I love optimism...
Lets save your snake. I initially envisioned much worse, "sliced up" and all that.
I am not a veterinarian, nor even remotely so.
Betadine, one can buy a small bottle at a good drugstore.

The following is "M.K.'s" Procedure for Treating Minor Wounds, Blisters, Burns
1.Soak the reptile in warmish chest deep water to which Betadine (povidone-iodine) has been added to color the water to a deep medium tea color.
Leave in the tub for 15-20 minutes, refreshing the warm water and Betadine as necessary.
If the wound is swollen and crusty, carefully pick off the scab/crusty exudates.
Note that if the reptile defecates in the tub, it must be washed out, disinfected and another Betadine soak set up.
Flush the wound area with fresh water before being placed back in the new bath.
2.Remove the reptile from the tub and flush the wound with fresh dilute Betadine.
3. At night, top the wound with triple antibiotic ointment. Repeat for a week or until the wound is healing over.
4. If there is any sign of swelling which occurs after the bathing and treatment or such swelling does not abate after a week, the animal must be seen by an experienced reptile vet.

A 10 -25 (use 25) drop per gallon of G.S.E. per gallon will also do the job if you happen to have some handy.
I use ten drops per gallon in my everyday drinking water for my corns, and since we are "flying by the seat of our pants" here, whatever that means, it just may help by stimulating naughty bacteria fighting abilities in the patient.
GSE, according to published sources, is effective against more than 800 bacterial and viral strains, 100 strains of fungus, as well as a large number of single-cell and multi-celled parasites.

Some will advise to shoot that puppy up with anti-biotics,
but I'm assuming thats beyond the scope of a home remedy for most hobbyists.
Let air dry in your immaculately clean tank.
Then apply a topical antibiotic salve.
Walgreens Drugstore chain sells a brand of triple antibiotic salve that also has Aloe Vera And vitamin E in its formulation. Good stuff.
Will accelerate the healing process.
As was stated above use Newspaper/ paper towel, so substrate does not stick to the wound.imho.
