Abstract: A treatment tool includes: a tubular insertion tube; an end effector that is provided at a distal end of the insertion tube and is bendable with respect to the insertion tube, the end effector being configured to apply treatment energy to a living tissue according to supplied power to treat the living tissue; a shaft body that is provided in the end effector and has an outer peripheral surface located on a circumference of a specific circle centered on a rotation axis when viewed from a direction along the rotation axis, the rotation axis allowing the end effector to be bent with respect to the insertion tube; and a wiring that is inserted through the insertion tube and serves as a supply path of the power, the shaft body including a passage through which the wiring is inserted.

Abstract: A treatment tool includes: an insertion tube; a distal end part that is provided at a distal end of the insertion tube; a shaft that is provided in the distal end part and that includes an outer circumferential surface; and a pair of transmitters each of which is inserted into the insertion tube and is fixed to the distal end part, the pair of transmitters being configured to transmit a drive force that causes the distal end part to flex with respect to the insertion tube, each transmitter being arranged along the outer circumferential surface with the shaft being sandwiched between the pair of transmitters and, on a distal end side with respect to the shaft, the pair of transmitters extending in a state of being separate from each other in a distance smaller than a diameter of the outer circumferential surface of the shaft.

Abstract: A treatment tool includes: a sheath; a treatment portion that is capable of treating a living tissue and is provided at a distal end of the sheath; a first driver and a second driver that are inserted in the sheath and are capable of driving the treatment portion; and a holder that is inserted in the sheath, and holds the first driver and the second driver. The holder includes a groove in which the first and second driver are inserted, and an intervening portion provided in the groove and arranged between the first driver and the second driver in a cross section perpendicular to a longitudinal direction of the groove that extends from a distal end to a proximal end of the holder.
