Abstract
Can conveniently take out after a kind of implantation, to the AT radion implantation device of patient; Comprising: the rubber implant; The rubber implant is a hollow pipe, the particle capsule is arranged at the top of rubber implant, the cavity that the built-in radion of particle capsule, particle capsule are positioned at the rubber implant is fixedlyed connected with rubber implant inwall, is positioned on the tube wall of top rubber implant of particle capsule to have flow-guiding mouth; The lower end of rubber implant has injection port; In this utility model, be provided with scale on the outer tube wall of rubber implant.
Description
Technical field
This utility model relates to a kind of X-ray therapy of tumor and uses instrument, relates in particular to a kind of radion implantation device that uses outside tumor tissues.
Background technology
Radiation treatment is as one of three big conventional meanses of oncotherapy, in the treatment malignant tumor, prolongs on patient's life and plays important effect.
Because the current diagnosis technology limitation still can not be accomplished early diagnosis fully, when going to a doctor, many patients just entered the middle and advanced stage of cancer, lost the chance of surgical radical treatment.Therefore adopt radiotherapy just to become one of requisite treatment means clinically.There is 70% tumor patient need carry out radiotherapy clinically approximately in the different phase of its treatment.
Because traditional outer X-ray therapy all can't be kept apart normal structure and tumor tissues; therefore in therapeutic process, can cause damage to normal tissue, organ; also can tumor can not be effected a radical cure completely owing to giving less than enough therapeutic doses for the protection normal structure.
In recent years, the man-made isotope that many half-life are short, irradiation distance is near, radiant is low is manufactured in succession to come out and is applied to clinical, as iodine-125, gold-198, palladium-103 etc., make the imagination of advancing the radiation treatment of Wicresoft at the tumor tissues part become possibility, plant closely between radioactive particle tissue that to treat the tumor technology be exactly one of them.This technology is to adopt low-yield, more short-decayed radioactive sealed source microgranule, through Computerized three-dimensional treatment planning systems accurate Calculation, adopts special equipment that it is implanted in the tumor body, is subjected to invade tissues and subclinical kitchen range with interventional method or in art.Lasting decay by mini-radioactive resource; tumor tissues is carried out the persistence low dose exposure; can be in limit ground protection normal structure on every side; prevent the damage of responsive organ; therapeutic domain and treatment indication have been enlarged; controlled simultaneously that the tumor cell that is in resting stage is activated and the process that doubles, the deficiency that the peripheral damage that has remedied external exposure is big, oncocyte resting stage can't be effectively eliminated in the discontinuity irradiation has played positive effect to preventing the diffusion of postoperative local recurrence and tumor.But, owing to adopt the implantation instrument of metal shell to implant, big to patient trauma, and can't take out after implanting, body is easy to generate foreign body reaction.
Summary of the invention
The purpose of this utility model can conveniently be taken out after providing a kind of implantation, to the AT radion implantation device of patient.
For achieving the above object, the technical scheme that this utility model adopted is: a kind of radion implantation device, comprising: the rubber implant; Its characteristics are: the rubber implant is a hollow pipe, the particle capsule is arranged at the top of rubber implant, the cavity that the built-in radion of particle capsule, particle capsule are positioned at the rubber implant is fixedlyed connected with rubber implant inwall, is positioned on the tube wall of top rubber implant of particle capsule to have flow-guiding mouth; The lower end of rubber implant has injection port.
The utility model has the advantages that: because the built-in radion of particle capsule in this utility model, can be during use with the rubber implant along the pipeline of body such as food meatus, trachea, urethra tube, insert near tumor locus, carry out the radion radiotherapy, the rubber implant can be extracted out by the time it's the half-life has been past radion.Therefore use this utility model to do tumour radiotherapy, particle can conveniently take out after implanting, and patient is not had wound.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an another kind of structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is further described:
A kind of radion implantation device, as shown in Figure 1, 2, comprising: rubber implant 1; Its characteristics are: rubber implant 1 is hollow pipe, particle capsule 2 is arranged at the top of rubber implant 1, particle capsule 2 built-in radions, the cavity that particle capsule 2 is positioned at rubber implant 1 is fixedlyed connected with rubber implant 1 inwall, is positioned on the tube wall of top rubber implant 1 of particle capsule 2 to have flow-guiding mouth 3; The lower end of rubber implant 1 has injection port 4; In this utility model, be provided with scale 5 on the outer tube wall of rubber implant 1.
With the esophageal tumor is example, earlier esophagus is inserted by nasal cavity or oral cavity in upper end of the present utility model, is provided with radion in the particle capsule that scale can make rubber implant upper end near the tumor locus of esophagus by the outer tube wall of watching the rubber implant; The radiation distance of radion is 1 centimetre, and the half-life is 57.8 days; The lower end of rubber implant is stayed external, can inject liquid from its injection port and draw food or energy, enters stomach by flow-guiding mouth.Radion in this utility model can be extracted the rubber implant out through after the half-life in esophagus.
The beneficial effects of the utility model are: when the utility model is implanted human body is not had wound, taking-up time side Just, radion is recyclable, protection of the environment.
