Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of ophthalmic surgery, in particular to a XEN tube resetting device and a manufacturing method thereof. Background Art
[0002] Glaucoma, the world's leading irreversible blinding eye disease, poses a serious threat to patients' vision due to its high blindness rate and irreversible characteristics. Traditionally, open-angle glaucoma is mainly treated with trabeculectomy, but this surgical method is not only traumatic, requiring an 8mm conjunctival incision, but also has frequent postoperative complications, affecting patients' recovery and quality of life.
[0003] In order to overcome these challenges, a variety of minimally invasive anti-glaucoma surgical techniques have been gradually and successfully introduced and implemented, such as ExPress drainage pin implantation, ultrasonic cycloplasty, internal canalicular dilation, carbon dioxide laser-assisted deep sclerectomy, 3D canalicular dilation, penetrating canalicular dilation, and KDB double-edged internal trabeculotomy, etc. These minimally invasive surgical methods not only significantly reduce intraocular pressure and achieve good treatment effects, but also greatly reduce postoperative complications and improve patients' postoperative quality of life.
[0004] However, we did not stop there. In order to further realize the design of individualized surgical plans for glaucoma patients and create a new way of minimally invasive subconjunctival drainage surgery, the minimally invasive implantation of glaucoma drainage tubes (XEN tubes) is currently being implemented. This surgical method has brought new hope for the treatment of glaucoma patients with its less trauma, lower risk of complications and higher surgical success rate.
[0005] However, with the popularity of XEN tube implantation, some patients have clinical symptoms of XEN tube displacement. Therefore, it is necessary to perform a repositioning operation on the XEN tube. In traditional repositioning operations, doctors rely on personal experience and skills to reposition the XEN tube manually. However, this process is extremely challenging because doctors not only need to accurately judge the horizontal position of the XEN tube, but also need to finely control its depth to maximize the drainage effect and avoid damage to surrounding tissues. The limitation of the traditional repositioning method is that it is highly dependent on the doctor's personal skills and experience, which may lead to uncertainty in the repositioning results. There may also be risks of increased operational difficulty and misjudgment.
[0006] Therefore, those skilled in the art have proposed a XEN tube resetting device and a manufacturing method thereof to solve the problems raised in the background art. Summary of the invention
[0007] In order to solve the above technical problems, the present invention provides a XEN tube resetting device and a manufacturing method thereof to solve the problems in the background technology.

[0031] refer to Figures 1 to 4 The present invention provides a XEN tube resetting device, comprising a puncture needle 1, a resetting member 2 and forceps 3. The puncture needle 1 has a needle head of 23G and is used to puncture the conjunctiva of the eye to create a tunnel.
[0032] The resetting member 2 comprises a guide member 21 , a hose 23 is provided at the front end of the guide member 21 , a track 24 is provided at the front end of the hose 23 , and the length of the track 24 is one third of the length of the hose 23 , wherein the guide member 21 includes but is not limited to an indwelling needle.
[0033] The guide member 21 is provided with a needle holding handle 22 at the rear end, wherein the needle holding handle 22 is fixedly connected to the front end with a needle, and the needle is placed inside the guide member 21 and the hose 23 . The guide member 21 is provided with a protective cover 25 at the front end, and the hose 23 is arranged inside the protective cover 25 .
[0034] As can be seen from the above, when using the device, the doctor first pulls out the needle through the needle handle 22 and removes the protective cover 25 at the front end of the guide 21. Then, the doctor uses corneal scleral scissors to open a track 24 at the front end of the hose 23. After completing this step, the XEN tube is placed inside the opened track 24.
[0035] Next, the doctor uses the puncture needle 1 to puncture the conjunctiva of the patient's eye to create a tunnel. After that, the doctor inserts a portion of the track 24 into the tunnel. To ensure that the XEN tube is properly repositioned, the doctor uses forceps 3 to push the XEN tube into the tunnel until it is fully repositioned.
[0036] The XEN tube resetting device performs surgical operations through tiny punctures and tunnels, significantly reducing surgical trauma. This not only helps to reduce the patient's postoperative pain and discomfort, but also promotes rapid recovery. The use of the device reduces the risk during surgery. Secondly, the resetting device is relatively simple and fast in the process of resetting the XEN tube, and can accurately control the placement and depth of the XEN tube. The doctor can quickly complete the resetting of the XEN tube, which helps to improve the efficiency of the operation. Finally, the XEN tube resetting device has a simple structure, reasonable design, clear functions, convenient material acquisition and easy operation, providing an efficient, safe and economical surgical treatment option for XEN tube resetting.
