Description
Technical Field
The invention relates to an otolithiasis treatment instrument, in particular to an otolithiasis treatment instrument with a calibration function
Background
Otolithiasis, also known as benign paroxysmal positional vertigo, refers to vertigo and nystagmus with transient paroxysmal attacks occurring when the head moves rapidly to a specific head position.
The vestibule is an organ responsible for the sense of balance, and includes three semicircular canals 19 that play an important role in maintaining the balance of the body, and as shown in fig. 6, the semicircular canals 19 are connected to the cochlea 21. The three semicircular canals, i.e., the upper semicircular canal, the rear semicircular canal, and the outer semicircular canal, have a structure in which they intersect at right angles to each other. The vestibule also includes an otolith device having the following configuration: many short hairs grow vigorously, and fine otoliths 20 are provided at the tip of the short hairs, and the shaking of the otoliths 20 is used to sense the gravity and the linear acceleration. When the head is moved, lymph in the three hemivessels also flows, and the hair cells produce nerve stimulation to transmit signals to the brain. The flow of lymph in one semicircular canal corresponding to the direction of movement of the head is stronger than the flow in the other two semicircular canals, and therefore the brain recognizes the rotation of the head. In this way, the brain can recognize the rotation of the head and the linear motion and acceleration of the body by utilizing the functions of the vestibule and the three semicircular canals, and can perform an operation of maintaining the balance of the body.
For various reasons, the otolith 20 may float inside the semicircular canal 19 out of its original position, and the otolith 20 may irritate the semicircular canal 19 to cause vertigo. Therefore, the dizzy can be completely eliminated by taking out the otolith entering the semi-diameter tube by any method.
In the conventional method for removing the otolith 20 from the semicircular canal 19, the head of the patient is moved forward, backward, leftward and rightward, and the otolith 20 is moved in the semicircular canal 19 and finally discharged from the opening of the semicircular canal.
The method requires doctors to have better anatomical foundation and space imagination capability, needs certain experience and technology and has higher operation difficulty.
Patent 201420752896.4 discloses an otolithiasis treatment device, which simulates the position of the actual otolith in the semicircular canal by the otolith in the model through simulating the semicircular canal of the human body, so that the otolith is visible and the treatment difficulty is reduced.

A small ball 18 which can move along the inner cavity of the semicircular pipe model 17 is arranged in the semicircular pipe model 17; the semicircular canal model 17 is fixed on the barrel body 1, and when a plane where the sight lines of the eyes of a user are located is parallel to a plane where the axes of the two barrel bodies 1 are located, the semicircular canal model 17 is consistent with the semicircular canal 19 of the user in direction. The semicircular canal models 17 are left and right and respectively correspond to semicircular canals 19 in left and right ears of a human body. The semicircular canal former 17 is made of a transparent material, while the bead 18 can be made of a dark material.
The left and right levels 4 are identical to the front and rear levels 6, but are placed differently. The left and right gradienters 4 in the left and right calibration cylinders are parallel to the vertical connecting line of the two cylinders 1; the front and rear gradienters 6 in the front and rear calibration cylinders are parallel to the axis of the cylinder body 1. A reflector 7 which is inclined forwards is arranged behind the front and rear gradienters 6, and the included angle between the reflector 7 and the axis of the cylinder 1 is 45 degrees. The level comprises a transparent cylinder 41, which cylinder 41 is filled with a liquid 42, and the liquid 42 does not fill the cylinder 41. The middle of the cylinder 41 is marked with scale marks. The liquid 42 has a dark color, and lining plates 5 for contrasting the color of the liquid 42 are provided behind the left and right levels 4 and at the bottoms of the front and rear levels 6. For example, the liquid 42 is red and the backing plate 5 is green.
The device also comprises a bracket 8, and the front end and the rear end of the cylinder body 1 are connected with 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 with the bracket 8.
