Embodiment Construction

[0010] Such as figure 1 As shown, a kind of ocular lacrimal duct irrigation device includes a probe and an injector, including a probe composed of a needle tube 1 and a needle handle 2. The front end of the needle tube 1 is a closed end, and its tail end is connected to the needle handle 2; On the surface of the needle tube 1, there is an expansion hose 3 coiled along its length direction. The inner surface of the expansion hose 3 is bonded to the needle tube 1. The front end of the expansion hose 3 extends close to the front end of the needle tube 1, and its rear end extends close to At the tail end of the needle tube 1, the front and rear ends of the expansion hose 3 communicate with the inner cavity of the needle tube 1 through the holes on the surface of the needle tube 1, and the surface of the expansion hose 3 has a plurality of micropores distributed along its length direction The needle tube 1 is provided with a plurality of circular holes 4 along the spiral direction ...

Abstract

An eye lacrimal duct irrigator, including a probe and an injector, including a probe composed of a needle tube and a needle handle, an expansion hose coiled on the needle tube along its length direction, the front and rear ends of the expansion hose are It communicates with the inner cavity of the needle tube, and the expansion hose is distributed with a plurality of micropores along its length; the tail end of the needle tube is connected with the injector through the needle handle. Compared with the currently used lacrimal duct probes, the present invention not only avoids secondary needle insertion, saves time and effort, is easy to operate, relieves pain of patients, and improves flushing effect.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an eye lacrimal duct flusher. Background technique [0002] Lacrimal duct blockage is a common disease in clinical ophthalmology, usually caused by blocked epiphora caused by inflammation and trauma, and pus drainage from the inner corner of the eye caused by dacryocystitis. The most common way to deal with blocked tear ducts is to unclog them. At present, the utensil for dredging the lacrimal duct is the lacrimal duct probe, which consists of a needle shaft and a needle handle. The needle shaft is a solid rod body. The disadvantage of this lacrimal duct probe is that it is time-consuming and labor-intensive, and the operation is inconvenient, which increases the pain for the patient. Contents of the invention [0003] The invention provides an eye lacrimal duct flushing device, which solves the problems of time-consuming and labor-intensive operation, inconvenient operation an...
