Abstract

Offenbart wird ein Elektrochirurgisches Instrument mit einem Maulteil aus gegeneinander bewegbaren Instrumentenbranchen, an deren einander zugewandten Seiten jeweils eine oder mehrere Elektrodenflächen angeordnet/ausgebildet sind, wobei die Bewegung der Instrumentenbranchen relativ zueinander durch zumindest einen auf proximale Endabschnitte der Instrumentenbranchen wirkenden proximalen Abstandshalter, zumindest einen auf einen medialen Abschnitt wirkenden medialen Abstandshalter und zumindest einen auf distale Endabschnitte der Instrumentenbranchen wirkenden distalen Abstandshalter begrenzbar ist. Erfindungsgemäß sind der proximale und/oder der distale Abstandshalter aus elektrisch nicht leitendem Material und der zumindest eine mediale Abstandshalter aus zumindest einer Elektrode aus einem elektrisch leitenden Material gefertigt sowie elektrisch leitend mit der Elektrode verbunden. Des Weiteren wirkt der zumindest eine mediale Abstandshalter mit einemlokalen Isolationsbauteil aus einem nicht leitenden Material zusammen, das in elektrisch isolierender Weise auf zumindest einer gegenüberliegenden Elektrode angeordnet ist.
