Title: Steerable flexible needle with embedded shape sensing function
Inventor: VINCENT DUINDAM
IPC: A61B34/20
Filed: 2017-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a steerable needle system that can be effectively used in minimally invasive surgical procedures.SOLUTION: A surgical system includes a flexible steerable needle and a shape sensor for measuring the shape of the needle.
