ELECTRONIC ENDOSCOPE

摘要

PURPOSE:To provide an electronic endoscope with limited noise in the use of an electric scalpel. CONSTITUTION:An imaging optical system, a lighting optical system and a metal tip part 30 where a forceps port of the like is arranged at the tip of an electronic scope 10 are connected to a current feedback terminal of an electric scalpel provided on the electronic scope 10 electrically through a conductor 32. The metal tip part 30 is equipotential with the current feedback terminal and the metal tip part 30 achieves a shielding effect to noises of the electric scalpel.
