Individual near-distance treatment source applicator and manufacturing method thereof

Abstract

The invention discloses an individual near-distance treatment source applicator and a manufacturing method thereof and belongs to the field of medical apparatus and instruments. The individual near-distance treatment source applicator comprises a source applicator tube. Source applicator line ducts which are axially communicated to two ends of the source applicator tube are formed in the annular end face of the source applicator tube. Two ends of the source applicator tube are a focus treatment end and a fixing end respectively. The focus treatment end is connected with an individual planting sleeve which allows the source applicator line ducts to be exposed and is matched with a focus. The source applicator has the advantages that the source applicator is matched with the height of the anatomical contour of the vagina, the fornix and the like of an individual patient and can closely attach to the focus area, the source applicator can have a plurality of source applicator line ducts, the positions of the source applicator line ducts can be adjusted according to the growing positions, sizes and shapes of tumors, and individual near-distance radiotherapy is achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an individualized brachytherapy applicator and a manufacturing method thereof. Background technique [0002] Three-dimensional intracavitary brachytherapy is a form of radiation therapy. It can precisely place the radiation source in or near the malignant tumor, and use high-energy rays to kill tumor cells. It can directly kill the tumor, with good therapeutic effect and low recurrence rate. The advantages are widely used in the treatment of clinical tumors. [0003] At present, the radiation therapy technology mainly relies on the source applicator which is difficult to reside in the lesion well, and its configuration diameter is also limited. Radiotherapy cannot be performed well. When the distance is far away, the radiation dose reaching the lesion is weakened, which seriously affects the radiotherapy effect and leads to tumor recurrence. In order for the lesion to receive suff...

Problems solved by technology

[0003] At present, the radiation therapy technology mainly relies on the source applicator which is difficult to stay in the lesion well, and the diameter of its configuration is also limited. Radiotherapy cannot be performed well. When the distance is far away, the radiation dose reaching the lesion is weakened, which seriously affects the effect of radiotherapy and leads to tumor recurrence. In order for the lesion to receive sufficient radiation dose, it is necessary to increase the dose of the radioactive source. It will also cause the normal skin tissue near the lesion to be damaged by over-irradiation, causing early complications of radiation
