Use Of The Catheter, Trocar And Ionwand During Surgery; End Of Surgery - alesi ULTRAVISION Manual De Usuario

Caution
The sterile components have been design specifically for use with this system. Only use items supplied by Alesi Surgical.
Advice
Insert the catheter in a position where it will not impair the surgical procedure and where it is least likely to come in to contact
with other surgical instruments. Smoke clearing is most efficient when placed between the laparoscope and the site of sur-
gery.
Ensure that the tip of the catheter is at least 25mm (1") from patient tissue to reduce the risk of accidentally activating the
proximity indicator.
Cover the lumen of the catheter with a finger prior to inserting Ionwand to minimise loss of pneumoperitoneum. Ensure that
the Ionwand brush is straight before insertion into the catheter.

Use of the Catheter, Trocar and Ionwand during surgery

Before starting to cut or coagulate tissue and creating smoke:
1. Ensure that the Ionwand is free of surgical debris and not touching patient tissue or a surgical instrument.
2. Switch on the Ultravision generator. If the battery status light indicator is flashing red and the battery alarm is
sounding, replace the battery with a fully charged unit.
3. Perform surgical procedure.
4. In the event that the proximity indicator sounds when the Ionwand™ is not touching patient tissue or a surgical
instrument, perform the following steps:
5. Switch off the Ultravision generator.
6. Remove the Ionwand™ from the catheter by holding the catheter and twisting the Ionwand anti-clockwise, ensur-
ing the catheter is not displaced.
7. Clean the Ionwand™ and brush filaments by enclosing it within a sterile swab moistened with sterile saline and
gently wiping it, moving the swab from the insulated portion of the Ionwand towards the metal brush. Repeat until
all contamination has been removed and the brush is clean.
8. Re-introduce the Ionwand into the catheter and secure by holding the catheter and twisting the Ionwand in a
clockwise direction.
9. Switch on the Ultravision generator and confirm that the indicator condition has resolved and that smoke clearing
has been resumed.
10. If the alarm continues to sound, remove and replace the Ionwand.
Warning
To maximise patient safety, contact between the Ionwand and metallic instruments should be minimised. Otherwise, the
metal instrument may be charged resulting in an electrostatic discharge to the patient or operator. This may be sufficient to
cause atrial fibrillation depending upon proximity to the thoracic cavity.
Accidental activation of a monopolar electrode in contact with the Ionwand should be avoided. Provided the Ionwand cable is
connected to the Ultravision generator there is no risk of accidental burn or shock to the patient or surgical staff, but there is
no proven redundancy in this protective insulation.
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.
If the Ultravision catheter becomes disengaged from its position during use replace with a new device.
The system should not be used unless the user has been trained in its use.

End of surgery

When the surgical procedure has been completed or there is no longer any requirement for the Ultravision to be active:
1. Turn off the Ultravision generator.
2. Disconnect the Ionwand cable from the generator.
3. Carefully remove the Ionwand from the catheter
