摘要： 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.

摘要： A surgical system includes: an overtube including a channel into which an endoscope is inserted; and an expansion device configured to ensure a surgical space by expanding an interior of a body at a distal side relative to a tip of the overtube. The expansion device includes a sheath and a wire configured to be protrudable from the sheath. The wire is configured to be switchable between a first configuration in which the wire protrudes from the sheath and a second configuration in which the wire protrudes from the sheath in a state where the wire is tilted, around a longitudinal axis, at an angle different from the first configuration.

摘要： A wide-angle optical system includes in order from an object side, a first lens unit having a negative refractive power, a second lens unit having a positive refractive power, and a third unit having a positive refractive power. At the time of carrying out a focal-position adjustment from a far point to a near point, the second lens unit is moved from a first position toward a second position. The third lens unit includes not less than three lens components, and not less than three lens components include a first lens component and a second lens component. The first lens component is a single lens and the second lens component is a cemented lens. Following conditional expression (1) is satisfied:

摘要： The present invention relates a puncture needle includes: a sheath having a longitudinal axis; a needle tube that is arranged inside the sheath to be moved along the longitudinal axis and that has a needle tip; and a protective tube that is arranged inside the needle tube to be moved along the longitudinal axis and that has a lumen into which a guide wire is inserted. The needle tube has a step portion formed at a position midway along the needle tube. The protective tube has a protrusion, which protrudes radially outward, on an outer peripheral surface thereof at a position midway nearer a proximal end side of the protective tube than the step portion is. A distal end of the protective tube is positioned at a position to protrude from the distal end of the needle tube when the protrusion abuts the step portion.

摘要： A wireless communication system includes two wireless communication devices. A first wireless communication device includes a first communicator and a second communicator. A second wireless communication device includes a third communicator and a fourth communicator. One of the two wireless communication devices includes a memory configured to store setting-related information. The second communicator or the fourth communicator is configured to transmit first setting-related information. Each time the first setting-related information is transmitted, a first processor is configured to generate the setting-related information different from the first setting-related information and the fourth communicator or the second communicator is configured to hold the setting-related information generated by the first processor as the first setting-related information.
