About the project
This project, in the field of ultrasonic surgery, focuses on the development of cutting-edge miniature ultrasonic devices targeted for bone surgery. It seeks to advance the current state-of-art design by introducing new configurations and incorporating novel structures in miniaturised devices to enhance precision and improve clinical outcome.
Ultrasonic surgery has attracted growing attention for its potential to provide minimally invasive alternatives to conventional procedures, offering advantages of low force, high precision, tissue selectivity, reduced collateral damage, and faster post-operative recovery. However, the current state-of-the-art ultrasonic surgical devices are predominantly based on single or multiple half-wavelength resonators, which present significant challenges for integration with the flexible endo-wrist mechanism of surgical robots, thereby limiting their applicability in complex minimally invasive interventions.
This project seeks to transform the design of conventional ultrasonic transducers by introducing novel configurations and advanced structures for miniaturised surgical devices. The research will investigate various classes of flextensional configurations to evaluate their potential for device miniaturisation through both modelling and physical prototyping. In parallel, metamaterial-inspired structure will be incorporated to tailor vibrational behaviour and achieve controlled dynamic responses.
You will join the Mechatronics and Bioengineering research groups at the department of mechanical engineering, and have access to 3D X-ray histology, imaging, metal 3D printing and other advanced facilities. You will also carry out in vitro and in vivo cutting experiments at the Southampton General Hospital. The supervisory team bring together expertise in ultrasonic surgical devices, metamaterials, and additive manufacturing, ensuring comprehensive guidance and professional support throughout your research.
This project will provide you with a strong foundation in ultrasonics and advanced materials, opening diverse career opportunities in academia, research, and industry. You will be well-positioned for roles in cutting-edge medical technology companies and healthcare innovation.
