Abstract

An endoscope device of the invention includes: an insertion portion disposed with an observation optical system; an operation portion continuously provided to a proximal end side of the insertion portion; a display device main body provided to a proximal end side of the operation portion and disposed with a monitor portion for displaying a subject image; a rotational movement shaft for rotationally movably journaling the display device main body with respect to the operation portion; and a finger-hooking portion provided to the display device main body and for operation of rotationally moving the display device main body about a rotational movement shaft, and thus it is possible for an operator to easily orient the monitor of the display device in an easily viewable direction when operatably grasping the operation portion.

Claims

1. An endoscope device comprising:

an insertion portion disposed with an observation optical system;

an operation portion continuously provided to a proximal end side of the insertion portion;

a display device main body provided to the proximal end side of the operation portion, the display device main body being disposed with a monitor for displaying a subject image;

a rotational movement shaft for rotationally movably journaling the display device main body with respect to the operation portion; and

a finger-hooking portion provided to the display device main body, the finger-hooking portion being used to operate to rotationally move the display device main body about the rotational movement shaft.

2. The endoscope device according to claim 1, wherein the insertion portion comprises a bending portion that is bendable in a predetermined direction.

3. The endoscope device according to according to claim 2, wherein the bending portion is operated with a bending operation portion provided on a predetermined side-surface side of the operation portion and on a side closer to the insertion portion than the finger-hooking portion, the bending operation portion being rotationally movable about a shaft that is generally parallel to the rotational movement shaft.

4. The endoscope device according to claim 3, wherein the finger-hooking portion protrudes from a surface of the display device main body, the surface being provided with the monitor, toward the predetermined side-surface side, the finger-hooking portion including a protruding surface having a surface that is generally parallel to the rotational movement shaft.

5. The endoscope device according to claim 4, wherein the protruding surface is formed by a plane surface.

6. The endoscope device according to claim 4, wherein the protruding surface is formed by a curved surface.

7. The endoscope device according to claim 4, wherein the protruding surface is formed by a plurality of surfaces.

8. The endoscope device according to claim 4, wherein

the finger-hooking portion includes a finger-hooking surface on which a user hooks a finger to operate to rotationally move the device main body, the finger-hooking surface being disposed continuously from the protruding surface;

and

the finger-hooking portion includes a convex portion.

9. The endoscope device according to claim 4, wherein the finger-hooking portion is disposed to protrude farther than the bending operation portion relative to the operation portion.

10. The endoscope device according to claim 1, wherein the finger-hooking portion has a predetermined dimension in both left and right directions sandwiching a center axis in a longitudinal direction of the operation portion.

11. The endoscope device according to claim 1, wherein the finger-hooking portion is provided with a switch for performing a functional operation of the display device main body.

12. The endoscope device according to claim 11, wherein the switch is disposed at a position that causes a direction of pressing operation of the switch to intersect with a center of the rotational movement shaft.

13. The endoscope device according to claim 3, wherein the finger-hooking portion and the bending operation portion are disposed at positions that prevent mutual interference therebetween in respective rotational movement range.

14. The endoscope device according to claim 13, wherein a back surface of the finger-hooking portion is a contact portion that comes in contact with the operation portion when the display device main body is rotationally moved to a raised position thereof.

15. The endoscope device according to claim 1, wherein the endoscope device comprises a housing portion in which to build a battery for supplying an electric power at least to the monitor.

16. The endoscope device according to claim 15, wherein the housing portion is provided to the display device main body.

17. A display device comprising:

a monitor;

a device main body rotationally movably connected to an endoscope; and

a finger-hooking portion extendedly provided to the device main body, the finger-hooking portion being for operating a rotational movement relative to the endoscope.

18. The display device according to claim 17, wherein the finger-hooking portion comprises a protruding surface extended from a surface of the display device, the surface being provided with the monitor.

19. The display device according to claim 18, wherein the protruding surface is formed by a plane.

20. The display device according to claim 18, wherein the protruding surface is formed by a curved surface.

21. The display device according to claim 18, wherein the protruding surface is formed by a plurality of surfaces.

22. The display device according to claim 18, wherein

the finger-hooking portion includes a finger-hooking surface on which a user hooks a finger to operate to rotationally move the device main body, the finger-hooking surface being disposed continuously from the protruding surface;

and

the finger-hooking portion includes a convex portion.

23. The display device according to claim 17, wherein the finger-hooking portion is provided with a switch for performing various functional operations.
