So sorry to hear about your accident. I hope you heal quickly. I cut my right index finger last fall - the cutter cut through my nail about half way down - yikes!! I didn't lose my nail, and the nurse practitioner I went to said to use super glue to hold the nail together until it grew out enough to trim. It worked and my finger is as good as new. Went through quite a number of bandaids and had to wear rubber gloves for dishwashing and cleaning. I think I learned a lesson that day on the correct way to use a rotary cutter.
