Abstract:
A supporting apparatus for supporting insertion of a flexible insertion member into a subject and removal of the insertion member includes an attention point acquisition unit, a first displacement acquisition unit and a determination unit. The attention point acquisition unit specifies at least one first attention point specified by a shape of the insertion member. The first displacement acquisition unit acquires a first displacement of the first attention point. The determination unit determines how a state of the insertion member or the subject is at a position corresponding to the first attention point, based on displacement information including information on the first displacement.

Abstract:
Example embodiments of the present invention relate to a manipulation support apparatus. The apparatus may include a processor and memory storing instructions that when executed on the processor cause the processor to perform the operation of acquiring detection data from a sensor provided in an inserted object which is inserted into a subject body. The detection data may be associated with a state of the inserted object. The apparatus then may decide setting information based on at least one of inserted object information and the user information. The apparatus then may generate support information for a manipulation of the inserted object based on the detection data and the setting information.
Abstract:
A light guide sensor includes a light source, a light guide member comprising a core which guides light radiated from the light source, a cladding formed around the core, and at least one detecting portion is formed, and a light receiving unit which receives the light that has been guided by the member and has passed via the detecting portion. The detecting portion includes a first opening formed by removal in the outer circumference of the member so that at least part of the cladding is left by a thickness such as not to transmit the light from the core, and a second opening formed within the range of the first opening to transmit the light from the core. A method of forming such a light guide sensor is provided.
