Description

Technical Field

[0001] This invention relates to the field of intraocular lens technology, and more particularly to a coating treatment system for an intraocular lens folding implant head. Background Technology

[0002] Currently, intraocular lenses (IOLs) are the most effective method for correcting refractive errors in aphakic eyes. Typically, forceps are used to place the IOL into a foldable implantation tip, which is then pre-folded and implanted into the eye via an instillation device. However, current IOL foldable implantation tips are self-lubricating and uncoated, resulting in high internal surface friction. This makes it easy for the instillation rod to damage the IOL during implantation, and the foldable implantation tip can easily wear down the IOL. Furthermore, the tip can easily break during implantation, causing eye injuries, and the procedure is laborious for doctors. In addition, the coating on current IOL foldable implantation tips is an artificial coating, which has low efficiency, uneven thickness, poor consistency, and poor adhesion, failing to meet mass production requirements and posing a significant risk of substandard products entering the market. The artificial coating is also uneven, contains air bubbles, and does not significantly improve surface roughness, potentially damaging the lens during implantation. Current coating processes involve immersing the entire product in the coating. The current method of coating the outer wall of the intraocular lens (IOL) tip is problematic. During transport or use, collisions or pressure from other instruments can easily cause the coating to peel off, allowing debris to fall into the eye and hindering treatment and recovery. Furthermore, existing coating systems do not coat the semi-circular holes of the fixed and rotating flaps on the IOL tip after folding, potentially resulting in uncoated or unevenly coated areas. Additionally, the injection head of current coating systems uses a single-hole drip or injection method, which is not conducive to coating the semi-circular holes of the fixed and rotating flaps, again potentially leading to uncoated or unevenly coated areas. Therefore, there is an urgent need to develop a coating system for folded IOL tips to address these technical problems.

[0003] In view of this, the present invention is hereby proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a coating treatment system for folded intraocular lens implants, which can ensure consistent coating time, curing temperature, and coating liquid volume, uniform coating thickness, good coating consistency, and good coating adhesion. It can coat multiple folded intraocular lens implants at one time, greatly improving efficiency, and has broad application prospects, which is conducive to its widespread application.

A second moving surface 110d is provided on the outer side of the sickle-shaped folding moving slider 110. When the rotating folding petal 602 is folded, the second moving surface 110d pushes the outer side of the rotating folding petal 602 until it closes. Coating then begins. After coating is completed...The folding slider 110 continues to move forward. When the folding rotating folding flap 602 completely disengages from the folding slider 110, the folding slider 110 stops moving. The sickle-shaped inner side of the folding slider 110 has a moving surface 110c. The folding slider 110 continues to move forward. After the above movement, the folding rotating folding flap 602 rebounds due to its own elasticity.

Opening slider limiting posts 117a are provided at both ends of the folding flap opening rod 117. The opening slider limiting posts 117a are flat and are limited to the opening rod sliding groove 102f of the product hanger support column 102. The opening rod sliding groove 102f has a locking groove, so the folding flap opening rod 117 can only move linearly within the product hanger. The hanger support column 102 can move left and right, but cannot rotate or move linearly axially. The lower end of the folding flap opening slider 118 has an opening piece 118b. The opening piece 118b is flat and can be inserted into narrow gaps to fix the folding flap opening clearance groove 606 and the rotating folding flap opening clearance groove 607. After the fixed folding flap opening clearance groove 606 and the rotating folding flap opening clearance groove 607 are closed, the gap is greater than the thickness of the opening piece 118b. The opening of the guide flap is achieved by moving the folding flap opening slider 118. The upper end of the folding flap opening slider 118, parallel to the opening piece 118b, has an opening rod limiting hole 118a.

[0079] After the artificial lens implantation head 6 is installed, the product tray device 1 is placed in the waste liquid pool 204, so that the support leg 112 is inserted into the tray limiting groove 204a to prevent the product tray device 1 from moving left and right.

[0080] (2) Run

[0081] Connect the power supply to Control Panel 4 and Control Panel 1. Start servo motors 1-107, 2-202d, 3-114, 4-115, and the coating liquid supply pump. Adjust the movement of servo motor 2-202d via Control Panel 4. Stop when the injection head 302b is inserted into the insertion hole 101a. Set the distance between the product tray device 1 and the coating mechanism 30 on Control Panel 4 to ensure that the distance between the product tray device 1 and the coating mechanism 30 is consistent each time the coating is applied. After setting, start servo motor 2-202d. Servo motor 2-202d moves to the set position and stops. Servo motor 1-107 starts and begins rotating and folding the intraocular lens for insertion. Head 6, rotate counterclockwise 180° so that the tip 603 of the intraocular lens folding guide head 6 faces the bottom surface. Servo motor 107 stops. At this time, the opening piece 118b on the folding flap opening slider 118 engages with the fixed folding flap opening avoidance groove on the intraocular lens folding guide head 6. Servo motor 107 starts, and the moving surface 110d pushes the outer side of the folding and rotating folding flap 602 until the folding flap buckle 608 and the folding flap slot 609 engage, thereby closing the fixed folding flap 601 and the rotating folding flap 602.
