The injection tube 4 is disposed at the front end of the lens chamber 3, and a second suture groove 41 for accommodating the intraocular lens suture is provided within the injection tube 4. The second suture groove 41 is connected to the first suture groove 7. Specifically... When the artificial lens is placed in the inner cavity 6 and curled into an elliptical shape, its sutures will enter the first suture groove 7. During the injection process, the sutures move sequentially within the first suture groove 7 and the second suture groove 41, which can prevent the sutures from rubbing against the side wall of the inner cavity 6 and the inside of the injection tube 4, thus improving the surgical effect and safety. The automatic injection device 5 is located at the tail end of the injector body 1. The automatic injection device 5 is connected to the push rod 2 to drive the push rod 2 to move within the injection tube 11 to implant the artificial lens into the surgical site, thereby achieving precise control of the injection speed and force, avoiding the artificial lens being pushed out too fast or too slow, and reducing surgical risks.
