Technical Field

The application relates to a conjunctival sac nasal cavity anastomosis drainage tube.

Background

Lacrimal passage obstruction is a common disease, is easy to cause damage to cornea, dacryocystitis and the like, and the current treatment methods include irrigation, probing, tube placement, nasal cavity dacryocystitis, endoscopic nasal cavity dacryocystitis and the like. However, some patients cannot be treated by the above methods due to serious obstruction, congenital absence of lacrimal passages and the like, and some patients adopt a direct conduction arrangement mode, but the connection mode of the arrangement has a problem of self fixation and a certain compatibility.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, the present application provides a conjunctival sac nasal cavity anastomosis drainage tube, which comprises a tube body, wherein a fixing ring is arranged at the upper part of the tube body, an embedding block is fixedly connected at the lower part of the tube body, and a leading-out hole is arranged at the lower part of the tube body; the Shore hardness of the embedded block is higher than that of the pipe body. This application is through burying different shoal's hardness between piece and the pipe body for after burying this application, human nature is pressed it and is established, thereby the pipe body has little the deformation, and buries the piece and do not, thereby accomplishes fixedly, and fixed ring then accomplishes fixedly in the top of punctum, thereby avoids this application to fall into within the nasal cavity.

Preferably, the fixed ring is arranged on the outer side of the pipe body and comprises a rectangular outer edge, and arc-shaped edges are arranged on at least two opposite edges of the rectangular outer edge.

Preferably, the retaining ring is progressively thinner in a direction away from the tube body.

Preferably, the embedded block comprises a base block connected with the pipe body, and a hemisphere is arranged below the base block. The application adopts the method that the conjunctival sac and the nasal cavity directly penetrate through the nasal cavity, the treatment effect is obvious, the adhesion can be prevented after the operation, and the requirements of covering mucous membrane tissues, isolating drainage tears and the like are met.

Preferably, the outlet hole is an elliptical hole, and the long axis direction of the elliptical hole is parallel to the axial direction of the pipe body.

Preferably, the outlet hole is formed at a connection portion of the pipe body and the buried block. The drainage hole is an oval hole, so that tears can be conveniently and effectively drained quickly in the using process, adverse consequences such as detention of tears are avoided, the cornea can be protected from friction, the position of the tube body is stabilized, the drainage during tube placement can be ensured to be smooth through the drainage hole, the design of the round ball shape at the top end of the tube body is realized, the operation time is saved, and the safe and convenient placement is ensured; the application is easy to popularize and promote, and the requirements of patients are met.

Preferably, the pipe body, the fixed ring and the embedded block are made of silica gel materials which are integrally formed.

Preferably, the buried block is a solid block.

Preferably, the pipe body and the embedding block are arranged in a smooth transition mode, and the diameter of the cross section of the pipe body is consistent with the maximum diameter of the embedding block.

This application can bring following beneficial effect:

1. according to the fixing device, different Shore hardness between the embedding block and the tube body is utilized, after the fixing device is embedded, a human body naturally presses the embedding block, so that the tube body is slightly deformed, the embedding block is not arranged, the fixing is completed, and the fixing ring is fixed above a punctum, so that the application is prevented from falling into a nasal cavity;

2. the application adopts the method of directly penetrating through the conjunctival sac and the nasal cavity, has obvious treatment effect, can prevent adhesion after operation, and meets the requirements of covering mucous membrane tissues, isolating and draining tears and the like;

3. the drainage hole is an oval hole, so that tears can be conveniently and effectively drained quickly in the using process, adverse consequences such as detention of tears are avoided, the cornea can be protected from friction, the position of the tube body is stabilized, the drainage during tube placement can be ensured to be smooth through the drainage hole, the design of the round ball shape at the top end of the tube body is realized, the operation time is saved, and the safe and convenient placement is ensured; the application is easy to popularize and promote, and the requirements of patients are met.

Detailed Description

In order to clearly illustrate the technical features of the present solution, the present application will be explained in detail through the following embodiments.

In a first embodiment, as shown in fig. 1-3, a conjunctival sac nasal cavity anastomosis drainage tube comprises a tube body 1, a fixing ring 2 is arranged at the upper part of the tube body 1, an embedding block 3 is fixedly connected at the lower part of the tube body 1, and a leading-out hole 8 is arranged at the lower part of the tube body 1; the shore hardness of the embedded block 3 is higher than that of the pipe body 1. The fixed ring 2 is arranged on the outer side of the pipe body 1, the fixed ring 2 comprises a rectangular outer edge 4, and arc-shaped edges 5 are arranged on at least two opposite edges of the rectangular outer edge 4. The fixing ring 2 becomes thinner gradually in a direction away from the tube body 1. The embedded block 3 includes a base block 6 connected to the pipe body 1, and a hemisphere 7 is provided below the base block 6. The outlet 8 is an elliptical hole, and the major axis direction of the elliptical hole is parallel to the axial direction of the pipe body 1. The lead-out hole 8 is provided at the joint of the pipe body 1 and the insert 3. The tube body 1, the fixing ring 2 and the embedded block 3 are made of silica gel material which is integrally formed. The buried block 3 is a solid block. The pipe body 1 and the embedded block 3 are smoothly transited, and the diameter of the cross section of the pipe body 1 is consistent with the maximum diameter of the embedded block 3.

During the use, independently set up the passageway between punctum and nasal cavity, then arrange this application in among the pipeline, make solid fixed ring 2 set up outside the punctum, and bury piece 3 and lead-out hole 8 and all set up in the nasal cavity, lead-out hole 8 sets up in the middle of the nasal cavity, pipe body 1 oppresses to human tissue, certain hemostasis by compression function has, because the shao er hardness of pipe body 1 self is less than the shao er hardness of burying piece 3, consequently, pipe body 1 has certain deformation, bury piece 3 but not warp, consequently, whole deformation has formed solid fixed ring 2+ and has buried piece 3, the setting mode of pipe body 1 of middle setting micro-deformation, thereby final operation location has been accomplished.

The above are merely examples of the present application and are not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement or the like made within the spirit and principle of the present application shall be included in the scope of the claims of the present application.
