  • About the Project

ShareIndia/MIMS and BITS Pilani (HYD) have collaborated in the last 4 years to develop individually tailored, light weight and comfortable sockets for below knee prosthesis. Our initial design was supported by a BIRAC grant between 2015- 2017. Our product called “Sukhfit” has been used by over 20 patients for over 2 years. Since 2018 Share-India has partially supported this project for rural populations.

  • Aims
  • Increase the strength of the prosthesis and make it more effective and longer lasting.
  • Improve our digital Imaging process to remotely collect patient's anatomical data.
  • Provide the prosthesis for as many patients as possible and make it attractive for both prosthetists and patients in the near future.
  • To provide better comfort, and maximum security for all patients at low cost.
  • Objectives
  • Main objective of the project is to provide the best fit prosthesis(SUKH- FIT) for the patients and a higher strength prosthesis at a low cost.

Our overall objective is to provide the most comfortable, individually tailored, long lasting prosthesis “Sukhfit” at an affordable cost for Indian rural populations.

The development of “sukh-fit” prosthesis involves many advanced technologies like digital 3D imaging, photogrammetry, designing and modelling software e.g AUTODESK RECAP, PTC-CREO etc. These technologies help us eliminate toxic materials like Plaster of Paris and resins used by all prosthetists in traditional prosthesis manufacture. In addition, our automated processes reduce labour and manufacturing time, thereby effectively reducing the overall cost.

We are now in the process of using patient feedback to improve our designs. These improvements include

  • Increase of strength to make it longer lasting;
  • Increase of comfort level by redesigning the liner and
  • Decrease of the cost of production by reusing waste materials, computer automation and reduced labour.
  • Status of the Project
  • We have successfully doubled the strength of the prosthesis by using strategically placed reinforcement ribs around the area where higher stresses and loads are acting.
  • We have given 5 new patients our new model “Sukhfit 2020” with the latest changes and are getting new patient feedback to continue further improvements.
  • We also made modifications to our workbench-3 model to improve quality, stability and reliability of patient's anatomy data taken in the field remotely.
  • We have developed a customized new motor with our required specifications for torque and rpms for the workbench-3 model in collaboration with Laxven Solutions Inc., Cherlapally Telangana with the requirements needed for us.
  • We applied for new formal approval of our patient testing protocol from the MIMS research Committee during this period.
