Description

Technical Field

[0001] The utility model belongs to the technical field of ophthalmic surgical instruments, and in particular relates to a multifunctional corneal foreign body remover. Background Art

[0002] Corneal foreign bodies are a common ocular injury seen in outpatient and emergency ophthalmology departments, often causing significant irritation such as redness, photophobia, and tearing, requiring prompt treatment. Metallic foreign bodies, the most common type of corneal foreign body, pose significant risks. If left untreated, they can cause the spread of metal ions, leading to ferruginous or copper-corrosion conditions. In severe cases, corneal ulcers and even perforations can occur, leading to blindness. Clinically, corneal foreign bodies and rust rings are often removed using syringe needles. However, because needles cannot grasp foreign bodies, they can only be "shoveled" at them, potentially causing them to slide across the corneal surface or even penetrate deep into the conjunctival sac, causing secondary damage. This inconvenience is particularly pronounced when metallic foreign bodies undergo oxidation, becoming brittle and breaking into small pieces. Furthermore, because syringe needles have sharp tips and a small surface area, scraping away rust rings with the tip is difficult to achieve quickly and easily. Furthermore, sudden eye movements caused by nervousness can sometimes lead to serious consequences such as corneal perforation.

[0003] Therefore, it is necessary to design a multifunctional corneal foreign body remover to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a multifunctional corneal foreign body remover to solve the above problems, thereby improving the convenience and safety of corneal foreign body removal and facilitating the scraping of rust rings.
