Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical supplies technology, and in particular to a capsule amputation device. Background Technology
[0002] Cataract surgery is an effective way to restore sight. The main surgical procedures are continuous circular capsulorhexis and capsulorhexis; a push-type capsulorhexis device is needed during capsulorhexis. Sometimes, lighting equipment is needed for auxiliary illumination during the procedure. Traditional lighting equipment does not have adjustable functions, making it inconvenient to make specific adjustments according to the actual situation.
[0003] A search revealed a Chinese patent document (authorization announcement number CN218792742U) for a push-type capsulorhexis device used in cataract surgery. The device includes a grip and an anti-slip sleeve. The grip has an anti-slip sleeve on its surface. When the device is needed, the operator installs a lighting lamp inside an extension ring and adjusts the angle of the ball joint at the bottom of the lamp so that the light source is aligned with the bottom of the grip. The operator then places their index finger on the left side of the anti-slip sleeve, and extends the binding strap inside the retractor to secure it to the operator's index finger. Surgery can then begin. The lesion is removed using the cutting forceps at the end of the extension rope. During the surgery, the lighting lamp illuminates the lesion in real time without blind spots, while the binding strap effectively secures the patient's finger, reducing operator fatigue from prolonged gripping. Compared to traditional capsulorhexis devices, this significantly reduces operator fatigue and ensures hand comfort during delicate procedures. However, the lighting device lacks adjustment functionality, making it inconvenient for customized adjustments based on specific needs. Utility Model Content
[0004] The purpose of this invention is to provide a capsulorhexis device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a capsulorhexis device, comprising:
[0006] Injection tube;
[0007] The hollow conical head is threaded to the injection tube, and a bladder-cutting ring is placed inside the conical head;
[0008] Two limiting tubes and two mounting tubes are all set on the outer periphery of the injection tube, and a connecting ring plate is fixedly connected between the limiting tubes and the mounting tubes;
[0009] Multiple movable plates are set between two limit tubes. The sides of the movable plates are connected to clamps, and the clamps are fixed with lighting fixtures. The sides of the movable plates away from the clamps are connected to arc-shaped plates that are adapted to the outer circumference of the injection tube.
[0010] An elastic arc-shaped rubber pad is glued to the side of the arc plate near the injection tube. Two magnets are glued to the outer periphery of the movable plate. The two limit tubes are made of iron material that can attract the magnets.
[0011] As a preferred embodiment, the inner wall of the mounting tube is bonded with an anti-slip pad, and the outer periphery of the mounting tube is provided with multiple threaded channels, which are threadedly connected to a locking threaded rod for fixing.
[0012] As a preferred embodiment, the injection tube is detachably connected to a limiting post by bolts, and the limiting post has two circular channels on its side.
[0013] In a preferred embodiment, a first injection rod and a second injection rod are slidably disposed in the two circular channels respectively, and a push block is connected to the side of both the first injection rod and the second injection rod.
[0014] As a preferred embodiment, the side of the second injection rod away from the push block is connected to the anterior chamber hook.
[0015] As a preferred embodiment, the outer periphery of the injection tube is connected with multiple loops that allow fingers to pass through, and the outer periphery of the injection tube is provided with graduation lines.
[0016] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0017] This endoscopic device includes a lamp for illumination. An arc-shaped plate is positioned between a limiting tube and a injection tube, creating a certain degree of limitation. A magnetic block magnetically engages with the limiting tube, causing the arc-shaped rubber pad to be in a contracted state, thus ensuring the stability of the arc-shaped plate and the lamp. When position adjustment is required, the movable plate is lifted to release the contact between the arc-shaped rubber pad and the injection tube, and the magnetic block and the limiting tube, allowing for left and right position adjustment. This enables different combinations of the positions of multiple lamps to achieve different lighting needs.
[0018] This capsulorhexis device features an adjustable distance between its two mounting tubes, allowing for adjustment of the distance between its two limiting tubes. It is then secured using a threaded rod, meeting various usage needs. Furthermore, its detachable design facilitates maintenance.
[0019] This capsulorhexis device can be adjusted to different degrees to achieve different levels of illumination. Attached Figure Description

[0031] Injection tube 1;
[0032] The hollow conical head 2 is threadedly connected to the injection tube 1, and a bladder-cutting ring 3 is placed inside the conical head 2;
[0033] Two limiting tubes 4 and two mounting tubes 5 are all set on the outer periphery of the injection tube 1, and a connecting ring plate 6 is fixedly connected between the limiting tubes 4 and the mounting tubes 5;
[0034] Multiple movable plates 7 are positioned between two limiting tubes 4. Clamps 8 are connected to the sides of the movable plates 7, and lighting fixtures 9 are fixed to the clamps 8. An arc-shaped plate 10, adapted to the outer periphery of the injection tube 1, is connected to the side of the movable plate 7 away from the clamps 8. An elastic arc-shaped rubber pad 11 is adhered to the side of the arc-shaped plate 10 near the injection tube 1. Two magnets 12 are adhered to the outer periphery of the movable plates 7. Both limiting tubes 4 are made of iron material that can attract the magnets 12. If lighting is not required, the threaded rod 13 can be released. Fix and remove the mounting tube 5, limiting tube 4, and auxiliary structures. If lighting is needed, the lamp 9 can be turned on for illumination. The magnet 12 and the limiting tube 4 are magnetically attracted, so that the arc-shaped rubber pad 11 is in a contracted state, ensuring the stability of the arc-shaped plate 10 and the lamp 9. When position adjustment is needed, lift the movable plate 7 to release the contact between the arc-shaped rubber pad 11 and the injection tube 1, and the magnet 12 and the limiting tube 4, so that the left and right positions can be adjusted, allowing the positions of multiple lamps 9 to achieve different combinations and achieve different lighting needs.
[0035] For adjustment, the inner wall of the mounting tube 5 is bonded with an anti-slip pad, and the outer periphery of the mounting tube 5 is provided with multiple threaded channels, and the threaded channels are threadedly connected with a clamping threaded rod 13 for fixing.
[0036] To facilitate adjustment and capsulotomy, the injection tube 1 is detachably connected to a limiting post 14 via bolts. Two circular channels are formed on the side of the limiting post 14, with a first injection rod 15 and a second injection rod 16 slidably positioned within each channel. Pushing blocks 17 are connected to the sides of both the first and second injection rods 15 and 16. An anterior chamber hook 18 is connected to the side of the second injection rod 16 furthest from the pushing block 17. By passing a finger through a through-ring 19 and pressing the pushing block 17 with another finger, the first injection rod 15 or the second injection rod 16 can be adjusted. Capsulotomy is then performed via the capsulotomy ring 3 and the anterior chamber hook 18. For detailed operation information, please refer to the Chinese patent document (authorization announcement number CN220655785U) detailing the capsulotomy operation of a precisely operable injection-type capsulotomy device.
[0037] The outer periphery of the injection tube 1 is connected with multiple through-rings 19 for easy finger passage, and the outer periphery of the injection tube 1 is provided with scale lines.
[0038] Working principle
[0039] If there is no need for lighting, the screw rod 13 can be released, and the mounting tube 5, limiting tube 4, and auxiliary structures can be removed. If lighting is needed, the lamp 9 can be turned on. The magnet 12 and the limiting tube 4 are magnetically attracted, so that the arc-shaped rubber pad 11 is in a contracted state, ensuring the stability of the arc-shaped plate 10 and the lamp 9. When position adjustment is needed, the movable plate 7 is lifted to release the contact between the arc-shaped rubber pad 11 and the injection tube 1, and the magnet 12 and the limiting tube 4, so that the left and right positions can be adjusted, and the positions of multiple lamps 9 can be combined in different ways to achieve different lighting needs.
[0040] By passing a finger through the piercing ring 19 and pressing the push block 17 with another finger, the first injection rod 15 or the second injection rod 16 is adjusted, and the cystectomy is performed through the cystectomy ring 3 and the anterior chamber hook 18.
