Innovative surgical precision: The electronic pen needle holder based on neurophysiological principles.

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.
