General Information
Indications
The Ultravision system is indicated for the clearance of smoke and other particulate matter that is created during
laparoscopic surgery.
Contraindications
The Ultravision system is an electrical energy-based system that must not be used on patients tted with a pacemaker or
implantable cardioverter debrillator (ICD).
Device Description
The Ultravision device is intended to remove surgical smoke from the visual eld during laparoscopic surgical procedures
by means of electrostatic precipitation. Surgical smoke refers to the suspended aqueous and particulate matter that is
generated as a by-product of the combustion and other processes that are associated with the use of energy-based surgical
instruments.
The components of the Ultravision system are described in Table 1. This service manual only concerns the Ultravision
generator and battery recharger.
Component Description Purpose
Standalone battery operated generator Electrostatic energy source.
Battery recharging station Recharging of the reusable battery.
Ionwand Delivery of the energy from the generator that charges the
surgical smoke particles in the abdominal cavity.
Catheter Holds Ionwand in place during surgery.
Trocar Introduction of the catheter into the abdominal cavity.
Patient return adaptor Provides common return path with electrosurgical generator,
allowing use of a shared patient return electrode.
Table 1: Components of the Ultravision system
Maintenance Checks
The Ultravision system should be inspected at least once every year, regardless of use. This inspection should include
checks for:
• Any visible damage to the generator and recharging station.
• Visible damage to the battery recharging station power cable and plug.
• Visible damage to the patient return adaptor cable or connectors. Proper mating between the patient return
adaptors and the Ultravision generator and electrosurgical generator. Functionality can be assessed by
connecting a patient return electrode to the Ultravision Generator return socket and to an ESU return socket via
a patient return adaptor cable and an Ionwand to the Ultravision generator active socket. Then switch on the
Ultravision generator and touch the Ionwand brush to the patient return electrode. The Ultravision
generator proximity alarm (see Table 3) should sound and the ESU should indicate a correctly-congured patient
return electrode.
• Visible damage to the batteries: Remaining capacity can be assessed by rst charging the batteries overnight
and then observing whether they can sustain at least 8 hours’ Ultravision generator operation. If not, they should
be replaced.
Service inspections for the Ultravision generator are described on page 9 and the results of these should be recorded in the
Ultravision Inspection Log on page 14.
A service inspection routine for the battery recharging station is described on page 12 with the corresponding Inspection Log
on page 15 of this service manual.

1 – Volume control
The Ultravision generator has four audible indicators that accompany the visual indicators:
Indicator
Scenario
Audible Indicator Visual indicator
Tone Description Frequency
Low battery High (1047 Hz) A single 1 second tone 2 seconds Low battery LED
Proximity Medium (523.3 Hz) A single 300 millisecond tone 6 seconds Proximity LEDs
Generator fault Low (261.6 Hz) A single 1 second tone 2 seconds Fault (!) LED
Power ON reminder Low (261.6 Hz) A single 1 second tone 15 minutes None
Table 3: Ultravision audible indicators

The generator sounds the three different tones in sequence when switched on. The volume of these indicators may be
adjusted by twisting the volume control on the rear of the generator. The volume is increased by turning the volume control
clockwise, and reduced by turning anti-clockwise.

Functional Testing
To perform a complete service check of the Ultravision generator you will need the following equipment:
• A fully-charged Ultravision battery
• A digital voltmeter with leads and crocodile clips
• A sheet of metal foil approximately 0.5m x 0.5m in size
• An Ultravision Output Verication Unit (available from your local Alesi distributor)
Perform the following tests in sequence. If any of the tests do not lead to the required result, then consult the next section
“Repair actions”.
ITEM FUNCTION TEST REQUIRED RESULT
1 Enclosure
integrity
Inspect outer casework of generator for any
cracks, holes or damage.
No visible damage to casework. Outer
plastic enclosure not compromised.
2Check all 5 rubber feet tted to underside of
generator.
All ve rubber feet securely tted to base of
generator.
3Inspect Calibration label at rear of generator. Calibration label intact across split between
base and lid of generator.
4 Battery
mechanism
Push charged battery into Ultravision battery
bay ensuring that the battery is the correct
way up in accordance with the battery label.
Battery bay should click to engage and hold
battery in place.
5 Interface controls Power on generator using On/ Off switch. On/ Off switch clicks into ON position.
6Simultaneously listen to sound produced by
generator on start-up. If necessary, cycle the
On/Off switch until the start-up sound has
been assessed.
Generator produces three rising tones.
7Simultaneously observe fault light. If
necessary, cycle the On/Off switch until the
fault light state has been assessed.
Must illuminate red transiently.
8Inspect power LED adjacent to On/ Off
switch.
Power LED should be illuminated green.
9Inspect battery meter LED. Battery meter LED should be illuminated
green or amber. Red indicates that the
battery being used does not have sufcient
power and should be replaced with a fully-
charged battery before repeating this test
and continuing with steps below.
10 I/O sockets Connect output verication unit to the active
(Ionwand) and return sockets on front on
generator.
Conrm that a good connection is made –
no loose plugs.
11 Output current
calibration
With the output verication unit jumper lead
at the front of the device disconnected, listen
to the sound produced by the generator.
The generator does not sound the proximity
alarm.
12 Proximity alarm Connect output verication unit jumper cable. The generator now sounds the proximity
alarm (repeating pattern of 300ms tone
followed by 6 second pause).
13 Volume control While the proximity alarm is still sounding,
turn the volume control at the rear of the
generator.
Conrm that the volume control rotates and
causes the output volume of the generator
to increase and decrease.
14 Battery release
mechanism
Switch off the generator by means of the
On/Off switch and push the tab next to the
battery slot on the right hand side of the
generator
Battery should eject from generator.
15 END OF TEST Disconnect the output verication unit from
the generator sockets.
If all of the above test steps have produced
the required result then the generator may
be returned to service.

Enclosure insulation
In order to conrm ongoing electromagnetic compliance (IEC 60601-1-2), the integrity of the enclosure insulation can be
assessed by placing the generator on a sheet of metal foil and measuring the current between the foil and ground when the
generator is switched on using a digital multimeter. When carrying out this test the operator should stand at least two feet
away from the generator to ensure a stable reading. The leakage current reading should not exceed 0.1uA.
Repair actions
The Ultravision system is subject to precise calibration as part of the manufacturing process. All servicing and repairs must
be conducted by the manufacturer so as not to void any warranty or potentially compromise the safety and/or performance
of the device. Do not attempt to open or repair the device.
If any of the inspection methods listed above suggest that the Ultravision or one of its reusable accessories are damaged,
take the generator and/or recharger out of circulation immediately and contact your local distributor to arrange repairs.
In some instances it may be possible to send a replacement part but complex repairs will necessitate the unit being returned
to the manufacturer.
Troubleshooting
Situation Possible cause(s) Recommended action
Generator does not power up
when switched on
No battery power remaining. Replace with fully charged battery.
Faulty generator. Contact manufacturer or local distributor.
Fully charged battery does
not support generator
operation for expected
duration.
Battery at end of life through
use or damage.
Replace with new battery.
