Abstract: Herein disclosed is an endoscope that includes a handle and an elongated probe having a distal end and a proximal end. The handle abuts the proximal end of the probe and includes an articulation lever. The probe also includes a vertebrae column immediately abutting the distal end, on which at least one sensor is amounted. The vertebrae column is configured to have at least two parallel groups of gaping slits, along an axial direction of the vertebrae column. Each two of the axially adjacent gaping slits come from the two groups of gaping slits respectively and are juxtaposed in circumferential positions in the respective circumferential planes. The articulation lever and the distal end are connected by pulling wires, and when the articulation lever is maneuvered, the distal end is pulled away from the axial direction, causing the vertebrae column to deflect.
