Title
(EN) COLONOSCOPE FOR REMOVING COLORECTAL POLYPS
(FR) ENDOSCOPE D'ABLATION DE POLYPES COLORECTAUX
Abstract
(EN)
According to an embodiment a polypectomy device is disclosed for removing a polyp comprising an outer tube (220) comprising a distal end and a proximal end; and a slidably disposed wire arranged in the outer tube and extending between the distal and proximal end comprising a snare loop (110) at the distal end; and controlling means operatively coupled to the wire at the proximal end; wherein the controlling means are configured to slide the wire such that the snare loop (110) extends out the outer tube at the distal end in an open condition for placing the snare loop around the polyp; wherein the outer tube further comprises cutting means at the distal end configured to scrape the polyp, and wherein the controlling means are further configured to, when the snare loop is in the open condition, slide (203) the cutting means with respect to the outer tube towards the polyp for removing it.
(FR)
Selon un mode de réalisation la présente invention concerne un dispositif de polypectomie qui permet d'enlever un polype et qui comporte un tube externe (220) comprenant une extrémité distale et une extrémité proximale ; un fil disposé de manière à pouvoir coulisser dans le tube externe et s’étendant entre l’extrémité distale et l’extrémité proximale et comprenant une anse diathermique (110) au niveau de l’extrémité distale ; un moyen de commande fonctionnellement couplé au fil au niveau de l’extrémité proximale ; le moyen de commande étant configuré pour faire coulisser le fil de sorte que l'anse diathermique (110) s’étend hors du tube externe au niveau de l’extrémité distale dans un état ouvert pour mettre en place l'anse autour du polype ; le tube externe comportant en outre un moyen de coupe à l’extrémité distale configuré pour racler le polype, le moyen de commande étant en outre configuré pour, lorsque l'anse diathermique est dans l’état ouvert, faire coulisser (203) le moyen de coupe par rapport au tube externe vers le polype pour l'enlever.
