摘要： Provided are an optical unit and an endoscope that can enhance the airtightness between a holding tube and a cover glass without a joining member flowing into a distal end surface of an optical lens while maintaining the attachment accuracy of the cover glass and can secure a fine diameter and a wide angle visual field. A spacer 144 is disposed between a cover glass position restricting part 136 of a holding tube 132 of an optical unit 10 and a cover glass 108. The position of the cover glass 108 in an optical axis is restricted by the cover glass position restricting part 136 via a spacer 144. An external diameter D1 of a first end surface 144A of the spacer 144 is smaller than an internal diameter D2 of a cover glass fixing part 134 of the holding tube 132. A solder pool part is provided in a region 156, which is surrounded by a side surface 144C of the spacer 144, the cover glass fixing part 134, and the cover glass position restricting part 136.

摘要： An endoscopic treatment instrument includes a guide pipe and a guide sheath. The guide pipe through which the insertion portion is inserted so that a distal side of a distal end of the insertion portion and a distal side of a first distal end are observable through the first distal end by the observation optical system of an endoscope or so that the distal side of the distal end of the insertion portion is observable by the observation optical system while the distal end of the insertion portion is protruded relative to the first distal end. The guide sheath has an inside diameter to insert the insertion portion therethrough so that the distal end of the insertion portion is configured to protrude relative to the second distal end and is inserted through the guide pipe so that the second distal end is configured to protrude relative to the first distal end of the guide pipe.

摘要： Methods and apparatuses for space-optimized visualization catheters are provided. Some embodiments utilize complimentary metal-oxide-semi-conductor (“CMOS”) technology integrated into a CMOS camera train holder system that may be a stand-alone component for use with a visualization catheter, such as a baby endoscope, or may be fabricated/extruded as a part of the catheter itself. Some embodiments of apparatuses, methods, and equivalents thereto provide better direct visual feedback to the medical personnel performing the procedure while providing a similarly-sized outer diameter visualization catheter device having an increased space therein for additional lumens and equipment or by reducing the overall outer diameter of the visualization catheter.
