Soft Tissue Dissection Devices

Breast, ENT, Orthopaedic, Spinal, Neurological, and General Surgical Applications


The PlasmaBlade™ soft tissue dissection device uses brief, precise pulses of radiofrequency (RF) energy to cut and coagulate soft tissue. RF energy, combined with a proprietary insulation technology, enables the PlasmaBlade to dissect with the precision of a scalpel, and the bleeding control of traditional electrosurgery, while producing minimal thermal damage to surrounding tissue. Clinical research has demonstrated that low thermal injury technology offers intra-operative and post-operative benefits when compared to the current standard of care — scalpel and traditional electrosurgery.1,2,3


The PlasmaBlade is indicated for cutting and coagulation of soft tissue during General, Plastic and Reconstruction (including but not limited to skin incisions and development of skin flaps), ENT, Gynecologic, Orthopaedic, Arthroscopic, Spinal and Neurological procedures.

Observed Benefits

Lower temperature

  • 64% average reduction in blade temperature for similar CUT settings compared to traditional electrosurgery1
  • 45% average reduction in blade temperature for similar COAG settings compared to traditional electrosurgery1

Incision healing

  • Equivalent cutaneous healing to scalpel5,*
  • Significantly reduced thermal injury depth and scar width compared to traditional electrosurgery1

Increased efficiency

  • Maintains cutting effectiveness and hemostatic ability even when submerged in liquefied tissue or blood, unlike traditional electrosurgical tools7

Reduced surgical smoke

  • Less surgical smoke,8 allowing for increased visibility

Reduced risk

  • Eliminates risk of inadvertent scalpel injury
