Conjunctival sac drainage aqueous humor micro-irrigation device for treating dry eye lesion

Abstract

The invention relates to the technical field of medical instruments, and particularly discloses a conjunctival sac drainage aqueous humor micro-irrigation device for treating dry eye lesion. The device comprises a drainage intubation tube, a compression soft body, a drainage body, a drainage catheter and a liquid outlet body which are connected in sequence, and the drainage intubation tube, the compression soft body, the drainage body, the drainage catheter and the liquid outlet body are connected in sequence. The front end of the drainage intubation tube is provided with a tip end which can be conveniently inserted into the anterior chamber, and the middle section of the drainage cannula is provided with an anti-backflow assembly; in the drainage irrigation process, sterile aqueous humor is drained to the eye surface to achieve the wetting effect, the effect is better than that of conventional manual operation, carrying is not needed, meanwhile, the problem that drainage irrigation cannot be conducted after an existing aqueous humor drainage device is blocked is effectively solved, the structural design is simple, and the using effect is excellent; in addition, the insertion process of the drainage cannula can be accurately and accurately carried out through the inserted guide wire, and the use effect is excellent.

Description

technical field [0001] The invention relates to the technical field of medical devices, and specifically discloses a conjunctival sac drainage aqueous humor micro-irrigation device for treating dry eye lesions. Background technique [0002] Dry eye disease is a general term for a series of ocular surface diseases caused by abnormal tear quality, quantity and dynamics caused by various reasons, leading to the destruction of tear film function. There are two types of causes, insufficient tear secretion and excessive tear evaporation. Clinical manifestations include eye fatigue, dry eyes, foreign body sensation in the eyes, eye pain, photophobia, tearing, etc. Due to the current popularization of computers and smart phones, the number of people suffering from this disease is increasing. [0003] Currently, non-drug treatment strategies for dry eye clinically mainly include three options. First, physical therapy such as massage and hot compresses for the eyes; second, increas...

AI Technical Summary

Problems solved by technology

The surgical method in which the device disclosed in the invention is implanted in the conjunctival sac of the ocular surface is feasible, and the sterile aqueous humor can be drained to the ocular surface under reasonable automatic control to play a moisturizing role, no need to carry, manual use, and the aqueous humor Clean and sterile, short cycle time, sufficient sources, but because the irrigation port on the diversion body is easily blocked during actual use, the aqueous humor after drainage cannot flow out from the irrigation port to wet the surface of the eyeball

In addition, since the first drainage tube is not easy to find the corresponding puncture point in the process of implanting the anterior chamber, it can be implanted accurately and quickly, resulting in cumbersome and difficult steps in the entire operation process.
