An endoscope system having a cover type endoscope provided with an elongate inserting section having therein an observation device and an illuminating device and bulge portions formed on the outer periphery at the side of a forwardmost end of the inserting section; and an endoscope cover having an endoscope inserting passage for covering and protecting the inserting section. The endoscope inserting passage receives the inserting section using the bulge portions as a guide. The bulge portions project more than the outer periphery of the inserting section.

Endoscope system having an endoscope capable of being guided into an

An endoscope system provided with an electronic or optical endoscope is provided therein with an illuminating optical system, an observation optical system, a flow passage system and a forceps channel. Cleaning and disinfection operations are performed on the endoscope so that the endoscope is reusable. An electronic or optical cover type endoscope is provided therein with an illuminating optical system and an observation optical system. The cover type endoscope is used with an endoscope cover having a flow passage system and a forceps channel mounted on the cover type endoscope. The endoscope cover is discarded and replaced whereby the cover type endoscope is reused. Peripheral equipment for endoscope inspection used in combination with the endoscopes is capable of being selectively connected to any of the endoscopes.

Endoscope system including both reusable-type and cover-type endoscopes

An endoscope cover apparatus including a joint portion for fixing a control portion of an endoscope disposed adjacent to an operator, and extending insertion-portion cover disposed in front of the joint portion, a cover leading member disposed in the leading portion of the insertion-portion cover, a first tubular passage member passing through the cover-type endoscope from the joint portion to the cover leading member to continuously connect opening portions respectively formed in the cover leading member and the joint portion, and a second tubular passage member for continuously connecting the tubular passage of the joint portion to an external device.

Endoscope cover apparatus for use with cover-type endoscope and

A cover-type endoscope apparatus comprises a cover and a covering endoscope used by being inserted into the cover. At least one hand-side tube line of tube lines forming a plurality of channels provided in the cover has a thickness larger than a thickness of an inserting-side tube line.

Cover-type endoscope apparatus

A method for parsing of a language defined by context free grammar includes the steps of extracting groups corresponding to words of a sentence in an order of word arrangement of the sentence, each of the groups being formed by a terminal symbol, a start-position number, and an end-position number of a corresponding one of the words; creating a state list by using the groups, the context free grammar, and an LR table derived from the context free grammar, the state list corresponding to position numbers indicating positions of the words and including state numbers indicating state of the parsing; and carrying out the parsing while creating the state list.

Language parsing device and method for same

An covered endoscope type of endoscopic apparatus has a covered endoscope and a cover for covering the covered endoscope. The covered endoscope has an elongated flexible inserted portion, an operated portion formed on the base end side of the inserted portion, and a universal cord extending from a side portion of the operated portion. The cover is formed of an inserted portion cover member, an operated portion cover member and a cord cover which cover the inserted portion, the operated portion and the universal cord of the covered endoscope, respectively. An operated endoscope portion fixation mouth member having a forceps inlet and an expansion tube mouth to which an expansion tube provided on an expander is connected is provided at a base end of the inserted portion cover member. An air supply tube, a water supply tube and an aspiration tube are inserted through the inserted portion cover member, the operated portion cover member and the cord cover. The overall length of the aspiration tube, the air supply tube and the water supply tube of the cover is set so as to be greater than the sum of the lengths of the inserted portion, operated portion and universal cord of the covered endoscope.

Endoscopic apparatus using a covered type endoscope fitted in an

A cover type endoscope apparatus including an endoscope cover and an endoscope to be covered which is used by being inserted into the endoscope cover. The endoscope cover can be used in common for covering a plurality of endoscopes to be covered having different lengths without changing the length of the cover.

Cover type endoscope apparatus

An endoscope cover with a channel covers at least an inserted portion of an endoscope. The endoscope cover has a treatment tool channel into which a treatment tool is inserted and incorporates a treatment tool raising device for moving, to a predetermined position, the treatment tool inserted into the treatment tool channel and protruding from a distal end portion of the treatment tool channel. The endoscope cover includes an endoscope operating portion fixing port portion provided at a proximal end portion of an inserted portion covering portion which covers the inserted portion of the endoscope. The port portion fixes an operating portion of the endoscope inserted into the inserted portion covering portion. A treatment tool raising device operating member connected to the treatment tool raising device for operating the treatment tool raising device is disposed in the endoscope operating portion fixing port portion.

Endoscope cover with channel

A cover type endoscope apparatus includes a cover, a covered endoscope which is inserted into this cover and used, and a cover holder for holding various peripheral units connected to the covered endoscope and the cover, wherein an indication device for indicating whether or not an apparatus should handle a clean area in a sterile state or other area is provided in each of the components.

The present invention relates to an endoscope cover-sheathed endoscope having an endoscope in which an insertional part is extending from an operational part, and an endoscope cover made up of an insertional part cover, an operational part cover, and a universal cord cover, which shield the endoscope and are concatenated in that order from the distal end of the endoscope. The operational part cover overlaps and shields the margin of the insertional part cover, while the operational part cover overlaps and shields the margin of the universal cord cover. The endoscope will not therefore be bared.
