Radioactive sealed seed source chain loading system and loading method thereof

Abstract

The invention discloses a radioactive sealed seed source chain loading system which comprises magazines, a magazine box, a loading platform and a push pin. Two magazines can be loaded in the magazine box and are used for respectively placing a radioactive sealed seed source and a degradable spacer; the magazine box can move and be positioned in a transverse groove of the loading platform; through holes formed on the magazines, the magazine box and the loading platform can be coaxial with an orifice of a degradable sleeve by moving and positioning the magazine box; and the push pin passes through the round holes to push the radioactive sealed seed source and the degradable spacer in the magazines into the degradable sleeve. The radioactive sealed seed source chain loading system is simply designed, is convenient to use, is comfortable to operate and is safe; the phenomenon of leaving over or misfilling the radioactive sealed seed source and the degradable spacer can be avoided; and meanwhile, the radioactive sealed seed source chain loading system has very outstanding advantages on the aspects of simplifying radioactive sealed seed source chain loading, improving loading efficiency and reducing labor intensity and irradiated time of an operator.

Description

technical field [0001] The invention belongs to the field of tumor interstitial implantation therapy, in particular to a radioactive sealed seed source chain loading system. Background technique [0002] Radioactive sealed seed source brachytherapy for tumors is a new medical technology developed in the past 30 years. The radioactive sealed seed source is implanted into the tumor or the tissue invaded by the tumor through minimally invasive interventional technology, and the radiation emitted by the seed source core is used to kill the tumor. Kill tumor cells to achieve the purpose of treating tumors and relieving the disease. This treatment method has outstanding advantages in reducing surgical trauma, reducing complications, improving patient survival rate, and improving quality of life, especially with the successful development of 125I and 103Pd radiopharmaceuticals, the development of ultrasound and CT imaging technology and computer three-dimensional treatment The eme...

Problems solved by technology

However, at present, production personnel or medical personnel generally use tweezers to put the sealed seed source and the degradable material spacer into the degradable material casing one by one when loading the degradable sealed seed source chain. The loss and misinstallation of spacers made of degradable materials and long operation time increase the labor intensity and exposure time of production personnel or medical personnel
