Development of Assistive Medical Device Based on Reverse Engineeringand Biomechanics
The paper presents an innovative process of designing elastic braces to protect injuredjoints.Based on the included box of 3D scanned data from the injured joint,a smallish tentativeelastic brace is designed.The strain energy is derived from the strain energy density function,which isthe function of the dimension of the brace,elastic materials parameters and the motion of the joint.The stiffness is then confirmed by the derivative of the strain energy.Compared to the stiffnessprescribed by the physician,the modification of these parameters is done until it meets therequirement.For effective calculation,mesh simplification and parameterization techniques areapplied,which have been widely investigated in computer graphics field.The proposed approach tostrain energy and stiffness calculation makes it available to design a custom-made elastic brace forinjured joints.The simulation results prove it work quite well for designing medical assistive devices.The research is useful for developing medical devices and intelligent robots.
