This example seems to work; see if it helps you:

import pymongo

db = pymongo.MongoClient()['mydatabase']
db.mycollection.delete_many({})
db.mycollection.insert_one({'path': 'You Now Have \"Two Problems\"'})
name = 've \"tw'
query ={"path" : {"$regex" : name , "$options" : "i"}}
print(list(db.mycollection.find(query)))

Result:

[{'_id': ObjectId('5e18c97d2b0b356dbd0019a1'), 'path': 'You Now Have "Two Problems"'}]
