Background
Hydrocephalus is the progressive dilatation of the ventricular system caused by absorption disorder, circulation obstruction or hypersecretion of cerebrospinal fluid due to various reasons, and pressing force can be divided into high intracranial pressure hydrocephalus and normal pressure hydrocephalus. The typical symptoms of hydrocephalus are headache, balance disorder or gait instability, urinary incontinence, progressive decline of intelligence and progressive reduction of autonomic body movement, and can be clinically diagnosed by lumbar puncture drainage test. Once hydrocephalus is diagnosed definitely, LPS (lumbar cisternal abdominal shunt) has definite curative effect for such patients, is relatively safe without cranial cavity operation, and can be used as an alternative to ventricular abdominal shunt (VPS). Over the years of clinical use, the following problems have gradually emerged:
(1) the relatively sharp subcutaneous tunnel constructed by the traditional thick needle often causes that the subcutaneous tunnel and the shunt pump are not on the same plane, thus causing the epidermis to be damaged or directly penetrating into the abdominal cavity;
(2) in the traditional operation, a subcutaneous tunnel is constructed by utilizing a hollow coarse needle, and a shunt tube is led out through the hollow structure of the coarse needle, but the cleaning after the operation is difficult due to the particularity of the hollow structure;
(3) in the traditional operation, subcutaneous tissues are separated by blunt bending forceps for placing a shunt pump, so that the size of a separated space is not matched with that of the shunt pump; the separation space is too large, so that the shunt pump has a larger free space, and the shunt pump is easy to turn over after operation to influence the shunt effect; the separation space is too small, so that the difficulty of arranging the shunt pump in the operation is increased;
(4) traditional operation often leads to the shunt pump to be located directly below subcutaneous incision, and the scar that the incision formed often influences postoperative magnetic pressure regulation.

Furthermore, the end face of one end, close to the through hole, of the through strip portion is arc-shaped, and the arc direction where the end face is located is consistent with the width direction of the drainage groove.
Compared with the prior art, the invention has the advantages that:
(1) the oval disc part is designed to integrally accord with the strip-shaped structures of the liquid storage bag and the shunt valve, when an operator constructs a subcutaneous tunnel from an incision of a front superior iliac spine to a reverse Mains point, a cavity slightly larger than the structures of the liquid storage bag and the shunt valve is formed through blunt separation of the oval disc part, the phenomenon that the shunt structure overturns to influence the shunt effect after the operation due to overlarge cavity is avoided, and the phenomenon that the difficulty of placing the liquid storage bag and the shunt valve is increased in the operation due to the overlarge cavity is avoided;
(2) the invention effectively moves the liquid storage bag and the shunt valve out of the position right below the incision of the anterior superior iliac spine, thereby avoiding the influence of the operation scar at the incision after operation on the magnetic pressure regulating effect;
