Provided is a processing tool for puncturing that is equipped with a needle tube the tip of which can be inserted into tissue, a cylindrical main body through which the needle tube is passed, and a slider to which the needle tube is fixed and which is disposed so as to be able to move in the axial direction of the needle tube relative to the main body. The slider and the main body are configured so that, by switching states of mutual engagement thereof, a selection can be made between a first state in which the slider can move in the axial direction relatively to the main body without rotating in the circumferential direction of the main body, and a second state in which the slider can rotate in the circumferential direction. |
