Otolithiasis treatment device with calibration function

Abstract

The invention discloses an otolithiasis treatment instrument with a calibration function, comprising a semicircular canal model and a calibration device, wherein the calibration device comprises two parallel cylinders on the left and right sides, wherein two transparent reference plates are radially arranged in the front and rear directions of each cylinder, wherein calibration marks are marked on the reference plates, and the positions and directions of the front and rear calibration marks correspond to each other; wherein a left and right level gauge for calibrating the left and right levels is arranged behind the reference plates in the horizontal calibration cylinder, and a front and rear level gauge for calibrating the front and rear levels is arranged behind the reference plates in the front and rear calibration cylinder. By calibrating the relative positions of the head and the device body, the positions of the two are synchronized, so that the semicircular canal model is consistent with the direction of the semicircular canals of the human body. After synchronization, the left and right level gauges and the front and rear level gauges can be used to adjust the head position to a horizontal level so that the otolith position is reset to zero. This facilitates doctors to intuitively know the position of the otoliths without relying on their own imagination to simulate.

Description

Technical Field

[0001] The present invention relates to an otolithiasis treatment instrument, in particular to an otolithiasis treatment instrument with a calibration function Background Art

[0002] Otolithiasis, also known as benign paroxysmal positional vertigo, refers to brief paroxysmal attacks of vertigo and nystagmus that occur when the head moves rapidly to a specific position.

[0003] The vestibule is an organ responsible for the sense of balance, including three semicircular canals19 that play an important role in maintaining the body's balance. Figure 6 As shown, the semicircular canals 19 are connected to the cochlea 21. The three semicircular canals, namely the superior semicircular canal, the posterior semicircular canal and the lateral semicircular canal, have a structure that intersects each other at right angles. The vestibule also includes an otolith organ, which has the following structure: there are many short hairs growing luxuriantly, and there are tiny otoliths 20 at the front end of the short hairs. The shaking of the otoliths 20 is used to sense gravity and linear acceleration. When the head is moved, the lymph in the three semicircular canals also flows, and the hair cells produce nerve stimulation and transmit signals to the brain. The flow of lymph in a semicircular canal corresponding to the direction of movement of the head is stronger than the flow in the other two semicircular canals, so the brain is aware of the rotation of the head. In this way, using the functions of the vestibule and the three semicircular canals, the brain can be aware of the rotation of the head and the linear motion and acceleration of the body, so that the action of maintaining body balance can be performed.

[0004] Due to various reasons, the otolith 20 may be out of its original position and float inside the semicircular canal 19. The stimulation of the otolith 20 by the otolith 20 to the semicircular canal 19 is the cause of vertigo. Therefore, as long as the otolith that has entered the semicircular canal is taken out by any method, the vertigo can be completely eliminated.

[0005] The existing method for removing the otoliths 20 from the semicircular canals 19 is to move the patient's head back and forth and left and right to allow the otoliths 20 to move in the semicircular canals 19 and eventually be discharged from the openings of the semicircular canals.

[0006] This method requires the physician to have a good anatomical foundation and spatial imagination ability, requires certain experience and skills, and is difficult to operate.

[0007] Patent 201420752896.4 discloses a device for treating otolithiasis, which simulates the semicircular canals of the human body and uses the otoliths in the model to simulate the position of the actual otoliths in the semicircular canals, making them intuitively visible and reducing the difficulty of treatment.

[0008] However, in actual use, people generally rely on experience to wear the above-mentioned therapeutic devices, and it is difficult to synchronize the position angle of the model with the semicircular canals of the human body, which greatly reduces the effect of the model. Summary of the invention

[0009] In view of this, the present invention provides an otolithiasis treatment instrument with a calibration function, which can calibrate the positions of the semicircular canal model and the semicircular canals of the human body so that the directions of the two are consistent.

[0010] To solve the above technical problems, the technical solution of the present invention is to adopt an otolithiasis treatment instrument with a calibration function, including a semicircular canal model and a calibration device, wherein the calibration device includes two parallel cylinders, each of which is radially arranged front and back with two transparent reference pieces, the reference piece is marked with a calibration mark, and the positions and directions of the front and back calibration marks correspond; one of the two cylinders is a left and right calibration cylinder, and the other is a front and back calibration cylinder; a left and right level for calibrating the left and right levels is arranged behind the reference piece in the horizontal calibration cylinder, and a front and back level for calibrating the front and back levels is arranged behind the reference piece in the front and back calibration cylinder; a small ball that can move along its inner cavity is arranged in the semicircular canal model; the semicircular canal model is fixed on the cylinder, and when the plane where the user's binocular sight is located is parallel to the plane where the two cylinder axes are located, the semicircular canal model is consistent with the direction of the user's semicircular canal. The present invention allows the two eyes of a person and the calibration marks on the front and back reference pieces in the left and right cylinders to be in a straight line through the principle of three points and one line, ensuring that the user's semicircular canals are consistent in direction with the semicircular canal model. After synchronization, the horizontal position of the head in the left and right directions is calibrated using the left and right level gauges, and the horizontal position of the head in the front and back directions is calibrated using the front and back level gauges, so that the user's head is in a horizontal position for zeroing.

[0011] As an improvement, the semicircular canal model is divided into two left and right semicircular canals, which correspond to the semicircular canals in the left and right ears of the human body respectively, and the movement of the otoliths in the left and right semicircular canals of the human body is respectively interpreted.

[0012] As an improvement, the semicircular canal model is made of a transparent material, so as to facilitate observation of the position of the small ball in the model.

[0013] As an improvement, the level comprises a transparent cylinder, in which liquid is poured, but the liquid does not fill the cylinder, and bubbles are left in the cylinder, and when the bubbles are located in the middle of the cylinder, it indicates that the cylinder is level.

[0014] As a further improvement, a scale line is marked in the middle of the cylinder to facilitate observation of the position of the bubble.

[0015] As another further improvement, the liquid is dark in color, and lining plates with a color contrasting with the liquid are arranged behind the left and right level gauges and at the bottom of the front and rear level gauges, so that the position of the bubble is easier to observe.

[0016] As an improvement, the left and right levels in the left and right calibration cylinders are parallel to the vertical line connecting the two cylinders; the front and rear levels in the front and rear calibration cylinders are parallel to the axis of the cylinders.

[0017] As an improvement, a reflector placed forward and tilted is arranged behind the front and rear level, and the angle between the reflector and the cylinder axis is 45°. Since the front and rear level are placed parallel to the cylinder axis, only the front end of the front and rear level can be seen by direct observation, and the position of the bubble cannot be accurately observed. An oblique light-emitting mirror is arranged to refract light to observe the upper part of the front and rear level.

[0018] As an improvement, it further includes a bracket, and the front and rear ends of the cylinder are connected to the bracket; one of the two cylinders is a fixed cylinder and the other is a movable cylinder; the bracket is provided with a track perpendicular to the cylinder, and the movable cylinder can slide left and right along the track; it also includes a screw rod parallel to the track, and the screw rod is threadedly matched with the movable cylinder. Since the distance between human eyes is different, the movable cylinder is driven by the screw rod to move and adjusted to a suitable distance to adapt to the distance between human eyes.

[0019] As an improvement, a knob is provided at the end of the screw rod to facilitate driving the screw rod to rotate.

[0020] As an improvement, the calibration mark is a crosshair.

[0021] As an improvement, a light-collecting hole is opened on the side wall of the cylinder.

[0022] The invention is beneficial in that the otolith disease treatment device with the above structure and calibration function can calibrate the relative position of the head and the device body so that the positions of the two are synchronized and the direction of the semicircular canal model is consistent with that of the semicircular canal of the human body. After synchronization, the left and right level and the front and back level can be used to adjust the head position to a horizontal level so that the otolith position is zeroed. It is convenient for doctors to intuitively know the position of the otoliths without relying on their own imagination to simulate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0031] like Figure 1-Figure 5 As shown, the present invention includes a semicircular canal model 17 and a calibration device, the calibration device includes two parallel cylinders 1 on the left and right, and a light-collecting hole 14 is opened on the side wall of the cylinder 1. Two transparent reference plates 2 are radially arranged in front and back in each cylinder 1, and calibration marks 3 are marked on the reference plates 2, and the calibration marks 3 are crosshairs. And the positions and directions of the two calibration marks 3 on the front and back correspond; one of the two cylinders 1 is a left-right calibration cylinder, and the other is a front-back calibration cylinder; a left-right level 4 for calibrating the left-right level is arranged behind the reference plate 2 in the horizontal calibration cylinder, and a front-back level 6 for calibrating the front-back level is arranged behind the reference plate 2 in the front-back calibration cylinder. A small ball 18 that can move along its inner cavity is arranged in the semicircular canal model 17; the semicircular canal model 17 is fixed on the cylinder 1, and when the plane where the user's binocular sight is located is parallel to the plane where the axes of the two cylinders 1 are located, the semicircular canal model 17 is consistent with the direction of the user's semicircular canal 19. There are two left and right semicircular canal models 17, which correspond to the semicircular canals 19 in the left and right ears of the human body, respectively. The semicircular canal model 17 is made of a transparent material, and the ball 18 can be made of a dark material.

[0032] The left and right level 4 and the front and rear level 6 have the same structure, but are placed differently. The left and right level 4 in the left and right calibration cylinder is parallel to the vertical line connecting the two cylinders 1; the front and rear level 6 in the front and rear calibration cylinder is parallel to the axis of the cylinder 1. A reflector 7 tilted forward is arranged behind the front and rear level 6, and the angle between the reflector 7 and the axis of the cylinder 1 is 45°. The level includes a transparent cylinder 41, and the cylinder 41 is filled with liquid 42, and the liquid 42 does not fill the cylinder 41. A scale line is marked in the middle of the cylinder 41. The liquid 42 is dark, and a lining plate 5 with a color contrasting with the liquid 42 is arranged behind the left and right level 4 and at the bottom of the front and rear level 6. For example, the liquid 42 is red and the lining plate 5 is green.

[0033] It also includes a bracket 8, and the front and rear ends of the cylinder 1 are connected to the bracket 8; one of the two cylinders 1 is a fixed cylinder 12 and the other is a movable cylinder 13; the fixed cylinder 12 is fixed to the bracket 8. The bracket 8 is provided with a track 9 that is straight with the cylinder 1. The movable cylinder 13 can slide left and right along the track 9; it also includes a screw rod 10 parallel to the track 9, and the screw rod 10 is threadedly matched with the movable cylinder 13. The end of the screw rod 10 is provided with a knob 11 for driving the screw rod 10 to rotate. Any one of the front and rear calibration cylinders and the left and right calibration cylinders is the movable cylinder 13, and the other is the fixed cylinder 12. For the convenience of setting, the screw rod 10 also passes through the fixed cylinder 12, but does not threadably match with it, that is, the rotation of the screw rod 10 has no effect on the fixed cylinder 12.

[0034] When in use, the device is worn on the head using the headband 15 so that both eyes face the end of the cylinder 1 away from the level. First, calibration is started from the human eye 16 on one side of the fixed cylinder 12. When the calibration marks 3 on the two reference plates 2 of the cylinder 1 are seen to overlap, it means that the sight line of the human eye 16 and the fixed cylinder 12 are in the same straight line; the knob 11 is used to drive the screw 10 to adjust the position of the movable cylinder 13 so that the calibration marks 3 on the two reference plates 2 in the movable cylinder 13 seen by the other human eye 16 overlap. At this time, the plane where the sight lines of the two human eyes 16 are located is parallel (overlaps) to the plane where the axes of the two cylinders 1 are located, and the semicircular canal model 17 is consistent with the direction of the semicircular canals 19 of the human body. Of course, the position between the semicircular canal model 17 and the cylinder 1 is set in advance, that is, the positional relationship between the semicircular canal model 17 and the axis of the cylinder 1 is consistent with the positional relationship between the semicircular canals 19 of the human body and the sight line of the person.

[0035] By swinging the head position left and right, the bubble 43 in the left and right level 4 in the left and right calibration cylinder is located in the middle of the cylinder 41; then the head position is shaken back and forth, so that the bubble 43 in the front and rear level 6 in the front and rear calibration cylinder is located in the middle of the cylinder 41; at this time, it is explained that the plane where the human eye sight is located is a horizontal plane, that is, the head is in a horizontal position. At this time, the sphere 18 in the semicircular canal model 17 and the otolith 20 of the human semicircular canal 19 are reset to zero and are all located in the same position. The doctor can judge the position of the otolith 20 in the semicircular canal 19 by the position of the sphere 18 in the model, without relying on one's spatial imagination ability to simulate the position of the otolith 20, making the whole treatment process simpler.

[0036] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
