Eyeball cleaning mechanism for ophthalmologic cataract resection surgery

Abstract

The invention discloses an eyeball cleaning mechanism for ophthalmology department cataract resection surgery, and relates to the technical field of medicine, the eyeball cleaning mechanism comprises a spray pipe, the right side of the spray pipe is fixedly connected with a water spray head, and the spray pipe is internally provided with a water pressure detection automatic closing mechanism. By arranging a water pressure detection automatic closing mechanism, once injection pressure in the spray pipe is abnormal and the pressure is excessively large instantly, a shifting plate and a rotating rod are instantly pushed to rotate at a high speed, the frequency of vertical vibration of a pushing block is increased, air instantly fills the opening and closing cavity through an air groove, and the speed of air entering the opening and closing cavity is larger than the flowing speed of small-diameter air grooves; and the two opening and closing plates instantly close a channel in the spraying pipe, so that a response can be made immediately, high-strength out-of-control spraying of water flow is reminded in time, the water flow is reduced, medical staff have enough time to respond and move away, and eye health of a patient is ensured.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to an eyeball cleaning mechanism for ophthalmic cataractectomy. Background technique [0002] All kinds of reasons, such as aging, genetics, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., can cause lens metabolic disorders, resulting in lens protein denaturation and opacity, called cataract. At this time, the light is clouded by the lens. The obstruction cannot be projected on the retina, resulting in blurred vision. It is more common in people over the age of 40, and the incidence increases with age. At present, the patient's eyeball needs to be cleaned before cataract resection. However, the water pressure of the current cleaning nozzle is usually controlled by doctors and instruments. Once the operation is wrong and the excessive water pressure directly hits the patient's eye, it cannot be controlled and rescued in time. , ...
