Abstract
The utility model relates to an implantation duct for nasolacrimal duct. The implantation tube adopts a medical rubber duct, the length of the medical rubber ductand the diameter of the medical rubber duct are near to the length of the nasolacrimal duct and the diameter of the nasolacrimal duct. The top end of the implantation duct is provided with a horn-shaped drain inlet. A horn-shaped head is buckled at the upper end of the nasolacrimal duct after the implantation duct is implanted into the nasolacrimal duct. Thus, the nasolacrimal duct of a patient is unblocked.
Description
This utility model belongs to the improvement of medical apparatus and instruments, is specifically related to a kind of nasolacrimal duct implant.
At present, many patients are arranged, cause and shed tears for a long time, draw nasal cavity lachrymal sac anastomosis because of obstructions such as nasolacrimal duct inflammation, though can deal with problems, operation wound is big, brings misery to patient, and expense is also high, other pipe expanding method, though effective at that time, after a while, still can stop up again.
The purpose of this utility model is at above-mentioned the deficiencies in the prior art part, and a kind of novel nasolacrimal duct implant that can thoroughly solve the nasolacrimal duct blockage problem is provided.
To achieve these goals, the scheme that this utility model solves is, is provided with tubaeform drain inlet on the length medical silicone tube top close with nasolacrimal duct with diameter, and behind this pipe implantation nasolacrimal duct, head of the trumpet is stuck in the upper end of nasolacrimal duct, can make nasolacrimal duct unimpeded.
Advantage of the present utility model, the one, simple in structure, be easy to make; The 2nd, adopt the medical silica-gel material to make, be used for both not had any pair, toxic action behind the human body, can reach the therapeutic effect that gets instant result again; The 3rd, easy to operation, can alleviate the hardship and the expense of patient's operation greatly.
Fig. 1 is a structural representation of the present utility model
Below in conjunction with accompanying drawing this utility model embodiment is described in detail.
By shown in Figure 1, adopt the length medical silicone tube (1) close with nasolacrimal duct with diameter, the top of sebific duct is provided with loudspeaker eight shape drains inlets (2), and after this pipe was implanted nasolacrimal duct, head of the trumpet was stuck in the upper end of nasolacrimal duct, can make patient's nasolacrimal duct unimpeded.During use, with the operation silk thread from nasolacrimal duct end opening tractive upwards with implant, because implant adopts silica gel material to make, implant has certain elasticity, so in the process of tractive implant, can dwindle when the tear stains of stenosis, when the implant tractive to tear stains behind the location suitable for reading, head of the trumpet is stuck in suitable for reading, and the implant of distortion can restore to the original state by nature, and it is unimpeded to reach nasolacrimal duct.
Claims (1)
1, this utility model relates to a kind of nasolacrimal duct implant, it is characterized in that: be provided with tubaeform drain inlet (2) on length medical silicone tube (1) top close with nasolacrimal duct with diameter.
