Technical Field
The utility model relates to the technical field of particle radiotherapy, in particular to a cavity tumor radiotherapy particle implantation application.
Background
The cavity tumor refers to the tumor growing in organs or pipelines of the cavity of the human body, such as the tumor growing in esophagus, bile duct, stomach and intestine, trachea, urethra and the like. The cavity tumor often blocks the normal human body cavity to cause obstruction of the relevant viscera of the patient, and a series of clinical symptoms are generated, for example, the biliary tract may generate symptoms such as fever, jaundice, pain and the like due to the obstruction of the tumor, and severe cases also cause obstructive suppurative cholangitis to cause shock and change of the mind of the patient; as another example, intestinal obstruction may cause abdominal pain, nausea, vomiting, abdominal distension, inability to relieve constipation, and severe cases may cause perforation of the intestines and consequently diffuse peritonitis, and septic shock death.
The radioactive particle therapy is an interventional therapy means widely applied clinically, which is to insert radioactive particles into a cavity, and then utilize rays released by the particles to cause irreversible damage to tissues and cells in an effective treatment range, thereby killing lesions. After the radioactive particles are inserted into the tumor area, the effective treatment is within 3 half-lives; for example: 125 iodine particles are selected, the half life period is 59.6 days, and the uninterrupted radiotherapy for 180 days can be maintained after the implantation, and the local radiotherapy dosage can be up to 160Gy, so that the tumor cells in the implantation area can be killed in a lethal manner.
At present, the cavity tumor radiotherapy is mostly temporarily implanted by adopting the way that particles are packaged into a particle tube through gel, and then the particle tube is punctured and inserted into a lesion, and the particle tube adopted by the way has no channel, so that the cavity cannot be completely plugged, only a particle tube which is much thinner than the cavity can be adopted, the particles cannot be completely attached to the inner wall of tissues such as esophagus, intestinal tract and the like, and the radiotherapy effect of cancers such as esophagus cancer, intestinal cancer and the like is greatly reduced; in addition, the distribution range and the dose of the radiotherapy particles packaged into the particle tube cannot be changed according to the treatment progress of diseases in the whole radiotherapy period, the later treatment effect can be reduced due to wrong particle distribution, meanwhile, the later radiotherapy dose can be too large due to the fixation of the particle dose in the whole treatment period, and particularly for some patients with fast disease improvement, the radiotherapy is carried out according to the particle metering in the initial treatment period, so that longer radiotherapy radiation is necessarily caused to surrounding normal tissues, and the optimality of the whole radiotherapy process is poor.
