Abstract
A woodpecker type lacrimal passage expansion drainage tube comprises a lower lacrimal duct expansion tube and a nasolacrimal duct expansion tube. A triangular lacrimal sac expansion fixing frame is fixedly connected between the lower end of the lower lacrimal duct expansion tube and the upper end of the nasolacrimal duct expansion tube, a fixing wing sheet is arranged on the outer surface of the lower lacrimal duct expansion tube, and a traction ring is arranged at the upper end of the lower lacrimal duct expansion tube. An injection hole can be further arranged on the nasolacrimal duct expansion tube. According to the woodpecker type lacrimal passage expansion drainage tube, the design is reasonable, the whole shape is similar to a woodpecker, during clinical usage, guidewire is drawn according to conventional surgical methods, and the woodpecker type lacrimal passage expansion drainage tube is slowly placed in a nasolacrimal duct, a lacrimal sac and a lower lacrimal punctum. And a chronic dacryocystitis caused by a combination of lower lactrimal canaliculus obstruction and nasolacrimal duct obstruction can be simultaneously treated. The woodpecker type lacrimal passage expansion drainage tube has the advantages that the structure is simple, the cost is low, the operation of tube placing is relatively easy, the tube is uneasy to slip, the pains of patients are relieved, the irritation to nasal mucosa is slight, the surgery time is short, the appearance is not affected, the therapeutic effect is good, and the like, and the woodpecker type lacrimal passage expansion drainage tube has practical and popularizing values.
Description
Technical field
This utility model relates to the improvement of ophtalmic treatments obstruction of lacrimal canaliculus, the employed probing of lacrimal passage tubular construction of obstruction of naso lacrimal duct, is a kind of Picus canus formula lacrimal passage expansion drainage tube specifically, belongs to medical apparatus and instruments.
Background technology
Lower lacrimal canaliculi blocks, obstruction of naso lacrimal duct is the commonly encountered diseases in the clinical ophthalmology, but the lacrimal passage expansion drainage tube function singleness that was in the past adopted during operative treatment maybe can only be useful for the treatment lower lacrimal canaliculi and block, and maybe can only be useful for the treatment obstruction of naso lacrimal duct.
Summary of the invention
The purpose of this utility model is to above-mentioned deficiency, provide a kind of simple in structure, put the pipe operation technique relatively easy, be difficult for landing, both can treat lower lacrimal canaliculi and block, can treat the Picus canus formula lacrimal passage expansion drainage tube of obstruction of naso lacrimal duct again simultaneously.
The technical scheme that realizes this utility model purpose is: this Picus canus formula lacrimal passage expansion drainage tube; By tear stains convergent divergent channel and nasolacrimal duct convergent divergent channel constitute down; Characteristics are to be fixedly connected with triangle dacryocystectasia fixed mount between infra tear stains convergent divergent channel lower end and the nasolacrimal duct convergent divergent channel upper end, and the outer surface of infra tear stains convergent divergent channel is provided with fixed tab.
For the ease of inserting, infra tear stains convergent divergent channel upper end is provided with bail.
In order further to improve therapeutic effect, also can on the nasolacrimal duct convergent divergent channel, be provided with liquid injection hole.
This utility model can be selected raw materials such as existing medical silica-gel material for use, and adopts conventional processes to make, and implements easily.
This utility model is reasonable in design, and global shape is similar to Picus canus, presses the routine operation method during clinical use and selects the suitable lacrimal probe of thickness to insert from puncta down, walks to walk to along the lacrimal passage direction and blocks or narrow positions, visits and passes to nasolacrimal duct; Insert lacrimal passage with the lacrimal probe that has a seal wire from puncta down, be inserted into the nasolacrimal duct opening part downwards and send into seal wire, seal wire is ticked the bail ligation that is provided with the following tear stains convergent divergent channel other end behind the nasal cavity.Extract lacrimal probe, the traction seal wire slowly drives in the wrong direction Picus canus formula lacrimal passage expansion drainage tube and is incorporated into nasolacrimal duct, lachrymal sac, following puncta.When pulling out following tear stains convergent divergent channel when having certain resistance from lacrimal point down, explain that leg-of-mutton dacryocystectasia fixed mount is arranged in lachrymal sac, launch in the fixed tab infra puncta of following tear stains convergent divergent channel outer surface, play fixed effect.
This utility model can be treated lower lacrimal canaliculi simultaneously and blocked the chronic dacryocystitis that the merging obstruction of naso lacrimal duct causes, operation technique is convenient, and is little to tissue injury, is difficult for landing, and the patient suffering is few, and therapeutic effect is good.Have simple in structure, cost is low, put the pipe operation technique relatively easy, be difficult for landing, patient suffering few, nasal mucosa is stimulated advantages such as little, that operating time short, do not influence outward appearance, therapeutic effect is good, have practical and popularizing value.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
Among the figure: 1 nasolacrimal duct convergent divergent channel, 2 dacryocystectasia fixed mounts, 3 times tear stains convergent divergent channels, 4 bails, 5 fixed tabs, 6 liquid injection holes.
The specific embodiment
This utility model is further described with the embodiment that provides below in conjunction with accompanying drawing.
With reference to accompanying drawing, this Picus canus formula lacrimal passage expansion drainage tube is made up of with nasolacrimal duct convergent divergent channel 1 two parts following tear stains convergent divergent channel 3, is fixedly connected with triangle dacryocystectasia fixed mount 2 between infra tear stains convergent divergent channel lower end and the nasolacrimal duct convergent divergent channel upper end.The outer surface of infra tear stains convergent divergent channel is provided with several fixed tabs 5, and infra tear stains convergent divergent channel upper end is fixedly connected with bail 4.On the nasolacrimal duct convergent divergent channel, have oval-shaped liquid injection hole 6.
Claims (3)
1. a Picus canus formula lacrimal passage is expanded drainage tube; By tear stains convergent divergent channel and nasolacrimal duct convergent divergent channel constitute down; It is characterized in that: be fixedly connected with triangle dacryocystectasia fixed mount between infra tear stains convergent divergent channel lower end and the nasolacrimal duct convergent divergent channel upper end, the outer surface of infra tear stains convergent divergent channel is provided with fixed tab.
