Accommodation tool
An accommodation tool is disclosed with which an operator can easily wind and accommodate a flexible medical elongated body. An accommodation tool winds and accommodates the flexible medical elongated body, for example, a guide wire. The accommodation tool has an inner wall, an outer wall, and an interlock wall. The guide wire is wound around the inner wall. The outer wall defines an accommodation space for accommodating the guide wire between the inner wall and the outer wall, and that is disposed further outward in a radial direction from a centroid of the accommodation tool than the inner wall. The interlock wall interlocks one end portion of the inner wall and one end portion of the outer wall with each other.

wherein each of the plurality of outer walls are arranged in the gap between the adjacent inner walls.
7. The accommodation tool according to claim 1 , further comprising:
a through-hole formed on the interlock wall.
8. The accommodation tool according to claim 1 , further comprising:
a space between the inner wall and the outer wall.
9. An accommodation tool which winds and accommodates a flexible medical elongated body, the tool comprising:
an inner wall around which the flexible medical elongated body is wound;
an outer wall;
an accommodation space configured to accommodate the flexible medical elongated body between the inner wall and the outer wall, and wherein the outer wall is disposed further outward in a radial direction from a centroid of the accommodation tool than the inner wall;
an interlock wall configured to interlock the inner wall to the outer wall;
wherein the inner wall extends in a direction intersecting the radial direction so as to be longer than the outer wall, and the inner wall tilting toward the outer wall;
the outer wall tilting toward the inner wall; and
a terminal of the inner wall is located further outward in the radial direction than a terminal of the outer wall.
10. The accommodation tool according to claim 9 , further comprising:
a wall surface of the inner wall being bent inward in the radial direction in a convex shape;
the interlock wall extending so as to be further separated from the inner wall or the outer wall than a portion on a line connecting the inner wall and the outer wall from each other; and
a wall surface of the outer wall being bent outward in the radial direction in a convex shape.
11. The accommodation tool according to claim 9 , wherein the outer wall comprises a plurality of outer walls, each of the plurality of outer walls having a gap between adjacent outer walls along a circumferential direction of the plurality of outer walls; and
wherein the inner wall comprises a plurality of the inner walls, each of the plurality of the inner walls having a gap between adjacent inner walls, and wherein the adjacent outer walls are arranged in the gap between the adjacent inner walls.
12. The accommodation tool according to claim 9 , further comprising:
a through-hole formed on the interlock wall; and
a space between the inner wall and the outer wall.
13. A method of winding a flexible medical body around an accommodation tool, the accommodation tool including an inner wall, an outer wall, an accommodation space configured to accommodate the flexible medical elongated body between the inner wall and the outer wall, and wherein the outer wall is disposed further outward in a radial direction from a centroid of the accommodation tool than the inner wall, and an interlock wall configured to interlock the inner wall to the outer wall, wherein the inner wall extends in a direction intersecting the radial direction so as to be longer than of the outer wall, and wherein the inner wall tilts toward the outer wall, the method comprising:
winding the flexible medical elongated body around the inner wall of the accommodation tool while pulling on the flexible elongated body.
14. The method according to claim 13 , comprising:
when starting to wind the flexible medical elongated body around the accommodation tool, pushing on an end portion of the flexible medical elongated body to prevent the movement of the end portion of the flexible medical elongated body.
15. The method according to claim 14 , comprising:
releasing the end portion of the flexible medical elongated body after winding the flexible medical elongated body around the inner wall of the accommodation tool.
16. The method according to claim 15 , wherein upon releasing the flexible medical elongated body, the flexible medical elongated body attempts to return to an original position due to an elastic force; and
forming an arc formed along a circumferential direction R in which a winding axis M is a central axis increases, and guiding the flexible medical elongated body to the outer wall side after being separated from the inner wall.
17. The method according to claim 16 , comprising:
gripping the accommodation tool and pushing on the outer wall of the accommodation tool; and
winding the flexible medical elongated body around the inner wall by pinching the flexible medical elongated body.
