A local manufacturer of surgical instruments produces various wire driving instruments used to set different sized pins and wires into bones of patients during orthopedic surgery. The instruments grip the wire through a collet attachment, and then spins the wire using power supplied through a handpiece. The reliability of these attachments was lower than acceptable for current product lines. This project uncovered the failure modes that caused the decrease in reliability, and recommended measures to reduce the affect of these failure modes.
