20090253966 | DISTAL END PORTION OF ENDOSCOPE - An air-supplying/water-supplying nozzle for delivering fluid to a second imaging unit for observing a body to be examined which is provided at a distal end portion of an insertion portion to be inserted into a body to be examined in a projecting manner is provided on a non-projecting face of the insertion portion, the non-projecting portion being disposed at a position lower than a flat face of a middle step portion on which the second imaging unit is disposed. Thereby, such a possibility can be reduced that an opening portion of the air-supplying/water-supplying nozzle is caught by an object to be examined and observation or diagnosis work conducted using an observation optical system of an object-contacting type can be conducted. | 10-08-2009 |
20090326327 | ADAPTER FOR OBJECTIVE LENS - High-precision observation is made possible while allowing contact between a distal end of an objective lens and an optical element without damaging the distal end of the objective lens and the optical element even when attaching to and detaching from the distal end of the objective lens. Provided is an objective lens adapter including a fixed member that is fixed to a lens tube of an objective lens, a distal-end member including an optical element that is made to be placed in contact with the distal-end surface of the objective lens, and an elastic member that is disposed between the distal-end member and the fixed member and that urges the optical element in a direction that causes the optical element to contact the distal-end surface of the objective lens. | 12-31-2009 |
20090326328 | Protective Cap for Arthroscopic Instruments - A protective cap for use on arthroscopic instruments and sheaths disposed over arthroscopic instruments. The cap protects the distal end of the instrument from accidental damage caused by other instruments used during a surgical procedure. The portion of the cap that covers a view port on an arthroscope is transparent in order to allow a user to see through the instrument and through the cap. | 12-31-2009 |
20100069720 | SPECTROSCOPICALLY ENHANCED IMAGING - The present invention provides systems and methods for the spectroscopic determination of the physical characteristics of the tissue under observation by an autofluorescence or other endoscope without the requirement of contacting the tissue directly. The optical probe contained in the endoscope itself is passive and may be either built into the endoscope or positioned in a biopsy channel of same. The spectroscopic information, combined with other information provided by the endoscope such as total fluorescence, improves the sensitivity and specificity of the identification of precancerous or cancerous lesions. | 03-18-2010 |
20100152540 | Endoscope, Optical Member, and Method of Manufacturing Endoscope - An endoscope includes a distal end portion body | 06-17-2010 |
20110034774 | Light-Diffusing Safety Cap - A light-diffusing safety cap for use with a light cable that couples an endoscope to a high intensity light source. The light-diffusing safety cap can be detachably or releasably coupled, in lieu of the endoscope, to the light cable, such that when the high intensity light source emits a high intensity light and the endoscope is not connected to the light cable, the light-diffusing safety cap reduces the intensity of the high intensity light emitted to the environment and provides an indication that the high intensity light source is activated when the endoscope is not connected to the light cable. | 02-10-2011 |
20110313253 | ENDOSCOPE APPARATUS - An endoscope apparatus includes a transparent member provided at a distal end of an insertion portion of an endoscope, opposed to an image pickup optical system, a transducer attached to an inner surface of the transparent member, a diffraction grating provided on an outer surface of the transparent member, for converting ultrasound vibration from the transducer to a surface acoustic wave Φ that propagates on the outer surface of the transparent member and a conversion section provided in an outer peripheral corner of the transparent member for converting the surface acoustic wave Φ to a bulk wave Φb that scatters into the transparent member. | 12-22-2011 |
