摘要:
An endoscope includes an insertion section inserted into the patient's body. A distal end member is provided at the distal end of the insertion section. An illuminating system for illuminating a desired portion is attached to the end member. An observation unit is detachably attached to the distal end member. This unit includes a cylindrical support ditachably fitted to the end member. In the support are disposed an objective lens system for imaging an optical image of the portion illuminated by the illuminating system, a solid-state image sensor for converting the image to an electric signal, and electronic components connected to the sensor.

In a method of cleaning an endoscope, the open ends of an air/liquid supply valve cylinder, a suction valve cylinder, and a gas supply valve cylinder which are arranged in a control section of the endoscope are closed by stops. An air supply channel, a liquid supply channel, a suction channel, and a gas supply channel of the endoscope open at one end to a connector mounted on the distal end of the light guide cable of the endoscope. The connector is submerged in the liquid held in a tank. A cap is mounted on the distal end of the insertion section so that a nozzle communicating with the channels and a suction opening communicating with the suction channel open to the interior of the cap. The cap is connected to a suction pump by a suction tube. The pump is operated, thus sucking the liquid from the nozzle and suction opening through the four channels and the three cylinders, thereby cleaning the interiors of these channels and cylinders.

In a method of cleaning an endoscope, the open end of a suction valve cylinder, arranged within a control section of the endoscope, is closed by a stop. A cap is mounted on the distal end of an insertion section so that liquid may flow between a nozzle and a suction opening which are arranged at the distal end of the insertion section. The nozzle communicates with an air supply channel and a liquid supply channel, and the suction opening communicates with a suction channel. A stop is mounted on the open end of an air/liquid supply valve cylinder arranged in the control section, and a syringe is connected to the stop. The piston of the syringe is pushed, thus supplying liquid in the cylinder of the syringe into the cylinder and discharging the liquid from the other ends of the three channels through the channels and the valve cylinders, thereby cleaning the interiors of these channels and valve cylinders with the liquid.

A medical treatment method comprises orally inserting a first endoscope having a first treatment tool provided thereto into a body cavity, inserting a first insertion member insertion support tool from at least one of abdominal and transdermal cavities into the body cavity, inserting a second endoscope having a second treatment tool provided thereto into the body cavity through the first insertion member insertion support tool, grasping a lesioned part by the second treatment tool inserted into the body cavity by the second endoscope, cutting the lesioned part by the first treatment tool inserted into the body cavity by the first endoscope, and collecting the lesioned part.

A capsule-type medical device which is advanced through a digestive tract of a human being or animal for conducting an examination, therapy, or treatment is provided. The capsule-type medical device includes: a plurality of capsule bodies; a soft linking unit which links the plurality of capsule bodies and has an outer diameter less than that of any of the capsule bodies; and a joining member which joins two or more of the plurality of capsule bodies in a prescribed position.

In an endoscope of the present invention, while a cover indicator on a distal cover is aligned with a scope indicator on a main distal part, the distal cover is put on the main distal part in an axial direction at a certain insertion angle. Thereafter, the distal cover is rotated while being thrust in the axial direction. The stoppage of a locking convex part of a hook of the main distal part by a claw of a reinforcement member is released, and the locking convex part of the hook is positioned in a locking ditch of the reinforcement member. The head of the hook is constrained to move in the axial direction by means of a main distal cover that is an elastic member and the claw. The locking convex part is then fitted into the locking ditch reliably. Consequently, the distal cover can be fixed to the main distal part readily, freely detachably, and reliably with high positioning precision.

A non-ferrous metal mechanical part having a wear-resistant and smooth surface, and comprising a substrate of a metal selected from the group consisting of aluminum, aluminum alloy, nickel, and nickel alloy, and a surface layer formed on a surface of said substrate and containing chromium oxide (Cr.sub.2 O.sub.3) as a major constituent. The chromium oxide (Cr.sub.2 O.sub.3) is a substance which has been converted by heating a chromium compound, and an intermediate layer containing a reaction product between the substrate and chromium oxide in the surface layer is formed at an interface between the surface layer and the substrate.

Machine parts to be brought into contact with an elongated fibrous member each consists of a substrate of an iron series metal and a surface layer which has high wear-resistance and a good sliding property, and which contains chromium oxide as a major constituent. The chromium oxide is converted from a chromium compound upon heating. An intermediate layer containing a reaction product between the chromium oxide in the surface layer and the substrate is formed at an interface between the surface layer and the substrate.
摘要:
An electronic image pickup device for endoscopes is arranged so that at least two filters having mutually different transmitting wavelength ranges are inserted either alternatively or as a rotatable filter disc into an optical path of either an illuminating system or an image pickup system in order to make it possible to obtain either alternatingly or simultaneously color images produced by at least two kinds of rays having mutually different wavelength ranges. As an alternative the filter disc may be tilted relative to the optical axis.
