It is drilling the hole in the correct orientation in the correct position the screw guide template system screw guide template that can be drilling a hole in the correct orientation in the correct position (30) and (20), of the piercing member the piercing member drilling method capable, as well as to provide a spinal fusion surgery method that can puncture in the exact direction to the exact position spinal fixation screw. Screw guide template (20), and a (22) contact surface that is brought into close contact with the piercing member (21), through holes having one opening and (23a) to the densely adhesive surface, densely wear surfaces, the perforation It has a shape of the relationship of the male and female (31) surface shape including (32) perforation of intended location of the member, when it is brought into close contact with the drilling of intended location of the piercing member densely adhesive surface, the above opening perforations of intended location of the piercing member overlap, and is formed to be coaxial with the bore plan is the through hole, drilled by the drilling means.被穿孔部材(30)に正確な位置に正確な方向で孔を穿つことができるスクリューガイドテンプレート(20)、及びスクリューガイドテンプレートシステム、被穿孔部材の正確な位置に正確な方向で孔を穿つことができる穿孔方法、並びに、脊椎固定スクリューを正確な位置に正確な方向で刺入できる脊椎固定手術方法を提供する。スクリューガイドテンプレート(20)は、被穿孔部材に密着させる密着面(21)と、該密着面に一方の開口部(23a)を有する貫通孔(22)とを備え、該密着面が、被穿孔部材の穿孔予定箇所(32)を含む表面形状(31)と雄雌の関係の形状を備えており、該密着面を被穿孔部材の穿孔予定箇所に密着させた際に、上記開口部と被穿孔部材の穿孔予定箇所とが重なり、上記貫通孔が、穿孔手段によって穿つ予定の孔と同軸になるように形成されている。
