Abstract
The present invention discloses a cervical carcinoma afterloading source applicator that scans and images through a CT machine for a cervical carcinoma afterloading therapy. The invention comprises a hollow source application pipe, one end of which is connected with an afterloading unit source application pipe, while the other end of the hollow source application pipe is a focus treatment end that is formed by oval inner pipes made by material with screening function; the center of the inner pipe is provided with a circular hole that is communicated with the source application pipe; the outside of the inner pipe is movably muff-coupled with a drum-shaped outer pipe made by CT compatible high molecular material. The present invention is capable of getting the three-dimensional image of a lesion position through CT scanning, thereby precisely confirming an estimated lesion scope and the normal tissues condition around the estimated lesion scope, which provides an image data basis for a precise individual radiotherapy.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments that is used for the cervical cancer after-loading therapy, especially a kind ofly can carry out source applicator after the cervical cancer of scanning imagery by the CT machine.
Background technology
The apparatus for wave-energy source that present treatment cervical cancer mainly adopts is the tee pipe apparatus for wave-energy source; it is classical cervical cancer after-loading therapy apparatus for wave-energy source; can obtain isodose curve and be just flat pyriform distribution; front and back dosage is lower than both sides; so just protected the bladder in the place ahead, uterus and the rectum at rear effectively, treatment back patient's rectal bladder damage reduces.But the tee pipe apparatus for wave-energy source uses difficulty bigger owing to three pipes are arranged and become 90 ° of angles mutually, and operation easier is big, and patient's misery is bigger in the operation.Can't obtain the CT image, can't accurately estimate extent of disease and with the relation of vitals on every side, can't formulate three-dimensional treatment plan, give accurate radiotherapy dosage, exist the treatment plan design complicated, displacement causes shortcomings such as dosage variation between pipe.
By the applicant's source applicator after the single tube type cervical cancer of application on March 1st, 2003; isodose curve is the same with the three tube type apparatus for wave-energy source; be just flat pyriform; can effectively protect rectal bladder; simple in structure; being a single tube, is this pipe directly to be put into diseased region treat in the treatment, and painful little, treatment plan is simple, dosage is accurate etc. the characteristics of easy and simple to handle, patient are arranged.But it is big to manage difficulty of processing, is not easy in practice to realize.Can't obtain three-dimensional image by CT scan, therefore can't correctly estimate the situation of extent of disease and normal structure, give the accurate radiotherapy dosage of individuation.This pipe can only carry out simple X plain film photography.
Therefore, how correct estimation extent of disease and with the relation of vitals on every side, obtain 3-D view so that accurately carry out radiotherapy, become the current problem that presses for solution.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art and a kind of apparatus for wave-energy source that can obtain 3-D view by CT scan is provided, this apparatus for wave-energy source is simple in structure, easy to use, and can correctly estimate extent of disease and normal surrounding tissue situation, penetrate therapeutic dose accurately view data is provided for putting after accurately.
The object of the present invention is achieved like this:
Can be used for source applicator behind the cervical cancer single hose of CT scan, it comprises the supply radiator duct road of a hollow, one end of pipeline is connected with the afterloading unit supply radiator duct, the other end is a focus treatment end, this treatment end is that pipe constitutes in oval that the function of shielding material makes by having, interior tube hub is provided with a circular hole, and this circular hole communicates with the supply radiator duct road, wherein also is socketed with a cylinder type outer tube that adopts the macromolecular material of CT compatibility to make outside interior pipe movably.
Wherein, location during for the ease of treatment, oval interior pipe and cylinder type outer tube can adopt the plug-in structure.
Operation principle of the present invention is as follows: earlier the cylinder type outer tube is put into diseased region during treatment, utilize the characteristic of cylinder type outer tube and CT compatibility, with apparatus for wave-energy source position in vivo, CT scan location, accurately estimate extent of disease and with the relation of vitals on every side, and a tree name this carry out apparatus for wave-energy source position, three-dimensional reconstruction image location, formulate the radiotherapy treatment planning of individuation on this basis, put into pipe then, connect and fix with the cylinder type outer tube, carry out precise radiotherapy again.
For the difference of invention and prior art effectively is described, tabulation compares several apparatus for wave-energy sourcees below:
As can be seen from the table, the present invention has following characteristics than prior art:
Because the present invention is a single tube structure, adopted oval-shaped interior pipe, guarantee to obtain the isodose curve the same and be just flat pyriform distribution with the tee pipe apparatus for wave-energy source; The cylinder type outer tube that the macromolecular material of while CT compatibility is made, becoming movable with interior pipe is connected, can put into diseased region earlier, obtain 3-D view by CT scan, thereby determine exactly to estimate extent of disease and normal surrounding tissue situation, accurately carrying out radiotherapy for individuation provides the view data foundation; The plug-in structure that is provided with between pipe and the cylinder type outer tube in oval can be located when interior pipe is put into exactly, guarantees the accuracy of therapentic part.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the cross-sectional view of focus treatment end of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail; but protection scope of the present invention has more than and is limited to these examples; such as the plug-in structure that is provided with between pipe in oval and the cylinder type outer tube; it can be other known movable connected mode; the macromolecular material of the CT compatibility that outer tube uses can be other function identical materials.
Embodiment: can be used for source applicator behind the cervical cancer single hose of CT scan, it comprises the supply radiator duct road 1 of a hollow, one end 6 of pipeline 1 is connected with the afterloading unit supply radiator duct, the other end is a focus treatment end 5, this treatment end 5 is that pipe 2 constitutes in oval that the function of shielding material makes by having, interior pipe 2 centers are provided with a circular hole 4, and this circular hole 4 communicates with supply radiator duct road 1, wherein also are connected with a cylinder type outer tube 3 that adopts the macromolecular material of CT compatibility to make outside interior pipe 2 movably.
Claims (2)
1. source applicator behind the cervical cancer single hose that can be used for CT scan, it comprises the supply radiator duct road of a hollow, one end of pipeline is connected with the afterloading unit supply radiator duct, the other end is a focus treatment end, this treatment end is that pipe constitutes in oval that the function of shielding material makes by having, interior tube hub is provided with a circular hole, and this circular hole communicates with the supply radiator duct road, it is characterized in that also being socketed with movably outside interior pipe a cylinder type outer tube that adopts the macromolecular material of CT compatibility to make.
