Device and method for dacryocystorhinostomy

摘要

A system and method for the placement of an intubation set by means of laser surgery in the lachrymal drainage system without prior entry therein is disclosed. An introducer with an atraumatic inner mandrill therein is inserted into the lachrymal sac section. The atraumatic inner mandril is removed and (one or more) optical fibers or fiber bundles are inserted for illumination to determine proper position and for ablating a drainage channel. The optical fiber or bundle is then removed and a DCR intubation set is positioned through the introducer near the new drainage channel and is then removed leaving the intubation tube in the new drainage channel. One advantage of this device and method is that all aspects of the procedure can be performed through the introducer, thus only requiring a single insertion point, reducing trauma to the lachrymal duct, and reducing the complexity and risk of complication or infection. Another advantage of this device and method is that it can be used with many pre-existing intubation sets used for current DCR procedures, thus the present device and method can easily and cost effectively be introduced as a first line procedure.
