The LigaSure™ exact dissector is a surgical dissection device with nonstick nano-coated jaws.

A cooler option for fine dissection2

Our new LigaSure™ exaact dissector makes cutting and sealing simple.§,1

Low temperature profile 

The LigaSure™ exact dissector is designed to:

  • Cool down fast for secure and atraumatic tissue grasping¶,2
  • Stay cool over multiple activations2

Precise performance

The fine, curved jaw of the LigaSure™ exact dissector:

  • Allows for precision around critical structures‡
  • Enhances the ability to work in tight spaces‡,2
  • Maximizes the line of sight¶,2

Its jaw also applies equal force on opposing tissue planes for effective blunt dissection.

Balanced handling

Engineered for fine dissection, the LigaSure™ exact dissector offers:

  • A working length that’s optimized to provide precise control§,2
  • A cutting trigger that’s aligned with the handle, eliminating interference with the wound edge§,2

Improved efficiency

The fast-cooling times of the LigaSure™ exact dissector mean:

  • Fewer instrument exchanges#
  • More efficient procedures in the OR∆

All delivered with the speed and reliable performance of LigaSure™ vessel sealing technology.

LIGASURE

Thyroidectomy procedure using the Ligasure™ exact dissector performed by Dr. Mark S. Sneider, MD

Clinical and economic benefits for thyroidectomies

This is an icon of an analog alarm clock.

Surgical time 

LigaSure™ technology enables:

  • Generally shorter surgical time compared to clamp and tie ligation3–11
  • Shorter or comparable surgical time versus Thunderbeat™* and Harmonic™* scalpels6–8,12–17

   

See an icon to represent pain.

Protect voice function7,12 with less pain†,13

  • LigaSure™ devices have a decreased impact on voice function compared to the Harmonic™* Focus device.7
  • Patients experience less pain when swallowing following thyroidectomy.†,13

   

Save on healthcare costs.

The higher cost of LigaSure™ devices compared to suture ligation are offset by saved surgical time during thyroidectomy plus other savings,18–20 which include:

  • Reduced device costs†,8,15
  • Up to 30% decrease in OR supplies cost†,21
  • Reduced overall surgical costs compared to conventional ligation19
