Abstract
The invention discloses a nasolacrimal duct bracket for wing-shaped fixed parts, which comprises a drainage tube and at least two wing-shaped fixed parts, wherein one end of the wing-shaped fixed part is fixed at the head end of the drainage tube, while the other end extends radically and obliquely. The nasolacrimal duct bracket for the wing-shaped fixed parts has the advantages that the bracket is convenient to collect tears and drain, can maintain smooth movement of the nasolacrimal duct, has simple manufacture, and so on.
Description
Technical field
The present invention relates to treatment of diseases instruments such as obstruction of naso lacrimal duct and chronic dacryocystitis, relate in particular to the lacrimal canal bracket of band wing fixed part.
Background technology
Obstruction of naso lacrimal duct and chronic dacryocystitis all are common ocular disease, at present, mainly treat with lacrimal passage spy art and nasal cavity lachrymal sac anastomosis.It is little, simple to operate that lacrimal passage is visited the art damage, but the long-term effect instability, and the relapse rate height is not suitable for the treatment of chronic dacryocystitis especially, makes its application be subjected to certain limitation.In the method for treatment obstruction of naso lacrimal duct and chronic dacryocystitis, what effect was preferable, success rate is higher is dacryocystorhinostomy, still at present, this art operation is complicated, and intraoperative hemorrhage is many, and operating time is long, the operation rear face leaves cicatrix, can not undergo surgery because of surgical contraindication sometimes; Simultaneously, operation has changed the original anatomical passageway of lacrimal passage, in case postoperative anastomotic stoma fiber forms cicatrix or ossified, causes anastomotic stoma to block so that cause that lacrimal passage blocks again, loses the chance of operation once more.In order to reduce surgical injury, do not change the original anatomical passageway of lacrimal passage, the method of using lacrimal canal bracket to treat has appearred at present, but the fixed part of existing lacrimal canal bracket has warp architecture mostly, major defect is: the complex manufacturing technology of warp architecture, bending forming difficulty, angle of bend are difficult to guarantee unified; The easy formation of sweep stops the tear house steward's, also is not easy to the collection and the drain of tear; The length of whole fixed part is longer, causes that easily the patient does not feel like oneself behind the implantation nasolacrimal duct.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provides a kind of and is convenient to collect tear, is convenient to drain, can keeps that nasolacrimal duct is unobstructed, processing technology is simply with the lacrimal canal bracket of wing fixed part.
For solving the problems of the technologies described above, the present invention by the following technical solutions.
A kind of lacrimal canal bracket with the wing fixed part, it comprises drainage tube and at least two wing fixed parts, and described wing fixed part one end is fixed in the head end of drainage tube, and the other end is the oblique extension of aplysia punctata.
The angle α size of each wing fixed part and drainage tube is 20 °～70 °.
The angle α size of each wing fixed part and drainage tube is preferably 30 °～50 °.
The end of described drainage tube is a bevel shape opening, also offers aperture in bevel shape open upper end.
Compared with prior art, the invention has the advantages that: wing fixed part one end is fixed in the head end of drainage tube, the other end is the oblique extension of aplysia punctata, during its implanted patient's nasolacrimal duct, can draw in, be convenient to install, the back wing fixed part that is in place recovers original shape automatically and tension force is provided, and plays fixation; Simple in structure, without any the structure that stops the tear house steward, be convenient to tear is collected, help tear is imported in the drainage tube, keep the unobstructed of nasolacrimal duct; Because the wing fixed part is the oblique extension of aplysia punctata, has removed warp architecture, make processing technology obtain simplifying, be easy to guarantee that the shaping of wing fixed part is unified; Wing fixed part contraction in length reduces with the contact area of patient's lachrymal sac, can alleviate the subject discomfort sense.

The specific embodiment
As shown in Figure 1 and Figure 2, the lacrimal canal bracket of band wing fixed part of the present invention, it comprises drainage tube 1 and at least two wing fixed parts 2, wing fixed part 2 is provided with four in the present embodiment, one end of each wing fixed part 2 is fixed in the head end of drainage tube 1, and the other end is the oblique extension of aplysia punctata, has removed warp architecture, make processing technology obtain simplifying, be easy to guarantee that the shaping of each wing fixed part 2 is unified.Each wing fixed part 2 is 20 °～70 ° with the angle α size of drainage tube 1, is preferably 30 °～50 °, is 35 ° in the present embodiment.Wing fixed part 2 contraction in lengths, little with the contact area of patient's lachrymal sac, can alleviate the subject discomfort sense.During its implanted patient's nasolacrimal duct, can draw into thin tube-like in, be convenient to install, the back wing fixed part 2 that is in place recovers original shapes automatically also provides tension force, plays fixation.The end of drainage tube 1 is a bevel shape opening 4, also offers aperture 3 in bevel shape opening 4 upper ends.The lacrimal canal bracket of band wing fixed part of the present invention, simple in structure, without any the tear house steward is formed the structure that stops, be convenient to tear is collected, help tear is imported in the drainage tube 1, keep the unobstructed of nasolacrimal duct.
When adopting lacrimal canal bracket of the present invention that the patient is implemented tube planting operation, earlier whole wing fixed part 2 is drawn in, put in place by the guide wire guiding.After this, wing fixed part 2 reverts to open aplysia punctata, tension force is provided and is fixed in the lachrymal sac, is used to collect tear, and tear is imported in the drainage tube 1; Simultaneously, wing fixed part 2 is fixed on drainage tube 1 in the nasolacrimal duct, is used to dredge nasolacrimal duct and drain tear.
