Description

Technical Field

[0001] The present application relates to the technical field of ophthalmic examination equipment, and in particular to a detachable combined slit lamp microscope system. Background Art

[0002] In the clinical diagnosis of ophthalmic diseases, slit lamp microscopes are an indispensable core tool. Through the combination of high-brightness slit light source and high-resolution optical system, the microscopic structure of ocular tissues (such as cornea, anterior chamber, lens, etc.) can be clearly observed, providing a key basis for the accurate diagnosis of diseases such as keratitis, glaucoma, and cataracts. However, traditional slit lamp microscopes generally have the following technical defects:

[0003] Most of the existing mainstream equipment is a fixed desktop structure, relying on a stable power supply and a dedicated operating table, and is bulky (usually covering an area of ​​0.5m 3 The weight of the device is more than 20 kg, which makes it difficult to quickly deploy in non-fixed scenarios such as medical tours in remote mountainous areas, emergency rescue in emergencies, and home visits. This results in the inability of ophthalmic professional examination services to cover resource-poor areas in a timely manner, delaying the early diagnosis and treatment of patients.

[0004] Although the existing portable slit lamps on the market have achieved lightweight through simplified structure (such as handheld design), they have sacrificed optical performance (such as numerical aperture <0.3, fixed magnification), resulting in insufficient imaging resolution. They are only suitable for preliminary screening and cannot meet the needs of fine diagnosis such as lens opacity grading and corneal endothelial cell counting. Medical institutions are forced to purchase both desktop and portable devices, which significantly increases costs.

[0005] Traditional portable devices lack head fixation devices, and patients are required to actively cooperate and remain still during the examination, which can easily lead to blurred images due to head shaking. At the same time, doctors need to hold the device throughout the process and manually adjust the focus, which can easily cause fatigue after long-term operation, affecting diagnostic efficiency and accuracy.

[0006] Existing equipment has single functions and cannot be flexibly combined according to scenario requirements (such as temporarily adding a precision adjustment platform or bracket), which limits the adaptability of the equipment in complex medical environments. Summary of the invention

[0007] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a detachable combined slit lamp microscope system. Through a modular split design and the linkage between a detachable bracket assembly and a three-dimensional mobile platform, the present application solves the problems of poor scene adaptability of traditional equipment, the inability to balance portability and performance, and low operational stability, thereby achieving the unity of professional-level diagnostic capabilities and flexible applications in all scenarios.

[0018] According to some embodiments of the present application, the three-dimensional mobile platform includes a motion slide, an operating rod and a base platform; wherein the operating rod and the motion slide are both integrated and installed above the base platform;

[0019] The motion slide, operating rod and base platform work together to achieve high-precision spatial positioning of the portable slit lamp group and stable linkage of the bracket components, ensuring accurate adjustment of the inspection position, focal length and angle.

[0020] According to some embodiments of the present application, the moving slide is built with a groove interface that is adapted to the shape of the locking and limiting structure of the supporting platform on the portable slit lamp assembly, and the two cooperate to fix the portable slit lamp assembly;

[0048] The following describes a detachable combined slit lamp microscope system according to an embodiment of the present application with reference to the accompanying drawings.

[0049] like Figure 1-Figure 7 The detachable combined slit lamp microscope system according to the embodiment of the present application comprises: a portable slit lamp assembly 1, a bracket assembly 2 and a three-dimensional mobile platform 3, wherein the portable slit lamp assembly 1, the bracket assembly 2 and the three-dimensional mobile platform 3 are connected in a modular manner through a detachable standardized interface such as a thread and a locking device, and support independent disassembly and multi-mode combined use;

[0050] The portable slit lamp assembly 1 and the bracket assembly 2 are both located above the three-dimensional mobile platform 3. The three-dimensional mobile platform 3 provides multi-axis precision adjustment support for the portable slit lamp assembly 1 through a detachable connection, and simultaneously fixes the bracket assembly 2, so as to achieve precise control of the inspection position, height and focal length, and improve operational stability and detection accuracy.

[0051] The portable slit lamp assembly 1 is a core component with built-in key optical and electronic components; the bracket assembly 2 is responsible for supporting the subject's head to reduce the pressure on the subject during the examination and increase stability; the three-dimensional mobile platform 3 is responsible for carrying and moving the portable slit lamp assembly 1 and the mounting bracket assembly 2 to adjust the observation height, position and focus.

[0052] The portable slit lamp assembly 1 is detachably connected to the groove of the three-dimensional mobile platform 3 through a locking and limiting structure, and the telescopic rod 203 of the bracket assembly 2 is detachably fixed to the base platform 303 of the three-dimensional mobile platform 3 through a threaded interface. The combination of the three constitutes a modular slit lamp microscope system that can adapt to handheld, bracket-fixed and high-precision adjustment modes.

[0053] The portable slit lamp set 1 includes a digital microscope camera system 101 and a slit system 102, and the digital microscope camera system 101 and the slit system 102 work together to achieve high-resolution imaging of eye tissue and multi-scene adaptive lighting through the coaxial precise matching of the achromatic lens group and the high-brightness adjustable LED light source, thereby ensuring the clarity of the slit lamp examination and the reliability of the diagnosis;

[0054] The core function of the digital microscope camera system 101 is that the achromatic lens group eliminates chromatic aberration and improves image sharpness; and it can switch between multiple levels of magnification such as 5×-25× and continuous focusing accuracy ≤0.1mm to meet the observation requirements of different lesions.

[0055] The slit system 102 is a high-brightness LED with an adjustable 1000-5000 lux to adapt to strong light / dark light environments; its slit width adjustment of 0.1-10mm and angle adjustment of ±15° optimize the lighting area and contrast.

[0056] The digital microscope camera system 101 and the slit system 102 work together to ensure that the light source is accurately projected to the target area of ​​the eye after passing through the achromatic lens group through the coaxial optical path design, thereby avoiding image blur caused by optical path deviation; and the linkage adjustment of the light source brightness, slit width and magnification allows doctors to quickly adapt to the inspection needs of different parts such as the cornea, anterior chamber, and lens.

[0057] The portable slit lamp set 1 also includes a housing 104, and the digital microscope camera system 101 and the slit system 102 are integrated and installed in the housing 104. The housing 104 is made of lightweight and high-strength material, and the surface is processed by micro-arc oxidation and frosting to form a non-slip and wear-resistant layer.

[0058] The digital microscope camera system 101 is integrated in the front end of the housing 104, and includes an achromatic lens group, a high-precision focusing mechanism and a multi-level magnification switching mechanism. The focusing mechanism controls the focal length through a roller or a knob, and the magnification switching mechanism supports at least three levels of magnification adjustment.

[0059] At the same time, the slit system 102 is embedded in the middle of the housing 104, and includes a high-brightness LED module, a slit width adjustment wheel and a brightness adjustment knob. The light emission direction of the LED module is aligned with the optical axis of the optical system.

[0060] A support platform 103 is installed at the bottom of the housing 104. Figure 2-Figure 3 As shown, the surface of the support platform 103 is provided with an arc guide rail and a locking limit structure, wherein the arc guide rail is an arc-shaped sliding track, and the arc guide rail is used to adjust the angle between the light source module and the optical system;

[0061] The arc-shaped sliding track design allows the slit system 102 to be adjusted relative to the optical axis of the digital microscope camera system 101, such as within a range of ±15°; by changing the incident angle of light, surface reflection or stray light interference is reduced, and the clarity of the lesion area is improved; for example, corneal scratches are observed through side lighting;

[0062] like Figure 2 As shown, the locking and limiting structure is adapted to the groove interface of the three-dimensional moving platform 3 of the three-dimensional motion platform assembly to achieve detachable fixation.

[0063] The support assembly 2 includes a forehead support 201 and a chin support 202, and two telescopic rods 203 that are symmetrically arranged, and a desktop clamp 204 is arranged below the telescopic rods 203;

[0064] In this solution, the forehead support 201, the mandibular support 202, the telescopic rod 203 and the desktop clamp 204 work together to stabilize the patient's head position and adapt to different examination scenarios through detachable connection and height adjustment functions, such as desktop fixation or linkage with the three-dimensional mobile platform 3, to improve the examination comfort and operation accuracy;

[0065] The forehead support 201 is designed with an arc-shaped surface to fit the contour of the human forehead; the chin support 202 is arranged parallel to the forehead support 201, wherein the arc-shaped surfaces of the forehead support 201 and the chin support 202 are embedded with a silicone cushion layer with a thickness of ≥3mm, and a ventilation hole is provided on the surface to improve the comfort of the patient;

[0066] The length adjustment range of the telescopic rod 203 is 30-60 cm, which is suitable for the difference in sitting height between adults and children.

[0067] At the same time, the telescopic rod 203 has slots at both ends, and the forehead support 201 and the mandibular support 202 have buckles knitted at both ends. The buckles are used in conjunction with the slots. When the buckles on the mandibular support 202 and the mandibular support 202 are respectively inserted into the corresponding insertion slots on the telescopic rod 203, the forehead support 201 and the mandibular support 202 can be movably mounted on the surface of the telescopic rod 203.

[0068] In this way, the telescopic rod 203 is detachably connected to the forehead support 201 and the chin support 202 respectively; the telescopic rod 203 is a telescopic rod, and a locking knob is provided at the bottom of the surface of the telescopic rod 203. The length of the telescopic rod 203 is adjustable and fixed by the locking knob;

[0069] The desktop clamp 204 is used in conjunction with the telescopic rod 203, and the desktop clamp 204 can be installed on any platform to fix the bracket assembly 2 as a whole. The bottom of the telescopic rod 203 and the inner cavity of the end of the desktop clamp 204 are both provided with threads, so that when the telescopic rod 203 and the desktop clamp 204 are connected, it is only necessary to screw the telescopic rod 203 into the desktop clamp 204.

[0070] like Figure 4 As shown, at the same time, a non-slip pad and a locking wrench are provided at the end of the desktop clamp 204, the connection between the locking wrench and the desktop clamp 204 is a threaded connection, and the non-slip pad is located above the locking wrench, and the two are used together to adapt to desktops of different thicknesses;

[0071] In this solution, the forehead support 201 and the chin support 202 play the role of head stabilization. The two fit the patient's face through the curved surface and the soft cushion layer, limiting the shaking of the head and reducing muscle tension during the examination.

[0072] In this solution, the length of the telescopic rod 203 is adjusted by 30-60 cm to accommodate the height differences between adults and children, ensuring a comfortable sitting posture;

[0073] In this solution, the desktop clamp 204 plays a role in adapting to multiple scenarios. The desktop clamp 204 is connected to the telescopic rod 203 through a threaded interface and can be quickly fixed on a desktop or a three-dimensional platform to meet the needs of multiple scenarios from simple free clinics to high-precision examinations.

[0074] The design of the quick-release card slot and buckle, as well as the double-thread design on the telescopic rod 203 and the desktop clamp 204, enables quick assembly and disassembly of components, reduces equipment deployment time, and improves doctor's operating efficiency.

[0075] The three-dimensional mobile platform 3 includes a motion slide 301, an operating rod 302 and a base platform 303; wherein the operating rod 302 and the motion slide 301 are both integrated and installed above the base platform 303;

[0076] The motion slide 301, the operating rod 302 and the base platform 303 cooperate with each other to realize the high-precision spatial positioning of the portable slit lamp assembly 1 and the stable linkage of the bracket assembly 2, ensuring the precise adjustment of the inspection position, focal length and angle;

[0077] The base platform 303 provides a stable base and is connected to the telescopic rod 203 of the bracket assembly 2 through a threaded hole to ensure the overall rigidity of the bracket assembly 2 when linked with the host three-dimensional mobile platform 3 to avoid deviation due to external force during operation.

[0078] like Figure 5As shown, the moving slide 301 has a built-in groove interface that matches the locking and limiting structure shape of the supporting platform 103 on the portable slit lamp set 1, and the two cooperate to fix the portable slit lamp set 1;

[0079] like Figure 5 As shown, the base platform 303 carries the motion slide 301, and a threaded hole is provided on the base of the motion slide 301 to connect the telescopic rod 203 of the bracket assembly 2;

[0080] like Figure 6 As shown, the operating rod 302 is integrated on one side of the base platform 303 and is electrically connected to the motion slide 301 to control the front-back, left-right, and up-down three-axis movement of the three-dimensional motion platform motion slide 301 .

[0081] The three-axis movement accuracy of the operating rod 302 is ≤0.1mm, the vertical adjustment range is ≥15cm, and the movement path is marked with scales to achieve position reproduction;

[0082] The combination of the motion slide 301, the operating rod 302 and the base platform 303 solves the problems of positioning ambiguity and operation jitter caused by the simplified structure of traditional portable devices. While ensuring portability, it achieves inspection accuracy and scene adaptability comparable to professional desktop equipment.

[0083] The threaded hole of the base platform 303 is a double-thread design, which is respectively adapted to the bottom thread of the telescopic rod 203 and the independent desktop fixing requirements.
