Noyt, an orthopedic specialist, recreates custom corsets using 3D scanning technology.

NEUT, a century-old company specializing in orthopedics, uses 3D technology in the context of its custom-made medical corsets. This is a real technological breakthrough with many benefits for patients.

Neut, a French company based in Saint-André-lès-Verges (10), Paris and Versailles and operating in the Île-de-France and Champagne, produces with know-how a wide range of individual appliances, especially for patients who need the manufacture of corsets (postoperative, medical, patches, etc.) for their removal.

A manufacturer of high-performance, high-quality orthopedic equipment and constantly on the lookout for new technologies and innovative products to meet the needs of patients and professionals, the Neut teams have been captivated by the use of 3D technology in the context of orthopedic equipment manufacturing. .

Purpose: to offer modern prostheses and orthoses in terms of manufacturing technologies, materials and equipment used, both for serial and for individual production.

Improve patient comfort during bracket measurement

Prior to the use of Artec 3D scanners, the corset manufacturing process systematically consisted of making plaster casts directly on the patient’s body. The bust is closed, then cast and molded by hand. This physical and unpleasant operation, which took a long time and could be felt as depressing, even traumatic, especially for the youngest patients; the step of cutting out the shape with a vibrating saw is also an inconvenient and impressive step, especially for children (and their parents).

This corset-making operation, which lasted at least three days, was also very messy for the patient. This had to take place in a plaster room and required a lot of mold work, sometimes very heavy. While sculpting and fixing were previously done by hand, Noyt’s orthopedists used 3D scanning technology to accurately recreate the corset models down to the smallest detail.

From now on, technology makes it possible to care for patients who cannot stand up, limiting manipulation and in complete safety. Scanning makes it possible to digitize relevant body parts while lying in bed without the need to move, which reduces their discomfort, the stress caused by the operation, and the necessary physical effort. Digitization with millimeter accuracy is much faster and more pleasant for both the patient and the applicator.

Mobile 3D technology, more accurate and faster

In order to produce scans tailored to his needs, respecting his specifications and reproducing every detail of the patient’s body, Noyt chose 5 Artec Eva Lite scanners.

In addition to being easy to handle, the Eva Lite 3D Scanner features pulsed light technology that does not interfere with hospital environments or equipment rooms, which was important given Noyt’s line of work, which routinely scans hospitals. after the patients have been operated on.

The high accuracy, down to the millimeter, of this scanner is also a big advantage over other technologies used, such as mobile applications on tablets, which are less accurate and require a lot of manual corrections. », explains Alexander Neut, Neut’s CEO and Orthopedist. ” Even if the patient moves during the scanning steps, the Artec Eva Lite scanner automatically corrects inaccuracies. »

The mobility of the Artec Eva Lite was also a strong point in choosing Neut. The ability to transport your scanner is an important advantage for applicators, which can therefore scan anywhere (hospitals, medical offices, rehabilitation centers, etc.).

3D technology will revolutionize orthopedics

In the second step, the corset models are optimized on the computer using the Artec Studio data processing program, which allows users to create, edit and process 3D data regardless of the size or resolution of the object.

Each scan then requires several minutes of computer processing. After digitization, the scans are processed and exported to special orthopedic software.

The software allows you to make corrections and adjustments in accordance with pathologies. The file is then sent to a digital milling machine, which mills a positive molding from a block of polyurethane (bust 1 kg).

For all scanned patients, the software also allows archiving to update the digital history of certain devices and thus be able to reuse digitized impressions from year to year in the event of an update, thus avoiding the bulky storage of plaster positives that can reach 50 kg at Neut .

We have been able to pass the technological milestone thanks to the research and development provided by Artec 3D. Now we can virtually perform hundreds of manual operations and transcribe them into a digital version. It also turned out that many employees, especially the youngest of us, are eager for these new technologies, which are revolutionizing the daily lives of patients, orthopedists and production shops. We are very pleased with the cooperation with Artec 3D through our partner. CAD Vision who has been helping us and giving us the best advice for many years. »

In the future, we plan to expand the use of 3D technologies for the design of patterns for the manufacture of orthopedic shoes, as well as for the upholstery of medical devices, thanks to the ability to convert a 3D file to 2D.

Our age-old craftsmanship has been able to evolve and take a technological turn to discover new ways to do, see, design. ”, concludes Alexander Noit.
