    • A medical punch with a hollow shaft, a tool point that is positioned on the distal end of the shaft and includes a rigid cutting part and a cutting part that can slide with respect to the rigid cutting part, and with a handle positioned on the proximal end of the shaft, such that the displaceable cutting part and the handle are operatively connected with one another by a push/pull device that is displaceably mounted in the hollow shaft and an anti-tilt mechanism is positioned on the tool point to stabilize the cutting parts in their axially parallel alignment to one another. The rigid cutting part includes a sleeve-shaped proximal portion that encloses the displaceable cutting part and a distal punch portion configured as a single unit with the sleeve-shaped portion and that the rigid cutting part should be detachably connected with the hollow shaft by a coupling mechanism formed on the sleeve-shaped portion.
    • 具有空心轴的医用冲头,位于轴的远端上的工具点,其包括可相对于刚性切削部分滑动的刚性切削部分和切削部分,以及位于近端 使得可移动的切割部分和手柄通过可移动地安装在中空轴中的推/拉装置彼此操作地连接,并且防倾斜机构定位在工具点上以稳定切割 部件彼此轴向平行对准。 刚性切割部分包括套筒形近端部分,其包围可移动切割部分和远侧冲头部分,该远端冲头部分构造为具有套筒形部分的单个单元,并且刚性切割部分应通过联接器与中空轴可拆卸地连接 机构形成在套筒形部分上。

    • A medical instrument has a cannula, a seal disposed in the cannula. An expansion device serves for expanding the opening in the seal for guiding shafts of other instruments of greater diameter in a sealed manner through the expanded opening. The expansion device has an expansion cone with a plurality of slats mounted pivotably on an annular body at a first end thereof, a second end of the slats, being connected to the seal in an area of the opening. The slats can either be connected at its first ends to the annular body via spherical heads engaged into corresponding openings in the annular body or the slats are connected at their ends via film hinges to the annular body.
    • 医疗器具具有插管,设置在套管中的密封件。 膨胀装置用于扩大密封件中的开口,用于通过膨胀的开口以密封的方式引导具有较大直径的其它仪器的轴。 膨胀装置具有膨胀锥体,多个板条在其第一端处可旋转地安装在环形主体上,板条的第二端在开口的区域中连接到密封件。 板条可以通过与环形体接合到相应开口中的球形头部在其第一端连接到环形体,或者板条通过薄膜铰链连接到环形体。
