Abstract

Un appareil de canule externe multifonctionnelle (1) pour un coloscope concerne un dispositif auxiliaire pour coloscopie et vise à résoudre les problèmes suivants : une boucle courbée a tendance à se former dans le processus d'alimentation d'un endoscope souple, lorsque de l'eau est injectée dans la cavité entérique, du liquide est drainé hors de l'anus et contamine une table d'examen et des vêtements, et un inconfort de distension abdominale est ressenti par un patient lorsque trop d'air est injecté. L'appareil comprend un premier fil d'acier (7), disposé en spirale dans la paroi épaisse d'une canule externe (1), et un tuyau à quatre voies (4), agencé au niveau de l'extrémité inférieure de la canule externe (1). Le tuyau à quatre voies (4) et la canule externe (1) sont en étroite connexion d'ajustement, une face inclinée (1-5) est pratiquée au niveau de l'extrémité supérieure de la canule externe (1), et l'angle oblique de la face inclinée (1-5) est de 30° à 60 °. Un orifice de drainage (1-6) est formé sur la paroi latérale au niveau de l'extrémité supérieure de la canule externe (1), le tuyau à quatre voies (4) est composé d'un premier tuyau ouvert axialement (4-1), d'une première fermeture à glissière (4-2), d'un premier tuyau ramifié (4-3) et d'un second tuyau ramifié (4-4). La première fermeture à glissière (4-2) est disposée au niveau de l'extrémité ouverte axialement du premier tuyau ouvert axialement (4-1), un tuyau fermé est formé par le premier tuyau ouvert axialement (4-1) au moyen de la première fermeture à glissière (4-2), et le premier tuyau ramifié (4-3) et le second tuyau ramifié (4-4) sont disposés sur les deux côtés du tuyau fermé.
