    Abstract: An ultrasonic biopsy needle includes a sheath inserted through a channel of an ultrasonic endoscope; a needle tube which is inserted through the sheath and capable of advancing and retracting inside the sheath; and an operation portion which is connected to a proximal end of the sheath and is provided to advance and retract. The sheath includes an extension limiting portion that is positioned more distal than a proximal end of a bending portion of the ultrasonic endoscope. The extension limiting portion is formed of a metal coil, the ratio of the inner diameter of the channel to the outer diameter of the coil is in a range from 1.0:0.84 to 1.0:0.96, the initial tension of the coil is equal to or greater than 2.0 [N] or greater, and extension of the sheath caused by the forward and backward movement of the needle tube is limited.

    Abstract: An ultrasonic biopsy needle includes a sheath inserted through a channel of an ultrasonic endoscope; a needle tube which is inserted through the sheath and capable of advancing and retracting in the sheath; and an operation portion which is connected to a proximal end of the sheath and is provided to advance and retract the needle tube. The sheath includes a meandering suppressing portion positioned more proximal than a proximal end of a bending portion of the ultrasonic endoscope when a distal end of the sheath is positioned in a visual field of an optical image-capturing mechanism of the ultrasonic endoscope. The meandering suppressing portion is formed of a metal coil, the ratio of the inner diameter of the channel to the outer diameter of the coil is in a range from 1.0:0.66 to 1.0:0.84, and the initial tension of the coil is equal to or greater than 5.0 [N].

    Abstract: A treatment tool for an endoscope includes: a sheath; a balloon provided at a distal end of the sheath, and configured to be expandable from a folded initial shape to an unfolded inflated shape; an inner shaft configured to protrude from a distal end of the balloon through an inside of the balloon; a middle marker; and at least one or more positioning markers provided on the inner shaft independently of the middle marker. The balloon has a proximal end-side region, a distal end-side region, and a middle part. At least one of the positioning markers is positioned on the inner shaft at same a longitudinal position as the proximal end-side region.

    Abstract: An endoscope treatment tool includes: a clip unit having a clip main body which includes first and second arm portions, a pressing tube which is formed in a tube shape, a locking portion which protrudes from an inner circumferential surface of a proximal end of the pressing tube, and a locked portion which protrudes from the clip main body; a linear member connected to the clip unit; a sheath in which the linear member is inserted; and a fracture mechanism connected to a proximal end of the linear member. The fracture mechanism includes a first support member connected to the linear member, a second support member disposed on a proximal end side of the first support member, and a fracturable member disposed between the first support member and the second support member so as to connect the first support member and the second support member.
