[0005] In order to achieve the above technical purpose, the utility model designs a DCR with drainage function and a post-operative cannulation of the lacrimal duct, including: a left drainage duct, a right drainage duct, a connecting tube, a double-lumen drainage channel, and a drainage port;

[0006] The upper end of the left drainage pipe and the upper end of the right drainage pipe are integrally connected by a connecting pipe to form a U-shaped pipe;

[0007] A double-lumen drainage channel is provided in the left drainage conduit;

[0008] Near the lower end of the left drainage pipe, a drainage port is provided at a left and right symmetrical position; each drainage port corresponds to one of the double-cavity drainage channels;

[0009] Preferably, the upper ends of the left drainage conduit and the right drainage conduit are both provided with flushing ports; a guide needle can be inserted into the left drainage conduit and the right drainage conduit through the flushing ports;

[0010] Preferably, a flushing port plug is detachably mounted on the flushing port;

[0011] Preferably, a guide needle groove is provided at the lower end of the left drainage pipe and the right drainage pipe and located inside the left drainage pipe and the right drainage pipe; after the guide needle enters the left drainage pipe and the right drainage pipe, its head end is placed in the guide needle groove to ensure that the position of the guide needle is fixed.

[0012] The beneficial effects of the utility model are:

[0013] The artificial tear duct designed in the utility model is implanted from the upper tear duct and the lower tear duct respectively, and the end is located in the nasal cavity, and is used for treating tear duct obstruction and draining tears. BRIEF DESCRIPTION OF THE DRAWINGS
