Sorry, but I've got exactly as far as you.
I'm sure the "but doctor" at the beginning of the clue must mean something and also "smashed the designer".
But I've got the same designer and the same doctor.
So like you I'm getting nowhere.
Unfortunately I haven't managed to solve No.16 yet - which may have a link to this clue.
Any more help from anyone on clue 17 would be welcome.
