Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical models, in particular to a laser vitreous ablation model for floaters. Background Art
[0002] Floaters are opacities or foreign bodies in the vitreous humor inside the eye, typically appearing as black spots, lines, or small particles floating across the field of vision. These floaters are actually gelatinous or fibrous structures within the vitreous humor that cast shadows as they move back and forth across the retina, interfering with vision. Floaters are often caused by aging or eye disease. While generally harmless, sudden or frequent onset of these floaters should prompt medical attention.
[0003] Chinese patent publication number CN219246263U discloses an eyeball model for demonstrating ocular pathology. This model, by shaking the container to mix the clarified liquid and precipitate into a suspension, vividly simulates the turbidity caused by vitreous pathology. Lasers are then focused on the turbidity to achieve simulated ablation of the turbidity, such as floaters. Compared to existing eyeball models, this model can more vividly demonstrate ocular pathology, making it easier for lecturers to explain ocular pathology in a more vivid way.
[0004] Although the above patent can vividly demonstrate floaters, it cannot help patients or students better understand the treatment principle of vitreous ablation, thus reducing the effectiveness of the explanation. Utility Model Content
[0005] The utility model aims to provide a vitreous ablation model for floaters, which can simulate the symptoms of floaters and the treatment principle of vitreous ablation.
[0006] To achieve the above objectives, the technical solution of the present utility model is as follows.
[0007] A laser vitreous body ablation model for floaters includes an eyeball model, a light projector, and a base. The outer surface of the eyeball model is provided with a cornea, the outer surface of the base is provided with an L-shaped plate, the light projector is arranged at the end of the L-shaped plate, the upper surface of the base is installed with a support rod, the lower side of the eyeball model is installed with a connecting sleeve, and a connecting mechanism is provided between the end of the support rod and the connecting sleeve.
[0008] It can be seen that the light projector can switch between red light and white light. Red light is a laser straight line, and white light is diffuse. Therefore, by projecting white light from the cornea into the inside of the eyeball model, the symptoms of floaters can be simulated. The main treatment for floaters is laser ablation, which is safe, non-invasive and has few complications. Therefore, by projecting red light from the cornea into the inside of the eyeball model, the treatment process of vitreous ablation can be simulated, making the explanation process more vivid and improving the explanation effect. Through the setting of the connecting mechanism, the eyeball model and the support rod can be disassembled and assembled, which is convenient for disassembly when carrying, reducing the occupied space and improving the portability.
[0009] Furthermore, the connecting mechanism includes an inner groove opened inside the support rod, an insertion rod is provided inside the inner groove, a spring is provided inside the inner groove, both ends of the spring are respectively abutted against the insertion rod and the inner wall of the inner groove, and a socket is opened on the surface of the connecting sleeve, and the insertion rod is adapted to the socket.
[0010] When the eyeball model needs to be removed from the support rod, the socket can be pressed inward to shrink its end into the connecting sleeve, and then the connecting sleeve can be separated from the support rod to complete the removal of the eyeball model. When the eyeball model needs to be installed on the support rod, the insertion rod can be pressed inward to shrink its end into the inner groove, and then the end of the support rod can be inserted into the connecting sleeve. When the insertion rod is aligned with the socket, the compressed spring releases the elastic force, so that the insertion rod can be pushed into the socket to achieve the installation of the eyeball model.
[0011] Furthermore, a first damping shaft is installed on the upper surface of the L-shaped plate, a first U-shaped block is installed at the end of the first damping shaft, a second damping shaft is installed on the inner walls on both sides of the first U-shaped block, and the end of the second damping shaft is connected to the light projector.
[0012] By setting the first damping rotating shaft and the second damping rotating shaft, the angle of the light projector can be adjusted arbitrarily to simulate the purpose of ablating floaters at different positions.
[0013] Furthermore, a second U-shaped block is installed on the upper surface of the base, and a bolt is installed on the upper surface of the second U-shaped block.
[0014] The second U-shaped block and the bolts can be used to fix the L-shaped plate, so that the plate can be disassembled when carried.
[0015] Furthermore, a limiting groove is provided on the outer surface of the support rod along its height direction, and a limiting block is provided on the inner wall of the connecting sleeve, and the limiting block is adapted to the limiting groove.
[0016] By setting the limiting groove and the limiting block, the angle can be limited when the support rod is inserted into the connecting sleeve, ensuring that the rod and the socket can be accurately aligned.
[0017] Furthermore, a viewing window is provided on the upper side of the eyeball model.
[0018] Through the setting of the viewing window, it can be easily displayed and people can directly observe it. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] The present invention is described in detail below with reference to the accompanying drawings.
[0025] like Figure 1-4 As shown, a model for laser vitreous ablation of floaters includes an eyeball model 100, a light projector 102, and a base 103. The outer surface of the eyeball model 100 is provided with a cornea 101, the outer surface of the base 103 is provided with an L-shaped plate 105, the light projector 102 is provided at the end of the L-shaped plate 105, the upper surface of the base 103 is installed with a support rod 104, the lower side of the eyeball model 100 is installed with a connecting sleeve 106, and a connecting mechanism 200 is provided between the end of the support rod 104 and the connecting sleeve 106.
[0026] When simulating floaters, the light projector 102 can be switched to white light. White light is diffuse, so by projecting white light from the cornea 101 into the eye model 100, the symptoms of floaters can be simulated. When simulating vitreous ablation treatment for floaters, the light projector 102 can be switched to red light. Red light is a straight laser beam. By projecting red light from the cornea 101 into the eye model 100, the vitreous ablation treatment process can be simulated, making the explanation more vivid and effective. It is worth noting that the medical term for floaters is vitreous opacities. Common treatments include medication, laser, and minimally invasive vitreous surgery. Medication is often ineffective. While vitreous surgery can effectively eliminate floaters, it requires intraocular access and is invasive. Therefore, its disadvantages are significant, including the risk of purulent infection, and the benefits are disproportionate to the risks. Vitreous laser ablation is more effective than medication and safer than surgery, being non-invasive and having fewer complications. Floaters are vitreous opacities, which are essentially protein aggregation. Lasers with higher energy density can be used to break the disulfide bonds between proteins, causing them to be completely vaporized, producing gases similar to ammonia and hydrogen, completely eliminating the floaters. The connection mechanism 200 allows for assembly and disassembly of the eyeball model 100 and the support rod 104, making it easier to disassemble them when carrying, reducing space occupied and improving portability.
[0027] In the second embodiment, the cornea 101 and the light projector 102 are magnetically connected, and the magnetic connection with the switch is convenient for demonstration and easy to carry.
[0028] Specifically, the connecting mechanism 200 includes an inner groove 201 provided inside the support rod 104, an insertion rod 202 is provided inside the inner groove 201, a spring 203 is provided inside the inner groove 201, and the two ends of the spring 203 are respectively in contact with the insertion rod 202 and the inner wall of the inner groove 201. A socket 204 is provided on the surface of the connecting sleeve 106, and the insertion rod 202 is adapted to the socket 204. When the eyeball model 100 needs to be removed from the support rod 104, the socket 204 can be pressed inward to shrink the end thereof to the connecting sleeve 106. 06, the connecting sleeve 106 can be separated from the support rod 104 to complete the removal of the eyeball model 100. When the eyeball model 100 needs to be installed on the support rod 104, the insertion rod 202 is pressed inward to retract its end into the inner groove 201, and then the end of the support rod 104 is inserted into the connecting sleeve 106. When the insertion rod 202 is aligned with the insertion hole 204, the compressed spring 203 releases the elastic force, so that the insertion rod 202 can be pushed into the insertion hole 204 to achieve the installation of the eyeball model 100.
[0029] Specifically, a first damping shaft 300 is installed on the upper surface of the L-shaped plate 105, a first U-shaped block 301 is installed at the end of the first damping shaft 300, and a second damping shaft 302 is installed on the inner walls on both sides of the first U-shaped block 301. The end of the second damping shaft 302 is connected to the light projector 102. Through the setting of the first damping shaft 300 and the second damping shaft 302, the angle of the light projector 102 can be adjusted at will to simulate the purpose of ablating floaters in different positions.
[0030] Specifically, a second U-shaped block 400 is installed on the upper surface of the base 103, and a bolt 401 is installed on the upper surface of the second U-shaped block 400. Through the arrangement of the second U-shaped block 400 and the bolt 401, the L-shaped plate 105 can be fixed to achieve the purpose of disassembly when carrying.
[0031] Specifically, a limiting groove 500 is provided on the outer surface of the support rod 104 along its height direction, and a limiting block 501 is provided on the inner wall of the connecting sleeve 106, and the limiting block 501 is adapted to the limiting groove 500. By setting the limiting groove 500 and the limiting block 501, the angle can be limited when the support rod 104 is inserted into the connecting sleeve 106, ensuring that the insertion rod 202 and the socket 204 can be accurately aligned.
[0032] Specifically, a viewing window 600 is provided on the upper side of the eyeball model 100 , and the viewing window 600 can be conveniently displayed and directly observed by people.
[0033] The above is a detailed description of the present invention in conjunction with specific embodiments, and the specific implementation methods of the present invention are not limited to these descriptions. For those skilled in the art of the present invention, if a number of equivalent substitutions or obvious modifications are made without departing from the concept of the present invention and have the same performance or use, they should be considered to fall within the scope of patent protection of the present invention as determined by the submitted claims.
