Introduction
The ForceTriad energy platform is designed to provide RF energy for monopolar and bipolar surgical applications and tissue-fusion applications. It features three touchscreen user interfaces, and has the ability to automatically detect handsets and configure the energy platform accordingly. Safety and diagnostic functionality include automatic failsafe functions. The Covidien ForceTriad energy platform, patient return electrodes, and active instruments are designed to work as a system. Covidien offers a selection of patient return electrodes and active instruments that are fully compatible with this energy platform. When considering other manufacturers’ patient return electrodes and/or active instruments, customers should seek detailed user instructions and warning information from the manufacturer.
Overview and General Features
Introduction
Indications for Use The ForceTriad is a full-featured electrosurgical generator intended for open and laparoscopic surgical procedures where the surgeon requires electrosurgical cutting (resecting, dividing, or separating), coagulation (hemostasis, coagulating, or desiccating), or vessel sealing (sealing or fusing). The generator is intended for use in general, laparoscopic, and gynecologic surgical procedures where ligation of vessels, pulmonary vasculature, or lymph vessels, is desired. The system creates a vessel ligation (seal) by the application of bipolar electrosurgical RF energy (coagulation) to vessels interposed between the jaws of the device. The generator can also be used with standard bipolar devices where bipolar cutting or coagulation is desired or with compatible resectoscopes for endoscopically controlled removal (resection) or coagulation of tissue using 0.9% NaCl solution (saline) as the irrigation medium. The indications for use include general (including urologic, thoracic, plastic, and reconstructive), laparoscopic, and gynecological procedures where electrosurgical cutting and coagulation of tissue, and sealing (fusion) of vessels, including pulmonary vessels, and tissue bundles is performed, including such procedures as bowel resections, hysterectomies (both vaginal and abdominal), laparoscopic cholesystectomies, laparoscopically assisted vaginal hysterectomies, gall bladder procedures, Nissen fundoplication, adhesiolysis, oophorectomy, etc. The devices can be used on vessels (arteries, veins, pulmonary arteries, pulmonary veins, lymph) up to 7mm and bundles as large as will fit in the jaws of the instruments. The LigaSure tissue fusion function has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures. Do not use this function for these procedures. For warnings and specific contraindications for instruments used with the ForceTriad energy platform, refer to each instrument’s instructions for use (IFU).

ForceTriad Energy Platform User’s Guide
Power Modes
The ForceTriad energy platform produces five modes of power output.
Cut Modes Pure cut provides a clean, precise cut in any tissue with little or no hemostasis. Blend cut is a conventional blended waveform that provides slower cutting with simultaneous hemostasis.
Overview and General Features
Monopolar Modes
Valleylab Mode Valleylab mode is a unique combination of hemostasis and dissection that allows the user to slow down for more hemostasis and speed up for faster dissection. Thermal spread is equal to or less than Cut or Blend modes.
Coag Modes Fulgurate coagulates tissue by sparking from the active electrode, through air, to the patient tissue. Since sparks may spray unpredictably from the electrode during fulguration, using fulguration for delicate tissue or in confined areas can complicate surgery. Accidental sparking to adjacent areas can occur as tissue at the surgical site dries and becomes more resistant to current flow. Spray delivers wider fulguration; penetration is shallower and the affected tissue area is larger than with the Fulgurate mode.
Bipolar Modes Three bipolar modes are available: Low, Standard, and Macrobipolar. Low delivers precision and fine control over the amount of desiccation. Standard is a conventional bipolar output at low voltage. Macro (Macrobipolar) may be used for bipolar cutting or rapid coagulation. Power remains constant over a wide range of tissue types.
Autobipolar The autobipolar feature senses tissue impedance between the two bipolar electrodes, then uses the impedance information to automatically start or stop bipolar RF energy delivery. Optionally, the user may choose between footswitch start and auto start, or program a delay between auto start and RF activation. Note: When using autobipolar mode, the tissue in the grasp of the bipolar device must have an impedance in the range of 20 W -1000 W. The activation impedance safety feature will not deliver RF power to the tissue if it is not within the specified range. This is a factory-set value that cannot be reset by the user.

Power Modes
LigaSure Mode The LigaSure tissue-fusion mode can be used on arteries, veins, pulmonary vasculature, and lymphatics up to and including 7 mm in diameter and tissue bundles. This system provides precise energy delivery and electrode pressure to vessels for a controlled time period to achieve a complete and permanent fusion of the vessel lumen. The system has been designed to produce minimal sticking, charring, or thermal spread to adjacent tissue. Warning Do not attempt to fuse lung tissue with LigaSure mode or instruments.
LigaSure Instruments The LigaSure instruments that complete the ForceTriad tissue-fusion system include multiple reusable and single use instruments for open and laparoscopic procedures. Each reusable instrument requires a corresponding single-use electrode. The LigaSure function is only available when using Covidien LigaSure instruments.
