Cerebral hemorrhage is caused by bleeding from a rupture of a small artery inside the skull, where the blood flow in the intracranial arterial vessels is faster and more pressurized. When bleeding occurs the locally formed blood clot seals the breach in the artery, stopping the bleeding temporarily. However, the gap sealed by its own blood clot is not solid, and it is easy to cause the blood clot to be washed away when there is emotional excitement, elevated blood pressure, and increased impact of blood flow, which triggers re-bleeding and leads to the expansion of the hematoma, and even the need for craniotomy. At the same time when craniotomy is needed, it is necessary to apply bipolar electrocoagulation to coagulate the localized broken small blood vessels, so as to make small blood vessels constricted and occluded, and thus make the bleeding stop.
