    • A biopsy needle has a forward needle opening that can be closed off with a trap door. The trap door is pivotally mounted to a flat top surface inside the needle opening. As the needle is extracted, a forward blade of the trap door cuts into the biopsy tissue and the trap door pivots about a pivot axis extending transversely to a longitudinal direction of the needle. The trap door is configured to match a contour of the top surface and an adjacent curve of the needle opening to maintain the needle substantially open when the trap door is in the open position and to close the forward needle opening when the trap door is in the closed position and the biopsy tissue specimen is entrapped inside the needle.
    • 活检针具有可以用收集门封闭的向前针开口。 收集门可枢转地安装在针头开口内的平坦的顶面上。 当针被提取时,捕获门的前向叶片切入活检组织,并且捕获门围绕横向于针的纵向方向延伸的枢转轴线枢转。 捕集器门被配置成匹配顶部表面的轮廓和针开口的相邻曲线,以在陷阱门处于打开位置时保持针基本上打开,并且当陷阱门处于打开位置时关闭向前针开口 闭合位置,活检组织样本被夹在针内。

    • A motorcycle towing device includes a substantially vertical member and a substantially horizontal member being interconnected for supporting a motorcycle wheel. A support column is pivotably and releasably mounted on at least one of the members, such as with a removable hinge pin passing through holes in the support column and in brackets on the support column. A draw bar is connected to the support column for insertion into a receiver mounted on a vehicle and at least one shim is disposed between the draw bar and the receiver.
    • 摩托车牵引装置包括大致垂直的构件和互连的用于支撑摩托车车轮的大致水平的构件。 支撑柱可枢转地和可释放地安装在至少一个构件上,例如通过可移动的铰链销穿过支撑柱中的孔和支撑柱上的支架中。 拉杆连接到支撑柱,用于插入安装在车辆上的接收器中,并且至少一个垫片设置在拉杆和接收器之间。
