Digital tourniquet
Improvised elastic band, typically from a surgical glove finger or a Penrose drain, tied at the digit's base after a digital nerve block, to achieve a bloodless field; distinct from the already-catalogued pneumatic surgical tourniquet, which is a limb cuff, not a tied-off finger.
How it is used
Temporary hemostasis in matricectomies, nail avulsions, and other minor digit surgery (e.g. ingrown toenail treatment).
Clinical tip
The main risk is prolonged ischemia from forgetting to remove the tourniquet at the end; a verification protocol is needed.
