摘要:
At the tip of an insertion part of an endoscope, an object window for regular observation use is positioned at almost the center, directly connected to which, said object window for fluorescent observation use is provided, and at the both sides of the object window for regular observation use and the object window for fluorescent observation use, two illumination windows are provided. A forceps hole which is an opening part at the tip side of a forceps channel which is inserted into the insertion part is provided at the lower right of the object window for regular observation use, and a treatment tool which is inserted through a forceps insertion channel is to be extruded from this forceps hole. By this way, on monitor images at both of white light observation and fluorescent observation, the treatment tool such as a forceps or the like is designated at almost the same position to improve the manipulation capability.

An imaging system for use with an endoscope, including a light source which emits white light and excitation light which will produce a fluorescence response by an object under inspection, an imaging camera including separate paths for processing images produced by white light and excitation light, a selection device that causes the imaging device to operate in a white light mode or an excitation light mode, and a protective device that prevents damage to high-sensitivity imaging components from exposure to excessive light input. Fluorescent image data are separated into at least red and green color bands which are separately processed to produced a video display in which normal tissue is displayed in predetermined specific color, and abnormal tissue in one or more distinctly different colors. In one embodiment, an image color interpretation guide is provided in the form of multiple color bars which are superimposed on a single video display device with the image display. of different kinds. In another embodiment, color control is provided by adjusting the amplification of the imaging components for each of the color bands while viewing tissue known to be normal using a recursive algorithm until the ratio of the maximum values of the color separation signals fall within a predetermined range. The high-sensitivity imaging components are protected by controlling impingement of light on the imagining components, selectively controlling emission of white and excitation light from the light source, and controlling the power source for the imaging components.

A fluorescent imaging device to prevent the breakdown of a fluorescent image high-sensitivity imaging apparatus has a light source for endoscope use which selectively switches between an excitation light and a white light. This introduces a light into a light guide of an endoscope and such light is emitted onto an object. A fluorescent image high-sensitivity imaging device images the fluorescences obtained by excitation with the excitation light which is emitted onto the object. A white light imaging device images a white light image obtained from the white light which is emitted onto the object. A switch inputs a power source onto the fluorescent image high-sensitivity imaging apparatus and there is a mechanism to prevent overprint on an image plane of the fluorescent image high-sensitivity imaging apparatus which is in the imaging condition with the power source inputted. A fluorescent observation image generating device generates a fluorescent observation image signal for fluorescent observation use, and outputted from the fluorescent image high-sensitivity imaging measure of the imaging part is in electric signal from; which a white light observation image signal used for white light observation is derived.

摘要:
A socket section 72 for providing a first light guide 13 is supported movably in an endoscope main body 4, and a plug section 62 for fixing a second light guide 15 is disposed in an endoscope insertion section 5. The socket section 72 is configured to move freely in an insertion direction of the endoscope insertion section 5 and to a direction orthogonal with respect to the insertion direction. Furthermore, an attachment-detachment-detecting switch 33 is disposed in the endoscope main body 4 so as to detect that the endoscope insertion section 5 has been separated from the endoscope main body 4 before the plug section 62 is freely detached from the socket section 72. By this configuration, it is possible to attach the endoscope insertion section from the endoscope main body and detach them easily and reliably, in particular, to reduce loss of light caused by the attachment and the detachment.
