Chair of Sensor Based Robotic Systems and Intelligent Assistance Systems

The primary mission of this chair is teaching and research in the fields of design, sensorbased programming, and control of complex robotic systems for manipulation and locomotion. The main field of application is the robotic assistance in industrial production, medical and health-care applications up to personal assistance systems.

The chair is in close connection with the Institute of Robotics and Mechatronics of the German Aerospace Center (DLR).

Title: CoFlex TOP: A Teleoperation System for Flexible Ureteroscopy

Presenter: Christopher Schlenk


In flexible ureteroscopy (fURS) for kidney stones, the renal collecting system is inspected and stones are removed with a flexible ureteroscope (FU). One alternative to the fragmentation of stones and their removal with the help of graspers or extraction baskets is the dusting of stones with laser light. To support a single surgeon during a fURS procedure, in particular with the fine manipulation during dusting, we developed the CoFlex TOP system for the teleoperation of a handheld FU with three degrees of freedom. This paper describes the overall structure of the system, its kinematics and the hardware and software components. Subsequently, the system properties and its
position repeatability are investigated and the system’s feasibility for a tip positioning task in virtual reality is evaluated in a user study. Finally, we discuss the implications of the evaluation and sketch possible foci of a user study with urology surgeons.
