Problems solved by technology

[0004] However, current localized chemotherapy for giant malignant solid tumors is limited to slow-release microspheres and local implantation of rods or films
However, this method cannot achieve multi-point puncture local chemotherapy for huge malignant solid tumors, and there are still some deficiencies in the curative effect.

Abstract

The invention relates to a medical appliance, and discloses a needle for sustained-release chemotherapy. In the invention, the needle for sustained-release chemotherapy comprises a needle body (1) and a needle end (2), wherein various chemotherapeutics and thrombases are arranged on the surface of the needle body (1). The head part of the needle body (1) is sharp, and can puncture big malignant solid tumors in a multi-point way for local chemotherapy; and the needle end (2) which is similar to the fimbria of a drawing pin can be used for the force exertion during the puncturing and the compression hemostasis of the puncturing point after the puncture. Through a simple structure, the 'acupuncture' chemotherapy can be carried out on the tumors when the big malignant solid tumors cannot be surgically resected, the local medicine concentration can be obviously increased by slowly releasing the medicine, so the chemotherapy effect is increased, and the tumor burden and medicine toxic reaction during the later period of chemotherapy are reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a chemotherapy device in the medical device. Background technique [0002] In recent years, the incidence of malignant tumors in children has gradually increased, and with the improvement of the cure rate of infectious diseases, malignant tumors in children have become one of the main causes of death in children. In the United States, pediatric malignant tumors continue to increase at a rate of 4.0% every 5 years, and rank second in the cause of death in children with a high proportion of 10%, second only to 44.0% of accidental deaths. The incidence characteristics of malignant tumors in children are significantly different from those in adults. Embryonal tumors account for 50.0% to 60.0%, while the most common epithelial cancer in adults is only 3.0% to 9.0% in children. Males are significantly more than females, and the age of onset presents a double-peak trend. About 35.0% to 50.0% of them...
