AI Technical Summary
In radioactive particle implantation surgery, the existing technology is prone to infection risks when switching between different needle channels for implanting particles, and patients have a high incidence of postoperative complications.
A needle-changing sheath type puncture needle is designed, comprising a cannula, an outer puncture needle, and an inner puncture needle. By combining the cannula, the outer puncture needle, and the inner puncture needle, the needle tip of the puncture needle can be quickly replaced, reducing the risk of infection and lowering the risk of complications.
This enables rapid conversion of puncture needle functions, reduces the risk of infection for patients, and lowers the incidence of postoperative complications.
