Video of How Ligasure Works: Advanced Vessel Sealing Technology in Modern Surgery
In this educational video, titled "How Ligasure Works: Advanced Vessel Sealing Technology in Modern Surgery," we delve into the mechanism, applications, and surgical advantages of one of the most reliable energy platforms used in modern operating rooms—Ligasure. Whether you're a surgical resident, practitioner, or medical student, this video will help you understand why Ligasure has become an essential tool for achieving precise, consistent, and safe tissue sealing across a wide range of surgical specialties.
What Is Ligasure?
Ligasure is a bipolar electrothermal vessel sealing system that utilizes a combination of radiofrequency (RF) energy and mechanical pressure to permanently seal blood vessels and tissue bundles. Developed to enhance surgical hemostasis, Ligasure is capable of sealing vessels up to 7 mm in diameter, making it highly versatile for procedures that require bloodless dissection and secure vascular control.
How Ligasure Works (Explained in the Video)
Energy + Pressure: Ligasure uses RF energy that is delivered through bipolar electrodes. As the jaws compress the tissue, the energy is distributed evenly across the tissue planes, melting collagen and elastin to fuse vessel walls together.
Smart Feedback System: The device incorporates an intelligent tissue feedback algorithm that continuously monitors the tissue’s impedance. It automatically discontinues energy delivery once a complete and effective seal is formed, reducing the risk of overcooking or thermal injury.
Minimal Thermal Spread: The lateral thermal spread is typically less than 2 mm, making Ligasure exceptionally safe when working near delicate structures such as ureters, nerves, and bowel.
Sealing + Cutting: Many Ligasure handpieces come with integrated cutting blades, allowing surgeons to seal and divide tissue in a single step—improving procedural efficiency.
Clinical Applications
Ligasure is widely used in:
Laparoscopic hysterectomy (TLH)
Cholecystectomy
Colorectal surgery
Thyroid and parathyroid surgery
Bariatric procedures
Oncologic resections and lymphadenectomy
Its ability to consistently create strong, burst-resistant seals has made it a standard tool in both laparoscopic and open surgeries.
Benefits of Ligasure Technology
Reliable sealing of large vessels (up to 7 mm)
Reduction in operative time and blood loss
Less need for sutures or clips
Reduced risk of thermal injury to adjacent tissues
Enhanced surgical ergonomics with multifunctional handpieces
Conclusion
Ligasure is more than just an energy device—it’s a smart surgical system that combines safety, precision, and efficiency. This video provides a comprehensive look at how Ligasure works and why it remains a preferred technology among surgeons across specialties. With its ability to seal and divide tissue in a controlled and consistent manner, Ligasure has revolutionized vessel sealing and continues to shape the future of minimal access and advanced open surgeries.
