  • the tip section (101) is moving or bended, using bending section (104), the entire tip is moving and as a result the whole sensor's image is moving as well without the option of changing the directions of the cameras relatively to each other.
  • the present invention provides an endoscope having one or more maneuvering section such as bending, rotating or angulating sections. In this configuration each sensor may be operated independently and as a result a dynamic field of view may be obtained.
