ABSTRACT:
There is disclosed a system for creating holes in surgical needle materials, respectively. A large number of needle materials are held by a holder. An image of the proximal end faces of the needle materials is picked up by an image pickup device. A moving mechansim is operated in accordance with this image information so as to move at least one of a beam emitting device and the holder in a direction intersecting the axes of the needle materials and the axis of an energy beam to be emitted from the beam emitting device, so that the energy beam to be emitted can sequentially coincide with the axes of the needle materials. Then, the energy beam is sequentially applied to the proximal end faces of the needle materials to create the respective holes therein. When an electron beam is used as the energy beam, the electron beam is deflected by deflecting coils so that the electron beam can coincide with the axis of a selected one of the needle materials.
