Problems solved by technology

[0002] The implantable chemoradiotherapy pump is a device that uses a micropump to discharge chemoradiotherapy drugs regularly and quantitatively under program control. Compared with traditional chemoradiotherapy methods, the use of chemoradiotherapy pumps can reduce the pain of patients and enhance the concentration of local drugs in the tumor Simultaneous treatment of radiopharmaceuticals and chemotherapeutic drugs can improve the curative effect of some tumors. The patent application number 201621470438.7 proposes an implantable chemoradiotherapy pump for oncology. It adopts double-layer drug capsules to effectively prevent The radiopharmaceutical outlet and the chemotherapeutic drug outlet are bonded to the muscle tissue after implantation, which is convenient for subsequent use, but their simple structure leads to poor functionality, and the timing and quantitative control of drug delivery is generally effective. Able to precisely control the amount and rate of feeding, which can easily affect the effect of treatment
