多种放射疗法已用于膀胱癌的治疗,包括灌注放射性同位素、通过漂浮的气囊导管插入中心包裹的放射源,手术植入间质放疗和术中电子束放疗,但具有如下缺点:医生、护士等遭受射线照射,放疗及住院时间长,或需要手术。为此,作者设计一种遥控后负载放疗系统用于膀胱癌的治疗,通过特别设计的膀胱镜可短时内作足够剂量的照射。其方法为:尿道以2％利多卡因糊剂表面麻醉后插入有两个较大管道的膀胱镜,上管道导入照相机监测,下管道插入一根长的钴~(60)载运管,其尖端进入肿瘤的中心,尾端与放射源容器连结。然后开动传送系
A variety of radiation therapies have been used for the treatment of bladder cancer, including the infusion of radioisotopes, radioactive sources wrapped by a floating balloon catheter insertion center, surgical implantation of interstitial radiation and intraoperative electron beam radiation, but have the following disadvantages: doctors, nurses Such as being exposed to radiation, radiotherapy and hospital stay long, or need surgery. To this end, the authors designed a remote-controlled, post-loaded radiotherapy system for the treatment of bladder cancer. A specially designed cystoscope can provide adequate doses of radiation within a short time. The method is: the urethra is anesthetized with a 2% lidocaine paste and inserted into the cystoscope with two larger tubes. The upper tube is introduced into the camera for monitoring, and the lower tube is inserted into a long cobalt-(60) carrier tube. At the center of the tumor, the end is connected to a radioactive source container. Then start the transmission system
