ABSTRACT:
In a surgical tubular-shafted instrument comprising a tubular shaft and a gripping part connected thereto, a tool pivotable about an axis of rotation extending transversely to the longitudinal axis of the shaft, and a push element in the shaft, the push element being movable by the gripping part in the longitudinal direction of the shaft and being in engagement with the tool by using projections and recesses arranged in spaced relation to the axis of rotation of the tool such that the tool is pivotable about its axis of rotation upon displacement of the push element, in order to make higher loading possible with small dimensions, it is proposed that a ring-shaped cage be arranged on the push element and surround the axis of rotation of the tool and the point of engagement of the projection and the recess, and the inside wall of the cage carry the projection or the recess of the push element.
