A treatment tool for operation comprises an insertion section (3) inserted into a living body, an operating section (5) including a fixed handle (6) removably connected to the base end side of the insertion section and a movable handle (77) adapted to operate with respect to the fixed handle, and a treatment section drive unit (2) including a treatment section operable and arranged at the forward end side of the insertion section, a drive unit (23) for driving the treatment section and a drive shaft (24) for connecting the drive unit to the operating section and transmitting the operating force of the operating section to the drive unit for operating the treatment section. An engaging section (121) is arranged at the forward end side of the fixed handle, and an engaging/disengaging member (111) is arranged at the base end of the insertion section and is adapted to engage the engaging section as required. A biasing member 108 is provided for energizing the disengaging/engaging member toward the position of engagement between the engaging/disengaging member and the engaging section.
