In Vivo Usability Test of Vascular Intervention Robotic System Controlled by Two Types of Master Devices

Conventional vascular intervention (VI) procedures are typically performed manually under exposure to X-rays, whereby several problems presented that need be addressed owing the patients and doctors being exposed large amounts of radiation. In such cases, employing radiation protection units is not a long-term solution avoid physical damage. Therefore, overcome these issues, we propose robotic VI system in this study. Moreover, compare extent case conventional manual procedure with procedure. The then analyzed from perspective doctor. Subsequently, results usability tests for two proposed master devices terms NASA task load index (NASA-TLX) scale (SUS) score. To verify effectiveness system, animal experiments conducted using pig model. Among types tested ergonomically designed 2-degree-of-freedom device found more effective than joystick-type test scores. Hence, shown advantageous reducing improving usability.
