Morbus Parkinson is a widespread disease amongst the elderly people. With increasing life expectancy the numbers of patients with Parkinsons disease are rising. Over the last decade, Deep Brain Stimulation (DBS) of certain nuclei within the basal ganglia has been established as an effective treatment for patients with advanced Parkinsons disease (PD) and motor complications not longer adaequatly treated...
Designing a robotic system for surgical procedures is always challenging. Reliability, integration in the operating room and intuitive use even in stressful situations are some major requirements. Our project aims at the improvement of two widespread interventions in minimally invasive surgery (MIS): the endoscopic submucosal dissection (ESD) and the laparoscopic sigmoid resection (LSR). We develop...
The goal in minimally-invasive surgery like NOTES (natural orifice transluminal endoscopic surgery), or single-port surgery, through one artificial incision, is to reduce the operative and post-operative stresses for the patients. Today's challenges for physicians during procedures are the missing mobility of the used flexible instruments inside the human body. Primarily the missing ability to manipulate...
The Stapedotomy is a standard ENT (ear, nose and throat) surgery, where the surgeons use surgical micro hooks and forceps to replace the stapes with a small titanium implant. However, there are some challenges with this procedure. Especially, the non-ergonomic posture of the surgeon increases the hand tremor and leads to an inaccurate positioning of the implant. This may cause hearing loss and the...
In this contribution, an electrically driven walking frame for both passive and active mobility support is presented for the first time. Problems of the musculoskeletal system are an important issue for people dependent on their personal mobility in order to live independently for as long as possible. However, solutions on the market today only offer passive walking frames which may not give enough...
Endoscopy is gradually replacing open surgery in the gastrointestinal tract. Therefore, novel medical devices and instrumentation are required, such as flexible miniaturized mechanisms for tissue joining and manipulation. In this paper, an absorbable implant for the purpose of long-term tissue fixation is presented. An experimental validation of the implant design and functionality is introduced....
