Embodiment Construction

[0032] The medical sodium iodide implant of the present invention adopts a radioactive isotope that is very suitable for permanent implantation in the human body 125 I, the carrier is selected clinically confirmed medical polyurethane, medical silicone rubber, medical latex or gelatin (Gelatin) that has been used for human implantation for a long time.

[0033] Medical sodium iodide implant provided by the invention, its treatment source uses radioactive isotope 125 I, medical polyurethane, medical silicon gel, medical latex or gelatin (Gelatin) are used as its implant carrier, and the present invention also provides the manufacture method of this kind of medical sodium iodide implant.

[0034] The shape of the present invention may be film, sheet or sponge.

[0035] The radioisotope of the present invention 125 I ions are evenly distributed in medical polyurethane, medical silicone gel, medical latex or gelatin (Gelatin).

[0036] Radioactive isotopes provided by the inven...

Abstract

A medical sodium iodide implant for human body to treat or suppress the cranial nerve glioma or lesion tissue is prepared from the medical polyurethane, silicon rubber, latex or gelatin and the radioactive isotope 125I. Said carrier (gelatin) can be finally absorbed by human body.

Description

technical field [0001] The present invention relates to a kind of medical implant, relate to a kind of sodium iodide implant covered on NiTi alloy wire weaving or weaving support more precisely, implant human cavity or brain tissue, or use gelatin Inventions on foaming methods for manufacturing human absorbable sodium iodide implants, and methods for manufacturing medical sodium iodide implants. Background technique [0002] use of radioactive isotopes 125 I. 103 Pd, 32 P, etc. have a long history of treating human cancer and other diseases. It has been found that the cells that kill tumors or other disease-causing cells can be destroyed or killed by the directional radiation of radioisotopes. One of the most common forms of radiation therapy uses radioactive isotopes that radiate from a short distance as the treatment source, also known as brachytherapy. In the field of medical clinical use, radioactive isotopes are generally combined into a certain product through a su...
