Design of hyper-redundant In-Vivo Robot: A Review

Conventional clinical process involves a large incision in the stomach to perform the surgery or biopsy to collect the infected tissue from the abdominal cavity. However, the process requires expertise and often leads to a surgeon’s tremor and patient’s discomfort. The inclusion of a robot to assist in biopsy and surgery is a boon for both surgeon and patient as it reduces the surgeon’s error in pinpointing the infected area and also results in a minimum incision requirement to do so, which is called as Minimally Invasive Surgery (MIS). In some cases, the entire robot is placed inside to do the task and called an in vivo robot. The current study focuses on the various design strategies adopted by researchers around the globe and the outcomes. This state of the art will be useful to enhance the design strategies further to refine the most cutting-edge research outcomes further.
