Abstract

An endoscopic system is a system which an insertion portion of an endoscope is inserted from an insertion opening of an object to observe an inner surface of the object. The endoscopic system includes an electromagnetic radiation unit configured to radiate electromagnetic waves, a detection section configured to detect the electromagnetic waves, and a determination section configured to determine whether the insertion portion is present in the object based on a detection result of the detection section. One of the electromagnetic radiation unit and the detection section is arranged outside the object, and the other is arranged at the insertion portion.

Claims

1. An endoscopic system which an insertion portion of an endoscope is inserted from an insertion opening of an object to observe an inner surface of the object, comprising:

an electromagnetic radiation unit configured to radiate electromagnetic waves;

a detection section configured to detect the electromagnetic waves; and

a determination section configured to determine whether the insertion portion is present in the object based on a detection result of the detection section,

wherein one of the electromagnetic radiation unit and the detection section is arranged outside the object, and the other is arranged at the insertion portion.

2. The system according to claim 1, wherein

the endoscopic system is an endoscopic system which is used by inserting the insertion portion into a lumen of a living body,

the electromagnetic radiation unit is arranged outside the lumen, and

the detection section is arranged at the insertion portion.

3. The endoscopic system according to claim 2, wherein the electromagnetic radiation unit is one of an infrared radiation element configured to radiate infrared rays and an electromagnetic radiation element configured to radiate electric waves having a wavelength longer than that of the infrared rays.

4. The system according to claim 3, wherein

the endoscopic system is dividable into a scope section having the insertion portion and a main body section configured to process and display an observation image observed through the scope section,

the determination section is configured in the main body section,

the detection section is incorporated in the insertion portion of the scope section, and

the electromagnetic radiation unit is not provided for the scope section.

5. The system according to claim 4, wherein

the main body section is mounted at a trolley, and

the electromagnetic radiation unit is previously incorporated in at least one of the main body section and the trolley.

6. The system according to claim 4, wherein the electromagnetic radiation unit is configured to be attachable to and detachable from an arbitrary position.

7. The system according to claim 3, wherein

the endoscopic system is dividable into a scope section having the insertion portion and a main body section configured to process and display an observation image observed through the scope section,

the determination section is configured in the main body section,

the electromagnetic radiation unit is arranged at a region excluding the insertion portion of the scope section, and

the detection section is arranged at the insertion portion of the scope section.

8. The system according to claim 7, wherein the electromagnetic radiation unit is mounted at an operating portion of the scope section.

9. The system according to claim 7, wherein

at least a distal end portion of the insertion portion of the scope section is formed as a hard portion, and

the detection section is arranged at the hard portion of the insertion portion.

10. The system according to claim 2, comprising a plurality of the electromagnetic radiation units.

11. The system according to claim 2, further comprising a second detection section configured to detect the electromagnetic waves,

wherein the determination section is configured to determine whether the insertion portion is present in the object based on a difference between a detection result of the detection section and a detection result of the second detection section.

12. The system according to claim 2, wherein the electromagnetic radiation unit configured to radiate electromagnetic waves modulated in a predetermined pattern as the electromagnetic waves.
