  • Patent number: 9125557
    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. By magnetically controlling the magnetic driven parts, the capsule endoscope is allowed to rotate or move under the control of the control device to achieve better image retrieval results and improve over the poor image retrieval results obtained by the prior art since the location and direction of a traditional capsule endoscope, relying solely on the contractions of the digestive tract, cannot be controlled.

  • Publication number: 20150087898
    Abstract: A capsule endoscope magnetic control system includes a control handle assembly, and a capsule endoscope having a controlled unit, a wireless power receiving unit, an image capturing unit, a processing unit, and a wireless communication unit. The control handle assembly includes a magnetic control unit for generating a magnetic field and a wireless power transmission unit for generating electromagnetic waves. After the capsule endoscope is placed inside a test object, the controlled unit fixed to the outside of the capsule endoscope changes the rotational direction of the capsule endoscope according to the changes in the magnetic field. The wireless power receiving unit generates an induced current. The image capturing unit generates an image data, which is received and converted by the processing unit into an image signal, which is transmitted by the wireless communication unit to the control handle assembly. Therefore, the capsule endoscope has a long battery life.

  • Publication number: 20130345506
    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.
