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...
Bladder cancer constitutes the thirteenth most common cause of cancer death worldwide. Transurethral resection of bladder tumors (TURBT) is the established treatment procedure of non-muscle invasive bladder cancer. However, current techniques for this procedure represent several inadequacies such as inaccurate resection of tumors and high recurrence rates due to the lack of dexterity and limited instrumentation...
Since the minimally invasive surgery has significant benefits for the patient, special equipment and techniques are constantly enhanced in this relatively new surgical field, so that more challenging surgical applications can be achieved. Thereby, the major aim is to enable the surgeon to manipulate instruments inside the human body intuitively, despite restricted access to the operating field and...
Minimally invasive surgery offers the benefits of reduced patient trauma, faster recovery and shorter hospital stay to the patients, what motivates its development towards further less invasive applications. In this work, we present a concept for adapting our 3D-printed overtube manipulator to single incision laparoscopic surgery. Furthermore, we describe the integration of a surgeon supporting ultrasound...
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...
The tympanoplasty-III is a widely used method to heal the conductive hearing loss with passive prostheses. One of the major challenges during this procedure is to determine the correct prosthesis length during the surgery, in order to apply an optimal tension on the tissues. However, a suboptimal tension on the tissues may occur because of a varying ambient pressure and tissue changes after the operation...
Since rapid manufacturing (RM) technologies such as selective laser sintering (SLS) are on the edge to be used for the fabrication of fully functional components or even complete technical devices, we have to adapt the way we think of designing and assembling printable parts. RM makes it possible to realize complex geometrical structures with ease in small amounts at low cost. And it is possible to...
