Abstract

Une pince à ligaturer de canal d'endoscope, comprend un corps (110), un élément central de serrage (100), deux parties de serrage (120) et deux ensembles de commande (200). Des premières fentes de coulissement (111) sont formées sur le corps (110); des secondes fentes de coulissement (121) sont formées sur les parties de serrage (120), et chacune des secondes fentes de coulissement (121) comprend une partie de guidage (1211) et une partie de limitation (1212). Les deux ensembles de commande (200) sont respectivement utilisés pour commander indépendamment les deux parties de serrage (120) afin qu'elles s'ouvrent ou se ferment par rapport à l'élément central de serrage (100). Les ensembles de commande (200) comprennent chacun un bloc coulissant (211) et un élément de commande (212); les blocs coulissants (211) sont agencés dans les secondes fentes de coulissement (121); une fois que les parties de serrage (120) sont fermées par rapport à l'élément central de serrage (100), les blocs de coulissement (211) se fixent dans les parties de limitation (1212); les éléments de commande (212) sont reliés aux blocs de coulissement (211), et une partie de chacun des éléments de commande (212) est positionnée dans la première fente de coulissement respective (111). Dans la pince à ligaturer de canal d'endoscope, les deux ensembles de commande (200) peuvent commander respectivement deux parties de serrage (120) afin qu'elles s'ouvrent ou se ferment indépendamment par rapport à l'élément central de serrage (100). Les premières fentes de coulissement (111) permettent de guider et mettre en place les éléments de commande (212), garantissant ainsi un déplacement stable de ceux-ci (212) le long de la direction de fixation, ce qui empêche le glissement des éléments de commande (212) et assure une utilisation fiable du produit.
