Description

Many anti-skidding lacrimal passage pipes of ball-type

Technical field

The utility model is related to a kind of lacrimal passage pipe, more particularly to a kind of anti-skidding lacrimal passage pipe of many ball-types, belongs to treatment lacrimal passage and blocks up The ophthalmic medical instrument of plug.

Background technology

Lacrimal passage is the pipeline being located between inner eye corner and nasal cavity；From top to bottom by lacrimal point, lacrimal, tear house steward, lachrymal sac, nose Tear stains is constituted, and its function is drainage tear.If lacrimal passage because the reason such as narrow, inflammation, wound occur to block, tear drainage by Resistance, lachrymal sac then easily because tear accumulation and breed bacteria, trigger lacrimal passage disease.

Lacrimal passage disease is primarily referred to as lacrimal passage and blocked, including upper lower lacrimal canaliculi body obstruction, tear duct obstruction, nasolacrimal duct Obstruction and chronic dacryocystitis etc..Patient with such illness in eye such as is frequently accompanied by excessive tear, suppurated at the symptom；Not only affect one's power of vision, Hinder beauty, be associated with the patient of chronic dacryocystitis also while being suppurated with canthus, be a potential threat to eyes.

At present, lacrimal passage disease is generally treated using installation direct motion lacrimal passage conduit, but generally existing or because conduit is easily blocked And be unable to drainage or be difficult to because catheter surface is smooth fixed and easily come off or lack because the easy compressive deformation of hollow tubing conductor etc. is many Fall into so that intubation clinical practice is extremely restricted.Therefore, Application No. " 201520430262.1 ", entitled " positive inserted The utility model of tear duct dilating bar " discloses a kind of tear duct dilating bar for being used to treat obstruction of lacrimal passage；It by elongated real core bar, The several spherical or elliposoidal projection for being distributed in the real core bar stage casing is constituted.Although the expansion bar overcomes conventional catheters because of surface It is smooth to be difficult to the defects such as the easy compressive deformation of fixed and easy to fall off, hollow tubing conductor, but presence can not be inserted using lacrimal probe guiding Pipe, can not drainage tear, can not irrigation of lacrimal passage the drawbacks of.Therefore urgently a kind of intubation of exploitation is convenient and swift, be difficult slippage, drainage Effect is good, the on-deformable lacrimal passage pipe of tube wall.

The content of the invention

In order to overcome defect present in prior art, the utility model aims to provide that a kind of intubation is convenient and swift, be difficult Slip, drainage effect is good, the on-deformable many anti-skidding lacrimal passage pipes of ball-type of tube wall.

To achieve these goals, the utility model uses following technical scheme：It includes the body of strip；Body Two ends are closed by real core cecum, the interpositions of tube surfaces be equipped with one it is spherical or oval spherical centered on the body axis Multiple spherical or oval hemisphere juts centered on the axis, raised diameter are also distributed with intermediate projections, tube surfaces Less than the diameter of intermediate projections；Multiple rounded or oval through hole is distributed with tube surfaces.

Two real core cecums are spherical or oval spherical structure；At least respectively there is a projection both sides of intermediate projections；By At least respectively there is a through hole position of nearly two real core cecums；At least one through hole between raised and intermediate projections；Each through hole Dislocation arrangement.

Compared with the prior art, the utility model is by adopting the above-described technical solution, original positive inserted lacrimal passage is expanded Bar, inserted lachrymal catheter with blind end is opened organically to combine；Therefore can not only be multiple convex on tube wall by being distributed in Get up and expand lacrimal passage, and can also play increase friction, prevent body from slipping, and improve tube wall strength, reduce tube wall because by The effect pressed and deformed.3rd, due to employing spherical in shape or oval spherical real core cecum at body two ends, therefore both facilitate Lacrimal probe guide cannula can prevent catheter blockage again.4th, due to multiple through holes, therefore both sides is distributed with tube surfaces Just tear drainage can be dredged to irrigation of lacrimal passage again.

The utility model have the advantages that it is simple in construction, easy to operate, be difficult slip, drainage effect is good, do not damage lacrimal passage, Be conducive to popularization and application.

Brief description of the drawings

Fig. 1 is principle schematic diagram of the present utility model.

In figure：Real core cecum 1, body 2, projection 3, intermediate projections 4, through hole 5.

Embodiment

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：

As shown in Figure 1：Body 2 is strip hollow tubular structures, and its two ends is closed by real core cecum 1；The surface of body 2 Interposition is equipped with the spherical or oval spherical intermediate projections 4 centered on the body axis, and the surface of body 2 is also distributed with many The individual spherical or oval hemisphere jut 3 centered on the axis, the diameter of projection 3 is less than the diameter of intermediate projections 4；Body 2 Surface distributed has multiple rounded or oval through hole 5.

For the ease of intubation, two real core cecums 1 are both designed as spherical or oval spherical structure.

In order to increase friction, avoid body 2 from being slipped from lacrimal passage, at least respectively there is a projection 3 both sides of intermediate projections 4.

For the ease of drainage, rinse and also allow for using lacrimal probe introduction pipe body insert lacrimal passage；Close to two real cores At least respectively there is a through hole 5 position of cecum 1.

For the row's of further facilitating tear and irrigation of lacrimal passage, at least one through hole 5 between projection 3 and intermediate projections 4.

In order to avoid tube wall strength or Stiffness, each dislocation of through hole 5 arrangement.
