Welds rather than knots – the Fraunhofer IPT has developed a new instrument for keyhole surgery

15.02.2011
Minimally invasive surgery is rapidly becoming the technique for performing increasingly complex keyhole operations. During the MEDTEC trade fair from March 22 to 24 in Stuttgart, the Fraunhofer Institute for Production Technology IPT will be presenting several instruments for this patientfriendly operating technique at stand 6211.

New suture technique for keyhole operations

An instrument recently developed by the Fraunhofer IPT, involving a defined thread tension, can be used to sew up operational wounds within the human body and ultimately accelerate the postoperative healing process.

A laser welds the thread together with a plastic sleeve to form a tear-proof join. This makes it possible to quickly suture the tissue in a confined space with a consistent, reproducible thread tension. The semi-automated process will be tested in cooperation with industrial partners as part of a joint project entitled »Die Naht – SafeSuture« in order to prepare the product for sale.

Glass fiber reinforced plastic guide wires for operations in MRI without ionizing radiation

The traditional forms of x-ray diagnostics and computer tomography often involve high doses of radiation, especially for children, and provide a poorer image of soft tissue than magnetic resonance imaging (MRI). Medics from Kings College in London are now examining a newly developed guide wire made from glass fiber reinforced plastic for use in vascular diagnostics and therapy: in contrast to the common wires made of metal, this fiber reinforced wire does not heat up in a magnetic field and does not interfere with the image. This makes it possible to perform minimally invasive operations on patients in the MRI without causing any ionizing radiation or the need of contrast agents. The Fraunhofer IPT’s guide wire is preparing the way for keyhole operations such as children’s heart surgery – under conditions that are gentler to the patient.

Multi-functional, carbon fiber reinforced plastic puncture needle

The Fraunhofer IPT has also developed a carbon fiber reinforced plastic puncture needle for use in MRI. These needles can, for instance, be used to puncture the spinal cord or for knee and spinal disc operations. They have outstanding mechanical properties and, compared to conventional instruments, are less sensitive to magnetic fields, so they do not interfere with the magnetic resonance image. These needles are already being produced in series and used in human surgery.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
