Abstract

A data generating device for endoscope observation includes an annular insertion simulator and a moving amount data generator. The annular insertion simulator simulates insertion of an endoscope into a subject. The moving amount data generator generates moving amount data representing a virtual moving amount of the annular insertion simulator during a simulated insertion, based on an actual operation amount of the annular insertion simulator.

Claims

1. A data generating device for endoscope observation, comprising;

an annular insertion simulator which simulates insertion of an endoscope into a subject; and

a moving amount data generator that generates moving amount data representing a virtual moving amount of said annular insertion simulator during a simulated insertion, based on an actual operation amount of said annular insertion simulator.

2. The data generating device according to claim 1, wherein said moving amount data represents a virtual moving amount of said annular insertion simulator from a reference position.

3. The data generating device according to claim 1, wherein said annular insertion simulator is an endless loop.

4. The data generating device according to claim 1, wherein a part of said annular insertion simulator is linear.

5. The data generating device according to claim 1, further comprising an operation amount detector that detects said actual operation amount of said annular insertion simulator.

6. The data generating device according to claim 5, wherein said operation amount detector detects amount of rotation of said annular insertion simulator as said actual operation amount, and said moving amount data generator generates said moving amount data by multiplying a predetermined coefficient by said amount of rotation.

7. The data generating device according to claim 1, further comprising a direction data generator that generates direction data representing a virtual direction of a virtual tip of said annular insertion simulator for observing said subject.

8. The data generating device according to claim 7, further comprising a data outputting device that outputs said moving amount data and said direction data to an external device.

9. The data generating device according to claim 7, further comprising a direction adjuster that adjusts said virtual direction.

10. The data generating device according to claim 9, wherein said direction adjuster includes an angle knob to simulate an operation for adjusting a direction of said virtual tip.

11. The data generating device according to claim 9, wherein said annular insertion simulator is provided close to said direction adjuster so that said annular insertion simulator and said direction adjuster can be operated by a user at the same time.

12. The data generating device according to claim 1, further comprising a mode selector that selects one of a first mode where said moving amount data generator generates said moving amount data based on said actual operation amount of said annular insertion simulator, and a second mode where said moving amount data generator generates said moving amount data based on a proportional operation amount of said annular insertion simulator, said proportional operation amount being proportional to said actual operation amount.

13. The data generating device according to claim 12, wherein said proportional operation amount is smaller than said actual operation amount.

14. An endoscope system comprising;

an annular insertion simulator which simulates insertion of an endoscope into a subject;

a moving amount data generator that generates moving amount data representing a virtual moving amount of said annular insertion simulator during a simulated insertion, based on an actual operation amount of said annular insertion simulator;

a position data generator that generates position data representing a position of a virtual tip of said annular insertion simulator for observing said subject, based on a predetermined reference position of said virtual tip and said moving amount data;

an image storage that stores image data of said subject; and

an image generator that generates a partial image of said subject by processing said image data;

wherein said image generator generates said partial image corresponding to a position of said virtual tip, said position being represented by said position data, and said partial image being supposed to observe.

15. The endoscope system according to claim 14, further comprising an image display that displays said partial image.
