Getinge: the team behind a new OR light feature

With the passion for life and aided by sophisticated new technology, Getinge’s OR lighting team in France has successfully solved one of the major challenges for surgeons working with NIR fluorescence imaging.

“NIR imaging allows surgeons to see what is invisible to the naked eye. The technology is used to distinguish structures that need to be removed, such as sentinel lymph nodes and malignant cells, nerves, blood vessels and other structures that should be avoided, ”says Robin Jousse, R&D director, Surgical Lights at Getinge.

He continues, “The downside is that traditional OR lights interfere with NIR imaging. Until now, there has been no OR light on the market that can stay on when the surgeon is assisted by a NIR camera.

Working closely with surgeons in France and Argentina, the project team focused on optimizing the three-filter configuration of Maquet Volista to work in harmony with the NIR imaging device.

Minh Hong Vu Thi, optical engineer at Getinge, explains:

“We cooperated with our filter coating supplier with the aim of maintaining the good characteristics of the visible light spectrum, while suppressing the signal in the NIR range. We wanted to eliminate the parts of the surgical light that disturb the fluorescence signal. of the NIR device. “

During the development process, Volista VisioNIR has been evaluated by physicians under real surgical conditions.

“It was vital for us to have a direct link between our R&D team and the experts working with NIR imaging. This was useful in knowing the different surgical protocols and in understanding the constraints of the operating room team. After several design loops, followed by feedback, the surgeons were really satisfied with the result, ”explains Robin Jousse.

The Maquet Volista VisioNIR and NIR guided surgery cameras can now be used simultaneously in the operating room during the entire procedure. Getinge’s solution maintains the standard for operative lighting, with good color rendering and no compromises in dilution or gradation of shadows.

“Without having to turn operating room lights on and off, the surgical team benefits from improved hand-eye coordination and uninterrupted workflow. This allows you to constantly focus on the patient, ”explains Robin.

Asked about a key moment in the research process, Robin Jousse and Minh Hong Vu Thi both mentioned the ability to locate NIR irradiance in OR light. It was crucial in determining what to eliminate.

“Detecting a very weak NIR signal when you have strong visible light is particularly difficult. We needed a specific NIR spectrometer to achieve enough noise reduction to measure the NIR signal accurately,” says Minh Hong.

“With this device we have found the explanation why certain combinations of filters did not give the desired result. It was a decisive step on the way to the creation of this powerful feature, which we believe will have a big impact on surgery for years to come, ”concludes Robin.
