Abstract

The invention relates to a source applicator support which belongs to the field of medical instruments used for clamping and fixing afterloading unit source applicators. The source applicator support comprises a clamping assembly and a rotary assembly. The clamping assembly is mounted on an upper part of the rotary assembly. The rotary assembly comprises a rotary rod. One end of the rotary rod is mounted on a support plate through a spindle. One end of a first rocking arm is provided with a jacket. The rotary rod is arranged in the jacket in a penetrating manner. The other end of the first rocking arm is connected with one end of a second rocking arm through a rocking shaft. The other end of the second rocking arm is provided with an adjusting shaft which is provided with a rotary shaft. An upper end of the rotary shaft is fixed with the clamping assembly. The source applicator support provided by the invention is simple in structure, achieves movement in any direction and adjustment of any direction and any angle in the three-dimensional space, and is high in fixing precision.

Description

technical field [0001] The invention relates to a source applicator bracket, which belongs to the field of medical equipment for clamping and fixing after-installed source applicators. Background technique [0002] At present, afterloading radiation therapy has become one of the effective means for treating gynecological cervical tumors and rectal tumors. During the treatment, the patient's position is first fixed, and then the radiation source is sent into the patient's cavity through the source applicator for treatment. Ordinary afterloading treatment is relatively extensive and has low precision, so it does not have high requirements for the fixation accuracy of the applicator. In the early days, doctors used medical tape to fix the applicator, but the fixation was not firm, the operation was difficult, and there were potential safety hazards. [0003] With the development of science and technology, applicator brackets for fixing the applicator have gradually appeared. ...
