SURGICAL NEEDLE SET AND METHOD FOR DETERMINING THE POSITION OF A SURGICAL INSTRUMENT

Particularly for automatic determination of the position of a Jamshidi needle, the invention proposes a surgical needle set (1) with a hollow needle (2) and an obturator, in which the obturator has, starting a finite distance from its distal tip, a cavity extending along the proximal direction, in which at least one proximal lateral outlet of the cavity is provided inside a grip part (3.1) of the obturator, and in which the cavity is connected to a passage of an adapter part (3.6.1) of an adapter, said passage extending at a finite angle relative to the longitudinal extent of the cavity. 特别是为了自动定位Jamshidi针，本发明提出一种具有空心针(2)和闭孔器的手术针套件(1)，其中所述闭孔器在与其远侧尖端间隔有限距离处开始具有在近侧方向上纵向延伸的空腔，在所述闭孔器的握持部(3.1)内设有所述空腔的至少一个近侧侧向出口，其中，所述空腔与接头的接头部件(3.6.1)的通道连接，所述通道以与所述空腔的纵向延伸成有限角度的方式延伸。
