This was already answered for you - there is no risk for any STD, including syphilis.
To get syphilis, you need to have some kind of sexual activity - oral, vaginal or anal sex. You didn't have any of that. There is no such thing as a "medical exposure" to syphilis. It's not a blood-borne pathogen.
Your question has been answered that this is not a risk.

Sorry Jessi, really thanks for your answer. I want to know that syphilis can also be transmitted by transfusion, but you mentioned it is not a blood-borne pathogen, then how does it transmit by blood?
Thanks!! That really helps me a lot
