Add method(s) to repair prosthetic organs without surgery.

Title. We are in the future where we already have magic chems that repair chemical neglect from livers, bulletholes in lungs and hearts. And brain juice that reverses traumatic brain injuries. Why don't we have something similar for mechanical organs? I can suggest a few ideas;

Nanoline, a cryo chem that slowly heals all mechanical organs and perhaps limbs as well. Could make sense for machinists to have too, for the occasional IPC that comes in half melted to death from their failing coolant systems.
Nanite inhaler. Heals only prosthetic lungs.
Access ports. Small ports in the chest/abdomen that allows machinists/doctors to access and diagnose prosthetic organs without surgery. Perhaps a unique tool for this purpose, like a diagnostic bore scope or something.
Or some generic chem that acts like peri/adip/pneumalin but for mechanical organs.
