- W3025043535 abstract "The aim of this study was to develop and validate an ergonomically improved microforceps, which is a neurosurgical instrument used in microscopic procedures. The distance between tips of microforceps becomes large at high magnification of the operating microscope. This results in tips moving out of view and causes ergonomic discomfort. The design criteria for ergonomic microforceps were defined, which primarily involved a reduction in the distance between tips and applied force. Computer models of the existing and modified microforceps were created and fabricated using direct metal laser sintering. Ten neurosurgeons validated the developed instrument and provided feedback. In objective validation, video feed of the operating microscope was marked and analyzed by an expert neurosurgeon. In subjective validation, most of the neurosurgeons endorsed the ergonomic improvements. The parameters, including microforceps tips moving out of view (P = 0.0005), suture holding attempts (P = 0.001), and needle holding attempts (P = 0.03), were found to be statistically improved (Mann-Whitney U test), whereas the average time taken to tie 1 knot was not statistically improved (P = 0.06). The ergonomic modification also resulted in a reduction of applied force by 47.5%. Validation results show that the developed instrument provides several ergonomic benefits for the microsuturing task under high magnification of the operating microscope." @default.
