Sensor measurement – Lesion temperature is measured by
thermocouples located within each needle and urethral
temperature is measured by thermocouples located within the
hand piece tip. Impedance is measured from the generator,
through the hand piece and targeted tissue, and back to the
generator via the return electrode. The sensor measurements are
displayed by the RF generator display screen.
The high-impact plastic generator case has a convenient carrying
handle and a flip-open display screen. An easy-to-use latch
mechanism secures and releases the flip-open display screen.
The display screen provides clinicians with real-time treatment
information in graphical and digital formats. Message fields on the
display screen also provide critical information during the
treatment procedure.
See Table 6-1 "Model 8930 Radio Frequency Generator
Specifications" on page 94 for limitations of proper device
operation.
The user interface includes a touch-screen that responds to
gloved and ungloved touch. When the clinician touches a
control-button icon on the screen, the system performs the
function selected if no errors exist.
The user interface also provides unique audible tones to
automatically notify the clinician of the treatment status or alert
condition.
Detailed data for all lesions created during each patient session
are collected and stored for review. The measurements for power,
impedance, and temperature (for the left and right needles and for
the urethra) are logged at intervals of 500ms and stored in an
array during each lesion.
The information for up to 64 patient sessions is stored in a rolling
buffer. After 64 sessions are saved, the oldest session record will
be deleted as new sessions are recorded. The saved data is not
affected by turning the generator off or by any other loss of
generator power.
