With the patented method of Navigated Control active surgical instruments can be stopped before they endanger delicate and sensitive tissue such as nerves and vessels. To this end, a stereo camera tracks the positions of instrument and patient, a computer then measures the distance to the patient structure and calculates the allowed output power for the instrument. This clinically approved principle...
The use of flexure hinges offers significant benefits compared to conventional revolute joints, such as the use for compact monolithic designs of flexural structures, no friction losses and reduced assembly and manufacturing costs. The combination of this design concept with additive manufacturing (AM) techniques provides huge potential for kinematics design, because of the ability to manufacture...
Surgical navigation systems based on optical tracking technology all suffer from the requirement for an unobstructed line-of-sight. The optical path between stereo camera and tracked objects has to be kept free or the navigation is suspended. In this article, we present a new module that combines the information of two tracking cameras simultaneously, to view the surgical site from two different angles...
During the implantation of Deep Brain Stimulation Electrodes for the treatment of Parkinson's disease the operating team of neurosurgeons and neurologists evaluates the symptom improvement at multiple electrode positions in order to decide where a permanent electrode can achieve the best benefits. This evaluation is done and documented manually. In this project a mechatronic device has been developed...
Through advances in technology and processing power more and more functionality can be integrated into medical devices and will find its way into the operating room (OR). New complex assistance systems can support the surgeon in performing his tasks and help to obtain better results. With an increasing number of computer assisted devices, the demand for data exchange between them is growing. If these...
Among numerous medical devices that generate noise, music is gaining increasing importance in modern operating rooms. Many surgeons perceive music as concentration enhancing during surgery. In safety critical situations instead, e.g. when a medical device emits an alarm, the additional noise exposure induced by music is considered distracting. In this article we present a novel, modular device that...
