Description
Technical field
This utility model belongs to the ophthalmic medical instrument technical field, is specifically related to a kind of extractor for foreign body on cornea.
Background technology
Corneal foreign body is the common disease of ophthalmology outpatient service, and sickness rate is high in ocular injury.Therefore, rejecting corneal foreign body is the minor operation that ophthalmology often carries out, the doctor is when the picking corneal foreign body, usually adopt and under slit lamp microscope, reject foreign body with syringe needle, the weak point of this way is that the syringe needle tip is extremely sharp keen, when the picking corneal foreign body, be difficult for rejecting clean, especially when foreign body has the situation of getting rusty, repeatedly reject with syringe needle, larger to the normal cornea tissue injury around the foreign body, cause easily irregular wound surface, also might pierce through cornea and cause intraocular infection, even finally affect one's power of vision.
Summary of the invention
The purpose of this utility model is shortcoming and the deficiency that overcomes above-mentioned prior art, and a kind of extractor for foreign body on cornea is provided, and can be effectively clean rejecting corneal foreign body is avoided normal cornea tissue injury.
The technical solution of the utility model is: a kind of extractor for foreign body on cornea, it is characterized in that: formed by handle, cervical region, storing spoon, tongue shape tip, the rounded spoon of described storing spoon shape depression, tongue shape is most advanced and sophisticated for being positioned at the tooth shape structure of storing spoon front end, and described tongue shape tip and described handle are 45 ° of angles obliquely.
The tongue shape tip is the tooth shape structure, but corneal foreign bodies such as chooses, scrapes at the multiple operation, and the storing spoon can retain the foreign body of taking-up, and the most advanced and sophisticated handle of tongue shape forms 45 ° of angles obliquely, the operation that is conducive to get corneal foreign body, and sight line is not interrupted.
Advantage and the good effect that the utlity model has are: this extractor not only can corneal foreign bodies the multiple operation such as choose, scrape, have taking foreign body, curet concurrently, leave and take the function of foreign body, compared with the prior art, it is clean to have corneal foreign matter removing, easy to use, avoid the advantages such as corneal infection, and simple in structure, easy to use, bring great convenience for clinical treatment and operation process.
