PROBLEM TO BE SOLVED: To provide an instrument by which the two jaws and, if present, the knife are guided with great precision.SOLUTION: An instrument (10) having a tool (15) of a particularly simple design comprises jaws (16 and 17) with jaw supports (46) supported by spaced-apart hinges on a shared socket part 18. Hinge axes (27 and 28) of the hinges are oriented parallel relative to each other and are at a distance from each other. A slit (24) for precisely guiding a knife (25) may be provided between the two. The jaw supports (46) of the jaws (16 and 17) are guided in their own hinges with minimal play and hence in a precise manner. They are held against each other by transverse interlocking means (37), thereby ensuring a simple assembly and precise guiding. |
