Disposable endoscope
The present invention relates to an intubation system comprising insertion unit to be connected to a bending section of a medical instrument comprising an inner elongated shaft structure being capable of torque transmission around its length axis and an outer elongated shaft structure surrounding the inner elongated shaft structure and having a continuous outer surface, and an orientation controller being attached to the inner elongated shaft, such that when the orientation controller rotates, the bending section turns around itself.
1. An orientation controller to be connected to an insertion unit of an endoscopic device having a rotatable bending section; said controller comprises:
a handle defining an axial direction to be handled by an operator;
a rotatable bearing structure connecting between the handle and the insertion unit;
wherein said rotatable bearing structure is configured and operable to rotate the rotatable bending section of the insertion unit about the axial direction; and
a mode selector capable of operating the endoscopic device in having a locked mode and unlocked operation modes, wherein operation of the locked operation mode blocks the rotatable bearing structure, and operation of the unlocked mode allows the operator to rotate the rotatable bending section by rotating the rotatable bearing structure about the axial direction;
wherein, when the insertion unit comprises an inner elongated shaft structure and an outer elongated shaft structure surrounding the inner elongated shaft structure; said rotatable bearing structure comprises an inner rotatable bearing element being configured for holding the inner elongated shaft structure, and an outer rotatable bearing element connected to the outer elongated shaft structure such that the inner rotation bearing element is capable of rotating within the outer rotatable bearing element, thereby rotating in the unlocked operation mode the rotatable bending section around itself without changing the outer elongated shaft structure's position inside the body lumen.
2. The orientation controller of claim 1 , wherein in the unlocked mode in which the rotation is made by rotating the rotatable bearing structure, said mode selector is configured to release the rotatable bearing structure.
3. The orientation controller of claim 1 , wherein said rotatable bearing structure comprises a gear mechanism, wherein said outer rotatable bearing element comprises an outer wheel configured to block rotation of rotatable bearing structure upon operation of said mode selector, and said inner rotatable bearing element comprises an inner wheel configured to be capable of free rotation by the outer wheel and to hold an extremity of the rotatable bending section, such that in a locked operation mode, rotation of the orientation controller rotates said inner elongated shaft structure inside said outer elongated shaft structure, and in an unlocked mode, rotation of the outer wheel rotates the inner elongated shaft structure via the inner wheel inside the outer elongated shaft structure.
4. The orientation controller of claim 3 , wherein said gear mechanism is configured to allow free rotation between the outer elongated shaft structure and the inner elongated shaft structure; said gear mechanism further comprises an outer shaft holder configured to hold an extremity of the outer elongated shaft structure, wherein said inner wheel is configured to hold an extremity of the inner elongated shaft structure.
5. An intubation system comprising an insertion unit to be connected to a bending section of a medical instrument and an orientation controller as defined in claim 1 .
6. The intubation system of claim 5 , wherein said insertion unit comprises an inner elongated shaft structure being capable of torque transmission around its length axis and an outer elongated shaft structure surrounding the inner elongated shaft structure and having a continuous outer surface.
