There have been countless times where the U.S.S. Voyager suffers severe damage which is 100% fixed in the next episode (or sometimes the next time the vessel is shown) despite having limited supplies and no access to a federation starbase. That's what people refer to as the "reset button".
Here's an example (both videos are from
Caretaker):
The crew were in the array between these two scenes, therefore there is no way they could have repaired their vessel. All the broken pieces have been cleared away and the Conn Panel has been fixed by the time Mr. Paris and Mr. Rollins use it even though we could see it leaking plasma and damaged enough to kill Stadi earlier on.
