Thermally securing Morse taper

摘要

An articular ball impactor having a heat resistant material used during “heat shrink fit” process for providing secure fixation of Morse taper components in modular orthopedic implants. The female Morse component of the articular ball is heated by electromagnetic unit providing thermal expansion. Subsequently, itis impacted over the male Morse taper component and then cooled by commonly used sterile irrigation fluid allowing the female Morse component to shrink thus providing considerable compression, fit and significant reduction of micromotion that has been so widely responsible of fretting and mechanical corrosion.
