Technology & set up

Ultravision™ technology is the only one in
its field that uses the proven process of electrostatic precipitation to eliminate surgical smoke.

Technology & set up - Alesi Surgical

This unique mode of action delivers "advanced visualisation": a continuously clear visual field, reduced camera cleaning, and stable pneumoperitoneum.

Ultravision also provides best-in-class control of bioaerosols, being 23-times more effective than smoke evacuators in minimising the release of bioaerosols into the OR during surgery.*

How electrostatic precipitation works in laparoscopic surgery

The Ionwand™ creates negatively charged gas ions in the abdominal cavity, which move towards the “positive” patient tissue.

As the ions move, they collide with water vapour and particulate matter and draw them away from the surgical site. Particles land, and the electrical charge flows back to the generator.

The Ultravision™
& paradigm shift

Standard smoke evacuation systems require a constant flow of CO2 in order to clear the visual field from surgical smoke. This requires excessive use of CO2, with potentially negative effects on the patient.

The electrostatic precipitation method enables a number of benefits including improved visualisation, stable pneumoperitoneum, reduced camera cleaning, reduced exposure to surgical smoke; and the facilitation of low pressure, low flow surgery, which is associated with improved patient outcomes.*

With Ultravision, you're using a fraction of the carbon dioxide. By using a lot less carbon dioxide and operating at lower pressures I think you're being kinder to the tissues and benefitting the patient's recovery. Mr Gourab Misra University Hospitals North Midlands, UK

The beauty of Ultravision is because there is no exchange of CO2, you can actually operate at a much lower pressure of typically 8 to 10 mmHg In other words, 5-7 mmHg less
and use far less CO2 overall.

We have seen that our patient pain scores, pleural effusion numbers, upper respiratory tract infections and therefore length of stay have been significantly reduced when using Ultravision as an integral part of our MIS set-up. Mr John Conneely Mater Misericordiae University Hospital, Dublin

Although CO2 is cheap, if you have the option of using less CO2 – even if it were just 20 litres less for example, then why wouldn't you? Mr Gourab Misra University Hospitals North Midlands, UK

Ultravision™ set up

Use of Ultravision™ (both Ultravision and Ultravision2) is straightforward and involves five simple steps:
1 Establish a patient return path to the system, connect all link cables required
2 Select Ultravision consumable required for your procedure
3 Introduce Ultravision consumable into the ‘surgical field’
4 Ensure the generator is switched on before cutting/coagulation of tissue
5 Switch the generator off at the end of the procedure

The good thing about
Ultravision™ is it is very easy to
set up, you just 'plug and play'
