An endoscope according to the present invention includes: an elongated insertion portion inserted in an examination object; an LED which is provided in a distal end portion of the insertion portion and is driven by supply of electric power; an image pickup portion which is provided in the distal end portion on a rear end side in the insertion direction than the LED, and which picks up an image of the examination object; a power supply line for power supply, a distal end in an insertion direction of which is positioned in the distal end portion on a rear end side in the insertion direction than the image pickup portion, and which is inserted in the insertion portion.

Endoscope with thin plate-like substrate

An electronic endoscope having an illuminating section in which an LED for illumination that emits illuminating light to illuminate an observed site is provided and a C-MOS image sensor which has an image pickup surface on which an optical image is formed and outputs a video signal.

Electronic endoscope

An endoscopic optical adapter freely attachable to and detachable from an endoscope according to the present invention includes an adapter-side observational optical system facing an endoscope-side observational optical system provided with a solid-state image device placed in a tip constituent member of the endoscope, a unit body in which the adapter-side observational optical system is fixedly placed, an adapter body on which a first concave portion with the unit body placed therein while being free to rotate and a second concave portion with at least a part of the tip constituent member placed therein are formed, and a positioning portion which is provided in each of the adapter body and the tip constituent member and which adjusts the positional relationship between the tip constituent member and the adapter body to be a predetermined positional relationship.

Endoscopic optical adapter freely attachable to and detachable from endoscope

An endoscope system includes a movement detector for detecting an operator's movement, a signal processor for processing a signal the detector detects, and a control for controlling drive which drives a medical device according to an output signal of the signal processor. The endoscope system bends a bending section of an endoscope serving as a medical device according to the operator's movement, and thus orients the observation field of view to a direction the operator intends or controls the movement of a treatment adapter serving as a medical device. The endoscope system includes a superimposing means for superimposing an image associated with the operator's movement onto an image acquired by an imaging device associated with the endoscope system.

Endoscope system with automatic control according to movement of an

A medical system has a detecting device for detecting three dimensional image information about a living body, a signal processing circuit for processing the image signal transmitted from the detecting device, and an object information reproduction device. The object information reproduction device comprises a movable displacement element which is touched by the operator and acts according to the output from the signal processing circuit so as to cause the operator to tactually sense information about the object. Thus, the operator is able to recognize the degree of unevenness in a tactile manner by touching the displacement element. Other embodiments include means for sensing and reproducing hardness and temperature of the object.

Medical system having object information reproduction means for palpation

The distal end of an endoscope is provided with at least an objective optical system and a torque transmission member for supporting a rotating treatment member. The distal end of the torque transmission member comprises a hollow to which a support axis formed in the rotating treatment member is fitted, a slit for guiding a protrusion formed on the external circumference of the support axis, and a locking member for locking the protrusion in the slit. Torque is transmitted from the torque transmission member to the rotating treatment member by means of the protrusion formed on the external circumference of the support axis of the rotating treatment member and the slit formed on the torque transmission member for guiding the protrusion.

A diaphragm blade is rotatably secured by a rotational shaft disposed in a base. The aperture blade has a diaphragm aperture at the central portion thereof. A shape-memory alloy which deforms in accordance with temperatures and an elastic member are respectively secured to the end portions of the aperture blade. The other end portion of each of the shape-memory alloy and the elastic member is secured to the base. The shape of the shape-memory alloy is deformed by changing the temperature so that the aperture blade is displaced. In consequence, a diaphragm aperture formed in the aperture blade is positioned/retracted from the optical path so as to change the quantity of light which is transmitted through the optical path.

An eddy current flaw detecting endoscope apparatus has an endoscope having an elongate insertable part and an objective optical system provided on the tip side of the insertable part. A flaw detecting device is provided on the tip side of the endoscope. A signal processing device processes a signal for the flaw detecting device. An eddy current flaw detecting apparatus detects a flaw in an object to be inspected and generates a flaw detecting signal. A controlling device generates a control signal controlling a controlled device with a flaw detecting signal of the eddy current flaw detecting apparatus.
