Abstract
For annealing a proximal end portion of a needle material for a suture needle, an energy beam is applied to a proximal end face of the needle material. There can be used a common oscillator which emits a laser beam for forming a gut-mounting hole in the proximal end portion of the needle material, and also emits a laser beam for effecting the above annealing. In this case, a converter is used for changing a path of travel of the laser beam. Namely, for forming the mounting hole, the laser beam from the oscillator is supplied to the proximal end face of the needle material through a condenser lens. For effecting the annealing, the laser beam is smoothed by a smoothing member, and is applied to the proximal end face of the needle material. In the case where the common oscillator is used, the needle material may be moved along the axis of the needle material.
