Abstract

The invention provides a radioactive particle chain. The radioactive particle chain includes a soft tube having good histocompatibility and equivalent effects of radiotherapy tissue; one end of the soft tube is closed, and the other end of the soft tube is movably connected to a baffle sheet, wherein the area of the baffle sheet is greater than a cross sectional area of the soft tube; and radioactive particles are arranged in the soft tube. The radioactive particle chain can determine initial treatment dose through the characters of a tumor; periodic review is performed after the radioactive particles are arranged in the tumor; when the size of the tumor changes, the number of the radioactive particles can be increased or decreased by inserting or pulling out the radioactive particles, and then the dose of the radioactive particles can be controlled conveniently after the radioactive particles are implanted into the tumor; all the radioactive particles can be taken out when the tumor vanishes or a patient dies; and the complication can be reduced, and radiation to the patient or public can be decreased. The radioactive particles used in the patient can be disinfected and reused in tumors in other parts of the same patient after being taken out, and then medical resources can be saved, and the patient can accept the radioactive particles in mind.

Description

technical field [0001] The invention relates to the technical field of radioactive particle implantation, and more specifically relates to a radioactive particle chain and a method for using the same. Background technique [0002] Malignant tumors have always been a major disease that threatens human health, and interstitial brachytherapy of tumors using radioactive particles is a new technology developed in recent decades. Radioactive particles are a small radioactive source. The radioactive isotope is packed in a titanium tube, and the two ends are welded by laser or electron beam technology to form a sealed source. The size is generally 0.8mm in outer diameter and 4.5mm in length. Commonly used nuclides for radioactive particles are 192Ir, 198Au, 169Y, 131Cs, 103Pd and 125I, especially 103Pd and 125I. Brachytherapy is to implant radioactive particles directly into the lesion, continue to irradiate at close range, and then destroy the DNA double bond of the tumor cell nuc...
