Abstract

The invention provides a drug delivery device for medical oncology. The drug delivery device comprises a movable support, an injection device and a supporting device. The movable bracket comprises a movable ring, a top plate and a bottom ring; the moving ring is erected between the top plate and the bottom ring through a moving device and is driven by the moving device to move up and down; the top of a medicine tube in the injection device is fixedly connected with the bottom of the movable ring; the supporting device comprises three groups of connecting rod structures; a screw is rotationally connected to the center of the top of the top plate, and a U-shaped frame is fixedly arranged on the outer edge of the top plate; one end of the first connecting rod is rotationally connected with the sleeve, and a rotational joint is fixed in the middle and rotationally connected with the U-shaped frame; the middles of the two rotating plates are rotationally connected with the two sides of the other end of the first connecting rod correspondingly; a fixing rod is fixedly arranged at the bottom of the bottom ring, one ends of the two rotating plates are rotationally connected with the end of the fixing rod, and the bottoms of the rotating plates are fixedly connected with a supporting plate through supporting rods. The device can support normal tissues and accurately deliver drugs to tumor affected parts.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drug delivery device for medical oncology. Background technique [0002] Antineoplastic drugs are drugs for the treatment of tumor diseases. Simply put, there are chemotherapy drugs, biological agents, etc. In recent years, the development of molecular oncology and molecular pharmacology has gradually clarified the nature of tumors. The invention and application of advanced technologies such as large-scale and rapid screening combinatorial chemistry and genetic engineering have accelerated the development process of drugs. The research and development of anti-tumor drugs has entered a new era. There are more than 80 kinds of anti-tumor drugs commonly used in clinical practice, which can be roughly divided into six categories, namely cytotoxic drugs, hormone drugs, and biological response drugs. Regulators, monoclonal antibody drugs, other drugs, and auxiliary drugs. ...
