Abstract

A endoscope system having an insertion section to be inserted into a body cavity, an introducer for performing treatment in the body cavity, and a capsule endoscope. The capsule endoscope has an observation optical system and is used in combination with the introducer.

Claims

1. An endoscope system comprising:

a treating device which is configured to perform a treatment in a body cavity and which has an insertion section to be inserted into the body cavity through an opening to the body cavity, said insertion section having a distal end portion and a proximal end portion; and

an observation device which has at least an outer case and an observation optical system and which is used in combination with the treating device.

2. The endoscope system according to claim 1, wherein the treating device has no integrally incorporated observation functions.

3. The endoscope system according to claim 2, wherein a distal end of the insertion section has only an opening of a tube which guides the treating device into the insertion section.

4. The endoscope system according to claim 1, wherein the treating device has a support section which supports the observation device at the distal end of the insertion section, removably from the distal end thereof.

5. The endoscope system according to claim 1, further comprising a support mechanism which supports a device capable of moving the observation device when controlled by a device provided outside the body cavity.

6. The endoscope system according to claim 1, wherein the observation device has a function of switching a close view field to a distant view and vice versa.

7. The endoscope system according to claim 1, wherein the observation device includes a plurality of observation units which have differ in optical performance.

8. The endoscope system according to claim 1, wherein the observation device has a plurality of observation units, and a monitor system is provided, which can display images supplied from the observation units at the same time or at least one selected one of the images.

9. The endoscope system according to claim 1, wherein the outer case of the observation device has a holding section which secures the observation device to a body wall.

10. A method, wherein an observation device and an observation-device retaining device are simultaneously or independently inserted through an opening into a body cavity, the observation device is held at a desired position by using the observation-device retaining device, and a treating device is inserted through the opening into the body cavity to perform treatment.

11. The method according to claim 11, wherein the observation-device retaining device is common to an endoscope or the treating device.

12. The method according to claim 11, wherein the treating device is inserted into the body cavity, by using, as an insertion guide, a guide wire or an overtube inserted into the body cavity into the body cavity through the observation-device retaining device or the endoscope.
