Abstract: Provided is a forceps device including: an elongated body portion; a pair of gripping pieces that are provided at a distal end of the body portion, at least one of which possesses conductivity; a motive-power output portion that is provided at a base end of the body portion; a motive-power converting mechanism that connects the pair of gripping pieces and the motive-power output portion, and that converts motive power output by the motive-power output portion into relative opening/closing motions of the pair of gripping pieces; and an insulating member that is provided in a pathway connecting the pair of gripping pieces and the motive-power output portion via the motive-power converting mechanism.

Abstract: Provided is a manipulator system including: a manipulator provided with an insertion section, a movable section disposed at a distal end of the insertion section, and a drive unit that is disposed at a proximal end of the insertion section and that drives the movable section; an operation input unit with which an operation input to the manipulator is input; a control unit for controlling the drive unit based on the operation input; an endoscope; an overtube having a first channel and a second channel; and a unit for calculating a shifted angle of the endoscope relative to the first channel about a longitudinal axis, wherein, on the basis of the shifted angle, the movable section is rotated relative to the second channel to match the up/down direction of a coordinate system fixed to the endoscope and the up/down direction of a coordinate system fixed to the movable section.

Abstract: A surgical system is provided with: a first medical instrument that is disposed inside a body cavity and that has an observation unit and a marking unit that is capable of being positioned with respect to the body cavity; a second medical instrument that is disposed outside the body cavity and that has a treatment section and a driving unit for driving the treatment section; a distance measuring unit that measures the distance between the marking unit and the treatment section; and a control unit that controls the driving unit on the basis of the distance measured by the distance measuring unit.

Abstract: With an object of suppressing unintended motion of a slave device due to an erroneous operation of a master device, an operation input device includes: a one-dimensional operation unit which can generate a one-dimensional motion command signal; and a two-dimensional operation unit which can generate a two-dimensional motion command signal, wherein the one-dimensional operation unit and the two-dimensional operation unit can be operated independently from each other.
