A. GENERAL DESCRIPTION

6SENSE Technology:
This is a recent innovation in field of advance feedback controlled Electrosurgical technology
System maintains the set power by sensing- voltage, current, power, tissue density, patient return
electrode monitoring and leakage RF current- at 4000 times per second.

Minimizes dragging of electrodes in different tissues.

No need to change the power setting as the tissue changes.
 Less thermal damage by 50% than standard ESU‟s hence improves the patient recovery
time.

Reduces the risk of collateral tissue damage.

Reduces noise in other OT equipments.

Reduces the risk of neuro-muscular stimulation.

Less charring and sparking hence precise & clean cutting.

Smart ENDO Cut:
For polypectomy & papillotomy cutting is intelligently divided in cut & pause in such a way that
coagulation occurs in each pause. The system is smart to change the pause interval as tissue
density changes. Hence produces fine cutting with coagulation effect.
Smart Endo Cut: Change in cut & pause as tissue demands, dependent on the tissue impedance.

Randomized Spray Coag: The real spray : In conventional spray coag, beam tends to follow the
same path left by previous spark. Hence no homogeneous coagulation over larger area. By
randomizing spray frequency & amplitude, spark takes multiple paths.

Starts sparking more distance from tissue.

Uniform & homogeneous coagulation over large surface area at lower power settings.

Less tissue necrosis & carbonization.

Increases the speed. Reduces the output voltages.

Drastically improves the performance when combined with Argon enhanced ESUs.

PREM – Ultimate safety from burns: Patient Return Electrode Monitoring – PREM is the care &
safety against the return electrode site burns. This ensures burn free electrosurgery using DUAL
AREA Return electrode by continuously monitoring the contact quality with the patient. PREM
system gives an audio-visual alarm and stops the RF output before critical situation arises.

Auto Bipolar : This is the unique feature of which system can deliver automatic bipolar output by
sensing the tissue & stops the power delivery when tissue gets completely coagulated. This
function can work in all three bipolar modes. Auto start delay can be adjusted as explained in
