Abstract

An insertion device comprises a long-sized insertion portion to be inserted into a subject; a propulsion force generating portion provided on the outer peripheral face of the insertion portion; a rotating portion for rotating the propulsion force generating portion on the longitudinal axis of the insertion portion; an observation portion for observing an image of the subject; and a display control portion for displaying, on a screen of a display device, the image of the subject based on an observation signal outputted from the observation portion in a manner corresponding to a rotation of the propulsion force generating portion.

Claims

1. An insertion device comprises:

a long-sized insertion portion to be inserted into a subject;

a propulsion force generating portion provided on the outer peripheral face of the insertion portion;

a rotating portion for rotating the propulsion force generating portion on the longitudinal axis of the insertion portion;

an observation portion for observing an image of the subject; and

a display control portion for displaying, on a screen of a display device, the image of the subject based on an observation signal outputted from the observation portion in a manner corresponding to a rotation of the propulsion force generating portion.

2. The insertion device according to claim 1, wherein the observation portion is disposed at a tip of the insertion portion.

3. The insertion device according to claim 1, wherein the observation portion is integrally provided to the insertion portion to move along with the rotation of the propulsion force generating portion.

4. The insertion device according to claim 1, further comprising a propulsion force generating portion detection portion for detecting a rotation state of the propulsion force generating portion, wherein the display control portion displays, out of observation signals outputted from the observation portion, an image of the subject based on an observation signal corresponding to a detection signal of the propulsion force generating portion detection portion.

5. The insertion device according to claim 1, further comprising a rotating portion detection portion for detecting a rotation drive state of the rotating portion, wherein the display control portion displays, out of observation signals outputted from the observation portion, an image of the subject based on an observation signal corresponding to a detection signal of the rotating portion detection portion.

6. The insertion device according to claim 1, wherein the propulsion force generating portion is configured of a spiral-shaped portion.

7. The insertion device according to claim 3, wherein the observation portion is detachable from the tip of the insertion portion.
