1-2 SurgiStat II Service Manual
Functional Description
The SurgiStat II is a multipurpose electrosurgical generator for use in physician’s
offices and surgi-centers. It provides unsurpassed performance, flexibility,
reliability, and user convenience in one compact package.
The SurgiStat II generator includes digital technology. This new technology is
evident in the self-checking circuitry and error code readouts. The unit offers
monopolar and bipolar electrosurgical operations.
The following are SurgiStat II key advantages and benefits.
Power Capabilities Up to 120 watts (W) of Pure Cut
@ 500 ohms (
Ω
).
Up to 90 W of Blend @ 800
Ω
.
Up to 80 W of Desiccation @ 1000
Ω
.
Up to 40 W of Fulguration @ 1000
Ω
.
Up to 30 W of Bipolar @ 200
Ω
.
Two Levels of Coagulation:
Desiccation and Fulguration Desiccation provides precise control
of bleeding in localized areas.
Fulguration provides greater control of
bleeding in highly vascular tissue over
broader tissue surface areas.
Return Electrode Monitoring
System The unit incorporates a return
electrode contact quality monitoring
system (RECQMS). This system
determines the type of patient return
electrode attached (single-plate or
split-plate).
It also continuously monitors the
contact impedance between the
patient and the split-plate patient
return electode.
Contact impedance is only monitored
when approved split-plate patient
return electrodes are used.
Memory The generator automatically powers
up to the last modes selected, and
previously set power settings.
Isolated (Floating) Radio
Frequency (RF) Output This minimizes the potential of
alternate site burns.
