[0029] 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.

[0030] Reference Figures 1-3 One embodiment of this utility model provides a handle 1, which supports the entire device and, through its stable structure, ensures good operational balance of the entire surgical apparatus. A limiting groove 9 is provided on one side of the handle 1 to limit the sliding range of the extension rod 2, ensuring the stability and accuracy of the extension rod 2 and preventing unnecessary displacement during surgery.

[0031] Extension rod 2, with a hook 3 fixedly connected to one end, is used to adjust the distance between the hook 3 and the handle 1. By adjusting the extension rod 2, the surgeon can freely change the operating distance of the surgical hook according to different surgical needs and the patient's physical condition, thereby achieving more precise surgical operations.

[0032] Threaded sleeve 4, used to connect the adjusting sleeve, is installed inside the handle 1 and connects the extension rod 2 to the handle 1. The threaded engagement makes the entire adjusting system more secure and stable. The design of threaded sleeve 4 provides flexibility, ensuring that the position of the extension rod 2 can be stably locked during adjustment, preventing loosening or displacement during surgery.

[0033] Clamping blocks 5 are arranged in a ring array at one end and fixedly connected to one end of threaded sleeve 4. Clamping blocks 5 are used to fix extension rod 2. When fastening sleeve 6 is tightened, clamping blocks 5 clamp and fix extension rod 2 through tight contact of the inner wall, effectively preventing extension rod 2 from slipping or loosening during operation and ensuring the stability of surgical hook;

[0034] The fastening sleeve 6 is threaded onto the outer wall of the threaded sleeve 4 and is used to fix the extension rod 2 via the clamping block 5. Tightening and loosening the fastening sleeve 6 controls the adjustment of the extension rod 2, and in conjunction with the clamping block 5, makes adjustment and fixation more reliable. The fastening sleeve 6 has an inner conical groove 7 that fits snugly against the outer wall of the clamping block 5, achieving precise fixation and ensuring that the extension rod 2 does not shift during surgery. The handle 1 has a limiting groove 9 inside, and the extension rod 2 slides within the limiting groove 9. The limiting groove 9 effectively limits the maximum sliding range of the extension rod 2, preventing excessive sliding that could render it unusable. The design of the limiting groove 9 enables more precise adjustment and control. The other end of the threaded sleeve 4 is fixedly connected to one end of the handle 1, enhancing the stability and tightness of the entire device. This allows the extension rod 2 to move stably under the guidance of the handle 1 and ensures that the position of the extension rod 2 remains accurate during adjustment. The fastening sleeve 6 has an inner conical groove 7 inside, which fits against the outer wall of the clamping block 5. The design of the inner conical groove 7 increases the contact area between the clamping block 5 and the extension rod 2, making the clamping force more uniform and thus improving the fixing effect. The outer wall of the handle 1 is fixedly connected with convex rings 8 arranged in a linear array. The convex rings 8 effectively prevent slippage during operation, making the handle 1 more non-slip and stable, and facilitating doctors to hold and operate it for extended periods during surgery.

[0035] Specifically, when it is necessary to extend the distance between the hook head 3 and the handle 1, the operation is very simple and flexible. First, by rotating the fastening sleeve 6, it is separated from the handle 1, releasing the connection between the fastening sleeve 6 and the clamping block 5, allowing the clamping block 5 to be effectively released. At this time, the user can adjust the position of the extension rod 2 inside the handle 1 to the desired position. After adjustment, rotate the fastening sleeve 6 again so that the inner wall of its inner conical groove 7 fits tightly against the outer wall of the clamping block 5. Through this tight fit, the clamping block 5 will re-clamp and fix the extension rod 2, ensuring that the stable position of the extension rod 2 does not slip. At this time, the user can use the handle 1 to operate it, and through the anti-slip design of its convex ring 8, effectively prevent the handle 1 from slipping, so as to safely and stably drive the hook head 3 to perform precise surgical operations on the patient. Through this simple and efficient adjustment method, not only can the usable length of the hook head 3 be easily extended, but the safety and precision of the surgical operation are also ensured, greatly improving the ease of use of the equipment.

[0036] Working principle: When using this multifunctional cataract surgery device and its surgical hook, if it is necessary to extend the distance between the hook head 3 and the handle 1, simply rotate the fastening sleeve 6 to separate the fastening sleeve 6 from the handle 1, and then the clamping block 5 is released. After adjusting the position of the extension rod 2 in the handle 1, rotate the fastening sleeve 6 to make the inner wall of the inner conical groove 7 fit against the outer wall of the clamping block 5, so that the clamping block 5 clamps and fixes the extension rod 2. Then, the hook head 3 can be driven by the handle 1 to perform surgical operations on the patient. The handle 1 is anti-slip through the convex ring 8, which makes it easy to adjust the length of the hook head 3.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
