摘要： 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.

摘要： Provided is a high-frequency treatment tool. A positioning member that regulates movement of a second wire part within a sheath relative to a first wire part in a direction of a longitudinal axis of the second wire part is present in the sheath. In a state in which a folded part is located close to a distal end of the sheath, a loop formation part is fed from the distal end of the sheath with the second wire part fixed.

摘要： 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].
