Abstract

A treatment endoscope includes that a body cavity insertion portion which includes a main body distal hard portion, and a main body curving portion provided to a proximal side of the main body distal hard portion, one or more treatment arm/arms projecting to a distal side from the main body distal hard portion, each of the treatment arm/arms including a curving mechanism, an operation portion provided to the proximal side of the body cavity insertion portion, and an observation section configured to image a field of view in a body cavity, the observation section including an imaging section provided within the main body distal hard portion. The treatment endoscope includes that an operation portion attaching/detaching mechanism configured to removably attach the operation portion to the body cavity insertion portion, and an observation section attaching/detaching mechanism configured to removably attach the observation section to the body cavity insertion portion.

First claim

What is claimed is:

1. A treatment endoscope comprising:
a body cavity insertion portion which includes a main body distal hard portion, and a main body curving portion provided at a proximal side of the main body distal hard portion;
at least one treatment arm which includes a curving mechanism and projects to a distal side from the main body distal hard portion of the body cavity insertion portion;
an observation section configured to image a field of view in a body cavity, the observation section including an imaging section provided within the main body distal hard portion of the body cavity insertion portion;
a main body operation portion configured to input a curving operation to the main body curving portion;
an arm operation portion configured to input a curving operation to the curving mechanism of the treatment arm;
a branch which is provided at a proximal side of the body cavity insertion portion;
a first extension which extends from the branch toward the main body operation portion;
a second extension which is separated from the first extension in the branch and which extends from the branch toward the arm operation portion, the arm operation portion and the second extension being coupled with the main body operation portion and the first extension so that a coupled collective body is formed by the main body operation portion, the first extension, the arm operation portion and the second extension;
an operation portion integral attaching/detaching mechanism which is provided in the branch and which is configured to removably and integrally attach the coupled collective body to the body cavity insertion portion;
a first internal object which is extended toward the proximal side from the body cavity insertion portion through the operation portion integral attaching/detaching mechanism and the first extension, and which is configured to be pushed or pulled by the curving operation input via the main body operation portion to actuate the main body curving portion;
a second internal object which is extended toward the proximal side from the treatment arm through the operation portion integral attaching/detaching mechanism and the second extension, and which is configured to be pushed or pulled by the curving operation input via the arm operation portion to actuate the curving mechanism of the arm; and
an observation section attaching/detaching mechanism configured to removably attach the observation section to the body cavity insertion portion,
wherein the operation portion integral attaching/detaching mechanism includes an internal object connection portion configured to separably connect an insertion portion side part and an operation portion side part in the first internal object and the second internal object.

2. The treatment endoscope according to claim 1 , wherein the at least one treatment arm includes a treatment arm comprising a first curving mechanism configured to curve in four directions, and a second curving mechanism which is provided at a proximal side of the first curving mechanism and which is configured to curve in two directions.

3. The treatment endoscope according to claim 1 , wherein the at least one treatment arm comprises at least two treatment arms which separately curve independently of each other.

4. The treatment endoscope according to claim 1 , further comprising:
a main body operation portion attaching/detaching mechanism configured to detachably connect the main body operation portion to the first extension; and
an arm operation portion attaching/detaching mechanism configured to detachably connect the arm operation portion to the second extension.

5. The treatment endoscope according to claim 1 , wherein the branch includes a universal cord branch configured to separate a universal cord from the first extension, the universal cord being a bundle of a tubular member of an air supply/water supply tube, a power supply cable, and a signal cable that constitute a third internal object different from the first internal object and the second internal object.

6. The treatment endoscope according to claim 5 , wherein the observation section includes an imaging cable, and the treatment endoscope includes an integral universal cord in which the imaging cable and the universal cord are integrated.

7. The treatment endoscope according to claim 1 , wherein first connection ends which are connection ends of the insertion portion side parts of the first internal object and the second internal objects, are arranged side by side in the internal object connection portion, and
wherein second connection ends which are connection ends of the operation portion side parts of the first internal object and the second internal object, are arranged side by side at positions corresponding to the first connection ends.

8. A treatment endoscope comprising:
a body cavity insertion portion which includes a main body distal hard portion, and a main body curving portion provided at a proximal side of the main body distal hard portion;
at least one treatment arm which includes a curving mechanism and projects to a distal side from the main body distal hard portion of the body cavity insertion portion;
an observation section configured to image a field of view in a body cavity, the observation section including an imaging section provided within the main body distal hard portion of the body cavity insertion portion;
a main body operation portion configured to input a curving operation to the main body curving portion;
an arm operation portion configured to input a curving operation to the curving mechanism of the treatment arm;
a branch which is provided at a proximal side of the body cavity insertion portion;
a first extension which extends from the branch toward the main body operation portion;
a second extension which is separated from the first extension in the branch and which extends from the branch toward the arm operation portion;
an operation portion integral attaching/detaching mechanism which is provided in the branch and which is configured to removably attach the first extension and the second extension integrally to the body cavity insertion portion;
a first internal object which is extended toward the proximal side from the body cavity insertion portion through the operation portion integral attaching/detaching mechanism and the first extension, and which is configured to be pushed or pulled by the curving operation input via the main body operation portion to actuate the main body curving portion;
a second internal object which is extended toward the proximal side from the treatment arm through the operation portion integral attaching/detaching mechanism and the second extension, and which is configured to be pushed or pulled by the curving operation input via the arm operation portion to actuate the curving mechanism of the arm; and
an observation section attaching/detaching mechanism configured to removably attach the observation section to the body cavity insertion portion,
wherein the operation portion integral attaching/detaching mechanism includes an internal object connection portion configured to separably connect an insertion portion side part and an operation portion side part in the first internal object and the second internal object,
wherein first connection ends which are connection ends of the insertion portion side parts of the first internal object and the second internal objects, are arranged side by side in the internal object connection portion, and
wherein second connection ends which are connection ends of the operation portion side parts of the first internal object and the second internal object, are arranged side by side at positions corresponding to the first connection ends.
