Description

Technical Field

[0001] The present application relates to a nasolacrimal duct with a balloon. Background Art

[0002] During the insertion of the tear duct, a convex part is generally required to be preset on the tear duct for fixation. However, the convex part affects the operation of the insertion surgery and may also cause trauma to the operation site. Now, some methods use a balloon to make it possible to obtain the convex part by filling the convex part with fluid later. However, the existing treatment method is difficult to take into account the tear duct's function of draining tears. In fact, it is hoped that the expansion of the balloon will promote self-healing, and the drainage function of the built-in tear duct is abandoned. Utility Model Content

[0003] In order to solve the above problems, the present application proposes a nasolacrimal duct with a balloon, including a lacrimal duct, an auxiliary tube arranged on the side of the lacrimal duct, a balloon fixedly arranged on the outside of the auxiliary tube, and an introduction part arranged at the position of the auxiliary tube corresponding to the balloon; the auxiliary tube and the lacrimal duct are fixedly connected, and the balloon is wrapped and arranged on the outside of the auxiliary tube and the lacrimal duct. The present application adopts an auxiliary tube and a lacrimal duct that are separately arranged, and the auxiliary tube is used to cooperate with the balloon, so that the balloon can be easily introduced in the introduction, and after the introduction, fluid is introduced into the balloon to swell the balloon, and finally the insertion is completed without affecting the diversion function of the lacrimal duct itself.

[0004] Preferably, a silicone plug is provided on the auxiliary pipe.

[0005] Preferably, the silicone plug includes a plug body and an arc-shaped convex head arranged toward the balloon. The present application can plug the auxiliary tube with the silicone plug. During the introduction, the fluid is introduced through the silicone plug by using a needle tube, and then the needle tube is pulled out. The silicone plug is naturally closed, that is, the introduction is completed, and the needle tube is pulled out, that is, the natural closure is completed. In general, the silicone plug can be inserted into the hole on the auxiliary tube to introduce the silicone adhesive, and then hang down toward the balloon direction, that is, an arc-shaped convex head can be formed, and the silicone adhesive can also automatically seal the hole.

[0006] Preferably, the introduction part is a connecting seam provided on the balloon and the auxiliary tube, the part of the auxiliary tube corresponding to the connecting seam is provided in an outer arc shape, and the connecting seam is provided to extend along the axial direction of the auxiliary tube. The introduction part of the present application can adopt a connecting seam structure, because during introduction, the needle tube can provide positive pressure, which can be opened in the direction of the balloon, and after introduction, due to the pressure in the balloon part, the outer arc-shaped wall of the auxiliary tube itself makes the connecting seam self-closed, and the structure is simple, but it has a very good one-way introduction effect.

[0007] Preferably, the auxiliary tube and the tear duct are an integrally extruded pipe, and a middle partition is arranged in the pipe so that one side forms the auxiliary tube and the other side forms the tear duct.

[0008] Preferably, it also includes a lead-out tube, which is connected to the balloon through the lead-out hole, and is fixedly connected to the auxiliary tube and the lacrimal duct. A closing head is provided at the outer end of the lead-out tube, and a closing head marking line corresponding to the closing head is provided at the position of the closing head.

[0009] Preferably, the auxiliary tube, the tear duct and the outlet tube are all integrated extruded tubes, and two parallel intermediate partitions are arranged in the tube so that one side forms the auxiliary tube, the other side forms the outlet tube, and the middle part forms the tear duct. The present application can be combined in the form of an introduction part in the form of a connecting seam and an outlet tube provided with a closed head. This method is simpler to operate and has better reliability during the operation. When removing, the upper part of the plug can be cut off or the needle can be inserted to lead out. The operation method is more diverse and more convenient.

[0010] Preferably, the balloon is extended to the outside of the nasolacrimal duct. The present application may also adopt a long balloon arrangement so that when taking it out, the balloon can be easily broken, making it convenient to take out the lacrimal duct and the balloon.

[0011] This application can bring the following beneficial effects:

[0012] 1. The present application adopts a separately arranged auxiliary tube and tear duct, and the auxiliary tube is used to cooperate with the balloon, so that the balloon can be easily introduced into the introduction tube, and then fluid is introduced into the balloon to inflate the balloon, and finally the insertion is completed without affecting the drainage function of the tear duct itself.

[0013] 2. The present application can plug the auxiliary tube with a silicone plug. During introduction, a needle is used to pass through the silicone plug to introduce the fluid, and then the needle is pulled out. The silicone plug is naturally closed, and the introduction is completed. The needle is pulled out, and the natural closure is completed. Generally, the silicone plug can be used to introduce silicone adhesive into the hole on the auxiliary tube, and then hang down toward the balloon to form an arc-shaped convex head, and the silicone adhesive can also automatically seal the hole.

[0014] 3. The present application can be combined in the form of an introduction portion in the form of a connecting seam and an outlet tube provided with a closed head. This method is simpler to operate and has better reliability during the operation. When removing, it can be done by cutting off the upper part of the plug or by inserting a needle tube to lead it out. The operation methods are more diverse and more convenient.

A closed head 11 is provided at the outer end of the lead-out tube 9, and a closed head marking line 12 corresponding to the closed head 11 is provided at the position of the closed head 11. The auxiliary tube 2, the lacrimal duct 1 and the lead-out tube 9 are all integrated extruded pipes, and two parallel intermediate partitions are provided in the pipe so that the auxiliary tube 2 is formed on one side, the lead-out tube 9 is formed on one side, and the lacrimal duct 1 is formed in the middle.

[0030] When in use, the present application is pulled to a proper position by a traction line, etc., and then introduced by a syringe through the auxiliary tube 2, so that the fluid passes through the auxiliary tube 2 and the introduction part 4 (in this case, the introduction part 4 can be a hole-type structure), and the fluid is injected into the balloon 3. Thermosensitive chitosan can be selected, which is liquid at room temperature and jelly-like near body temperature, and is not easy to seep out of the balloon 3. Then the syringe is pulled out, and the silicone plug 5 is self-sealed, and the assembly is completed.

[0032] The balloon 3 is extended to the outside of the nasolacrimal duct 1 .

[0033] When in use, the present application is pulled to a proper position by a traction line, etc., and then introduced by a syringe through the auxiliary tube 2, so that the fluid passes through the auxiliary tube 2 and the introduction part 4 (in this case, the introduction part 4 can be a hole-type structure), and the fluid is injected into the balloon 3. Thermosensitive chitosan can be selected, which is liquid at room temperature and gel at near body temperature, and is not easy to seep out from the balloon 3. Then the syringe is pulled out, and the introduction part is self-sealed, and the assembly is completed. If it needs to be extracted, since the balloon 3 is long, the bottom of the balloon 3 is directly destroyed, and the fluid flows out of the balloon 3, and then it can be extracted.
