Abstract
The utility model provides a back-installed source applicator of an esophageal cancer, which comprises a source applicator body. Metal powder is coated on a head of the front end of the source applicator body, a back-installed pipeline is arranged in the center of the source applicator body, a pair of water bags are symmetrically arranged at the front end of the outer wall of the source applicator body, two water injecting pipelines which are parallel to the back-installed pipeline are arranged inside the tube wall of the source applicator body, one ends of the two water injecting pipelines are respectively communicated with the two water bags, and water injecting openings at the other ends of the two water injecting pipelines are arranged on an end opening of the tail end of the source applicator body. The back-installed source applicator of the esophageal cancer is capable of completing positioning and treatment at a time, decreasing operating procedures and reducing damage to a patient. The pair of the water bags is symmetrically arranged at the front end of the outer wall of the source applicator body and dilation of the water bags has the functions that firstly, the source applicator can be internally fixed; and secondly, an esophageal lesion site can be dilated and irradiation dose to surrounding normal tissues can be reduced so as to prevent stenosis of the esophageal lesion site at a later stage.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, source applicator after especially a kind of esophageal carcinoma.
Background technology
The esophageal carcinoma is China's common malignancy, during prescription on individual diagnosis only 20% patient can make radical surgery (the 5 years survival rates of performing the operation are 20%～25%), 80% patient is a middle and advanced stage, can't perform the operation, the main radiotherapy that relies on, the radiotherapy of the esophageal carcinoma modes that adopt afterloading radiotherapy in the external radiotherapy combined esophageal lumen at present more.
Intracavitary radiotherapy can significantly improve the late result of patient with esophageal carcinoma, and the patient will gulp down barium earlier during concrete operations, under the X line perspective determining the size of tumor, position and block degree.Then use the common stomach tube that is added with plumbous seal wire in the tube chamber to be inserted under the esophagus diseased region analog machine through nasopharynx and position and formulate radiotherapy planning from the patient nostril, then plumbous seal wire is transferred to, the back source applicator is introduced esophagus canceration position along the stomach tube tract, apparatus for wave-energy source one end is in stomach tube, the other end is connected with afterloading unit, according to the plan of formulating by the CCRT process.This method operating procedure is many, finds in the enforcement that it has two big shortcomings: the one, apparatus for wave-energy source and cover stomach tube outside thereof in esophagus, be difficult for fixedly causing each time treat in the distance of tumor and radioactive source can not be consistent calculating tumor exposure dose inaccuracy; The 2nd, to be invaded esophageal tissue and inviolacy esophageal tissue in the treatment and accepted identical exposure dose, patient's radiation esophagitis symptomatic reaction is obvious, even perforation of esophagus occurs and cause the patient to be difficult to tolerate and can not finish radiotherapy according to plan.The current technical problem that presses for solution clinically is for patient with esophageal carcinoma provides a kind of easy and simple to handle, the radiotherapy apparatus that therapeutic effect is good.
Summary of the invention
The purpose of this utility model provides source applicator after a kind of esophageal carcinoma, and location and treatment are once finished, and has reduced the generation of complication such as radiation esophagitis, and the step that can effectively simplify the operation reduces the injury that in the complicated operating process patient is brought.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: source applicator after the esophageal carcinoma, comprise the apparatus for wave-energy source body, it is characterized in that: the end of described apparatus for wave-energy source body front end scribbles metal powder, the center of apparatus for wave-energy source body is provided with the afterloading tube road, the front end of apparatus for wave-energy source body outer wall is arranged with a pair of water pocket, the tube wall inside of apparatus for wave-energy source body has two filling pipes that parallel with the afterloading tube road, article two, the filling pipe end communicates with two water pockets respectively, and the water filling port of the other end is located on the port of apparatus for wave-energy source body tail end.
To improvement of the technical scheme: the long 800mm of described apparatus for wave-energy source body, diameter are 8mm, and its tube wall surface is provided with scale, the afterloading tube road that the apparatus for wave-energy source center is set, its diameter is 2.2mm, and the termination of apparatus for wave-energy source body front end is ellipticity, and the port is provided with circular arc chamfering.
To further improvement in the technical proposal: the length 250mm of described two water pockets, heap(ed) capacity are 120ml, and hold 1/2 of apparatus for wave-energy source body respectively, and two inlet channel diameters of water pocket are 2.5mm.
Beneficial effect:
Use source applicator after the esophageal carcinoma described in the utility model, the end of apparatus for wave-energy source body front end scribbles metal powder, the center of apparatus for wave-energy source body is provided with the afterloading tube road, the apparatus for wave-energy source body surface has scale, so just location and treatment once can be finished, reduced operating procedure, alleviated damage the patient; The front end of apparatus for wave-energy source body outer wall is arranged with a pair of water pocket, water balloon dilator one is the effect that can play an internal fixation to apparatus for wave-energy source, the 2nd, expansible esophagus diseased region, and can reduce exposure dose to normal surrounding tissue, it is narrow to prevent that esophageal carcinoma pathological changes district's later stage from occurring; And can inject 4 ℃ of contrast agent in the water pocket when treatment, such 4 ℃ of cryogenic conditions that contrast agent brought can make the radioresistance of esophagus normal mucosa be improved, and can suitably strengthen radiotherapy dosage, improve the local control rate of esophagus; Described water pocket holds apparatus for wave-energy source 1/2 respectively, when esophagus one side generation pathological changes, can guarantee the radiological dose of pathological changes side esophagus, protects the not esophageal wall of pathological changes side, has reduced the generation of complication such as radiation esophagitis.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Source applicator after this utility model esophageal carcinoma as shown in Figure 1,1 place, termination of described apparatus for wave-energy source body front end scribbles metal powder, the center of apparatus for wave-energy source body is provided with afterloading tube road 2, the front end of apparatus for wave-energy source body outer wall is arranged with a pair of water pocket 3,4, two water pockets 3,4 length 250mm, heap(ed) capacity is 120ml, and hold 1/2 of apparatus for wave-energy source body respectively, the tube wall inside of apparatus for wave-energy source body has two filling pipes 5 that parallel with the afterloading tube road, 6, article two, filling pipe one end respectively with two water pockets 3,4 communicate, the water filling port 7 of the other end, 8 are located on the port of apparatus for wave-energy source body tail end, two inlet channels 5,6 diameters are 2.5mm.The long 800mm of described apparatus for wave-energy source body, diameter are 8mm, and its tube wall surface is provided with scale 9, and the afterloading tube road that the apparatus for wave-energy source center is set, its diameter are 2.2mm, and the termination of apparatus for wave-energy source body front end is ellipticity, and the port is provided with circular arc chamfering.
