Abstract
Surgical robotics is an evolving field where robotic medical devices are utilized to perform surgery either on or within the body. In order to mitigate errors that may occur during surgery due to the medical devices being used, testing environments are created for better development of the device and for clinical training. A Pulsatile Flow System (PFS) is a machine that recreates the physiological conditions of flow rate and pressure as the heart pumps blood, and can be created using materials such as pipes and motors. The research at hand developed a PFS and specifically focused on the electrical components of the system, using a motor, a motor controller, a flow sensor, and a circuit board. By creating code that is able to control the system and the speed at which the PFS functions, the system was able to pump water at 40 beats per minute through the circuit. Moving forward, the PFS can be improved to become an even more accurate model by including changes such as substituting the water in the system with a liquid of a similar viscosity to blood. The development of a machine like this is crucial in order to provide a cost effective system capable of imitating the human body in order to properly test surgical robots that travel through arteries in the body. Using an external testing environment will ensure that the devices created in the laboratory are properly developed before they are used in surgery, ensuring that the patient’s life is kept out of harm’s way.
