[0022] The structural features of the present invention are now described in detail with reference to the accompanying drawings.

[0023] See also Figure 1-Figure 5 A tear plug remover comprises an expander 1 and an implanter 2. The implanter 2 and the expander 1 are connected to form an integral structure in a detachable manner. For the convenience of connection, a threaded connection method can be adopted between the implanter 2 and the expander 1. An adaptable external threaded connection end 13 and an internal threaded connection end 22 are respectively provided at the docking end of the expander 1 and the implanter 2. When docking, the external threaded connection end 13 and the internal threaded connection end 22 are screwed together to quickly complete the assembly of the implanter 2 and the expander 1. An expansion tip 11 and an implantation column 21 are respectively provided at the end of the expander 1 and the implanter 2 away from the docking. The expansion tip 11 is used to expand the tear point tissue, and the implantation column 21 is used to place the tear point plug and insert the tear point plug into the tear point. In order to facilitate the removal of the lacrimal plug inserted into the lacrimal point tissue, an airway 12 is provided in the middle of the expander 1, and an air inlet hole 15 is provided at the expansion tip 11 of the airway 12, and a negative pressure connection end 14 is provided at the other end. In order to avoid the negative pressure connection end 14 affecting the connection between the implanter 2 and the expander 1, a cavity 23 with a size adapted to the negative pressure connection end 14 is provided at the docking end of the implanter 2. When the implanter 2 is docked with the expander 1, the negative pressure connection end 14 will enter the cavity 23.

[0024] It also includes a negative pressure generator 3, wherein the negative pressure generator 3 is a syringe or a suction balloon, etc. After the expander 1 and the implanter 2 are separated, the negative pressure generator 3 can be connected to the negative pressure connection end 14 to form a negative pressure in the airway 12, which is used to absorb the punctal plug in the lacrimal tissue. Specifically, when removing the punctal plug, the negative pressure connection end 14 generates negative pressure and forms an adsorption force at the position of the air inlet 15. When the expansion tip 11 is inserted into the center hole of the punctal plug, the punctal plug will be adsorbed, thereby facilitating the removal of the punctal plug. In order to facilitate the adsorption of the punctal plug, the air inlet 15 is located on the tip or side wall of the expansion tip 11. When the air inlet 15 is set at the tip of the expansion tip 11, non-through punctal plugs can be adsorbed. When the air inlet 15 is set on the side wall of the expansion tip 11, both non-through punctal plugs and through punctal plugs can be adsorbed.

[0025] The tear punctum plug remover of the present invention is easy to operate and has a simple structure. On the one hand, it has the function of inserting and removing the tear punctum plug. On the other hand, during use, negative pressure is formed inside the tear punctum plug to absorb and remove the tear punctum plug from the tear punctum tissue. There is no need to use saline flushing to remove the tear punctum plug, which can reduce the discomfort when removing the tear punctum plug and also improve the removal efficiency of the tear punctum plug.

[0026] Specifically, during use, the negative pressure generator 3 is a conventional syringe. First, the syringe is mounted on the negative pressure connection terminal 14, with the expanded tip 11 contacting the central hole of the punctal plug. The syringe is then pulled, creating a negative pressure state within the airway 12, thereby attracting the punctal plug. The extractor is then used to remove the punctal plug and remove it from the body.

[0027] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
