1.Combined spinal anesthesia needle: The needle tip is unique and can effectively prevent cerebrospinal fluid leakage.

2. Epidural puncture needle: The head of the epidural puncture needle is electrolytically passivated to prevent the catheter from being cut when it retreats in the needle tube.

3. Spinal anesthesia needle: rigid, tough, and easy to puncture.

4. Anesthesia puncture needles (hard anesthesia needles, spinal anesthesia needles, combined needles): The needle seat is transparent for easy observation, the locking device can help the needle seat bayonet lock the direction of the needle tip window, and the needle core seat uses different colors to distinguish different specifications.

5. Soft-head epidural anesthesia catheter: The outer 3-5 mm of the catheter head is softened and the hardness is reduced by about 30%, which can effectively prevent dural punctures.
