Description

A kind of Lacrimal passage indwelling tube
Technical field
The present invention relates to field of ophthalmological medical equipment, more particularly to a kind of Lacrimal passage indwelling tube.
Background technology
Lacrimal passage includes lacrimal point, lacrimal, lachrymal sac and nasolacrimal duct.Lacrimal point up and down each one, adjoins the mamillary at end in margo palpebrae On protuberance, upper lacrimal point relatively descends lacrimal point position slightly by interior, and lacrimal point displacement often causes excessive tear disease.Lacrimal for connection lacrimal point and lachrymal sac it Between tubule, point superior canaliculus and lower lacrimal canaliculi, the outside portion of each lacrimal is then almost straight first with margo palpebrae into vertical direction Angle is inwardly turned, and two lacrimals merge into tear house steward, is then opened on lachrymal sac top.Lachrymal sac is a film capsule, on the inside of eye socket In the fossa of lacrimal sac of wall front lower place, lachrymal sac upper end is closed into a speech end, about adjoins inside at the 3-5mm of top, lower end is divided a word with a hyphen at the end of a line as nasolacrimal duct. Lachrymal sac is about 1.2cm, wide 0.4-0.7cm.The muscle fibre wrapping lachrymal sac and lacrimal of orbicular muscle of eye, collapsible and expansion lachrymal sac, Tear is promoted to discharge.Nasolacrimal duct is the film pipe of connection lachrymal sac lower end, and top is embedded in bone tube chamber, bottom be tapered into Enter in nose lateral wall mucous membrane, be opened on the lateral wall of meatus nasi inferior.Tears are through upper and lower puncta, lacrimal, tear house steward, lachrymal sac, nose Tear stains flows into nasal cavity.If any position is blocked because of lesion in this lacrimal passage, a series of diseases such as excessive tear will be caused, suppurated Shape.Lacrimal passage tube operation is the hand of wound minimum in the shaping treatment of the disease such as obstruction of lacrimal passage, chronic dacryocystitis, lacrimal duct injury lacrimal passage Art type.Existing Lacrimal passage tube operation is divided into again:1st, single superior canaliculus or lower lacrimal canaliculi implantation, its shortcoming is comfortably Degree is poor, is difficult postoperative medicine lavation, voluntarily may deviate to need to put pipe again, or is retracted into lacrimal passage, haves no alternative but need row lachrymal sac to cut Open or nasal cavity removes the different Position Pipe of lacrimal passage;2nd, upper lower lacrimal canaliculi is implanted into nasal cavity ligature type simultaneously, drawbacks common be in art and During postoperative dismounting, the operation of nasal cavity is all referred to, operating difficulty is added.
The Chinese patent of Application No. 201420667638.6 discloses a kind of silica-gel lacrimal and puts pipe, including surface is smooth Silicone tube, the silica gel tube wall is provided with some liquid-leadage holes, and the silicone tube upper end is provided with the connection end for being inverted triangle, institute Connection end is stated at silicone tube upper end provided with the conduction hole connected with the central passage of silicone tube, the silicone tube connection end The traction end elongated with silica gel length of tube identical, the end ligation of the traction end are connected with one triangular apex There is draught line.The Chinese patent of Application No. 201020126933.2 discloses a kind of flexible guiding system for lacrimal duct intubation, including Conduit is constituted with stainless pin two parts with pintle, and conduit material is soft and is printed on scale above, and scale spacing is 1cm, internal diameter For 1mm, head end is blunt circle cecum band side opening;Stainless pin head end blunt circle, the pintle of cavity and upper end with flushing interface.Above-mentioned hair It is bright to realize single upper (or under) lacrimal implantation, it is required to remove by nasal cavity, so as to cause the patient one to be The discomfort or postoperative complication of row.Therefore, for comfort level during improving patient's indwelling, its laundering period is shortened, it is necessary to invent A kind of good, simple in construction, the easy to use Lacrimal passage indwelling tube of comfort level.
The content of the invention
The tear path indwelling good, easy to use there is provided a kind of comfort level it is an object of the invention to overcome drawbacks described above Pipe.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is:
A kind of Lacrimal passage indwelling tube, including body and sleeve pipe, described sleeve pipe are set on body, described sleeve pipe and body it is upper Portion is adapted, and described sleeve pipe includes casing main body and fastener, and the fastener is arranged on casing main body upper end.
Further, the body includes the changeover portion of body main body and elasticity, and the changeover portion is fixed on body main body Upper end.
Further, the changeover portion includes two support columns and fixed block, and one end of the support column is fixed on body In main body, the other end of the support column is fixed on fixed block, and the fixed block is provided with relative with the opening of body main body The through hole answered.
Further, the fastener is provided with the bayonet socket being adapted with fixed block.
Further, the fastener is adapted with the shape of the margo palpebrae cambered surface of people.
Further, the fastener includes connector and card hook part, and the connector is connected with the end of casing main body, institute State card hook part with connector to be connected, the card hook part is shaped as arc.
Further, described sleeve pipe main body and fastener are integrally formed.
Further, the external diameter of the body is 0.9-1.0mm, and the thickness of the body is 0.2-0.3mm, the body Length be 5.5-6.0cm or 2.8-3.5cm.
Further, the material of the body is PVC, and the material of described sleeve pipe is silica gel.
Further, the body is provided with scale, and the spacing of the scale is 1cm.
The beneficial effects of the present invention are:Body and sleeve pipe are used cooperatively, and body is entered in lachrymal sac by lacrimal, and is led to Cross fastener to be fixed in the margo palpebrae of people, it is to avoid situations such as Lacrimal passage indwelling tube is voluntarily deviate from or is retracted into lacrimal passage occurs, improve simultaneously Lacrimal passage indwelling tube comfort level during patient's indwelling, shortens its laundering period;It is direct that lacrimal passage plants the postoperative Lacrimal passage indwelling tube of pipe indwelling Pulled out at lacrimal point up and down, without being pulled out by nasal, remove convenient, it is simple and easy to do, while avoiding clinical complications; The present invention is simple in construction, and manufacture craft is simple, it is easy to produce.
