In a medical liquid supply device, a control unit controls a liquid supply driver so that a liquid flows from the liquid supply driver in a liquid supply path regardless of whether a liquid-supply ON mode is selected. All of the liquid flowing from the liquid supply driver flows into a communication path when the liquid-supply ON mode is not selected. At least a part of the liquid flowing from the liquid supply driver does not flow into the communication path and is thereby supplied from a distal end of the liquid supply path when the liquid-supply ON mode is selected.

An ultrasound operation apparatus includes an ultrasound transducer; a drive section that drives the ultrasound transducer using a drive signal; a probe that has a proximal end section in which the ultrasound transducer is provided and a distal end section to which ultrasound vibrations are transmitted, and that performs treatment for living tissue by using ultrasound vibrations at the distal end section; a resonance frequency tracking section that drives so as to cause ultrasound vibrations to be generated at a resonance frequency; a detection section that detects a frequency component signal of a frequency component other than a resonance frequency of the drive signal; and a cavitation suppression control section that controls so as to suppress or eliminate cavitations according to the detection result.

An endoscope includes an image pickup unit having a solid-state image pickup device such as a CCD on a tip end side of an elongate insertion section. This image pickup unit constitutes a tip end side unit U and a rear end side unit U by conducting a surface treatment (metallization) to nonmetal members such as a tip end cover glass and a rear end cover glass and by airtight coupling surface-treated portions of the nonmetal members to metal members such as a tip end cover glass frame and a rear end cover glass frame by brazing using soldering, and constitutes an optical system unit by airtight coupling the metal members to metal members of an insulating unit U formed by airtight coupling a pipe member and a ring member to an insulating frame by welding.

Endoscope apparatus

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.
