Covidien/Valleylab Force Ez Electrosurgical Generator

Surgeons can benefit from instant response technology, which enhances their performance and reduces the risk of tissue damage and neuromuscular stimulation. It also eliminates the need to manually increase the power settings. The Force EZ generator, equipped with this technology, automatically adjusts itself to adapt to tissue changes during surgery. This ensures a constant power delivery and minimizes any resistance encountered.

One of the advantages of using instant response technology is the significant reduction in capacitive coupling, which can be up to 30-50%. This reduction is achieved by controlling the RMS voltage and high-frequency harmonics. By lowering the voltage, the technology minimizes neuromuscular stimulation and ensures precise energy delivery, thereby minimizing any collateral damage.

If you are in search of more Valleylab electrosurgical units, you might be interested in the Covidien Valleylab Force FX. This device also incorporates instant response technology, featuring an advanced feedback system. This system can detect tissue changes an impressive 200 times per second, allowing the generator to adjust voltage and current accordingly. This ensures that the power output remains appropriate for the specific surgical requirements.

What sets instant response generators apart is their high power efficiency rating (PER), which is made possible by their smart generator technology. PER indicates how accurately a generator can deliver the selected power across a wide variety of tissue types. With a remarkable PER of 97, the Force EZ generator consistently achieves the desired surgical effect.

In summary, instant response technology revolutionizes the field of surgery by providing surgeons with improved performance and reducing the risk of tissue damage. The Force EZ generator, along with other Valleylab electrosurgical units like the Covidien Valleylab Force FX, exemplifies this technology with their advanced feedback systems and high power efficiency ratings.

FEATURES:

• Instant Response technology ensures that the power delivered remains virtually constant, regardless of the tissue type
• Improved performance at lower power settings minimizes the risk of tissue damage and neuromuscular stimulation
• Three internal microcontrollers reduce system reaction time and increase the system's processing speed
• Easy to use, cost-effective system when performance is required and the price is of equal concern
• Two cut modes, both controlled by Instant Response technology, offer surgeons a variety of choices:
• Pure Cut for a clean, precise cut
• Blend for cutting with hemostatsis
• Two primary coag modes:
• Low for lower voltage contact coagulation suitable in laparoscopic and delicate tissue work
• High for efficient non-contact coagulation in most applications
