摘要:
A force-sensing tool includes a tool shaft that has a proximal end and a distal end, a flexure section attached at a first end to the distal end of the tool shaft, a tool tip operatively connected to the flexure section such that axial forces applied to the tool tip are coupled primarily to a first portion of the flexure section and transverse forces applied to the tool tip are coupled primarily to a second portion of the flexure section, an axial force sensor coupled to the first portion of the flexure section, and a transverse force sensor coupled to the second portion of the flexure section. The axial force sensor responds to axial forces applied to the tool tip substantially independently of the transverse forces applied to the tool tip under a designed operating range of forces, and the transverse force sensor responds to transverse forces applied to the tool tip substantially independently of the axial forces applied to the tool tip under the designed operating range of forces.
