Description

Technical Field

[0001] This invention belongs to the field of eye treatment and diagnostic equipment technology, specifically relating to a remotely controlled slit lamp and its light source structure. Background Technology

[0002] The slit lamp, also known as a slit-lamp microscope, is an important ophthalmic examination instrument. The slit lamp's illumination system uses the Cole illumination method; the light source passes through a series of optical components to form a bright, cross-sectional image on the eye. Doctors then examine the eye using a binocular stereomicroscope, and the magnification can be adjusted.

[0003] Slit lamps typically use slit modulators to adjust the slit width, thereby changing the fiber width. Existing slit modulators are always positioned in front of the light source, emitting only light from the slit. When diffused light is needed, an additional light source is often required, causing inconvenience in production and maintenance. Therefore, it is necessary to design a new light source structure for slit lamps. Summary of the Invention

[0004] To address the aforementioned problems in existing technologies, this solution provides a remotely controlled slit lamp and its light source structure.

The first stop block is horizontally slidably set on the front side of the stop block frame and can move up and down with the stop block frame. The second stop block is provided with a long strip of vertical first light source channel. The second stop is rotatably set at the center of the stop frame, and a long strip-shaped second light source channel is provided on the second stop. When the second light source channel is parallel to the first light source channel, the light becomes a flat slit light after passing through the two light sources. When the second light source channel intersects with the first light source channel, the light becomes a point light after passing through the two light sources. When the second light source channel is parallel to the first light source channel, sliding the second stop horizontally can change the width of the flat slit light.

[0006] Optionally: The upper and lower parts of the first stop are slidably connected to a track rod, and the two ends of the track rod are fixedly connected to the stop frame seat, so that the first stop can slide horizontally along the track rod.

[0009] Optional: The light source structure also includes a structural housing, on which a lifting screw is installed. The lifting screw is driven by a motor and threadedly connected to the stop block frame to control the lifting and moving of the stop block frame.

[0010] A light source structure for a remotely controlled slit lamp includes a housing and a head support frame, a displacement mechanism, a support assembly, an image acquisition unit, and a light source structure installed inside the housing. The displacement mechanism includes a transverse module and a longitudinal module; the transverse module is mounted on the longitudinal module. The support assembly is mounted on the displacement mechanism and its horizontal movement is controlled by the displacement mechanism. The support assembly includes multiple independently rotatable support arms. The light source structure and the image acquisition device are respectively mounted on different support arms, so that the light source structure can illuminate from different directions and the image acquisition device can acquire images from different directions. The head support frame is mounted at the front of the support assembly and is used for supporting and positioning the human head. The electrical components of the head support frame, displacement mechanism, support assembly, image acquisition device, and light source structure are connected to the controller, which communicates with a remote server to remotely control the slit lamp.

[0011] Optionally: The head support frame includes a head bracket, on which a chin support for chin positioning and a forehead support for forehead positioning are provided; a telescopic electric cylinder is connected to the bottom of the head bracket, and guide rods are provided on opposite sides of the telescopic electric cylinder, the upper end of the guide rod is fixed to the head bracket, and the lower end is slidably connected to the guide sleeve, which is fixed to the bottom wall of the housing.

[0012] Optionally: The support arm includes a lateral fixed arm and a lateral sliding arm; the lateral sliding arm is slidably connected to the lateral fixed arm, one end of the lateral sliding arm is fixed with a lateral movement motor, and the lateral movement screw connected to the output shaft of the lateral movement motor is threadedly connected to the lateral fixed arm.

[0015] The beneficial effects of this invention are as follows: This solution uses a structure where a first and a second stop block cooperate to form a slit, thereby facilitating the formation of a flat light beam to aid in eye examination. Simultaneously, the width of the light beam is altered by the relative translation of the first and second stop blocks, and the switching between flat slit light and point light is achieved by changing the relative angle. Furthermore, the main body of the light source can be used as a diffuse light source by raising and lowering the two stop blocks, achieving multi-functionality and providing convenience for production and maintenance.

Detailed Implementation

[0019] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0020] Example 1 like Figures 1 to 7 As shown, this embodiment designs a remotely controlled slit lamp light source structure 6, including a structural shell 61, a light source body 62, and a slit assembly.

[0021] The outer shell 61 can be a hollow plastic shell, and components such as the light source body 62, the block frame 69, the first block 63, and the second block 64 can all be installed inside the outer shell 61.

[0022] The light source body 62 is installed on the top rear side of the structural housing 61. The light source body 62 can use a halogen lamp or an LED lamp as the light source and is equipped with corresponding lenses and reflectors for focusing and adjusting the direction of light.

[0023] The rift assembly is installed inside the structural housing 61 and located in front of the light source body 62. The rift assembly includes components such as a block frame 69, a first block 63, and a second block 64.

[0024] The stop block frame 69 adopts a square frame structure with a through hole in the middle. The stop block frame 69 can move back and forth between the diffuse irradiation station and the slit irradiation station. The slit irradiation station is located directly in front of the light source body 62, and the diffuse irradiation station is located directly below the slit irradiation station. A lifting screw 68 is threaded to the left and right sides of the structural shell 61, and the lifting screw 68 is driven by a motor to control the lifting and moving of the stop block frame 69.

[0025] When the motor rotates in the forward direction, the lifting screw 68 controls the stop frame 69 to descend, thereby moving the stop frame 69 from the slit irradiation position to the diffuse irradiation position, and moving the stop frame 69 away from the front of the light source body 62, so that the light source body 62 can illuminate the glasses with diffuse light for inspection. When the motor rotates in the reverse direction, the lifting screw 68 controls the stop frame 69 to rise, thereby moving the stop frame 69 from the diffuse irradiation position to the slit irradiation position, and moving the stop frame 69 directly in front of the light source body 62, so that the light source body 62 can illuminate the glasses with slit light for inspection.

[0026] The first stop block 63 has a square structure and is horizontally slidable on the front side of the stop block frame 69, and can move up and down with the stop block frame 69. The second stop block 64 is provided with a long, vertical first light source channel 631. The top surface of the first stop block 63 is provided with strip-shaped teeth. An adjusting motor 66 is provided on the top of the stop block frame 69, and the gear connected to the output shaft of the adjusting motor 66 meshes with the strip-shaped teeth. The upper and lower parts of the first stop block 63 are slidably connected to the track rods 65, and the two ends of the track rods 65 are fixedly connected to the stop block frame 69. The first stop block 63 can slide horizontally along the track rods 65.

[0027] The second stop 64 is disc-shaped and rotatably positioned at the center of the stop frame 69. An elongated second light source channel 641 is provided on the second stop 64. When the second light source channel 641 is parallel to the first light source channel 631, the light rays, after passing through both light sources, become flat, slit-like rays. When the second light source channel 641 intersects the first light source channel 631, the light rays, after passing through both light sources, become point-like rays. The outer periphery of the second stop 64 is provided with annular teeth. A rotary motor 67 is mounted on the stop frame 69, and a gear connected to the output shaft of the rotary motor 67 meshes with the annular teeth. When the rotary motor 67 rotates, it drives the second stop 64 to rotate, thereby causing the second light source channel 641 to rotate.

[0028] When the second light source channel 641 and the first light source channel 631 are parallel to each other, and when the adjusting motor 66 rotates in the forward or reverse direction, it can control the first stop 63 to move horizontally, thereby adjusting the overlap between the first light source channel 631 and the second light source channel 641, and thus adjusting the width of the light.

[0029] The above structure forms a slit through the cooperation of the first block 63 and the second block 64, which facilitates the formation of a flat light beam to aid in eye examination. At the same time, the width of the light beam can be changed by the relative translation of the first block 63 and the second block 64, and the switching between flat slit light beam and point light beam can be achieved by changing the relative angle. Furthermore, the light source body 62 can be used as a diffuse light source by raising and lowering the two blocks, realizing multiple functions and providing convenience for production and maintenance.

[0030] Example 2 This embodiment designs a remotely controlled slit lamp, including a housing 1 and a head support frame 3, a displacement mechanism 2, a support assembly 4, an image acquisition device 7, and the light source structure 6 described in Embodiment 1, all installed inside the housing 1.

[0031] The electrical components of the head support frame 3, displacement mechanism 2, support assembly 4, image acquisition device 7, and light source structure 6 are connected to the controller. The controller communicates with a remote server to remotely control the slit lamp. The controller can be an industrial computer or a PLC. The remote server 9 communicates with the controller via existing network protocols to facilitate the transmission of control commands and collected information. The remote server 9 can communicate with a mobile phone terminal or computer terminal, thus facilitating the control of the slit lamp via the mobile phone terminal or computer terminal 10.

[0032] The case 1 is made of an opaque material. A black curtain 11 can be installed at the front opening of the case 1 to avoid interference from natural light on the eyeglass examination.

[0033] The displacement mechanism 2 includes a transverse module 21 and a longitudinal module 22; the transverse module 21 is mounted on the longitudinal module 22; the longitudinal module 22 is fixed to the inner bottom of the housing 1, and the longitudinal module 22 can control the transverse module 21 to move in the horizontal longitudinal direction. The support assembly 4 is mounted on the transverse module 21, and the transverse module 21 can control the support assembly 4 to move in the horizontal transverse direction.

[0034] The support assembly 4 is mounted on the displacement mechanism 2 and its horizontal movement is controlled by the displacement mechanism 2. The support assembly 4 includes multiple independently rotatable support arms; in this embodiment, the number of support arms is three. The light source structure 6 and the image acquisition device 7 are respectively mounted on different support arms, enabling the light source structure 6 to illuminate from different directions and the image acquisition device 7 to acquire images from different directions. By moving the support assembly 4, the axes of rotation of the light source structure 6 and the image acquisition device 7 can be aligned with the eyeball, thereby allowing the light source structure 6 and the image acquisition device 7 to rotate around the eyeball.

[0035] A head support frame 3 is installed in front of the support assembly 4 and is used for supporting and positioning the human head. The head support frame 3 includes a head bracket 33, on which a chin support 34 for chin positioning and a forehead support 35 for forehead positioning are provided. A telescopic electric cylinder 32 is connected to the bottom of the head bracket 33. Guide rods 31 are provided on opposite sides of the telescopic electric cylinder 32. The upper end of the guide rod 31 is fixed to the head bracket 33, and the lower end is slidably connected to a guide sleeve 36, which is fixed to the bottom wall of the housing 1. When the telescopic electric cylinder 32 moves telescopically, it can adjust the height of the human head, so that the eyes are at the same level as the light source structure 6 or the image acquisition device 7, thus facilitating inspection.

[0036] The support arm includes a horizontal fixed arm 46 and a horizontal sliding arm 47; the horizontal sliding arm 47 is slidably connected to the horizontal fixed arm 46, and a horizontal movement motor is fixed to one end of the horizontal sliding arm 47. A horizontal movement screw 48 connected to the output shaft of the horizontal movement motor is threadedly connected to the horizontal fixed arm 46. The light source structure 6 and the image acquisition device 7 can be mounted on the horizontal sliding arm 47, thereby facilitating the adjustment of the distance between them and the human eyeball.

[0037] The support assembly 4 includes a bottom support 41 and a central tube shaft 42. The lower end of the central tube shaft 42 is connected to the bottom support 41, and the bottom support 41 is fixed on the transverse module 21. The sleeve 43 at the end of the support arm is rotatably fitted onto the central tube shaft 42. The inner wall of the sleeve 43 is provided with internal teeth. The tube wall of the central tube shaft 42 is provided with a reserved hole, and an internal gear 44 is provided inside the central tube shaft 42. The internal gear 44 is driven by an internal motor 45, and the internal gear 44 meshes with the internal teeth of the sleeve 43 at the reserved hole. When the internal motor 45 is powered on, the internal gear 44 can control the rotation of the sleeve 43, thereby controlling the rotation of the support arm and the light source structure 6 and image acquisition device 7 mounted on the support arm.

[0038] A backlight 5 and a distance sensor 8 are provided on one of the support arms of the support assembly 4. The distance sensor 8 is used to detect the distance between the central tube shaft 42 assembly and the human eye, and the backlight 5 is used for supplementary lighting.

[0039] In this embodiment, each component can be controlled by electrical components, which facilitates the automatic change of the position and state of each component, thereby facilitating the acquisition of images of the human eyeball, improving the degree of automation, and reducing the requirements for the use of slit lamps.

[0040] The process of using the remotely controlled slit lamp in this embodiment is as follows: 1. The patient rests their head against the head support frame 3, and then the curtain 11 is closed to reduce interference from natural light.

[0041] 2. The distance sensor 8 is moved to a position directly opposite the eyeball. The height of the patient's head is adjusted using the telescopic electric cylinder 32 so that the height of the patient's eyeball reaches the designated position. The distance between the distance sensor 8 and the patient is adjusted using the displacement mechanism 2 so that the patient's eyeball is directly above the central tube axis 42 and along its axis, thereby enabling the light source structure 6 and the image acquisition device 7 to rotate around the eyeball.

[0042] 3. Rotate the light source structure 6 and the image acquisition device 7, and adjust the distance between the light source structure 6 and the image acquisition device 7 and the eyeball to correspond to different examination items.

[0043] 4. The slit assembly moves up and down to form slit rays or diffuse rays to correspond to different inspections; by changing the relative horizontal position of the first stop 63 and the second stop 64, the width of the slit ray is changed, or the rotation angle of the second stop 64 is changed, so that the slit ray becomes a focused point ray to meet the needs of different inspections.

[0044] 5. The image acquisition device 7 takes pictures of the eyeballs to obtain image information of the patient's eyeballs, so that doctors can judge the patient's symptoms.

[0045] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
