## Abstract

The endoscope treatment system includes an endoscope treatment tool that has an operating section including a distal end and a proximal end, and a sheath that is connected to the distal end of the operating section and is formed with a lumen into which the guide wire is capable of being inserted; a guide wire holder that has a tube member, in which the guide wire is accommodated, and that is circumferentially wound; and a fixing member that couples the operating section to the guide wire holder so that the distal end and the proximal end of the operating section are located outside the circumference of the guide wire holder.

## Claims

### Claim 1

An endoscope treatment system comprising:
an endoscope treatment tool that has (i) an operating section including a distal end and a proximal end, (ii) a sheath that is connected to the distal end of the operating section and is formed with a lumen into which a guide wire is capable of being inserted, and (iii) a first opening that is provided at the operating section so as to communicate with the lumen;
a guide wire holder that (i) has a tube member in which the guide wire is accommodated, (ii) includes a radially inner portion that is wound circumferentially and a radially outermost portion that is wound around the inner portion, the inner portion and the outermost portion being concentrically wound in a circular shape, and (iii) has an end portion with a second opening from which the guide wire is capable of protruding from the tube member;
a fixing member that couples the operating section to the guide wire holder so that the distal end and the proximal end of the operating section are located outside of the outermost portion; and
a holding fixture that holds the end portion of the guide wire holder so that the end portion is biased from the outermost portion toward the inner portion so as to overlap the inner portion and so that the second opening faces the first opening,
wherein the guide wire is exposed between the first opening and the second opening so as to be capable of being operated at a space further radially inward than the inner portion of the guide wire holder.

### Claim 2 (depends on 1)

The endoscope treatment system according to claim 1,
wherein the fixing member detachably couples the operating section to the guide wire holder.

### Claim 3 (depends on 2)

The endoscope treatment system described in claim 2,
wherein the fixing member couples the operating section to the guide wire holder so that the first opening is located inside the circumference of the guide wire holder.

### Claim 4 (depends on 3)

The endoscope treatment system according to claim 3,
wherein the operating section has:
a main body that is formed in a rod shape; and
a slider that is attached to the main body and is configured to slide along a longitudinal axis of the main body, and
wherein the fixing member couples the operating section to the guide wire holder so that the operating section is adjacent to the guide wire holder in a state where the longitudinal axis is turned to a tangential direction of the circumference of the guide wire holder.

### Claim 5 (depends on 4)

The endoscope treatment system according to claim 4,
wherein the holding fixture is attached to the tube member so as to be capable of switching between a state where the second opening of the tube member is located outside the circumference of the guide wire holder and a state where the second opening of the tube member is located inside the circumference of the guide wire holder.

### Claim 6 (depends on 5)

The endoscope treatment system according to claim 5,
wherein the operating section and the guide wire holder are detachably coupled by an engagement between (i) a concave portion provided in the fixing member and (ii) the tube member.

### Claim 7 (depends on 6)

The endoscope treatment system according to claim 6,
wherein the endoscope treatment tool and the guide wire holder are stored in a sterilizing pack in a state where the endoscope treatment tool and the guide wire holder are coupled by the fixing member.

### Claim 8 (depends on 2)

The endoscope treatment system according to claim 2,
wherein the operating section has:
a main body that is formed in a rod shape; and
a slider that is attached to the main body and is configured to slide along a longitudinal axis of the main body, and
wherein the fixing member couples the operating section to the guide wire holder so that the operating section is adjacent to the guide wire holder in a state where the longitudinal axis is turned to a tangential direction of the circumference of the guide wire holder.

### Claim 9 (depends on 1)

The endoscope treatment system according to claim 1,
wherein the fixing member couples the operating section to the guide wire holder so that the second opening is disposed closer to the inner portion of the guide wire holder than to the outermost portion.

### Claim 10 (depends on 9)

The endoscope treatment system according to claim 9,
wherein the holding fixture holds the end portion of the guide wire holder so that second opening is disposed within the circumference of the inner portion of the guide wire holder.

### Claim 11 (depends on 1)

The endoscope treatment system according to claim 1,
wherein the holding fixture comprises (i) a first part configured to hold a portion of the tube member so that the portion extends in a first direction, and (ii) a second part configured to hold another portion of the tube member so that the another portion extends in a second direction different from the first direction.

### Claim 12 (depends on 11)

The endoscope treatment system according to claim 11,
wherein the first part of the holding fixture comprises a plurality of concave portions, the axes of the concave portions extending in parallel directions, and
wherein the second part of the holding fixture comprises at least one additional concave portion, an axis of which extends in a direction non-parallel to the axes of the plurality of concave portions constituting the first part.

### Claim 13 (depends on 12)

The endoscope treatment system according to claim 12,
wherein the at least one additional concave portion of the second part holds the end portion of the guide wire holder.
