骨采集装置
摘要：
本发明涉及一种骨采集装置，该骨采集装置包括：一个套管，该套管具有一个纵向轴线，该套管包括一个近端和一个远端；以及一个骨容器，该骨容器与该套管的近端是连通的；其中，该套管进一步包括(i)一个切削表面，该切削表面的位置在该远端处或其邻近处，该切削表面是以一个角度进行取向的，该角度相对于该套管的纵向轴线大于90度，(ii)一个通道，该通道在该套管的远端开放以允许所采集的骨从邻近该切削表面的位置通过该套管进入该骨容器，以及(iii)一个闭塞几何结构，该闭塞几何结构邻近部分地闭塞了该通道的该切削表面，并且其中所采集的骨从邻近该切削表面的一个位置移动通过该通道进入该骨容器。
摘要（英）：

Methods and devices for harvesting cancellous bone are disclosed. The bone-harvesting device may include a cannula and a bone receptacle in communication with the cannula, wherein the cannula including a cutting surface positioned at or adjacent the distal end, the cutting surface being oriented at an angle, the angle being greater than 90 degrees relative to the longitudinal axis of the cannula, and the harvested bone is adapted to move from a position adjacent to the cutting surface through the cannula into the bone receptacle. The cutting surface of the cannula may be positioned at or adjacent the distal end, and positioned at least in part radially outward of the outer face of the cannula. The cannula may include a cutting surface positioned at or adjacent the distal end and an occluding geometry that partially occludes the distal end of the cannula adjacent the cutting surface. In addition, a suction port may be provided in communication with the bone receptacle.
