AI Technical Summary
Traditional ICL surgery requires filling the anterior chamber with viscoelastic material, which increases the number of surgical steps and prolongs the operation time, and may lead to complications such as acute postoperative high intraocular pressure.
An adjustment needle for ICL surgery has been designed, including an adjustment needle, an infusion handle, a flow regulator, and anti-slip grooves. The device can be disassembled through a threaded fit, which facilitates the adjustment of the infusion fluid flow and pressure, increases the friction with the ICL, and ensures accurate positioning.
It reduces the use of viscoelastic agents, simplifies surgical procedures, improves surgical precision and success rate, and avoids complications caused by viscoelastic agents.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of ophthalmic surgical instruments, specifically a positioning needle for ICL surgery. Background Technology
[0002] ICL surgery, or Implantable Collamer Lens surgery, is an advanced ophthalmic surgical method used to correct refractive errors such as myopia, hyperopia, and astigmatism. The principle of ICL surgery is to implant an artificial lens made of special materials into the eye without removing the patient's own lens. It is usually implanted in the ciliary sulcus between the iris and the natural lens. This artificial lens acts like a "super contact lens," altering the path of light refraction so that light can be accurately focused on the retina, thereby correcting vision.
[0003] Traditional methods for maintaining the anterior chamber involve filling it with viscoelastic material, which is then thoroughly cleaned after the surgery. However, this increases the number of surgical steps and prolongs the operation time. Furthermore, the viscoelastic material is not easy to clean completely, which can easily lead to postoperative complications such as acute intraocular pressure elevation.
[0004] Based on this, this utility model designs an adjustment needle for ICL surgery to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide an adjustment needle for ICL surgery to solve the problem mentioned in the background art that traditional methods of maintaining the anterior chamber require filling the anterior chamber with viscoelastic agent.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustment needle for ICL surgery, comprising an adjustment needle, an infusion handle, and a flow regulator. The adjustment needle is threadedly fitted below the infusion handle. The adjustment needle includes a connecting post and a bent needle. The bent needle is fixedly connected below the connecting post, and an adjustment block is provided at the front end of the bent needle.
[0007] Preferably, a pipe connection block is threaded onto the upper part of the infusion handle, and an infusion bottle is connected to the upper part of the pipe connection block via an infusion pipe.
[0008] Preferably, the infusion pipeline is equipped with a flow regulator.
[0009] Preferably, the outer walls of the infusion handle, connecting column, and pipe connecting block are provided with anti-slip textures.
[0010] Preferably, the area below the adjustment block is roughened.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model realizes convenient replacement and disassembly between the infusion handle, the adjusting needle and the tubing connection block through the threaded fit between the devices; it realizes the adjustment of the flow rate and pressure of the infusion fluid through the setting of the flow regulator; it realizes the increase of contact and friction with the ICL through the setting of the adjusting block; and it makes it easy for doctors to hold and prevents slipping through the anti-slip texture. Attached Figure Description
[0012] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0016] 1-Adjusting needle, 2-Infusion handle, 3-Flow regulator, 4-Connecting column, 5-Bent needle, 6-Adjusting block, 7-Pipe connection block, 8-Infusion tubing, 9-Infusion bottle. Detailed Implementation
[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figs. 1-2 This utility model provides a technical solution: an adjustment needle for ICL surgery, including an adjustment needle 1, an infusion handle 2 and a flow regulator 3. The adjustment needle 1 is threadedly fitted below the infusion handle 2. The adjustment needle 1 includes a connecting post 4 and a bent needle 5. The bent needle 5 is fixedly connected below the connecting post 4, and an adjustment block 6 is provided at the front end of the bent needle 5.
[0019] The infusion handle 2 is threaded with a pipe connection block 7, and the infusion bottle 9 is connected to the pipe connection block 7 via an infusion pipe 8.
[0020] A flow regulator 3 is installed on the infusion pipeline 8.
[0021] The outer walls of the infusion handle 2, connecting column 4 and tubing connecting block 7 are provided with anti-slip textures to facilitate doctors' grip and prevent slippage.
[0022] The area below the adjustment block 6 is roughened to increase contact and friction with the ICL.
[0023] One specific application of this embodiment is as follows: This utility model continuously infuses the eye with irrigation fluid through the infusion bottle 9 into the infusion pipeline 8, and then out through the outlet of the bent needle 5, maintaining the total amount of fluid in the anterior chamber. This allows the anterior chamber depth to be maintained without injecting viscoelastic agents, thereby reducing a series of problems caused by the use of viscoelastic agents. The flow rate and pressure of the irrigation fluid are adjusted by the flow regulator 3 on the infusion pipeline, allowing the irrigation fluid to continuously flow into the anterior chamber through the needle. The adjustment block 6 increases the contact and friction with the ICL, making it easier for the doctor to make fine adjustments to the implanted ICL during the operation, accurately positioning it in the appropriate position behind the iris and in front of the lens, improving the accuracy and success rate of the operation. The threaded fit between the devices facilitates the replacement and disassembly of the infusion handle 2, the adjustment needle 1, and the pipeline connecting block 7.
