Bristol team refines precision of medical needles in surgical simulation

Their development is expected to improve training for junior surgeons by reproducing an effect as similar as possible to real life delivery. It will also have the potential to be used for the development of surgical robotic solutions. The breakthrough is detailed Mathematical and Computer Modelling of Dynamical Systems.

Using the theory of continuum mechanics, which focuses on the mechanical behaviour of materials modelled as a continuous mass, the team were able to develop mathematical models of flexible medical needles that are said to be computationally efficient and highly accurate. According to Bristol University, they were able to do this without introducing unnecessary steps, which reduced the computational complexity of previous investigations.

These models are crucial for developing surgical training environments for junior doctors as well as software solutions for the pre-operative planning of surgical interventions.
