Abstract

An endoscope system includes a movement detector for detecting an operator'"'"'s movement, a signal processor for processing a signal the detector detects, and a control for controlling drive which drives a medical device according to an output signal of the signal processor. The endoscope system bends a bending section of an endoscope serving as a medical device according to the operator'"'"'s movement, and thus orients the observation field of view to a direction the operator intends or controls the movement of a treatment adapter serving as a medical device. The endoscope system includes a superimposing means for superimposing an image associated with the operator'"'"'s movement onto an image acquired by an imaging device associated with the endoscope system.

Claims

1. An endoscope system, comprising:

a medical device for applying medical care to a subject by changing at least a part of a shape of said medical device;

a driving means for actuating said medical device;

a movement detecting means, having at least one sensor for receiving signals from at least one signal source, for processing said received signals, and for detecting a movement of an operator who operates said medical device; and

a control means, operably connected to said movement detecting means, for controlling said driving means to actuate said medical device and for changing at least a part of a shape of said medical device according to said operator'"'"'s movement which is detected by said movement detecting means,

wherein said movement detecting means includes a means for detecting a movement of one of an operator'"'"'s hand and an operator'"'"'s head, and a superimposing means for superimposing an image associated with the movement of one of the hand and head on an image which an imaging means generates.

2. An endoscope system according to claim 1, wherein said movement detecting means includes a signal processing means for processing detected signals.

3. An endoscope system according to claim 1, wherein said medical device is an endoscope and said driving means is a bending drive for bending a bending section of an endoscope.

4. An endoscope system according to claim 1, wherein said medical device is a treatment adapter adapted to be routed through a treatment adapter channel of an endoscope into a subject'"'"'s body and said driving means actuates said treatment adapter.

5. An endoscope system according to claim 4, wherein said treatment adapter is a diathermic snare made up of an outer casing and a snare wire which runs through the outer casing and has a loop formed at a tip portion thereof and said driving means advances and withdraws said outer casing and said snare independently.

6. An endoscope system according to claim 1, wherein said at least one sensor of said movement detecting means is an ultrasonic sensor for detecting the positional state of an operator'"'"'s head and recognizing the operator'"'"'s movement according to the position of the operator'"'"'s head.

7. An endoscope system according to claim 1, further comprising an imaging means for generating images of a body of said subject and displaying the images on a monitor.

8. An endoscope system, comprising:

a medical device for applying medical care to a subject;

a driving means for actuating said medical device;

a movement detecting means, having at least one sensor for receiving signals from at least one signal source, for processing said received signals, and for detecting a movement of an operator who operates said medical device;

a control means, operably connected to said movement detecting means, for controlling said driving means to actuate said medical device according to said operator'"'"'s movement which is detected by said movement detecting means; and

an imaging means for generating images of a body of said subject and displaying the images on a monitor,

wherein said detecting means includes a means for detecting a movement of an operator'"'"'s hand and a superimposing means for superimposing an image associated with the movement of the hand on an image which said imaging means generates.

9. An endoscope system, comprising:

a medical device for applying medical care to a subject;

a driving means for actuating said medical device;

a movement detecting means, having at least one sensor for receiving signals from at least one signal source, for processing said received signals, and for detecting a movement of an operator who operates said medical device;

a control means, operably connected to said movement detecting means, for controlling said driving means to actuate said medical device according to said operator'"'"'s movement which is detected by said movement detecting means; and

an imaging means for generating images of a body of said subject and displaying the images on a monitor,

wherein said detecting means includes a means for detecting a movement of an operator'"'"'s hand and a superimposing means for superimposing an image associated with the movement of the hand on an image which said imaging means generates, and

wherein said control means drives said driving means to control said medical device so that said medical device operates in association with a movement of a hand.

10. An endoscope system, comprising:

a medical device for applying medical care to a subject;

a driving means for actuating said medical device;

a movement detecting means, having at least one sensor for receiving signals from at least one signal source, for processing said received signals, and for detecting a movement of an operator who operates said medical device;

a control means, operably connected to said movement detecting means, for controlling said driving means to actuate said medical device according to said operator'"'"'s movement which is detected by said movement detecting means; and

an imaging means for generating images of a body of said subject and displaying the images on a monitor,

wherein said detecting means includes a means for detecting a movement of an operator'"'"'s hand and a superimposing means for superimposing an image associated with the movement of the hand on an image which said imaging means generates, and

wherein said means for detecting a movement of a hand includes a data glove.
