Abstract

The utility model discloses a punctum dilator for a flusher. The punctum dilator comprises an expanding pipeline (1), an expanding head (2) and a flusher interface (3), wherein the expanding head (2) and the flusher interface (3) are respectively connected with the two ends of the expanding pipeline (1), the front end of the expanding head (2) is provided with a blind end (4) which is in a circular-arc sealed shape, and an adjustable included angle (5) is formed at a joint between the expanding head (2) and the expanding pipeline (1). The punctum dilator for the flusher provided by the utility model has the advantages that as the certain included angle is formed between the expanding head and the expanding pipeline and is adjustable, the adjustment is performed on the included angle according to specific clinical requirements so as to be suitable for the expansion of different lacrimal puncta; as the front end of the expanding head is designed to be in the circular arc shape, the punctum dilator is ensured to not hurt a patient while the lacrimal puncta expansion is performed; and the punctum dilator is matched with the flusher, so that the flushing is completed while the lacrimal puncta expansion is performed.

Description

A kind of irrigator is used the puncta dilator

Technical field

This utility model relates to the medical instruments technical field, and particularly a kind of irrigator is used the puncta dilator.

Background technology

Though ophthalmic diseases seems minor issue, usually let the people overwhelmed with sorrow in the time of morbidity, one of modal symptom is exactly to shed tears; More common in older or old people, in treatment process, whether the lacrimal passage that often needs to adopt irrigation of lacrimal passage to judge the patient is unobstructed, and (irrigation of lacrimal passage is through liquid is injected lacrimal passage; Dredge a kind of method of its different obstructive positions, be widely used in the clinical treatment process at present), in prescription on individual diagnosis person; Often have the patient narrow and small because of the puncta of himself, cause the irrigation of lacrimal passage device to insert smoothly, need expand this moment to puncta; In the puncta process of expansion, if misoperation regular meeting causes damage to puncta, and after the puncta dilator is pulled out; Puncta is because of the elasticity Chang Ziran of autologous tissue retraction, and the irrigation of lacrimal passage device inserts and remains a difficult problem.

The utility model content

The purpose of this utility model is to solve the deficiency of prior art, provides a kind of irrigator to use the puncta dilator, and is in a certain angle between its expansion head and the expansion pipeline; And the adjustable angle of angle can be adjusted according to concrete clinical demand, is applicable to the expansion of various punctas; The Front-end Design of expansion head is in the arc-shaped; Guarantee when carrying out puncta expansion, not damage the patient, this utility model can with the supporting use of irrigator, in the expansion puncta, just can accomplish flushing simultaneously.

The purpose of this utility model realizes through following technical scheme: a kind of irrigator is used the puncta dilator; It comprises the expansion pipeline; And the expansion head and the irrigator interface that are connected to the expansion pipe ends; An expansion front end is provided with the cecum that is the circular arc closed, and the expansion head is provided with adjustable angle with expansion pipeline connecting place.

The beneficial effect of this utility model is: this utility model provides a kind of irrigator to use the puncta dilator, and is in a certain angle between its expansion head and the expansion pipeline, and the adjustable angle of angle; Can adjust according to concrete clinical demand; Be applicable to the expansion of various punctas, the Front-end Design of expansion head is in the arc-shaped, guarantees when carrying out the puncta expansion, not damage the patient; This utility model can with the supporting use of irrigator, just can accomplish flushing simultaneously in expansion in the puncta.

Description of drawings

Fig. 1 is the structural representation of this utility model;

Among the figure, 1-expands pipeline, and 2-expands head, 3-irrigator interface, 4-cecum, the adjustable angle of 5-.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is done further description, but the protection domain of this utility model is not limited to the following stated.
