This video demonstrates LigaSure vessel sealing technology works by applying a precise amount of bipolar energy and pressure to fuse the collagen and elastin in the vessel walls. It effectively seals vessels 1 to 7 mm in diameter with minimal sticking, charring, or thermal spread.
Ligasure is a surgical instrument that uses radiofrequency energy to cut and seal blood vessels and tissue during surgical procedures. It is commonly used in laparoscopic, robotic, and open surgeries as an alternative to traditional surgical instruments such as scissors and electrocautery. Here is how the Ligasure works:
-
Radiofrequency technology: The Ligasure consists of a handpiece and a generator. The handpiece contains two parallel plates that apply radiofrequency energy to the tissue between them. The energy causes the tissue to denature and fuse together, sealing the blood vessels and tissue.
-
Sealing and cutting: The Ligasure is capable of sealing vessels up to 7mm in diameter and cutting tissue up to 20mm in thickness. The device is designed to provide both sealing and cutting capabilities in a single instrument.
-
Precision and control: The Ligasure provides surgeons with precise control over tissue during surgery. The device produces minimal thermal damage to surrounding tissue, resulting in faster healing and reduced scarring.
-
Safety features: The Ligasure has safety features such as automatic shut-off to prevent overheating, and visual and audible feedback to indicate when sealing is complete.
The Ligasure has several advantages over traditional surgical instruments, including reduced blood loss, less tissue damage, faster healing, and reduced risk of infection. It is important for surgeons to receive proper training and follow manufacturer's instructions when using the Ligasure to ensure the best possible outcomes for patients.
While the Ligasure has many advantages in surgical procedures, there are also some potential disadvantages that should be considered. Here are a few possible disadvantages:
-
Cost: The Ligasure is a more expensive surgical tool than traditional surgical instruments, which may make it less accessible in some healthcare settings.
-
Learning curve: Proper training and experience are required to use the Ligasure effectively, and it may take some time for surgeons to become comfortable with the technology.
-
Limited indications: While the Ligasure can be used in many surgical procedures, it may not be suitable for all types of tissue or procedures. Some types of tissue may be more difficult to cut and seal using the radiofrequency technology.
-
Risk of injury: As with any surgical instrument, there is a risk of injury to the patient or surgeon if the Ligasure is not used properly. The radiofrequency energy can cause tissue damage if used for too long or in the wrong area.
-
Maintenance: The Ligasure requires regular maintenance, including blade sharpening and replacement, to ensure it functions properly and safely.
It is important for healthcare providers to carefully consider the potential advantages and disadvantages of the Ligasure when selecting surgical tools for a given procedure. They should also follow proper training and maintenance protocols to ensure safe and effective use of the technology.
