Abstract
The invention relates to an ophthalmology full lacrimal passage backstop which supports the lacrimal passage after damaged and blocking dredge, leads a die sticking to ventilate and leads drugs to filter in the lacrimal passage. The invention has the advantages of hard recrudesce after healing and low cost. A round tube lacrimal duct backstop, a dacryocyst backstop and a lacrimonasal duct backstop are made as a whole body by silica gel. The lacrimal duct backstop is in an angle of 90 degrees with the dacryocyst backstop and the lacrimonasal duct backstop; two incarcerated claws are arranged at the outer side of the combined location of the tube walls of the dacryocyst backstop and the lacrimonasal duct backstop; the tube walls are provided with drug leakage ventilating holes and finally the two drug leakage ventilating holes are penetrated with a lower draft line symmetrically. A draft shaft is arranged in the dacryocyst backstop and an upper draft line pulls the draft shaft. Two thrums are combined and tied at the external end of an opening of the lacrimal duct backstop and are stuck together with an external opening of the lacrimal duct backstop. In all the backstops used for curing the damaged lacrimal passage, springs are added in the tubes of the the dacryocyst backstop and the lacrimonasal duct backstop to prevent the damaged lacrimal passage to squeeze the backstops during the concrescence process.
Description
Technical field the present invention relates to a kind of ophthalmology complete lacrimal passage underprop.
Background technology excessive tear disease clinically is the passage of drain tear---obstructed lacrimal passage causes that its Therapeutic Method has: and irrigation of lacrimal passage, lacrimal passage laser mediation lacrimal passage, lacrimal passage is put pipe dacryocystorhinostomy etc.Existing obstructed lacrimal passage clinically has the hot injury with the mediation of lacrimal passage laser, to the obstruction of naso lacrimal duct weak effect, blocks easily recurrence, and the equipment heaviness costs an arm and a leg.Lacrimal passage is put the pipe dacryocystorhinostomy can only treat obstruction of lacrimal canaliculus, and hemorrhage many, stays cicatrix.
Summary of the invention is cured defect of insufficient in order to overcome existing obstructed lacrimal passage, the present invention's purpose is, a kind of complete lacrimal passage underprop is provided, support damage, block the lacrimal passage after dredging, make the ventilative and medicine infiltration lacrimal passage of mucosa, be difficult for recurrence after the rehabilitation, expense is low, is beneficial to the popularization and application of all kinds of hospitals and community, rural health institute to lacrimal passage damage, obstruction medical skill.The technical solution adopted for the present invention to solve the technical problems is: be made into pipe shape lacrimal ductule supporter, lachrymal sac supporter, tear nasal tube supporter in one with silica gel, lacrimal ductule supporter and lachrymal sac supporter, tear nasal tube supporter are 90 °, two incarceration pawls are established in the lachrymal sac supporter and the outside, tear nasal tube supporter tube wall junction, have on the tube wall and ooze the medicine air-vent, latter two oozes medicine air-vent symmetry and is installed with down draught line.The built-in axis of traction of lachrymal sac supporter, last draught line draws axis of traction, merges knotting at lacrimal ductule supporter mouth outer end two the end of a thread and is sticked together with lacrimal ductule supporter collar extension.In being used for the treatment of the employed supporter of damage lacrimal passage, be added with spring in the pipe of lachrymal sac supporter, tear nasal tube supporter part, prevent to damage lacrimal passage and in agglutination, push supporter.After patient's anesthesia, the doctor penetrates lacrimal probe to backguy, enters from puncta, draw nasal cavity by lacrimal passage, backguy connects goes up draught line, draws supporter slowly to enter lacrimal passage, after treating lacrimal passage rehabilitation typing, following draught line pulls out supporter from lacrimal passage, finish the lacrimal passage therapeutic process.
The invention has the beneficial effects as follows, support lacrimal passage, be convenient to the lacrimal passage injectable drug, be difficult for recurrence after the rehabilitation, expense is low.
The present invention is further described below in conjunction with drawings and Examples for description of drawings.
Fig. 1 is an embodiment of the invention profile.
Fig. 2 is Fig. 1 profile.
1. lacrimal ductule supporters among the figure, 2. lachrymal sac supporter, 3. tear nasal tube supporter, 4. axis of traction is 5. gone up draught line, and 6. the incarceration pawl 7. oozes the medicine air-vent, 8. descends draught line.
The specific embodiment elaborates to the specific embodiment of the present invention below in conjunction with accompanying drawing.
Technical scheme requires: be made into pipe shape lacrimal ductule supporter, lachrymal sac supporter, tear nasal tube supporter in one with silica gel, lacrimal ductule supporter and lachrymal sac supporter, tear nasal tube supporter are 90 °, two incarceration pawls are established in the lachrymal sac supporter and the outside, tear nasal tube supporter tube wall junction, have on the tube wall and ooze the medicine air-vent, latter two oozes medicine air-vent symmetry and is installed with down draught line.The built-in axis of traction of lachrymal sac supporter, last draught line draws axis of traction, merges knotting at lacrimal ductule supporter mouth outer end two the end of a thread and is sticked together with lacrimal ductule supporter collar extension.In being used for the treatment of the employed supporter of damage lacrimal passage, be added with spring in the pipe of lachrymal sac supporter, tear nasal tube supporter part, prevent to damage lacrimal passage and in agglutination, push supporter.
According to the technical scheme requirement, the specific embodiment is as follows:
In Fig. 2, be made into pipe shape lacrimal ductule supporter (1) with silica gel, lachrymal sac supporter (2), tear nasal tube supporter (3) is in one, lacrimal ductule supporter (1) and lachrymal sac supporter (2), tear nasal tube supporter (3) is 90 °, two incarceration pawls (6) are established in the lachrymal sac supporter (2) and the outside, tear nasal tube supporter (3) tube wall junction, have on the tube wall and ooze medicine air-vent (7), latter two oozes medicine air-vent (7) symmetry and is installed with down draught line (8), the built-in axis of traction of lachrymal sac supporter (2) (4), last draught line (5) draws axis of traction (4), merges knotting at lacrimal ductule supporter (1) mouthful outer end two the end of a thread and is sticked together with lacrimal ductule supporter (1) collar extension.In being used for the treatment of the employed supporter of damage lacrimal passage, be added with spring in the pipe of lachrymal sac supporter, tear nasal tube supporter part.
The present invention has filled up lacrimal ductule, lachrymal sac and the damage of tear nasal tube, has blocked the defective of treatment, is beneficial to medical technique level and improves.
