Abstract: An appropriate stereoscopic image of a subject is readily acquired. Provided is a stereoscopic endoscope device including two image capture elements spaced apart from each other and disposed at a distal end of an insertion section to be inserted into a subject; an angle changing mechanism that changes a relative angle between optical axes of the image capture elements; a distance sensor that detects the distance from the image capture elements to the subject; and a controller that controls the angle changing mechanism on the basis of the distance detected by the distance sensor.

Abstract: 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.

Abstract: A medical overtube device has a main body formed by articulating a plurality of nested units into a first group of nested units and a second group of nested units and is bendable in a longitudinal direction thereof; a first shape-fixation mechanism configured to fix a shape of the first group which has a first wire, both end of the first wire coupled to the first group of nested units and a first pulley configured to be wound by the first wire; and a second shape-fixation mechanism configured to fix a shape of the second group which has a second wire, both end of the second wire coupled to the second group of nested units; and a second pulley configured to be wound by the second wire, wherein the first shape-fixation mechanism is configured to release the fixed shape of the first group independently from the second shape-fixation mechanism.

Abstract: A mantle tube including a bendable member, which is formed in such a way as to be received in an elongate, annular, cylindrical member, includes two fixed sites that are fixed to the cylindrical member and a bendable site that is interposed between these fixed sites and bendable in a direction intersecting a longitudinal direction thereof, an angle adjustment member that is capable of adjusting a bending angle of the bendable site, and an angle holding mechanism that is capable of holding, at any desired bending angle, the bendable site bent by the angle adjustment member.
