The spikes can be removed by hand, with instruments, and by cutting the skin to remove the spikes from the flesh.
1. Extraction by hand: When a spike is lodged in the flesh, it should first be extracted by hand and the skin should be sterilized routinely to prevent infection.
2. Removal with instruments: If the spike is small or the exposed end of the body is short and cannot be pinched by hand, you can consider instruments such as tweezers and hemostatic forceps to hold the spike and then pull it out.
3. Cutting the skin to remove: If the stump of the spike is not visible on the skin surface, it can be removed by local firm anesthesia and picked out with a sterile needle, or cut the skin to remove the spike.
4. Other treatments: If the spike is lodged in the flesh, and if it is deep enough to form an anaerobic environment, it is also necessary to inject tetanus antitoxin in time to prevent tetanus bacillus infection.
If there is a spike in the flesh, it is recommended to go to the hospital for examination and treatment as prescribed by the doctor.
