When inserting biopsy forceps or other instruments through the working channel of a flexible endoscope (e.g., gastroscope or colonoscope), it’s critical to ensure the distal tip is in a straight position.
🚫 Inserting tools while the distal end is bent can cause:
Mechanical stress
Microtrauma to the channel lining
Long-term functional damage
✅ Tip for safe practice:
Always return the endoscope to a neutral, straightened configuration before inserting or advancing any accessory.
