Development and analysis of a magnetic compression spring for minimally invasive applications

This research paper focuses on the development and analysis of a magnetically actuated helical compression spring designed for minimally invasive medical applications, such as targeted drug delivery. The spring is fabricated from a mixture of polydimethylsiloxane and iron-nickel powder, enabling the spring to respond to different strengths of externally applied magnetic fields. The effects of iron-nickel powder composition and spring design on its mechanical behavior are investigated. The results show that the spring’s compression force increases with an increasing magnetic field. The spring’s behavior is influenced by the iron-nickel powder composition and design. This research demonstrates the potential of magnetically actuated helical compression springs for minimally invasive medical applications, such as targeted drug delivery. The spring’s ability to respond to external magnetic fields enables precise control over its compression and decompression behavior, making it promising for future medical applications.
