Abstract
This utility model belongs to medical instruments field, is specifically related to a kind of radiotherapy applicating device for curing for the treatment of rhino tumor.The beneficial effect that this utility model has is: fixed between apparatus for wave-energy source and nose, can not arbitrarily movement, in operation is carried out, prevent operation deviation, radioactive source can control mobile in supply radiator duct by therapy apparatus, and under the control action of air bag, radioactive source can be partial to the side of tumor, make it more near tumor area, strengthen therapeutic effect, and normal tissue cell is away from radioactive source, can not because of excessive radiation damaged, perform the operation safer.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of radiotherapy applicating device for curing for the treatment of rhino tumor.
Background technology
One of modal benign tumor of nasal inverted papilloma (NIP) Shi Bi section, its pathological characters is epithelial tissue exuberant, epithelium agglomerate upwards in subcutaneous interstitial in a tubular form or finger-like deeply, thus the mode of appearance of morphogenesis characters.Sometimes tumor by local is that polypoid changes, therefore is often misdiagnosed as nasal polyp.
Often tumor originates is in local for the individuality of First episode, and as germinal center, this hair growth promoting position can be positioned at nasal cavity, also can be positioned at nasal sinuses, and the position order sending out well nasal sinuses is generally: sieve hole, maxillary sinus, sphenoid sinus, sinus frontalis.
For the nasal inverted papilloma of morbidity in nasal cavity position, generally take tumor resection under nasal endoscopes, along with popularizing of brachytherapy technology, present radiotherapy in the treatment nasal inverted papilloma has started to occur, adopts apparatus for wave-energy source to be positioned over tumor locus, and the radioactive source in apparatus for wave-energy source is connected with therapy apparatus by conduction steel wire, radioactive source is directly at tumor locus radiotherapy, lower than traditional operative treatment relapse rate, and painful little in operation process, and tumor cell kill is high.But apparatus for wave-energy source is when the nasal inverted papilloma treatment for nasal cavity position at present, often there is following typical problem, one is fixing not firm, loosen once appearance and just there will be comparatively major operation deviation, two is that source positions is not easy to change, and can not be positioned at tumor accurately and suffer from district.
Utility model content
According to above the deficiencies in the prior art, this utility model provides a kind of radiotherapy applicating device for curing for the treatment of rhino tumor, has fixed, accurate positioning, the feature that radiotherapy is safer.
A kind of radiotherapy applicating device for curing for the treatment of rhino tumor described in the utility model, it is characterized in that: comprise the matrix for holding radioactive source, described matrix comprise two symmetric designs round plastic sleeve pipe and between connection strap, matrix both sides are provided with nose clip, be provided with one end and close in described plastic bushing, the cavity of other end opening, supply radiator duct is provided with in described cavity, supply radiator duct is thin wall hollow pipe, and the one end pointing to cavity is closed, and the other end is connected with therapy apparatus;
Described plastic bushing outer wall is along the circumferential direction evenly provided with 2 ~ 4 independently air bags, and each air bag is all plugged with balloon catheter, and the balloon catheter other end is connected with external inflation source, and each balloon catheter end is equipped with Valve controlling.
Wherein, preferred version is as follows:
Nose clip is elastoplast body, can directly withhold on nose, easy to use.
Inside nose clip, laminating is provided with foam-rubber cushion, and foam-rubber cushion can alleviate the pressure between nose clip and nose, in order to avoid cause the discomfort of patient for a long time.
Described plastic bushing outer wall is along the circumferential direction evenly provided with 3 independently air bags.
This utility model in use, according to the disease condition of patient, select to insert supply radiator duct in arbitrary round plastic sleeve pipe wherein, if two nasal cavities are all ill, then need all to insert supply radiator duct, after apparatus for wave-energy source is in place, the patient carrying apparatus for wave-energy source is carried out CT scan, in the air bag away from tumor side, be filled with proper amount of gas makes supply radiator duct center offset to tumor direction, check CT confirms that supply radiator duct center is fixing after being in appropriate location, to reach the object improving tumor exposure dosage and reduce normal nasal cavity tissue cell exposure dosage.Then be connected with therapy apparatus by supply radiator duct, start therapy apparatus, conduction steel wire stretches out and enters in supply radiator duct from therapy apparatus, and the position of computer controlled automatic radioactive source and residence time, carry out plesioradiotherapy.
The beneficial effect that this utility model has is: fixed between apparatus for wave-energy source and nose, can not arbitrarily movement, in operation is carried out, prevent operation deviation, radioactive source can control mobile in supply radiator duct by therapy apparatus, and under the control action of air bag, radioactive source can be partial to the side of tumor, make it more near tumor area, strengthen therapeutic effect, and normal tissue cell is away from radioactive source, can not because of excessive radiation damaged, perform the operation safer.
