Hip implant force measurement: Design of an intraoperative hip joint 3-DOF force measurement system

Achieving appropriate soft tissue tension around the hip joint is an important factor for achieving hip stability after Total Hip Arthroplasty (THA). Hip instability leads to dislocations, pain, and is a common reason for early revision surgery. The current soft tissue tension assessments available during surgery rely on experience, and...

Rendering 6-DOF Object-to-Object Interaction with 3-DOF Haptic Interfaces

Three degree-of-freedom (3-DOF) tool-based haptic interfaces are widely used in virtual environment to train operators, and for virtual prototyping and design. In some special cases with higher requirement on haptic fidelity, the tool needs to be modeled as an object with real volume rather than a single point. However, such object -to-object...
