Will the new circular external fixator ease the surgeon’s burden?

While the country is still recovering from the internal conflict that plagued it for over three decades, the shadows of these dark days still haunt these lands. The Sri Lankan soil is still not completely rid of antipersonnel landmines which were once weaponized against military and civilians alike. A more recent terrorist attack that happened in 2019 rekindled this age-old fear against explosions in the hearts of Sri Lankans. While prevention of such disasters is important, realistically, it is the duty of engineering researchers to equip medical professionals with devices that can aid and expedite the treatments if and when such unfortunate disasters occur.

A 3DOF transtibial robotic prosthetic limb

These devices are intended to return the amputees to their pre-amputation functional status. Below knee (Transtibial) amputation is the most common amputation occurred in the lower limb. That is caused by reasons such as diseases, injury due to explosions of anti-personnel land mines and accidents. The existing prostheses for transtibial amputees have yet to be improved to reinstate the biomechanical functions normally provided by the ankle joint. Therefore, the purpose of this research is to develop a transtibial robotic prosthesis which would provide functions usually provided by the ankle. The proposed design consists of 3 Degrees of Freedom (DOF) to generate similar biomechanical motions at the ankle joint. Further it includes a passive regenerative system to reduce motor power requirement of dorsiflexion/plantarflexion. Experiments are carried out to verify the effectiveness of the proposed prosthetic limb and to verify the possibility of using electromyographic (EMG) signal based control of the prosthesis.
