Depends where the surgeons are working. If it’s on an arm or a leg then a tourniquet can be used to temporarily stop the blood supply to the limb.

Generally though the ‘cut wide open’ thing is avoided wherever possible. “Keyhole” surgery has been one of the biggest advances of the last 30-ish years.
