Q1: What is the material of the Hemolok clips, and what are its advantages?
A: The Hemolok clips are manufactured from high-quality POM (polyoxymethylene), a polymer material with excellent biocompatibility and mechanical properties. The advantages of this material include: (1) Excellent biocompatibility with minimal tissue reaction, reducing the risk of inflammation or adhesion formation; (2) Radiolucency, enabling clear postoperative imaging without artifacts that could obscure the surgical site; (3) Resistance to corrosion and degradation, maintaining mechanical integrity over time; (4) Appropriate flexibility and strength for secure vessel ligation without crushing or damaging the vessel wall. The polymer construction also eliminates the risk of clip migration or tissue reaction associated with some metal clips.

Q2: What is the difference between the three clip sizes, and how do I select the appropriate size?
A: The three clip sizes are differentiated by their ligation scope (maximum tissue thickness accommodated) and applicable vessel diameter range. The Small (ZBJ-S-6) clip has a ligation scope of 3–10 mm and accommodates vessels 1–3 mm in diameter, suitable for delicate vessels and pediatric procedures. The Medium (ZBJ-M-6) clip has a ligation scope of 5–13 mm and accommodates vessels 2–7 mm in diameter, suitable for most general surgical vessel ligations. The Large (ZBJ-L-6) clip has a ligation scope of 7–16 mm and accommodates vessels 3–10 mm in diameter, suitable for larger vascular structures. Selection should be based on the vessel diameter, with the clip chosen to provide secure occlusion without excessive compression. We recommend using the smallest clip that will adequately accommodate the vessel.

Q3: Can the Hemolok clips be used in laparoscopic and open surgery?
A: Yes, the Hemolok Clip System is suitable for both laparoscopic and open surgical procedures. The clips are designed for use with 5 mm and 10 mm trocars, making them ideal for minimally invasive approaches, while the applier handles are also suitable for direct use in open surgery. The clips are compatible with standard laparoscopic instruments and can be used in a wide range of surgical specialties, including general surgery, gynecology, urology, thoracic surgery, and pediatric surgery.

A: The elastic hinge design provides two significant advantages. First, it allows for flexible adjustment before final closure, enabling surgeons to reposition the clip if necessary before committing to the ligation. This reduces the risk of improper clip placement and improves surgical precision. Second, it provides the option to remove the clip after closing if required, offering flexibility in complex surgical scenarios where the clip may need to be repositioned or removed. The hinge design also ensures consistent, reliable closure force distribution across the entire clip, providing secure hemostasis without crushing the vessel wall.

Q5: What is the recommended storage condition and shelf life for the Hemolok clips?
A: The Hemolok clips are supplied sterile in their original packaging and should be stored in a cool, dry environment away from direct sunlight and extreme temperatures. The shelf life is typically 3–5 years from the date of manufacture, as indicated on the product labeling. We recommend checking the expiration date before use and disposing of any expired products.
