The three-lumen PEEK capillary tube has been applied in minimally invasive gastrointestinal surgery. Gastrointestinal radiofrequency ablation surgical instruments are a new type of minimally invasive surgical instrument. Designers used the structure and material of the three-lumen PEEK tube to ensure the effectiveness of the instrument. The three holes in the PEEK three-lumen tube are respectively used for: 1. cooling water, 2. sensor, and 3. electrode circuit.
PEEK material, with its excellent temperature resistance and insulation properties, as well as its rigidity and toughness, allows for good guidance, bringing good news to patients undergoing radiofrequency ablation surgery in the gastrointestinal tract and other organs.
