Abstract
The utility model provides a single-tube cervical cancer after-loading source applicator, which overcomes the disadvantages of high complication by traditional single uterine cavity tube curing, big operation difficulty of three-tube source applicator and big suffering of patients, the utility model is characterized in that the lesions of the single-tube source applicator adopts an inner tube, an external tube and a reside pipe structure for radioactive source, wherein, the external diameter of the inner tube is elliptical and high-density alloyed while the inner diameter is round, the inner diameter of the external tube is elliptical and low-density alloyed while the external diameter is round. The source applicator adopting the structure has the advantages of convenient operation of traditional single uterine cavity tube, less suffering of patients, reasonable dosage distributing of three-tube source applicator, more particularly, the utility model is suitable to after-loading cure for cervical cancer.
Description
Affiliated technical field
This utility model relates to source applicator after a kind of medical apparatus and instruments that is used for the cervical cancer after-loading therapy, the especially cervical cancer.
Background technology
In the cervical cancer after-loading therapy, be just flat pyriform distribution at present in order to obtain isodose curve, general adopt the tee pipe apparatus for wave-energy source, but the tee pipe apparatus for wave-energy source is owing to have three pipes and mutually at an angle of 90, patient's misery is bigger in the operation, use difficulty also big, the while treatment plan is more complicated also.Adopt traditional single uterine cavity pipe under a few cases, though this uterine cavity pipe is easy to operate, patient's misery is little, the treatment plan simplicity of design, but because structure is simple tubular, make the isodose curve of the focus amount of being subjected to be positive pyriform and distribute, cause in the treatment the vesicorectal amount of being subjected to too high, make the patient higher in treatment infectious-related complication incidence rate.
The utility model content
The technical problems to be solved in the utility model provides a kind of apparatus for wave-energy source, and it promptly is that single tube and result of use can equally with the tee pipe apparatus for wave-energy source obtain isodose curve and be just flat pyriform and distribute.
In order to achieve the above object, this utility model is realized like this: traditional single uterine cavity pipe is transformed, this uterine cavity Guan Youyi root stage casing has the bending stainless steel tube of two place's circular arcs to constitute, the stainless steel tube internal diameter is the circular hole passage, one end of this stainless steel tube is connected with the afterloading unit supply radiator duct, and the other end is a focus treatment end; At one section resident pipeline that is used for radioactive source that interior pipe and outer tube constituted that is assembled together of focus treatment end welding, interior effective heavy alloy is made, and its external diameter is oval, and internal diameter is that circular hole communicates with the stainless steel tube internal diameter; Outer effective low density material is made, and its internal diameter is the ellipse identical with interior external diameter of pipe, and external diameter is circular.
Adopt the single tube apparatus for wave-energy source advantage of said structure to be: simple in structure; easy and simple to handle; the patient suffering is little; simultaneously owing to structurally adopted additional ray barrier technique; make that this utility model is the same with the tee pipe apparatus for wave-energy source to reach the purpose of obtaining just flat pyriform dose distribution; protect bladder and rectum effectively, reduced the generation of treatment infectious-related complication.
Description of drawings
Below in conjunction with drawings and embodiments this utility model is implemented to be described in further detail:
Fig. 1 is this utility model external structure.
Fig. 2 is the resident cross-section of pipeline figure of this utility model radioactive source.
Among the figure: 1, stainless steel tube, 2, the resident pipeline of radioactive source, 3, afterloading unit supply radiator duct link, 4, interior pipe, 5, outer tube, 6, circular hole, 7, weld.
The specific embodiment
This utility model external structure as shown in Figure 1, there is the bending stainless steel tube (1) of two place's circular arcs to constitute by a stage casing, stainless steel tube (1) internal diameter is the circular hole passage, one end of stainless steel tube (1) is an afterloading unit supply radiator duct link (3), the other end is a focus treatment end, at one section resident pipeline of radioactive source (2) that is made of interior pipe (4) and outer tube (5) of treatment end weld (7) welding.As shown in Figure 2, interior pipe (4) is used heavy alloy, makes as tungsten alloy etc., external diameter is oval, and internal diameter is that circular hole (6) communicates with stainless steel tube (1) internal diameter, and its way is, after can adopting casting or round steel to be processed into oval external diameter, centre drill circular hole (6) communicates with the stainless steel tube internal diameter.In Fig. 2, the available low density material of outer tube (5) is made, as organic glass etc.The internal diameter of outer tube (5) is and the identical ellipse of interior pipe (4) external diameter that external diameter is circular.Interior pipe (4) can adopt the bonding way assembling with outer tube (5), promptly behind pipe (4) surface adhesion low density material formation outer tube (5), polishes smooth outer tube (5) appearance circular in ready-made.
Claims (1)
1, source applicator after a kind of single hose cervical cancer has the bending stainless steel tube of two place's circular arcs to constitute by a stage casing, and the stainless steel tube internal diameter is the circular hole passage, and an end of this stainless steel tube is connected with the afterloading unit supply radiator duct, and the other end is a focus treatment end; It is characterized in that: at one section resident pipeline that is used for radioactive source that interior pipe and outer tube constituted that is assembled together of treatment end welding, interior effective heavy alloy is made, and its external diameter is oval, and internal diameter is that circular hole communicates with the stainless steel tube internal diameter; Outer effective low density material is made, and its internal diameter is the ellipse identical with interior external diameter of pipe, and external diameter is circular.
