Abstract
The utility model relates to an artificial nasal tear tube, which comprises a medical rubber tube of which the outer diameter ranges from 3 mm to 5 mm and the inner diameter ranges from 2 mm to 4 mm, wherein, one end of the rubber tube presents an inclined plane; the tube wall close to the inclined plane is provided with two to five liquid discharge holes and is uniformly distributed with two or more arms, or a flap inclining downwards is arranged on the outer tube wall. The artificial nasal tear tube can enduringly replace a film nasal tear tube and can drain tears effectively for a long time. Moreover, after arranged in a nasal tear tube, the artificial nasal tear tube of the utility model can be automatically fixed on the nasal tear tube and can not disengage.
Description
This utility model belongs to uses operation method, the utensil of treatment obstruction of naso lacrimal duct and chronic dacryocystitis, particularly a kind of Artificial nasal tear tube.
The current retrograde justice pipe of nasolacrimal duct that has Chinese patent to be put down in writing for No. 90224220.2 with the utensil of retrograde implantation treatment obstruction of naso lacrimal duct of Artificial nasal tear tube and chronic dacryocystitis, there are two triangle bifurcateds the upper end that is characterized as pipe of this adopted pipe, and pipe shaft has some outages.When using the retrograde justice pipe of this nasolacrimal duct to implant in the nasolacrimal duct, the wound hyperplastic tissue in the nasolacrimal duct can be by outage with the retrograde adopted pipe plug plug of nasolacrimal duct.In addition, for the nasolacrimal duct made from the silica gel justice pipe that drives in the wrong direction, to soak the rear surface smooth because silica gel tube is organized liquid, thereby very easily come off from nasolacrimal duct.
The purpose of this utility model is to provide a kind of energy smooth along ground drain tear and the Artificial nasal tear tube in the implantable bone nasolacrimal duct firmly in order to overcome above-mentioned weak point.
This utility model is achieved in that external diameter 3-5mm, the medical sebific duct one end beveling of internal diameter 2-4mm, to enlarge the surface area of drain inlet, entering the mouth when being stopped up near having the make provision against emergencies inclined-plane of pipe of 2-5 outage on the tube wall on inclined-plane by secretions, tear also can be drained by outage, being evenly distributed with the arm more than 2 or 2 near the pipe outer wall on inclined-plane or being processed with some downward-sloping lobes, so that Artificial nasal tear tube is fixed in the bone nasolacrimal duct at the pipe outer wall.
When using this utility model treatment obstruction of naso lacrimal duct or dacryocystisis, the inflammatory tissue that will block nasolacrimal duct is removed earlier, with lead-in wire Artificial nasal tear tube is driven in the wrong direction in the bone nasolacrimal duct and lachrymal sac that importing dredged then, tractive Artificial nasal tear tube lower end goes between downwards again, lobe on the Artificial nasal tear tube is opened fasten the bone lacrimal canal fold or the arm on the Artificial nasal tear tube is propped up on bone nasolacrimal duct inlet, remove lead-in wire, this moment Artificial nasal tear tube the inclined-plane, outage should stretch in the lachrymal sac.
This utility model is compared with existing technology, permanently alternative membrane nasolacrimal duct and drain tear long-term effectively, and can be fixed on voluntarily after in the implantable bone nasolacrimal duct on the bone nasolacrimal duct and do not come off.
Fig. 1 is the Artificial nasal tear tube cutaway view of embodiment 1;
Fig. 2 is the Artificial nasal tear tube organigram of embodiment 2.
Now the utility model is described in further detail in conjunction with the accompanying drawings and embodiments.
Embodiment 1: as shown in Figure 1, Artificial nasal tear tube comprises external diameter 3-5mm, the medical silicone tube 1 of internal diameter 2-4mm, and an end of medical silicone tube 1 is inclined-plane 2, near 2-5 outage 3 being arranged on the tube wall on inclined-plane 2 and being evenly distributed with arm 4 more than 2 or 2.
Embodiment 2: as shown in Figure 2, Artificial nasal tear tube comprises external diameter 3-5mm, the medical silicone tube 1 of internal diameter 2-4mm, and an end of silica gel tube 1 is inclined-plane 2, near on the wall on inclined-plane 2 2-5 outage 3 is being arranged, and is provided with the lobe 5 under some being tilted on the pipe outer wall.
Claims (1)
1, a kind of Artificial nasal tear tube, comprise external diameter 3-5mm, the medical sebific duct of internal diameter 2-4mm, an end that it is characterized in that pipe is the inclined-plane, near 2-5 outage being arranged on the tube wall on inclined-plane, some downward-sloping lobes are being arranged on the pipe outer wall or on the close pipe outer wall on inclined-plane, be evenly distributed with arm more than 2 or 2.
