ABSTRACT:
A noise suppressor is provided for an electronic endoscope which incorporates a diathermic cutter or an ultrasonic diagnosis system. The electronic endoscope utilizes a solid-state camera, and in order to prevent noises from being superimposed upon the signal fed to an image display, a transmission line which transmits a high frequency current to the diathermic cutter or a transmission line which transmits an ultrasonic signal to or receives an ultrasonic signal from an ultrasonic probe is shielded by a conductor member. In particular, for a transmission line which conveys the high frequency current, impedance regulating means is connected therewith in order to prevent the high frequency current from leaking through a distributed capacitance between the transmission line and the conductor member. Alternatively, a narrow bandpass filter may be provided which limits the frequency band of the high frequency current. A coaxial cable may be used in which both the transmission line and the conductor member are formed of conductive rubber.
