Full Time 40 hours Grade 054 Urology M&DResponsibilities
Research and Development (70%)
The fabricating of high-fidelity perfused hydrogel organs for surgical simulation. This process involves:
Segmenting patients’ DICOM images to a 3d mesh using Mimics Innovation Suite
Converting the 3d mesh into computer-assisted designs (CAD) using Autodesk Meshmixer
Optimizing the CAD by smoothing, and removing artifacts
Ensuring accuracy of the CAD in comparison to the patients imaging
Designing injection molds from the CAD of the patient anatomy
3D printing of the various molds for structures in each organ
Fabrication of the various structures including hollow vessels for perfusion
Registering the fabricated structures into their corresponding molds
Injecting and processing the hydrogel to fabricate the organ
Ensuring accuracy of the organ and its lack of defects
Layering organs into the body cast to create the surgical rehearsal platform
Supervising the surgical rehearsal
Design and fabrication of generic models for novice training. These models include (put in everything urology and non -urology)
Prostate Nerve Sparing
Advanced trainer (robotic and open)
Pelvic Lymph node dissection
Major Vascular Injury (robotic and open)
US PCNL access model
Kidney Transplant (Donor and Recipient)
Biomechanical testing of various PVA formulations to create a realistic texture for each of the components of the fabricated organs.
unconfined compression testing
Hertzian Indentation testing
Uniaxial tension testing
Porcine testing mainly for kidney models
Bovine testing for live models
Recently testing of fresh frozen cadavers
Device: Instron 5960: Electromechanical Universal Testing Instrument. The most common uses of these mechanical testing systems are for tensile, compression, bend, peel, shear, tear and cyclic tests.
Analysis of data
Prototyping new models, a new model is developed almost every 6 months. The process involves
Interfacing with customer to gather design specifications
Review of current literature and advances in the field
Presenting a digital design
Testing of various components of the simulation (partial teak trainers)
Delivering the first prototype
Interfacing with customer in a hands-on session to gather modification specifications
Delivering the final prototype
Attending the simulations in person to obtain 1st hand feedback from the surgeons
Focus groups with expert surgeons
Create and implement new research protocol.
Recommend solutions/revisions to the study team in order to focus the aims of the study
Design the protocol around abilities of participants
Confirm expectations of models to be produced
Gather data during each simulation
Draft research papers and grant proposals.
Analyze data and arrange into meaningful figures
