Description
Technical field
The invention belongs to medical instruments field, and in particular to a kind of radioactive particle branch for cavity tumour Inner irradiation
Frame.
Background technology
The problem of cavity cancer maximum is exactly to block, when that can not use operation or other means remove tumour, using radiotherapy energy
Effectively suppress the growth of tumour, but extracorporeal irradiation has the shortcomings of irradiation is discontinuous, radiological dose is big.At present, Medical rack has been
It is narrow through being widely used in clinical treatment cavity, common Medical rack uniquely rely on the support force of support in itself strut it is narrow
Cavity, certain mitigation is served, but as the probability of the growth ISR of tumour is larger.
In recent years, substantial amounts of clinical treatment proves et al. Ke radioactive particle such as125I etc. is to cancers such as cancer of the esophagus, cancer of bile ducts
Disease patient reaches good therapeutic effect, and over the course for the treatment of to the damage very little of the other tissues of patient.ZL03221951.2
Inner irradiation support is disclosed, radion is packed into the particle filling pipe being bundled on support by it, the advantages of the invention
It is:(1) particle filling pipe is provided with radion support, particle can be implanted in vivo with support.(2) radioactive source
Can irradiation tumour closely for a long time, to suppress its growth.Its shortcoming is:(1) for single support, particle filling pipe
Position is fixed, number is limited, and the lesions position of patient is different, size of tumor and different, the radioactivity grain of required placement
The position and number of son also differ.(2) particle filling pipe position protrudes, and local compression is heavier, easily causes local damage, goes out
Blood.(3) Nitinol filling pipe can mask a part of activity, the irradiation intensity of tumour can be weakened, so as to influence to treat
Effect.(4) preparation technology is complicated.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, there is provided a kind of simple in construction, simple for production, implantation is convenient,
It is not easy a kind of radioactive particle support for cavity tumour Inner irradiation for causing local damage.
Technical scheme is summarized as follows:
A kind of radioactive particle support for cavity tumour Inner irradiation, including it is provided with along long axis direction the alloy of opening
Pipe silk 3 weaves the rack body 1 and radioactive particle 2 formed, and radioactive particle 2 is arranged in the alloy tube wire 3 of opening.
The shape of rack body 1 is selected from:Cylindrical shape, it is tubaeform, middle in cylinder both ends flare, spherical or mushroom
Shape.
The internal diameter of the alloy tube wire 3 of opening is 0.2~2mm;It is corresponding, the external diameter of radioactive particle 2 for 0.2~
2mm and length are 0.2~20mm, or the external diameter of radioactive particle 2 is slightly less than the internal diameter of alloy tube wire 3.
Radioactive particle is selected from:I-125 seeds, the particle of palladium -103, the particle of gold -198, cesium-131 particle, ytterbium -169
Son, Yttrium-90 particle and the particle of phosphorus -32.
The opening chord length of the alloy tube wire 3 of opening is the 1/4~1 of the alloy tube wire internal diameter of opening.
The material of the alloy tube wire 3 of opening is selected from:Nitinol, copper series alloy or iron-based alloy with Memorability.
The present invention is simple in construction, simple for production, easy to use, different size and model can be prepared into, suitable for difference
Tumor size, the conformal therapy of cavity tumour is realized, so as to improve curative effect, lower the damage of normal tissue.Radioactive particle
The diverse location of the alloy tube wire of opening is stuck in or be bonded in securely, radioactive particle is reduced and comes off probability.Reduce conjunction
Golden Guan Sibi improves radioactivity utilization ratio, reduces cost to the radiation shield of radioactive particle.
