Changing the Energy Delivery Setting
The green bars on the LigaSure vessel fusion display panel represent different
levels of desiccation. Two green bars are the default setting for all LigaSure tissue
fusion instruments. This setting allows the energy to precisely affect the target
tissue, resulting in permanent tissue fusion with minimal thermal spread to the
surrounding tissues. Occasionally the surgeon may encounter tissue or vessels that
are fused more effectively with a one or three bar fusion cycle. By selecting one
bar, the surgeon can expect a more gentle and typically longer fusion cycle, which
can be potentially more effective in thinner tissue bundles and smaller, isolated
vessels. By selecting three bars, the surgeon can expect a longer fusion cycle,
which can be potentially more effective in thicker tissue bundles.
1. You may adjust the instrument setting by touching one of the three setting
buttons on the respective LigaSure 1 or LigaSure 2 control panel. The button
touched along with the buttons to the left of it become green, and the standby
button turns grey.
2. As a safety feature, you may set the ForceTriad energy platform on standby
until you are ready for surgery by pressing the standby button.
When on standby, no energy will be delivered through the LigaSure
instrument. If you attempt to activate a LigaSure instrument, a single, short
tone will sound.
3. To bring the energy platform out of standby, press a desired bar setting.
Previous bar settings will not be stored in standby.
Activating the LigaSure Instrument
1. Activate the LigaSure instrument either by pressing and holding the activation
button on the instrument or by stepping on and holding the footswitch pedal.
During instrument activation, the status bar in the corresponding LigaSure
control panel illuminates blue, and an activation tone sounds for the duration
of energy delivery.
2. When the end tone is heard, you may release the activation button or
footswitch pedal. In the case of an alert condition, refer to the following
section.
Warning
Confirm proper power or intensity settings before proceeding with surgery.
Notice
The one and three bar seal cycles may result in tissue sticking due to longer
dessication periods.
