Abstract
A medical instrument, which is capable of holding a wire, includes: a sheath which has a center axis in a longitudinal direction from a distal end toward a proximal end thereof and includes in a distal end surface of the distal end a first contact area capable of being in contact with the wire and a second contact area coming in contact with the wire and provided on a proximal end side beyond the distal end with respect to the first contact area; and a holding portion which is advanceable and retractable in a lumen of the sheath and is retracted into the lumen of the sheath so that the wire is pressed to the first contact area and the second contact area and the holding portion holds the wire.

A medical instrument which is capable of holding a wire, comprising:
- a sheath which has a center axis in a longitudinal direction from a distal end thereof toward a proximal end thereof and includes in a distal end surface of the distal end a first contact area capable of being in contact with the wire and a second contact area coming in contact with the wire and provided on a proximal end side beyond the distal end with respect to the first contact area;
- and
- a holding portion which is advanceable and retractable in a lumen of the sheath and is retracted into the lumen of the sheath so that the wire is pressed to the first and second contact areas and the holding portion holds the wire,
- wherein an inclined surface which is inclined with respect to the center axis is formed at the distal end of the sheath, and at least one of the first contact area and the second contact area is provided at the inclined surface.
A medical instrument which is capable of holding a wire, comprising:
- a sheath which has a center axis in a longitudinal direction from a distal end thereof toward a proximal end thereof and includes in a distal end surface of the distal end a first contact area capable of being in contact with the wire and a second contact area coming in contact with the wire and provided on a proximal end side beyond the distal end with respect to the first contact area;
- and
- a holding portion which is advanceable and retractable in a lumen of the sheath and is retracted into the lumen of the sheath so that the wire is pressed to the first contact area and the second contact area and the holding portion holds the wire,
- wherein a cut-out portion which is cut out along the center axis is formed in the distal end of the sheath, and at least one of the first contact area and the second contact area is provided at a bottom surface of the cut-out portion.

- a holding portion which is advanceable and retractable in a lumen of the sheath and is retracted into the lumen of the sheath so that the wire is pressed to the first contact area and the second contact area and the holding portion holds the wire;
- and
- a lumen which is formed along the lumen of the sheath and is different from the lumen of the sheath.
