If the sole of the foot is stabbed with a wooden thorn, if it is relatively shallow, and the wooden thorn is partially left outside, the wooden thorn can be directly removed and the wound can be disinfected. If the splinter is deeper, and the splinter is not easy to pull out because it is basically sunk into the flesh, you cannot squeeze the local skin rashly, otherwise it will easily make the splinter sink deeper. If the wound is too deep and the pliers cannot be used to pull out the splinter smoothly, it may be necessary to cut the wound open and expand it, then use smaller pliers to pull out the splinter, disinfect the wound thoroughly with hydrogen peroxide after pulling it out and dress it, then give a tetanus shot.
