A surgical snare instrument includes a first handle (26) capable of controlling the rotational position of the snare (24), and a second handle (28) adapted to control the opening and closing of the snare (24) and cauterization. The first handle (26) serves as a grippable element on the sheath (12) and contains a system which rotates the shaft (18), and consequently the snare (24), so that when the physician grips the first handle (26), the physician is capable of steering the snare (24) by operating the first handle (26). In addition, the physician is also capable of positioning the entire sheath (12) relative to the endoscope by sliding the sheath (12) into and out of the working channel of the endoscope.
L'invention concerne un instrument de polypectomie à anse diathermique, qui comporte une première poignée (26) permettant de commander la position en rotation de l'anse diathermique (24), et une deuxième poignée (28) conçue pour commander l'ouverture et la fermeture de l'anse diathermique (24) et la cautérisation. La première poignée (26) sert d'élément pouvant être saisi sur la gaine (12), et contient un système qui fait tourner la tige (18), et par conséquent l'anse diathermique (24), de sorte que lorsque le chirurgien saisit la première poignée (26), il peut diriger l'anse diathermique (24) en actionnant la première poignée (26). De plus, le chirurgien peut également positionner la gaine entière (12) par rapport à l'endoscope en faisant glisser la gaine (12) à l'intérieur ou hors du canal biopsique de l'endoscope.
