Abstract

The invention provides an auxiliary lacrimal duct. The auxiliary lacrimal duct is used for communicating the nasal cavity with the lacrimal sac. The auxiliary lacrimal duct comprises a duct body and a positioning element, the rear end of the duct body penetrates through the nasal cavity mucous membrane, the bone wall and the lacrimal sac mucous membrane so that the nasal cavity can be communicated with the lacrimal sac; the positioning element is arranged at the front end of the duct body and clamped onto the lacrimal sac mucous membrane. The duct body is used for communicating the nasal cavity with the lacrimal sac, and the purpose that tears in the lacrimal sac flow into the nasal cavity can be achieved.

Description

technical field [0001] The present invention relates to an auxiliary lacrimal drainage duct; in particular, it relates to an auxiliary lacrimal drainage duct that is placed on the nasal mucosa, bone wall and lacrimal sac to communicate with the nasal cavity and the lacrimal sac, so as to allow the tears flowing into the lacrimal sac to flow into the nasal cavity. Tube. Background technique [0002] Tears are produced by the lacrimal glands to moisten the surface of the eyeball. Excessive tears flow into the lacrimal sac and then into the nasal cavity through the nasolacrimal duct. [0003] Under normal circumstances, the lacrimal glands secrete tears at any time, but the nasolacrimal ducts may be blocked. There are many reasons for the blocked nasolacrimal ducts. For example, the nasolacrimal ducts are inflamed and bacterial Infection, and then the formation of obstruction phenomenon, affecting the normal drainage of tears. [0004] In order to solve the problem of nasola...
