SILICONE TUBE INCLUDING BIODEGRADABLE POLYMER KNOT FOR SILICONE TUBE INTUBATION IN NASOLACRIMAL DUCT OBSTRUCTION

摘要

The present invention relates to a biodegradable polymer knot of a silicone tube used for silicon tube intubation in a nasolacrimal duct obstruction, the knot enabling a silicone tube (10) to be easily removed even with the conjunctiva by using a biodegradable polymer with respect to a part in which a knot is made by binding an end of the silicone tube (10) after carrying out silicone tube intubation in a nasolacrimal duct obstruction. The present invention can remove the silicone tube (10) by using the conjunctiva without additional surgery since a knot part for binding the silicone tube (10) in a lacrimal duct obstruction intubation procedure is manufactured from a biodegradable polymer. In addition, the present invention enables the knot portion of the silicone tube (10) to be located at a suitable position in the nasal cavity by displaying the same for easy viewing. In addition, the present invention can provide the silicon tube (10) provided such that the inner diameters of the lacrimal canal and the musculotubal canal do not contract according to the passage of time or external injury.
