[0007] In order to enhance the sealing between the inner wall of the sleeve and the stopper, an annular embedding groove is provided on the stopper, and a sealing ring is embedded in the embedding groove. The sealing ring is made of silicone or rubber.
[0008] In order to make the rotating crushing component rotate to crush the hematoma, a connecting rod is formed at the other end of the boss, and a rotating handle is connected to the other end of the connecting rod.
[0009] In order to guide the sucked hematoma, the suction hole is a strip-shaped long hole opened above and below the catheter, and the hole wall has an arc-shaped or sloped structure.
[0010] In order to reduce the resistance of the drain entering the brain tissue and reduce trauma, the end of the catheter is a bullet-shaped tip.
[0011] In order to control the depth of the drain into the brain, graduation lines are laser engraved on the surface of the catheter.
