Monopolar cutting electrosurgical unit Cresta IsT

bipolar cuttingRF

Overview
The Cresta IsT is an advanced RF electrosurgical generator platform designed for precision electrosurgery. It uses a split-port configuration for dedicated Bipolar and Vessel Sealer outputs and supports monopolar, bipolar and vessel sealing modes. Integrated technologies (ContactIQ, SureBind, SafeZ, TURiCUT) provide real-time tissue sensing, adaptive energy delivery and system diagnostics to support consistent clinical results.

Key highlights

• Vessel sealing capability up to 7 mm
• Underwater monopolar cutting capability
• Return Electrode Monitoring (REM)
• RF Cut and multiple Cut/Coag modes
• Consistent tissue effect with real-time sensing
• 7-inch intuitive touchscreen control
• High-performance ARM32 microcontroller (sampling rate >10,000/sec)
• Split-port outputs for Bipolar and Vessel Sealer
• Program manager and self-diagnosis functions
• Visual and audible warnings

Notes

• The ratings above are maximum ratings.
• All output power values are available within ±20%; peak voltage and crest factors vary accordingly.
• Power can be reduced intraoperatively by selecting appropriate settings.
• Use the lowest power setting that achieves the required surgical effect.
• Vessel Sealer power is modulated during sealing cycles.
