The good principles of all similar instruments have been combined in this snare, and their inherent defects have been obviated.
The wire is attached to a solid stylet, the objections to which are overcome by the powerful ratchet motion which draws it. A screw motion is also attached to the same stylet, thus enabling the operator to use a very slow-cutting snare, where hæmorrhage is feared, while the ratchet motion provides a rapid-cutting one where there is no reason to expect hæmorrhage.
The handle and ratchet motion may be detached at pleasure, leaving an instrument suitable for the slow strangulation of a very vascular growth.
The instrument has a straight tip for the nose and curved tips for reaching the larynx and naso-pharynx through the pharynx.
In curved canulas all attempts to use flexible stylets under severe traction are dangerous, as they must break sooner or later in making the
