Description

LigaSure is an advanced bipolar vessel sealing device widely used in laparoscopic surgery for safe and effective hemostasis. Its ability to seal vessels up to 7 mm in diameter with minimal thermal spread has made it an essential energy source in modern minimally invasive procedures. Under the guidance and teachings of Dr. R. K. Mishra, a pioneer in laparoscopic surgery, surgeons can learn the correct technique, practical tips, and safety principles for optimal use of LigaSure. The basic principle of LigaSure lies in its feedback-controlled energy delivery system. It senses tissue impedance and delivers precise bipolar energy combined with pressure to permanently seal vessels and tissue bundles. In laparoscopic surgery, LigaSure is commonly used during procedures such as laparoscopic cholecystectomy, hysterectomy, colorectal surgery, and advanced gynecological and general surgical operations. Technique of Using LigaSure in Laparoscopy Proper technique begins with correct port placement and ergonomic positioning of the surgeon. The LigaSure handpiece should be introduced through an appropriately sized trocar to allow free movement without torque. The target tissue or vessel should be clearly visualized, gently skeletonized, and positioned between the jaws of the instrument without excessive tension. Once the tissue is grasped, the activation button is pressed and maintained until the audible or visual signal indicates complete sealing. If division is required, the built-in cutting mechanism or laparoscopic scissors can be used after ensuring a secure seal. Tips for Effective Use Dr. R. K. Mishra emphasizes that LigaSure should not be used as a blunt dissector. Adequate dissection and exposure before sealing are crucial. Surgeons should avoid sealing excessively thick tissue in a single bite; instead, tissue should be divided into smaller bundles for reliable sealing. Keeping the jaws clean, avoiding charring, and waiting for the full sealing cycle to complete improve efficiency and reduce complications. Gentle traction and counter-traction help in precise energy application. Safety Considerations Safety is paramount when using energy devices in laparoscopy. LigaSure should always be activated under direct vision to prevent inadvertent thermal injury to adjacent structures such as bowel, ureter, or major vessels. Surgeons must be aware of thermal spread and avoid activating the device near metallic clips or instruments. Regular inspection of the instrument and proper understanding of the energy settings further enhance patient safety. In conclusion, LigaSure is a powerful and reliable tool in laparoscopic surgery when used with correct technique, sound judgment, and strict adherence to safety principles. As taught by Dr. R. K. Mishra, mastering LigaSure not only improves surgical efficiency but also ensures excellent hemostasis and better patient outcomes in minimally invasive surgery.
