Abstract
The utility model discloses a kind of plant type single tube applicating device, comprise single tube applicating device, single tube applicating device comprises open end and focus treatment end, open end connects afterloading unit supply radiator duct, focus treatment end is formed by having pipe in ellipse that function of shielding material makes, and interior tube hub is provided with circular hole; Focus treatment end is through plant template, and plant template is provided with large treatment hole and multiple plant pin hole, and plant pin hole distributes according to the cloth source rule of Paris system in plant template, multiple plant pin that plant pin hole is planted.The utility model is according to the structure of human body; dexterously radioactive source is put into inside tumor; radiation dose distribution is radiated at inside tumor equably; available protecting normal surrounding tissue; avoid dosage hot-zone and dosage cold-zone; and transplanting pin position is in the tissue fixed by template, does not move with displacement body, be conducive to the precision and the accuracy that improve treatment.
Description
Technical field
The utility model belongs to a kind of medicine equipment, is specifically related to a kind of plant type single tube applicating device.
Background technology
Plesioradiotherapy is radiocurable a kind of form, by radioactive source be positioned over need treatment part interior or near.Plesioradiotherapy is widely used in cervical carcinoma, prostate cancer, breast cancer, and the treatment of cutaneum carcinoma, is applicable to the oncotherapy at other positions many too.Brachytherapy can carry out separately or with other therapies, as operation, external exposure radiation and chemotherapy combine.
At present, the afterloading unit used in hospital carries out cervical carcinoma intracavitary therapy, and many employings three pipe applicating devices, uterine cavity pipe, vaginal canal or vaginal ball are given and most of corpus uteri, uterine neck, fornix and vaginal dosage.Because three pipe applicating devices are managed owing to there being three and becoming mutually 90 ° of angles, complex structure, volume is large, and therefore operation easier is large, and in operation, the misery of patient is larger, and therapentic part is only confined to three pipe near zones, cannot go deep into inside tumor.
Meanwhile, the growth of tumour is Multiple Shape, and tumour locally may to be formed at outer other of uterine neck, and three traditional pipes cannot effective irradiation tumor area, causes tumour to control bad.
Utility model content
The purpose of this utility model is to provide a kind of plant type single tube applicating device, radiological dose can be transported to the position that all tumours exist, and improves result for the treatment of.
For achieving the above object, technical solution adopted in the utility model is:
Comprise single tube applicating device, single tube applicating device comprises open end and focus treatment end, and open end connects afterloading unit supply radiator duct, and focus treatment end is formed by having pipe in ellipse that function of shielding material makes, and interior tube hub is provided with circular hole; Focus treatment end is through plant template, and plant template is provided with large treatment hole and multiple plant pin hole, and plant pin hole distributes according to the cloth source rule of Paris system in plant template, multiple plant pin that plant pin hole is planted.
Preferably, plant template be poly (methyl methacrylate) plate.
The beneficial effect that this plant type single tube applicating device produces is:
By single tube applicating device and plant pin, radiological dose is delivered to diseased region, radiation dose distribution is even, more avoids dosage hot-zone and dosage cold-zone, gives tumour more high dose.Protection normal structure.Plant pin position in the tissue template of being planted is fixed, and does not move with displacement body, is conducive to the precision and stability for the treatment of.Effectively can replace existing traditional three pipe applicating devices, change traditional therapeutic device, bring the innovation in apparatus mode, also bring patient convenient, improve result for the treatment of.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, Fig. 2, Fig. 1, Figure 2 shows that a kind of type single tube of planting of the present utility model executes the structural representation of an embodiment in source.In the present embodiment, plant type applicating device comprises single tube applicating device 1, and single tube applicating device 1 comprises open end 4 and focus treatment end 5, and open end 4 connects afterloading unit supply radiator duct, focus treatment end 5 is formed by having pipe in ellipse that function of shielding material makes, and interior tube hub is provided with circular hole, focus treatment end 5 is through plant template 2, plant template 2 is provided with large treatment hole 7 and multiple plant pin hole 8, focus treatment end 5 inserts focal zone 4 through large treatment hole 7, plant pin hole 8 distributes according to the cloth source rule of Paris system in plant template, plant pin hole 8 to be planted multiple plant pin 3, plant pin 3 thrusts focal zone 4, by plant pin 3, radiological dose is delivered to diseased region, radiation dose distribution is even simultaneously, avoid dosage hot-zone and dosage cold-zone, and plant pin 3 position is in the tissue fixed, do not move with displacement body, be conducive to the precision and stability for the treatment of.
With reference to figure 1, Fig. 2, in an embodiment of the present utility model, plant template 2 is poly (methyl methacrylate) plate, better can observe diseased region.
When using this applicating device to treat, first by patient's lithotomy position, uterine cavity is probeed into after routine disinfection, place single tube applicating device inner to uterus, subsequently plant template 2 is put into fornix vaginae, according to the situation of tumour, select different apertures, put into the degree of depth that plant pin 3 needs to tumor locus.Clog vagina with gauze subsequently, according to CT picture of patient, carry out successive treatment.
Fig. 3 is three pipe applicating device dose distribution map; Fig. 4 is the dose distribution map of a kind of type single tube applicating device of planting of the present utility model.Can find out, compared with Fig. 3, the dosage distribution of Fig. 4 is more extensive, and uniformity is better.
Above-mentioned embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
