Abstract

An endoscope device is provided which includes a manipulation portion and an inserted portion connected thereto, and an endoscope holder is provided at an elevated position, for example, on a ceiling. The endoscope device is rotatably suspended from the endoscope holder with its inserted portion extending downward. The endoscope holder has an endoscope manipulation unit for operating the endoscope device and peripheral equipment.

Claims

1. An endoscope holder comprising:

an arm member including a holding portion near a distal end portion of said arm member for holding an endoscope such that an inserted portion of the endoscope is extended downward, said holding portion holding a proximal end portion of the endoscope from a direction that intersects with a longitudinal axis of the inserted portion;

a rotating member arranged in the holding portion for rotating the endoscope held by the holding portion around the longitudinal axis of the inserted portion; and

a manipulation portion, which is provided on the distal end portion of the arm member such that the manipulation portion extends away from the arm member beyond the holding portion, for manipulating the endoscope held by the holding portion;

wherein the endoscope held by the holding portion is rotated by the rotating member with respect to the manipulation portion around the longitudinal axis of the inserted portion.

2. An endoscope holder according to claim 1, wherein said holding portion is suspended from a control box having a light source video unit and an air and water supply and suction unit.

3. An endoscope holder according to claim 2, wherein said control box is installed on a ceiling.

4. An endoscope holder according to claim 2, wherein said control box is installed on a horizontal portion of a frame.

5. An endoscope holder according to claim 2, wherein said control box comprises a built-in housing device around which a flexible tube is wound for delivery, and wherein the flexible tube comprises a light guide fiber, a signal line, an air and water supply and a suction tube.

6. An endoscope holder according to claim 5, wherein said housing device comprises a gravity balancer for urging said flexible tube in a winding direction.

7. An endoscope holder according to claim 1, wherein said holding-portion has an articulated structure, and wherein an articulated portion of the holding portion has an electromagnetic clutch brake.

8. An endoscope holder according to claim 1, wherein said holding portion has a gravity balancer for balancing the endoscope.

9. A medical apparatus comprising:

an endoscope;

an endoscope holder having a holding portion for rotatably supporting the endoscope such that an inserted portion of the endoscope is extended downward; and

a manipulation portion for manipulating the endoscope;

wherein said endoscope holder is provided on one armrest portion of a chair and said manipulation portion is provided on another armrest portion of the chair.

10. A medical apparatus comprising:

an endoscope;

an endoscope holder having a holding portion for rotatably supporting the endoscope such that an inserted portion of the endoscope is extended downward;

wherein the endoscope comprises a manipulation portion connected to the inserted portion;

wherein said inserted portion comprises a branched portion at a proximal end thereof,

wherein the manipulation portion comprises a curving manipulation portion, and

wherein the curving manipulation portion is provided on a first one of the branches of the branched portion via a flexible cord, and a second one of the branches has external devices connected thereto via a universal cord.

11. A medical device according to claim 10, wherein said external devices are a light source video unit, an air and water supply unit and suction unit, and a motor control unit.

12. A medical device according to claim 11, wherein the air and water supply and suction line are inserted through the manipulation portion, and wherein the manipulation comprises means for blocking said line.

13. A medical device according to claim 10, wherein said flexible cord comprises at least a signal line and a forceps channel, and wherein said universal cord comprises at least a signal line and an air and water supply and suction line.

14. A medical device according to claim 10, wherein said manipulation portion and said inserted portion of the endoscope are adapted to be disconnected from each other together with angle wires and signal lines, and wherein the signal lines are set to be longer than the angle wires.

15. A medical device according to claim 10, wherein said manipulation portion comprises a first forceps hole formed therein, and wherein said branched portion has a second forceps hole formed therein.

16. A medical device according to claim 10, wherein:

said inserted portion comprises a curved tube portion including a curving mechanism and angle wires inserted therethrough for curving the curving mechanism,

said manipulation portion comprises an actuator for drawing said angle wires to manipulate said curving mechanism so as to curve said curved tube portion, and said curving manipulation portion controls said actuator, and

wherein the endoscope comprises control means for detecting a state of said curved tube portion based on sensor outputs from a tension sensor for detecting tension of said angle wires and a displacement sensor for detecting displacement of said angle wires.

17. A medical device according to claim 16, wherein said tension sensor is provided at a tip portion of said inserted portion in correspondence with the angle wires and has a tip portion of the angle wires connected thereto.

18. A medical device according to claim 16, wherein said displacement sensor is provided at a tip portion of a flexible tube portion of said inserted portion in correspondence with the angle wires and has a middle portion of the angle wires inserted therethrough.

19. A medical device according to claim 16, wherein said control means calculates a difference between a tension detected by the tension sensor and a tension measured during normal curving, and feeds back to said curving manipulation portion a force corresponding to the difference.
