摘要： An endoscope is configured such that the position of the distal end of a treatment tool can be fine-adjusted when inserting and withdrawing the treatment tool into/from a treatment tool channel in the endoscope. For example, the treatment tool is inserted into the treatment tool channel of the endoscope and moved forward by a driving motor. When the distal end of the treatment tool projects from the treatment tool channel at the distal end of the endoscope, the forward movement is stopped, and the treatment tool is moved forward by manual operation. A method of manual operation includes the steps of rotating a dial and moving the treatment tool forward slowly. When in manual operation, the treatment tool is preferably released from any static torque of the motor.
