Biomimic material mold for 3d modeling new surgical tools

thingiverse

Mold for biomimic materials such as agar or polyacrylamide is designed to model new surgical tools like bipolar forceps or ultrasonic aspirators. The T hole array is intended for temperature monitors, including thermocouples. Two holes on the side are made specifically for current monitors. Holes are engineered with a taper so that they can be inserted easily but not removed accidentally. Agar can be easily turned into a gel by mixing it with water and heating until boiling point is reached. To prevent it from solidifying, it must be kept at approximately 90°C. It can cool to around 45-50°C before being poured. For more information, visit https://www.doane.edu/agar-and-plate-preparation. Polyacrylamide is more challenging to prepare and is made by polymerizing acrylamide monomers and bisacrylamide. The polymerization reaction is initiated by ammonium persulfate (APS) and catalyzed by tetramethylethylenediamine (TEMED).

Before pouring the gel into the mold, temperature and current monitors should be inserted. An Arduino was used to record data but it was part of a senior design project at Michigan Tech and cannot be shared.
