骨锚固装置
摘要：
一种骨锚固装置，包括：骨锚固元件(2)，其具有待锚固于骨中的轴杆(3)和头部(4)；接收部件(5；500)，其用于接收待连接到骨锚固元件(2)的杆(100)，所述杆具有纵向轴线(L)；所述接收部件(5；500)形成为一体件并且包括：具有第一孔轴线(9)的第一开孔(8)、形状和尺寸制成为接收所述杆的凹槽(10)、具有第二孔轴线(13；130)的第二孔(12；120)，第二孔与第一孔(8)相通并且尺寸制成为接收头部(4)，轴杆(3)的一部分延伸穿过第二孔(12；120)，其中第二孔轴线(13；130)与由第一孔轴线(9)和所述杆的纵向轴线(L)限定的平面的夹角为大约90°；和压力元件(20)，其作用在头部(4)，以锁定所述头部相对于接收部件的位置。
摘要（英）：

A bone anchoring device is provided comprising: a bone anchoring element (2) having a shaft (3) to be anchored in the bone and a head (4); a receiving part (5; 500) for receiving a rod (100) to be connected to the bone anchoring element (2) the rod having a longitudinal axis (L), the receiving part (5; 500) being formed in one piece and having an open first bore (8) with a first bore axis (9), a recess (10) shaped and sized to receive the rod, a second bore (12; 120) having a second bore axis (13; 130), the second bore being in communication with the first bore (8) and being sized to receive the head (4) with a part of the shaft (3) extending through the second bore (12, 120), wherein the second bore axis (13; 130) includes an angle of approximately 90 DEG with a plane defined by the first bore axis (9) and the longitudinal axis (L) of the rod, and a pressure member (20) acting onto the head (4) to lock the position of the head relative to the receiving part.
