Abstract

In order to allow a particularly small construction of a scissors-like tool for a surgical instrument with two interconnected arms which are pivotable elastically between a spread open position and a virtually closed position by engagement of a sleeve over the outside to a greater or lesser extent, this sleeve being axially displaceable relative to and engaging around the scissors-like tool, it is suggested that for forming the arms a rod consisting of elastic material have a diametric, front recess starting from its free end and followed by an additional, diametric, rear recess which is turned through 90.degree. about the longitudinal axis of the rod in relation to the diametric front recess, that the two diametric recesses be connected to one another by transverse recesses extending transversely to the longitudinal axis of the rod, these transverse recesses each extending over oppositely located quadrants of the cross section between the two diametric recesses whereas the two quadrants located therebetween have no such transverse recesses, and that the two arms be bent up permanently into the spread open position in the plane of the front, diametric recess. In addition, a process…
