BACKGROUND In literature and scientific societies no binding methodical-didactic recommendations or guidelines exist in order to design surgical training courses. The educating institutions plan, organise and evaluate the educational program on their own initiative. MATERIAL AND METHODS Through a research project surgical training courses were(More)
To reduce the risk of application error, the federal legislator has demanded a development process which is oriented towards usability (DIN EN 62366). Therefore, the research question concerns the application of this standard by medical device manufacturers. Questionnaires were filled out by five trained interviewers in fully standardized face-to-face(More)
INTRODUCTION Engineering a medical technology is a complex process, therefore it is important to include experts from different scientific fields. This is particularly true for the development of surgical technology, where the relevant scientific fields are surgery (medicine) and engineering (electrical engineering, mechanical engineering, computer science,(More)
Automation ist das Resultat einer Übertragung von einzelnen Funktionen oder ganzen Tätigkeiten vom Menschen auf die Maschine (Hauß & Timpe, 2000). Auch im modernen Operationssaal finden sich Beispiele für Automation. Angesichts des hohen Sicherheitsbedarfs und möglicher irreversibler Folgen ist es notwendig, Automationsfolgen auch im Bereich der Chirurgie(More)
An initial research indicated that realistic haptic simulators with an adapted training concept are needed to enhance the training for spinal surgery. A cognitive task analysis (CTA) was performed to define a realistic and helpful scenario-based simulation. Based on the results a simulator for lumbar discectomy was developed. Additionally, a realistic(More)
The aim of this study was to develop an easy-to-induce and reproducible model of gastric submucosal tumor in swine to compare minilaparoscopy (ML) with single-incision (SI) intragastric surgery. Twelve healthy female pigs (weight 30.94 ± 2.49 kg) underwent a transparietal injection of sterile alginate at the level of Z-line (n = 6) and at the pre-pyloric(More)
The objective of this study is to assess the surgeons’ performance and ergonomics during the use of a robotic-driven needle holder in laparoscopic suturing tasks. Six right-handed laparoscopic surgeons with different levels of experience took part in this study. Participants performed a set of three different intracorporeal suturing tasks organized in ten(More)
A safe application of modern surgical technology and computer-assisted surgery devices is based on an operation by adequately trained surgeons who are familiar with the benefits and limitations of the devices. We analyzed the in-depth interviews with seven Spanish and 10 German surgeons. Together with other studies, this analysis highlights the need for(More)
