Description

Technical Field

[0001] This utility model relates to the field of crystalline intraocular lens technology, and in particular to a recording device for the effect of light intensity on arch height. Background Technology

[0002] An intraocular lens (IOL) is a special lens made of synthetic materials, including silicone, polymethyl methacrylate (PMMA), and hydrogel. IOLs resemble the human eye's lens in shape and function, and are lightweight, have high optical performance, are non-antigenic, non-inflammatory, non-carcinogenic, and biodegradable. After cataract surgery, the cloudy lens is removed, and an IOL is implanted inside the eye to replace the original lens, allowing external objects to be focused onto the retina, thus enabling clear vision. During the production of IOLs, the effect of light intensity on the arch height of the IOL is measured and recorded.

[0003] However, existing recording devices for the effect of light intensity on arch height have shortcomings. They are not convenient for effectively adjusting the light intensity, and therefore cannot better detect and record the effect of light intensity on arch height. Therefore, we propose a recording device for the effect of light intensity on arch height to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a recording device for the influence of light intensity on arch height.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A recording device for measuring the effect of light intensity on arch height includes a housing. Inside the housing is a placement mechanism for placing an intraocular lens (IOL). A mounting plate is fixedly connected inside the housing, and several laser rangefinders are fixedly connected to the bottom of the mounting plate. Two ear plates are fixedly connected to the inner walls of both sides of the housing, and a lamp plate is fixedly disposed between two ear plates on the same side. Control boxes are fixedly connected to both sides of the housing, and each control box has a light intensity adjustment mechanism. A computer controller is fixedly connected to one side of the right control box. A power supply unit is fixedly connected to the bottom of the housing.

[0007] As a preferred embodiment of this utility model, the placement mechanism includes a slide plate slidably disposed within the housing, a placement plate fixedly connected to the top of the slide plate, and a plurality of placement slots for placing an intraocular lens for crystalline eyes, the placement slots corresponding to a laser rangefinder.

[0008] As a preferred embodiment of this utility model, guide rails are fixedly connected to the inner walls on both sides of the box, and the slide plate is slidably sleeved within the two guide rails.

[0009] In a preferred embodiment of this invention, the light intensity adjustment mechanism includes a drive motor fixedly connected to the top of the control box, and five resistors fixedly connected to the inner wall of one side of the control box. The five resistors increase in size from top to bottom. A conductive post is electrically connected to one side of each resistor, and a conductive sheet is electrically connected to one end of each conductive post. The same insulating plate is fixedly connected to the upper and lower inner walls of the control box, and all five conductive sheets are fixedly embedded in the insulating plate. A lifting screw is fixedly connected to the output shaft of the drive motor, and a lifting seat is threaded onto the outer side of the lifting screw. A return spring is fixedly connected to one side of the lifting seat, and a moving plate is fixedly connected to one end of the return spring. A connecting plate is fixedly connected to one side of the moving plate, and a conductive sheet is fixedly connected to one side of the connecting plate. The conductive sheet movably abuts against one side of the corresponding conductive sheet.

[0010] In a preferred embodiment of this utility model, a control switch is fixedly connected to the top of the control box. The control switch and the lamp board are electrically connected to the power supply body. The lamp board is connected in parallel with five resistors. The control switch is electrically connected to the second conductive sheet.

[0011] In a preferred embodiment of this invention, both the drive motor and the laser rangefinder are electrically connected to the computer controller.

[0012] In a preferred embodiment of this invention, the same limiting rod is fixedly connected to the upper and lower inner walls of the control box, the lifting seat is slidably sleeved on the outside of the limiting rod, two crossbars are fixedly connected to one side of the lifting seat, and the moving plate is slidably sleeved on the outside of the two crossbars.

[0013] As a preferred embodiment of this utility model, a door is rotatably connected to the front side of the box body, and a handle is fixedly connected to the front side of the door.

[0014] In this invention, a recording device for the effect of light intensity on the arch height is described. The intraocular lens to be tested is placed in the placement slot. When the slot is full, the sliding plate is pushed backward so that the sliding plate and the placement plate slide into the two guide rails and the box. The box door is closed and the control switch is closed. The intraocular lens can be illuminated by the light plate. After the illumination has been performed for a period of time, the arch height of the intraocular lens is measured by a laser rangefinder and recorded and displayed by a computer controller.

[0015] In this invention, a recording device for the effect of light intensity on the arch height is described. The drive motor is activated, which rotates the lifting screw. The lifting screw causes the lifting seat and connecting plate to move downwards. During this downward movement, the second conductive piece is squeezed by the insulating plate, causing the second conductive piece, the connecting plate, and the moving plate to move to the right and squeeze the return spring. When the second conductive piece moves downwards and abuts against the first second conductive piece, the resistance increases sequentially from top to bottom, thus reducing the power transmitted by the lamp board and achieving the purpose of reducing the light intensity. After a period of illumination, the arch height of the intraocular lens is measured using a laser rangefinder. Following the above steps, the second conductive piece continues to move downwards, connecting sequentially to resistors of different sizes, thereby gradually reducing the light intensity. Under different light intensities, the arch height of the intraocular lens can be measured and recorded using a laser rangefinder. By comparing the data, the effect of light intensity on the arch height can be detected.

[0016] This utility model has a reasonable structural design. Through the light intensity adjustment mechanism, the second conductive sheet can be made to abut against different first conductive sheets, thereby allowing the second conductive sheet to be connected to resistors of different sizes, thus changing the light intensity of the lamp board. Under different light intensities, the arch height of the intraocular lens can be measured, recorded, and compared with the data, thereby detecting the effect of light intensity on the arch height.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A recording device for measuring the effect of light intensity on arch height includes a housing 1. The housing 1 contains a placement mechanism for placing an intraocular lens. A mounting plate 13 is fixedly connected inside the housing 1. Several laser rangefinders 14 are fixedly connected to the bottom of the mounting plate 13. Two ear plates 11 are fixedly connected to the inner walls of both sides of the housing 1. A lamp plate 12 is fixedly disposed between the two ear plates 11 on the same side. Control boxes 3 are fixedly connected to both sides of the housing 1. Light intensity adjustment mechanisms 5 are disposed on the control boxes 3. A computer controller 4 is fixedly connected to one side of the right control box 3. A power supply unit 10 is fixedly connected to the bottom of the housing 1.

[0024] Furthermore, refer to Figure 2 As shown, the placement mechanism includes a slide plate 7 that is slidably disposed inside the housing 1. A placement plate 8 is fixedly connected to the top of the slide plate 7. The top of the placement plate 8 has several placement slots 9 for placing the intraocular lens of the crystalline eye. The placement slots 9 correspond to the laser rangefinder 14. Guide rails 6 are fixedly connected to the inner walls on both sides of the housing 1. The slide plate 7 is slidably fitted inside the two guide rails 6.

[0025] Using the above method: Place the intraocular lens to be tested into the placement slot 9. When it is full, push the slide plate 7 backward so that the slide plate 7 and the placement plate 8 slide into the two guide rails 6 and the box 1. Close the box door 2. After the test is completed, pull the slide plate 7 outward to facilitate the picking and placing of the intraocular lens.

[0026] Furthermore, refer to Figure 1-4As shown, the light intensity adjustment mechanism 5 includes a drive motor 501 fixedly connected to the top of the control box 3, and five resistors 505 fixedly connected to the inner wall of one side of the control box 3. The five resistors 505 increase in size from top to bottom. A conductive post 506 is electrically connected to one side of each resistor 505, and a conductive sheet 507 is electrically connected to one end of each conductive post 506. The same insulating plate 508 is fixedly connected to the upper and lower inner walls of the control box 3. All five conductive sheets 507 are fixedly embedded in the insulating plate 508. A lifting screw 502 is fixedly connected to the output shaft of the drive motor 501. A lifting seat 503 is threaded onto the outer side of the lifting screw 502. A reset spring 513 is fixedly connected to one side of the control box 3. A moving plate 511 is fixedly connected to one end of the reset spring 513. A connecting plate 510 is fixedly connected to one side of the moving plate 511. A conductive sheet 509 is fixedly connected to one side of the connecting plate 510. The conductive sheet 509 movably abuts against one side of the corresponding conductive sheet 507. A control switch 15 is fixedly connected to the top of the control box 3. The control switch 15 and the lamp board 12 are electrically connected to the power supply body 10. The lamp board 12 is connected in parallel with five resistors 505. The control switch 15 is electrically connected to the conductive sheet 509. The drive motor 501 and the laser rangefinder 14 are electrically connected to the computer controller 4.

[0027] Using the above scheme: When the control switch 15 is closed, the intraocular lens of the lenticule can be illuminated through the lamp panel 12. After a period of illumination, the arch height of the intraocular lens is measured by the laser rangefinder 14 and recorded and displayed by the computer controller 4. Then, the drive motor 501 is started, which drives the rotation of the lifting screw 502. The lifting screw 502 drives the lifting seat 503 and the connecting plate 510 to move downward. During the downward movement, the conductive sheet 509 is squeezed by the insulating plate 508, causing the conductive sheet 509, the connecting plate 510, and the moving plate 511 to move to the right and squeeze the return spring 513. When the conductive sheet 509 moves downward... When the light source comes into contact with the second conductive sheet 507, the resistance increases sequentially from top to bottom due to the five resistors 505. This reduces the power delivered by the lamp board 12, thereby reducing the light intensity. After a period of illumination, the arch height of the intraocular lens is measured using the laser rangefinder 14. Following the above steps, the conductive sheet 509 continues to move downwards, connecting sequentially with resistors 505 of different sizes, thus reducing the light intensity sequentially. Under different light intensities, the arch height of the intraocular lens can be measured and recorded using the laser rangefinder 14. By comparing the data, the effect of light intensity on the arch height can be detected.

[0028] Furthermore, the same limiting rod 504 is fixedly connected to the upper and lower inner walls of the control box 3. The lifting seat 503 is slidably sleeved on the outside of the limiting rod 504. Two crossbars 512 are fixedly connected to one side of the lifting seat 503. The moving plate 511 is slidably sleeved on the outside of the two crossbars 512, which is conducive to guiding the moving plate 511 and the lifting seat 503, making their movement more stable and smooth.

[0029] Furthermore, a door 2 is rotatably connected to the front of the housing 1, and a handle is fixedly connected to the front of the door 2 to facilitate opening the door 2 for taking out and putting in the intraocular lens.

[0030] In this invention, during use, the intraocular lens to be tested is placed in the placement slot 9. When full, the sliding plate 7 is pushed backward, causing the sliding plate 7 and placement plate 8 to slide into the two guide rails 6 and the housing 1. The housing door 2 is closed, and the control switch 15 is closed. The intraocular lens is then illuminated by the lamp plate 12. After illumination for a period of time, the arch height of the intraocular lens is measured by the laser rangefinder 14 and recorded and displayed by the computer controller 4. Then, the drive motor 501 is started, which drives the rotation of the lifting screw 502. The lifting screw 502 causes the lifting seat 503 and the connecting plate 510 to move downward. During the downward movement, the conductive sheet 509 is squeezed by the insulating plate 508, causing the conductive sheet 509 and the connecting plate to... 510 moves to the right relative to the moving plate 511 and presses the reset spring 513. When the second conductive piece 509 moves down to abut against the first conductive piece 507, the resistance increases sequentially from top to bottom due to the five resistors 505, thus reducing the power transmitted by the lamp board 12 and thereby reducing the light intensity. After a period of illumination, the arch height of the intraocular lens is measured by the laser rangefinder 14. Following the above steps, the second conductive piece 509 continues to move down and connects sequentially with resistors 505 of different sizes, thereby reducing the light intensity sequentially. Under different light intensities, the arch height of the intraocular lens can be measured and recorded by the laser rangefinder 14. By comparing the data, the influence of light intensity on the arch height can be detected.
