It is understandable that you might be confused about the term that is often used but hardly explained. Minimally invasive surgery means smaller incisions. Hence, when you are talking about minimally invasive surgery it means that the surgery can be performed without bigger incisions. There are several benefits of such type of surgery. Since smaller incisions are made, scarring is much lesser and the healing time is faster. There is less blood loss and there is a lesser risk of infection which means speedy recovery as well. This is why robotic surgical systems are great.
