An endoscope device has an endoscope provided with a front end portion where a nozzle and a sucking opening are formed. A first passage and a fluid supply pump are connected to the nozzle to supply fluid to it. A second passage and a suction pump are connected to the sucking opening. Connected to the first and second passages are a third passage and a pump for circulating the fluid in such a way that it is sucked through the sucking opening and jetted through the nozzle.

Endoscope device

At least one controlling unit of a controlling unit for controlling a bending driving motor bending driving a bendable portion, a controlling unit for controlling an advancing and retreating driving motor advancing and retreating moving an insert section and a controlling unit for controlling a rotating driving motor rotating driving the insert section and a camera controlling unit for processing a signal for an imaging device are made separate from each other so that such existing scope as an electronic scope or fiber scope fitted with a TV camera may be used.

Electronic endoscope system provided with a separate camera controlling

An endoscope apparatus comprises an elongate insert section including an observation window in the distal end portion and inserted into an object to be observed; an observation device for producing an endoscope image, the observation device including a focusing optical system which receives an incident light from the object through the observation window to focus the endoscope image; and a vibration device for vibrating at least a part of the insert section in a direction crossing the axial direction of the insert section, the vibration device including a vibration unit capable of vibrating in itself to vibrate at least the part of the insert section even under a condition that the insert section is not contact with the object.

Endoscope apparatus

The endoscope apparatus comprises an endoscope having an elongate insertable part having a bendable part and a driving apparatus for bending and driving the bendable part, a first bending controlling apparatus for controlling the driving apparatus and a second bending controlling apparatus for controlling the driving apparatus independently of the first bending controlling apparatus when the first bending controlling apparatus is controllable.

This solid state imaging apparatus is provided within the tip part of an insertable part of an endoscope and is provided with an image forming optical system for forming images. This image forming optical system forms an optical image on the imaging surface of a solid state imaging chip provided in the rear of this image forming optical system. This solid state imaging chip is affixed to a circuit substrate extending substantially at right angles with the imaging surface and electrically connected with the solid state imaging chip. This circuit substrate is connected with a signal cable transmitting input and output signals of the solid state imaging chip.
