Improving the Human Factors Experience of Surgeons Associated with MSKIs/MSDs Using Medical Instruments

Abstract

Musculoskeletal disorders (MSDs) affect muscles, nerves, tendons, joints, cartilage, and spinal discs, posing significant risks for surgeons due to the physical demands of their profession. This dissertation investigates ergonomic challenges in surgical instruments, focusing on needle holders, to enhance efficiency and safety in surgery.

We conducted a systematic review to identify key issues impacting surgical procedures. Using handheld devices for 3D scans, we captured precise measurements of surgical instruments, enabling accurate redesign validation in a simulated environment. Through focus groups and semi-structured interviews, we gathered detailed insights into the ergonomic challenges faced by surgeons using needle holders.

Guided by these insights, we iteratively redesigned the needle holder to address ergonomic shortcomings, aiming to reduce physical strain and improve precision and control during surgeries. This new design is expected to enhance surgical outcomes, increase efficiency, and improve patient safety and recovery times. Our research aims to elevate surgical practice standards by providing ergonomically optimized tools for surgeons.
