Thoracic surgery

Manage stress, 
increase confidence

Thoracic surgery:
The main challenges

Prolonged air leaks (PALs) from an unstable staple line occur in up to one in four lung resections1 — increasing the risk of postoperative complications, longer hospital stays, and increased morbidity. The risk of vascular injury is higher in more complex surgeries and can result in significant blood loss, prolonged surgery, and the need to repair the injury.

Thoracic surgeons can be confident that our portfolio of Tri-Staple™ technology and surgical energy devices, will deliver key clinical benefits for them and their patients.

The confidence to navigate
complex procedures with ease

In the challenging high-pressure environment of the OR, thoracic surgeons need to be confident that they can handle any challenge. Tri-Staple™ technology reloads have a stepped cartridge face that delivers graduated compression and three rows of varied height staples. This provides superior strength and leak resistance2,3,†,‡ while generating less stress on tissue during compression and clamping.4,5,§,Ω

Products that enhance outcomes
Reinforced reloads with Tri-Staple™ technology

Preload confidence and strengthen staple lines. Reinforced reloads with Tri-Staple™ technology provide:

  • A significant reduction in the likelihood of air leaks in pulmonary lobectomies6,††
  • 50% fewer postoperative air leaks compared to nonbuttressed reloads in pulmonary lobectomies6,††
  • 41% fewer patients required a chest tube7,‡‡

Signia™ small diameter reload

For greater access to intricate vascular structures, Signia™ small diameter reload provides:

  • 10 times less tension on vessels during clamping8,†,§§
  • 30% greater access than the Ethicon Flex™* powered vascular stapler9,ΩΩ
  • 49% reduction in distal tip motion during firing, which may produce less trauma to surrounding tissues10,†,†††
  • Superior hemostasis11, ‡‡‡, §§§

Unlike other endoscopic reloads with Tri-Staple™ technology, Signia™ small diameter reloads deliver 2, double staggered rows of staples.

LigaSure™ Maryland thoracic jaw device

Trust in confidence

Delicate thoracic tissue requires a strong seal to prevent vascular injury. LigaSure™ Maryland thoracic jaw is a multifunctional device with the benefits of a Maryland dissector, grasper, and cold scissors combined with the safety of LigaSure™ technology.12,13

  • Significantly higher burst pressure on large pulmonary vessels sealed with the LigaSure™ Maryland jaw thoracic device LF1930T (297 mmHg) is 13% higher than the average for Harmonic Ace™ +7 (258 mmHg)14,†,ΩΩΩ,††††,‡‡‡‡
  • The first minimally invasive advanced energy device specifically indicated for sealing pulmonary veins and arteries/vessels up to, and including, 7mm15,ΩΩΩΩ
