We present a new teleoperation setup for minimally invasive single-port surgery through natural orifices. The system consists of an intra-corporal parallel slave robot with two instrument arms and a corresponding master interface with four degrees of freedom and grasping. The master interface mimicks the slave robot kinematics to prevent non-achievable movements. With a workspace of ⊘ 60 mm × 85 mm,...
Single port surgery is an innovative approach in the field of minimally invasive surgery. Although several telemanipulators exist to perform operations through only a single incision they all suffer from the lack of haptic feedback. To generate kinesthetic feedback the intracorporeal forces need to be measured, which is a challenging task. To overcome these limitations we investigate in this paper...
In this paper we present a new single port robotic system particularly designed for single port access surgery in the field of colon cancer. In contrast to most state of the art systems the two intracorporeal manipulator arms are set up using a parallel kinematic structure with 5DOF, which are integrated into a shaft of 38mm in diameter. The parallel kinematic structure and its workspace are discussed...
