[0023] Reference Figure 1-3 As shown, it is a preferred embodiment provided by the utility model.

[0024] A device for detecting the moving position of an electric medical device comprises a light-emitting assembly 1, a moving disk 2, a stationary disk 3 and a photosensitive assembly 4, wherein the moving disk 2 is driven by the electric medical device, the photosensitive assembly 4 is used for sensing light signals and performing signal processing, the light-emitting assembly 1, the moving disk 2, the stationary disk 3 and the photosensitive assembly 4 are assembled and arranged in sequence, the light-emitting assembly 1 comprises a plurality of light-emitting bodies 11, the light-emitting bodies 11 are used for emitting light, the photosensitive assembly 4 comprises a plurality of photosensitive sensors 41, and each photosensitive sensor 41 is arranged in a one-to-one correspondence with each light-emitting body 11; the moving disk 2 has a plurality of moving holes 21, the stationary disk 3 has a plurality of stationary holes 31, the moving holes 21 and the stationary holes 31 are arranged in an overlapping or staggered manner, and the moving holes 21 and the stationary holes 31 are arranged to be light-transmissive.

[0025] In the above-mentioned detection device for the moving position of the electric medical device, when the electric medical device is operating, the light-emitting assembly 1 and the photosensitive assembly 4 are respectively in the starting state, and the movement of the electric medical device causes the moving disk 2 to be arranged in rotation. During the rotation of the moving disk 2, when the moving hole 21 coincides with the static hole 31, the light emitted by the light-emitting body 11 passes through the moving hole 21 and the static hole 31 and is sensed by the photosensitive sensor 41 as a light signal. The photosensitive assembly 4 determines the movement direction of the electric medical device and the rotation angle of the moving disk 2 according to the effective order of the light signals sensed by the photosensitive sensor 41, thereby calculating the movement distance and position of the electric medical device. In this way, the detection device has a small size and is suitable for electric medical devices with high integration and small assembly space. The movement position is determined based on the light signal, and the movement position determination accuracy is high, which is convenient for the use of the electric medical device and effectively improves the safety of the use of the electric medical device.

[0029] Furthermore, the dynamic focusing sheet completely fills the dynamic hole 21 , so that the light emitted by the light-emitting body 11 can only be transmitted outward through the dynamic focusing sheet, which plays a light-cutting role, avoids interference with the light sensing of the photosensor 41 , and improves the detection accuracy of the photosensor 41 .

[0030] The dynamic micro-facet is hexagonal in shape, and the dynamic light-emitting surface is arranged in an arched arc shape.

[0031] The dynamic focusing sheet has a dynamic reflecting surface, which surrounds the dynamic light emitting surface, and is arranged in a flared shape along the direction away from the dynamic light emitting surface. The dynamic reflecting surface is arranged in a frustum shape, and the dynamic reflecting surface is used to reflect light; in this way, under the action of the dynamic reflecting surface, a focusing effect is achieved.

[0032] The detection device for the moving position of the electric medical device includes multiple static focusing plates, each static focusing plate is arranged in a one-to-one correspondence with each static hole 31, the static focusing plate is installed on the static disk 3, and the static hole 31 is embedded in the static focusing plate, the static focusing plate is arranged in a light-transmitting manner, and the static focusing plate has a static light-incoming surface and a static light-emitting surface.

The static light-emitting surface has multiple static micro-surfaces, and each static micro-surface is arranged in a flat and docked manner, and each static micro-surface is used to focus and cut off light.

[0033] In this way, under the focusing effect of the static focusing sheet, the light of the light emitting body 11 is prevented from being scattered to the photosensor 41, thereby preventing interference with the light induction of the photosensor 41 and improving the detection accuracy of the photosensor 41.

[0034] Furthermore, the dynamic focusing sheet completely fills the dynamic hole 21 , so that the light emitted by the light-emitting body 11 can only be transmitted outward through the static focusing sheet, which plays a light-cutting role, avoids interference with the light sensing of the photosensor 41 , and improves the detection accuracy of the photosensor 41 .

[0035] Furthermore, under the dual focusing effect of the dynamic focusing sheet and the static focusing sheet, the detection accuracy of the photosensor 41 is greatly improved.

[0041] During one unidirectional rotation of the moving disk 2, z photosensors 41 are effective in turn, and the movement distance of the electric medical device is L. L is calculated as: L=2πR*z / m, where R is the radius of the pitch circle of the moving disk 2 and the rack 5, and m is the coefficient.

[0042] The coefficient m=n*(n+1), or the coefficient m=n*n.
