Abstract

In a surgical instrument, in particular, a tubular-shafted instrument, comprising two grips pivotally movable relative to one another for moving two tools movable relative to one another, and a releasable locking mechanism for securing the grips in various positions moved towards one another against movement away from one another, in order to make operation with one hand possible, it is proposed that a locking lever be pivotally mounted on one grip, the free end of the locking lever being longitudinally displaceable along a displacement path on the other grip upon pivotal movement of the grips, that a toothing be arranged along the displacement path of the free end for engagement with a toothing at the free end of the locking lever such that an opening movement of the grips is prevented, and that for release of the engagement of the two toothings the displacement path be adjustable such that the toothings disengage.
