    • The invention relates to a tubular medical instrument having a hollow shaft, a handle positioned on the proximal end of the shaft and equipped with at least two gripping members, and at least one push-pull rod that is positioned in the hollow shaft and has on its distal end a tool consisting of at least two jaw members, wherein for opening and closing at least one jaw member of the tool, the push-pull rod can be coupled with at least one rotatable gripping member of the handle and wherein the push-pull rod and the handle can be detachably connected to one another by a coupling mechanism that is configured as at least one clamping device comprising at least one clamping claw characterized in that the at least one clamping claw can rotate in a guide track mounted between a closed position and an open installation position. To create a coupling mechanism that is easy to handle, it is proposed according to the invention that the at least one clamping claw is mounted in a guide track so that it can rotate between a closed clamping position and an open installation position.
    • 本发明涉及一种具有中空轴的管状医疗器械,位于轴的近端上的手柄,并配备有至少两个夹紧构件,以及至少一个推拉杆,其位于空心轴中并具有 其远端是由至少两个钳口构件组成的工具,其中用于打开和关闭工具的至少一个钳口构件,推拉杆可与手柄的至少一个可旋转夹持构件联接, 拉杆并且手柄可以通过联接机构可拆卸地彼此连接,所述联接机构构造成至少一个夹紧装置,该至少一个夹紧装置包括至少一个夹紧爪,其特征在于,所述至少一个夹爪可以安装在封闭的 位置和开放的安装位置。 为了创建易于处理的联接机构,根据本发明提出,至少一个夹爪安装在导轨中,使得其可以在闭合的夹紧位置和开放的安装位置之间旋转。
