MRI-guided robotic system for transperineal prostate interventions: proof of principle.

In this study, we demonstrate the proof of principle of the University Medical Center Utrecht (UMCU) robot dedicated to magnetic resonance imaging (MRI)-guided interventions in patients. The UMCU robot consists of polymers and non-ferromagnetic materials. For transperineal prostate interventions, it can be placed between the patient's legs inside a closed bore 1.

A versatile tool for exposure in minimally invasive surgery.

Background: Endoscopic surgery in a major cavity in the body requires space for manipulation and presentation of the target organ or site. For coronary artery grafting on the working heart, additional local cardiac wall immobilization is indispensible.

Methods: A passive hydraulic arm was developed to be mounted on the operating table rail.
