Description
Technical Field
The invention relates to the technical field of gynecological treatment instruments, in particular to a protection device for applying intra-cavity afterloading treatment to gynecological malignant tumors.
Background
The near-distance after-loading treatment is that the radioactive source applicator is placed on the surface of the tumor body in the human body lumen or is inserted into the tumor body by a needle, and the radioactive source is directly used for radiotherapy on the surface of the tumor body or in the tumor body by a computer control system. Wherein the close-range afterloading treatment has obvious treatment effect on malignant tumors such as gynecological malignant tumors, nasopharyngeal carcinoma, esophageal cancer and the like.
According to the above, when the gynecological tumor afterloading treatment is clinically carried out at present, the irradiated dose of normal tissues around the cervix is reduced while the target dose is ensured, so that the occurrence of complications related to radiotherapy is reduced, and the treatment effect is ensured. Therefore, the distance between the rectum and the bladder and a radioactive source is increased by filling gauze in the vagina, so that the radiation dose of surrounding tissues is reduced, the occurrence of radiation cystitis and proctitis is reduced, and the function of fixing an applicator and determining the position of a treated lesion is realized to a certain extent. Although most hospitals operate the gauze filling method at present, the gauze filling method still has a plurality of defects and shortcomings in clinical use; 1. the treatment operating space of self is narrow, simultaneously because of patient's position, tumour position and variation in size, after placing the applicator, again to the intravaginal gauze that fills, can cause to fill the gauze difficulty, correspondingly increases the operation degree of difficulty. 2. After the first irradiation is finished, when the second operation treatment is carried out, the position of a patient, the tumor is reduced or the sickbed is moved in the operation process, so that the gauze is not filled uniformly for the previous time, the distance between a radioactive source and the bladder and the rectum is changed, the radiation dose of the tumor focus is reduced, and the radiation dose of the bladder and the rectum is increased inevitably. 3. The gauze is frequently forgotten to be taken out after the device is taken out, so that the gauze is left out in the vagina, and counting errors caused by human factors occur. 4. Although the existing gauze is filled with the gauze, the gauze can press and hold the applicator to a certain degree to achieve a corresponding fixing effect, but the gauze is lack of a powerful supporting point, and the applicator is completely fixed by the aid of the filled extrusion force, so that the problem that the applicator is easy to displace and even fall off in clinical practical use is also solved. In view of the above drawbacks, it is actually necessary to design a protection device for the application of an intracavitary afterloading therapy in gynecological malignancies.
