Patent ID: 10962093

Abstract:
Disclosed is a steerable tool with proximal and distal ends comprising a mechanical transmission system (MTS), shaft region, omnidirectionally moveable bendable proximal part (BPP), and omnidirectionally moveable bendable distal part responsive to movement of the BPP, where the MTS comprises longitudinal members (LM) each having proximal and distal ends, arranged in a longitudinal direction around a fictive tube, and has a corresponding transmission shaft region (TSR), transmission bendable proximal part (TBPP) and transmission bendable distal part (TBDP), wherein a plane section of at least one LM has an anisotropic area moment of inertia, and the majority of the LMs are axially rotationally constrained at one or more constraining points along the TBDP or TSR, the LMs are longitudinally slidable with respect to each constraining point, and the MTS is configured such that the TBDP tip is axially rotatable in a bent position by a complementary rotation of the TBPP.
