    • A medical instrument with a hollow shaft having at its proximal end a handle consisting of at least two gripping members and at its distal end a tool consisting of at lest two jaw members, where at least one jaw member of the tool is adjustable in relation to the at least one other jaw member of the tool for purposes of opening and closing by means of one rotatably shaped gripping member of the handle, and the at least one adjustable jaw member and the corresponding gripping member of the handle that serves to adjust the jaw member are connected to one another by means of two push-pull rods. In order to create a medical instrument that ensures a constantly sufficient transmission of power, it is proposed with the invention that the two push/pull rods are secured on contact points at intervals from one another above and below the pivot point of the adjustable jaw member on this jaw member in such a way that two straight lines each extending from the pivot point through one of the contact points form an angle (alpha+beta) of 110 to 160 degrees.

    • The invention relates to a medical instrument with a hollow shaft, a handle, and a tool, where at least one jaw member of the tool can be rotated in relation to the at least one other jaw member of the tool for purposes of opening and closing by means of one rotatably configured gripping member of the handle, and the rotatable jaw member and the gripping member of the handle that serves to rotate are connected to one another by means of a push pin installed in the hollow shaft. To create a simple construction ensuring the best possible power transmission along with a good cutting sensation for the operator, a rigid casing can be inserted into the push pin, at least partly in form-locking connection, which casing in turn can be inserted, at least partly in form-locking connection, into the hollow shaft and the push pin is mounted in the casing so that it is at least partly rotation-resistant.
    • 本发明涉及具有中空轴,手柄和工具的医疗器械,其中工具的至少一个钳口构件相对于工具的至少一个其它钳口构件可旋转,用于打开和关闭 通过一个可旋转地配置的把手的夹持构件,并且用于旋转的可旋转夹爪构件和手柄的夹持构件通过安装在空心轴中的推动销彼此连接。 为了创建简单的结构,确保最佳的动力传递以及操作者的良好的切割感觉,刚性壳体可以插入到推销中,至少部分地形成锁定连接,该壳体又可以插入到 至少部分地形成锁定连接的中空轴,并且推销安装在壳体中,使得其至少部分地具有旋转阻力。

    • The invention relates to a medical instrument, comprising a shaft, the proximal end of which has a handle, with at least two grip pieces and the distal end of which has a tool, with at least two jaw pieces, whereby at least one jaw piece of the tool may be adjusted relative to the at least one other jaw piece for opening and closing, by means a grip piece on the handle, embodied so as to pivot. Each adjustable jaw piece and the corresponding grip piece in the handle, for adjusting the jaw piece, are connected to each other, by means of a pull-/push-rod and each adjustable jaw piece is connected to the pull-/push-rod, by means of a compensation lever. According to the invention, the best possible force transfer with a good cutting feel for the operator may be achieved, whereby the compensation lever is pivotably fixed on one end to the pull-/push-rod and displaceably mounted at the other end in a guide groove, formed in the adjustable jaw piece.
    • 本发明涉及一种医疗器械,其包括轴,其近端具有柄部,其具有至少两个夹持件,并且其远端具有工具,所述工具具有至少两个钳口件,由此至少一个钳口件 可以相对于至少一个其他钳口件来调节工具,以便打开和关闭手柄上的夹持件,从而枢转。 每个可调节的颚板和手柄中的相应把手,用于调节颚板,通过拉/推杆相互连接,每个可调节的颚片连接到拉/推杆 ,通过补偿杆。 根据本发明,可以实现对操作者具有良好切割感的最好的力传递,由此补偿杆在一端可枢转地固定到拉/推杆上,并且在另一端可移动地安装在导向件 凹槽,形成在可调颚板中。
