Abstract: front page image
(EN)The purpose of the present invention is to provide a catheter which has a simple structure while being multi-functional, such as being capable of adsorption, traction, coagulation, and hemostasis of a tissue of a lifeform. Provided is a catheter for an endoscope, comprising: a hole which is disposed in proximity to a distal end of a tube part; and an energy element which is disposed within the tube part to the proximal end side of the hole. The energy element further comprises: an energy emission part which is positioned in a cavity within the tube part and is capable of emitting a prescribed energy; and a communication path which is formed to include a portion of a surface of the energy emission part and which facilitates communication between the hole and a region within the tube part to the proximal end side of the energy emission part.
(FR)Le but de cette invention est de fournir un cathéter qui a une structure simple, tout en étant multifonctionnel, et qui peut adsorber, tirer, coaguler et former une hémostase d'un tissu vivant. Le cathéter pour endoscope a un trou, à proximité de l'extrémité distale du tube, et une source d'énergie à l'intérieur du tube à l'extrémité proximale du trou. La source d'énergie comprend une partie d'émission d'énergie, dans une cavité à l'intérieur du tube, qui peut émettre une énergie définie, et un trajet de communication. Ce dernier inclut une partie de la surface de la partie d'émission d'énergie, et facilite la communication entre le trou et une région à l'intérieur du tube a l'extrémité proximale de la partie d'émission d'énergie.
