Intracranial aspiration tubes are the most clinically used and most effective medical technique for removing liquid in the intracranial operation area, i.e. aspiration of unnecessary liquid by using the aspiration tube to act on the cranium. Intracranial aspiration tubes have been used in clinic for many years and are a traditional medical device. The suction tube is used as a necessary instrument for brain surgery, so that brain surgery is impossible without the suction tube, and the suction tube is indispensable in brain surgery because the brain tissue is softer in texture and most pathological changes can be completely sucked by matching the suction tube with the suction device after the brain tissue is diseased. On the other hand, brain tissue is rich in blood vessels, and blood vessels of the brain tissue often bleed during the operation, and when blood is accumulated in an operation visual field area, further operation is hindered, so that the blood in the operation visual field area must be continuously sucked by a suction tube and a suction device, and the operation can be continued. Another feature of the brain is that some procedures need to be performed in an environment that is full of cerebrospinal fluid, and the procedure cannot continue as well without the aspiration tube to timely aspirate the cerebrospinal fluid.

In the operation process of brain nerve tissue and cerebral blood replenishing tube in some craniums, the inside of the cranium has a complex structure when the cranium operation is performed, and for the situation that some affected points can appear on different layers, as the traditional suction tube is repeatedly used, the suction tube is bent, so that doctors can not adjust the angle to the needed angle. Meanwhile, the traditional aspirator is easy to cause unstable holding because the size of the suction force is controlled by using the thumb. Sometimes, a doctor holds a very punch for a long time after an operation for several hours.
