In this paper, we describe a method enabling to optimally position the strain microgauges of an instrumented needle using a 3D force distribution basis, in order to explain the forces applied on the needle during an intervention.

Mots clés: needle deformation; instrumented needle; force distribution; optimal positioning of microgauges
