SmartTrepan: Sensor Guided Trepanation System for safe and efficient craniotomy

02.01.2008
Accidental dural tears in craniotomy significantly increase

infection risk and often complicate the surgical procedure. While some surgical tools attempt to address these problems, they do not completely prevent the tear of the dura mater. Both patients and surgeons require improved technologies and tools for craniotomy and bone surgery.

A novel method and device for on-line detection of bone thickness and navigated trepan position control for effective protection of the dura mater in craniotomies has been developed at the Helmholtz-Institute of the RWTH Aachen University. The bone thickness is determined online at the cutting point and the cutting process can be controlled according to the surgery plan. The Smart Trepan system can be applied to a range of surgical procedures, including craniotomy, or shaping of bones for implants.

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

Im Focus: Hydrogen Bonds Directly Detected for the First Time

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.

Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
