Abstract: An apparatus for detecting a focused condition of an optical system, in which a light-receiving means arranged at a fixed position corresponding to a focus position photometrically detects a focused condition. A light beam having a definite shape is projected onto an object to be imaged by a light projection means. The reflected light beam is conducted along an optical axis of the optical system, deflected, and detected by the light receiving means for determining whether a focused condition exists. Several embodiments are disclosed for projecting a light spot of high contrast of the object and for detecting a focused condition on the basis of the intensity distribution of light received by the light-receiving means. The apparatus may be applied to an endoscope and other optical systems.

Abstract: An endoscope-use camera attached to the eyepiece section of an endoscope has conventionally been provided with an automatic exposure control device including a light sensing element and capable of automatically determining an exposure value in accordance with a quantity of light received. Disclosed herein is an automatic exposure control device which further comprises a control member disposed at the eyepiece section of an endoscope and having a shape depending on the thickness of an image transmitting optical system, and a device for determining in cooperation with the control member the correction value for an exposure value in accordance with the thickness of the image guide when the endoscope is attached to the camera.

Abstract: A device for diagnosing body cavity interiors which comprises an elongated insertion portion for introduction into a body cavity. The insertion portion includes a guide tube extending along the length thereof with a window formed in the insertion portion at the end of the guide tube. An ultrasonic wave probe is positioned at the forward end of the insertion portion, the ultrasonic head transmitting ultrasonic waves to body tissue and receiving ultrasonic waves reflected from the body tissue. A curved portion is formed in the insertion portion at a position adjacent to the ultrasonic head. A optical tube is inserted into the guide tube wherein the forward end of the optical tube is positioned in the window of the insertion portion, such that the body tissue may be observed through the optical tube. Further, an optical tube fitting member is coupled to the rear of the insertion portion with the optical tube being inserted into the insertion portion through the fitting member.

Abstract: A surgical cutting instrument essentially comprises an outer sheath tube, an inner stationary tube which is disposed within said outer sheath tube such that the distal end of the inner tube projects from the distal end of the outer sheath tube and is provided with a cutting opening for drawing cut tissue chips at the peripheral wall of the distal end of the inner tube and a sliding member which is slidably disposed between said outer sheath tube and said inner tube so as to open and close said cutting opening and is provided with an outer cutting edge which engages an inner cutting edge of said cutting opening, on the distal end edge of the sliding member, whereby a body tissue is cut by axially and slidingly reciprocating said sliding member to open and close said cutting opening and cut tissue chips are withdrawn from the body by suction through a suction channel of the inner tube.
