DEVICE FOR EXPANDING AND RESTORING THE TEAR'S CANAL EYE

摘要

What is described here is a device for dilating and restoring the lacrimal duct on the human eye, through which lacrimal fluid flows from the eye into the nasal cavity.The inventive device is provided with the follow components:a first hollow cannula with a distal end which presents at least one longitudinal gap,a guide passing through the first hollow cannula and having a distal end which dilates the distal end of the first cannula in the region of the gap,a hollow body surrounding the outside contour of the first hollow cannula in the distal zone, as well asa second hollow cannula adapted to be pushed over the first hollow cannula and extending up to the end on the proximal side of the hollow body, which is placed on the first hollow cannula so as to lock the latter and prevent it from axial sliding on the proximal side.
