Description

Technical Field

[0001] This utility model relates to the field of ophthalmic medical testing equipment technology, and in particular to a testing device for the combined efficacy of Toric lens implantation. Background Technology

[0002] Toric lens implantation is an important surgical procedure for correcting astigmatism and is widely used in ophthalmological clinical treatment. However, accurately assessing the efficacy of toric lens implantation is crucial for patients' visual recovery and subsequent treatment decisions.

[0003] Currently, existing detection methods and devices have certain limitations: on the one hand, although devices such as corneal topography instruments can measure the power and axis of corneal astigmatism, they cannot comprehensively assess the interaction between the lens and other structures in the eye, as well as the minute changes in the lens position. On the other hand, optical biometers such as IOL-master mainly focus on measuring parameters such as lens power before surgery, and are not accurate or real-time enough for dynamic detection of postoperative efficacy.

[0004] On the other hand, existing testing devices are often single-function and cannot simultaneously detect multiple factors that affect the efficacy of Toric lens implantation. This forces doctors to use multiple devices for multiple tests, which not only increases testing time and cost, but may also affect the accurate judgment of efficacy due to errors in the test results of different devices. Furthermore, they are inconvenient to adjust and reduce the scope of application of the devices.

[0005] Therefore, developing a device that can accurately, comprehensively, and in real-time detect the efficacy of combined Toric lens implantation has significant clinical implications and application value. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings mentioned above by proposing a detection device that combines the efficacy of Toric lens implantation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A detection device for the efficacy of combined Toric lens implantation includes a base, a mounting seat slidably disposed on the top of the base, and a detection device body for detecting the efficacy of combined Toric lens implantation fixedly connected to the top of the mounting seat. The detection device body is provided with a processor, an optical detection module, and a data processing and analysis module. A touch screen is provided on one side of the detection device body. The optical detection module, the data processing and analysis module, and the touch screen are all electrically connected to the processor. An adjustment and fixing mechanism is provided between the mounting seat and the base. An adjustable support mechanism for supporting the patient's head is provided on the base.

[0009] As a preferred embodiment of this invention, the optical detection module includes a corneal topography unit, an optical biometry unit, and an optical coherence tomography (OCT) scanner unit, all of which are electrically connected to the processor.

[0010] In a preferred embodiment of this utility model, the top of the base is provided with a sliding groove. The adjustment and fixing mechanism includes guide rods fixedly connected to the inner walls on both sides of the sliding groove, and a slide block slidably sleeved between the sliding groove and the guide rods. The mounting base is fixedly connected to the top of the slide block. Two compression springs are fixedly connected to the inner wall of the top of the mounting base. The lower ends of the two compression springs are fixedly connected to the same lifting plate. The bottom of the lifting plate is fixedly connected to two brake pads, both of which movably abut against the outside of the guide rod. The top of the lifting plate is fixedly connected to a pull rod, and the top of the pull rod is fixedly connected to a mounting bracket. The front and rear sides of the mounting bracket are provided with elongated holes. The same round rod is slidably sleeved in the two elongated holes. A pressure rod is fixedly sleeved on the outside of the round rod. The top of the mounting base is fixedly connected to two vertical plates, and the pressure rod is rotatably connected between the two vertical plates.

[0011] As a preferred embodiment of this utility model, the front and rear ends of the round rod are fixedly connected to limiting plates, and the two limiting plates are respectively movably abutting against the front and rear sides of the mounting frame.

[0012] As a preferred embodiment of this invention, the lifting plate and the brake pad are fixedly connected by the same connecting rod.

[0013] As a preferred embodiment of this utility model, the top of the mounting base is provided with a through hole, the pull rod is slidably sleeved in the through hole, and a rubber sleeve is fixedly sleeved on the outside of the pressure rod.

[0014] As a preferred embodiment of this utility model, the adjustable support mechanism includes a cylinder and two columns fixedly connected to the top of the base. A common baffle is fixedly connected between the two columns. An adjusting rod is slidably sleeved inside the cylinder. Several slots are provided on the front side of the adjusting rod. A screw is threadedly connected to the front side of the cylinder. The screw is movably engaged in the corresponding slot. A support plate is fixedly connected to the top of the adjusting rod.

[0015] As a preferred embodiment of this utility model, the outer side of the column is provided with a sliding sleeve, and the support plate is fixedly connected between the two sliding sleeves.

[0016] In this invention, a detection device for the combined efficacy of Toric lens implantation is described. The patient sits in front of the device. Depending on the size of the patient's head, the screws are loosened to disengage from the slots, thus not fixing the support plate. The support plate is then pulled up and down to adjust the distance between the support plate and the retaining band. After adjustment, the screws are tightened to engage with the corresponding slots, thus fixing the support plate. Then, according to the detection requirements, the pressure rod is pressed down. The pressure rod causes the round rod to move upwards, sliding within two elongated holes and causing the mounting bracket and pull rod to move upwards. The pull rod causes the lifting plate and two brake pads to move upwards without contacting the top of the guide rod, thus not fixing the slide and mounting base. At this point, the detection distance between the detection device body and the support plate can be adjusted. After adjustment, the pressure rod is released. Under the elastic force of the compression spring, the two brake pads move downwards and firmly abut against the outside of the guide rod, thus fixing the mounting base.

[0017] In this invention, a detection device for the efficacy of Toric lens implantation is described. The doctor initiates the detection program via a touchscreen. The corneal topography unit in the optical detection module first scans the cornea to obtain information on reflected light from the corneal surface and transmits it to the data processing and analysis module. The optical biometry unit measures parameters such as axial length and corneal curvature, and the measurement data is also transmitted to the data processing and analysis module. The optical coherence tomography unit performs tomographic scanning of the eye tissue, generating high-resolution image data, which is then sent to the data processing and analysis module. The data processing and analysis module integrates and analyzes the above data to evaluate the efficacy of Toric lens implantation. The touchscreen displays the analysis results in an intuitive manner for the doctor to view and judge.

[0018] This utility model has a reasonable structural design and integrates multiple detection functions. It can simultaneously detect multiple aspects such as the cornea, axial length, lens and surrounding tissues, comprehensively evaluate the efficacy of Toric lens implantation, overcome the shortcomings of existing devices with single functions, and adjust the distance between the tray and the guard strap as well as the distance between the detection device and the patient's eye, thereby improving the practicality of the device and ensuring the accuracy of the detection.

[0024] 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.

[0025] Reference Figures 1-4 A detection device for the efficacy of combined Toric lens implantation includes a base 1, a mounting seat 2 slidably disposed on the top of the base 1, and a detection device body 3 for detecting the efficacy of combined Toric lens implantation fixedly connected to the top of the mounting seat 2. The detection device body 3 is provided with a processor, an optical detection module, and a data processing and analysis module. A touch screen 6 is provided on one side of the detection device body 3. The optical detection module, the data processing and analysis module, and the touch screen 6 are all electrically connected to the processor. An adjustment and fixing mechanism 4 is provided between the mounting seat 2 and the base 1. An adjustable support mechanism 5 for supporting the patient's head is provided on the base 1. The optical detection module includes a corneal topography unit, an optical biometry unit, and an optical coherence tomography (OCT) scanner unit. The corneal topography unit, the optical biometry unit, and the OCT scanner unit are all electrically connected to the processor.

[0026] Using the above scheme: The doctor starts the detection program through the touch screen 6. The corneal topography unit in the optical detection module first scans the cornea to obtain the information of reflected light on the corneal surface and transmits it to the data processing and analysis module. The optical biometry unit measures parameters such as axial length and corneal curvature, and the measurement data is also transmitted to the data processing and analysis module. The optical coherence tomography unit performs tomographic scanning of the eye tissue, generates high-resolution image data, and sends it to the data processing and analysis module. The data processing and analysis module integrates and analyzes the above data to evaluate the efficacy of Toric lens implantation. The touch screen 6 displays the analysis results in an intuitive way for the doctor to view and judge.

[0027] Furthermore, refer to Figures 1-3 The base 1 has a groove 401 on its top. The adjusting and fixing mechanism 4 includes guide rods 402 fixedly connected to the inner walls of both sides of the groove 401, and a slide block 403 slidably sleeved between the groove 401 and the guide rods 402. The mounting base 2 is fixedly connected to the top of the slide block 403. Two compression springs 414 are fixedly connected to the inner wall of the top of the mounting base 2. The lower ends of the two compression springs 414 are fixedly connected to the same lifting plate 407. The bottom of the lifting plate 407 is fixedly connected to two brake pads 404. Each brake pad 404 is movably abutted against the outside of the guide rod 402. The top of the lifting plate 407 is fixedly connected to a pull rod 405. The top of the pull rod 405 is fixedly connected to a mounting bracket 408. The front and rear sides of the mounting bracket 408 are provided with elongated holes 409. The same round rod 411 is slidably sleeved in the two elongated holes 409. The outside of the round rod 411 is fixedly sleeved with a pressure rod 413. The top of the mounting base 2 is fixedly connected to two vertical plates 412. The pressure rod 413 is rotatably connected between the two vertical plates 412.

[0028] Using the above scheme: According to the needs of the test, press down the pressure rod 413. The pressure rod 413 drives the round rod 411 to move upward. The round rod 411 slides in the two elongated holes 409 and drives the mounting bracket 408 and the pull rod 405 to move upward. The pull rod 405 drives the lifting plate 407 and the two brake pads 404 to move upward without contacting the top of the guide rod 402, so as not to fix the slide 403 and the mounting seat 2. At this time, the detection distance between the detection device body 3 and the support plate 57 can be adjusted. After adjustment, release the pressure rod 413. At this time, under the elastic force of the compression spring 414, the two brake pads 404 move downward and firmly abut against the outside of the guide rod 402, so as to fix the mounting seat 2.

[0029] Furthermore, the front and rear ends of the round rod 411 are fixedly connected to the limiting plate 410. The two limiting plates 410 are respectively movably abutted against the front and rear sides of the mounting bracket 408, which can limit the round rod 411 and prevent the round rod 411 from dislodging from the elongated hole 409.

[0030] Furthermore, the lifting plate 407 and the brake pad 404 are fixedly connected by the same connecting rod 406, which makes it convenient for the two brake pads 404 to be fixed to the bottom of the two lifting plates 407.

[0031] Furthermore, the top of the mounting base 2 is provided with a through hole, the pull rod 405 is slidably sleeved in the through hole, and the outer side of the pressure rod 413 is fixedly sleeved with a rubber sleeve, which facilitates the guidance of the pull rod 405 and allows personnel to comfortably press down the pressure rod 413.

[0032] Furthermore, refer to Figure 1 and Figure 2 The adjustable support mechanism 5 includes a cylindrical body 52 fixedly connected to the top of the base 1 and two columns 51. The two columns 51 are fixedly connected to the same baffle 58. An adjusting rod 54 is slidably sleeved inside the cylindrical body 52. ​​Several slots 56 are opened on the front side of the adjusting rod 54. A screw 53 is threadedly connected to the front side of the cylindrical body 52. ​​The screw 53 is movably engaged in the corresponding slot 56. A support plate 57 is fixedly connected to the top of the adjusting rod 54.

[0033] Using the above method: Based on the size of the patient's head, loosen screw 53 so that screw 53 disengages from slot 56, thus not fixing the support plate 57. At this time, pull the support plate 57 up and down to adjust the distance between the support plate 57 and the retaining strap 58. After adjustment, tighten screw 53 so that screw 53 is inserted into the corresponding slot 56, thus fixing the support plate 57.

[0034] Furthermore, the outer side of the column 51 is provided with a sliding sleeve 55, and the support plate 57 is fixedly connected between the two sliding sleeves 55, which facilitates the guidance of the support plate 57 and makes its movement more stable and smooth.

[0035] In this invention, during use, the patient sits in front of the testing device. Depending on the size of the patient's head, the screw 53 is loosened, disengaging from the slot 56, thus not fixing the support plate 57. At this point, the support plate 57 can be adjusted by pulling it up and down to change the distance between it and the retaining band 58. After adjustment, the screw 53 is tightened, engaging the corresponding slot 56, thus fixing the support plate 57. Then, according to the testing requirements, the pressure rod 413 is pressed down, causing the round rod 411 to move upwards. The round rod 411 moves upwards between the two... The slide is slidable within the elongated hole 409, which drives the mounting bracket 408 and the pull rod 405 to move upward. The pull rod 405 drives the lifting plate 407 and the two brake pads 404 to move upward without contacting the top of the guide rod 402, thus not fixing the slide 403 and the mounting base 2. At this time, the detection distance between the detection device body 3 and the support plate 57 can be adjusted. After adjustment, the pressure rod 413 is released. At this time, under the elastic force of the compression spring 414, the two brake pads 404 move downward and firmly abut against the outside of the guide rod 402, thus fixing the mounting base 2.

[0036] The doctor initiates the testing process via touchscreen 6. The corneal topography unit in the optical detection module first scans the cornea to obtain information on reflected light from the corneal surface and transmits it to the data processing and analysis module. The optical biometry unit measures parameters such as axial length and corneal curvature, and the measurement data is also transmitted to the data processing and analysis module. The optical coherence tomography unit performs tomographic scanning of the eye tissue, generates high-resolution image data, and sends it to the data processing and analysis module. The data processing and analysis module integrates and analyzes the above data to evaluate the efficacy of Toric lens implantation. Touchscreen 6 displays the analysis results in an intuitive way for the doctor to view and make a judgment.
