limiter 4 is movably connected to the guide 3. The limiter 4 can be located relative to the guide 3 as follows: Figure 3 The first position shown or Figure 4 The second position is shown.

[0079] Please refer to Figure 3 As shown, when the user operates the limiter 4 to move to the first position relative to the guide member 3, the limiter 4 is close to the ampulla 12, and under the condition that the otolith 2 moves to the second accommodating cavity 121, the limiter 4 can be magnetically attracted to the otolith 2 located in the second accommodating cavity 121, and the magnetic attraction between the limiter 4 and the otolith 2 is relatively strong, and the magnetic attraction can limit the otolith 2 to the second accommodating cavity 121. If the otolith 2 is limited to the second accommodating cavity 121, the otolith repositioning model 10 can be used to simulate ridge cap calculi (the situation where the otolith originally located in the utricle in the inner ear of vertebrates moves to and adheres to the ridge cap of the ampulla).

[0080] Please refer to Figure 4As shown, when the user operates the limiter 4 to move to the second position relative to the guide member 3, the limiter 4 is away from the ampulla 12. Even if the otolith 2 can move to the second accommodating cavity 121, the magnetic attraction between the limiter 4 and the otolith 2 is weak, and the magnetic attraction cannot limit the otolith 2 to the second accommodating cavity 121, that is, the otolith 2 can move between the first accommodating cavity 111 and the second accommodating cavity 121. If the otolith 2 can move freely between the first accommodating cavity 111 and the second accommodating cavity 121, the otolith repositioning model 10 can be used to simulate otolith vertigo (the situation where the otoliths originally located in the utricle in the inner ear of vertebrates move freely in the semicircular canals).

[0081] Doctors can simulate treatment plans for ridge cap stones and otolith vertigo through the otolith resetting model 10 to improve the doctor's treatment success rate and treatment efficiency, and the treatment experience of the patients receiving treatment is better. For patients with otolith vertigo, the patient's head can wear the otolith resetting model 10 (the limiter 4 is located in the second position), and the doctor can observe the position of the otolith 2 in the semicircular canal 1 to determine the current position of the otoliths in the semicircular canal of the patient in a certain position (such as lying flat, lying on the side, semi-lying or sitting). The doctor can instruct the patient to change the position according to the observed position. After the patient changes the position, the otolith 2 will move in the semicircular canal 1. The doctor judges whether the otolith 2 moves toward the ampulla 12 according to the movement trajectory of the otolith 2 in the semicircular canal 1 to determine whether the patient's otolith is reset to the utricle (the utricle is connected to the ampulla in the inner ear labyrinth of vertebrates). Therefore, the doctor can visually observe the position of the otolith 2 of the otolith repositioning model 10 in the semicircular canal 1 to more easily determine the position of the patient's otoliths and more easily direct the patient to change to a suitable body position. The treatment success rate and treatment efficiency for otolith vertigo are high, and the patient's treatment experience is better.

[0082] Of course, the otolith repositioning model 10 can also be used for medical simulation purposes such as medical training or teaching demonstrations, which helps to improve the learning efficiency of medical beginners.

[0083] The material of the semicircular canal 1 can be a completely transparent material (e.g., the transparency is 90% to 100%), under which the doctor can intuitively observe the position of the otolith 2 in the semicircular canal 1. Of course, the material of the semicircular canal 1 can be a translucent material (e.g., the transparency is 50% to 75%), for example, the surface of the semicircular canal 1 is provided with a translucent coating, for example, the color of the translucent coating on the surface of the main body 11 is different from the color of the translucent coating on the surface of the ampulla 12, so that the user can distinguish the main body 11 from the ampulla 12.

[0084] The material of the guide member 3 may also have a certain degree of transparency to reduce the degree of visual obstruction of the guide member 3 to the otolith 2 , so that the user can observe the condition of the otolith 2 more intuitively.

[0085] Either the otolith 2 or the stopper 4 may include a magnetic body (commonly known as a magnet or a magnetite), and the other may include a magnetophilic metal. A magnetic body is a substance that can maintain residual magnetism and a magnetic field after being magnetized, and the magnetic body includes at least one element of iron, cobalt, and nickel. A magnetophilic metal is a substance that is not magnetized or is difficult to maintain residual magnetism and a magnetic field after being magnetized, but the magnetophilic metal can be magnetized by the magnetic field of the magnetic body, so that the magnetophilic metal and the magnetic body are magnetically attracted, and the magnetophilic metal includes at least one element of iron, cobalt, and nickel.

[0086] Of course, both the otolith 2 and the limiting member 4 may include magnetic bodies. After the two are magnetically attracted, the magnetic attraction between the two is greater, so that the otolith 2 can be more reliably limited in the second accommodating cavity 121.

[0087] The following content of this article is mainly described by taking "the otolith 2 includes a magnetophilic metal, and the limiter 4 includes a magnetic body" as an example.

[0088] Since the guide 3 and the limiting member 4 are movably connected, that is, the limiting member 4 is limited to the guide 3, when the user uses the otolith resetting model 10, the limiting member 4 is not easily lost, or the user does not need to separately save the limiting member 4, and the user's use experience is better. Secondly, the guide 3 has a guiding effect on the limiting member 4, so that the user can easily change the position of the limiting member 4 to the first position or the second position, the user's operation difficulty is low, and the user's use experience is better.

[0089] The movable connection between the guide member 3 and the stop member 4 may be a sliding connection, a rotating connection or a spiral connection. The following content of this article mainly describes the sliding connection between the guide member 3 and the stop member 4 as an example.

[0090] Optionally, see Figure 3-Figure 4 As shown, if the guide member 3 and the limit member 4 are slidably connected, this setting is convenient for the user to change the position of the limit member 4 relative to the guide member 3 by directly or indirectly moving the limit member 4 with a finger, the user's operation difficulty is low, and the user experience is better.

[0091] The sliding track of the limiting member 4 relative to the guiding member 3 may be in a straight line or an arc shape.

[0092] Optionally, see Figure 5 As shown, the guide member 3 includes a slide groove 31, and the slide groove 31 encloses a third accommodating cavity 31a. At least part of the structure of the limiting member 4 is located in the third accommodating cavity 31a. The limiting member 4 can slide relative to the slide groove 31 to the following position: Figure 3 The first position shown or Figure 4 In this setting, no matter the position limiter 4 slides relative to the slide slot 31 to the position shown in FIG. Figure 3 The first position shown or Figure 4In the second position shown, at least a portion of the structure of the limiting member 4 is always located in the slide groove 31, the limiting member 4 is not easily lost, or the user does not need to store the limiting member 4 separately, and the user's experience is better.

[0093] The first position may be one end of the slide slot 31 , and the second position may be the other end of the slide slot 31 .

[0094] In addition, the shape of the slide groove 31 can be a straight line, and the first position and the second position can be arranged opposite to each other on the slide groove 31 .

[0095] Furthermore, the third accommodating cavity 31 a may be communicated with the outside of the guiding member 3 , so that the user's fingers may directly or indirectly move the limiting member 4 .

[0096] In other embodiments (not shown in the figure), the limiting member 4 may include a slide groove (eg, T-shaped or dovetail-shaped), and the guiding member 3 may include a slide rail (eg, T-shaped or dovetail-shaped), and the slide rail and the slide groove may be slidably connected.

[0097] In other embodiments (not shown in the figures), the structure of the guide member 3 may include a rod structure, the limiting member 4 may be provided with a through hole, and the rod structure may be inserted into the through hole so that the guide member 3 is slidably connected to the limiting member 4.

[0098] The following content of this article is mainly described by taking “at least part of the structure of the limiting member 4 is located in the third accommodating cavity 31 a formed by the sliding groove 31 of the guiding member 3 ” as an example.

[0099] Optionally, see Figure 5 As shown, the inner surface 311 of the slide groove 31 can abut against the outer surface 41 of the limit member 4 to limit the limit member 4 from being separated from the third accommodating chamber 31a. Under this setting, the limit member 4 is not easily lost, or the user does not need to keep the limit member 4 separately, and the user experience is better.

[0100] The inner surface 311 of the slide groove 31 may be in the shape of an arc surface, and the outer surface 41 of the stopper 4 may be in the shape of an arc surface.

[0101] In addition, the structure of the limiting member 4 can be a columnar structure or a disc-shaped structure.

[0102] In other embodiments (not shown in the figures), the guide member 3 may include other limiting structures located outside the slide groove 31, and the limiting structure may abut against the outer surface 41 of the limiting member 4 to limit the limiting member 4 from being separated from the third accommodating cavity 31a.

[0103] Optionally, see Figure 5As shown, the otolith repositioning model 10 also includes a driving member 5, at least part of the structure of the driving member 5 is located outside the third accommodating cavity 31a, the driving member 5 is connected to the limiting member 4, and the user can indirectly drive the limiting member 4 to slide to the first position or the second position through the driving member 5. Under this setting, the user's operation difficulty is low and the user's experience is better.

[0104] The structure of the driving member 5 may be a rod-shaped structure, a plate-shaped structure or a disc-shaped structure.

[0105] In other embodiments, the otolith repositioning model 10 may not include the driving member 5, and the user may directly slide the limiting member 4 to the first position or the second position.

[0106] Optionally, see Figure 6 As shown, the main body 11 includes a first connection portion 112 and a second connection portion 113 arranged oppositely, the ampulla 12 includes a third connection portion 122 and a fourth connection portion 123 arranged oppositely, the first connection portion 112 is connected to the third connection portion 122, and the second connection portion 113 is connected to the fourth connection portion 123. Compared with the otolith repositioning model in the prior art, the otolith repositioning model 10 of the embodiment of the present application has a simpler structure, a simpler manufacturing process, and a higher degree of manufacturability.

[0107] Optionally, see Figure 6 As shown, the first accommodating chamber 111 and the second accommodating chamber 121 are connected to form an annular passage 1a, or in other words, the first accommodating chamber 111 and the second accommodating chamber 121 can be bidirectionally connected, that is, the space corresponding to the first connection portion 112 in the first accommodating chamber 111 is connected to the space corresponding to the third connection portion 122 in the second accommodating chamber 121, and the space corresponding to the second connection portion 113 in the first accommodating chamber 111 is connected to the space corresponding to the fourth connection portion 123 in the second accommodating chamber 121. This arrangement enables the movement direction of the otolith 2 to only include the direction from the first accommodating chamber 111 to the second accommodating chamber 121 and the direction from the second accommodating chamber 121 to the first accommodating chamber 111, that is, the movement of the otolith 2 from the first accommodating chamber 111 to the second accommodating chamber 121 and the movement from the second accommodating chamber 121 to the first accommodating chamber 111 can be more easily simulated, thereby more easily simulating otolith vertigo.

[0108] In other embodiments (not shown in the figures), the first accommodating chamber 111 and the second accommodating chamber 121 can be connected in one direction, and only the space in the first accommodating chamber 111 corresponding to the first connecting portion 112 is connected with the space in the second accommodating chamber 121 corresponding to the third connecting portion 122, or, only the space in the first accommodating chamber 111 corresponding to the second connecting portion 113 is connected with the space in the second accommodating chamber 121 corresponding to the fourth connecting portion 123.

[0109] The following content of this article is mainly described by taking “the first accommodating chamber 111 and the second accommodating chamber 121 connected to form an annular passage 1a” as an example.

[0110] Optionally, see Figure 7 As shown, the fourth connection part 123 includes a recessed structure 1231 recessed into the second accommodating cavity 121, the connection end 1231a of the recessed structure 1231 is connected to the second connection part 113, and the inner wall 1231b of the recessed structure 1231 and the main inner wall 124 of the ampulla 12 are enclosed to form an annular groove 125. Under this setting, when the patient changes his position, the otolith 2 can move from the first accommodating cavity 111 to the second accommodating cavity 121 and fall into the space enclosed by the annular groove 125 along the direction of the hollow triangle arrow, for example Figure 7 The structure indicated by the dotted line in the middle circle is used to represent the otolith 2 that falls into the space enclosed by the annular groove 125. The doctor can judge that the patient's otolith has passed the ampulla and returned to the utricle based on the otolith 2 located in the space enclosed by the annular groove 125, and can thus instruct the patient to stop changing body position.

[0111] Among them, the inner diameter D1 of the main body 11 is smaller than the inner diameter D2 of the ampulla 12. In other words, the diameter D1 of the first accommodating cavity 111 is smaller than the inner diameter D2 of the second accommodating cavity 121. Under this setting, the semicircular canals of vertebrates can be simulated more realistically, and users can easily distinguish the main body 11 and the ampulla 12.

[0112] In addition, the connection end 1231a may be an end of the recessed structure 1231 close to the third connection portion 122, or the connection end 1231a may be an end of the recessed structure 1231 far from the third connection portion 122. The following content of this article is mainly described by taking "the connection end 1231a is an end of the recessed structure 1231 close to the third connection portion 122" as an example.

[0113] Optionally, see Figure 7As shown, there is a set minimum distance L between the connecting end 1231a of the recessed structure 1231 and the main inner wall 124 of the ampulla 12, and the otolith 2 has a set radius R, satisfying L>R. Under this setting, the probability that the otolith 2 enters the second accommodating cavity 121 from the first accommodating cavity 111 through the first connecting portion 112 and the third connecting portion 122 and falls into the space enclosed by the annular groove 125 is relatively high, that is, the probability that the otolith 2 enters the second accommodating cavity 121 from the first accommodating cavity 111 through the first connecting portion 112 and the third connecting portion 122 and then re-enters the first accommodating cavity 111 through the fourth connecting portion 123 and the second connecting portion 113 is relatively small, so that the doctor can more easily judge that the patient's otolith has passed the ampulla and reset to the utricle based on the otolith 2 located in the space enclosed by the annular groove 125, so that the patient can be more easily instructed to pause and change body position. Secondly, compared with the otolith repositioning model in the prior art, which has the problem that the otoliths are not easy to enter the main body from the utricle via the ampulla, the otolith repositioning model 10 of the embodiment of the present application also has the following advantages: the probability that the otolith 2 enters the space of the first accommodating cavity 111 from the second accommodating cavity 121 along the direction of the black solid triangle arrow through the third connecting part 122 and the first connecting part 112 is relatively high, so that the otolith 2 located in the space enclosed by the annular groove 125 can more easily re-enter the first accommodating cavity 111 along the direction of the black solid triangle arrow, so that the user can more easily reuse the otolith repositioning model 10 to simulate otolith vertigo.

[0114] Optionally, the otolith repositioning model 10 includes at least two semicircular canals 1, and the first accommodating cavity 111 and the second accommodating cavity 121 of any semicircular canal 1 are connected to form a passage 1a, and the passage 1a of any semicircular canal 1 is relatively independent from the passages 1a of other semicircular canals 1. Accordingly, the otolith repositioning model 10 includes at least two otoliths 2. Under this setting, the movement of the otolith 2 located in the passage 1a of any semicircular canal 1 does not interfere with the movement of the otolith 2 located in the passage 1a of other semicircular canals 1, and the user experience is better.

[0115] Please refer to Figure 3-Figure 4 As shown, the otolith repositioning model 10 may include three semicircular canals 1, the first semicircular canal 1 may be used to simulate the superior semicircular canal of vertebrates, the second semicircular canal 1 may be used to simulate the posterior semicircular canal of vertebrates, and the third semicircular canal 1 may be used to simulate the horizontal semicircular canal of vertebrates. Accordingly, the otolith repositioning model 10 may include three otoliths 2, the first otolith 2 may be used to simulate the otolith located in the superior semicircular canal, the second otolith 2 may be used to simulate the otolith located in the posterior semicircular canal, and the third otolith 2 may be used to simulate the otolith located in the horizontal semicircular canal.

[0116] Optionally, the otolith 2 is spherical in shape, and the otolith 2 in this shape can roll more easily in the passage 1 a.

[0117] In other embodiments (not shown in the figures), the shape of the otolith 2 may also be an ellipsoid or other shape with a curved outer surface.

[0118] Optionally, see Figure 1-Figure 4 As shown, the otolith repositioning model 10 further includes an utricle 6, which is connected to the semicircular canal 1, and / or the utricle 6 is connected to the guide 3. The utricle 6 is used to simulate the structure for accommodating otoliths in the inner ear membranous labyrinth of vertebrates, so that users can understand the position of the real utricle relative to the semicircular canal.

[0119] The utricle 6 is not provided with a pipeline that can communicate with the first accommodating cavity 111 and the second accommodating cavity 121 , and the color of at least part of the structure of the utricle 6 is different from that of the semicircular canal 1 , so that users can clearly distinguish the semicircular canal 1 from the utricle 6 .

[0120] In addition, the material of the utricle 6 may also have a certain degree of transparency to reduce the degree of visual obstruction of the utricle 6 to the otolith 2 , making it easier for the user to observe the condition of the otolith 2 more intuitively.

[0121] Optionally, the semicircular canal 1 and the guide member 3 can be integrally formed. If the semicircular canal 1 and the guide member 3 are integrally formed, the integrally formed semicircular canal 1 and the guide member 3 can be prepared by a three-dimensional printing process, wherein the three-dimensional printing process includes but is 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 three-dimensional printing or additive manufacturing technologies known in the art, which are not limited here.

[0122] Optionally, the semicircular canal 1 and the utricle 6 can be integrally formed, and the integral forming process can be a three-dimensional printing process.

[0123] In other embodiments, the semicircular canal 1 and the guide 3 may be detachably connected, and the semicircular canal 1 and the utricle 6 may be detachably connected.

[0124] Optionally, see Figure 8As shown, the otolith reset model 10 also includes a connector 7. At least one of the semicircular canals 1, the guide 3 and the utricle 6 is connected to the connector 7, and the connector 7 is used to be detachably connected to a head mounting member (not shown). When the head mounting member is installed on the user's head, the otolith reset model 10 can follow the user's head movement, thereby more easily simulating the position and movement trajectory of the user's otoliths. The mode in which the connector 7 is detachably connected to the head mounting member is convenient for the user to operate the otolith reset model 10 alone with his hand, so that the otolith reset model 10 is quickly adjusted to the desired state, and then the otolith reset model 10 is installed to the head mounting member already installed on the user's head, and the user's experience is better. Secondly, the otolith reset model 10 separated from the head mounting member can be used as a model by the user alone to give a speech or teach, and the user's experience is better when there is no interference from the head mounting member.

[0125] The detachable connection between the connector 7 and the head mounting member includes at least one of a sleeve connection, a snap-on connection, a magnetic connection, a riveted connection, a bolt connection, and an adhesive connection. The detachable connection mentioned in the following content of this article may also include at least one of a sleeve connection, a snap-on connection, a magnetic connection, a riveted connection, a bolt connection, and an adhesive connection, which will not be described in detail in the following content.

[0126] In other embodiments, the connecting member 7 and part of the structure of the head mounting member may be integrally formed.

[0127] In other embodiments, the connector 7 can also be detachably connected to the bracket (not shown in the figure) so that the otolith repositioning model 10 can be placed on the stage as a static model through the bracket, thereby reducing the weight on the user's hands, making it easier for the user to give lectures or teach, and providing a better user experience.

[0128] In a second aspect, the present application provides an otolith repositioning device, please refer to Fig. 9 As shown, the otolith repositioning device may include a head mounting member 20 and the otolith repositioning model 10 described above. The head mounting member 20 is detachably connected to the otolith repositioning model 10, and the head mounting member 20 is used to be mounted on a Fig.10 The user's (eg, patient or doctor's) head 30 is shown to fix the position of the otolith repositioning model 10 relative to the head 30. The otolith repositioning device of the embodiment of the present application includes the technical effects of the otolith repositioning model 10 in the above content, which will not be repeated here.

[0129] Optionally, see Fig.10As shown, the head mounting member 20 includes a connected strap 201 and an adapter 202, the strap 201 is used to be tied to the user's head 30, and the adapter 202 is detachably connected to the otolith reduction model 10. The relevant effects have been described above and will not be repeated here.

[0130] The strap 201 is mainly used to fix the chin, top of the head and back of the head 30 .

[0131] In addition, please refer to Figure 11-Figure 12 As shown, the adapter 202 may include a body 2021, the body 2021 includes a slot 2021a, the body 2021 is further provided with a through hole 2021b, and the space enclosed by the slot 2021a is connected to the through hole 2021b. Figure 8 As shown, the connector 7 of the otolith repositioning model 10 may include a buckle 71. A partial structure of the connector 7 may be inserted into the space enclosed by the slot 2021a along the direction X, and accordingly, the buckle 71 may also enter the space enclosed by the slot 2021a along the direction X, and a partial structure of the buckle 71 may enter the through hole 2021b, and a side wall structure in the body 2021 for enclosing the through hole 2021b may abut against the buckle 71 to limit the buckle 71 from being disengaged from the slot 2021a in the direction opposite to the direction X, thereby making the otolith repositioning model 10 detachably connected to the adapter 202. The user can apply external force to the buckle 71 to make the buckle 71 disengage from the through hole 2021b and completely enter the space enclosed by the slot 2021a. The side wall structure in the main body 2021 used to enclose the through hole 2021b does not abut against the buckle 71. The buckle 71 can disengage from the slot 2021a in the direction opposite to the direction X, thereby separating the otolith reduction model 10 from the adapter 202.

[0132] Furthermore, please refer to Fig.13 As shown, the buckle 71 structure can be an elastic sheet. When the buckle 71 enters the space enclosed by the slot 2021a along the direction X, the buckle 71 is deformed along the direction A by the force of the slot 2021a, and then part of the structure of the buckle 71 is reset along the direction B to enter the through hole 2021b, so that the side wall structure of the body 2021 used to enclose the through hole 2021b abuts against the buckle 71, thereby limiting the buckle 71 from escaping from the slot 2021a in the direction opposite to the direction X. When the user applies a force to the buckle 71 to deform the buckle 71 along the direction A, the buckle 71 can detach from the through hole 2021b and completely enter the space enclosed by the slot 2021a, and the side wall structure of the body 2021 used to enclose the through hole 2021b does not abut against the buckle 71, so that the buckle 71 can detach from the slot 2021a in the direction opposite to the direction X.

[0133] In other embodiments (not shown in the figures), the structure of the buckle 71 can be other structures with deformation function such as elastic button components.

[0134] In other embodiments (not shown in the figure), the otolith repositioning model 10 can be directly and detachably connected to the bandage 201. For example, the bandage 201 can be directly tied to the connecting piece 7 of the otolith repositioning model 10.

[0135] In other embodiments (not shown in the figures), the head mounting member 20 may include a helmet, and the otolith repositioning model 10 is detachably connected to the helmet, so that the helmet can be worn on the user's head.

[0136] In other embodiments (not shown in the figures), the head mounting member 20 may include an ear hanging member, and the structure of the ear hanging member includes an arc structure so that the ear hanging member can be hung on the ear of the user's head.

[0137] Optionally, the strap 201 is detachably connected to the adapter 202, and the adapter 202 can be in at least two positions relative to the strap 201. Correspondingly, the otolith repositioning model 10 connected to the adapter 202 can also be in at least two positions relative to the strap 201. This arrangement makes it easy for the user to adjust the otolith repositioning model 10 to a position equivalent to the strap 201, so that the otolith repositioning model 10 can be close to the user's inner ear labyrinth, so that the otolith 2 of the otolith repositioning model 10 can more easily and realistically reflect the condition of the user's otoliths, and the user has a better user experience.

[0138] Please refer to Fig.12 As shown, the adapter 202 may include a first clamping portion 2022 , which is connected to the body 2021 . The first clamping portion 2022 and the body 2021 may clamp the strap 201 . This arrangement facilitates the user to adjust the position of the adapter 202 relative to the strap 201 .

[0139] In addition, please refer to Fig.12 As shown, under the condition that the number of the strap 201 is at least two, the adapter 202 may further include a second clamping portion 2023, and the second clamping portion 2023 is connected to the body 2021. The first clamping portion 2022 and the body 2021 may clamp one section of the strap 201, and the second clamping portion 2023 and the body 2021 may clamp the other section of the strap 201. Under this setting, the connection reliability between the strap 201 and the adapter 202 is relatively high.

[0140] Furthermore, please refer to Fig.12As shown, the adapter 202 may further include at least a plurality of protrusions 2024, a side of the first clamping portion 2022 facing the main body 2021 may be provided with a protrusion 2024, a side of the main body 2021 facing the first clamping portion 2022 may also be provided with a protrusion 2024, the surface of the protrusion 2024 may be an arc surface, and the protrusion 2024 is used to increase the friction between the adapter 202 and the strap 201, so as to make the connection reliability between the strap 201 and the adapter 202 higher.

[0141] Of course, a side of the second clamping portion 2023 facing the main body 2021 may be provided with a protrusion 2024, and a side of the main body 2021 facing the second clamping portion 2023 may be provided with a protrusion 2024, so as to make the connection reliability between the strap 201 and the adapter 202 higher.

[0142] Optionally, the strap 201 is an adjustable strap 201, so that it can be adapted to users of different body shapes. The strap 201 can specifically be a nylon hook and loop strap, a buckle strap or a snap strap.

[0143] Optionally, the preparation process of the adapter 202 can be a three-dimensional printing process, wherein the exemplary three-dimensional printing processes 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 three-dimensional printing or additive manufacturing technologies known in the art, which are not limited here. In other embodiments, the preparation process of the adapter 202 can be a mold injection molding process.
