Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a vertigo diagnosis and treatment device. Background Technology

[0002] The vestibular system is the primary organ for balance in the human body. The semicircular canals, as key structures within the vestibular system that sense changes in head position, play an irreplaceable role. The semicircular canals are divided into the horizontal, superior, and posterior semicircular canals. These three canals lie in mutually perpendicular planes and sense dynamic changes in head position within different planes. When a person's posture changes, the intensity of stimulation received by each semicircular canal varies depending on the direction of the change. If an imbalance in the stimulation received by the two semicircular canals occurs, nystagmus is triggered, with the nystagmus directed towards the side receiving stronger stimulation. Based on this scientific principle, targeted stimulation of the corresponding semicircular canals can be achieved by performing accelerated or decelerated rotational manipulations on different planes of the semicircular canals. During this process, doctors can comprehensively and accurately assess the balance of bilateral vestibular function and the functional status of each semicircular canal through detailed examination of the nystagmus. Especially in treating positional vertigo caused by dislodged otoliths, using specific body postures to reposition the dislodged otoliths can effectively cure the vertigo symptoms of the vast majority of patients clinically.

[0003] Vertigo diagnostic and treatment equipment, as a core medical device for stabilizing the human body, conducting semicircular canal function tests, and further evaluating vestibular function, plays a crucial role in the diagnosis and treatment of vertigo. Most existing vertigo diagnostic and treatment equipment uses a gear and large gear ring transmission method, designed to precisely control the rotation of the swivel chair. However, this large gear ring swivel chair transmission structure has many insurmountable drawbacks. The large gear ring, as an ultra-large precision component, has extremely high requirements for machining accuracy, deformation control, and assembly precision; otherwise, it will not only generate significant noise but also affect the meshing accuracy of the gear and large gear ring. Furthermore, the large gear ring swivel chair is limited by the machining deformation and tooth strength of the large gear ring, requiring the use of steel-like materials for the large gear ring. This results in a large weight and rotational inertia, necessitating a high-power motor drive, leading to high energy consumption. Moreover, the large weight and size of the large gear ring make transportation and installation difficult. Utility Model Content

[0004] The purpose of this application is to provide a vertigo diagnosis and treatment device that not only meets the requirements for accurate positioning of rotating components but also reduces the difficulty of processing and installation. More preferably, the vertigo diagnosis and treatment device of this application can reduce the weight and inertia of the rotating structure, thereby reducing the power of the drive motor.

[0005] The technical solution provided in this application is as follows:

[0011] The second drive mechanism is used to drive the rotating part to rotate around the horizontal axis.

[0012] The rotating component has a segmented splicing structure, specifically including:

[0013] The rotating component is formed by splicing together several arc-shaped segments, and / or;

[0014] Several arc-shaped splicing parts are installed on the rotating part.

[0015] In some embodiments, the arc-shaped splicing component is an arc-shaped toothed segment, which is continuously or intermittently distributed along the circumferential direction of the rotating component.

[0016] In some embodiments, the second drive mechanism includes a drive gear mounted on a frame; the drive gear directly meshes with the arc-shaped tooth segment, or is driven to the arc-shaped tooth segment via a toothed transmission element (such as a synchronous toothed belt).

[0017] In some embodiments, the arc-shaped splicing component is an arc-shaped guide rail, which is installed on the outer or inner circumference of the rotating component and continuously spliced ​​along the circumferential direction to form an annular guide rail.

[0018] In some embodiments, the arc segments are detachably connected; and / or the arc splice and the rotating component are detachably connected to facilitate transportation, installation and maintenance.

[0019] In some embodiments, the arc-shaped tooth segments are spaced apart along the outer periphery of the rotating component, and an arc-shaped transition segment is provided between adjacent arc-shaped tooth segments. The outer circumferential surface of the arc-shaped transition segment is not provided with a tooth structure. The arc-shaped transition segment is fixed to the rotating component and together with the arc-shaped tooth segments, forms a circumference concentric with the rotating component.

[0020] In some embodiments, the rotating member has a protruding positioning step for positioning the arc-shaped splice, and the arc-shaped splice abuts against the positioning step.

[0021] In some embodiments, the circumferential surface of the rotating component is provided with a mounting groove, and the arc-shaped splicing component is fixedly installed in the mounting groove.

[0022] In some embodiments, the vertigo treatment device further includes multiple sets of guide wheels, which are mounted on the frame and evenly distributed around the rotating component along the circumference of the rotating component; the multiple sets of guide wheels contact the rotating component respectively to guide the rotating component and ensure that it rotates stably around a predetermined horizontal axis.

[0023] In some embodiments, the support mechanism includes a support member and a seat; wherein the support member is connected to the rotating member, the seat is mounted on the support member, and a horizontal adjustment mechanism is provided between the seat and the support member. This horizontal adjustment mechanism allows adjustment of the distance between the subject and the vertical axis, thereby adjusting the magnitude of the centrifugal force during rotation around the vertical axis to meet the requirements of the corresponding vestibular function test.

[0024] In some embodiments, the vertigo diagnosis and treatment device further includes a rotary electrical connection device, which is installed between the rotating component and the frame, with its stationary part connected to the frame and its rotating part coaxially connected to the rotating component, for transmitting electrical energy and / or signals during the rotation of the rotating component.

[0025] In some embodiments, a rotary electrical connection device is installed between the rotating member and the frame, wherein the rotating portion of the rotary electrical connection device is coaxially connected to the rotating member, and the stationary portion is connected to the frame via a mounting structure including an elastic element.

[0041] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application can also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0042] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0043] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0044] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0045] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; or they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) are relative rather than absolute when describing the structure and movement of the various components, and are not intended to limit the direction of the product during actual use.

[0047] Furthermore, in the description of this application, ordinal numbers, such as "first" and "second," are used only to distinguish related objects and should not be construed as indicating or implying the relative importance or order between related objects.

[0048] One embodiment of this application provides a vertigo diagnosis and treatment device, such as... Figure 1 As shown, it includes a frame 100, a rotating component 200, a load-bearing mechanism, a first drive mechanism, and a second drive mechanism;

[0049] The frame 100 serves as the basic support structure for the equipment, forming a frame-like structure for mounting the load-bearing and drive mechanisms. The frame 100 can be constructed from metal profiles or welded materials, providing excellent stability and load-bearing capacity, ensuring strength and stability. Multiple support feet can be installed at the bottom of the frame 100 to balance the entire swivel chair and prevent wobbling. Casters can also be installed at the bottom of the support feet to facilitate the movement of the entire swivel chair.

[0050] The rotating component 200 has a ring-shaped or disc-shaped structure and is rotatably mounted on the frame 100. It can rotate around a horizontal axis 20 passing through its center under the drive of a second drive mechanism. Specifically, the horizontal axis 20 is the central axis passing through the center of the rotating component 200 and perpendicular to its ring / disc surface, or it can be a transverse axis passing through the center of the rotating component 200 (rotation mode is flipping). The horizontal axis 20 may vary depending on the rotation mode of the rotating component 200. In this embodiment, the cross-section of the rotating component 200 can be hollow or honeycomb-shaped. When the cross-section of the rotating component 200 is hollow, reinforcing ribs can be provided inside the rotating component 200 to improve its rigidity and strength. This not only ensures that the overall rigidity and strength of the rotating component 200 meet the requirements but also reduces its weight, thereby reducing its moment of inertia and the required power of the drive motor, thus lowering energy consumption. The rotating component 200 can be a one-piece structure. It can also be a combined structure formed by splicing multiple arc segments, with each arc segment fixed to each other as a whole by screwing, welding, plugging or other connection methods.

[0051] A support mechanism is mounted on the rotating component 200 to support the patient. The 300 includes a support member 310 and a seat 320, with the seat 320 mounted on the support member 310 and connected to the rotating component 200. To improve the rotational stability of the seat 320, it can be connected to the frame 100 via components such as a shaft and bearings, enabling stable rotation of the seat 320. The shaft of the seat 320 coincides with the center of the rotating component 200. Furthermore, the vertigo treatment device also includes a seatbelt system and a head restraint device, allowing the patient to be reliably secured to the seat 320. In another embodiment, a horizontal adjustment mechanism is provided between the seat 320 and the support member 310. This mechanism allows the seat 320 to move horizontally relative to the support member 310, thereby adjusting the distance between the seat 320 and the vertical axis 10.

[0052] For example, when an eccentricity test is required, the seat 320 can be adjusted to a position offset from the vertical axis 10 using a horizontal adjustment mechanism and then fixed. When the seat 320 subsequently rotates around the vertical axis 10, the patient will experience a corresponding centrifugal force due to the offset between the center of the seat 320 and the axis of rotation (vertical axis 10). At this time, the patient's left and right ears will experience different magnitudes of centrifugal force due to their different positions, thus creating asymmetrical vestibular stimulation. This method can simulate and detect the balance response and vestibular system function of subjects under asymmetrical acceleration environments, and is particularly suitable for eccentricity rotation tests in the diagnosis and treatment of vertigo.

[0053] Specifically, the leveling mechanism can be implemented in various ways, including but not limited to:

[0054] Slide rail and lead screw transmission mechanism: The seat 320 is driven to slide horizontally along the slide rail by the lead screw, and the lead screw is used to keep it fixed by self-locking;

[0055] Rack and pinion transmission mechanism: The gear meshes with the rack to drive the seat 320 to move in the horizontal direction, and can be fixed by the meshing relationship after the drive stops;

[0056] Electric push rod mechanism: The seat 320 level position is adjusted by extending and retracting the push rod, and the push rod remains locked after the action stops;

[0057] Mechanical locking slide rail mechanism: The position adjustment and fixation of seat 320 are achieved by manual release and locking.

[0058] Through the different structural forms mentioned above, the position of the seat 320 can be adjusted and fixed, and the relative distance between the patient and the vertical axis 10 can be flexibly selected in different test modes to obtain the required centrifugal force effect.

[0059] The first drive mechanism is mounted on the frame 100 or the support mechanism to drive the support mechanism to rotate horizontally around the vertical axis 10, thereby enabling the seat 320 to rotate and thus quickly position or turn the patient in different positions. The vertical axis 10 is perpendicular to the horizontal axis 20, and the vertical axis 10 refers to the axis parallel to the direction of gravity in the normal installation state of the equipment.

[0060] The second drive mechanism is used to drive the rotating component 200 to rotate around the horizontal axis 20, so that the patient rotates synchronously. For example, the second drive mechanism includes Figure 1 The drive gear 400 drives the rotating component 200 to rotate via the toothed transmission component 500.

[0061] When using the vertigo diagnosis and treatment device of this embodiment, the patient sits on the seat 320 and fastens the seat belt on the seat 320. The second drive mechanism is activated, and the second drive mechanism drives the rotating component 200 to rotate synchronously. The rotation of the rotating component 200 is transmitted to the patient through the seat 320, thereby realizing the detection or treatment of the patient. During the rotation of the seat 320 driven by the rotating component 200, the seat 320 can also be driven to rotate around the vertical axis 10 through the first drive mechanism, thereby realizing the rotation of the seat 320 in three-dimensional space.

[0062] In this embodiment, through the coordinated control of the first and second drive mechanisms, the patient can perform multi-degree-of-freedom rotational operations in three-dimensional space, satisfying different vestibular function tests and thus achieving the purpose of vertigo diagnosis and treatment. By controlling the rotational speed and angle of the motors in the first and second drive mechanisms, the rotational speed and position of the seat 320 can be adjusted to meet the treatment needs of different patients.

[0063] In this embodiment, the rotating component 200 adopts a segmented splicing structure. Depending on the implementation method, the rotating component 200 itself can be formed by splicing several arc-shaped segments, or several arc-shaped splicing components can be installed on the rotating component 200. Compared with the integrated structure of the large gear ring in the prior art, the rotating component adopts a splicing structure or a structure with arc-shaped splicing components installed on the rotating component. This not only reduces the area for high-precision machining, significantly reduces the machining difficulty, and lowers the requirements for machining equipment and processes, thereby significantly reducing machining costs, but also reduces the weight and inertia of the rotating component, and the power required for the drive motor is also reduced.

[0064] In one embodiment, the rotating component 200 is formed by splicing arc-shaped segments: the rotating component 200 is formed by splicing several arc-shaped segments, which can be annular arc segments (ring splicing parts) or fan-shaped segments (disc splicing parts); adjacent arc-shaped segments are fixedly connected by structures such as bolts and locating pins, and after splicing, a complete ring or disk is formed. Figure 2 and Figure 3 As shown, the rotating component 200 of the ring is composed of two or more annular arc segments 201 joined together. Adjacent annular arc segments 201 can be fixedly connected by fixing devices such as positioning pins 202 to form a stable rotor. Preferably, the arc edges of the arc segments have toothed structures, and adjacent arc segments are continuously distributed in the circumferential direction after being joined together, forming a rotating component 200 similar to a toothed ring. The rotating component 200 meshes with the drive gear 400 or other toothed transmission components, thereby driving the rotating component 200 to rotate synchronously. The arc edges of the arc segments can be the outer arc edge, inner arc edge, or lateral circumferential surface of the arc segment. When the arc segments do not have toothed structures, the rotating component 200 can be driven to rotate by friction or by a dual-guide rail drive.

[0065] In another embodiment, several arc-shaped splicing components are installed on the rotating component 200. The arc-shaped splicing components are arc-shaped guide rails 610. The arc-shaped guide rails 610 can be installed along the circumference of the rotating component 200. Specifically, the installation position is, for example, the outer circumference, inner circumference, or end face of the rotating component 200.

[0066] For example, when installed on the periphery, such as Figure 4 As shown, a segmented arc-shaped guide rail 610 is installed on the outer periphery of the rotating component 200. The arc-shaped guide rail 610 is provided with protrusions or grooves arranged in the circumferential direction. Preferably, a number of guide wheels 800 are arranged on the frame 100 along the circumferential direction of the rotating component. The guide wheels 800 are provided with grooves or protrusions that are adapted to the shape of the arc-shaped guide rail 610 to cooperate with the operation of the arc-shaped guide rail 610.

[0067] For example, when installed on the inner circumference, such as Figure 5 As shown (the supporting mechanism is not shown), several arc-shaped guide rails 610 are installed on the inner circumference of the rotating component 200. These arc-shaped guide rails 610 are spliced ​​to form a ring guide rail. Furthermore, several guide wheels 800 are provided on the inner circumference of the rotating component 200. The guide wheels 800 cooperate with the arc-shaped guide rails 610 to improve rotational stability. Thus, the equipment can select the corresponding guide rail arrangement scheme according to the specific design structure.

[0068] The aforementioned arc-shaped guide rail 610 (such as an outer arc-shaped guide rail or an inner arc-shaped guide rail) is an arc-shaped component, and its track surface is a circular arc trajectory. Multiple arc-shaped guide rails 610 are continuously spliced ​​along the circumferential direction to form a ring guide rail. During splicing, it can be fixed by means of screws, pins or positioning grooves to ensure that the guide rail trajectory is continuous and smooth.

[0069] The aforementioned spliced ​​ring guide rail, in conjunction with the guide wheel 800, serves to share the radial centrifugal force generated by the bearing mechanism during rotation when the rotating component 200 rotates, ensuring that the bearing mechanism does not deviate radially or axially relative to the track, thus playing a guiding, limiting, and stabilizing role.

[0070] Specifically, if an arc-shaped guide rail 610 is installed on the inner or outer circumference of the rotating component 200, the installation position of the second drive mechanism should be offset from the guide rail formed by splicing the arc-shaped guide rail 610. The following are some example drive schemes:

[0071] When the outer periphery of the rotating component 200 is provided with an annular guide rail formed by splicing arc-shaped guide rails 610, the second drive mechanism is preferably installed on the end face of the rotating component 200. Specifically, a gear ring is provided on the end face of the rotating component 200, and the second drive mechanism includes a drive motor and a pinion gear meshing with the gear ring. The drive motor is fixedly installed on the frame 100, thereby driving the rotating component 200 to rotate around the horizontal axis 20 through gear meshing.

[0072] When the inner circumference of the rotating component 200 is provided with an annular guide rail formed by splicing arc-shaped guide rails 610, the guide rail is used to guide and limit the rotation of the mechanism. To enable the rotating component 200 to rotate around a central axis passing through its center and perpendicular to the ring / disc surface, a slewing bearing is provided at the center of the rotating component 200. One side of the slewing bearing is fixed to the frame 100, and the other side is connected to the rotating component 200. The second drive mechanism includes a drive motor and a reducer. Its output end meshes with the drive gear ring of the slewing bearing, or is connected to the rotating ring of the slewing bearing via a coupling, thereby driving the rotating component 200 to rotate around the central axis. The annular guide rail and the second drive mechanism are arranged in layers in the axial direction and do not interfere with each other.

[0073] In other embodiments, the end face of the rotating member 200 is provided with a drive gear ring (or synchronous belt gear ring / friction ring), and the second drive mechanism is fixed to the frame 100. The pinion (or pulley / friction wheel) at its output end meshes / contacts with the end face drive ring to input a rotational torque about the central axis to the rotating member 200. The annular guide rail on the inner circumference is located at a different axial position from the end face drive gear ring to achieve decoupling of the driving and guiding functions.

[0074] Furthermore, a toothed ring or friction ring is provided on the outer circle of the rotating part 200, and the second drive mechanism drives the rotation of the rotating part 200 by a drive wheel that meshes / presses with it; to improve stability, multiple drive / support wheels can be arranged circumferentially and preloaded.

[0075] Preferably, adjacent arc segments are detachably connected; and / or, the arc splice and the rotating part 200 are detachably connected to facilitate subsequent installation and maintenance.

[0076] In yet another embodiment, such as Figure 6 As shown, several arc-shaped splicing components are installed on the rotating component 200. These arc-shaped splicing components are arc-shaped toothed segments 620, which are part of a circular ring. After the arc-shaped toothed segments 620 are installed on the rotating component 200, their centers coincide with the center of the rotating component 200. The arc-shaped toothed segments 620 are toothed arc-shaped components with a toothed structure for meshing. The arc-shaped toothed segments 620 can be installed on the inner circumference, outer circumference, or lateral circumferential surface of the integral rotating component 200, forming a partial or complete toothed ring. The length of the arc-shaped toothed segments 620 can be designed according to actual needs; however, it is necessary to ensure that the arc-shaped toothed segments 620 remain meshed with the toothed transmission component 500 during rotation. Figure 6 As shown, an arc-shaped tooth segment 620 is provided on the inner circumference of the rotating component 200, and several arc-shaped tooth segments 620 installed on the inner circumference of the rotating component 200 form an internal tooth ring concentric with the rotating component 200. Figure 6In this design, the rotating component 200 is a single, integral circular ring structure, which offers better stability. Of course, the rotating component 200 can also be a spliced ​​structure, as in the aforementioned scheme where it is constructed by splicing arc-shaped segments; this is not a limitation here.

[0077] The number of arc-shaped tooth segments 620 is several (two or more), which can be continuously arranged along the circumference of the rotating part 200 to form a large tooth ring. The arc-shaped tooth segments 620 are fixed by bolts or plug-in structures, and locating pins, locating steps or mating surfaces are provided at the connection to ensure positioning accuracy and tooth pitch continuity.

[0078] Of course, the arc-shaped tooth segments 620 can also be spaced along the circumference of the rotating part 200. For example, two arc-shaped tooth segments 620 can be symmetrically installed on the rotating part 200, or multiple arc-shaped tooth segments 620 can be spaced apart.

[0079] In this implementation, the second drive mechanism includes a drive gear 400 mounted on a frame 100. A motor is also mounted on the frame 100. The drive gear 400 is driven by the motor and directly meshes with the arc-shaped tooth segment 620. The tooth profile of the drive gear 400 matches the tooth profile of the toothed transmission component 500, ensuring stable meshing between the drive gear 400 and the toothed transmission component 500, thus ensuring stability and reliability during transmission. Alternatively, the drive gear 400 can indirectly drive the arc-shaped tooth segment 620 through a toothed transmission component 500 such as a toothed belt / chain. When the drive gear 400 rotates, it drives the continuous or discontinuous toothed ring formed by the splicing of the arc-shaped tooth segments 620 to rotate, thereby driving the rotating component 200 to rotate around the horizontal axis 20. By using several arc-shaped tooth segments 620 mounted on the rotating component 200, a large-diameter toothed ring can be formed, avoiding the difficulties of overall machining, reducing manufacturing costs, and ensuring meshing accuracy. In addition, the use of aluminum alloy for the arc-shaped tooth segment 620 can significantly reduce the weight of the rotor (rotating part) and reduce the power of the motor.

[0080] In this embodiment, the rotational speed ratio between the drive gear 400 and the arc-shaped tooth segment 620 is constant. By adjusting the rotational speed and angle of the drive gear 400, the position and speed of the rotating component 200 can be precisely controlled, meeting the functional requirements of the vertigo treatment device for accurate positional fixation and improving the treatment effect. By designing the rotating component 200 and the arc-shaped tooth segment 620 separately, compared with the large gear ring structure in the prior art, this solution can reduce the processing and material requirements of the rotating component 200. The rotating component 200 can be made of more common and economical materials, which not only saves production costs but also reduces the weight and inertia of the rotating component 200, thus reducing the power of the required drive motor and reducing energy consumption. The small size of the arc-shaped tooth segment 620 reduces the area for high-precision processing, significantly reducing the processing difficulty and lowering the requirements for processing equipment and processes, thereby significantly reducing processing costs.

[0081] In some embodiments, such as Figure 7 As shown, the vertigo treatment device also includes an arc-shaped transition section 700. An arc-shaped transition section 700 is provided between adjacent arc-shaped toothed sections 620. The outer circumferential surface of the arc-shaped transition section 700 does not have a toothed structure. The arc-shaped transition section 700 is used to fill the gaps between the arc-shaped toothed sections 620. The arc-shaped transition section 700 and the arc-shaped toothed sections 620 are spliced ​​together to form a circle to ensure the integrity of the circumference. The arc-shaped transition section 700 can be detachably mounted on the rotating component 200 like the arc-shaped toothed sections 620, or it can be integrally formed with the rotating component 200.

[0082] The arc-shaped transition section 700 and the arc-shaped toothed section 620 are joined together to form a complete circle. This complete circle is concentrically arranged with the rotating component 200. The toothed transmission component 500 is wound around the drive gear 400, the arc-shaped transition section 700, and the arc-shaped toothed section 620. When the drive gear 400 rotates, it drives the arc-shaped toothed section 620 and the rotating component 200 to rotate synchronously through the toothed transmission component 500. The outer circumference of the arc-shaped transition section 700 has no teeth, resulting in low processing requirements, low cost, and low installation requirements.

[0083] Since the arc-shaped tooth segments are locally spliced, leaving gaps directly between the tooth segments may result in insufficient circumferential strength of the rotor. However, by setting an arc-shaped transition segment that matches the shape of the arc-shaped tooth segments but does not have teeth, the continuity of the rotor's circular profile and the balance of forces can be maintained.

[0084] In this embodiment, the number of arc-shaped tooth segments 620 can be one or more, and the number of arc-shaped transition segments 700 can also be one or more; when the number of arc-shaped tooth segments 620 is multiple, the multiple arc-shaped tooth segments 620 are distributed at intervals, and an arc-shaped transition segment 700 is provided between two adjacent arc-shaped tooth segments 620.

[0085] In the first implementation, such as Figure 7 As shown, there is only one arc-shaped tooth segment 620, and one or more arc-shaped transition segments 700. One arc-shaped tooth segment 620 and one or more arc-shaped transition segments 700 are joined to form a circle concentric with the rotating component 200. In this implementation, the arc-shaped tooth segment 620 needs to be relatively long to ensure that no matter what angle the rotating component 200 rotates at, its arc-shaped tooth segment 620 is always engaged with the toothed transmission component 500.

[0086] In the second implementation, such as Figure 8 As shown, there are two arc-shaped tooth segments 620 and two or more arc-shaped transition segments 700. The two arc-shaped tooth segments 620 are spaced apart by the arc-shaped transition segments 700, but it must be ensured that no matter what angle the rotating component 200 rotates at, one arc-shaped tooth segment 620 is always engaged with the toothed transmission component 500. In this implementation, the length of the arc-shaped tooth segments 620 is not limited, and the two arc-shaped tooth segments 620 can be arranged spaced apart by the arc-shaped transition segments 700.

[0087] In the third implementation, such as Figure 9 As shown, there are three or more arc-shaped tooth segments 620 and three or more arc-shaped transition segments 700; regardless of the rotation angle of the rotating component 200, there are always multiple arc-shaped tooth segments 620 meshing with the toothed transmission component 500. In this implementation, the arc-shaped tooth segments 620 are evenly arranged with small intervals, resulting in more stable operation.

[0088] In the fourth implementation, there are multiple arc-shaped tooth segments 620, which are directly spliced ​​together to form a complete circular gear, resulting in smooth operation.

[0089] In some embodiments, the side of the rotating member 200 protrudes with positioning steps for positioning the arc-shaped tooth segment 620 and the arc-shaped transition segment 700, and a portion of the outer surface of the arc-shaped tooth segment 620 and the arc-shaped transition segment 700 abuts against the positioning steps. In one example, the side of the rotating member 200 may be provided with a full circle of positioning steps, which radially positions the arc-shaped tooth segment 620 and the arc-shaped transition segment 700, and then the arc-shaped tooth segment 620 and the arc-shaped transition segment 700 are fixedly installed on the rotating member 200 with bolts. In another example, the side of the rotating member 200 may also be provided with multiple positioning steps at intervals, with the multiple positioning steps on the same ring, which radially positions the arc-shaped tooth segment 620 and the arc-shaped transition segment 700.

[0090] In some embodiments, such as Figure 1 As shown, the vertigo diagnosis and treatment device also includes multiple sets of guide wheels 800. The multiple sets of guide wheels 800 are installed on the frame 100 and are evenly distributed around the rotating member 200 along the circumference of the rotating member 200. The multiple sets of guide wheels 800 contact the rotating member 200 respectively, so as to limit the rotation direction of the rotating member 200 to only rotate around its center.

[0091] Multiple guide wheels 800 are provided with grooves or protrusions. The guide wheels 800 cooperate with the arc-shaped guide rail 610 on the rotating component 200 to limit the movement direction of the rotating component 200. Preferably, the multiple guide wheels 800 are V-shaped wheels or arc-shaped wheels. The multiple guide wheels 800 are made of rubber-like material, while the arc-shaped guide rail 610 is made of rigid material, resulting in low noise during operation of the rotating component 200. Furthermore, the guide wheels 800 are connected to an operating mechanism for manually rotating the rotating component 200 to release the patient in case of power failure or equipment malfunction.

[0092] In some embodiments, such as Figure 1 , Figures 7 to 9As shown, the frame 100 is also provided with a tensioning wheel 900, which contacts the toothed transmission component 500 and is used to increase the wrap angle between the toothed transmission component 500 and the drive gear 400, so that the toothed transmission component 500 can better mesh with the arc-shaped tooth segment 620. At the same time, the tensioning wheel 900 can also be used to adjust the tension of the toothed transmission component 500.

[0093] In some embodiments, the outer circumferential surface of the rotating member 200 is provided with a mounting groove, and the arc-shaped tooth segment 620 is fixedly installed in the mounting groove, with the arc-shaped tooth segment 620 and the outer circumferential surface of the rotating member 200 forming a circle. The toothed transmission member 500 is wound around the rotating member 200, the arc-shaped tooth segment 620 and the drive gear 400. When the drive gear 400 rotates, the toothed transmission member 500 drives the arc-shaped tooth segment 620 and the rotating member 200 to rotate together.

[0094] In some embodiments, a rotary electrical connection device is further included, which is installed between the rotating member 200 and the frame 100, for continuously supplying power or transmitting electrical signals during rotation, and for solving the problem of cable entanglement during rotation. Specifically, the stationary part of the rotary electrical connection device is connected to the frame 100, and its rotating part is coaxially connected to the rotating member 200. Preferably, the stationary part of the rotary electrical connection device is connected to the frame 100 through a mounting structure containing an elastic element. The following description uses a conductive slip ring as an example of the rotary electrical connection device. Figure 10 As shown, the conductive slip ring includes a conductive slip ring rotor 253 and a conductive slip ring stator 254. The conductive slip ring rotor 253 (rotating part) is coaxially connected to the rotating component 200, and the conductive slip ring stator 254 (stationary part) is connected to the frame 100. Specifically, the conductive slip ring rotor 253 is fixedly connected to the rotating component 200 through a first connecting arm 251 and a second connecting arm 252. The mounting structure connecting the conductive slip ring stator 254 (stationary part) to the frame 100 is equipped with elastic elements, such as bellows 151, hoses, springs, or rubber pads. When the rotating component 200 has a slight concentricity deviation due to splicing, the elastic element can absorb the deviation, preventing uneven force or oscillation of the slip ring, thereby extending the slip ring's lifespan. Therefore, the elastic mounting structure significantly reduces the requirements for the coaxiality of the slip ring assembly and improves the overall reliability of the equipment.

It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the protection scope of this application.
