Abstract

A puncture instrument (10) includes a movable body (14) movably disposed in a case (12), and a needle unit (16) held by the movable body (14) and having a needle (60). When a distal end face (40a) of the movable body (14) is brought into abutment against a region to be punctured and the case (12) is advanced toward the region to be punctured, the case (12) is advanced together with the needle unit (16), and the tip end of the needle (60) becomes protruded from the movable body (14) and punctures the region to be punctured. An arm (66) of the needle unit (16) is abutted against and turned about a fulcrum member (52), thereby withdrawing the needle (60) rearwardly.
