A novel low-cost device for tool targeting training and microsurgical hand tremor assessment

The spatial accuracy of microsurgical manipulations is one of the critical factors in successful surgical interventions. The purpose of this study was to create a low-cost, high-fidelity, and easy-to-use simulator for microsurgical skills training, which can be made by residents themselves at home. In response to the COVID-19 pandemic, we created a device for spatial accuracy microsurgical skills training and implemented it in our resident’s training program. We propose a design for basic and advanced models. The simulator consisted of commonly available products. A low-cost, durable, and high-fidelity basic model has been developed at a total cost of <10 dollars per unit. The model allows trainees to practice the critical microsurgical skills of tool targeting in a home-based setting. The developed device can be assembled at an affordable price using commercially available materials. Such simulation models can provide valuable training opportunities for microsurgery residents.
