  • adenocarcinoma of the prostate usually occurs in the back of the prostate, which is very close to the rectal wall. Since the prostate moved during treatment, the radiation was irradiated extensively, in which case most of the rectal wall adjacent to the prostate was exposed to radiation. This will be described based on the accompanying drawings.
  • Proximity radiotherapy is expected to be widely used as a representative treatment method for prostate cancer due to the high success rate and satisfaction of patients.
  • Such radiotherapy has the principle of injecting a seed containing a radioisotope, a radio-emitting material, in the prostate and near the tumor, thereby causing the isotope to intensively destroy the cancerous tissue of the tumor.

Abstract

La présente invention concerne un cathéter pour fixer la prostate. La présente invention vise à fournir un cathéter de fixation de prostate, qui est inséré dans le rectum de façon à limiter le mouvement de la prostate au moment d'une radiothérapie pour le cancer de la prostate, qui comprend une partie de ballonnet pour fixer la prostate au niveau de sa partie d'extrémité avant, qui peut détecter le niveau d'exposition de la partie de ballonnet, et qui permet à la position de la partie de ballonnet d'être mise en contraste avec précision, en augmentant ainsi la précision d'une intervention. Par application de la présente invention, la partie de ballonnet peut être insérée avec précision à l'emplacement de la prostate et être étendue jusqu'à ce dernier qui varie en fonction du patient. De ce fait, le mouvement de la prostate peut être réduit à un minimum. Enfin, un organe ou une cellule autre que la prostate peut être empêché d'être exposé au rayonnement. En outre, par application de la présente invention, il est possible de détecter le niveau d'exposition à l'aide d'un dosimètre en verre, qui est fixé à la partie de ballonnet, et vérifier ainsi avec précision l'état d'un patient.
