Abstract
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, it is 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.
Claims14
An electromagnetic heating unit configured to heat a part of an orthopedic implant component having a female taper comprising:
- a primary coil and secondary coil wrapped around a common iron core which generates a high induction electrical output transmitted to a heating element situated in a heating chamber which heating element dissipates heat imparted to the female taper part of the orthopedic implant component.
