[0002] With the continuous development of science and technology, electronic products such as mobile phones and computers are becoming more and more popular, and more and more young children are addicted to these electronic products, resulting in a continuous decline in the eyesight of young children. Some studies have shown that the incidence of myopia in young children is increasing year by year, and the age of onset of myopia is also moving down, that is, more and more young children are suffering from myopia.

[0003] In order to alleviate the symptoms of eyesight, some patients use eyesight treatment equipment or low-intensity laser therapy to alleviate the symptoms of eyesight in order to improve eyesight. Among them, the eyesight treatment equipment or low-intensity laser therapy is to emit light of a certain wavelength to the user's eyes, stimulate the user's fundus cell tissue with light, and achieve the purpose of improving eyesight. However, the diameter of the pupil after contraction of each patient's eye is quite different when it is irradiated by light. The size of the pupil directly affects the energy of the light entering the user's fundus.

DETAILED DESCRIPTION

[0053] The technical solutions of the embodiments of the present application will be described clearly and completely below in combination with the drawings of the present application.

[0055] In combination with Figures 1-3 As shown in the drawings, the myopia precision treatment instrument disclosed by an embodiment of the present application comprises a first treatment mechanism 10, a second treatment mechanism 20, a pupil measurement mechanism 30, a pupil determination mechanism and a main control module (not shown in the drawings), wherein the pupil determination mechanism comprises a scanning mechanism 40 and an adjusting mechanism 50, and the main control module comprises a chip with data acquisition, storage and processing capabilities, such as a single-chip microcomputer chip and the like.

[0056] Specifically, the first treatment mechanism 10 and the second treatment mechanism 20 are used to generate treatment light which can enter the fundus of the user to stimulate the fundus cells of the user to achieve the purpose of improving the vision, and each of the first treatment mechanism 10 and the second treatment mechanism 20 comprises a barrel a and a treatment light source b, the barrel a is a cylindrical member, the two barrels a are arranged at intervals, and the interval between the two barrels a is adjustable, the treatment light source b is arranged at one end of each of the two barrels a, and the pupil measurement mechanism 30 and the scanning mechanism 40 are arranged at the other end of each of the two barrels a, that is, the treatment light source b is arranged at one end of one barrel a, and the scanning mechanism 40 and the pupil measurement mechanism 30 are arranged at the opposite end of the one barrel a, and the treatment light source b is arranged at one end of the other barrel a, and the pupil measurement mechanism 30 and the scanning mechanism 40 are arranged at the opposite end of the other barrel a, the pupil measurement mechanism 30 is used to emit illumination light to the eyes of the user and receive the illumination light reflected by the eyes of the user, the scanning mechanism 40 is used to emit scanning light to the eyes of the user and acquire the scanning light reflected by the eyes of the user, and the treatment light source b is used to generate matched treatment light according to the pupil size information of the user, so that the energy of the treatment light entering the fundus of the user is at a preset value, and the preset value is the optimal energy value E. The adjusting mechanism 50 is connected with the two barrels a, and is used to determine a treatment distance matched with the pupil distance of the user according to the scanning light reflected by the eyes of the user, so that the optical axis of the treatment light generated by the treatment light source b coincides with the eye axis of the user, to achieve the best vision treatment effect, and the adjusting mechanism 50 determines the treatment distance matched with the pupil distance of the user by adjusting the distance between the two barrels a.

[0057] As shown in Figure 3 each of the treatment light sources b comprises a treatment light emitting member b1 and a first circuit board b2, the treatment light emitting member b1 is connected with the first circuit board b2, the first circuit board b2 is connected with a main control module, and the main control module controls the treatment light emitting member b1 to generate treatment light of a certain wavelength through the first circuit board b2. Specifically, each of the first circuit boards b2 covers the end of the corresponding barrel a, and the treatment light emitting member b1 is arranged on the end face of the barrel a, that is, the barrel a is arranged outside the treatment light emitting member b1 and is connected with the first circuit board b2. In the embodiment, the treatment light emitting member b1 is preferably a laser light source, and the wavelength is preferably 400-760 nm, of course, in other embodiments, the treatment light emitting member b1 can also be a scattering light source such as an LED light source.

[0058] In combination with Figure 2 and Figure 3As shown, each pupil measurement mechanism 30 comprises a housing 31, an illumination light source 32, a light splitting piece 33 and a camera assembly 34. The housing 31 is a hollow structure, and a first opening 31a and a second opening 31b are oppositely arranged on the side surface of the housing 31. The housing 31 is connected to the corresponding view tube a through the second opening 31b, and the first opening 31a and the second opening 31b are both used for light passing. The illumination light source 32 is arranged at the first opening 31a of the housing 31 and used for emitting illumination light to the user's eye. The illumination light source 32 comprises an illumination light emitting piece c and a second circuit board d connected to the illumination light emitting piece c. The second circuit board d is connected to the main control module, the main control module controls the illumination light emitting piece c to generate illumination light through the second circuit board d, and the second circuit board d is annular in whole.

[0059] In implementation, the illumination light emitting piece c generates illumination light under the control of the second circuit board d and the illumination light is reflected by the user's eye and then reflected by the light splitting piece 33 and then acquired by the camera assembly 34. The main control module obtains the pupil image according to the illumination light received by the camera assembly 34 and further calculates the pupil diameter size by using the image algorithm.

[0060] Further, the light splitting piece 33 is provided with a reflective film corresponding to a wavelength threshold. When the wavelength of the light exceeds the wavelength threshold, the reflective film can reflect the light; when the wavelength of the light does not exceed the wavelength threshold, the reflective film does not reflect the light. In the embodiment, the light splitting piece 33 is a light splitting sheet, and the reflective film is arranged on the surface of the light splitting sheet. The light splitting sheet is arranged in the housing 31 in an inclined manner, and the light splitting sheet is arranged at an angle of 45 degrees with the horizontal plane as the best. At this time, the light splitting sheet can reflect the light horizontally incident from the reflection side into the light vertically upward. Of course, in other embodiments, the light splitting piece 33 can also be a light splitting prism, and the reflective film is embedded in the light splitting prism, which can avoid the reflective film being exposed to the air for a long time and prolong the service life of the light splitting piece 33.

[0061] Further, the camera assembly 34 comprises a lens barrel 34a, a lens 34b, a filter (not shown), an illuminance sensor 34c and a third circuit board 34d. The third circuit board 34d is arranged at the third opening 31c and covers the third opening 31c, and the third circuit board 34d is connected with the main control module. The illuminance sensor 34c is arranged on the end surface of the third circuit board 34d inside the shell 31. The lens barrel 34a is sleeved outside the illuminance sensor 34c and is fixedly connected with the shell 31. The lens 34b and the filter are both arranged in the lens barrel 34a, and the filter is arranged between the illuminance sensor 34c and the lens 34b. In the embodiment, the illuminance sensor 34c is preferably a near-infrared sensor.

[0062] As shown in Figure 2 , in order to improve the measurement accuracy, a dustproof sheet 35 is further arranged at the first opening 31a of the shell 31. The dustproof sheet 35 can prevent dust and the like from entering the shell 31 through the first opening 31a, thereby affecting the measurement effect.

[0063] As shown in Figure 3 , the scanning mechanism 40 comprises a scanning light source 41 and a scanning sensor 42. The scanning light source 41 and the scanning sensor 42 are both arranged on the second circuit board d, that is, the scanning light source 41 and the scanning sensor 42 share the second circuit board d. The main control module controls the scanning light source 41 through the second circuit board d. The scanning light source 41 can emit a linear scanning light to the user's eye. The scanning sensor 42 can receive the scanning light reflected by the user's eye and output the scanning light information to the adjusting mechanism 50. Here, the linear scanning light refers to a laser with a thin line shape.

[0064] When the linear scanning light irradiates the eye, it can irradiate the sclera outside the pupil or directly irradiate the pupil. When the scanning light irradiates the sclera, the scanning light is reflected more, and at this time, the scanning sensor 42 receives the strongest signal of the scanning light. When the scanning light irradiates the non-central position of the pupil, part of the scanning light can enter the fundus through the pupil, at this time, the reflected scanning light is relatively less, and thus the scanning sensor 42 receives a relatively weak signal of the scanning light. When the scanning light irradiates the central position of the pupil, the pupil diameter is larger at this time, and the scanning light entering the pupil is the most, that is, the scanning sensor 42 receives the weakest signal of the scanning light. Therefore, the position of the pupil can be determined according to the signal strength of the scanning light, that is, whether the eye axis of the user coincides with the optical axis of the treatment light can be determined. In combination with Figure 4 and Figure 5As shown, when determining the interpupillary distance, the scanning light sources 41 in the two scanning mechanisms 40 emit linear scanning light to the corresponding eyes under the control of the main control module, and the main control module simultaneously controls the adjusting mechanism 50 to drive the two scanning mechanisms 40 to move relative to the lateral direction, so that the scanning light scans the pupil area of the user. The linear scanning light is reflected by the user's eyes and received by the scanning sensors 42, which further output the scanning light information to the main control module, which further controls the adjusting mechanism 50 according to the scanning light information, so that the adjusting mechanism 50 adjusts the distance between the two view tubes a until the signal of the scanning light received by the scanning sensor 42 is the weakest. At this time, the distance between the two view tubes a is the optimal interpupillary distance, and the eye axis of the user coincides with the optical axis of the treatment light.

[0065] In this embodiment, the scanning mechanism 40 is arranged at the first opening 31a of the shell 31, that is, the pupil measurement mechanism 30 and the scanning mechanism 40 are integrated, which can reduce the space occupation. The scanning light source 41 obliquely irradiates the user's eyes downward, and the scanning sensor 42 is arranged obliquely upward to receive the scanning light reflected by the user's eyes. At the same time, the scanning light is preferably a laser with a wavelength of 800-1500 nm and a width of less than 1 mm, and the wavelength of 808 nm is the best.

[0066] In combination Figure 3 and Figure 6 As shown, the adjusting mechanism 50 includes a base 51, a guide assembly 52, a first supporting member 53, a second supporting member 54, and a driving mechanism. The first supporting member 53 and the second supporting member 54 are arranged on the base 51 through the guide assembly 52, the first supporting member 53 and the second supporting member 54 are arranged in a spaced manner, and the distance between them is adjustable. The guide assembly 52 is used to limit the moving direction of the first supporting member 53 and the second supporting member 54 during movement, and the first supporting member 53 and the second supporting member 54 can move relative to the base 51 along the guide direction under the action of the guide assembly 52. The first supporting member 53 is used to mount one view tube a, and the second supporting member 54 is used to mount the other view tube a. The driving mechanism is connected with the first supporting member 53 and the second supporting member 54, and is used to drive the first supporting member 53 and the second supporting member 54 to move, so as to change the distance between the first supporting member 53 and the second supporting member 54.

[0067] In implementation, the two view tubes a are respectively mounted on the first supporting member 53 and the second supporting member 54, and the driving mechanism drives the first supporting member 53 and the second supporting member 54 to move, so as to change the distance between them, and further change the distance between the two view tubes a, so as to realize the adjustment of the positions of the two treatment light sources b.

Of course, in other embodiments, the supporting member can not be connected with the view tube a, but can be connected with the housing 31 in the pupil measurement mechanism 30, and the distance between the view tubes a can be adjusted by changing the distance between the pupil distance measurement mechanisms 30.

[0069] As shown in Figure 6 , the guide assembly 52 includes a first guide column 52a and a second guide column 52b, both of which extend along the guide direction and are arranged at intervals, and both ends of the first guide column 52a and the second guide column 52b are respectively installed on the base 51 through the support frames 52c, that is, the first guide column 52a is located between the two support frames 52c, one end of which is connected with the base 51 through the support frame 52c, and the opposite end is connected with the base 51 through the support frame 52c, and the second guide column 52b is also located between the two support frames 52c, one end of which is connected with the base 51 through the support frame 52c, and the opposite end is connected with the base 51 through the support frame 52c.

[0070] Further, the first supporting member 53 is provided with a first guide hole and a second guide hole, and the second supporting member 54 is also provided with a first guide hole and a second guide hole, that is, one end of the first supporting member 53 is movably arranged on the first guide column 52a through the first guide hole, and the opposite end is movably arranged on the second guide column 52b through the second guide hole, and one end of the second supporting member 54 is movably arranged on the first guide column 52a through the first guide hole, and the opposite end is movably arranged on the second guide column 52b through the second guide hole. Of course, in other embodiments, the guide assembly 52 can also use a sliding rail and a sliding block matched with the sliding rail, which can be set according to actual needs.

[0071] As shown in Figure 6 , the driving mechanism is arranged between the first supporting member 53 and the second supporting member 54, which includes a driving motor 55 and a driving gear 56 connected with each other. The first supporting member 53 and the second supporting member 54 are respectively provided with a driving plate 57 extending along the moving direction, and the driving plate 57 is provided with a transmission rack engaged with the driving gear 56.

[0072] In combinationFigures 1-7 The working principle of the myopia precision treatment instrument is as follows:

[0073] First, the scanning light sources 41 in the two scanning mechanisms 40 emit linear scanning light to the corresponding eyes under the control of the main control module, and the linear scanning light is reflected by the user's eyes and received by the scanning sensors 42. The scanning sensors 42 further output the scanning light information to the main control module, and the main control module controls the adjusting mechanism 50 according to the scanning light information. The adjusting mechanism 50 further adjusts the distance between the two view tubes a until the signal of the scanning light received by the scanning sensor 42 is the weakest. At this time, the distance between the first view tube a and the second view tube a is the treatment distance matched with the user's pupil distance.

[0074] Secondly, the two treatment light sources b generate treatment light of a certain power under the control of the main control module, which passes through the corresponding view tube a, the light splitting piece 33 and the first opening 31a in turn to the user's eyes, and then irradiates the fundus after passing through the pupil, stimulates the fundus cells, and produces the pupil light reflex phenomenon, that is, the pupil phenomenon. When the user's pupil produces the pupil phenomenon, the pupil will contract, that is, the diameter of the pupil changes (the pupil size is usually distributed between 2.0-7.0mm), which further causes the treatment light entering the human eye to decrease, and finally causes the energy of the treatment light entering the fundus of the human eye to fail to reach the expected optimal energy value E. For example, when the power value of the treatment light is 2mW, the energy distribution range of the treatment light on the user's fundus is 0.13-1mW. Therefore, it is necessary to dynamically adjust the energy of the treatment light according to the pupil size to make the energy of the treatment light entering the user's fundus reach the optimal energy value E.

[0075] Thirdly, the illumination light source 32 generates illumination light under the control of the main control module and irradiates the user's eyes. The reflected illumination light passes through the dustproof sheet 35 and then is reflected by the light splitting piece 33. The illumination light is received by the illumination light sensor 34c in turn through the lens 34b and the light filter. The illumination light sensor 34c sends the illumination light information to the main control module. The main control module can further obtain the change of the pupil when the user's eyes produce the pupil phenomenon, that is, obtain the pupil image, and calculate the pupil diameter size R through image algorithm.

[0076] Finally, the pupil area S is calculated according to the pupil diameter size R, and the laser irradiance I is calculated according to the optimal value of light energy E, wherein,

[0077] S=π(R / 2) 2

[0078] I=E / S;

[0079] Further, by adjusting the current to adjust the treatment light source, the radiation intensity of the treatment light is I, and the energy of the light received by the fundus of the user is kept at the optimal value E, so as to achieve the best treatment effect.

[0080] Further, the pupil diameter size is obtained and it is determined whether the pupil diameter size changes. If the pupil diameter size does not change, the treatment continues until it ends. Otherwise, the treatment light is dynamically adjusted according to the pupil diameter size, so that the energy of the light received by the fundus of the user is kept at the optimal value E.

[0081] The application can dynamically adjust the energy of the treatment light according to the pupil size of the user, so that the energy of the light received by the fundus of the user is kept at the optimal value, thereby improving the treatment effect of vision.
