Description

TECHNICAL FIELD

[0002] Brain glioma is the most common primary intracranial tumor caused by canceration of brain and spinal cord glial cells, can be removed by surgery, and postoperative adjuvant radiotherapy is needed. When radiotherapy is performed, the radiotherapy drug needs to be released into the intracranial brain tumor resection cavity, and the excess drug or collected liquid after release needs to be precipitated. The existing postoperative radiotherapy drug release effect is poor. For example, a kind of auxiliary device for postoperative radiotherapy of brain glioma disclosed in patent No. CN205145384U comprises a drug storage tank, a medical catheter and a balloon containing a radiotherapy drug. The drug storage tank comprises a tank body, a plug and a tank cover. The inside of the tank body has an integrated cavity with a cylindrical upper part and a conical lower part. The bottom of the cavity is provided with a catheter, and the outer surface of the upper part of the tank body is provided with external threads. The plug is a cylinder with a hemispherical body connected to the top. The top of the tank cover is provided with a hole, and the inner surface of the sidewall of the tank cover is provided with internal threads. The cylindrical part of the plug is movably connected to the cavity of the tank body, and the tank cover is threadedly connected to the tank body, so that the hemispherical part of the plug protrudes out of the hole in the top of the tank cover. This technical solution has certain defects for postoperative radiotherapy of brain glioma. The release of the drug and the collection of the liquid in the intracranial brain glioma resection cavity exist certain problems. The collected liquid and the drug release are uniformly realized through the balloon. When the collected liquid in the balloon is completely extracted through the syringe, the balloon will shrink, and cannot support the side wall of the intracranial brain tumor resection cavity, causing the side wall of the intracranial brain tumor resection cavity to shrink. If the collected liquid is not completely removed, the drug will mix with the collected liquid when the drug is injected into the balloon again, affecting the release of the drug and reducing the drug release effect.
