Description

Technical Field

[0001] This invention relates to the field of eyeball measurement technology, specifically to an automatic eyeball protrusion measurement device. Background Technology

[0002] Eye exophthalmometry is a key piece of equipment in ophthalmic clinical diagnosis, used to measure the degree of eyeball protrusion relative to the lateral orbital margin. It provides data support for screening diseases such as hyperthyroid exophthalmos and orbital tumors. Currently, the most widely used type in clinical practice is the manual exophthalmometer. When using it, the patient must first keep their head upright and in a fixed posture. The operator holds the device with both hands and precisely aligns the support feet on both sides of the device with the bone of the lateral orbital margin on both sides of the patient to establish the measurement reference plane. Then, the operator manually adjusts the vernier slider of the device, slowly pushing the detection component at the front of the slider closer to the corneal apex until the detection component makes slight contact with the corneal surface. Finally, the value on the vernier scale is read. By calculating the distance difference between the detection component and the support feet of the lateral orbital margin, the eyeball protrusion data is obtained.

[0003] Current eyeball protrusion measurement devices require manual calibration and positioning by the operator. Furthermore, the grip angle and support force vary among different operators, and patients have individual characteristics of orbital morphology, which can easily lead to deviations in the positioning of the reference plane of the outer edge of the orbit, thereby reducing the efficiency and accuracy of the measurement.

[0004] To address the above issues, an automatic eyeball protrusion measurement device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic eyeball protrusion measurement device. By using this invention, the problems in the above-mentioned background are solved: when using an eyeball protrusion measurement device, the operator needs to manually calibrate and position it; at the same time, different operators have different grip angles and support foot contact force; and patients have individual characteristics of orbital shape, which can easily lead to positioning deviation of the reference plane of the outer edge of the orbit, thereby reducing the efficiency and accuracy of measurement.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic eyeball protrusion measuring device includes a fixed frame, a controller on one side of the fixed frame, and a rubber pad fixedly connected to the other side of the fixed frame. An elastic connecting component is provided on one side of the fixed frame. A visual detection component is disposed within the fixed frame. Two adjusting alignment components are disposed opposite each other within the visual detection component. Each adjusting alignment component contains a driving component. A spiral limiting component is rotatably disposed within the driving component. A first measuring component is disposed within the spiral limiting component and is slidably connected to the driving component. A positioning component is disposed within the spiral limiting component and is engaged with the driving component. Two second measuring components are disposed opposite each other on one side of the visual detection component. A pushing component is disposed on one side of the spiral limiting component. A linkage component is disposed on one side of each of the two second measuring components, and the pushing component and the linkage component are engaged.

[0007] Furthermore, the elastic connection assembly includes two connecting plates fixedly connected to both sides of the fixed frame, and an elastic band is fixedly connected to one side of each connecting plate.

[0008] Furthermore, the visual detection component includes a vertical rod fixedly connected within a fixed frame, two horizontal rods fixedly connected to both sides of the vertical rod, and a visual sensor installed on one side of the vertical rod.

[0009] Furthermore, the adjustment alignment assembly includes a dual-output electric push rod installed inside the crossbar. The two movable ends of the dual-output electric push rod are respectively fixedly connected to a first slider and a second slider, and both the first slider and the second slider are slidably connected to the crossbar.

[0010] Furthermore, the driving component includes a motor installed inside the first slider, the output end of the motor is fixedly connected to a turntable, the turntable is rotatably connected to the first slider, a plurality of connecting rods are fixedly connected to one side of the first slider, a support frame is fixedly connected to one end of the connecting rods, and a plurality of slots are evenly provided on the inner wall of the support frame.

[0011] Furthermore, the spiral limiting assembly includes a rotating plate rotatably connected within the support frame, the rotating plate having a spiral groove extending through it, and a plurality of storage slots evenly distributed around the outer circumference of the rotating plate.

[0012] Furthermore, the first measuring component includes a third slider slidably connected within the turntable, a mounting column fixedly connected to one side of the third slider, a rotating sleeve rotatably connected to the outer wall of the mounting column, a laser sensor mounted at one end of the mounting column, and the rotating sleeve rollingly connected to the spiral groove.

[0013] Furthermore, the positioning component includes several tilting frames rotatably connected within the rotating plate. Two first springs are fixedly connected to the inner wall of the tilting frames, and the other ends of the two first springs are fixedly connected to the inner wall of the storage groove. The tilting frames are engaged with the slots.

[0014] Furthermore, the second measuring component includes a first fixed seat fixedly connected to one side of the crossbar, a second fixed seat fixedly connected to one side of the second slider, a lifting plate slidably connected inside both the first and second fixed seats, two second springs fixedly connected to the inner walls of both the first and second fixed seats, one end of each of the two second springs being fixedly connected to both sides of the lifting plate, and an mounting block fixedly connected to one side of one of the lifting plates, with an infrared sensor mounted on one side of the mounting block.

[0015] Furthermore, the pushing assembly includes an L-shaped push rod fixedly connected to one side of the rotating plate, with a roller rotatably connected to one end of the L-shaped push rod; The linkage component includes a first fixed rod and a second fixed rod respectively fixedly connected to one side of the two lifting plates. A sliding rod is slidably connected to the outer wall of the second fixed rod. A lifting frame is fixedly connected to one end of the first fixed rod and the sliding rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By coordinating the visual inspection component and the adjustment alignment component, the visual sensor can identify the feature points of the eyeball and eye socket, guide the dual-output electric push rod to adjust the position of the measurement component, achieve automatic and accurate alignment of the eyes, avoid the positioning deviation of manual operation, and improve measurement efficiency and accuracy. Through the cooperation between the drive component and the spiral limiting component, the laser sensor can be driven by the motor to move spirally along the spiral groove to perform all-round multi-point dynamic measurement of the surface of the eyeball, which makes up for the one-sidedness of single-point measurement data and ensures the comprehensiveness and accuracy of the measurement results. By cooperating with the positioning component and the driving component, the snap-fit ​​structure of the tilt frame and the slot can be used to achieve a precise 90-degree indexing rotation of the spiral limiting component, change the measurement path of the laser sensor, reduce measurement blind spots, and achieve 360-degree coverage measurement of the eyeball surface. By coordinating the push components and linkage components, the rotating plate can drive the L-shaped push rod to push the lifting frame, and simultaneously drive the infrared sensor to rise and fall, so as to dynamically adapt and measure different heights of the outer edge of the orbit, and adapt to the differences in orbital shape of different patients. By combining laser and infrared sensors, distance data between the corneal apex and the outer edge of the orbit can be collected in a non-contact detection manner. Combined with the controller's difference calculation function, the eyeball protrusion value is automatically output, reducing human reading errors. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] To address the technical challenges of using ocular protrusion measurement devices, such as the need for manual calibration and positioning by the operator, variations in grip angle and support force among operators, and individual differences in patient orbital morphology leading to deviations in the positioning of the lateral orbital margin reference plane, which reduce measurement efficiency and accuracy, the following measures are proposed. Figures 1-10 As shown, the following preferred technical solutions are provided: like Figures 1-3 As shown, an automatic eyeball protrusion measuring device includes a fixed frame 1, which can support and fix various components. The fixed frame 1 is made of a rigid material with light-shielding properties, which combines structural strength and light-shielding performance. It can prevent external light from penetrating or forming stray reflections inside the device, thus preventing it from affecting the subsequent acquisition of images of the eyeball and eye socket and the measurement of distance, and ensuring the reliability of the measurement data. A controller 11 is provided on one side of the fixed frame 1. The controller 11 can control various electrical devices and display the measurement value of eyeball protrusion. A rubber pad 12 is fixedly connected to the other side of the fixed frame 1. The rubber pad 12 can conform to the skin around the human eye socket, play a buffering role, and increase the fit between the device and the human body, thereby improving the stability and comfort during measurement.

[0021] A flexible connecting component 2 is provided on one side of the fixed frame 1. This component adapts to the head shape and contours of different users, adjusting the relative position of the device and the eyes to provide a basis for subsequent measurements. A visual detection component 3 is installed inside the fixed frame 1. During detection, the visual detection component 3 acquires real-time image information of the eyeball and eye socket, visually recognizing the shape and position of the eyeball to assist in judging the alignment accuracy of the measurement structure and the effectiveness of the measurement area. Two adjustment alignment components 4 are arranged opposite each other within the visual detection component 3. Each adjustment alignment component 4 contains a driving component 5, and a spiral limiting component 6 is rotatably installed within the driving component 5. A first measuring component 7 is installed within the spiral limiting component 6. The first measuring component 7 measures the distance between itself and the eyeball. The first measuring component 7 is slidably connected to the driving component 5. The driving component 5 drives the first measuring component 7 to rotate. During the rotation of the first measuring component 7, the spiral limiting component 6 limits its rotation, enabling a helical rotational motion. This allows for comprehensive, multi-point dynamic measurement of the eyeball surface, avoiding the limitations of single-point measurement and improving the comprehensiveness of the measurement data. Figure 6 As shown, a positioning component 8 is provided inside the spiral limiting component 6. The positioning component 8 is engaged with the driving component 5. Two second measuring components 9 are arranged opposite each other on one side of the visual detection component 3. The second measuring components 9 can measure the distance between themselves and the outer edge of the eye socket.

[0022] In use, the patient places the fixing frame 1 on the corresponding position of the eye using the elastic connecting component 2. At this time, the rubber pad 12 fits against the patient's eye socket. Then, the operator makes a fine adjustment to the position of the fixing frame 1 so that its horizontal position is consistent with the horizontal position of the patient's two eyeballs. At this time, the visual detection component 3 detects the position of the patient's cornea and the outer edge of the eye socket, respectively. The controller 11 causes the adjustment alignment component 4 to slide the first measuring component 7 and the second measuring component 9 on the limiting structure within the visual detection component 3. This makes one set of the first measuring component 7 and the second measuring component 9 correspond to the position of the patient's left eyeball and the outer edge of the left eye socket, respectively, and the other set of the first measuring component 7 and the second measuring component 9 correspond to the position of the patient's right eyeball and the outer edge of the right eye socket, respectively. This can achieve synchronous and accurate alignment of the left and right eyeballs with the corresponding outer edges of the eye sockets. Compared with the disadvantages of low accuracy and low efficiency of manual alignment in the existing technology, it can achieve automated alignment of the protrusion of both eyeballs, improving the accuracy and efficiency of the measurement.

[0023] After the first measuring components 7 and the second measuring components 9 are aligned, the controller 11 causes the drive component 5 to rotate the first measuring component 7 in the forward direction. During the forward rotation of the first measuring component 7, the spiral limiting component 6 limits the rotation of the first measuring component 7 in a spiral manner, thereby synchronously collecting multi-point distance data. Compared with the shortcomings of single-point measurement, partial data and susceptibility to human operation in the existing technology, it can obtain more comprehensive eyeball protrusion data and improve the accuracy of the measurement results.

[0024] Simultaneously, due to the dead angle in the limiting path of the spiral limiting component 6, the controller 11 causes the drive component 5 to rotate the first measuring component 7 in the reverse direction, resetting the first measuring component 7 to its initial position. Then, the drive component 5 rotates the first measuring component 7 in the reverse direction again by 90 degrees, causing the spiral limiting component 6 to rotate 90 degrees within the drive component 5. During the rotation of the spiral limiting component 6, several positioning components 8 rotate synchronously, compressing the elastic structures within the positioning components 8. After the first measuring component 7 rotates 90 degrees in the reverse direction again, the elastic structures within the positioning components 8 reset, allowing the positioning components 8 to re-engage with the drive component 5. Subsequently, the controller 11 causes the drive component 5 to... The first measuring component 7 is rotated forward again by component 5, allowing it to perform multi-point distance measurements again. Then, the first measuring component 7 is rotated in the opposite direction by the controller 11, allowing it to return to its initial position. This process is repeated four times to achieve a 360-degree path adjustment. This changes the path of the spiral limiting component 6, allowing the detection position of the first measuring component 7 to cover the surface of the eyeball from multiple directions. This enables multi-point measurement of eyeball protrusion and the acquisition of complete data. Compared with the shortcomings of existing technologies, such as numerous blind spots and insufficient data integrity, this method reduces measurement dead zones and further improves the comprehensiveness and accuracy of eyeball protrusion measurement data.

[0025] A pushing component 10 is provided on one side of the spiral limiting component 6, and a linkage component 20 is provided on one side of each of the two second measuring components 9. The pushing component 10 and the linkage component 20 are in contact. By pushing the linkage component 20 to move up and down, the second measuring component 9 can be moved up and down, so as to realize multi-point dynamic measurement of the outer edge of the eye socket, thereby adapting to the height difference of the outer edge of the eye socket of different users and improving the accuracy of measurement.

[0026] By using the controller 11, the drive component 5 drives the first measuring component 7 to rotate 90 degrees in the opposite direction. After the spiral limiting component 6 rotates 90 degrees within the drive component 5, it drives the push component 10 to rotate 90 degrees as well. This causes the push component 10 to push the linkage component 20 downward and simultaneously drive the second measuring component 9 downward. When the controller 11 causes the drive component 5 to drive the first measuring component 7 to rotate in the opposite direction again to an angle of 270 degrees, the push component 10 can push the linkage component 20 upward and simultaneously drive the second measuring component 9 upward. This allows for dynamic measurement of the second measuring component 9 moving up and down while the first measuring component 7 and the spiral limiting component 6 rotate, forming a dynamic adaptation measurement for different height positions of the lateral edge of the orbit. This adapts to different patients and yields more accurate measurement data.

[0027] Then, through the controller 11, the minimum value measured by the first measuring component 7 is the distance between the protruding position of the eyeball and the first measuring component 7. The peak point with the largest echo intensity measured by the second measuring component 9 is the distance between the outer edge of the orbit and the second measuring component 9. The difference between the distance between the protruding position of the eyeball and the first measuring component 7 and the distance between the outer edge of the orbit and the second measuring component 9 is the measured value of the protrusion of the eyeball.

[0028] like Figure 1 As shown, the elastic connection component 2 includes two connecting plates 21 fixedly connected to both sides of the fixed frame 1. An elastic band 22 is fixedly connected to one side of each connecting plate 21. The elastic band 22 can adapt to the differences in head shape and size of different users, providing stable and adjustable wearing tension, so that the fixed frame 1 always maintains a stable relative position with the eyes, avoiding displacement of the device due to slight head shaking or posture changes during the measurement process. At the same time, it takes into account wearing comfort and reduces the pressure on the scalp, laying a reliable foundation for the subsequent accurate alignment and measurement of the eyeball and the outer edge of the eye socket.

[0029] like Figure 3 and Figure 4 As shown, the visual inspection component 3 includes a vertical rod 31 fixedly connected to the fixed frame 1, two horizontal rods 32 fixedly connected to both sides of the vertical rod 31, and a visual sensor 33 installed on one side of the vertical rod 31.

[0030] like Figure 4 , Figure 5 and Figure 7 As shown, the adjustment alignment component 4 includes a dual-output electric push rod 41 installed inside the crossbar 32. The two movable ends of the dual-output electric push rod 41 are respectively fixedly connected to a first slider 42 and a second slider 43. Both the first slider 42 and the second slider 43 are slidably connected to the crossbar 32. The visual sensor 33 can acquire images of the contours of both eyes and the outer edge of the orbit in real time, accurately identify the corneal apex and the bone feature points of the outer edge of the orbit, and transmit the data to the controller 11. This guides the adjustment alignment component 4 to drive the measurement structure to complete the automatic alignment. At the same time, the light-blocking performance of the fixed frame 1 is used to improve the image clarity and ensure the accuracy of positioning and measurement.

[0031] like Figures 5-8 and Figure 10 As shown, the drive assembly 5 includes a motor 51 installed in the first slider 42. The motor 51 has a self-locking function. The output end of the motor 51 is fixedly connected to a turntable 52. The turntable 52 is rotatably connected to the first slider 42. Several connecting rods 53 are fixedly connected to one side of the first slider 42. One end of the connecting rod 53 is fixedly connected to a support frame 54. Several slots 55 are evenly opened on the inner wall of the support frame 54.

[0032] like Figure 5 , Figure 6 , Figure 8 and Figure 10 As shown, the spiral limiting assembly 6 includes a rotating plate 61 rotatably connected to the support frame 54. The rotating plate 61 has a spiral groove 62 through it, and a plurality of storage slots 63 are evenly distributed on the outer ring of the rotating plate 61.

[0033] like Figures 5-7 and Figure 10 As shown, the first measuring component 7 includes a third slider 71 slidably connected within the turntable 52. A mounting post 72 is fixedly connected to one side of the third slider 71. A rotating sleeve 73 is rotatably connected to the outer wall of the mounting post 72. A laser sensor 74 is installed at one end of the mounting post 72. The laser sensor 74 can accurately collect distance data from the surface of the eyeball and provide real-time feedback of measurement point information to achieve multi-point dynamic measurement. The laser sensor 74 is a low-power medical infrared laser sensor 74, which outputs gentle light without radiation, avoiding damage to the surface mucosa of the eyeball and sensitive tissues around the eye, thus meeting the safety requirements of eye detection. The rotating sleeve 73 is tumbledly connected to the spiral groove 62.

[0034] like Figure 6 As shown, the positioning component 8 includes several tilting frames 81 rotatably connected within the rotating plate 61. Two first springs 82 are fixedly connected to the inner wall of the tilting frame 81. The first springs 82 have a large elastic force, which can prevent the rotating plate 61 from rotating within the support frame 54 during the reset process of the first measuring component 7. The other ends of the two first springs 82 are fixedly connected to the inner wall of the storage groove 63. The tilting frame 81 is engaged with the slot 55. The depth of the storage groove 63 matches the height of the tilting frame 81, which allows the tilting frame 81 to be completely stored within the storage groove 63 when squeezed, avoiding protrusion and interference with the rotation of the rotating plate 61 within the support frame 54. At the same time, it ensures that the tilting frame 81 can be accurately extended and stably engaged with the slot 55 when the first spring 82 is reset, ensuring smooth extension and retraction of the positioning component 8 and positioning accuracy. It provides reliable structural support for the angle switching of the spiral limiting component 6. The elastic structure within the positioning component 8 is the first spring 82.

[0035] like Figure 4 , Figure 8 and Figure 9As shown, the second measuring component 9 includes a first fixed seat 91 fixedly connected to one side of the crossbar 32, and a second fixed seat 92 fixedly connected to one side of the second slider 43. A lifting plate 93 is slidably connected inside both the first fixed seat 91 and the second fixed seat 92. Two second springs 94 are fixedly connected to the inner walls of both the first fixed seat 91 and the second fixed seat 92. One end of each second spring 94 is fixedly connected to both sides of the lifting plate 93. A mounting block 95 is fixedly connected to one side of one of the lifting plates 93, and an infrared sensor 96 is mounted on one side of the mounting block 95. The infrared sensor 96 can accurately detect the distance to the bone reference plane of the lateral edge of the orbit, and identifies the echo intensity... The peak intensity locks onto the bone region, eliminating interference from soft tissues such as skin and fat, and outputs stable and reliable distance measurement data. The infrared sensor 96 is a high-precision medical reflective infrared ranging sensor, which can avoid measurement reference positioning deviation caused by soft tissue obstruction. At the same time, its low-power non-contact detection design can avoid pressure or thermal damage to the skin and subcutaneous tissue around the eye socket, ensuring the safety and comfort of the detection process. The detection references of the infrared sensor 96 and the laser sensor 74 are in the same vertical plane and remain horizontally aligned, ensuring that the distance data measured by both are based on the same spatial reference dimension, avoiding distance difference calculation deviation caused by reference misalignment.

[0036] In use, the patient places the fixing frame 1 on the corresponding position of the eyes using two connecting plates 21 and elastic bands 22. At this time, the rubber pad 12 fits against the patient's eye socket. Then, the operator fine-tunes the position of the fixing frame 1 so that its horizontal position is consistent with the horizontal position of the patient's two eyeballs. At this time, the visual sensor 33 detects the movement, and the controller 11 causes the two dual-output electric push rods 41 to drive the first slider 42 and the second slider 43 to slide within the horizontal bar 32, thereby adjusting the measurement positions of the laser sensor 74 and the infrared sensor 96. This ensures that the measurement positions of one set of laser sensors 74 and infrared sensors 96 correspond to the patient's left eyeball and the outer edge of the left eye socket, and the measurement positions of the other set of laser sensors 74 and infrared sensors 96 correspond to the patient's right eyeball and the outer edge of the right eye socket. This enables synchronous and precise alignment of the left and right eyeballs with the corresponding outer edges of the eye sockets. Compared with the shortcomings of existing technologies where manual alignment is inaccurate and inefficient, this technology can achieve automated alignment of the protrusion of both eyeballs, improving the accuracy and efficiency of the measurement.

[0037] After the two sets of laser sensors 74 and infrared sensors 96 are aligned, the controller 11 causes the motor 51 to drive the turntable 52 to rotate within the first slider 42, which in turn drives the mounting post 72, rotating sleeve 73, and laser sensor 74 to rotate synchronously in the forward direction. During the forward rotation of the mounting post 72, rotating sleeve 73, and laser sensor 74, the rotating sleeve 73 rolls within the spiral groove 62 of the rotating plate 61 due to its limiting function. At the same time, the third slider 71 slides within the turntable 52, causing the laser sensor 74 to rotate in a spiral motion. This allows for the synchronous acquisition of multi-point distance data. Compared with the single-point measurement and the shortcomings of existing technologies, such as incomplete data and susceptibility to human operation, this method can obtain more comprehensive eyeball protrusion data and improve the accuracy of the measurement results.

[0038] Meanwhile, due to the dead angle in the limiting path of the spiral groove 62, the controller 11 causes the motor 51 to drive the laser sensor 74 to rotate in the opposite direction, resetting the laser sensor 74 to its initial position. Subsequently, the motor 51 drives the mounting post 72, the rotating sleeve 73, and the laser sensor 74 to rotate in the opposite direction by ninety degrees again. This causes the mounting post 72 and the rotating sleeve 73 to push the rotating plate 61 to rotate ninety degrees within the support frame 54. During the rotation of the rotating plate 61, it drives several tilting frames 81 and the first spring 82 to rotate synchronously, causing the tilting frames 81 to rotate and gradually compress the first spring 82 until the tilting frames 81 enter the receiving groove 63. After the first measuring component 7 rotates in the opposite direction by ninety degrees again, the first spring 82 resets, allowing the tilting frames 81 to re-enter the slot. 55 is engaged, and then the controller 11 causes the motor 51 to drive the laser sensor 74 to rotate forward again, allowing the laser sensor 74 to perform multi-point distance measurements again. Then, the controller 11 causes the motor 51 to drive the laser sensor 74 to rotate in the opposite direction, allowing the laser sensor 74 to return to its initial position. This operation is repeated four times, enabling 360-degree path adjustment. This changes the path of the spiral groove 62 sequentially, allowing the detection position of the laser sensor 74 to cover the surface of the eyeball from multiple directions. This achieves multi-point measurement of eyeball protrusion and obtains complete data. Compared with the shortcomings of existing technologies, such as numerous blind spots and insufficient data integrity, this reduces measurement dead zones and further improves the comprehensiveness and accuracy of eyeball protrusion measurement data.

[0039] To address the technical challenge of adapting ocular protrusion measurement devices to varying orbital lateral margin heights in different patients, such as... Figure 2 , Figure 3 , Figure 8 and Figure 10 As shown, the following preferred technical solutions are provided: like Figure 8 and Figure 10As shown, the pushing assembly 10 includes an L-shaped push rod 101 fixedly connected to one side of the rotating plate 61, and a roller 102 is rotatably connected to one end of the L-shaped push rod 101.

[0040] like Figure 8 and Figure 10 As shown, the linkage component 20 includes a first fixed rod 201 and a second fixed rod 202 respectively fixedly connected to one side of the two lifting plates 93. A sliding rod 203 is slidably connected to the outer wall of the second fixed rod 202. Through the sliding connection between the second fixed rod 202 and the sliding rod 203, the positional deviation caused by the movement of the second slider 43 driven by the alignment component 4 can be adapted and adjusted, ensuring that the power of the pushing component 10 is stably transmitted to the linkage component 20. A lifting frame 204 is fixedly connected to one end of the first fixed rod 201 and the sliding rod 203. The roller 102 is in contact with the lifting frame 204. When the L-shaped push rod 101 drives the roller 102 to push the lifting frame 204 up and down, the lifting frame 204 will not interfere with the movement path of the laser sensor 74, avoiding mechanical collision between the two and causing damage to the components, and at the same time avoiding affecting the measurement.

[0041] By controlling the controller 11, the motor 51 drives the laser sensor 74 to rotate 90 degrees in the opposite direction. After the rotating plate 61 rotates 90 degrees within the support frame 54, it drives the L-shaped push rod 101 and the roller 102 to rotate 90 degrees as well. This causes the L-shaped push rod 101 to drive the roller 102 to push the lower inner wall of the lifting frame 204, making the lifting frame 204 move downward as a whole. This also causes the first fixed rod 201, the second fixed rod 202, the sliding rod 203, the lifting plate 93, the mounting block 95, and the infrared sensor 96 to move downward synchronously, and simultaneously stretch the second spring 9 at the top of the lifting plate 93. 4. The second spring 94 at the bottom of the compression lifting plate 93, when the controller 11 causes the motor 51 to drive the laser sensor 74 to rotate in the opposite direction to an angle of 270 degrees, can cause the L-shaped push rod 101 to drive the roller 102 to push the lifting frame 204 upward, and drive the infrared sensor 96 to move upward synchronously. It can complete the dynamic measurement of the second measuring component 9 by lifting up and down while the laser sensor 74 and the rotating plate 61 rotate in opposite directions, forming a dynamic adaptation measurement for different height positions of the outer edge of the orbit, thereby adapting to different patients and obtaining more accurate measurement data.

[0042] Then, through the controller 11, the minimum value measured by the laser sensor 74 is obtained, which is the distance between the eyeball protrusion position and the laser sensor 74. The peak point with the largest echo intensity measured by the infrared sensor 96 is the distance between the outer edge of the orbit and the infrared sensor 96. The difference between the distance between the eyeball protrusion position and the laser sensor 74 and the distance between the outer edge of the orbit and the infrared sensor 96 is the measured value of the eyeball protrusion.
