Title (EN) TOOLS AND METHODS FOR DACRYOCYSTORHINOSTOMY
(FR) OUTILS ET PROCÉDÉS DE DACRYOCYSTORHINOSTOMIE
Abstract:
(EN) A dacryocystorhinostomy (DCR) tool (10) includes a perforating shaft (30) having a distal perforating tip (32) configured to form a bypass between a lacrimal sac and a nasal cavity through a lateral side of the lacrimal sac, a lacrimal bone, and nasal mucosa. A DCR guide (20) includes a nasal guide component (40) configured to be inserted into the nasal cavity and having a distal guide tip (42); and a lacrimal guide component (50) shaped so as to define a guide channel (52) that orients the DCR guide (20) with respect to the distal perforating tip (32) during advancing of the distal perforating tip (32) through a lacrimal passageway and into the lacrimal sac, until contact of the distal perforating tip (32) with the distal guide tip (42) blocks further advancing of the distal perforating tip (32). The DCR guide (20) constrains the distal guide tip (42) to fall in a path of advancement of the distal perforating tip (32). Other embodiments are also described.
(FR) Un outil de dacryocystorhinostomie (DCR) (10) selon la présente invention comprend un arbre de perforation (30) ayant une pointe de perforation distale (32) configurée pour former une dérivation entre un sac lacrymal et une cavité nasale à travers un côté latéral du sac lacrymal, un os lacrymal et une muqueuse nasale. Un guide DCR (20) comprend un composant de guidage nasal (40) configuré pour être inséré dans la cavité nasale et ayant une pointe de guidage distale (42) ; et un composant de guidage lacrymal (50) formé de façon à définir un canal de guidage (52) qui oriente le guide DCR (20) par rapport à la pointe de perforation distale (32) pendant l'avancement de la pointe de perforation distale (32) à travers un passage lacrymal et dans le sac lacrymal, jusqu'à ce que le contact de la pointe de perforation distale (32) avec la pointe de guidage distale (42) bloque davantage l'avancement de la pointe de perforation distale (32). Le guide DCR (20) contraint la pointe de guidage distale (42) à tomber dans un trajet d'avancement de la pointe de perforation distale (32). L'invention décrit également d'autres modes de réalisation.
