<p>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.</p> |
