SILICONE TUBE WITH BIODEGRADABLE POLYMER KNOTS FOR INTUBATION IN NASOLACRIMAL DUCT OBSTRUCTION

摘要

The present invention relates to a biodegradable polymer knot of a silicone pipe used in a silicone pipe insertion procedure in a nasolacrimal duct obstruction, which uses biodegradable polymer in a portion where an end of the silicone pipe (10) is tied to make a knot after procedure of silicone pipe insertion in a nasolacrimal duct obstruction and easily removes the silicone pipe (10) by conjunctiva. A knot portion tying the silicone pipe (10) is manufactured by biodegradable polymers in an interlobular duct obstruction inserting procedure, thereby removing the silicone pipe (10) by using the conjunctive without additional procedure. In addition, the present invention displays a knot portion of the silicone pipe (10) to be easily seen and places the knot in a proper location within the nasal cavity. Moreover, the present invention provides a silicone pipe (10) tube provided to prevent a canaliculus and an inner diameter of a nasolacrimal duct from contracting according to injuries or as time goes by.
