Development of haptic simulator for practicing the intraarticular needle injection under echography

Intraarticular needle injection under ultrasound guidance is the most used method to provide pain relief in joints. To learn this process, medical students need to practice in order to master the manipulation of the syringe and the ultrasound probe at the same time. To offer a risk-free training for trainees, we present in this paper the development and design of a haptic simulator prototype. The models and methods used to render the forces involved are introduced, as well as the mechanical design and finally a validation test performed by our medical partner.Clinical relevance—This simulator helps medical students to train intraarticular needle injection under ultrasound guidance using a haptic device to provide realism and immersion.
