Provided are a forceps including: a shaft; a wire that is movable in a longitudinal direction inside the shaft; and a first arm and a second arm, each of which has a first jaw or a second jaw, that are connected to each other in a pivotable manner by means of a third joint. The first arm is connected to a distal end of the shaft in a pivotable manner by means of a first joint, and the second arm is connected to a distal end of the wire in a pivotable manner by means of a second joint. The third joint is provided between the first jaw and the first joint and between the second jaw and the second joint, and is disposed lateral to the wire in a state in which the first and second jaws are open. The first and second jaws are closed while the third joint is moving outward in the lateral direction with respect to the shaft.

Forceps and tissue collection method

An endoscope light source device includes a light source device and a light source controller. A first light and a second light are narrow band light in a blue region. A third light is in a green region. A fourth light is in a red region. A first light amount ratio is a ratio of a sum of the light amounts of the first light and the second light, the light amount of the third light, and the light amount of the fourth light. A second light amount ratio is a light amount ratio of the first light and the second light. The light source controller adjusts the light amount ratio of the first light and the second light to achieve the second light amount ratio so as to adjust the color representation from a yellow region to a red region in an image of an object.

The resolution of narrow band imaging is improved, while color reproducibility is improved when performing white-light observation. Provided is an endoscope system including an image pickup device having three types of color filters, said types being blue, green, and magenta, and also including an image processor that generates an image by processing a signal acquired by the image pickup device. The image processor includes a ratio calculator that calculates the ratio between a blue signal and a magenta signal, and also includes a red-signal generator that generates a red signal based on the ratio calculated by the ratio calculator.

The invention relates to an reimaging optical system that has a sufficiently enhanced magnification and better performance, and an endoscope using the same. The reimaging optical systemis adapted to re-form an image by an image guideon a solid-state imaging devicehaving a diagonal length of 6.5 mm or longer, and satisfies the following condition.0.6&#x3c;(&#xd7;|&#x3b2;|)/&#x2003;&#x2003;(1).Here D is the diameter of the image guide, &#x3b2; is the optical transverse magnification of the reimaging optical system, and V in mm is the minor axis direction length of an imaging area of the solid-state imaging device

Reimaging optical system and endoscope using the same

An endoscope includes an image acquisition device, an objective optical system having a predetermined optical axis, first and second light guiding members that emit first and second illumination light, first and second optical systems that refract the first and second illumination light to intersect with the optical axis of the objective optical system, and a tube-like inserted portion having a distal end. The first and second optical systems are disposed at substantially mirror symmetrical positions at the distal end having a shoulder portion that becomes narrower toward the tip. When viewed from the optical axis direction of the objective optical system, the inclination directions at substantially the center of the outer surfaces of the first and second optical systems and straight lines that pass through the center of the objective optical system and the centers of the first and second optical systems form angles of 30&#xb0; or less.
