Control Knob Set UD/RL

The Control Knob Set UD/RL refers to the control knob assembly used to control the up/down and left/right bending angles of the endoscope tip.

Rotating these two large knobs pulls on the wires, thereby remotely controlling the up, down, left, and right bending of the endoscope tip inserted into the human body, allowing for observation of different angles and manipulation of instruments.
