Abstract
The utility model discloses an after-loading source applicator used for the after loading therapy of the cervical cancer and processing scanning imaging through a CT machine, comprising a hollow source application channel whose one end is connected with an after-loading machine source application tube and the other end is the focus treatment end; the focus treatment end is constructed by an ellipse inner tube made of shielding material; a circular hole is arranged at the center of the inner tube; the circular hole is communicated with the source application channel; a cylindrical outer tube made of polymer material which is compatible with the CT is sleeved outside the inner tube movably; the utility model can obtain the 3D image of the focus part through the scanning of the CT so that the focus range and the state of the periphery tissues are accurately determined and estimated; and the image data basis is provided for the individual accurate radiation therapy.
Description
Technical field
This utility model 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 accurate radiotherapy dosage.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.
The utility model content
The purpose of this utility model 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 purpose of this utility model is achieved in that
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 utility model 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 this utility model and prior art effectively is described, tabulation compares several apparatus for wave-energy sourcees below:
As can be seen from the table, this utility model has following characteristics than prior art:
Because this utility model 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 utility model;
Fig. 2 is the cross-sectional view of this utility model focus treatment end.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in further detail; but protection domain of the present utility model 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. 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, 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.
