Electromagnetic Field Smart Splint for Bone Fixing and Rehabitation Using NiTi Shape Memory Alloy

摘要

Patients who suffer from broken bone could be prescribed splints to support their treatment procedures. The normal fabrication style of tailored splints is talent dependent long and also the splints themselves create varied issues with regards to the patient's response. Between many different special characteristics of Shape Memory Alloys (SMAs) that they have the power to come to an original form once heated. However, the general modification of associate degree existing part will powerfully be affected by the thermal and thermo-s mechanical properties. Therefore, shape memory alloys have been discovered numerous materials, which may typically be classified into Nobel-metal based mostly, Cu based, Fe based, NiTi alloy based system and metalloid shape memory alloys. Electrical stimulation has been applied to a number of different ways to influence tissue and bone healing. Most of the early works were carried out by orthopedic surgeons looking for new ways of enhancing fracture healing, especially those fractures that had developed into nonunion. Electrical energy can be supplied to a fracture by direct application of electrodes or inducing current by use of pulsed electromagnetic field or capacitive coupling. Many of these techniques have not been standardized.
