技术领域technical field
本实用新型涉及一种放射治疗癌症的装置，具体涉及一种阴道腔内放射治疗施源器。The utility model relates to a radiotherapy cancer device, in particular to a vaginal cavity radiotherapy source applicator.
背景技术Background technique
在我国，妇科宫颈癌、子宫内膜癌、阴道癌发病率高。中晚期放射治疗是其主要的治疗手段，而且，即便是早期患者，术后根据病变浸润情况也需放射治疗。子宫内膜癌、阴道癌在手术治疗后或不适宜手术治疗者，也要行放射治疗。放射治疗包括体外照射和经阴道腔内近距离照射。In my country, the incidence of gynecological cervical cancer, endometrial cancer and vaginal cancer is high. Radiation therapy is the main treatment method in the middle and late stage, and even for early stage patients, radiation therapy is required according to the infiltration of lesions after surgery. Radiation therapy is also required for endometrial cancer and vaginal cancer after surgical treatment or for those who are not suitable for surgical treatment. Radiation therapy includes external beam radiation and intravaginal brachytherapy.
在临床治疗中常常遇到妇科宫颈癌中晚期(IIIA期)患者阴道受侵或转移，在进行腔内近距离照射时，以往常规的方式是在子宫腔内和阴道穹窿安放施源器。然而这种放射治疗对于阴道壁中下段部位肿瘤不能很好治疗，需要另外两侧放置阴道内壁的施源器进行放疗，这种施源器不仅剂量难以计算，更重要的是放射线剂量重叠或不均匀，极易造成治疗后周围正常组织放射损伤(如直肠及膀胱)或肿瘤复发。同时，两侧的施源器容易被人体内部肌肉的包覆，放射面积减小，不能很好地治疗病灶。因此，需要一种既能进行子宫、宫颈放射治疗，同时又能兼顾阴道病变近距离放射治疗的施源器，以满足腔内放射治疗的均匀性。In clinical treatment, vaginal invasion or metastasis is often encountered in patients with advanced gynecological cervical cancer (stage IIIA). When performing intracavitary brachytherapy, the conventional way in the past is to place applicators in the uterine cavity and vaginal fornix. However, this kind of radiotherapy is not good for tumors in the middle and lower parts of the vaginal wall, and radiotherapy requires applicators placed on the inner wall of the vagina on both sides. Not only is the dose of this applicator difficult to calculate, but more importantly, the radiation dose overlaps or does not Even, it is very easy to cause radiation damage to surrounding normal tissues (such as rectum and bladder) or tumor recurrence after treatment. At the same time, the applicators on both sides are easily covered by the internal muscles of the human body, and the radiation area is reduced, which cannot treat the lesion well. Therefore, there is a need for a source applicator that can not only perform uterine and cervical radiotherapy, but also take into account the brachytherapy of vaginal lesions, so as to meet the uniformity of intracavity radiotherapy.
