An endoscopic system and method that is adaptable for therapeutic applications as well as sensor operation and is capable of producing 3-dimensional human vision simulated imaging with real dynamic convergence, not virtual convergence. Applications may include use in any space, including but not limited to, intra-abdominal cavities, intra-thoracic cavities, and intra-cranial cavities. Further, two or more diagnostic/sensor probes may be used, with at least two being the same kind to create the 3-dimensional effect, such as but not limited to, camera, ultrasound, and magnetic-resonance imaging. Diagnostic/sensor probes are each mounted to the end of a different arm, with the other ends of the two arms both being attached to the same hinge that allows them to turn freely on the same axis from side-to-side within a 180 degree angle range of movement on the distal end of a main tubular shaft system. Medical, as well as other applications, are contemplated.
