Description
Technical field
This utility model relates to field of ophthalmological medical equipment, particularly a kind of for dredge nasolacrimal duct, obstruction of lacrimal canaliculus, puncta obturation silica-gel lacrimal put pipe.
Background technology
Tear flow into nasal cavity through upper and lower puncta, lacrimal ductule, tear house steward, lachrymal sac, nasolacrimal duct.If arbitrary position is blocked because of pathological changes in this lacrimal passage, the series of symptoms such as will cause excessive tear, suppurate.Need to treat in time.The main dacryocystorhinostomy that adopts combines tear stains tube placing operation or lacrimal passage drainage tubes implantation etc. at present.Need along the reverse Lacrimal passage tube of inserting for supporting nasolacrimal duct or lower lacrimal canaliculi of nasolacrimal duct in operation, this Lacrimal passage tube end has a traction end for drawing, from nasolacrimal duct lower end, Lacrimal passage tube is upwards pulled out lower puncta by draught line in operation, then draught line is removed, and traction end because of with the silica gel tube of lachrymal sac, nasolacrimal duct be one be connected, also to stay among lacrimal ductule, after the 1-3 month, take out the object reaching dredging nasolacrimal duct.There are the following problems for the Lacrimal passage tube adopted in this kind of operation: 1, this traction end end often easily rubs patient cornea, conjunctiva, and causes a series of discomfort of patient or postoperative complication.2, superior canaliculus obstruction can not be treated, puncta is inaccessible.
Utility model content
The above-mentioned defect that this utility model exists for Lacrimal passage tube of the prior art, provides a kind of and reduces the silica-gel lacrimal that corrective surgery do not accommodate complication and put pipe, and effectively to treat, associating superior canaliculus blocks, puncta is inaccessible and improve the curative effect of operation.
The purpose of this utility model realizes like this, a kind of silica-gel lacrimal puts pipe, comprise ganoid silica gel tube, described silica gel tube tube wall is provided with some liquid-leadage holes, described silica gel tube upper end is provided with in being inverted leg-of-mutton link, described link is provided with the conduction hole be communicated with the central passage of silica gel tube near silica gel tube upper end, a triangular apex place of described silica gel tube link is connected with the elongated traction end identical with silica gel tube length, and the end ligation of described traction end has draught line.
Silica-gel lacrimal of the present utility model puts pipe, because being provided with an elongated traction end equal with silica gel tube length, carry out Lacrimal passage tube perform the operation into time, silica gel tube passes through the reverse introducing lacrimal passage of traction end from nasolacrimal duct lower end, make the link of del terminate in lachrymal sac place and can be used for support lachrymal sac, elongated traction end again through upper puncta, lacrimal ductule, lachrymal sac, nasolacrimal duct to nasal cavity.Then injecting medicinal liquid from glue silicone tube lower end carries out follow-up, the processes such as flushing.Therefore, the beneficial effect that silica-gel lacrimal of the present utility model puts pipe is, after silica gel tube traction is inserted nasolacrimal duct, lachrymal sac, lower lacrimal canaliculi by traction end, nasolacrimal duct lower end is turned back to again through upper puncta, superior canaliculus, lachrymal sac, corneal, conjunctiva can not cause friction or damage, reduce the generation of the inadaptable of patient and complication; And superior canaliculus obstruction, puncta obturation can be treated.And, when the liquid-leadage hole that the silica gel tube tube wall of hollow is arranged can inject medicinal liquid from silica gel tube end in pipe, medicinal liquid is flowed out by liquid-leadage hole, nasolacrimal duct passage around silica gel wall outer wall is rinsed and antiinflammatory, the inner chamber of silica gel tube and being communicated with of top conduction hole, the medicinal liquid in silica gel tube can be made to flow out from conduction hole, to rinse and antiinflammatory lachrymal sac and surrounding.
As improvement of the present utility model, described traction end and silica gel tube are the obtuse angle of 90 °-135 °.
Improve as of the present utility model another, the external diameter of described silica gel tube is 3-4mm, and the external diameter of traction end is 1-1.5mm.
When drawing for preventing operation, break traction end, described link is provided with a through wires hole near traction end place, and described draught line is two strands of doubling, first passes from through wires hole with before the ligation of traction end end.
Accompanying drawing explanation
Fig. 1 is the structural representation that silica-gel lacrimal of the present utility model puts pipe.
Wherein, 1 silica gel tube, 1A liquid-leadage hole, 2 links, 3 traction ends; 4 draught lines; 5 conduction holes, 6 through wires holes.
Detailed description of the invention
As shown in Figure 1, for silica-gel lacrimal of the present utility model puts pipe, comprise ganoid silica gel tube 1, silica gel tube 1 tube wall is provided with some liquid-leadage hole 1A, silica gel tube 1 upper end is provided with in being inverted leg-of-mutton link 2, link 2 is provided with the conduction hole 5 be communicated with the central passage of silica gel tube 1 near silica gel tube 1 upper end, a triangular apex place of silica gel tube link 2 is connected with the elongated traction end 3 identical with silica gel tube 1 length, and the end ligation of traction end 3 has draught line 4.Wherein, traction end 3 and the obtuse angle of silica gel tube 1 in 90 °-135 °, the external diameter of silica gel tube 1 is 3-4mm, and traction end 3 is external diameter 1-1.5mm solid silicon colloid; Because traction end 3 is comparatively thin, when drawing for preventing operation, break traction end 3, link 2 is provided with a through wires hole 6 near traction end 3 place, during ligation draught line 4, is first two strands by its doubling, and wear from through wires hole and walk around, then by draught line and the ligation of traction end end, and two bursts of merging.
Adopt silica-gel lacrimal of the present utility model put pipe carry out Lacrimal passage tube operation time, silica gel tube 1 passes through the reverse introducing nasolacrimal duct of traction end 3 from nasolacrimal duct lower end, make the link 2 of del terminate in lachrymal sac place and can be used for supporting lachrymal sac, elongated traction end 3 goes out lower puncta, turns back to nasolacrimal duct lower end through upper puncta, superior canaliculus, lachrymal sac from nasolacrimal duct upper end again, then inject medicinal liquid from glue silicone tube 1 lower end and carry out follow-up logical medicinal liquid, the processes such as flushing.Therefore, silica-gel lacrimal of the present utility model puts pipe, after silica gel tube 1 traction is inserted nasolacrimal duct by traction end 3, go out lower puncta, turn back to again nasolacrimal duct lower end through upper puncta, superior canaliculus, lachrymal sac again, to causing friction or damage near eyeball, the generation of the inadaptable of patient and complication can not be reduced; And superior canaliculus obstruction, puncta obturation can be treated.And, when the liquid-leadage hole that silica gel tube 1 tube wall of hollow is arranged can inject medicinal liquid from silica gel tube end in pipe, medicinal liquid is flowed out by liquid-leadage hole 1A, nasolacrimal duct passage around silica gel tube outer wall is rinsed and antiinflammatory, the bore passages of silica gel tube 1 and being communicated with of top conduction hole, the medicinal liquid in silica gel tube 1 can be made to flow out from conduction hole 5, to rinse and antiinflammatory lachrymal sac and surrounding position.
