ENDOSCOPIC SHAFT PROVIDED WITH MOVABLE DISTAL END

摘要

PROBLEM TO BE SOLVED: To provide a distal end structure for endoscope ensuring sufficient flexibility and sufficient rigidity when reaching a prescribed bending position and imparting a sufficient diagnostic operation feeling to an operator. SOLUTION: This endoscopic shaft comprises a movable distal end and an operation device. The operation device is connected to the distal end through the endoscopic shaft for operation. The distal end comprises a plurality of swollen bodies stacked in the longitudinal direction. Two of the swollen bodies are provided mutually in the diameter direction to form one layer, and the phase of the other layer directly adjacent to one layer is shifted by 90 deg..
