Abstract: An image recording apparatus includes a recording section, a storage section, and a control section. The recording section records an output video outputted from a first endoscope, an output video outputted from a PACS terminal, and an output video outputted from a second endoscope, and generates recording information including data of the output videos, to retain the generated recording information. The storage section stores display state information outputted from a display apparatus. The control section controls the recording section and the storage section, so as to generate the recording information by associating the data of the output videos with the display state information.

Abstract: A medical system includes: an endoscope including an insertion portion inserted into a subject, an image pickup device configured to output an image signal of the subject being arranged in the insertion portion; a video processor configured to process the image signal to generate image data; an insertion length acquisition apparatus configured to acquire information on an insertion length when the insertion portion of the endoscope is inserted into the subject; and an image recording apparatus including a storage device configured to record the image data as a moving image. The image recording apparatus includes an image generation apparatus configured to edit the moving image and generate a moving image for saving, based on the information on the insertion length supplied from the insertion length acquisition apparatus.

Abstract: A gas supply source for supplying gas and a channel along which the gas is supplied can be easily switched by providing an instrument channel for passing an endoscope treating tool, a gas and water supply channel for supplying carbon dioxide etc. to the inside of a body, a gas supply source for a visceral cavity capable of supplying gas at a predetermined pressure, a gas supply source for a lumen capable of supplying gas at an optional pressure, and a switch device for switching from any of and an instrument channel and a gas and water supply channel to any of the gas supply source for a visceral cavity and the gas supply source for a lumen.

Abstract: An over tube comprises an over tube body that has an inner diameter fitting over the outer diameter of an insertion part, and is flexible and expandable in the direction of the outer diameter, a gas supply port provided on the base end side of the over tube body, an expansion/contraction part that is formed integrally with the gas supply port, provided to communicate from the base end side to a predetermined position on a distal end side, and can expand in the direction of the outer diameter by injecting a gas from the gas supply port, and at least one channel that is provided between the inner and the outer diameters of the over tube body, and penetrates from the distal end of the over tube through the base end side.
