Background

Pterygium is a common disease and frequently encountered diseases in ophthalmology, and is called pterygium in traditional Chinese medicine and commonly called fish meat. It is considered to be a chronic inflammatory disease caused by external stimuli, and is known as a single-eye or double-eye attack because it looks like an insect wing in shape. The bulbar conjunctiva and the neoplastic tissue on the cornea in the palpebral fissure part gradually increase after invading the cornea and even cover the pupillary region to seriously affect the vision. Pterygium develops from the bulbar conjunctiva and subconjunctival tissue of the palpebral fissure, becomes hypertrophic and hyperplastic, and then progresses into the cornea. In order to prevent the vision of the patient from being affected by pterygium, the best current treatment method is pterygiectomy, in which after the pterygium is cut out by operation, a healthy conjunctival graft (a membranous tissue on the surface of the eyeball) is taken from other places to cover the exposed wound surface after excision by suturing. However, the existing common method is that a doctor directly uses scissors to cut, and the defects are that the operation process is slow, regular and tidy implants are not easy to obtain manually, and the size is not easy to be controlled in a standardized way. Even if some auxiliary instruments are adopted to help doctors to take conjunctiva implants, the auxiliary equipment and the surgical equipment are still generally operated by both hands of medical staff in the operation process, the operation is inconvenient in the actual operation process, and unnecessary injuries are easily caused.
