Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, in particular to a dizziness diagnosis and treatment equipment. BACKGROUND

[0002] The vestibule is the main organ of human balance, among which the semicircular canal, as the key structure for sensing the position change of the head in the vestibule, plays an irreplaceable role. The semicircular canal is divided into horizontal semicircular canal, superior semicircular canal and posterior semicircular canal, which are perpendicular to each other and sense the dynamic changes of the head position in different planes. When the posture of the human body changes, the stimulation intensity received by each semicircular canal will be different due to the difference in the change direction. Once the stimulation received by the bilateral semicircular canals is unbalanced, the nystagmus phenomenon will be triggered, and the direction of the nystagmus is towards the side receiving stronger stimulation. Based on this scientific principle, by implementing acceleration or deceleration rotation operation on different semicircular canal planes, the corresponding semicircular canal can be stimulated in a targeted manner. In this process, the doctor can comprehensively and accurately grasp the balance state of the bilateral vestibular function and the functional status of each semicircular canal by means of careful examination of the nystagmus. Especially in the case of positional vertigo caused by the dislocation of ear stones, using a specific body position to reset the dislocated ear stones can effectively cure the vertigo symptoms of most patients in the clinic.

[0003] As a core medical device for fixing the human body, conducting semicircular canal function detection and further evaluating the vestibular function, the dizziness diagnosis and treatment equipment plays a crucial role in the diagnosis and treatment of dizziness. Most of the existing dizziness diagnosis and treatment equipment adopts a transmission mode of gear meshing with a large gear ring, and the design purpose is to accurately control the rotation of the rotating chair. However, this large gear ring rotating chair transmission structure has many drawbacks that are difficult to overcome. As a super large size precision part, the large gear ring has very high requirements for machining precision, deformation control and assembly precision, otherwise it will not only produce a lot of noise, but also affect the meshing precision of the gear and the large gear ring. At the same time, the large gear ring rotating chair is limited by the machining deformation and tooth shape strength of the large gear ring, so the large gear ring must be made of steel, which makes the large gear ring heavy and has large moment of inertia, not only requiring a large power motor to drive, but also having high energy consumption. Moreover, due to the large weight and size of the large gear ring, transportation and installation are difficult. SUMMARY

[0004] The purpose of the present application is to provide a dizziness diagnosis and treatment equipment that not only meets the requirement of the position staying accuracy of the rotating part, but also reduces the processing and installation difficulty. More preferably, the dizziness diagnosis and treatment equipment of the present application can reduce the weight and moment of inertia of the rotating structure, and further reduce the power of the driving motor.

[0047] In addition, in the description of the present application, ordinal numbers, such as "first", "second", etc., are only used to distinguish the description of the associated objects, and cannot be understood as indicating or implying the relative importance or order between the associated objects.

[0048] One embodiment of the application provides a dizziness diagnosis and treatment device, as shown in Figure 1 The device includes a rack 100, a rotating part 200, a bearing mechanism, a first driving mechanism and a second driving mechanism.

[0049] The rack 100 is a basic support structure of the device, which is in the form of a frame as a whole, and is used for mounting the bearing mechanism and the driving mechanism. The rack 100 can adopt a metal profile or a welded structure, has good stability and bearing capacity, and ensures strength and stability. The bottom of the rack 100 can be provided with a plurality of supporting feet for balancing the entire swivel chair and preventing shaking. The bottom of the supporting feet can also be provided with rollers to facilitate the movement of the entire swivel chair.

[0050] The rotating member 200 is in the form of a ring structure or a disc structure, and is rotatably arranged on the rack 100 and can rotate around a horizontal axis 20 passing through the center of the rotating member 200 under the driving of the second driving mechanism. Specifically, the horizontal axis 20 is a central axis passing through the center of the rotating member 200 and perpendicular to the ring / disc surface, or a transverse axis passing through the center of the rotating member 200 (the rotating mode is overturning). According to the rotating mode of the rotating member 200, the horizontal axis 20 can be different. In this embodiment, the cross section of the rotating member 200 can be provided in the form of a hollow or a honeycomb. When the cross section of the rotating member 200 is hollow, reinforcing ribs can be arranged in the rotating member 200 to improve the rigidity and strength of the rotating member 200. Not only does this make the overall rigidity and strength of the rotating member 200 meet the requirements, but also makes the weight of the rotating member 200 relatively low, thereby reducing the moment of inertia of the rotating member 200 and the required driving motor power, and reducing energy consumption. The rotating member 200 can be in the form of an integral structure. Alternatively, the rotating member 200 can be in the form of a combined structure formed by splicing a plurality of arc segments, and the arc segments are fixed to each other to form a whole circle by screwing, welding, inserting or other connecting methods.

[0051] The bearing mechanism is mounted on the rotating member 200 and is used for bearing the patient. The bearing mechanism 300 includes a bearing support 310 and a seat 320, the seat 320 is mounted on the bearing support 310, and the bearing support 310 is connected with the rotating member 200. In order to improve the rotating stability of the seat 320, the seat 320 can be connected with the rack 100 through a rotating shaft and a bearing, etc., to realize stable rotation of the seat 320, wherein the rotating shaft of the seat 320 coincides with the center of the rotating member 200. Further, the dizziness diagnosis and treatment device further includes a safety belt system and a head fixing device, and the patient is reliably fixed on the seat 320 through the safety belt system and the head fixing device. In another embodiment, a horizontal adjustment mechanism is arranged between the seat 320 and the bearing support 310. The horizontal adjustment mechanism is used for moving the seat 320 relative to the bearing support 310 in the horizontal direction, so as to adjust the distance between the seat 320 and the vertical axis 10.

[0052] For example, when eccentric test is needed, the seat 320 can be adjusted to a position with a certain offset from the vertical axis 10 by the horizontal adjustment mechanism, and fixed after adjustment, so that when the seat 320 rotates around the vertical axis 10 later, the patient will be subjected to a corresponding centrifugal force due to the offset between the center of the seat 320 and the rotation axis (vertical axis 10) during rotation. At this time, the patient's left and right ears will bear different sizes of centrifugal force due to different positions, thereby forming an asymmetric vestibular stimulation. In this way, the balance response and vestibular system function of the subject in an asymmetric acceleration environment can be simulated and detected, and it is especially suitable for eccentric rotation test in the diagnosis and treatment of dizziness.

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

[0054] Slide rail and screw rod transmission mechanism: the seat 320 is driven to slide horizontally along the slide rail by the screw rod, and is fixed by the self-locking of the screw rod;

[0055] Rack and pinion transmission mechanism: the gear and the rack are engaged to drive the seat 320 to move in the horizontal direction, and can be fixed by the engagement relationship after stopping driving;

[0056] Electric push rod mechanism: the horizontal position of the seat 320 is adjusted by the extension and retraction of the push rod, and the push rod is locked after stopping action;

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

[0058] Through the above different structural forms, the adjustment and fixation of the position of the seat 320 can be realized, 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 driving mechanism is installed on the rack 100 or the bearing mechanism, and is used to drive the bearing mechanism to rotate horizontally around the vertical axis 10, so as to realize the rotation of the seat 320, thereby quickly positioning or turning the patient in different body 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 driving mechanism is used to drive the rotating member 200 to rotate around the horizontal axis 20, so that the patient rotates synchronously. For example, the second driving mechanism includes Figure 1 the driving gear 400, which drives the rotating member 200 to rotate through the tooth-shaped transmission member 500.

[0061] In use of the dizziness diagnosis and treatment device, the patient sits on the seat 320 and fastens the safety belt on the seat 320, and then the second driving mechanism is started to drive the rotating member 200 to rotate synchronously. The rotation of the rotating member 200 is transmitted to the patient through the seat 320, so as to realize detection or treatment of the patient. In the process of rotating the seat 320 driven by the rotating member 200, the first driving mechanism is also used to drive the seat 320 to rotate around the vertical axis 10, so as to realize three-dimensional rotation of the seat 320.

[0062] In the embodiment, the first driving mechanism and the second driving mechanism are cooperatively controlled, so that the patient can perform multi-degree-of-freedom rotation operation in three-dimensional space, different vestibular function tests are met, and the purpose of dizziness diagnosis and treatment is achieved. By controlling the rotation speed and angle of the motor of the first driving mechanism and the second driving mechanism, the rotation speed and position of the seat 320 can be adjusted to meet the treatment needs of different patients.

[0063] In the embodiment, the rotating member 200 adopts a segmented splicing structure. According to different implementation manners, the rotating member 200 itself can be spliced by a plurality of arc segments, or a plurality of arc splicing members can be installed on the rotating member 200. Compared with the large gear ring integrated structure in the prior art, the segmented splicing structure or the structure of installing arc splicing members on the rotating member not only reduces the area of high-precision machining, significantly reduces the machining difficulty, reduces the requirements on machining equipment and machining process, thereby significantly reduces the machining cost, but also reduces the weight and inertia of the rotating member, and the required power of the driving motor is also reduced.

[0064] In one embodiment, the rotating member 200 itself is spliced by arc segments: the rotating member 200 is formed by splicing a plurality of arc segments, and the arc segments can be annular arc segments (annular splicing parts) or fan-shaped segments (disc splicing parts); adjacent arc segments are fixedly connected through structures such as bolts and positioning pins, and form a complete ring or disc after splicing. As shown in Figure 2 and Figure 3 As shown in the drawings, the rotating member 200 of the ring is spliced by two annular arc segments 201 or a plurality of annular arc segments 201, and adjacent annular arc segments 201 are fixedly connected through fixing devices such as positioning pins 202 to form a stable rotor. Preferably, the arc-shaped edge of the arc segment has a tooth-shaped structure, and the adjacent arc segments are continuously distributed in the circumferential direction after splicing, and form a rotating member 200 similar to a gear ring as a whole. The rotating member 200 is engaged and driven with the driving gear 400 or other tooth-shaped transmission members, so as to drive the rotating member 200 to rotate synchronously. The arc-shaped edge of the arc segment can be the outer arc edge, the inner arc edge of the arc segment, or the lateral circumferential surface of the arc segment. When the arc segment is not provided with a tooth-shaped structure, the rotating member 200 can be driven to rotate through a friction mode or a double-guide rail driving mode.

[0065] In another embodiment, a plurality of arc-shaped segments are installed on the rotating member 200, and the arc-shaped segments are arc-shaped guide rails 610. The arc-shaped guide rails 610 can be installed along the circumferential direction of the rotating member 200. Specifically, the installation position is, for example, the outer periphery, the inner periphery, or the end face of the rotating member 200.

[0066] For example, when installed on the outer periphery, as shown in FIG. 2A, the arc-shaped guide rails 610 are installed on the outer periphery of the rotating member 200, and the arc-shaped guide rails 610 are provided with protrusions or grooves arranged in the circumferential direction. Preferably, a plurality of guide wheels 800 are arranged on the rack 100 along the circumferential direction of the rotating member, and the guide wheels 800 are provided with grooves or protrusions matched with the shape of the arc-shaped guide rails 610 to cooperate with the operation of the arc-shaped guide rails 610. Figure 4 For example, when installed on the inner periphery, as shown in FIG. 2B, a plurality of arc-shaped guide rails 610 are installed on the inner periphery of the rotating member 200, and the arc-shaped guide rails 610 are provided with protrusions or grooves arranged in the circumferential direction. Preferably, a plurality of guide wheels 800 are arranged on the rack 100 along the circumferential direction of the rotating member, and the guide wheels 800 are provided with grooves or protrusions matched with the shape of the arc-shaped guide rails 610 to cooperate with the operation of the arc-shaped guide rails 610.

[0067] Figure 5 For example, when installed on the inner periphery, as shown in FIG. 2B, a plurality of arc-shaped guide rails 610 are installed on the inner periphery of the rotating member 200, and the arc-shaped guide rails 610 are provided with protrusions or grooves arranged in the circumferential direction. Preferably, a plurality of guide wheels 800 are arranged on the rack 100 along the circumferential direction of the rotating member, and the guide wheels 800 are provided with grooves or protrusions matched with the shape of the arc-shaped guide rails 610 to cooperate with the operation of the arc-shaped guide rails 610.

[0068] The arc-shaped guide rails 610 (such as the outer arc-shaped guide rails or the inner arc-shaped guide rails) described above are arc-shaped members, and the track surface is a circular arc track. A plurality of arc-shaped guide rails 610 are continuously spliced in the circumferential direction to form a ring-shaped guide rail. The splicing can be fixed by screws, pins, or positioning grooves, etc., to ensure that the guide rail track is continuous and smooth.

[0069] The ring-shaped guide rail formed by splicing cooperates with the guide wheel 800, so that when the rotating member 200 rotates, the radial centrifugal force generated in the rotating process of the bearing mechanism is shared, the relative radial or axial deviation of the bearing mechanism relative to the track is prevented, and the guiding, limiting, and stabilizing effects are achieved.

[0070] Specifically, if the arc-shaped guide rails 610 are installed on the inner periphery or the outer periphery of the rotating member 200, the installation position of the second driving mechanism should be staggered with the guide rail formed by splicing the arc-shaped guide rails 610. The following are several example driving schemes:

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

[0072] ​When the inner periphery of the rotating member 200 is provided with a ring-shaped guide rail spliced by arc-shaped guide rails 610, the guide rail is used for guiding and limiting the rotation of the bearing mechanism. In order to realize the rotation of the rotating member 200 around the central axis passing through the center of the rotating member 200 and perpendicular to the ring / disk surface, a slewing bearing is arranged at the center of the rotating member 200, one side of the slewing bearing is fixed to the rack 100, and the other side is connected to the rotating member 200. The second driving mechanism includes a driving motor and a speed reducer, the output end of which is engaged with the driving gear ring of the slewing bearing, or connected to the rotating ring of the slewing bearing through a shaft coupling, so as to drive the rotating member 200 to rotate around the central axis. The ring-shaped guide rail and the second driving mechanism are arranged in layers in the axial direction and do not interfere with each other.

[0073] In other embodiments, the end surface of the rotating member 200 is provided with a driving gear ring (or a synchronous belt gear ring / friction ring), and the second driving mechanism is fixed to the rack 100, and the pinion (or pulley / friction wheel) at the output end of the second driving mechanism is engaged with / contacts the end surface driving ring to input a rotation torque around the central axis to the rotating member 200. The ring-shaped guide rail at the inner periphery is located at an axial position different from the end surface driving gear ring, so as to realize the decoupling of the driving and guiding functions.

[0074] Further, the outer circle of the rotating member 200 is provided with a gear ring or a friction ring, and the second driving mechanism realizes the self-rotation driving of the rotating member 200 through the driving wheel engaged / pressed with the gear ring or the friction ring; in order to improve the stability, a plurality of driving / support wheels can be arranged in the circumferential direction and pre-tightened.

[0075] More preferably, the adjacent arc-shaped segments are detachably connected; and / or; the arc-shaped splicing members and the rotating member 200 are detachably connected, so as to facilitate subsequent installation and maintenance.

[0076] In another embodiment, as shown in Figure 6 , a plurality of arc-shaped splicing members are mounted on the rotating member 200, the arc-shaped splicing members are arc-shaped tooth segments 620, the arc-shaped tooth segments 620 are part of a circular ring, and the center of the arc-shaped tooth segment 620 coincides with the center of the rotating member 200 after the arc-shaped tooth segment 620 is mounted on the rotating member 200. The arc-shaped tooth segment 620 is a toothed arc-shaped member, which has a tooth structure for engagement, and the arc-shaped tooth segment 620 can be mounted on the inner periphery, the outer periphery or the lateral circumferential surface of the overall rotating member 200 to form a partial or complete gear ring. The length of the arc-shaped tooth segment 620 can be designed according to actual needs, but it is necessary to ensure that the arc-shaped tooth segment 620 always engages with the toothed transmission member 500 during rotation. As shown in Figure 6 , the inner periphery of the rotating member 200 is provided with arc-shaped tooth segments 620, and a plurality of arc-shaped tooth segments 620 mounted on the inner periphery of the rotating member 200 form an inner gear ring concentric with the rotating member 200. Figure 6In this embodiment, the rotating member 200 is a whole annular structure, which has better stability. Of course, the rotating member 200 can also be a spliced structure, such as the splicing structure formed by the arc-shaped segments in the foregoing solution, which is not limited herein.

[0077] The number of the arc-shaped tooth segments 620 is several (two or more), which can be continuously arranged along the circumferential direction of the rotating member 200 to form a large gear ring. The arc-shaped tooth segments 620 are fixed by bolts or plug-in structures, and a positioning pin, a positioning step or an abutting surface is arranged at the connecting position to ensure the positioning accuracy and the continuity of the tooth pitch.

[0078] Of course, the arc-shaped tooth segments 620 can also be arranged at intervals along the circumferential direction of the rotating member 200, such as two arc-shaped tooth segments 620 symmetrically arranged on the rotating member 200, or a plurality of arc-shaped tooth segments 620 arranged at intervals.

[0079] In this embodiment, the second driving mechanism includes a driving gear 400 mounted on the rack 100. A motor is also arranged on the rack 100. The driving gear 400 is driven by the motor. The driving gear 400 is directly engaged with the arc-shaped tooth segment 620. The tooth shape of the driving gear 400 matches the tooth shape of the tooth-shaped transmission member 500, which ensures that the driving gear 400 and the tooth-shaped transmission member 500 can be stably engaged, and ensures the stability and reliability in the transmission process. Alternatively, the driving gear 400 is indirectly driven with the arc-shaped tooth segment 620 through the tooth-shaped transmission member 500 such as a tooth-shaped belt or chain. When the driving gear 400 rotates, the continuous or discontinuous gear ring formed by the arc-shaped tooth segments 620 is driven to rotate, thereby driving the rotating member 200 to rotate as a whole around the horizontal axis 20. Through the arc-shaped tooth segments 620 mounted on the rotating member 200, a large-diameter gear ring can be formed, which avoids the difficulty of overall machining, reduces the manufacturing cost, and ensures the engagement accuracy. In addition, the arc-shaped tooth segment 620 is made of aluminum alloy material, which can greatly reduce the weight of the rotor (rotating member) and reduce the power of the motor.

[0080] In this embodiment, the rotating speed ratio of the driving gear 400 and the arc-shaped tooth segment 620 is constant. The position and speed of the rotating member 200 can be accurately controlled by adjusting the rotating speed and angle of the driving gear 400, which meets the functional requirements of the position and stay accuracy of the dizziness diagnosis and treatment equipment, and improves the treatment effect. The rotating member 200 and the arc-shaped tooth segment 620 are designed separately, compared with the large gear ring structure in the prior art, the machining requirement and material requirement of the rotating member 200 can be reduced, the rotating member 200 can be made of more common and economical materials, which not only saves the production cost, but also reduces the weight and inertia of the rotating member 200, the required driving motor power is also reduced, and the energy consumption is reduced. The size of the arc-shaped tooth segment 620 is small, the high-precision machining area is reduced, the machining difficulty is significantly reduced, the requirements for machining equipment and machining process are reduced, and the machining cost is significantly reduced.

[0081] In some embodiments, asFigure 7 As shown in the figure, the dizziness diagnosis and treatment device further comprises an arc-shaped transition section 700, the arc-shaped transition section 700 is arranged between adjacent arc-shaped tooth sections 620, the outer circumferential surface of the arc-shaped transition section 700 is not provided with a tooth structure, the arc-shaped transition section 700 is used for filling the gap between the arc-shaped tooth sections 620 arranged at intervals, and the arc-shaped transition section 700 is spliced with the arc-shaped tooth sections 620 to form a circle, so as to ensure the integrity of the circle. The arc-shaped transition section 700 can be detachably mounted on the rotating member 200 like the arc-shaped tooth sections 620, or can be integrally formed with the rotating member 200.

[0082] The arc-shaped transition section 700 and the arc-shaped tooth sections 620 are spliced with each other to form a complete circle, the complete circle is arranged concentrically with the rotating member 200, and the tooth-shaped transmission member 500 is arranged around the driving gear 400, the arc-shaped transition section 700 and the arc-shaped tooth sections 620. When the driving gear 400 rotates, the arc-shaped tooth sections 620 and the rotating member 200 are driven to rotate synchronously by the tooth-shaped transmission member 500. The outer circumferential surface of the arc-shaped transition section 700 is toothless, and the machining requirement, cost and installation requirement are low.

[0083] Since the arc-shaped tooth sections are locally spliced, if the gap is directly left between the tooth sections, the circumferential strength of the rotor may be insufficient, and the arc-shaped transition section matching the shape of the arc-shaped tooth section but without teeth can maintain the continuity and force balance of the circular profile of the rotor.

[0084] In the embodiment, the number of the arc-shaped tooth sections 620 can be one or more, and the number of the arc-shaped transition sections 700 can also be one or more. When the number of the arc-shaped tooth sections 620 is multiple, the multiple arc-shaped tooth sections 620 are arranged at intervals, and one arc-shaped transition section 700 is arranged between adjacent two arc-shaped tooth sections 620.

[0085] In the first implementation mode, as shown in the figure, Figure 7 the number of the arc-shaped tooth sections 620 is one, and the number of the arc-shaped transition sections 700 is one or more. One arc-shaped tooth section 620 and one or more arc-shaped transition sections 700 are spliced to form a circle concentric with the rotating member 200. In the implementation mode, the arc-shaped tooth section 620 needs to be arranged relatively long, so as to ensure that the arc-shaped tooth section 620 is always meshed with the tooth-shaped transmission member 500 regardless of the angle at which the rotating member 200 rotates.

[0086] In the second implementation mode, as shown in the figure, Figure 8 the number of the arc-shaped tooth sections 620 is two, and the number of the arc-shaped transition sections 700 is two or more. The two arc-shaped tooth sections 620 are arranged at intervals through the arc-shaped transition sections 700, but it is ensured that one of the arc-shaped tooth sections 620 is always meshed with the tooth-shaped transmission member 500 regardless of the angle at which the rotating member 200 rotates. In the implementation mode, the length of the arc-shaped tooth section 620 is not limited, and the two arc-shaped tooth sections 620 can be arranged at intervals through the arc-shaped transition sections 700.

[0087] In the third implementation, as shown in Figure 9 , the number of arc-shaped tooth segments 620 is three or more, and the number of arc-shaped transition segments 700 is also three or more; no matter at what angle the rotating member 200 rotates, there are always multiple arc-shaped tooth segments 620 engaged with the tooth-shaped transmission member 500. In this implementation, the arc-shaped tooth segments 620 are uniformly arranged and have a small interval, and the operation is more stable.

[0088] In the fourth implementation, the number of arc-shaped tooth segments 620 is multiple, and the multiple arc-shaped tooth segments 620 are directly spliced into a complete circular gear, and the operation is stable.

[0089] In some embodiments, the side of the rotating member 200 protrudes and is provided with a positioning step for positioning the arc-shaped tooth segments 620 and the arc-shaped transition segments 700, and a part of the outer surface of the arc-shaped tooth segments 620 and the arc-shaped transition segments 700 abuts against the positioning step. In an example, the side of the rotating member 200 can be provided with a whole circle of positioning steps, and the arc-shaped tooth segments 620 and the arc-shaped transition segments 700 are radially positioned by the whole circle of positioning steps, and then the arc-shaped tooth segments 620 and the arc-shaped transition segments 700 are fixedly installed on the rotating member 200 by bolts. In another example, the side of the rotating member 200 can also be provided with multiple positioning steps at intervals, and the multiple positioning steps are on the same circular ring, and the arc-shaped tooth segments 620 and the arc-shaped transition segments 700 are radially positioned by the multiple positioning steps.

[0090] In some embodiments, as shown in Figure 1 , the dizziness diagnosis and treatment device further comprises multiple sets of guide wheels 800, which are installed on the rack 100 and arranged around the rotating member 200 in the circumferential direction of the rotating member 200; the multiple sets of guide wheels 800 respectively contact the rotating member 200 to limit the rotation direction of the rotating member 200 to only rotate around the center thereof.

[0091] The multiple sets of guide wheels 800 are provided with grooves or protrusions, and the guide wheels 800 cooperate with the arc-shaped guide rails 610 on the rotating member 200 to limit the movement direction of the rotating member 200. Preferably, the multiple sets of guide wheels 800 are respectively V-shaped wheels or circular arc wheels. The multiple sets of guide wheels 800 are respectively made of rubber-like materials, and the arc-shaped guide rails 610 are made of hard materials, so that the rotating member 200 has small noise during operation. Further, the guide wheels 800 are connected with an operating mechanism for manually rotating the rotating member 200 when power is off or the device fails, so as to release the patient.

[0092] In some embodiments, as shown in Figure 1 , Figures 7 to 9As shown, the rack 100 is also provided with a tensioning wheel 900, which is in contact with the toothed transmission member 500, for increasing the wrap angle of the toothed transmission member 500 and the drive gear 400, so that the toothed transmission member 500 is better engaged with the arc-shaped tooth segment 620. Meanwhile, the tensioning wheel 900 can also be used to adjust the tightness of the toothed transmission member 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, and the arc-shaped tooth segment 620 and the outer circumferential surface of the rotating member 200 form a circle. The toothed transmission member 500 is arranged around the rotating member 200, the arc-shaped tooth segment 620 and the drive gear 400. When the drive gear 400 rotates, the arc-shaped tooth segment 620 and the rotating member 200 are driven to rotate together through the toothed transmission member 500.

[0094] In some embodiments, a rotary electrical connection device is also included, which is installed between the rotating member 200 and the rack 100, for continuously supplying power or transmitting electrical signals during rotation and solving the problem of cable winding during rotation. Specifically, the stationary part of the rotary electrical connection device is connected with the rack 100, and the rotating part is coaxially connected with the rotating member 200. Preferably, the stationary part of the rotary electrical connection device is connected with the rack 100 through a mounting structure containing elastic elements. Hereinafter, the rotary electrical connection device is taken as an example of a conductive slip ring for illustration, as shown in Figure 10 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 with the rotating member 200, and the conductive slip ring stator 254 (stationary part) is connected with the rack 100. Specifically, the conductive slip ring rotor 253 is fixedly connected with the rotating member 200 through a first connecting arm 251 and a second connecting arm 252. The mounting structure of the conductive slip ring stator 254 (stationary part) connected with the rack 100 is provided with elastic elements, such as bellows 151, hoses, springs or rubber pads, etc. When the rotating member 200 has a slight concentricity deviation due to splicing, the elastic elements can absorb the deviation, avoiding uneven force or swinging of the slip ring, thereby prolonging the service life of the slip ring. Therefore, the elastic mounting structure significantly reduces the requirement for the coaxiality of the slip ring assembly, and improves the overall reliability of the equipment.
