[0002] An artificial lens, also known as an intraocular lens, is a precision optical component that is surgically implanted into the eye to replace the removed, cloudy lens. Artificial lens implantation is the most effective treatment for cataracts, and thousands of cataract patients have regained good vision through this safe and effective surgical method.

[0003] Application number "CN202321751215.8" describes a device for adjusting an intraocular lens (IOL) in a phakic eye. This device comprises a handle, a support rod, and an adjustment mechanism. The adjustment mechanism consists of a first adjustment rod, a second adjustment rod, a connecting rod, a cross-section, and an adjustment head. The adjustment head is formed at the bottom of the cross-section at the end of the second adjustment rod and has an arc-shaped structure, resulting in gentle adjustment with minimal discomfort. The device utilizes an infusion device that works with the infusion tube and infusion port, and an expulsion device that works with the discharge tube and suction port to achieve the functions of adjustment, infusion, and expulsion.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a device for adjusting the position of an intraocular lens in a phakic eye, including an installation cylinder 1, an infusion cylinder 4 and an outlet cylinder 5 inside the installation cylinder 1, an installation plate 2 on one side of the installation cylinder 1, and a plurality of locking strips 3 fixedly connected to one side of the installation plate 2. A plurality of locking grooves are provided on the inner wall of the installation cylinder 1. By setting the locking strips 3 and locking grooves, the installation plate 2 can be easily disassembled, so that the first piston rod 8, the first piston 6, the second piston rod 9, and the second piston 7 can be separated from the infusion cylinder 4 and the outlet cylinder 5, thereby cleaning the infusion cylinder 4 and the outlet cylinder 5.

[0026] An injection pipe 11 is provided on one side of the injection cylinder 4, and a discharge pipe 12 is provided on one side of the discharge cylinder 5. A support rod 10 is fixedly connected to one side of the mounting cylinder 1. Rotating blocks 14 are rotatably connected to both sides of the support rod 10. An adjusting head 15 is fixedly connected to one side of the rotating block 14. An adjusting rope 13 is fixedly connected to one side of the adjusting head 15. A limiting plate 18 is fixedly connected to the upper end of the mounting cylinder 1. One end of the adjusting rope 13 passes through the support rod 10, the mounting cylinder 1, and the limiting plate 18, and is locked to one side of the limiting plate 18. By setting the rotating block 14 and the adjusting rope 13, the adjusting head 15 is driven to rotate. Its tilt angle is adjusted before use to improve the versatility of the device.

[0027] The mounting plate 2 is connected to the mounting cylinder 1 via a locking strip 3 for disassembly. Pulling the mounting plate 2 outward causes the tapered head of the locking strip 3 to bend the connecting rod, thus disengaging it from the slot and achieving disassembly. The infusion cylinder 4 contains a first piston 6, with a first piston rod 8 fixedly connected to one side. Pressing the first piston rod 8 moves the first piston 6, facilitating the infusion of the infusion fluid into the eye. The first piston rod 8 penetrates the mounting plate 2. The discharge cylinder 5 contains a second piston 7, with one side of the second piston 7... A second piston rod 9 is fixedly connected. Pulling the second piston rod 9 moves the second piston 7, which facilitates the suction of the lens nucleus and cortex into the discharge tube 5. The second piston rod 9 passes through the mounting plate 2. The infusion tube 11 passes through the mounting tube 1 and the support rod 10. The discharge tube 12 passes through the mounting tube 1 and the support rod 10. The upper surface of the adjusting head 15 has an infusion port 16, which is connected to the infusion tube 11. The lower surface of the adjusting head 15 has a discharge port 17, which is connected to the discharge tube 12.

[0028] Working principle: During use, the infusion cylinder 4, infusion tube 11, and infusion port 16 work together to infuse the eye with infusion fluid. Similarly, the discharge cylinder 5, in conjunction with the discharge tube 12 and discharge port 17, can remove the lens nucleus and cortex from the eye. When inserting the artificial lens, a main incision is first made at the edge of the cornea, through which the artificial lens is inserted. Then, an auxiliary incision is made for the entry and exit of surgical instruments. Using the infusion function of this tool, a transparent viscoelastic agent is injected into the anterior chamber to protect the internal structure and maintain the surgical space. A continuous, centered circular incision is made in front of the capsular bag. Using the discharge function of this tool, the cloudy lens nucleus and cortex are crushed and aspirated. Finally, the folded artificial lens is placed into the capsular bag, and the positioning head 15 of this tool is used to adjust the artificial lens to the centered position. During positioning, the adjustment rope 13 is pulled, which drives the positioning head 15 to rotate, thereby adjusting its tilt angle for easy positioning.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
