Sternazip : An Innovative Surgical Device for Delayed Sternal Closure Utilizing Nano-silver Technology
Since 1957, a median sternotomy is the primary surgical approach in cardiac surgery to enable optimal exposure and access to the chest cavity. In certain conditions in which patients cannot undergo sternal closure after cardiac surgery, a Delayed Chest Closure (DSC) can be life-saving. The standard of practice worldwide is creating an oval patch from a sterile latex surgical glove to cover the heart and protect the cardiac structures from the external environment. However, this method has numerous limitations including increased risks of sternal wound infection, necessitating daily change of the glove patch to ensure sterility. As such, we would like to introduce SternaZipTM, an innovative sternal closure device fabricated from medical grade silicone integrated with nanosilver technology and designed with an interlocking zip system. The nanosilver antimicrobial properties and air-tight seal will reduce the rate of sternal wound infection and negate the need for repeated change, whilst the interlocking zip system enables rapid surgical access without the need for repeated patch removal. In line with the United Nations Sustainable Development Goals in promoting innovations and good health, this novel device will improve sternal wound care management in the short term and increase overall productivity in the long term. This endeavour is a collaboration between the Faculties of Medicine and Applied Sciences, UiTM, and Razak Faculty of Technology and Informatics, UTM. With its novelty, inventive steps and industrial application, this innovative device has been successfully filed for patent and has been recognized by the European Association for Cardiothoracic Surgery.
