Abstract
Abstract The global shortage of healthcare staff has led to high workloads and subsequent risks to patient well-being. One of the professions affected is that of the scrub nurse. Robotic scrub nurse systems have the potential to reduce workload and to assist in handling surgical instruments. Existing approaches mostly use two-finger grippers or electromagnetic grippers. However, it is assumed that a granular jamming gripper is more suitable for handling various surgical instruments, regardless of material and shape. A gripping unit based on a granular jamming gripper and attached to a robotic arm is presented. For evaluation, six surgical instruments were repeatedly gripped and transported. The granular jamming gripper was found to be suitable for picking up and transferring most instruments, however, handling very flat instruments turned out to be challenging.
