Description
Technical Field
The utility model belongs to the field of medical appliances, and particularly relates to a balloon particle sleeve for treating esophageal cancer, which is used for treating esophageal cancer.
Background
Esophageal cancer is a malignant tumor occurring in esophageal epithelium, and is a high-incidence area of esophageal cancer in northern areas of China. Early stage esophageal cancer can be treated by surgery, and middle and late stage esophageal cancer is mainly treated by radiotherapy and chemotherapy. However, since esophageal cancer is ignored because it is often asymptomatic in early stages, the course of the disease often goes into the middle and late stages when the patient develops progressive dysphagia. Patients who relapse after radiotherapy and chemotherapy or develop progress of illness with poor curative effects often can only choose palliative symptomatic treatment to prolong life.
In recent years, with the development of non-vascular puncture technology under image guidance, the radioactive particle implantation technology has the advantages of small operation wound, high therapeutic agent, small surrounding tissue damage and the like in the treatment of malignant tumors, and is more and more paid attention to clinicians, and is widely applied to the treatment of various malignant tumors at present. The radioactive particle implantation treatment is to implant a closed radioactive source with certain specification and activity into a parenchymal tumor tissue according to a preset treatment plan, and retain the radioactive source for a long time, and utilize gamma rays released by the spontaneous decay of the radionuclide to continuously irradiate tumor cells to cause the damage of the tumor cells, thereby effectively destroying focus tissues and inhibiting the proliferation of the tumor cells.
The radioactive particles are small radioactive sources, the radioactive isotopes are arranged in a titanium tube, two ends of the radioactive source are welded by laser or electron beam technology to form a sealing source, the radioactive particles which are widely used at present are generally 0.8mm in outer diameter and 4.5mm in length, and the radioactivity is generally 0.1-1 mCi.
At present, the radioactive particles are implanted mainly by percutaneous puncture under the guidance of an image, but the esophagus is a thin-walled cavity organ, and the mucous membrane and the wall structure of the lesion area of the esophagus cancer are more fragile, so that the risk of perforation and fistula of the esophagus caused by the puncture implantation is extremely high, and once the complications occur, the living quality and prognosis of a patient can be seriously affected. Thus, intra-cavity treatment techniques for radioactive particles have been proposed.
The devices applied to the radioactive particle intracavity treatment are mainly simple devices for reconstruction of an expansion bracket or a nutrition tube made of metal. The radioactive particle esophagus dilating stent has the advantages that the radioactive particle esophagus dilating stent can be clung to a focus area, so that the therapeutic conformality of the radioactive particle is good, but the radioactive particle esophagus dilating stent is expensive to counterfeit, and the stent has the risk of falling off along with the abbreviation of tumor volume after a period of treatment. The simple radioactive particle intracavity treatment device modified by the nutrition tube has the advantages of relatively simple structure, lower cost and poor conformality, and the treatment effect can be attenuated by times along with the increase of the distance between the particles and the focus due to the fact that the treatment distance of the radioactive particles is only 1-2 cm. Therefore, the radioactive particle esophageal cancer intracavity treatment device with simple structure, flexible use and high conformality is provided, namely the balloon particle sleeve for treating esophageal cancer.
