OpenSurgiSim by AlgoSurg

OpenSurgiSim training module will enable any orthopedic surgeon/trainee to acquire the cognitive and psychomotor skills required for performing complex bone-deformity surgeries of Spine, Lower-limb etc.

Key features:

- Decision-making training through virtual interactive 3D simulation of bone deformity-correction surgeries on many real-world complex cases

- Psycho-motor training on 3D printed bone models, with low-cost WebCam-based Augmented-Reality (AR) system, for real-time feedback (by tracking surgical tools/hands)

- Innovative design of the 3D printed bones with 10 times lower cost

- Web-software easily accessible anywhere with PC/mobile/tablet

- Modular design - Easily scalable to any anatomy and surgery (eg: spine, dental and even laproscopic in the future)

Self-assessment is based on AR-based feedback on the resulting surgery performed on the physical 3D-printed bone and critical improvement suggestions

OpenSurgiSim is easily-accessible and easily-reproducible and it has three parts:

Virtual Training on easily-accessible web-app. This includes interactive and guided 3D-simulations of complex bone deformity-correction surgeries performed on virtual deformed bones, matching range of real-world patient cases. Trainees will learn how to apply surgical techniques (decision making based on principles of deformity-corrections) on different kinds of complex cases.

Psycho-motor Training includes performing the above-mentioned learned techniques on physical 3D-printed models of the same deformed bones used in the virtual training. For this, we have devised a novel design of the 3D-printed bones to reduce its cost by at least 10 times. 

This physical training will be performed under the vision of our innovative low-cost WebCam-based AR system to give real-time guidance (by tracking hands and surgical tools; NO AR glass required). This will make trainees to acquire critical psychomotor skills required to perform complex bone deformity-corrections.

Self-Assessment includes our low-cost AR-based evaluation of the resulting deformity correction performed on the physical bone-models. The evaluation will include checklist of critical surgery steps and quantitative as well as qualitative measure the surgical outcome. Computer vision and image processive algorithms will be employed for this.

Complex bone deformity corrections (lower-limb or spine) require special cognitive and psychomotor skills which are based on highly researched principles of deformity corrections. This may involve accurate evaluation of bone deformity in 3D space, exact numbers, position and orientation of bone resections, ways of repositioning of bone segments, evaluation of resulting bone correction etc. These techniques may vary case-to-case and become complex for complex deformity cases. 

Need - To acquire these skills, a trainee surgeon has to work under highly expert surgeons for years, performing many real-patient cases. Hence, there are a very few highly skilled deformity correction surgeons in the world, especially in the low-resource settings, where most of the complex cases occur. The surgeons at low-resource settings either send the patients to the expert surgeons at high-resource settings or they under-perform in the surgery which has to be re-visioned by expert surgeons later, adding extra cost to the patient while declining their life-style quality. This also adds a huge work load on the expert surgeons.

Hence, we are developing a low-cost, easily-available and easily reproducible training module to make any orthopedic surgeon highly skilled to perform complex deformity corrections at highest quality, anywhere in the world.

OpenSurgiSim will enable any orthopedic surgeon/trainee to perform expert level bone deformity correction with high quality of surgical outcome at a very low cost. The techniques, principles and skills which otherwise could be learned only by working with highly expert surgeons at high-resource settings, will now be learned using simple phone/tablet/pc with web-camera and innovatively designed low-cost 3D printed bone models, without a need of expert guidance. This solution will also improve patient outcome and reduce the load of expert surgeons.

We worked with a highly-skilled surgeon (Dr. Mangal Parihar and his trainees) and developed 3D surgery planning/simulation software (Tabplan3D) for his use. The surgeon used the software to improve his surgical outcome and to train the same to his fellow trainee surgeons. This is where the surgeon conceptualized the idea of pivoting the technology used in the software (i.e. 3D planning) towards the training purpose, so that any surgeon can perform like Dr. Mangal Parihar.

Hence, we are developing "low-cost surgical training system based on 3D-simulation and 3D-printed models with AR-based self-assessment", with the surgeons (like Dr Mangal) themselves and now they are helping us to build and test the same, in their own clinical facilities.
