Description

technical field [0001] The invention belongs to the field of tumor treatment, and relates to a multiple temperature-controlled chemotherapy and thermotherapy device, in particular to a three-dimensional porous graphene-assembled drug temperature-controlled chemotherapy and thermotherapy device for gastrointestinal tumors. Background technique [0002] At present, various tumor diseases faced by human beings are increasing year by year, and malignant tumors, namely cancer, have become one of the major diseases that threaten human health globally. At present, the main treatment methods for cancer include chemotherapy, radiotherapy, surgery, etc., but these treatment methods all have certain technical limitations. For example, the drug delivery of chemotherapy has the problem of non-targeting, and the treatment mechanism is single, drug resistance is prone to occur, the side effects are relatively large, and patients should not take it for a long time; and surgical treatment wi...

Problems solved by technology

However, there are still some problems in the technical development of hyperthermia, such as: the problem of uneven heat distribution, which will cause the heat in some areas to be insufficient to kill all tumor cells, and the heat in some areas may damage normal cells. It is difficult to cure the tumor completely

There are obviously great defects in the hyperthermia method, that is, the non-specificity of heat transfer, which can easily cause damage to normal tissues and organs around the tumor, and there are also a series of problems such as poor therapeutic effect on deep-seated tumors

[0003] At present, how to effectively overcome the series of defects in tumor treatment technology, such as: how to solve the problem of heat transfer specificity in hyperthermia; how to accurately implement heat targeting and accumulation to tumor sites; how to implement precise temperature control chemotherapy or hyperthermia; How to implement directional and multiple chemotherapy in a targeted manner according to the characteristics of the patient's tumor site; how to organically combine multiple temperature-controlled chemotherapy, hyperthermia and targeted therapy to improve the synergistic effect of tumor treatment, etc. These are series that need to be solved urgently important technical issues
