Abstract

Capsule endoscopy represents an appealing alternative to conventional endoscopic procedures that cause discomfort to the patient and are considered tedious to the operator due to difficulty of endoscope manipulation because of the limited degrees of freedom (DOF). Therefore, active capsule endoscopy has become an important research topic as it enables targeted intestinal examination by controlling the capsule’s movements inside the gastrointestinal (GI) tract. An overview of the current state of art of active capsule endoscope systems is provided in this paper, discussing their different locomotion methods that can be classified to internally actuated and externally actuated. In addition to providing an overview of capsule endoscope functions, since the requirements of capsule endoscopy actuation (passive or active locomotion) might derive from the purpose/ function of the capsule. Developed capsule endoscope systems are discussed and systems with similar locomotion methods are compared. Generalized control schemes are presented to demonstrate the general control strategies implemented in each group of active capsule endoscope systems.

主动/机器人胶囊内窥镜-综述

胶囊内窥镜是一种有吸引力的替代传统的内窥镜手术，由于内窥镜操作的困难，由于有限的自由度（DOF），给患者带来了不适，并且对操作者来说被认为是乏味的。因此，主动胶囊内窥镜通过控制胶囊在胃肠道内的运动，实现对肠道的针对性检查，成为一个重要的研究课题。本文综述了主动胶囊内窥镜系统的研究现状，讨论了其不同的运动方式，可分为内驱动和外驱动。除了提供胶囊内窥镜功能的概述外，由于胶囊内窥镜驱动（被动或主动运动）的要求可能源于胶囊的目的/功能。讨论了现有的胶囊内窥镜系统，并对运动方式相似的系统进行了比较。提出了通用控制方案，以演示在每组主动胶囊内窥镜系统中实现的通用控制策略。
