Technical Field
The invention relates to the technical field of medical instruments.
Background
The cervical applicator is a standard three-tube applicator, is mainly used for afterloading radiotherapy of cervical cancer, and has been widely applied in the field of near-distance afterloading therapy; the uterine neck applicator comprises a uterine cavity tube and two vaginal tubes, wherein the uterine cavity tube is positioned between the two vaginal tubes, the uterine cavity tube is positioned below the two vaginal tubes, and an inverted triangle structure is formed by connecting the end parts of the uterine cavity tube and the end parts of the two vaginal tubes.
At present, when a patient is treated, the patient lies on a movable sickbed, and the patient is transferred to an operating room through the movable sickbed to be treated; before transfer, the cervical applicator needs to be inserted into the vagina and fixed on the movable sickbed, but during transfer, a patient can move relatively to the movable sickbed greatly, so that the cervical applicator can move relatively to the vagina greatly, and the internal tissue of the vagina can be damaged.
Disclosure of Invention
The invention aims to provide a wearable applicator fixing device for transfer, which aims to solve the problem that the internal tissue of a vagina is damaged due to the fact that a patient can move relatively to a movable sickbed greatly during transfer when the existing cervical applicator is fixed on the movable sickbed, and the cervical applicator can move relatively to the vagina greatly.
