Abstract

A manipulator comprises a hollow shaft, wires provided on the shaft and a working unit disposed on one end of the shaft and being driven by at least one wire of the wires, the working unit having a tip tool including a rolling mechanism which rotates about an axis Or directed to a distal end thereof. A tip side surface of a proximal end member and a cover of a distal end member are relatively rotated by the rolling mechanism. The cover has a rotation identifier for indicating a degree of relative rotation of the tip side surface. The tip side surface has an alignment indicator for indicating an initial position of the cover.

Claims

1. A manipulator for medical use comprising:

a hollow shaft;

a power transmitting member disposed on said shaft; and

a working unit disposed at one end of said shaft and being driven by said power transmitting member, said working unit having a tip tool including a rolling mechanism rotating about an axis directed to a distal end thereof;

wherein a proximal end member and a distal end member are relatively rotated by said rolling mechanism, and a rotation identifier is provided on at least one member of the proximal end member and the distal end member, said rotation identifier indicating a degree of rotation of another member.

2. A manipulator according to claim 1, wherein said other member has an alignment indicator for indicating an initial position of said one member.

3. A manipulator according to claim 1, wherein said rotation identifier comprises a triangular shape.

4. A manipulator according to claim 3, wherein a plurality of said triangular shapes are provided, and said triangular shapes are arranged such that sides of said triangular shapes are aligned with each other along a rolling direction of said rolling mechanism.

5. A manipulator according to claim 3, wherein a plurality of said triangular shapes are provided, and said triangular shapes are coupled with each other in series along a rolling direction of said rolling mechanism.

6. A manipulator according to claim 5, wherein said triangular shapes are disposed at equal intervals along the rolling direction.

7. A manipulator according to claim 5, wherein said triangular shapes are different from each other in shape.

8. A manipulator according to claim 5, each of said triangular shapes has an identifiable mark.

9. A manipulator according to claim 1, wherein said rotational identifier comprises recesses or protrusions.

10. A manipulator according to claim 1, wherein said rotational identifier comprises colors or patterns.

11. A manipulator according to claim 1, wherein said proximal end member includes a main shaft.

12. A manipulator according to claim 1, wherein said distal end member includes a cover.
