Daily life.
Existing common therapeutic modality is lacrimal passage intubation art, traditional intubation way are as follows: from upper and lower puncta inserting needle, in tear
It is placed in a U-shaped medical very thin transparent silicon sebific duct (such as: Crawford pipe) in road, keeps different lacrimal passages unimpeded, silicone tube
Both ends are drawn in nasal cavity, and it is stitched a wire loop at the wing of nose and is fixed, when doctor determines tube drawing according to patient's different situations
Between (after lacrimal passage pipe mucous membrane recovery after can be taken off).This lacrimal passage pipe also blocks while supporting lacrimal passage during merging
Lacrimal passage, no matter and obstruction of lacrimal passage position wherein, lacrimal passage pipe is both needed to merging nasolacrimal duct, for the trouble of simple superior lacrimal passage obstruction
Person is easy to cause nasolacrimal duct unnecessary damage, causes infection.
Utility model content
In view of the deficiencies of the prior art, the utility model provide it is a kind of merging drainage tube is carried out according to block part, by tear
Road does not influence to arrange the dewatering type lacrimal passage pipe of tear while support.
The technical scheme adopted by the utility model to solve the technical problem is as follows: the dewatering type lacrimal passage pipe includes hollow
Lacrimal passage drainage tubes and the metal probe that lacrimal passage drainage tubes can be interspersed in, the top of the lacrimal passage drainage tubes be equipped with it is connected to it,
Sucker with circular hole identical with its internal diameter, the metal probe are inserted into lacrimal passage drainage tubes, the metal by the circular hole of sucker
Adjustable plate is additionally provided on probe, the adjustable plate is movably arranged on metal probe.
In a kind of preferred embodiment of dewatering type lacrimal passage pipe provided by the utility model, the lacrimal passage drainage tubes are equipped with 2
Root can be respectively used to superior canaliculus and lower lacrimal canaliculi.
In a kind of preferred embodiment of dewatering type lacrimal passage pipe provided by the utility model, the adjustable plate uses clamp screw
Nail is fixed on metal probe.
In a kind of preferred embodiment of dewatering type lacrimal passage pipe provided by the utility model, the lacrimal passage drainage tubes use silicon
Sebific duct.
The length of the lacrimal passage drainage tubes is merging lacrimal or merging lachrymal sac or merging nasolacrimal duct.
In a kind of preferred embodiment of dewatering type lacrimal passage pipe provided by the utility model, the sucker uses PHEMA material
Material is made.
In a kind of preferred embodiment of dewatering type lacrimal passage pipe provided by the utility model, the sucker is inhaled using ellipse
Disk, edge is towards lacrimal passage drainage tubes side, for being adsorbed at puncta.
In a kind of preferred embodiment of dewatering type lacrimal passage pipe provided by the utility model, the adjustable plate using round or
Rectangular adjustable plate, when using circular adjusting plate, diameter is less than the long axis of oval sucker, when using rectangular adjustable plate,
Length is less than the long axis of oval sucker, and width is less than the short axle of oval sucker.
Compared with prior art, the beneficial effect of dewatering type lacrimal passage pipe provided by the utility model is: the utility model will
Metal probe is inserted into lacrimal passage drainage tubes, selects the length of lacrimal passage drainage tubes (to be only placed in lacrimal or only according to the position of blocking
Merging lachrymal sac is only placed in nasolacrimal duct), it is placed in from puncta by lacrimal passage drainage tubes, it will after metal probe is by block part pass blocking
Metal probe takes out, using the sucker suction on lacrimal passage drainage tubes on puncta, since the both ends of lacrimal passage drainage tubes are opening,
So that tear is smoothly discharged, has achieved the purpose that not influence to arrange tear while supporting lacrimal passage, meanwhile, for upper lacrimal passage resistance merely
The patient of plug, lacrimal passage drainage tubes without pass through nasolacrimal duct from drawing in nasal cavity, it is unnecessary so as to avoid being caused to nasolacrimal duct
Damage.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is the structural schematic diagram of one preferred embodiment of dewatering type lacrimal passage pipe provided by the utility model；
Fig. 2 is the partial sectional view at the I that Fig. 1 is provided；
Fig. 3 is the implementation state diagram of one preferred embodiment of dewatering type lacrimal passage pipe provided by the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
All other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the dewatering type lacrimal passage pipe includes hollow lacrimal passage drainage tubes 11 and can be interspersed in lacrimal passage drainage tubes
Metal probe 12, the tops of the lacrimal passage drainage tubes 11 is equipped with suction connected to it, with circular hole identical with its internal diameter
