Abstract

A medical apparatus main body such as a capsule main body inserted in the body cavity includes a thrust generating mechanism such as a spiral projection. The medical apparatus main body further forms an information providing unit comprising at least one of a storing unit for storing a state of the thrust generating mechanism and a direction detecting unit for detecting the direction of the medical apparatus main body. An input unit instructs a thrust generating direction of the thrust generating mechanism and thus a control unit changes continuously or the like a thrust generating state of the thrust generating mechanism based on information from the information providing unit.

Claims

1. A medical apparatus guiding system comprising:

a medical apparatus main body including an inserting portion which is adapted to be inserted into a body cavity and has an approximately cylindrical outer shape;

a thrust generating mechanism for generating a thrust in a cylindrical shaft direction, the thrust generating mechanism including a spiral structure portion arranged to a side surface of the medical apparatus main body and a rotation driving means which rotates the spiral structure portion around a cylindrical shaft of the medical apparatus main body;

storing means which stores a state of the thrust generating mechanism; and

advancing direction inputting means which inputs a change amount of an advancing direction of the medical apparatus main body,

wherein the state of the thrust generating mechanism is continuously changed based on information inputted by the advancing direction inputting means and information in the storing means, the medical apparatus guiding system further comprising;

image pick-up means arranged to the medical apparatus main body; and

display means which displays a picked up image,

wherein an operation direction of the advancing direction inputting means is allocated to up, down, right, and left sides of the image displayed on the display means,

wherein the medical apparatus main body is a capsule endoscope, and includes image rotation means which corrects rotation of the image generated upon rotating the capsule endoscope by the rotating magnetic field, and the image processed by the image rotation means is displayed on the display means.

2. A medical apparatus guiding system comprising:

a magnetic field generating device for generating a rotating magnetic field;

a medical apparatus main body including an inserting portion which is adapted to be inserted into a body cavity;

a thrust generating structure unit arranged to the medical apparatus main body;

a magnet arranged to the medical apparatus main body with a direction of magnetic pole oriented in a direction substantially orthogonal to a thrust generating direction of the thrust generating structure unit;

storing means which stores a state of the rotating magnetic field generated by the magnetic field generating device;

advancing direction inputting means which inputs a change amount of an advancing direction of the medical apparatus main body;

a control device for continuously changing the state of the rotating magnetic field based on information inputted by the advancing direction inputting means and information in the storing means;

image pick-up means arranged to the medical apparatus main body; and

display means which displays a picked up image,

wherein an operation direction of the advancing direction inputting means is allocated to up, down, right, and left sides of the image displayed on the display means,

wherein the medical apparatus main body is a capsule endoscope, and includes image rotation means which corrects rotation of the image generated upon rotating the capsule endoscope by the rotating magnetic field, and the image processed by the image rotation means is displayed on the display means.

3. The medical apparatus guiding system according to claim 2, further comprising:

advancing speed inputting means which inputs an advancing speed of the medical apparatus main body; and

control means which continuously changes the state of the rotating magnetic field based on information inputted by the advancing direction inputting means and the advancing speed inputting means and information in the storing means.

4. The medical apparatus guiding system according to claim 3, wherein at least one of the advancing direction inputting means and the advancing speed inputting means returns to a position where an operation amount is zero upon stopping operation.

5. The medical apparatus guiding system according to claim 3, wherein an operation amount of the advancing direction inputting means corresponds to a change amount of a direction of the rotating magnetic field.

6. The medical apparatus guiding system according to claim 3, wherein an operation amount of the advancing speed inputting means corresponds to a rotating frequency of the rotating magnetic field.
