What are their functions?

1. Support for fine operations: Instruments like surgical microscopes, micro forceps, and micro needle holders provide a magnified and clear view and enable precise operations for the repair of nerves, blood vessels, and tendons (such as finger replantation), ensuring the quality of suturing and anastomosis at the microscopic level.
2. Bone tissue handling: Electric drills and electric saws can cut and drill bone tissue; internal fixation instruments such as Kirschner wires, mini plates, and screws can stabilize fractured bone ends (such as fractures of fingers and toes); bone chisels and rongeurs can trim bone tissue to assist in deformity correction (such as hallux valgus and hammertoe repair).
3. Surgical field and tissue management: Retractors can retract skin and muscles to expose the surgical area; hemostats and electrocoagulation devices can stop bleeding efficiently and reduce intraoperative blood loss; needle holders and suture needles/threads are used for wound and soft tissue suturing.
4. Specialized treatment for foot diseases: Podiatric instruments such as nail clippers and corn knives can specifically address foot problems like calluses, ingrown nails, and hallux valgus; specialized tools like calcaneal distractors can create operating space for complex foot and ankle surgeries (such as calcaneal fracture repair).
5. Postoperative care assistance: Improved lamp shades for therapeutic lamps can gather heat and facilitate observation after finger replantation and flap repair surgeries, enhancing nursing safety and patient comfort.
