Abstract
The utility model provides an implantable iodine-125 radioactive seed strip which is characterized by comprising a medical catheter, wherein the two ends of the medical catheter are sealed, and iodine-125 radioactive seeds are placed inside the medical catheter. The iodine-125 radioactive seeds include a titanium shell and a silver rod which is arranged inside the titanium shell and absorbs iodine-125 radioactive nuclide on the surface. The implantable iodine-125 radioactive seed strip has less implanting damage, and can be implanted into a cavity only by one puncture.
Description
Technical field
This utility model relates to a kind of implantation property iodine-125 radioactive seed source bar, is used to treat malignant entity tumor, belongs to technical field of medical instruments.
Background technology
Implant iodine-125 radioactive seed source treatment malignant entity tumor technology between tissue and extensively carry out clinically, and obtained good curative effect.Implant the iodine-125 radioactive seed source between traditional tissue and have following shortcoming:
1, need multiple spot, repeatedly implant for reaching prescribed dose, penetration damage is bigger;
2, be difficult to guarantee that the iodine-125 radioactive seed source of being implanted is evenly distributed at the target intralesional;
3, the iodine-125 radioactive seed source of being implanted is shifted, and causes the radiation damage in non-focus zone.
Summary of the invention
The purpose of this utility model provides a kind of implantation property iodine-125 radioactive seed source bar, utilizes intracavity to implant the ionizing radiation that iodine-125 radioactive seed source bar is produced, and the pathological changes that causes portal vein, postcava and malignant biliary obstruction is carried out brachytherapy.
In order to achieve the above object, this utility model provides a kind of implantation property iodine-125 radioactive seed source bar, it is characterized in that, comprises medical catheter, described medical catheter closed at both ends, and inside is provided with the iodine-125 radioactive seed source.
The silver rod that described iodine-125 radioactive seed source comprises the titanium shell and is located at the surface adsorption iodine-125 radionuclide in the titanium shell.
Preferably, the length of the silver rod of described surface adsorption iodine-125 radionuclide is 3～4mm.
Preferably, the length of described titanium shell is that 4～5mm, diameter are 0.5～1mm.
The utility model has the advantages that:
1, the implantation damage is little, only needs one-time puncture can accomplish intracavity and implants iodine-125 radioactive seed source bar;
2, the radiation that the iodine-125 radioactive seed source of having guaranteed to implant is produced is evenly distributed at the target intralesional;
3, the iodine-125 radioactive seed source bar of being implanted is closed in the plastic catheter, and conduit is fixed on support again
And between portal vein, cavity of resorption or the biliary tract wall, thereby eliminated the displacement of iodine-125 radioactive seed source, and will descend greatly the radiation damage in non-focus zone;
4, utilize intracavity to implant the ionizing radiation that iodine-125 radioactive seed source bar is produced; The radiotherapy that the change disease that causes portal vein, postcava and malignant biliary obstruction is continued; Significant prolongation the unobstructed time of above-mentioned tube chamber, further reach the target that prolongs patient life cycle, improves the quality of living.
Description of drawings
Fig. 1 is the sketch map of iodine-125 radioactive seed source;
Fig. 2 is the sketch map of iodine-125 radioactive seed source bar.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is described further.
Embodiment
As shown in Figure 2, be the sketch map of iodine-125 radioactive seed source bar, described iodine-125 radioactive seed source bar comprises medical catheter 4, inside is provided with iodine-125 radioactive seed source 1.The external diameter of medical catheter 4 is that the internal diameter of 1.35mm, medical catheter 4 is 1.0mm, and iodine-125 radioactive seed source 1 is packed into behind the medical catheter 4, and two ends are sealed with flame, and forming length is the iodine-125 radioactive seed source bar of L, implants malignant tumor then and blocks the place.As shown in Figure 1, be the sketch map of iodine-125 radioactive seed source, the silver rod 2 that described iodine-125 radioactive seed source 1 comprises titanium shell 3 and is located at the surface adsorption iodine-125 radionuclide in the titanium shell 3.The length of the silver rod 2 of described surface adsorption iodine-125 radionuclide is 3.25mm.The length of described titanium shell 3 is that 4.5mm, diameter are 0.8mm.
During use; 2 grades of smooth branches of puncture liver inside door beniol under us guide; Row portal vein radiography; Measure the quantity that malignant tumor is blocked segment length, confirmed the iodine-125 radioactive seed source 1 of required implantation, iodine-125 radioactive seed source 1 is packed in aseptic, the transparent medical catheter 4, one-time puncture is accomplished intracavity and is implanted iodine-125 radioactive seed source bar.
