Abstract

A retention support tube for a lacrimal passage comprises a hollow base (1) and is characterized in that the support tube further comprises a tubule support body (2), wherein the front end of the tubule support body is sealed, and the rear end of the tubule support body is opened and communicated with the hollow base in a bonding way; a small hole (3) is further arranged on the side wall at the front part of the tubule support body; a doctor can keep the retention support tube for the lacrimal passage in the lacrimal passage through very simple operations; the follow-up treatment is convenient; and the treatment purpose of leading the lacrimal passage to be smooth can be achieved in a shorter time.

Description

A kind of retained type lacrimal passage stay pipe

Technical field

This utility model relates to a kind of medical apparatus and instruments.

Background technology

Obstructed lacrimal passage causes that it is a kind of common oculopathy that eye is shed tears.Treat this oculopathy with probing of lacrimal passage and extensively carry out clinical, traditional treatment is with lacrimal probe, flushing type lacrimal probe or with the heat effect of laser needle, gets through the obstructive position of lacrimal passage, to reach the unimpeded purpose of lacrimal passage.But people's lacrimal passage is not as plastics, the metallic conduit periphery central lumen that arched upward, and does not resemble the people, the animal trachea has cricoid cartilage to support yet.The animal intestines that people's lacrimal passage is seemingly cut open are the same, and are soft and bend is arranged, and inwall is pressed close to up and down, impaired like the scratch of inwall mucosa portion, or the narrow positions bacterial infection of lacrimal passage, are prone to especially cause that adhesion blocks.After visiting logical lacrimal passage with lacrimal probe, owing to block with the lacrimal passage inner wall surface of narrow positions coarsely, the case of adhesion obstruction is quite a lot of again sees for the secondary lacrimal passage.For preventing behind the probing of lacrimal passages that adhesion is blocked again; The doctor who has penetrates lacrimal passage and fixing certain hour with a rhizoid line; Though can delay like this lacrimal passage again adhesion block, the doctor will penetrate silk thread lacrimal passage and pulls out from the inferior nasal meatus outlet, operation is difficulty very; And silk thread is retained in treatments such as making follow-up flushing, antiinflammatory in the lacrimal passage for a long time and can't carries out, and also affects the treatment.

Summary of the invention

This utility model technical problem to be solved provides a kind of easy and simple to handle, successive treatment retained type lacrimal passage stay pipe easily, makes the lacrimal passage behind the sounding keep unimpeded.

A kind of retained type lacrimal passage stay pipe comprises hollow base, it is characterized in that also comprising a tubule shape supporter, and tubule shape supporter front end is airtight, and open rearward end also is communicated with hollow base bonding, aperture in addition on the anterior sidewall of tubule shape supporter.Said tubule shape supporter is processed by medical macromolecular materials or silica gel, and certain elasticity is arranged.

The method for using of this retained type lacrimal passage stay pipe is such: the probe with the size coupling is inserted in tubule shape supporter through hollow base; Probe drives the lacrimal passage stay pipe and probes into lacrimal ductule, lachrymal sac; Export until the nasolacrimal duct inferior nasal meatus; One hold hollow base then, another slow with one's hands probe that withdraws from slowly is retained in the lacrimal passage stay pipe in the lacrimal passage.Because supporter is that tubule shape and anterior sidewall have aperture; Doctor or families of patients can pour into water through hollow base at any time or anti-inflammatory medicine washes treatment; And, make apopore aim at lesions position and wash according to patient's concrete state of an illness adjustable support pipe position.The doctor uses this retained type lacrimal passage stay pipe simple to operate, and successive treatment is convenient, can reach the therapeutic purposes of unimpeded lacrimal passage within a short period of time.

The specific embodiment

Referring to Fig. 1 and Fig. 2, this utility model retained type lacrimal passage stay pipe comprises a hollow base 1 and a tubule shape supporter 2, and tubule shape supporter front end is airtight, and open rearward end also is communicated with hollow base bonding, two apertures 3 in addition on the anterior sidewall of tubule shape supporter.Said tubule shape supporter is processed by medical macromolecular materials or silica gel, and certain elasticity is arranged.Said medical macromolecular materials are PVC, TPE high-performance poly olefinic thermoplastic elastomer or polyethylene.

Claims

1. a retained type lacrimal passage stay pipe comprises hollow base (1), it is characterized in that also comprising a tubule shape supporter (2), and tubule shape supporter front end is airtight, and open rearward end also is communicated with hollow base bonding, aperture (3) in addition on the anterior sidewall of tubule shape supporter.

2. retained type lacrimal passage stay pipe according to claim 1, its characteristic also are on the anterior sidewall of said tubule shape supporter (2) two apertures (3) are arranged.
