title: A proof-of-principle robot with potential for the development of a hand-held tactile instrument for minimally-invasive artery cross-clamping.
abstract: One of the most common diseases of the vascular system is abdominal aortic aneurysm (AAA), for which the most definitive treatment is surgery. Minimally invasive aorta surgery is a novel method of surgery performed through small incisions and offers significant advantages including less pain, shorter hospital stay, faster patient recovery, less possibility of infection, etc. However, lack of sense of touch is the main drawback of this type of aorta surgery that would incapacitate the surgeon to exactly distinguish the aorta from its surrounding tissues which could cause various problems during the aorta cross-clamping process. One of the most important drawbacks is that it makes the aorta cross-clamping process the most time-consuming process of aortic repair surgery. The artificial tactile sensing approach is a novel method that can be used in various fields of medicine and, more specifically, in minimally invasive surgeries, where using the 'tactile sense' is not possible. In this paper, considering the present problems during aortic-repair-laparoscopy and imitating the movement of surgeons' fingers during aorta cross-clamping, a novel tactile-based artery cross-clamping robot is introduced and its function is evaluated experimentally. It is illustrated that this new tactile-based artery cross-clamping robot is well capable of dissecting an artery from its adjacent tissues in a short time with an acceptable accuracy.
