A kind of efficient wheel shaft type gun shaped radion implanting device and its working methodTechnical field
The invention belongs to medical instruments field, in particular to a kind of efficient wheel shaft type gun shaped radion implanting device.ThisInvention further relates to a kind of working method of efficient wheel shaft type gun shaped radion implanting device.
Background technique
Three big conventional means (operation, chemotherapy, radiotherapy) one of of the radiation treatment as oncotherapy, are controllingVery important effect is played in treatment malignant tumour, extension patient vitals.
Due to the limitation of current diagnosis technology, it cannot still accomplish early detection, early diagnosis completely, when many patient assessmentsThe middle and advanced stage for just coming into cancer loses the chance of surgical radical treatment.Therefore just become using radiotherapy and clinically must notOne of the treatment means that can lack.Clinically the different phase there are about 70% tumor patient in its treatment needs to carry out radiotherapy.
Since traditional outer radiotherapy can not keep apart normal tissue and tumor tissues, in therapeutic processIn normal tissue, organ can be damaged, also due to making for protection normal tissue and to less than enough therapeutic dosesTumour cannot be eradicated thoroughly.
In recent years, the man-made isotope that many half-life shorts, irradiation distance are close, radiant is low is manufactured and applies in successionIn clinic, such as 125I, 198Au, 103Pa, so that locally carrying out being thought of as minimally invasive radiation treatment for tumor tissuesTo be possible, short distance transplanting treatment tumour technology is exactly one of them between radioactive particle tissue.The technology be using low energy,Compared with the radioactive sealed source particle of short-half-life, accurately calculated by Computerized three-dimensional treatment planning systems, with interventional method orIt is implanted into knurl in art using special equipment, by infiltration tissue and subclinical stove.Pass through continuing for mini-radioactive resourceDecay carries out duration low dose exposure to tumor tissues, can protect the normal tissue of surrounding to the maximum extent, prevent sensitivityThe damage of organ, expand therapeutic domain and treatment indication, while control the tumour cell in resting stage be activated andThe process of multiplication, the deficiency that the peripheral damage for compensating for external exposure is big, discontinuity irradiation can not effectively eliminate resting stage oncocyte,Positive effect is played to preventing Local Recurrence and tumour from spreading.Since the implantation instrument using metal shell passes through nowIt is implanted into for minimal invasive techniques, it is small to patient trauma, while effectively preventing radiation of the operating process to performer.
Currently used implantation instrument, has the drawback that
1, supplement radioactive source is inconvenient, and a rotating disc type implanting device can only generally load 20-40 radioactive sources, and a patient oneSecondary treatment is frequently necessary to plant particle tens of or even up to a hundred, and it is neither square that the implanting device of integral type supplements loading radioactive source in artJust also dangerous.
2, rotating disc type storage implantation warehouse product is larger, and certain volume range is distributed in body foci, so existing accordinglyIt generally requires to be inserted into more middle empty needles simultaneously within the scope of this, large volume of implantation storehouse is easy to hollow with these when operating in this wayNeedle collides, it could even be possible to touching the middle empty needle being inserted into, leads to the danger for puncturing human body vitals or blood vessel, soThe work difficulty of operating theatre staff is very big.
3, it should extract to constantly convey radioactive source and push pin completely, again the movement meeting of the turntable in rotation storage implantation storehouseIncrease operating theatre staff's operating burden.
4, the larger and weight weight of storage implantation warehouse product of rotating disc type implanting device, operation are painstaking.
5, the implantation of radion needs to be implanted into the withdraw of the needle, and matching between middle empty needle and implanting device is combined into taper and matchesIt closes, only frictionally is connected and fixed, such as the misoperation heart during the withdraw of the needle, it is easy to separate middle empty needle with implanting device.
