Proper sterilization is crucial to prevent surgical site infections. The Weitlaner retractor, typically made of stainless steel, can be sterilized using autoclaving. Before sterilization, it should be thoroughly cleaned to remove any biological material. After cleaning, it should be wrapped in a sterile wrap and placed in an autoclave for the prescribed cycle. Always follow the manufacturer's guidelines for sterilization to ensure the instrument's longevity and effectiveness.
