Embodiment Construction

[0220] figure 1 It is a schematic diagram of the lacrimal tissue (DCR) tool 10 according to the application of the present invention. DCR Tools 10 is used to perform lacrimal tissue, that is, a bypass between the tear system and the nasal cavity. The DCR tool 10 includes a lacrimal tissue (DCR) guide 20 and a proximal handle 738 for some applications ( Figure 7 The perforation shaft 30 of the distal perforation shaft perforation tip 32 is configured to form bypass between the outer side, tears and nasal mucosa in the outer side, tears and nasal mucosa (for example, hereinafter Refer Figures 4A to 4B The described).

[0221] DCR guides 20 include:

[0222] The nasal guide member 40 is configured to insert into the nasal cavity and has a lateral distal opening 42;

[0223] The tear guide member 50 is formed to define a tear guide passage 52, the tear guide member is configured to push through the tears pass through the lacrimal passage (as shown below) at the distal perforation sha...

Abstract

Embodiments of the present invention provide methods for performing dacryocystorhinostomy and an apparatus for performing dacryocystorhinostomy (DCR), the apparatus comprising a dacryocystorhinostomy (DCR) tool, which includes a perforating shaft having a distal perforating-shaft perforating tip 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 and a DCR guide, which includes a nasal guide component, which is configured to be inserted into the nasal cavity and has a nasal- guide channel having a proximal opening and an at least partially laterally facing distal opening, and a lacrimal guide component, which is shaped so as to define a lacrimal-guide channel that is configured to orient the distal perforating-shaft perforating tip with respect to the DCR guide during advancing of the distal perforating-shaft perforating tip through a lacrimal passageway and into the lacrimal sac, until the distal perforating-shaft perforating tip at least crosses the laterally facing distal opening of the nasal guide component, and wherein the DCR guide is configured to constrain the laterally facing distal opening of the nasal guide component to fall in a path of advancement of the distal perforating-shaft perforating tip.

Description

[0001] Cross-reference related application [0002] The present application requires the benefits of the priority of the US Temporary Patent Application No. 62 / 828,656 submitted to "Tools and Methods Fordacryocystorhinostomy" submitted on 3 April 2019.
