The more common methods of removing thorns from the finger include tweezers, sterile needles and surgery. 1. Tweezers: If the finger prick is not too deep and the end of the prick is still exposed, you can use tweezers to hold the end of the prick and pull it out. 2. Remove with a sterile needle: If the stinger is deeper and the end is not exposed, you can let a professional doctor use a sterile needle to pick out the stinger. 3. Surgical removal: If the splinter is deeper, the surface of the splinter is rougher, and the location is close to important nerves or blood vessels, the splinter is usually not removed immediately, and the splinter is removed surgically after the area has hardened. If the finger prick is relatively deep, it is recommended to actively go to the regular hospital, let the professional doctor to deal with it, do not take out the finger prick without authorization. In addition, tetanus antitoxin should be injected to prevent tetanus.
