Pressure type polishing surgical instrument for eyes

Abstract

The invention provides a pressure type polishing surgical instrument for eyes. The pressure type polishing surgical instrument comprises a handle, an adapter and a spray head pipeline, wherein a first liquid outlet is formed in the end, away from the handle, of the spray head pipeline, and the first liquid outlet is used for spraying out liquid, so that the purpose of polishing front and rear capsules through liquid spraying is achieved; and direct contact with a metallic material of a traditional polishing instrument is absent, and meanwhile, water flow with certain pressure can be used for thoroughly removing epithelial cells remained on surfaces and at corners. Therefore, in a cataract surgery process, the purpose of improving safety and effectiveness when the front and rear capsules are polished is achieved, and the situations that eye tissue is damaged and the epithelial cells are not completely removed due to a traditional metallic polisher are reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an ophthalmic pressure polishing surgical instrument. Background technique [0002] In cataract surgery, it is necessary to use the ultrasonic head to shatter the lesion, and then use the phacoemulsion handle to absorb and clean the shattered lesion tissue. After cleaning, the front and rear capsular bags of the eye are polished with metal instruments, and then implanted after polishing Crystals: Polishing with metal instruments removes residual crystal epithelial cells in the capsular bag to prevent postoperative posterior capsule opacity. [0003] At present, the polishing technology used in the market is metal equipment, and the front and rear capsules are polished by using a frosted surface at the polishing place. Due to the size limitation of the metal polisher itself during the polishing process, there will be incomplete polishing and residual cells. At the same...

Problems solved by technology

[0003] At present, the polishing technology used in the market is metal equipment, and the front and rear capsules are polished by using a frosted surface at the polishing place. Due to the size limitation of the metal polisher itself during the polishing process, there will be incomplete polishing and residual cells. At the same time During the polishing process, because the metal parts are very hard, it is easy to make mistakes in operation and damage the capsule, forcing the operation to fail and causing irreversible damage to the patient. In order to avoid damage, the doctor will be more careful in polishing, which will also affect the efficiency of the operation. Larger impact; thus lack of a polished surgical instrument for increased safety
