Detailed implementation mode

[0024] Example 1

[0025] An auxiliary reduction instrument for otolithiasis, comprising: a head fixing assembly 1, an adjusting device 3, and a simulation device 4; the outer wall of the head fixing assembly 1 is connected to the adjusting device 3 through a connecting rod 2 provided, and the end of the adjusting device 3 is detachably installed with the simulation device 4, and the angle of the simulation device 4 is adjusted through the adjusting device 3 to simulate the positional relationship of the semicircular canals of the human body in the brain.

[0026] The simulation device 4 includes: a support block 44, a front tube 41, a rear tube 42, and a horizontal tube 43; the support block 44 has a hollow structure, and the front tube 41, the rear tube 42, and the horizontal tube 43 are fixedly installed on the side end surface of the support block 44; the front tube 41, the rear tube 42, and the horizontal tube 43 are arranged according to the positions of the human semicircular canals. A liquid addition hole 45 is fixedly provided at the upper end of the support block 44. Through the provided liquid addition hole 45, medical staff can add corresponding liquids to the interior to simulate the liquid environment in the human body; the support block 44, the front tube 41, the rear tube 42, and the horizontal tube 43 are hollow transparent structures. The transparent setting allows medical staff to observe the position of the magnetic ball 47 at any time. After the position of the magnetic ball 47 no longer moves, the position of the patient can be changed again to perform otolith reduction treatment. Specifically, magnetic balls 47 are respectively arranged in the three tubes, and a magnet block 46 is detachably installed on one side of the connection between the front tube 41, the rear tube 42, the horizontal tube 43, and the support block 44; the magnet blocks 46 provided at different positions control the fixation and movement of the magnetic balls 47 inside the front tube 41, the rear tube 42, and the horizontal tube 43; through the externally placed simulation structure, the actual position of the internal otoliths can be simulated, enabling medical staff to intuitively see the situation of the internal otoliths and facilitating direct reduction treatment. At the same time, magnet blocks 46 are provided on the support block 44, and magnetic balls 47 are respectively arranged at the temporal parts of the front tube 41, the rear tube 42, and the horizontal tube 43. The magnetic balls 47 are used to simulate the otoliths in the human semicircular canals. At the same time, magnet blocks 46 and magnetic balls 47 are arranged at different positions, and different magnetic balls 47 can be released through the magnet blocks 46 at different positions to simulate the positions where the otoliths fall into the semicircular canals at different positions, and the patient can be treated through external simulation;

[0027] Based on the structure in the above embodiment, at the same time, a liquid medium is filled inside the support block 44, the front tube 41, the rear tube 42, and the horizontal tube 43 to simulate the liquid density and resistance of the human semicircular canals through the liquid medium; the liquid medium can be a gel liquid with fluidity, brine with high density, or other liquids that can make the magnetic ball 47 slowly fall; to simulate the real situation in the human body; the relationship between the gravity and buoyancy of the liquid medium and the magnetic ball 47 can be obtained by those skilled in the art through a limited number of experiments, and no further elaboration will be made here.

[0028] Specifically, when in use, the front tube 41, the rear tube 42, and the horizontal tube 43 in this embodiment respectively correspond to the anterior semicircular canal, the posterior semicircular canal, and the horizontal semicircular canal of the human body; first, medical staff judge which semicircular canal the otolith is in according to the corresponding position change experiment, and then perform the corresponding reduction treatment. During the treatment, according to the judgment result, take the magnet block 46 at the corresponding position, release the magnetic ball 47, and then the simulation observation and reduction can be carried out according to the actual situation.

[0029] Embodiment 2

[0030] In this embodiment, based on the adjusting device 3 described in Embodiment 1, the angle of the simulation device 4 can be adjusted through the provided adjusting device 3, so that it can fit more closely to the position of the semicircular canals inside the human body, enabling the device to more closely simulate the real situation of the human body during the simulation process. Specifically, the adjusting device 3 includes a cross support plate 31, a horizontal arc plate 32, a vertical arc plate 33, and an adjusting rod 34. An extension block 311 is fixedly arranged at the end of the cross support plate 31 perpendicular to the plate surface. The horizontal arc plate 32 and the vertical arc plate 33 are movably installed inside the extension block 311. Arc grooves 35 are provided on the horizontal arc plate 32 and the vertical arc plate 33. The horizontal arc plate 32 and the vertical arc plate 33 are installed crosswise and perpendicularly. The end of the adjusting rod 34 is movably installed in the middle of the cross support plate 31 through a provided ball head 341. The end of the adjusting rod 34 passes through the intersection position of the horizontal arc plate 32 and the vertical arc plate 33 and extends outward to be connected to a support block 44. By controlling the rotation of the horizontal arc plate 32 and the vertical arc plate 33, the position of the adjusting rod 34 is controlled to control the position of the simulation device 4. When in use, directly rotating the angles of the horizontal arc plate 32 and the vertical arc plate 33 can directly adjust the position of the adjusting rod 34, and further adjust the position of the simulation device 4. The horizontal arc plate 32 adjusts the up and down angles, and the vertical arc plate 33 adjusts the left and right rotation angles. Their relative position relationship can adjust the simulation device 4 to any position based on the rotation pad of the adjusting rod 34. At the same time, in this embodiment, the detachable manner between the adjusting device 3 and the simulation device 4 can be an insertion method. Specifically, the end of the adjusting rod 34 is inserted into the support block 44 of the simulation device 4. It can also be a threaded rotation method. Specifically, the simulation device 4 can be rotatably installed on the adjusting rod 34 of the adjusting device 3.

[0031] In addition, in this embodiment, at the connection of the horizontal arc plate 32, the vertical arc plate 33 and the support block 44, an angle scale 312 is provided on the surface of the support block 44. By means of the provided angle scale 312, medical staff can directly calculate the position relationship at this time, so as to correct the position of the simulation device 4 (the calculation method belongs to the conventional calculation in this field and has no particularity, so no more description will be given here). At the same time, indicating arrows 331 are provided on the horizontal arc plate 32 and the vertical arc plate 33 to indicate the current angle, and the connection of the horizontal arc plate 32, the vertical arc plate 33 and the support block 44 is a damping rotating shaft connection; in this way, medical staff can directly perform rotational adjustment, which is convenient and fast; however, this method still has certain defects. Specifically, during use, when the patient rotates or touches the horizontal arc plate 32 and the vertical arc plate 33, the position of the simulation device 4 will change, thus failing to achieve the simulation effect; therefore, to solve the above technical problems, bolts (not shown in the figure) can be added outside the extension block 311 for further fixing after adjustment, so as to solve the above technical problems. However, this method requires medical staff to perform rotational fixing again, but it can well solve the above technical problems.

[0032] Embodiment 3

[0033] In this embodiment, based on the head fixing assembly 1 described in Embodiment 1, the entire device can be worn on the patient's head through the provided head fixing assembly 1. Specifically, the head fixing assembly 1 includes an adjustment knob 11, a telescopic belt 12, and an arc-shaped fixing plate 13; the connecting plate is fixedly installed on the arc-shaped fixing plate 13, and a soft cushion layer can be installed on the inner wall of the arc-shaped fixing plate 13 to protect the patient's head and reduce compression. The telescopic belt 12 is fixedly connected to the end face of the arc-shaped fixing plate 13, and the telescopic belt 12 is connected to the inside of the adjustment knob 11; by controlling the forward and reverse rotation of the adjustment knob 11 to tighten and release, the telescopic belt 12 is a plastic soft telescopic belt 12 (similar to the tie strap in the prior art). At the same time, teeth are provided on the telescopic belt 12, and teeth are also provided inside the adjustment knob 11. The principle of scaling through the adjustment knob 11 is the prior art, which is the same as the structure of controlling the rotation and scaling of the rear end of the helmet to adapt to the heads of different patients, so no more description will be given here.
