Abstract:
Hole punching pliers for punching holes in a skin protection plate for a stoma bag, the pliers comprising:a first plier part; an intermediate member; a second plier part pivotably connected to the first plier part directly and solely via the intermediate member wherein the first and second plier parts each have handle portions positioned on a first side of the intermediate member and working portions positioned opposite the handle portions; a rotationally symmetric punch having a circumferentially continuous cutting edge arranged in one plane substantially perpendicular to the axis of symmetry of the punch, the punch being attached to the working portion of the first plier part; and a counterplate having a symmetry axis and a generally planar face, the counterplate being attached to the working portion of the second plier part wherein at least one of the punch and the counterplate are pivotally attached to the working portion of the corresponding plier part so as to define at least a first lateral axis wherein the at least first lateral axis is arranged to be substantially perpendicular to the axes of symmetry of the punch and the counterplate and wherein operation of the handle portions of the first and second plier parts induces the punch and the counterplate into contact so as to punch a hole in the skin protection plate positioned therebetween, said punch being free to pivot during operation of said pliers.
