Flexible endoscope with detachable head and handle

A flexible endoscope system, comprising:

• (i) a head part, comprising:
• a shaft (2);
• at least one drive tendon (4) extending in the shaft (2);
• a flexible tip (2A) located at a distal end of the shaft (2), movement of the flexible tip being controlled by the drive tendon (4);
• and
• a connecting interface (3) located at a proximal end of the shaft (2), the connecting interface including at least one capstan assembly (31) around which the drive tendon (4) is wound;
• an image censor module (21) arranged on the flexible tip (2A);
• and
• (ii) a control handle (1) detachably connected to the connecting interface (3);
• wherein the capstan assembly (31) includes a capstan shaft (311) having a first docking key (32), and the control handle includes a second docking key (13), when the control handle (1) is coupled to the connecting interface (3), the second docking key (13) mates with the first docking key (32) such that movement of the second docking key can be transmitted to the capstan assembly via the first docking key to adjust the tension in the drive tendon (4).
