摘要:
An endoscope system including an endoscope having an insertion section which extends from a proximal end to a distal end and is inserted into a cavity under inspection and an operation section connected to the proximal end of the insertion section, and a protection cover including an insertion section inserting channel which extends from a proximal end to a distal end and into which said insertion section of the endoscope is insertable and a conduit channel which extends from the proximal end to the distal end, the improvement being characterized in that a distal end portion of the insertion section has a non-circular cross section such as a semicircular or oval cross section and a proximal end portion of the insertion section has a substantially circular cross section. A distal end member of the insertion section inserting channel has an accommodating portion which is a corresponding non-circular cross section.

An endoscope system detachably provided with a cover endoscope possible of being fitted with a cover and used by covering its outer surface with the cover and a coverless endoscope used without being fitted with the cover. A display range and a visual field range of an image that are obtained in the cover endoscope have substantially the same configurations as those of a display range and a visual field range of an image that are obtained in the coverless endoscope.

In an endoscope system including an endoscope having an insertion section insertable into a cavity under inspection and an operation section having at least one operation switch, said operation section being connected to a proximal end of said insertion section and a disposable protection cover having an insertion section cover for covering said insertion section of the endoscope and an operation section cover for covering said operation section of the endoscope, said insertion section cover includes a forceps channel through which existing forceps for use in ordinary without-cover endoscopes can be inserted. An inner diameter of the forceps channel is determined to be slightly larger than an outer diameter of most frequently used forceps or standard forceps whose number shows a peak in the outer diameter series of the forceps.

A package assembly for packaging an endoscope cover for covering the outer surface of the endoscope is disclosed. The package comprises a cover for an insertion tube section of the endoscope, and a package base member for accommodating the endoscope cover therein, the cover section is accommodated in the package base member so as not to overlap itself while being in the state of packaging.

A cover-system endoscope comprises the main body of an endoscope and an endoscope cover assembly for covering the main body of the endoscope. The endoscope cover assembly includes a direction changing means such as a tube body, an erecting base having a hinge section or a balloon for erecting the erecting base in order to change the direction of a medical treatment instrument which is inserted through the medical treatment instrument channel.

A stabilizer system for a vehicle that includes a stabilizer bar and an actuator for changing stiffness of the stabilizer bar, an electric current to be supplied to an electric motor that is a drive source of the actuator is changed based on various parameters. The supply current is made smaller in a situation in which an operational direction of the actuator is toward a neutral position, than in another situation. Further, the supply current is made smaller with an increase in a distance of the operational position of the actuator from the neutral position. Moreover, the supply current is made larger with an increase in a steering speed. In detail, when the supply current is determined by multiplying a basic supply current by a control gain, the control gain is set to change depending upon the above-indicated parameter, whereby the supply current is changed based on the parameters.

In an endoscope system including an endoscope having an insertion section to be inserted into a cavity under inspection, a bending portion which is provided in said insertion section near a distal end thereof and is bendable in at least two different directions and an operation section to which a proximal end of the insertion section is connected and a disposable protection cover having an insertion section cover for covering said insertion section of the endoscope and having formed therein an insertion section inserting channel into which said insertion section of the endoscope is insertable and at least one conduit channel, said insertion section and bending portion of the endoscope are formed to have a non-circular lateral cross section, a direction in which said non-circular cross section has a larger size is aligned with a direction in which said bending portion is bent by a maximum bending angle or a direction in which said non-circular cross section has a smaller size is aligned with a direction in which said bending portion is bent by a minimum bending angle.

A tip ring 18 for forming a lock mechanism for locking a tip cover 51 is formed in a circumferential part with a lock projection 22 for forming a lock groove 26 which becomes a recess of the lock mechanism on the endoscope tip side between the lock projection and curved rubber 19. A lock piece which becomes a projection of the lock mechanism of the tip cover 51 is locked into the lock groove 26 made by disposing the tip ring 18 and the curved rubber 19. To enhance the attachment property of the lock piece 52 to the lock groove 26, the lock projection 22 is formed with a slant projection 27 which becomes a slope for guiding the lock piece 52 to the lock groove 26. The slant projection 27 is formed as a slope projecting to the tip side from the lock projection 22 and rising from the tip bottom face to the top face of the lock projection 22.

A cover-fit endoscope can be used while being covered with a cover so that it is watertight. An appliance channel is extended through the cover and an appliance insertion inlet of the channel is open. This opening of the appliance insertion inlet is provided with an integral appliance plug. It is therefore possible to prevent the contaminated appliance plug from being fitted to the sterilized cover by mistake, and also to prevent leakage of the body fluids. Thus, the cover-fit endoscope is kept from contamination. The cover and the appliance plug are both discarded after use. The need for washing and disinfecting the cover-fit endoscope is eliminated, and use of the sterilized appliance plug is always ensured to reduce a fear of infection.
