Polymer composite tubing for endoscopic and laparoscopic applications

Polygon Composites Technology specializes in the design and manufacture of medical and orthopaedic polymer composite tubes
.
The company exhibited PolyMed composite pipes at Compamed
.

Polymeric composite tubes are used on medical devices that require endoscopic and laparoscopic applications
.
It is commonly placed on monopolar and bipolar electrosurgical instruments, surgical ablation tools, endoscopic/laparoscopic instruments, and robotic surgical techniques
.

Polygon's composite pipes are not only lightweight and have strong physical properties, as well as radiation and dielectric resistance, thin walls, rigidity, and stability even when sterilized using EtO, gamma, and other methods, in compliance with ISO-10993 standards

Laminated Silicone for Sensors and Actuators

Wacker Chemie presents NEXIPAL® at Compamed
.

NEXIPAL® is a new type of electroactive laminated silicone
.
Laminated with multiple layers of ultra-thin silicone precision films coated with conductive materials, the product can be used as a motion actuator when a voltage is applied
.

This electroactive laminated silicone allows the display to vibrate or emit a tactile signal that can be identified and manipulated by touch, without the need for eyes
.

In addition, NEXIPAL® laminated silicone can be used as a sensor for measuring mechanical deformation
.
The product has strong wear resistance, small size and low energy consumption, making it an ideal material for innovative applications
.
For example, after using NEXIPAL®, the touch screen can simulate a keyboard with the help of vibration and tactile signals, which can be recognized and operated by touch without eyes, which is especially attractive for automotive applications

PEEK 3D printed surgical implants

Evonik is presenting PEEK in 3D printing at Compamed
.
For patients and physicians, 3D printed PEEK implants are undoubtedly a revolutionary product compared to conventional metal solutions on the current orthopaedic implant market
.
3D printing makes customization possible
.
For example, through 3D printing technology, a bone plate can be made that precisely fits the patient's skull, reducing the risk of additional surgery caused by adjusting the size, shape or position of the implant
.

On the other hand, PEEK is less thermally conductive than metal
.
Therefore, exposure to high and low temperature environments can effectively reduce the risk of over- or under-temperature of the implant in the patient's body
.
In addition, PEEK material has high biocompatibility and is harmless to living tissue, and patients can be examined by CT and MRI after surgery
.

In September this year, Evonik invested in a start-up company in China that produces neurosurgery and spinal surgery implants by 3D printing, Shanghai-based Maiditu Medical Technology Co.
,
Ltd.
The company's technology enables faster patient recovery, fewer post-operative exams, and lower surgical risks
.
Evonik led the round, which totals several million euros
.

"This is Evonik's first direct investment in China, and it is also the first direct investment made using Evonik's second phase of the venture capital fund launched this year," said Bernhard Mohr, head of Evonik Venture Capital.
The partnership with Tutu is a great example of how venture capital can help Evonik acquire disruptive technologies
.
”

Meditour has developed a set of hardware and software systems that can read and process images directly from conventional magnetic resonance imaging (MRI) or computed tomography (CT) equipment
.
The system then generates an easy-to-print 3D model and sends it to the printer
.
Finally, Evonik's high-performance polymer polyetheretherketone (PEEK) is used as the raw material to make the implant through 3D printing technology
