Packaging material for endoscopic treatment system and endoscope system

1. A packaging material packaging an endoscopic treatment system to be used in combination with an endoscope,

wherein the endoscopic treatment system includes:

an endoscopic treatment device includes:

an operating part with a distal end and a proximal end; and

a sheath which is connected to the distal end of the operating part and in which a lumen is formed; and

a guide wire which has a coated region applied with coating at a distal end of the guide wire and is inserted into the lumen of the sheath, and

wherein the packaging material includes:

a tray which holds a distal end side of the sheath in a state where a predetermined positional relationship between the sheath and the guide wire is held and the coated region of the guide wire is exposed from a distal end of the sheath;

wherein the tray includes:

a sheath holding part configured to hold the sheath; and

a wire storage part placed closer to the distal end side of the sheath than the sheath holding part, and configured to hold the full length of the coated region of the guide wire exposed from the distal end of the sheath straight,

wherein the sheath holding part includes:

an introduction part positioned at a proximal end of the sheath; and

a bottom surface positioned closer to the distal end of the sheath than the introduction part, wherein the bottom surface is positioned lower than the introduction part in a depth direction of the tray.

2. The packaging material according to claim 1 ,

wherein the sheath holding part has a curved shape which holds the distal end side of the sheath in a curved state, and

wherein the introduction part is positioned at a proximal end side of the curved shape.

3. The packaging material according to claim 2 ,

wherein the wire storage part is arranged so as to intersect, with a part of the sheath that is closer to the proximal end of the sheath than the sheath holding part of the sheath, and

wherein the sheath holding part holds the sheath so that the part of the sheath passes through over the guide wire that is stored in the wire storage part.

4. The packaging material according to claim 1 ,

wherein the tray includes:

a locking portion positioned closer to the proximal end of the sheath than the introduction part,

wherein the locking portion is configured to lock the sheath so as to be detachable with respect to the depth direction of the tray.

5. The packaging material according to claim 4 ,

wherein the tray includes:

a distal end guide wall which extends from the sheath holding part and against which a distal end portion of the sheath is pressed by a restoring force to bring the sheath into a linear state,

wherein the wire storage part includes a pair of wall surfaces which extend from the distal end guide wall and gradually increases in an interval between the pair of wall surfaces according to the distance from the distal end guide wall, and

wherein the pair of wall surfaces are separated from the guide wire in a state where the distal end of the guide wire is arranged between the pair of wall surfaces.

6. The packaging material according to claim 5 ,

wherein the distal end guide wall has a planar shape configured to hold the distal end portion of the sheath straight.

7. The packaging material according to claim 6 ,

wherein the wire storage part is formed of polypropylene.

8. The packaging material according to claim 7 ,

wherein the pair of wall surfaces extend from the bottom surface, and

wherein the packaging material further includes a lid member which has a top surface portion facing the bottom surface.

9. The packaging material according to claim 8 ,

wherein the endoscopic treatment system further includes:

a guide wire holder in which a tube body in which the guide wire is stored is wound circumferentially; and

a fixing member configured to connect the operating part to the guide wire holder such that the distal end and the proximal end of the operating part of the endoscopic treatment device are placed outside the circumference of the guide wire holder, and

wherein the tray is configured to support the operating part and the guide wire holder in a state where a predetermined positional relationship between the operating part and the guide wire holder is held.

10. The packaging material according to claim 9 ,

wherein the sheath holding part and the wire storage part are positioned inside of a circumference of a circle of the guide wire holder in a state where the tray holds the operating part and the guide wire holder.
