[0002] Radiotherapy is one of the main treatment methods for gynecological tumors (cervical cancer, vaginal cancer, endometrial cancer, etc.), and includes intracavitary afterloading therapy and external irradiation therapy. Late-stage tumors of cervical cancer and endometrial cancer are characterized by large size, lateral growth, and close proximity to organs at risk. Intracavitary radiotherapy uses a three-tube applicator, which can be used in conjunction with an implant needle during the process.

[0003] The inventors of the present application discovered during long-term research and development that existing treatment methods often use three-dimensional post-loading applicators, but the needle insertion angles are only vertical insertion, parallel needle arrangement, or can only have slight angles. For tumors with irregular sizes and shapes, the needle insertion position during treatment is not ideal, and the treatment has limitations. Utility Model Content

[0004] The present application provides a close-range afterloading treatment applicator support device to solve the problem of unsatisfactory needle insertion position when a three-dimensional afterloading applicator is used to treat tumors of irregular volume and shape in the prior art.

[0005] In order to solve the above technical problems, a technical solution adopted by the present application is: to provide a brachytherapy applicator support device, wherein the brachytherapy applicator support device comprises:

[0006] A support assembly, comprising a first support and a second support, wherein one end of the first support is provided with a source applicator stopper and a connector, the source applicator stopper is connected to a uterine cavity source applicator, the other end of the first support is connected to one end of the second support, and the connector is sleeved on the source applicator stopper;

[0007] The implant needle limiting piece has limiting grooves on both sides for connecting the implant needle; the main body of the implant needle limiting piece is provided with a first through hole for connecting the connecting piece;

[0008] A fixing member, one end of which is connected to the treatment bed connecting rod, and the other end of which is connected to the other end of the second bracket.

[0009] The beneficial effects of the present application are as follows: Different from the prior art, the present application provides a bracket device for a close-range afterloading treatment applicator, which includes: a bracket assembly, including a first bracket and a second bracket, one end of the first bracket is provided with a source applicator limiter and a connector, the source applicator limiter is connected to the uterine cavity applicator, the other end of the first bracket is connected to one end of the second bracket, and the connector is sleeved on the source applicator limiter; an implant needle limiter, with limit grooves on both sides respectively for connecting the implant needle; a first through hole is provided on the body of the implant needle limiter for connecting the connector; a fixing member, one end of which is connected to the treatment bed connecting rod, and the other end is connected to the other end of the second bracket. The fixation between the uterine cavity applicator and the treatment bed is achieved by the bracket assembly and the fixing member, and the implant needle can be fixed on the implant needle limiter at a vertical or oblique angle as needed, which solves the problem of unsatisfactory needle insertion position when the three-dimensional afterloading applicator is used to treat tumors of irregular volume and shape in the prior art.
