Description

Technical Field

[0001] This utility model relates to the field of intraocular lens repositioning technology, specifically to an intraocular lens repositioning hook with infusion. Background Technology

[0002] An intraocular lens (IOL) is an artificial device used to replace the eye's natural lens, typically in cataract surgery or other surgeries that require the removal or replacement of the natural lens. When the eye's natural lens becomes cloudy or malfunctions due to causes such as cataracts, doctors remove it and implant an IOL to restore vision. During cataract surgery, after the IOL is implanted, doctors may use an IOL repositioning hook to rotate and adjust its position. An IOL repositioning hook is a surgical tool primarily used to adjust or reposition the implanted IOL during cataract surgery or other surgeries involving IOL implantation. If the IOL is not properly aligned or positioned ideally after implantation, doctors can use the repositioning hook to fine-tune its position, ensuring it is in optimal condition for best visual results.

[0003] In the prior art, when adjusting the position of an intraocular lens using an adjustment hook, the handle of the adjustment hook is generally fixed. This makes it difficult for medical staff to adjust the length of the handle according to the needs and habits of the operation, resulting in a lack of flexibility and convenience in the use of the adjustment hook, and also hindering the improvement of the comfort of the operation. Therefore, in order to solve the above problems, an intraocular lens adjustment hook with perfusion is proposed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] An intraocular lens positioning hook with irrigation function includes a housing, a first handle 1, a second handle 11 on the surface of the first handle 1, a connecting post 12 at the end of the first handle 1 away from the second handle 11, a hook head 13 fixedly connected to the end of the connecting post 12 away from the first handle 1, an irrigation inlet 14 fixedly connected to the surface of the connecting post 12, and an irrigation outlet 15 opened on the inner side of the hook head 13. The first handle 1 and the second handle 11 facilitate handholding by medical personnel, the hook head 13 can be used to adjust the position of the intraocular lens during intraocular surgery, and the irrigation inlet 14 and the irrigation outlet 15 can be used to infuse liquid, thus making the operation more convenient.

[0025] An adjustment mechanism is provided on the surface of the first handle 1. The adjustment mechanism includes a fixed rod 2, which is fixedly connected to the surface of the first handle 1. A first movable groove 22 is provided on the inner side of the second handle 11. The fixed rod 2 and the first movable groove 22 are movably connected. A second movable groove 24 is provided on the inner wall of the first movable groove 22. A spring 25 is fixedly connected to the inner wall of the second movable groove 24. A locking block 26 is fixedly connected to the surface of the spring 25. A locking groove 27 is provided on the inner side of the fixed rod 2. By opening the locking groove 27, the position of the second handle 11 can be adjusted when the locking block 26 engages and disengages with the different locking grooves 27. This allows for adjustment of the overall length of the first handle 1 and the second handle 11, making the use of the adjustment hook more flexible and facilitating the adjustment of the intraocular lens through the hook head 13.

[0026] Furthermore, the adjustment mechanism also includes a slide groove 21, which is opened on the inner side of the fixed rod 2. A connecting block 23 is fixedly connected to the inner wall of the first movable groove 22. The connecting block 23 and the slide groove 21 are movably connected. By opening the slide groove 21 and setting the connecting block 23, the second handle 11 can move stably on the surface of the fixed rod 2, thereby ensuring the accuracy of the engagement of the locking block 26 and the locking groove 27.

[0027] Furthermore, the second movable groove 24 is formed in two sets on the inner wall of the first movable groove 22. One end of the spring 25 is fixedly connected to the second movable groove 24, and the other end of the spring 25 is fixedly connected to the locking block 26. Through the elastic properties of the spring 25, the locking block 26 can extend and retract inside the second movable groove 24, thereby facilitating the locking block 26 and the locking groove 27 to engage and disengage.

[0028] Furthermore, the locking block 26 moves inside the second movable groove 24, the slide groove 21 is opened in two sets inside the fixed rod 2, and the connecting block 23 is fixedly connected to the first movable groove 22 in two sets. By opening the slide groove 21, the connecting block 23 can slide in the slide groove 21 when the length of the second handle 11 is adjusted, which can ensure the stability of the adjustment of the second handle 11.

[0029] Furthermore, the surface of the connecting post 12 is provided with an auxiliary mechanism, which includes a mounting rod 3. The mounting rod 3 is fixedly connected to the end of the connecting post 12 away from the hook head 13. The inner side of the first handle 1 is provided with a mounting groove 31, and the surface of the first handle 1 is provided with anti-slip texture 32. Through the cooperation of the mounting rod 3 and the mounting groove 31, it is convenient to install and remove the connecting post 12 as a whole, so as to facilitate the replacement or storage of the connecting post 12 as a whole, making the use of the adjustment hook more convenient.

[0030] Furthermore, the mounting rod 3 and the mounting groove 31 are connected by threads, and the anti-slip texture 32 is set on the surface of the first handle 1 and the second handle 11. By setting the anti-slip texture 32, the friction between the medical staff's hands and the first handle 1 and the second handle 11 can be increased, thus making the grip more stable.

[0031] Working principle: When in use, pull the second handle 11 to move the second handle 11 on the surface of the fixed rod 2, and then the fixed rod 2 moves in the first movable groove 22. At the same time, the connecting block 23 slides in the slide groove 21. During the movement of the second handle 11, the locking block 26 is squeezed and moves into the second movable groove 24. At this time, the spring 25 is in a contracted state, which can separate the locking block 26 from the corresponding locking groove 27. When the movement of the second handle 11 makes the locking block 26 face other locking grooves 27, the locking block 26 can be reset under the rebound action of the spring 25, and thus the locking block 26 and the locking groove 27 can be engaged, thereby realizing the adjustment and fixation of the second handle 11.

[0032] Rotating the connecting post 12 allows it to connect and separate from the first handle 1 under the action of the mounting rod 3 and the mounting groove 31, thus facilitating the installation, storage, or replacement of the connecting post 12 as a whole. The anti-slip texture 32 increases the friction between the hand and the surface of the first handle 1 and the second handle 11, resulting in better grip stability.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
