LIGASURE™ FAST FACTS

LigaSure™ technology has been used in more than 4 million procedures worldwide.

There are well over 200 published peer-reviewed studies on LigaSure™ technology.

TissueFect™ sensing technology monitors changes in tissue impedance 3,333 times a second, and adjusts energy output accordingly to deliver the appropriate amount of energy for the desired tissue effect.

Valleylab™ mode is responsive energy that helps surgeons manage the tissue effect of surgical devices.

LigaSure™ technology can fuse vessels, including pulmonary vasculature*, up to and including 7 mm, lymphatics and tissue bundles with an average seal cycle of two to four seconds* (*when used with the ForceTriad™ energy platform).

Hemorrhoidectomy

The term “hemorrhoids” refers to clinical situations in which hemorrhoid cushions are abnormally enlarge or inflamed and cause symptoms. Hemorrhoidal symptoms are divided into internal and external sources. Internal hemorrhoids do not cause cutaneous pain, as they are above the dentate line and are not innervated by cutaneous nerves. When enlarged and inflamed, they can bleed, prolapse, and cause sphincter spasm and perianal irritation. External hemorrhoids are susceptible to cutaneous pain as they are covered by anoderm and may create problems with hygiene.

Surgical options for internal hemorrhoids include excision of the enlarged cushions (hemorrhoidectomy) or repositioning of the cushions with staples (hemorrhoidopexy or Procedure for Prolapse and Hemorrhoids, known as PPH). Excision is the recommended treatment for external hemorrhoids.

    Internal hemorrhoid grading

  • 1st degree: No prolapse
  • 2nd degree: Prolapse occurs during bowel movement and spontaneously returns when straining ceases
  • 3rd degree: Prolapse is manually reducible
  • 4th degree: Prolapse is irreducible
