The invention provides a radiotherapy and
chemotherapy drug delivery device, which comprises a main tube body, which is internally provided with a radiotherapy liquid channel and a
chemotherapy liquid channel which are not communicated with each other; the radiotherapy
assembly comprises a first liquid inlet
assembly and a first storage bag, the first liquid inlet
assembly is arranged at the first end of the main
catheter body and communicated with the radiotherapy liquid channel, and the first storage bag is arranged at the second end of the main
catheter body and communicated with the radiotherapy liquid channel; and the
chemotherapy assembly comprises a second liquid inlet assembly, the second liquid inlet assembly is arranged at the first end of the main
pipe body and communicates with the chemotherapy liquid channel, a first liquid outlet hole communicating with the chemotherapy liquid channel is formed in the second end of the main
pipe body, and the first liquid outlet hole is exposed out of the outer side surface of the main
pipe body and is staggered from the first storage bag. After the device is placed, accurate and effective radiotherapy and chemotherapy can be carried out at the tumor position, repeated operations are not needed, the risk that
brain tissue of a patient is injured and infected is reduced, and the service life of the patient is prolonged.
