TECHNICAL FIELD
[0001] The present application relates to a reset device for cupulolithiasis, belonging to the technical field of medical devices. BACKGROUND
[0002] Benign paroxysmal positional vertigo (BPPV), commonly known as "otolithiasis", is a peripheral vestibular disease induced by changes in head position relative to gravity, characterized by repeated episodes of transient vertigo and characteristic nystagmus, and is the most common vertigo disease. Cupulolithiasis is a relatively rare type of BPPV classification, because the otolith particles on the utricular macula fall off and adhere to the cupula of the ampullary ridge, causing a change in the density of the cupula relative to the endolymph, making it sensitive to gravity, and thus causing corresponding symptoms and signs.

Detailed Implementation
[0019] like Figures 1 to 16As shown, a repositioning device for sacral calculi in this embodiment includes an arc-shaped connecting bridge 1. Both ends of the connecting bridge 1 are provided with vibration mechanisms 2. The two vibration mechanisms 2 are symmetrically arranged. The vibration mechanisms 2 generate vibration and act on the otolith particles attached to the sacral calculi, so that the otoliths move in the semicircular canals and assist in the repositioning of the otoliths. The connecting bridge 1 is provided with two reset model mechanisms 3, which correspond one-to-one with two vibration mechanisms 2. Each reset model mechanism 3 includes a model body 301, which is connected to the connecting bridge 1. Specifically, the model body 301 is fixedly provided with a bracket 302, and one end of the bracket 302 is ball-jointed to a connecting block 303. The connecting bridge 1 is provided with a mounting base 4, which is provided with a protruding strip 5. The connecting block 303 is provided with a first groove 304, which is a dovetail groove. The protruding strip 5 matches the first groove 304 and is inserted into the first groove 304. The model body 301 is provided with a plurality of model rods 305. Here, the number and shape of the model rods 305 are consistent with the number and shape of the semicircular canals of a single ear in the human body. A model ball 306 is slidably connected to the model rods 305. Here, the model ball 306 is used to simulate the otolith particles in the semicircular canals. The model sphere 306 includes a sphere 3061, which has a cavity inside. A through-passage is provided on the sphere 3061, which passes through the cavity inside the sphere 3061. The model rod 305 passes through the through-passage. Two locking members are provided on the sphere 3061, which are symmetrically arranged about the center of the sphere 3061. The locking component includes a push plate 3062 and an elastic locking strip 3063. The push plate 3062 is located outside the ball 3061, and the locking strip 3063 is located inside the ball 3061. Two push rods 3064 are fixedly mounted on the push plate 3062. The two push rods 3064 are arranged side by side and pass through the ball 3061. The two ends of the locking strip 3063 are fixedly connected to the two push rods 3064 respectively. In the two locking components, the push rod 3064 in one locking component is connected to the opposite push rod 3064 in the other locking component by a first spring 3065; A magnet block 3066 is fixedly provided at the inner end of the push rod 3064, and the locking strip 3063 is provided at the magnet block 3066. The magnetic poles of the magnet block 3066 in one locking member and the opposite magnet block 3066 in the other locking member are opposite to each other. The magnet block 3066 is provided with a storage hole 3067, which extends into the push rod 3064, and the end of the first spring 3065 is located in the storage hole 3067. Both ends of the through-channel are provided with a set of ball bearings 3068, and each set of ball bearings 3068 is provided with multiple ball bearings 3068. Multiple ball bearings 3068 in the same set are circumferentially rolled and embedded into the inner wall of the through-channel, and the ball bearings 3068 abut against the model rod 305. The sphere 3061 includes two hemispherical parts 30611, which together form the sphere 3061. The two hemispherical parts 30611 are fixed by locking screws 30612. The vibration mechanism 2 includes a vibration box 201. The end of the connecting bridge 1 is provided with a mounting frame 6. The vibration box 201 is fixedly connected to the mounting frame 6. Specifically, the vibration box 201 is installed on the mounting frame 6. The vibration box 201 is provided with multiple positioning holes 202. The multiple positioning holes 202 are distributed along the direction of the vibration box 201 passing through the mounting frame 6. The mounting frame 6 is threaded with a positioning screw 203. One end of the positioning screw 203 is inserted into one of the positioning holes 202. In the two vibration mechanisms 2, the side of the two vibration boxes 201 that are close to each other is the inner side; The vibration box 201 has an inner opening, and a vibration plate 204 is fitted to the opening of the vibration box 201. A vibrating element is installed inside the vibration box 201, and the vibration plate 204 is vibrated by the vibrating element. The vibrating element includes a fixed disk 205 fixedly disposed on the outside of the vibrating plate 204. The axis of the fixed disk 205 is parallel to the arrangement direction of the two vibrating mechanisms 2. The outer side of the fixed disk 205 is provided with a plurality of second grooves 206, which are evenly distributed circumferentially around the axis of the fixed disk 205. A rotating disk 207 is disposed on the side of the fixed disk 205 away from the vibrating plate 204. A plurality of protrusions 208 are disposed on the side of the rotating disk 207 close to the fixed disk 205. The plurality of protrusions 208 correspond one-to-one with the plurality of second grooves 206. The protrusions 208 are inserted into the second grooves 206. The rotating disk 207 is driven by a motor 209. The protrusions 208 are hemispherical, and the second grooves 206 are arc-shaped. The depth to which the protrusions 208 are inserted into the second grooves 206 is less than the radius of the hemispherical protrusions 208. Two guide rods 210 are fixedly installed on the outer side of the vibrating plate 204. The two guide rods 210 are located on both sides of the rotating disk 207. The guide rods 210 are parallel to the rotating disk 207. A support block 211 is passed through the guide rod 210. The support block 211 is fixedly installed on the inner wall of the vibration box 201. The support block 211 is connected to the vibrating plate 204 by a second spring 212. The second spring 212 is sleeved on the guide rod 210. When using the repositioning device, the connecting bridge 1 is worn on the patient's head, and the two vibrating plates 204 are attached to the patient's mastoid process. Because the bracket 302 and the connecting block 303 are ball joints, it is easy to adjust the angle of the model body 301. During the repositioning of the otoliths, the patient's head is rotated to facilitate the movement of the otoliths along the expected trajectory in the semicircular canals. The specific operation is as follows: The motor 209 drives the rotating disk 207 to rotate, thereby causing the protrusion 208 to rotate intermittently into the second groove 206. When the protrusion 208 rotates out of the second groove 206, it can push the vibrating plate 204 to move inward and drive the guide rod 210 to move synchronously on the support block 211. At the same time, the second spring 212 deforms. When the protrusion 208 rotates to the position directly opposite the second groove 206, the elastic action of the second spring 212 causes the fixed disk 205 and the vibrating disk to move in opposite directions, so that the protrusion 208 is inserted into the second groove 206. This cycle is repeated, thus realizing the inner and outer circulation of the vibrating plate 204. That is, the vibrating plate 204 vibrates. When the protrusion 208 is inserted into the second groove 206, it can also vibrate, which further enhances the vibration effect. The vibration of the vibrating plate 204 is transmitted to the otolith particles that are attached to the ridge of the patient. Through vibration, the otolith particles are dislodged into the semicircular canals, which helps the otoliths to reposition. At this time, the repositioning model mechanism 3 is in the open state, that is, there is a gap between the two locking bars 3063 and the model rod 305. When the patient's head is turned, the model ball 306 moves on the model rod 305. The movement trajectory of the otolith in the semicircular canal is simulated by observing the movement trajectory of the model ball 306 on the model rod 305. Of course, when it is determined that the otolith in a certain semicircular canal needs to be repositioned, the model ball 306 on the corresponding model rod 305 of other semicircular canals can be locked. The specific positioning method is as follows. Pushing the push plate 3062 causes the guide rod 210 to move the locking strip 3063, so that the two locking strips 3063 move closer and fit against the model rod 305. At the same time, the two magnets 3066 attract each other and the first spring 3065 deforms. Here, through calculation, the elastic force generated by the first spring 3065 is less than the attraction force of the two magnets 3066. In this way, the model rod 305 is clamped by the two locking strips 3063, and the positioning between the model ball 306 and the model rod 305 is achieved. This avoids the interference caused by multiple model balls 306 moving at the same time during otolith repositioning, thus facilitating the observation of the model ball 306. In addition, when the model ball 306 is unlocked from the model rod 305, the push plate 3062 is pulled to move in the opposite direction, causing the locking bar 3063 to separate from the model rod 305 and the first spring 3065 to return to its original state. In this way, the model ball 306 can move normally on the model rod 305. Here, through the ball bearing 3068, the sliding friction between the ball 3061 and the model rod 305 can be converted into rolling friction, which reduces the frictional force and improves the smoothness of the ball 3061 moving on the model rod 305. It should be noted that when the positioning screw 203 is loosened, the vibration box 201 can be moved on the mounting frame 6, that is, the distance between the two vibration plates 204 can be adjusted to accommodate different head sizes. After the vibration box 201 is adjusted, tighten the positioning screw 203 so that the positioning screw 203 is inserted into the positioning hole 202. In summary, during otolith repositioning, vibration causes otolith particles adhering to the cervix to detach into the semicircular canals. This assists in otolith repositioning while simultaneously allowing observation of the movement of the model ball 306 on the model rod 305 to simulate the flow of otoliths within the semicircular canals. This accurately determines the position of the semicircular canals and otoliths in different body positions, facilitating rapid and precise otolith repositioning and improving the success rate and efficiency of cervix stone treatment. Furthermore, the model ball 306 can be selectively locked to the model rod 305 to prevent multiple model balls 306 from moving simultaneously during otolith repositioning and interfering with the model ball 306 to be observed, thus facilitating observation of the model ball 306. Additionally, when the vibration mechanism 2 vibrates, the reciprocating movement of the vibration plate 204 and the cyclic insertion of the protrusion 208 into the second groove 206 enhance the vibration effect, further assisting in otolith repositioning and improving the success rate and efficiency of treatment.
