Performance data

Performance data - Alesi Surgical

Ultravision™ has undergone a variety of rigorous independent tests, achieving outstanding results.

Ultravision consistently meets its primary objective of providing a clear visual field. Unlike some of its competitors, Ultravision’s technology ensures other ‘knock on’ effects are avoided, allowing it to achieve exceptional all-round results.

The below data highlights the ‘game-changing’ results achieved by Ultravision when measuring visualisation, surgical smoke management, CO2 management, and the procedural efficiencies achieved.

Visualisation performance data

Ultravision consistently delivers advanced visualisation,
optimising procedural performance

Performance data - Alesi Surgical
Study

Visual field comparison
performed by Dr. Jin S. Yoo at
the Duke Regional Hospital, US

Results

1) Rapidly supresses surgical smoke which provides continuously clear visualisation
2) Ultravision does not rely on diluting the smoke filled abdomen with new CO2
3) Stable pneumoperitoneum, due to no gas exchange, enables low pressure surgery

Advanced visualisation study

Study

Ansell et al (2014)
Evaluate Ultravision's performance during laparoscopic cholecystectomy

Results

Test concluded that Ultravision improves
visibility during laparoscopic surgery and
significantly reduces procedural delays
for smoke clearing and camera cleaning.

The surgeon’s view

When we’re doing laparoscopic surgery visualisation is just about everything.

We need to be able see very clearly what we are doing and anatomically what we are trying to accomplish.

Smoke management performance data

Ultravision proves to be more efficient in controlling bioaerosols than traditional smoke evacuation systems

Study

Ultravision versus Continuous Smoke Evacuation Systems

Smoke Management Performance Data - Alesi Surgical

1) Continuous Smoke Evacuation experiences additional escape of smoke particulates through leaks in trocars and instruments exchanges.

2) Ultravision suppresses smoke and bioaerosols at the point of creation which reduces the likelihood of release in the operating room.

Result

Bioaerosol escape from the abdomen into the Operating Room is significantly reduced with Ultravision.

A remarkable 23x reduction in bioaerosols is achieved.

Study

Measuring speed & effectiveness.
Ultravision v filter-based smoke evacuation system

Result

Ultravision minimises surgical smoke, providing two levels of risk reduction;

Two levels of risk reduction

1. Particle suppression at the point of creation

2. More rapid elimination of smoke compared to smoke evacuators

After 60 seconds Ultravision removes 99.9% of particles from the atmosphere, versus 30.2% with a smoke evacuator.

Study

Removal efficiency test for sub-viral particulates

Result

1. Suppresses 99% of particulates down to 0.007um (7nm, sub-viral sized) from aerosolisation. Ability to contain sub-viral sized particles.

2. The only product independently verified to be effective at sub-viral particle sizes.

CO2 management performance data

Ultravision’s unique system facilitates low pressure, low flow surgery and reduces CO2 usage

Study

A test to explore the use of Ultravision in facilitating low pressure surgery in total laparoscopic hysterectomy (TLH) and myomectomy.

Results

Ultravision enhances low pressure laparoscopic hysterectomy and myomectomy. This was achieved by minimizing interruptions to surgery and exchange of CO2; providing a clear visual field throughout the procedure; and eliminating surgical smoke at the site of origin.

Study

Dr. Jin S. Yoo demonstrates the benefits of Ultravision
when performing Bariatric surgery Roux-en-Y.

Results

A clear field of view is maintained
alongside a stable pneumoperitoneum.

Study

Dr Yera and Mr Misra share their experience of
using Ultravision in laparoscopic surgery.

Results

CO2 pressure is maintained due to low exchange of CO2.
Low volume CO2 used, resulting in a high level of surgeon satisfaction in being able to operate at the lowest safe pressure whilst using minimal CO2, in line with clinical guidelines.

Improving OR efficiency

Ultravision enables a more efficient OR through time savings and reduced CO2 usage.

Study*

Oxford University Hospitals measured the procedural efficiencies achieved across four laparoscopic specialties.

The financial impact was calculated based upon any efficiency gain.

*Source: Efficiency and Innovation presentation given at the HCSA conference, 2017.

Results

Efficiency improvements in all specialties:

- Gynae - 20 minutes per procedure
- Upper GI - 14 minutes per procedure
- Colorectal - 10 minutes per procedure
- Urology - 9 minutes per procedure
- Potential to add 1 additional procedure per list
   plus reduced risk of overrun

An additional £1.7m revenue per year was estimated, based upon the ability to schedule additional procedures.

Results

- 8 minutes per case saved
- Zero pauses in 77% of procedures
- No camera cleaning required in 95% of cases
