Fine workmanship, shaped like a reduced "Qi" or a flat-headed "Ge". The cutting edge is sharp and there are obvious grinding marks. Pinch with three fingers, easy to operate, like a blade, can finely cut human organs. From the point of decorative modeling, at least in the Warring States period, it can be said that it is the earliest known bronze scalpel in China!

The ancient medical technology in China can be traced back to the Stone Age, when a medical tool made of stone chips-Bian Shi was produced. According to Shan Hai Jing, "Gaozhi Mountain is rich in jade, and there are stones that can be used as needles to break carbuncle." "Su Wenyi's Theory of Fafangyi" also said: "In the eastern region ... its diseases are carbuncle, and its treatment should be stone." This shows that bian stone is a tool used to treat diseases in ancient times. Bian Shi includes stone needle, barren woman and stone sickle. There is no certain standard for their size, but they are made according to their uses. For example, "the size of the stone is made", and "The Stiffness of the Soul Pivot" says that the stone is "thin and long". It all depends on the specific conditions and requirements of the disease; But it's not too big. Based on the principle that one hand can easily hold it. For example, a stone that cuts pus and blood must have a sharp edge on one side, which looks similar to a sickle used in modern times. This is what ancient Chinese medicine called "earning" or "sickle"

According to Huangdi Neijing. Nine needles are spear needle, rod needle, hammer needle, front needle, beryllium needle, rod needle, millineedle, long needle and large needle. After thousands of years of use, the "nine needles" have evolved, and several of them are no longer used in clinic. The commonly used needles in modern times are developed from the ancient filiform needles.
