The instrument for insertion of intervertebral disk professional thesis and execution example of method are offered. As for the instrument, the angular regulator which is used in order to adjust the angle which is formed at least two sides and, at least one upper plate (17) with, at least one lower part plate (18) with, at least one holder (100) with, the cage and the insertion axis which demarcate the insertion axis for professional thesis (X) with the front and back arrow condition axis (S) with by (12) with the guide whom it possesses the size which maintains the gap with (1), and the superior vertebral bone and the subordinate vertebral bone one separator (10) it includes at least. The method of transplanting professional thesis making use of the instrument which is disclosed, the pin positioning step and measure the size of the between cavity step and adjust the angular regulator step and the guide who (2) are transplanted in the middle arrow condition axis of the vertebral bone, and the step which inserts professional thesis to the between cavity and, includes to the guide.椎間板プロテーゼの挿入用器具及び方法の実施例が提供される。器具は、少なくとも2つの側面と、少なくとも1つの上部プレート(17)と、少なくとも1つの下部プレート(18)と、少なくとも1つの保持具(100)と、プロテーゼに対する挿入軸を画定するケージと、挿入軸(X)と前後矢状軸(S)とによって形成される角度を調整するために用いられる角度調整器(12)とを有するガイド(1)、及び上位脊椎骨と下位脊椎骨との間の間隙を維持する大きさの少なくとも1つのセパレータ(10)を含む。開示された器具を用いてプロテーゼを移植する方法は、脊椎骨の正中矢状軸にピン(2)を移植するステップと、椎間腔の寸法を測定するステップと、角度調整器を調整するステップと、ガイドを位置決めしてガイドへかつ椎間腔へプロテーゼを挿入するステップと、を含む。
