New Shears Offer Improved Surgical Performance

The shears can be used for procedures where precise dissection and efficiency are vital, including thyroidectomies, parotidectomies, and axillary dissections, allowing surgeons to precisely dissect, grasp, coagulate, and cut without exchanging instruments. The small (nine centimeter), light hand piece also seals five-millimeter vessels, as well as lymphatics, and offers advantages in terms of efficiency, performance, and safer dissection near vital structures, when compared to electro-surgery. The Harmonic Focus curved shears is a product of Ethicon Endo-Surgery (EES, Cincinnati, OH, USA), a Johnson & Johnson company (New Brunswick, NJ, USA).

"A significant benefit of the Harmonic Focus curved shears is the minimal thermal spread, which is important to help reduce the risk of nerve injury for patients,” said Peter Angelos, M.D., Ph.D, of the University of Chicago (IL, USA).

Harmonic devices use ultrasonic energy to simultaneously cut and coagulate soft tissue and vessels at much lower temperatures than radiofrequency (RF) based devices, resulting in minimal thermal damage to the surrounding tissue. Since there is no electrical current on the active blade of the device, there is no electrical energy being transferred to or through the patient.
