A surgical implant-cutting instrument of the bipolar type, operated with direct current, is disclosed, with an instrument head which is located at the distal end of an instrument shank and which is provided for minimally invasive insertion of the instrument into a patients body, wherein at least two mutually opposing instrument branches, preferably of the linear type, are arranged on the instrument head and between them define a cutting gap for receiving an electrically conductive implant or implant section between them. According to the invention electrodes are formed on the mutually facing longitudinal sides of the branches or these are each equipped with at least one electrode, which electrodes are in turn shaped at their mutually facing longitudinal sides to form a cutting edge in order to effect a quasi linear or punctiform physical contact engagement with the electrically conductive implant or implant section for an electrical short circuit of the mutually opposing electrodes.
