Tumour local comprehensive therepy method and device

Abstract

A comprehensive localized therapy method and equipment for tumor features that various endoscopes are used to inject the magnetic immune microspheres carrying biologic medicine and the antineoplastic magnetic chemical medicine into tumor focus, the liquid radioactive source is poured in the inner cavity of catheter, and an alternative magnetic field is generated around the tumor focus to induce the microspheres to generate heat and adsorbing the antineoplastic medicine to round the tumor focus. Its advantage is the combination of biotherapy, chemicotherapy, radiotherapy and thermotherapy.

Description

Technical field: [0001] The present invention relates to a method and device for local comprehensive treatment of tumors, and in particular to a method and device for injecting immunomagnetic microspheres connected with anti-tumor biological preparations and anti-tumor magnetic chemical drug preparations in tumor lesions, by generating an alternating magnetic field around the tumor in the body , a method and a device for tumor brachytherapy by aggregating magnetic drugs and inducing magnetic microsphere heating in local tumors to implement tumor immunotherapy, chemotherapy and hyperthermia, and at the same time releasing a balloon-type catheter around the tumor to perfuse a liquid radiation source for tumor brachytherapy. The method and device can be used to treat various types of human tumors. technical background: [0002] Malignant tumors are one of the most important diseases that cause human death. The research on the treatment of malignant tumors has always been the fo...

Problems solved by technology

[0008] At present, the above-mentioned various therapies are independently applied to patients. Chemotherapy and biological therapy are usually systemic treatments and are implemented through intravenous injection. Radiotherapy and hyperthermia are also performed independently. The specifications and standards of radiotherapy and hyperthermia equipment are different. Unified, patients generally need two preparations and procedures in the process of receiving radiotherapy and hyperthermia. The method is complicated, the procedures are cumbersome, and the patient’s treatment time is long. At present, some people have proposed the integrated treatment method and equipment of radiotherapy and hyperthermia. China The technology introduced in the patent (Application No. 91103108) "Integrated Radiotherapy and Hyperthermia Therapy Method and Device" is to form a set of radiotherapy and hyperthermia equipment with unified specifications and consistent driving methods by integrating the after-installation machine and thermotherapy machine. The method is realized in this way. Before radiotherapy and hyperthermia are performed on the patient, a plastic tube is first inserted into the lesion site of the human body, and then the radioactive source or hyperthermia source is inserted through the plastic tube successively under the guidance of a steel wire rope or catheter connection with a driving device. Human lesion site, hyperthermia for patients after radiotherapy

[0009] The disadvantages of the above methods and devices are that they are connected by wire ropes, and the devices for guiding radiation sources or heat sources are complicated, bulky, cumbersome to operate, and are not easy to enter the deep parts of the human body. , it is impossible to accurately adjust the direction, angle and power of the microwave antenna, and it is very difficult to precisely target the tumor lesion. In addition, there is no device to measure the surface temperature of the tumor lesion during the hyperthermia process, so it is impossible to determine the appropriate transmission power and treatment time. Basically, the treatment can only Based on subjective experience, there is no objective data to base it on. At the same time, since heating is non-selective to tumors and surrounding normal tissues, there is a great chance of damaging surrounding normal tissues. Moreover, the above methods cannot be used for local tumor therapy, chemotherapy and hyperthermia at the same time. Biotherapy
