Chapter 4: Using the Ultravision™ system
This section describes the use of the Ultravision system to clear the visual field of surgical smoke. This step requires the
following consumable items:
• Ultravision catheter, and trocar
• Ionwand
Or
• Ultravision 5mm Trocar
These items are supplied separately.
The use of these accessories is desrcribed separately below:

Inserting the Catheter, trocar and Ionwand

The catheter is inserted using the trocar. The catheter and trocar are supplied assembled and ready for use.
The peritoneal cavity must be insufflated using standard practice before attempting to insert the catheter. Once insufflation
has been achieved:
1. Open the Ionwand sterile packaging.
2. Remove the catheter/trocar assembly and the Ionwand from the packaging.
the trocar/catheter and Ionwand cable and check the integrity of the components.
3. Introduce the catheter by
a. Always insert after the abdomen has been insufflated.
b. Always insert using direct vision to avoid iatrogenic injury to abdominal structures.
4. Remove the trocar from the catheter by holding the catheter and rotating the trocar anti-clockwise and dispose of
safely.
5. Carefully insert the Ionwand down the catheter until it protrudes from the tip and can be visualised internally within
the patient with the laparoscopic camera.
6. Secure the Ionwand in place by holding the catheter and rotating the hub of the Ionwand clockwise until it tight-
ens. Do not overtighten:
7. Adjust the height of the catheter so that the Ionwand is free from contact with patient tissue and surgical instru-
ments.
8. Connect the Ionwand connector to the active socket on the face of the Ultravision generator.
Warning
Single use only – the components have not been designed for re-sterilisation and re-use of this device poses a severe risk of
cross-infection and/or device malfunction.
If the sterile packaging is open or damaged, do not use and discard safely.
If there is evidence of damage to any of the components, do not use and discard safely.
Always insert the catheter or trocar under direct vision once the abdominal cavity has been insufflated. Failure to do so may
result in damage to internal tissue, blood vessels or organs.
Avoid major arteries and veins when inserting the catheter or trocar.
Never attempt to re-insert a partially or fully withdrawn trocar in the abdomen.
Do not switch on the Ultravision generator before inserting the Ionwand into the catheter.
As with electrosurgical instruments, contact between the Ionwand
and uninsulated metallic instruments should be minimised to prevent electrostatic discharge to the operator or patient that
may also transiently interfere with an ECG signal.
Repeated contact of the Ionwand with a video laparoscope may lead to temporary interference with the visual display and/or
damage to the laparoscope.
