Abstract
A modified lacrimal drainage tube includes a vessel and a support bracket, the bottom end of the support bracket connected with one end of the vessel, the axis hole of the vessel communicated with the inner side of the support bracket; a plurality of holes are arranged on the wall at the upper part of the vessel, the support bracket having a circular structure, the lower part of the support bracket being U-shaped, the upper end of the vessel vertically connected with the U-shaped bottom end of the support bracket. An inclined surface is positioned on either side of the upper end of the vessel. The support bracket recovers with the help of its own elasticity after leading in the lacrimal sac, capable of fully washing and dosing to areas supported by the support bracket and areas with holes at the upper part of the vessel through the vessel, which has very good healing effect, the inclined surface at the upper part of the vessel making smooth to lead in; the U-shaped structure of the support bracket may optimize the productive technique and ensure the product quality. The capillary vessel can heal the canaliculus.
Description
Technical field
This utility model relates to the ophthalmic medical utensil, particularly a kind of lachrymal sac drainage tube.The patient who is used for the treatment of inflammation of lachrymal sac road and lacrimal ductule inflammation.
Background technology
Ophthalmic patient is shed tears incessantly because of lachrymal sac road inflammation regular meeting, and is agonizing.Traditional clinical treatment method is to wash and administration in metal tube, chicken or drake feather pipe or the plastic tube intubate importing lachrymal sac.Its shortcoming is that these utensils are irregular, and therapeutic effect is bad, and brings bigger misery to patient, is full of medical-risk.In order to address the above problem, prior art has a kind of lachrymal sac drainage tube, and primary structure comprises conduit and bracing frame, and the base angle of bracing frame is connected with an end of conduit, and the axle center hole of conduit communicates with the inboard of bracing frame.There is moulding to have to tear easily the defective of breaking in the bracing frame of this lachrymal sac drainage tube, and there is problem not too smoothly in the end face of its conduit upper end when importing lachrymal sac.
Summary of the invention
The purpose of this utility model just provides a kind of lachrymal sac drainage tube, tear easily and break the medical-risk that is caused to solve bracing frame that prior art exists, with and the end face of conduit upper end problem not too smoothly when importing lachrymal sac.
The technical solution of the utility model is: comprise conduit and bracing frame, the bottom of bracing frame is connected with an end of conduit, and the axle center hole of described conduit communicates with the inboard of bracing frame; On the tube wall of the described conduit first half, be provided with a plurality of apertures.Described bracing frame is a loop configuration, and its underpart is a U-shaped, and the upper end of described conduit is connected with the bottom of this bracing frame U-shaped is vertical.2, lachrymal sac drainage tube according to claim 1 is provided with the inclined-plane in the both sides of the upper end of described conduit.
A drift angle at described bracing frame is connected with a capillary vessel, and the hole of this capillary vessel communicates with the inboard of bracing frame.
Be provided with slick and sly conical tip in the outer end of described capillary vessel.
A drift angle at described bracing frame is connected a capillary vessel respectively with the bottom, and the inboard of the Kong Junyu bracing frame of this capillary vessel communicates.
Be provided with slick and sly conical tip in the outer end of described capillary vessel.
Described conduit, bracing frame and capillary vessel are made by soft silicone rubber.
Bracing frame of the present utility model relies on the elastic return original state of himself after importing the lachrymal sac road, can wash fully and administration the foraminous zone in zone and conduit top that bracing frame supported by conduit, can reach good therapeutic effect, the inclined-plane of conduit upper end makes importing more smooth and easy; The U-shaped structure of bracing frame can be optimized production technology, guarantees product quality.Capillary vessel of the present utility model also can be treated lacrimal ductule.

The specific embodiment
Referring to Fig. 1, this embodiment comprises conduit 1 and bracing frame 2, and the bottom of bracing frame 2 is the U-shaped structure, and two upper end connects the flat-top limit, and two drift angles are arc transition.Be connected with the upper end of conduit 1 in the middle of the lower end of bracing frame 2, the axle center hole of described conduit 1 communicates with the inboard of bracing frame 2.On the tube wall of described conduit 1 first half, be provided with two row's apertures 3, be provided with inclined-plane 6 in the both sides of the upper end of described conduit 1.This embodiment is used for the treatment of the patient of treatment lachrymal sac road inflammation.
Referring to Fig. 2 and Fig. 3, this embodiment is connected with a capillary vessel 4 on the side angle top of the bracing frame 2 of a last embodiment, and the hole of this capillary vessel 4 communicates with the inboard of bracing frame 2.Capillary vessel 4 can with the top of bracing frame 2 square to (as shown in Figure 2), also can be towards upper right oblique (as shown in Figure 3).The outer end of described capillary vessel 4 is provided with slick and sly conical tip, is beneficial to import focus.This embodiment is used for treating simultaneously the patient of an inflammation of lachrymal sac road and a lacrimal ductule inflammation.
Participate in Fig. 4, this embodiment has increased a capillary vessel 5 again on the basis of a last embodiment, and this capillary vessel 5 is connected the bottom of bracing frame 2, with described capillary vessel 4 in the same side.The shape of capillary vessel 5 is identical with capillary vessel 4, and its axle center hole also communicates with the inboard of bracing frame 2.
This utility model conduit 1, bracing frame 2, capillary vessel 4 and 5 are by soft and have certain elastic material (as soft silicone rubber) and make.
Utilize silk thread that bracing frame 2 positions are tied up by the patient during operation, through the intranasal backward haulage to lachrymal sac, after traction stops, the bracing frame 2 of degree of being elongated distortion restores to the original state, and utilizes the crossbeam of bracing frame 2 upper ends, and the lachrymal sac medial wall is supported, conduit 2 is fixed, after conduit 2 is fixed, can cut off conduit 2 bottom redundances, finish the fixation procedure of conduit along muzzle.Aperture 3 on the first half tube wall of conduit 2 is for flushing pus and blood and medicine disperse usefulness, pours into flushing liquor by medical demand from the lower end of conduit 2 by the patient and carries out the focus cleaning treatment and impose Drug therapy.Patient's postoperative inlying catheter a few days can continue to observe, treat, until reaching healing.According to the improvement of clinical sign, extract gently by the lower end of intranasal clamping conduit 2 with operating forceps by the patient again, promptly finish therapeutic process.
Fig. 2 and Fig. 3 shown in embodiment in capillary vessel 4 and 5 in distraction procedure, be imported in (up and down) lacrimal ductule of lachrymal sac liquid output pathway, and this capillary vessel is longer than external part and should be cut after drainage tube is fixing, makes the conducting of capillary vessel two ends.This utility model can be used for lachrymal sac road and lacrimal ductule inflammation are treated simultaneously.
