Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is that this utility model is without the structural representation of capillary vessel embodiment;
Fig. 2 is that this utility model is with the structural representation of a capillary vessel embodiment;
Fig. 3 is that this utility model is with the structural representation of two capillary vessel embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is only this utility model part embodiment, rather than whole embodiment.Embodiment based in this utility model, those of ordinary skills are not paying the every other embodiment obtaining under creative work prerequisite, all belong to the scope of this utility model protection.
Referring to Fig. 1, in this embodiment, lacrimal drainage tube comprises conduit 1 and bracing frame 2, and bracing frame 2 is for being inverted triangle, and on it, plane is supporting traverse, and two are tiltedly inwardly with foraminate one end tube wall to be connected with conduit 1 below, and two drift angles are arc transition.The axle center hole of conduit 1 communicates with the internal ring of bracing frame 2.In the upper end of conduit 1, be provided with two row's apertures, as shown in Figure 1, in Fig. 1, left side is the axial cutaway view of the corresponding pipeline section of conduit.The junction of conduit 1 and bracing frame 2 is provided with inclined-plane 6 transition.
When lachrymal sac pipe is inserted, by patient, utilize draught line that bracing frame 2 positions are tied up, through intranasal backward haulage to lachrymal sac, traction stop after, the bracing frame 2 being elongated and deformed restores to the original state, utilize the crossbeam of bracing frame 2 upper ends, in lachrymal sac medial wall, support, conduit 1 is fixed.After conduit 1 is fixing, along muzzle, cut off conduit 1 bottom redundance, complete the fixation procedure of conduit.Aperture 3 on the first half tube wall of conduit 1 is medicinal for flushing pus and blood and disperse, injects flushing liquor carry out focus flushing processing and impose Drug therapy by patient by medical demand from the lower end of conduit 1.After operation in patients, the inlying catheter a few days can continue to observe, treat, until reach healing.According to the improvement of clinical sign, cure, then by the lower end of intranasal clamping conduit 1, extracted gently with operating forceps by patient, be i.e. completed treatment process.
Referring to Fig. 2, this embodiment is at a side drift angle of the bracing frame 2 of Fig. 1 embodiment to connecting a capillary vessel 4, and the endoporus of this capillary vessel communicates with the internal ring of bracing frame 2.Capillary vessel tube wall is provided with two row's apertures.Capillary vessel terminal is provided with round and smooth circular head 5.On the tube wall of capillary vessel terminal inner side, there is the shrinkproof back-up ring 7 of a projection.This embodiment is for treat the patient of lachrymal sac and lower lacrimal canaliculi inflammation simultaneously.
When concrete use, capillary vessel 4 shown in Fig. 2, with draught line, in capillary tube, penetrate the internal ring of bracing frame 2, then the two lines merging knottings of turning back, by patient, through intranasal, drawn, bracing frame 2 is fixed in fossa for lacrimal sac, capillary vessel 4 imports lower lacrimal canaliculis, the termination 5 of capillary vessel 4 and shrinkproof back-up ring 7 be drawn out the mouth of pipe external after, shrinkproof back-up ring 7 is fixing by capillary vessel 4, take out draught line, carefully cut off redundance termination 5.By patient, inject flushing liquor or medicinal liquid in from conduit 1 lower end to pipe, flushing liquor or medicinal liquid be by aperture 3, and the suitable for reading and aperture 8 of conduit 1, treats lachrymal sac and lower lacrimal canaliculi.
Referring to Fig. 3, this embodiment, at the crossbeam middle part of the bracing frame 2 of Fig. 2 embodiment, is provided with another capillary vessel 9, the angle capillary vessel direction of the oblique diagram 2 of this capillary vessel, and its structure is identical with angle capillary vessel 4 with effect.This embodiment is for treat the patient of lachrymal sac and upper and lower lacrimal ductule inflammation simultaneously.
During concrete use, the capillary vessel 9 shown in diagram 3 by the illustration method of Fig. 2 embodiment, turns back through bracing frame internal ring with draught line in two capillary vessels, and wherein capillary vessel 9 imports superior canaliculus, and capillary vessel 4 imports lower lacrimal canaliculi.This Therapeutic Method can carry out cleaning down and drug treatment to lachrymal sac and upper lower lacrimal canaliculi Zone Full.
Wherein, the entire infrastructure of above-described embodiment is made by integrated silicone rubber material, and this material softness has certain elasticity, to patient's no cytotoxicity, non-stimulated, without sensitization.
