Description
Technical Field
The utility model relates to a medical appliance, in particular to a breast cancer brachytherapy applicator.
Background
Brachytherapy is the irradiation of a tumor site of a patient with a radioactive source implanted directly into the patient through an applicator or delivery catheter. The basic characteristic is that the radioactive source is close to the tumor tissue, which can obtain effective killing dose, and the adjacent normal tissue falls off rapidly with the increase of the radiation dose and has lower receiving capacity.
In the research of GEC-ESTRO tissues, the patient can independently receive brachytherapy as auxiliary treatment, the local control rate of the radiotherapy by the surgical combined tissue insertion distance is 80-90%, the tolerance is good, and the breast cancer patient can well protect the skin, the heart and the lung. Compared with external irradiation, the focal part can be irradiated at an accelerated speed through brachytherapy, and the treatment time is controlled to be 4-5 days. For breast cancer patients with low recurrence risk, external irradiation radiotherapy can be replaced by interstitial brachytherapy.
At present, in brachytherapy of breast cancer patients, a method of performing interstitial insertion radiotherapy after fixing a focal region through a template is widely applied, and although a multi-channel interstitial insertion technology is very flexible and can be applied to focuses of different sizes, the method has high technical requirements on integral insertion implementation, increases wounds of different degrees, and brings pain to the patients in the treatment process. Currently, in brachytherapy of breast cancer patients, there are available balloon catheters that can be placed by a surgeon after tumor resection, such balloon catheters have only one channel in the center for radiotherapy, so there are strict requirements on the placement method, the symmetry of the balloon, the consistency of the balloon and the position where the balloon is placed, and the thickness of the covered skin, and there are only three standard sizes of 4 × 5, 4 × 6 and 5 × 6, which are relatively fixed in size specifications.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a breast cancer brachytherapy applicator to solve the problems of difficult operation, low accuracy and inconvenient use in the prior art.
The utility model discloses a realize like this: a breast cancer brachytherapy applicator comprises a shaft lever, a fixing cap, an adjustable arc-shaped frame, an adjusting device and a hose; the adjustable arc-shaped frame is characterized in that the shaft lever is a long straight lever, the fixing cap is arranged at one end of the shaft lever, the adjusting device is arranged in the middle of the shaft lever, the adjustable arc-shaped frame is arranged between the fixing cap and the adjusting device, one end of the adjustable arc-shaped frame is fixed on the fixing cap, the other end of the adjustable arc-shaped frame is in contact with the adjusting device, the curvature of the adjustable arc-shaped frame is controlled by adjusting the position of the adjusting device on the shaft lever, and the hose is fixed on the adjustable arc-shaped frame.
The adjustable arc-shaped frames are a plurality of and are uniformly distributed around the shaft rod.
And the adjustable arc-shaped frame is provided with a fixing ring for fixedly connecting the hose in a penetrating way.
And one flexible pipe is fixed on each adjustable arc-shaped frame, and one end of each flexible pipe is used for being connected with a therapeutic machine.
The middle part of the shaft lever is provided with threads, the adjusting device is provided with corresponding threads, and the position of the adjusting device is adjusted by rotating the adjusting device.
The utility model discloses a hose is fixed on adjustable arc frame, and its crookedness is adjusted through adjusting device to adjustable arc frame to adjust the crookedness of hose. The therapeutic machine connected with the hose selects the hose to be introduced into the radioactive source according to the position of the tumor, and then the bending degree of the hose is adjusted according to the requirement, so that the hose is attached to the shape of the breast focus, the radioactive source can better irradiate the local tissue, and the eccentricity problem of the tumor is solved.
