Abstract
Provided is: an endoscopic device used for constructing an endoscopic system, which is simpler in structure and lower in cost as compared with conventional devices; and an endoscopic system using same. A hard-type laparoscopic device 111 has an optical viewing tube 121 equipped with observation optical systems 123, 125a-125d and an illumination optical system 122, the device being characterized in that a storage part 131 which houses a light source 141 which provides illumination light to the illumination optical system 122 and a gas cylinder 151 for supplying gas to insufflate the abdominal cavity is disposed in the optical viewing tube 121 in such a manner as to allow the optical viewing tube 121, the light source 141, and the gas cylinder 151 to be held together as a rigid integral unit.
