I think you'd at least want to sterilize it. Not sure if it's the case with these things, but other devices like endoscopes have enough cracks and crevices for stuff to hide so they have to go through an acid wash instead of steam, so the plastic probably wouldn't survive. Stuff like that either has to be non-corrosive metal or disposable.

Wouldn’t plunging them in a solution with high concentration of alcohol do the trick? (Not a medical professional, asking out of curiosity).

There are much better 'disinfectants': alcohol is good at killing living cells, but doesn't do a great job killing spores or penetrating into protein-rich....gunk.

You would probably want to use a "high-level disinfectant" or "sterilant" instead. Gluteraldyhde is fairly common choice or ethylene oxide gas, though both can be fairly nasty if not handled carefully (which is, of course, the whole point).

More emphatically: do not trust alcohol at any concentration to kill pathogens. (Likewise, freezing.)

The way alcohol swaps are used, they move contaminants away from the needle insertion site, and the alcohol helps to dislodge them. And, of course, it does kill some kinds of pathogen, as does soap.
