Abstract: A biopsy system includes an endoscope having an insertion portion provided with a channel and an active bending section disposed in part of the insertion portion, and a treatment tool. The treatment tool has a sheath capable of being inserted into the channel and a needle tube disposed inside the sheath. The sheath has a distal tube portion including a distal end of the sheath and a proximal tube portion fixed to a proximal end of the distal tube portion and less flexible than the distal tube portion. A connecting portion acting as a boundary portion between the distal tube portion and the proximal tube portion is placed in a proximal side relative to a proximal end of a bending section in a positional relationship in which the distal end of the sheath protrudes from a distal end of the channel and is optically observable by the endoscope.

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: An endoscopic treatment tool includes a sheath; a treatment portion capable of protruding and retracting from a distal end of the sheath; a manipulation main body; a slider which advances and retracts in a longitudinal axis direction to cause the treatment portion to protrude and retract from the sheath; a first locking mechanism which locks the slider at a position at which the distal end of the treatment portion is accommodated in the sheath in accordance with a retracting manipulation of the slider; a second locking mechanism provided at further distal side than the first locking mechanism and restricts advance of the slider by being locked to the manipulation main body; a fixing mechanism provided in the second locking mechanism and fixed to the manipulation main body by sliding; and a restricting portion which restricts fixing of the fixing mechanism to the manipulation main body.

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.
