CA 2514600

To provide a tool for safely and reliably securing a route for endermically approaching the interior of the body; more specifically, an endoscope-equipped puncture balloon that is designed to allow a balloon that does not immediately burst when punctured by a puncturing needle or the like to be used as a target, and that can be used by installing or inserting an endoscope in a tube holding such balloon. In a thin-walled main body tube 1 equipped with an endoscope- installed section at the rear end, a balloon 2 is disposed on the front surface thereof, and a branch tube 4 communicating with the interior of the balloon 2 in a gas-liquid flow manner is disposed on the main body tube 1, the branch tube 4 having a connector 5 annexed to the rear end thereof; thus it is not until the liquid in the balloon is absorbed without the balloon immediately bursting when punctured by a puncturing needle that a bore can be secured until the balloon is contracted.

L'invention concerne un instrument permettant de sécuriser de façon fiable une voie de pénétration endoscopique à l'intérieur du corps humain, plus spécifiquement, un ballonnet à perforer pourvu d'un endoscope, lequel n'éclate pas immédiatement lorsqu'il est perforé par une aiguille de perforation ou analogue et est utilisé comme une cible, cela par installation ou insertion d'un endoscope dans un tube maintenant ledit ballonnet. Le ballonnet (2) est placé sur la surface avant d'un tube principal (1) à paroi mince, présentant, à son extrémité arrière, une section pourvue d'un endoscope, et un tube auxiliaire (4), qui communique avec l'intérieur du ballonnet (2) pour permettre le passage d'un gaz ou d'un liquide, est placé sur ledit tube principal (1) et présente un raccord (5) monté sur sa partie arrière. Ainsi, ce n'est que quand le liquide se trouvant dans le ballonnet (2) est absorbé, le ballonnet (2) n'éclatant pas immédiatement lorsqu'il est perforé par une aiguille de perforation (12), qu'un orifice peut être sécurisé, c'est-à-dire jusqu'à ce que le ballonnet (2) soit contracté.
