A position detection system includes: an object to be detected having a magnetic field generator to generate a position detecting magnetic field, and configured to be introduced into a subject; detection coils, each being configured to detect the position detecting magnetic field to output a detection signal; and a processor including hardware. The processor is configured to: correct measured values of detection signals output from the detection coils using a magnetic field generated by applying the position detecting magnetic field to a metal plate, the metal plate being disposed on a side opposite to an area to be detected of the object to be detected relative to the detection coils; and calculate at least one of a position and a direction of the object to be detected using the corrected measured values of the detection signals.

A system and method for capturing in-vivo images of an endoluminal network and generating a pathway for directing an endoluminal robot to drive a catheter to a desired location.

The introducing apparatus comprises the operating section, which is easy to grip and easy to operate, mounted therein by providing the dial of the operation element to perform a bending operation of the bending section and a part of the rotary mechanism alone while avoiding an operation range of the operating section for fingers of a gripping hand.

A towing device for endoscopy including a connecting portion connected to a wire of an endoscope to be moved, wherein a body of the connecting portion is broken when a set amount of tension or more is applied to the connecting portion; a guide portion including an inner path through which the connecting portion moves; a clip portion positioned at an opposite direction of the wire with respect to the guide portion and hooked by the connecting portion to be closed and grip body tissues; and an extension portion configured to move together with the guide portion and having a magnetic force.

An interactive magnetically controlled capsule endoscopy system comprises a pose monitoring module, an automatic cruise control module, a capsule and a human-computer interaction module. The pose monitoring module is configured to continuously detect pose of a subject in real time, and the automatic cruise control module includes a magnetron device and a control terminal, wherein the magnetron device is configured to generate a driving magnetic field to drive the capsule to move in the digestive tract of the subject and the control terminal runs an automatic cruise examination program. The automatic cruise examination program is configured to initiate a pose change whenever needed by the automatic cruise examination program, perform real-time alignment of the magnetron device, so that the subject is within the effective working range of the driving magnetic field and drive the capsule to move in and acquire image data of the digestive tract of the subject according to data of the pose of the subject.

The present invention discloses an ingestible endoscopy capsule including a permanent magnetic dipole, and an external positioning and orientation system to position and/or orientate the capsule in a target area including at least one magnet for positioning and/or orientating the endoscopy capsule within a patient, and one diagnostic imaging means.

An endoscope includes a distal end portion in which an optical unit and a treatment instrument channel are held such that a photographing optical axis, a central axis of the distal end portion, and a central axis of the treatment instrument channel are linearly aligned When viewed from an end face of the distal end portion. The first magnet and the second magnet are arranged at non-rotationally-symmetric positions with respect to the photographing optical axis, and a region of the optical unit, which is on a side where a distance between the first magnet and the second magnet on an arc of a circle around the photographing optical axis is short, faces the treatment instrument channel.

The present invention discloses a system to control a movement of a magnetic capsule using an external magnet control system. The external magnet control system includes more than one external magnetic balls, and at least one external magnetic ball can be moved freely in five degrees of the freedom.

A computer-implemented method of internally printing a biostructure on a damaged area of a patient. The method includes: assembling a first bioprinter capsule and a first cartridge capsule to form an assembled bioprinter internally within the patient based, at least in part, on directing one or more magnetic fields towards a first bioprinter capsule and a first cartridge capsule, moving the assembled bioprinter to the internally damaged area of the patient based, at least in part, on altering the one or more external magnetic fields directed towards the assembled bioprinter, and printing, via the assembled bioprinter, a first biostructure onto the internally damaged area of the patient based, at least in part, on altering the one or more external magnetic fields directed towards the assembled bioprinter, wherein the one or more external magnetic fields are sequentially altered to incrementally move the assembled bioprinter along at least one plane.

A system and method for constructing fluoroscopic-based three-dimensional volumetric data of a target area within a patient from two-dimensional fluoroscopic images acquired via a fluoroscopic imaging device.
