The endoscope has a light guide fiber bundle over which illumination light is propagated. The battery-powered light source is freely detachably attached to the endoscope, and includes an illumination lamp and a battery. The illumination lamp supplies illumination light to the incidence end of the light guide fiber bundle on which illumination light falls. The battery serves as a power supply causing the illumination lamp to light. At least one of the endoscope and battery-powered light source has an indication unit for notifying a user of the amount of electrical energy contained in the battery.

Endoscope device and operation apparatus

According to a remote operation support system, a physician present in a remote place can view endoscopic images displayed in an operating room over a communication line, and change an image area or a viewing direction represented by endoscopic images in a desired manner by performing manipulations. The physician present in the remote place can thus support an operator present in the operating room. An endoscope system installed in the operating room and a remote control system installed in a control room located in the remote place are linked using a public communication line. The endoscope system has a signal transmission apparatus installed in the operating room. The signal transmission apparatus in the operating room converts a video signal and a control signal or patient data, which are produced by a CCU and a system controller respectively, and outputs resultant signals over the public line. The remote control system has a signal transmission apparatus installed in the control room. The signal transmission apparatus in the control room is connected on the public line and converts the transmitted signals into the original signals. A second monitor and a remote controller are connected to the transmission apparatus.

Remote operation support system and method

A plurality of pieces of medical equipment each of which includes a microcomputer and has a program used to control the microcomputer stored in a reproqrammable storage device such as an EEPROM is linked to a remote computer over a communication line. Using a rewriting/updating program sent from the computer, each piece of medical equipment rewrites or updates the program stored in the storage device. When a plurality of programs is stored, if one of the programs is rewritten or updated abnormally, the other program is used to activate medical equipment.
