The VASOVIEW 7 Harvesting Cannula is used for branch
cauterization and transection. The design of the instrument
aims the endoscope, BiSECTOR™ Bipolar Ligating Forceps,
and C-Ring in one direction, allowing easy vein protection and
branch transection. By design, the BiSECTOR tool position
will always be opposite the C-Ring “struts.” (Figure 20)
After dissection of the vein, withdraw the endoscope from
the tunnel leaving the BTT in place. Remove the Dissection
Tip by unthreading it off the endoscope. Remove the Endo-
scope Seal from the BTT and replace it with the Harvesting
Cannula Seal.
Apply anti-fog solution to the distal tip of the endoscope if
desired. Insert the endoscope into the bell handle of the
VASOVIEW 7 Harvesting Cannula. The endoscope is
secured with an audible “click,” locking it into place.
(Figure 21)
Attach the Bipolar Cord to the VASOVIEW Harvesting
Cannula. Ensure that the Bipolar Cord is connected to the
bipolar generator. Place the bipolar foot pedal by the
harvester.
Set the bipolar generator wattage according to
recommendations in the VASOVIEW 7 xB Endoscopic
Vessel Harvesting System Instructions For Use (settings
differ by type of generator).
Pre-test the BiSECTOR tool to verify complete electrical
activity and generator setting. (Complete instructions are
noted in the VASOVIEW 7 xB Endoscopic Vessel Harvesting
System Instructions For Use.)
Ensure that the BiSECTOR tool and C-Ring are fully
retracted into the Harvesting Cannula, then insert the
Harvesting Cannula through the BTT. Advance the
Harvesting Cannula to the most distal portion of the tunnel,
maintaining a central position to avoid injury to the main
vessel and endoscope sliming. Always maintain correct
orientation of the camera.
