Abstract
BACKGROUND: The electronic pen needle holder (EPNH) was developed to enhance surgical precision, reduce operative time, and improve patient outcomes. By integrating microergonomics, penization, and electronics with surgical instruments, the EPNH aims to provide surgeons with a tool that minimizes hand strain and maximizes control during delicate procedures. METHODS: The EPNH was ergonomically designed to fit the surgeon's hand, using titanium for its strength and biocompatibility. It was manufactured through industrial-grade 3D printing, and its mechanical properties were verified using finite element analysis. A force-sensitive resistor and vibratory mechanism were integrated to provide real-time feedback and assistance during surgeries. RESULTS: Testing by 10 neurosurgeons demonstrated significant precision, control, and efficiency improvements. The EPNH reduced hand strain and fatigue, allowing longer, more comfortable operation times. The time required for suturing tasks has decreased by 40% compared to traditional needle holders. Surgeons reported high satisfaction with the EPNH's performance and usability. CONCLUSION: The EPNH represents a major advancement in surgical instrument design, offering enhanced precision, reduced hand strain, and increased efficiency. Its innovative features and ergonomic design make it a valuable tool for improving surgical outcomes and transforming microsurgical practices.
