Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an adjustable source applicator fixing device. Background Art

[0002] An applicator refers to a special container that is pre-placed into a human cavity, duct or tissue space for the radiation source to reside or move and to implement brachytherapy. Brachytherapy is an indispensable technology for radical radiotherapy of cervical cancer. Brachytherapy for cervical cancer requires the use of a transvaginal afterloading applicator. The applicator needs to pass through the vagina into the cervix and uterus for radiotherapy. At this time, the relative position of the applicator and the human pelvic cavity needs to remain unchanged to avoid affecting the effect of brachytherapy and avoiding unnecessary radiation exposure to normal tissues. Therefore, an adjustable applicator fixing device is required.
