Description

Technical Field

[0001] The utility model relates to the technical field of ophthalmic surgery, in particular to an ophthalmic corneal scalpel. Background Art

[0002] Corneal lesion scraping is a simple, rapid, and effective outpatient screening method for pathogens. Corneal lesion scraping examination is required for all infectious keratitis, including corneal ulcers. Gram-positive or negative bacteria can be distinguished after staining the scrapings for bacterial keratitis. When bacterial culture results are not obtained, it can be used as a reference indicator for clinical medication to avoid delaying the disease. Corneal lesion scraping examination can also be performed for Acanthamoeba keratitis. Wet mount examination of lesion tissue can observe Acanthamoeba cysts, which is an important means of diagnosing and discovering Acanthamoeba keratitis. How to improve the detection rate of corneal ulcer scrapings is a major problem facing clinicians.

[0003] Corneal ulcer scrapers are mainly used to clean the lesions and send them for examination and culture to assist in a clear diagnosis, especially when the lesions are close to normal tissues, a positive result is more likely to occur. Conventional corneal ulcer scrapers are operated with a No. 15 round blade installed on the handle. However, some lesions are small and deep, and the large blade is not very precise in operation, so some small lesions cannot be cleaned well. In addition, the length of the existing scalpel handle is not adjustable, which is inconvenient to use.
