Endoscopy Knob

The knob on medical endoscopes—commonly referred to as the angle knob or bending knob—typically consists of a large knob and a small knob. By pulling on internal metal wires connected to these knobs, the rotational movements of the fingers are precisely translated into up-down and left-right deflections of the flexible tip, enabling precise control over the direction of movement at the endoscope’s tip. This allows the endoscope to navigate and locate itself effortlessly within complex human body cavities. The angle knob is a hallmark, core component found in all flexible endoscopes equipped with active bending capabilities.

Product Description

The knob on medical endoscopes—commonly referred to as the angle knob or bending knob—typically consists of a large knob and a small knob. By pulling on internal metal wires connected to these knobs, the rotational movements of the fingers are precisely translated into up-and-down, left-and-right deflections of the flexible tip, enabling precise control over the direction of the endoscope’s tip movement. This allows the endoscope to navigate and locate itself effortlessly within complex human body cavities. The angle knob is a hallmark, core component of all flexible endoscopes equipped with active bending capabilities. Its applications are extremely broad, covering nearly all major types of flexible endoscopes, including:
Digestive endoscopy: such as gastroscopy, colonoscopy, and duodenoscopy, used for navigating and observing the long digestive tract.
Respiratory endoscopy: such as bronchoscopy, used for navigating within the highly branched airways.
Urological endoscopy: such as flexible ureteroscopy, used to access the renal collecting system.
