Abstract:
A medical device includes a shaft portion with a hollow shape and inflected portions or an exposed portion. The shaft portion is inserted into a cortical bone or penetrates through the cortical bone and is inserted to a position reaching a cancellous bone at an inner side of the cortical bone. The inflected portions are inflected to radial direction outer sides from one end portion of an axial direction of the shaft portion, and are exposed at a surface of the cortical bone. The exposed portion includes a portion that extends to the radial direction outer side from the one end portion of the axial direction of the shaft portion, and is exposed at the surface of the cortical bone.
