Abstract

Provided is an endoscope insertion shape analyzing system comprising an insertion state acquiring unit for acquiring the coordinate values of plural portions in the inserted portion of an endoscope in a subject, and an insertion shape detecting unit for detecting the insertion shape of at least one portion of the inserted portion in the subject, on the basis of the coordinate values of the plural portions. Further comprised are a coordinate plane setting unit for setting plural coordinate planes in accordance with the coordinate values of the plural portions and the insertion shape, and an insertion shape projecting unit for projecting the insertion shapes individually on the plural coordinate planes. Still further comprised is an insertion shape judging unit for judging whether or not a predetermined shape exists in the insertion shapes projected individually on the plural coordinate planes.

Description

technical field [0001] The present invention relates to an endoscope insertion shape analysis system and a living body observation system, and more particularly, to an endoscope insertion shape analysis system and a living body observation system capable of acquiring information for assisting an insertion operation of an insertion portion of an endoscope. Background technique [0002] Endoscopes have conventionally been widely used in the medical field, industrial field, and the like. In addition, the endoscope is used, for example, in the medical field for observation and various treatments of living tissue and the like. [0003] In particular, when the insertion part of the endoscope is inserted from the anus side of the subject to observe and perform various treatments on the lower digestive tract, in order to smoothly insert the insertion part into the curved body cavity, the An endoscope insertion shape analysis system capable of detecting the position of the insertion...
