Mini aortic valve replacement retractor is a device designed to dilate the aortic valve in a minimally invasive aortic valve replacement (Mini AVR) procedure. Where the incision is small, and the pathological condition is deep, the operation field is limited.This retractor would facilitate the surgeon to see the surgical site in the narrow space of the deep cavity. The Mini AVR retractor is made from stainless steel, similar to surgical
tools. The inventing process of this device is simple and inexpensive. A set of Mini AVR retractors consists of flexible, six-sized blades with a small and long handle. The Mini AVR retractor has advantageous characteristics in its flexible blades, which can be chosen to suite the aortic valve. In addition, a small and long handle can reach the aortic valve position, and it is easy for the surgeon’s assistant to hold. At the same time, it does not interfere with the surgeon’s eyesight during the operation. These characteristics will
facilitate the surgeon to conduct the surgery quickly and safely. Also, this product is low-cost. Results from the evaluation by surgeons and scrub nurses using the Mini AVR retractor revealed that the mean score of overall satisfaction with this device was at the highest level. Thus, the Mini AVR retractor should be applied to improve the procedure quality for minimally invasive aortic valve replacement.
