MTP7.03 3D-Printed PLA Trocars in Medical Simulation Training: Cost-Effectiveness and Sustainability

Aims Recent advances in 3D printing technology have made it possible to print surgical devices, however the literature on this field remains limited. In our study we created 3D printed PLA endoscopic trocars in order to investigate if such instruments are functional and what are the benefits and the limitations. Methods We used Dassault Systems SolidWorks in order to design 10mm endoscopic cannulas, obturators and one-way valves, using plant-based biodegradable PLA and printed via SOVOL SV01 PRO 3D printers. Six 10mm trocars were created after the parts were assembled. One porcine cadaver was used and one air insufflator in order to establish pneumoperitoneum. The air leakage was monitored during establishment of pneumoperitoneum and during instrument implementation. Results The average cost of production amounted to 1.3 USD/trocar. Two trocars were used initially and exchanged with subsequent pairs for air leak measurement. Pneumoperitoneum was established successfully in every case and no leakage was identified while using the instruments, except for one case where a leak was identified and the 10mm trocar was replaced eliminating the leak. One trocar failed during the task. Conclusions The implementation of 3D printed PLA trocars can be utilized for simulation surgery and educational purposes due to their affordability and environmental sustainability.
