Description

Technical Field

[0001] The utility model relates to the technical field of intraocular lens implantation devices, in particular to an intraocular lens positioning hook with irrigation and aspiration functions. Background Art

[0002] An intraocular lens positioning hook is a tool used in ophthalmic surgeries, especially in cataract surgeries. Its main function is to assist ophthalmologists in accurately positioning and fixing the intraocular lens during implantation. In cataract surgeries, the intraocular lens is implanted into the eye to replace the non-functional natural lens. To ensure the correct position and stability of the intraocular lens, doctors use the positioning hook to adjust and fix its position.

[0003] Currently, when doctors use the intraocular lens positioning hook, they need to implant the intraocular lens with the assistance of viscoelastic agent to maintain the anterior chamber depth. After accurately adjusting the position of the intraocular lens with the positioning hook, they need to insert a suction tube to extract the viscoelastic agent. However, when extracting the viscoelastic agent, it may cause the position of the implanted intraocular lens to shift, resulting in the need to repeat the adjustment, repeatedly entering and exiting the anterior chamber, increasing the risk of intraocular infection, and affecting the postoperative vision recovery of patients.
