Description

Technical Field

[0001] This invention belongs to the field of capsulorhexis surgery technology, and particularly relates to a continuous ring capsulorhexis surgery practice model for cataracts. Background Technology

[0002] Cataracts are caused by various factors such as aging, genetics, local nutritional deficiencies, immune and metabolic abnormalities, trauma, poisoning, and radiation. These factors can disrupt the metabolism of the lens, leading to protein denaturation and clouding of the lens, a condition known as cataracts. In this state, light is blocked by the cloudy lens and cannot reach the retina, resulting in blurred vision. It is most common in people over 40 years of age, and the incidence increases with age.

[0003] A search revealed that application number CN202310650354.X discloses a continuous ring-shaped capsulorhexis surgery practice model for cataracts, including an eyeball model, a membrane, a corneal incision model, and an eye movement device. The eyeball model includes a hollow hemisphere and a filler material inside the hollow hemisphere. A hole is opened at the center of the top of the hollow hemisphere, and a first magnet is embedded in the hollow hemisphere. The corneal incision model includes a tubular body, and a second magnet that attracts the first magnet is embedded in the tubular body. The eye movement device includes a connecting part, one end of which is connected to the bottom of the hollow hemisphere. The membrane covers the upper surface of the hollow hemisphere. When the first magnet and the second magnet are attracted, the membrane is clamped and fixed between the eyeball model and the corneal incision model. The above invention is not only easy to use and has no storage problems, but the membrane sheet is also easy to replace. Moreover, the only part that needs to be replaced in the entire surgical practice model is the membrane sheet, thus reducing costs and facilitating training and promotion.

[0004] The problem with the above-mentioned technical solutions is that, in current cataract surgery, medical staff need to practice with a surgical model. However, the existing surgical model is too bulky to be easily folded and stored, which reduces the practicality of the device. Furthermore, it requires manual adjustment by medical staff during use, which can delay the surgical treatment process. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a cataract continuous ring capsulotomy surgery practice model that can overcome or at least partially solve the above problems.

A motor is fixedly connected to the lower end of one lead screw, and the motor is fixedly mounted on the lower surface of the second mounting component.

[0007] Preferably, two bases are fixed to the lower outer side of the outer shell of the box, and bolt mounting plates are fixedly connected to the rear and side surfaces of the bases. One side of the outer shell of the box is open, and a groove is provided on the lower side of the same side of the outer shell of the box. A support ejection assembly is installed inside the outer shell of the box, and a protective plate is installed on the support ejection assembly. The protective plate is provided with a number of evenly distributed protective holes, and a fixing plate is also installed above the support ejection assembly.

[0008] Preferably, a lifting and adjusting component is also installed on the supporting ejection component, and a carrying plate is installed on the lifting and adjusting component. The carrying plate is located above the fixed plate. A surgical magnifying glass is fixedly connected to the upper surface of the carrying plate. An eye mounting shell is fixedly connected to the upper surface of the surgical magnifying glass. An eye probe is installed on one side of the eye mounting shell, and a magnifying probe is installed below the surgical magnifying glass.

[0009] Preferably, a support block is rotatably mounted on the other end of each connecting shaft. The support block is fixedly connected to the lower surface of the fixed plate. Slide grooves are provided on both sides of the front of the fixed plate. Limit blocks are installed in the slide grooves on both sides. A first transmission rod is rotatably mounted on the lower surface of the limit block. A main shaft is rotatably mounted on the lower end of the first transmission rod on both sides.

[0010] Preferably, mounting sheet metal is rotatably mounted at both ends of the main shaft, and a first slider is fixedly connected to the outer side of the mounting sheet metal on both sides. A first slide rail is movably mounted on one side of the first slider on both sides. The first slide rail is fixedly connected to the inner surface of the front side support rod. An electric push rod output shaft is rotatably mounted in the middle of the main shaft. A push rod mounting plate is fixedly connected to one side of the electric push rod. The push rod mounting plate is installed in a second slide rail. The second slide rail is fixedly connected to the inner wall of the housing shell.

[0011] Preferably, the upper ends of the two front side support rods are fixedly connected to extension rods, one end of the two side extension rods is rotatably mounted with a connecting side plate, the lower end of the two side connecting side plates is rotatably mounted with a protective plate, and a fixing block is fixedly connected to the rear of the protective plate.

[0012] Preferably, a first mounting groove is provided on both sides of the fixing block, a second transmission rod is rotatably installed in the first mounting groove, the other end of the second transmission rod is rotatably installed on a first mounting component, and the first mounting components on both sides are rotatably installed on the main shaft.

[0013] Preferably, sprockets are fixedly sleeved at the lower ends of the lead screws on both sides, and chains are driven and installed on the sprockets on both sides. Threaded rods are threadedly engaged at the upper ends of the lead screws on both sides. An installation block is provided at the upper end of the threaded rod. A second installation groove is provided on one side of the installation block. The threaded rod is rotatably installed in the second installation groove. A third slide rail is fixedly connected to the upper surface of the installation blocks on both sides. A second slider is installed in the third slide rail. The second slider is fixedly connected to one side of the limiting block.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention drives the main shaft through an electric push rod. Since the mounting sheet metal at both ends of the main shaft and the first slider are located in the first slide rail, and the first slide rail is fixedly connected to the side support rod, the connecting sheet metal at the lower end of the side support rod can be driven to move forward around the mounting seat. Since the main shaft is also equipped with a limit block through the first transmission rod, and the limit block is installed in the slide groove, the limit block can be driven to move along the slide groove. The upper surface of the limit block is fixedly connected to a bearing plate, which can be driven to extend the bearing plate to the outside of the housing. Since the side support rod is equipped with a protective plate through the extension rod and the connecting side plate, and the second transmission rod is installed through the first mounting part on the main shaft, and the second transmission rod is installed in the first mounting groove of the first mounting part and the fixed block, the protective plate can be pushed to move to the bottom of the magnifying probe through one end of the extension rod, thus protecting the magnifying probe and also enabling the practice model to be folded and stored.

[0015] 2. The electric push rod of this invention, in conjunction with the support ejection assembly, can move the carrier plate from inside the housing to the front of the housing. Subsequently, it can also be linked to push the protective plate to the underside of the magnifying probe below the carrier plate, thus protecting the magnifying probe and surgical magnifying glass. This can then move the magnifying probe above the practice eye model, and the motor drives the lead screw to rotate. Since the lead screws on both sides rotate through sprockets and chains, and since the lead screws are threadedly engaged with the threaded rod, they can drive the mounting block and the third slide rail to move up and down. Furthermore, since the third slide rail is mounted on the second slider, and since the upper end of the third slide rail is fixedly connected to the carrier plate, it can be adjusted by moving it up and down.

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 8As shown in the figure, an embodiment of the present invention provides a cataract continuous ring capsulotomy surgery practice model, including a box shell 1, a support ejection assembly 12, and a lifting adjustment assembly 13. The support ejection assembly 12 includes a mounting base 201, which is fixedly connected to the four corners of the inner wall of the box shell 1. Each mounting base 201 is rotatably mounted with a connecting sheet metal 202, and each connecting sheet metal 202 is rotatably mounted with a side support rod 203 at its upper end.

One side of the outer shell 1 is open. A groove 4 is provided on the lower side of the same side of the outer shell 1. A support ejection assembly 12 is installed inside the outer shell 1. A protective plate 5 is installed on the support ejection assembly 12. The protective plate 5 has several evenly distributed protective holes 11. A fixing plate 14 is also installed above the support ejection assembly 12. A lifting adjustment assembly 13 is also linked to the support ejection assembly 12. A support plate 6 is installed on the lifting adjustment assembly 13. The support plate 6 is located above the fixing plate 14. A surgical magnifying glass 8 is fixedly connected to the upper surface of the support plate 6. An eye mounting housing 9 is fixedly connected to the device. An eye probe 10 is mounted on one side of the eye mounting housing 9, and a magnifying probe 7 is mounted below the surgical magnifying glass 8. First, the prepared practice eye model is placed in front of the device. Then, the electric push rod 213, in conjunction with the support ejection component 12, can move the support plate 6 from inside the housing 1 to the front of the housing 1. Subsequently, it can also be linked to push the protective plate 5 to move below the magnifying probe 7 under the support plate 6, thus protecting the magnifying probe 7 and the surgical magnifying glass 8. This allows the magnifying probe 7 to be moved above the practice eye model. Then, the motor 305, in conjunction with the lifting adjustment component 13, can adjust the height of the support plate 6, so that the magnifying probe 7 is close to the eye model, allowing for faster practice of capsulorhexis surgery.

[0022] Each connecting shaft 204 has a support block 205 rotatably mounted at its other end. The support block 205 is fixedly connected to the lower surface of the fixing plate 14. Slide grooves 207 are provided on both sides of the front of the fixing plate 14. Limiting blocks 206 are installed in the slide grooves 207 on both sides. A first transmission rod 208 is rotatably mounted on the lower surface of the limiting block 206. A main shaft 209 is rotatably mounted at the lower end of the first transmission rod 208 on both sides. Mounting sheet metal 210 is rotatably mounted at both ends of the main shaft 209. A first slider 211 is fixedly connected to the outer side of the mounting sheet metal 210 on both sides. A first slide rail 212 is movably mounted on one side of the first slider 211 on both sides. The first slide rail 212 is fixedly connected to the front side. On the inner surface of the side support rod 203, an electric push rod 213 output shaft is rotatably mounted in the middle of the main shaft 209. A push rod mounting plate 214 is fixedly connected to one side of the electric push rod 213. The push rod mounting plate 214 is installed in the second slide rail 215. The second slide rail 215 is fixedly connected to the inner wall of the housing 1. Extension rods 221 are fixedly connected to the upper ends of the two front side support rods 203. Connecting side plates 216 are rotatably mounted at one end of the two side extension rods 221. Protective plates 5 are rotatably mounted at the lower ends of the two side connecting side plates 216. A fixing block 217 is fixedly connected to the rear of the protective plate 5. A first mounting groove 218 is provided on both sides of the fixing block 217. A second transmission rod 219 is rotatably mounted in the groove 218. The other end of the second transmission rod 219 is rotatably mounted on a first mounting component 220. The first mounting components 220 on both sides are rotatably mounted on the main shaft 209. The main shaft 209 is pushed by an electric push rod 213. Since the mounting sheet metal 210 and the first slider 211 at both ends of the main shaft 209 are located in the first slide rail 212 and the first slide rail 212 is fixedly connected to the side support rod 203, the connecting sheet metal 202 at the lower end of the side support rod 203 can be driven to move forward around the mounting base 201. Since a limit block 206 is also mounted on the main shaft 209 through the first transmission rod 208, and the limit block 206 is mounted in the groove 20 Within 7, the limiting block 206 can be moved along the slide 207. The upper surface of the limiting block 206 is fixedly connected to the bearing plate 6, which can be moved to extend the bearing plate 6 to the outside of the housing 1. Since the protective plate 5 is installed in front of the side support rod 203 through the extension rod 221 and the connecting side plate 216, and the second transmission rod 219 is installed through the first mounting part 220 on the main shaft 209, and the second transmission rod 219 is installed in the first mounting groove 218 of the first mounting part 220 and the fixing block 217, the protective plate 5 can be pushed to move to the bottom of the magnifying probe 7 through one end of the extension rod 221, which can protect the magnifying probe 7 and also make the practice model foldable and foldable.

[0023] Sprockets 303 are fixedly sleeved at the lower ends of the lead screws 302 on both sides. Chains 304 are driven onto the sprockets 303 on both sides. Threaded rods 306 are threadedly connected to the upper ends of the lead screws 302 on both sides. Mounting blocks 307 are provided at the upper ends of the threaded rods 306. A second mounting groove 308 is provided on one side of the mounting block 307. The threaded rod 306 is rotatably mounted in the second mounting groove 308. A third slide rail 309 is fixedly connected to the upper surface of the mounting blocks 307 on both sides. A third slide rail 309 is installed in the third slide rail 309. There is a second slider 310, which is fixedly connected to one side of the limiting block 206. The motor 305 drives the lead screw 302 to rotate. Since the lead screws 302 on both sides rotate through the sprocket 303 and the chain 304, and since the lead screw 302 is threadedly engaged with the threaded rod 306, it can drive the mounting block 307 and the third slide rail 309 to move up and down. Since the third slide rail 309 is installed on the second slider 310, and since the upper end of the third slide rail 309 is fixedly connected to the bearing plate 6, it can be driven to move up and down for adjustment.

[0024] The working principle of this invention is as follows: In use, the prepared eye model is first placed in front of the device. The main shaft 209 is pushed by the electric push rod 213. Since the mounting sheet metal 210 and the first slider 211 at both ends of the main shaft 209 move within the first slide rail 212, and the first slide rail 212 is fixedly connected to the side support rod 203, the connecting sheet metal 202 at the lower end of the side support rod 203 can move forward around the mounting base 201. Because the main shaft 209 is also connected to the first transmission... A limiting block 206 is installed on rod 208, and the limiting block 206 is installed in the slide groove 207, which can drive the limiting block 206 to move along the slide groove 207. A bearing plate 6 is fixedly connected to the upper surface of the limiting block 206, which can drive the bearing plate 6 to extend to the outside of the housing shell 1. Since a protective plate 5 is installed in front of the side support rod 203 through the extension rod 221 and the connecting side plate 216, a second transmission rod 219 is installed through the first mounting part 220 on the main shaft 209, and the second transmission rod 219... Installed in the first mounting slot 218 of the first mounting component 220 and the fixing block 217, the protective plate 5 can be moved to the underside of the magnifying probe 7 via one end of the extension rod 221, thus protecting the magnifying probe 7. Subsequently, it can be linked to move the protective plate 5 to the underside of the magnifying probe 7 below the support plate 6, thus protecting the magnifying probe 7 and the surgical magnifying lens 8. This allows the magnifying probe 7 to be moved above the practice eye model, and then the motor 305 drives the lead screw 302 to rotate. Since the lead screws 302 on both sides rotate through the sprocket 303 and the chain 304, and since the lead screws 302 are threadedly engaged with the threaded rod 306, they can drive the mounting block 307 and the third slide rail 309 to move up and down. Since the third slide rail 309 is installed on the second slider 310, and since the upper end of the third slide rail 309 is fixedly connected to the support plate 6, it can be adjusted up and down, so that the magnifying probe 7 is close to the eye model, allowing for faster practice of capsulorhexis surgery.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can exercise their rights without departing from the scope of the present invention.
