Cervical cancer afterloading radiotherapy source applicator

Abstract

The invention provides a cervical cancer afterloading radiotherapy source applicator. The cervical cancer afterloading radiotherapy source applicator comprises a plug cylinder assembly, a plug rod assembly, a protection assembly, a display screen and an inflator pump. The plug rod assembly is slidably arranged in the plug cylinder assembly. The protection assembly is rotatably arranged in the plugrod assembly. The plug rod assembly is connected with the display screen and the inflator pump. The plug cylinder assembly comprises a plug tube, a front positioning air bag and a rear positioning air bag. The plug rod assembly comprises a plug rod, a source application tube and a uterine cavity air bag. The plug rod is internally provided with a source application tube cavity, and the source application tube cavity is internally provided with the source application tube. The source application tube is internally provided with a radioactive source. The front portion of the plug rod is provided with the uterine cavity air bag, and the uterine cavity air bag is connected with the inflator pump. The protection assembly comprises an inner tube. The cervical cancer afterloading radiotherapy source applicator can be rapidly and accurately positioned, positioning is firm, the inner wall of a uterus can be supported, and a focus position is well exposed; and the irradiation area and angle canbe adjusted, the damage of radiotherapy to non-lesion tissues is greatly reduced, and the side effect of radiotherapy is reduced to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an applicator for post-installation radiotherapy for cervical cancer. Background technique [0002] Cervical cancer is the most common gynecological malignancy, and its morbidity and mortality ranks second among female malignant tumors, second only to breast cancer. Persistent infection of high-risk HPV is closely related to the occurrence of cervical cancer. Cervical cancer can be prevented by regular screening and vaccination. my country has actively carried out the prevention and treatment of cervical cancer since the late 1950s, and the national cervical cancer mortality rate dropped by 69% from the 1970s to the 1990s. However, with the rapid development of my country's society and economy, changes in individual sexual behavior and other behavioral patterns, and the increase in cervical cancer risk exposure factors, the prevalence of cervical cancer has d...

Problems solved by technology

However, the existing after-loaded radiotherapy source applicator is not fixed firmly, it is easy to slip off and move, and it cannot fully display the lesion, and it is easy to be unable to completely perform radiotherapy on the lesion, or to perform radiotherapy on many good tissues, causing damage to good tissues. Cause a lot of harm to the patient, which is not conducive to the rapid recovery of the patient
