AI Technical Summary
In current iris root transection surgery, the needle exit point depends on the doctor's clinical experience, which increases the operation time and the risk of eye damage, and is especially difficult for young doctors.
A suture needle for iris root transection was designed, including a handle and a hook. The end of the hook has a tapered needle tip and a recessed hook groove. In conjunction with an iris pressure device and a puncture positioning device, the suture is directly inserted from the puncture point through the hook, reducing trial and error and eye damage. The iris root transection repair is performed using a step-sewing machine-style suture method.
This improved the practicality of iris root transection suture needles, reduced surgical time and the risk of eye damage, simplified the operation process, and improved the accuracy and efficiency of the surgery.

TECHNICAL FIELD
[0001] The utility model relates to suture needle technical field, specifically, it relates to a iris root disconnection suture needle. BACKGROUND
[0002] Iris root disconnection refers to the rupture of the connection between iris and ciliary body, and the tissue at the connection is the weakest and is easy to rupture under external force. When the external force acts on the eyeball from the front, the pupil is blocked, the peripheral sclera is expanded, and the aqueous humor retained in the anterior chamber impacts the peripheral iris without lens support. The blunt force not only causes direct damage at the impact site, but also transmits in the eye due to the incompressible spherical shape of the eyeball, resulting in traumatic iris root disconnection. Currently, the surgical treatment of iris root disconnection is basically from the inside of the eye to the outside of the sclera through the iris root. The position of the exit point depends on the clinical experience of the doctor. For young doctors, it may need to be operated several times to exit at the appropriate position, increasing the operation time and damage to the eye. Therefore, we propose a iris root disconnection suture needle. SUMMARY
