Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required to be used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive labor.

Fig. 1 is a schematic structural view of a novel lacrimal drainage tube provided in this embodiment;

shown in the figure: 1. a probe; 2. a feeding pipe; 3. a first implantation tube; 4. a second implantation tube; 5. a short connecting pipe; 6. a punctum limit plug.

Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

The embodiment can be known from the attached drawing 1 of the specification, and this scheme is a novel lacrimal passage drainage tube, including probe 1, the cover is equipped with on probe 1 and is sent into pipe 2, the middle-section part that sends into pipe 2 is open structure, probe 1 follows send into the open structure part of pipe 2 and insert wherein, the one end of sending into pipe 2 is connected with implantation tube 3 No. one, the one end of implantation tube 3 No. two is connected with implantation tube 4 No. two, the end of implantation tube 4 No. two is provided with connecting stub 5, be connected with the spacing bolt 6 of lacrimal point on connecting stub 5.

As can be seen from the attached figure 1 of the specification, the delivery pipe 2 is a medical grade synthetic fiber nylon pipe, and the second implantation pipe, the first implantation pipe, the punctum limiting bolt and the short connecting pipe are medical grade high-activity adsorption silicic acid gel.

In the scheme, the connecting short pipe 5 and the second implantation pipe 4 form a 90-degree right angle, and the insertion part between the probe 1 and the feeding pipe 2 is in seamless fit.

It is important to point out that in the specific implementation process, the probe 1 is firstly sleeved into the feeding tube 2 and is fed into the lacrimal passage from the punctum of the human body to the middle turbinate position, the probe 1 cannot be continuously fed due to the natural physiological bending of the inferior turbinate, at the moment, the probe 1 needs to be pulled out, the probe is continuously fed through the feeding tube 2 (the feeding tube 2 has certain hardness and flexibility), the feeding tube 2 is taken out by a tractor or a hand after passing through the nasal cavity, the punctum limit bolt 6 is fixed at the punctum, and the feeding tube 2, the redundant first implantation tube 3 and the redundant second implantation tube are subtracted at the position parallel to the nostril.

In the technical scheme, the feeding pipe 2 can be bent through the opening structure, and the opening structure can be inserted into the probe 1 after bending to assist in inserting into the lacrimal passage.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
