Problems solved by technology

[0002] At present, various medical metal stents at home and abroad are mostly made of nickel-titanium memory alloy. The defect is that a certain amount of nickel will be precipitated, which will cause adverse effects on the human body.
[0003] In addition, these metal stents are all interventional machinery for expansion, and have no therapeutic effect on tumors. Moreover, these devices are expensive, cause great damage to the patient's normal tissue, and the treatment cycle is long, which increases the pain of the patient.

Abstract

The invention discloses a medical metal bracket which comprises a bracket main body. The bracket main body is made of nickel-titanium alloy. Both ends of the surface of the bracket main body are plated with metal layers. The middle of the surface of the bracket main body is plated with a gold layer. A medicine box is attached to the outer wall of the bracket main body. Radioactive drugs are placed in the medicine box. By the mode, the medical metal bracket disclosed by the invention can be used for preventing damage of nickel precipitation to a human body and can be used for well inhibiting cancer cells from growing, shortening the treatment period and easing the pain of a patient.

Description

technical field [0001] The invention relates to the field of special metals, in particular to a medical metal bracket. Background technique [0002] At present, various medical metal stents at home and abroad are mostly made of nickel-titanium memory alloy. The defect is that a certain amount of nickel will be precipitated, which will cause adverse effects on the human body. [0003] In addition, these metal stents are all interventional machinery for expansion and have no therapeutic effect on tumors. Moreover, these devices are expensive, cause great damage to the normal tissue of the patient, and have a long treatment cycle, which increases the pain of the patient. Contents of the invention [0004] The main technical problem to be solved by the present invention is to provide a medical metal stent, which can prevent nickel precipitation from causing harm to the human body, can well inhibit the growth of cancer cells, shorten the treatment cycle, and reduce the sufferin...
