A treatment instrument comprising:
- a sheath capable of a bending operation;
- an arm section protruding from the tip of the flexible sheath and being capable of the bending operation;
- an operation stick allowing an operator to carry out the bending operation of the arm section;
- a first rotation mechanism which is joined to the operation stick and bends the arm section;
- a second rotation mechanism which is joined to the operation stick and bends the arm section;
- and
- a second rotation mechanism which is joined to the operation stick and bends the arm section in a direction substantially orthogonal to the direction of the arm section bent by the first rotation mechanism.
