- the grasping forceps 400 Since the major axis direction of the second insertion passage 120 at the distal end is different from the major axis direction of the first insertion passage 110, the grasping forceps 400 has the overtube 100 as shown by a black arrow in FIG. It protrudes toward the outer side rather than the outer periphery. As is clear from FIG. 3B, the distance L between the tips of the grasping forceps 400 and the electric knife 300 (indicated by a double-headed arrow in the figure) can be adjusted according to the length for projecting them. It is.

- the grasping forceps 400 protrude outward as described above, in other words, outward from the center of the surgical field, the digestive tract surface S grasped by the grasping forceps 400 is diagonally rightward in FIG. Can be pulled upward. Therefore, tension can be applied to the tumor T with the electric knife 310 by applying tension on substantially the same plane as the visual field. The degree of tension can be easily adjusted by adjusting the length of protrusion of the grasping forceps 400. In addition, the distance between the treatment portion by the electric knife 310 and the holding portion by the grasping forceps 400 can be sufficiently secured, and the work area can be visually recognized by the electric knife 310.
- the direction of tension that can be applied by the grasping forceps 400 is perpendicular to the visual field plane.
- Direction. Specifically, since the grasped gastrointestinal tract surface S is pulled in the front-rear direction (that is, the front direction and the back direction) with respect to the visual field surface, the visible region for performing the treatment with the electric knife 310 is narrow. Become. If a grasping forceps having a deflectable or steerable structure is used, the digestive tract surface S can be pulled in any direction on the same plane as the visual field. However, the structure and operation of the grasping forceps are both complex. On the other hand, as described above, when the endoscope overtube 100 is used, the length of the protrusion is simply adjusted using the grasping forceps having a simple structure on the digestive tract surface S. The tension appropriate for the treatment can be obtained.
- the endoscope overtube of the present invention does not require an endoscope or treatment instrument having a special structure, and can be used with a commonly used endoscope and a treatment instrument having a simple structure.
- the tissue can be grasped and incised under appropriate tension. Therefore, technically difficult techniques such as EMR, ESD, EAM, EVL, and NOTES are used.
