Abstract: A magnetic-controlled system for colonoscopy is provided, including a supporting rod, an image retrieving unit, annular sheaths and a controlling device. After the supporting rod enters the large intestine of an organism via the anus, the image retrieving unit at the top end segment of the supporting rod then retrieves images of the large intestine. The annular sheaths are disposed around the supporting rod. Each of the annular sheaths has a plurality of magnetic-driven parts. The controlling device has a rotatable magnetic driving part. The magnetic-controlled system allows the rotation of the magnetic-driven parts, which in turn rotates the annular sheaths to facilitate the supporting rod moving smoothly in the large intestine, by rotating the magnetic driving parts and forward moving of the controlling device. Therefore, the pain experienced by the patients when the supporting rod is moving ungainly inside the intestine is greatly relieved.

Abstract: A magnetic maneuvering system for capsule endoscope includes the capsule endoscope, an annular fitting sleeved around the outer surface of the capsule endoscope. A plurality of magnetic driven parts are provided and distributed on the annular fitting member. The control device includes a magnetic driving part for magnetically actuating the magnetic driven parts, thus enabling the capsule endoscope to rotate and move in an organism as a result of the actuation of the magnetic driven parts.
