Abstract
A puncture apparatus includes: a needle member having a tubular shape and comprising a flexible portion that is deformable; and a puncture assisting member that is movable or deformable in an axial direction of the needle member between: a restricting position in which the puncture assisting member is located outside the flexible portion of the needle member in a radial direction of the needle member, and thereby restricts deformation of the flexible portion, and a permissive position in which the puncture assisting member is not located outside the flexible portion in the radial direction, and thereby permits deformation of the flexible portion. The puncture assisting member is configured to move or deform from the restricting position to the permissive position in conjunction with an operation of inserting the flexible portion into a living body at a time of puncturing the living body with the needle member.
