Abstract
An object of the present invention is to provide an emission marker for being indwelled in a lumen, the emission marker having: a base part; a coil wound around the base part; an emission part electrically connected to the coil; and a cover part for covering at least the base part and the coil, wherein the emission part has a light source that emits visible light. Additionally, the present invention relates to a detector for detecting, from outside of a lumen, an emission marker indwelled in the lumen, the detector having a detection unit having an antenna that acts with a coil of the emission marker.
Claims9
A detection system comprising an emission marker and a detector, wherein the emission marker is indwelled in an inner surface of a lumen of a digestive tract which is selected from an esophagus, a stomach, a duodenum, a small intestine, a large intestine, a colon, or a rectum;
- the emission marker comprising:
- a base part;
- a coil wound around the base part, wherein the coil receives an induced current from the detector outside the lumen of the digestive tract that is separate from the emission marker;
- an emission part electrically connected to the coil;
- and
- a cover part for covering at least the base part and the coil,
- wherein the emission part has a light source that emits visible light, and
- wherein the emission marker has a size enabling insertion into a forceps channel of an endoscope, and
- wherein the detector comprises a detection unit having an antenna that acts with the coil of the emission marker.
