Medical radiation box and radiotherapy machine

Abstract

The invention relates to the technical field of medical instruments, and provides a medical radiation box. The medical radiation box comprises a box body, a pulling up structure, a first pushing structure, a second pushing structure and a spring, wherein the box body comprises a main box structure and three cavity bodies; the cavity bodies are a radiation cavity, a storage cavity and a pushing cavity which are communicated with one another and lead to the outside of the box body; the first pushing structure and the second pushing structure are connected with each other through an interlocking structure; the pulling up structure comprises a pulling up rod and a pushing block; the spring is arranged between the pushing block and a second packaging unit. The invention further provides a medical radiotherapy machine which can be equipped with radiation structures of different amounts and different radioactive sources according to different nidi. The medical radiation box and the medical radiotherapy machine have the advantages that the production complexity, the maintenance difficulty and the application cost are low; the production cost and the running cost of an accurate radiotherapy system can be reduced greatly; the application prospect in underdeveloped and semi-developed countries and areas is wide; the potential economic benefit is higher.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a low-cost, easy-to-maintain medical radiation box and a radiation therapy machine. Background technique [0002] Malignant tumors are one of the main causes of death among residents in our country. At present, there is no specific treatment for malignant tumors. Radiation therapy (the main development is shape-conformal and dose-conformal, that is, intensity-modulated radiotherapy), chemical drug therapy and surgical treatment are the three main methods for treating tumors at this stage. About 70% of cancer patients need radiation therapy. [0003] Existing radiotherapy systems are mainly composed of two categories: one is the lesion shape acquisition system, which generally consists of dual-source helical CT, whole-body magnetic resonance imaging, radiation beam conformal design and positioning (such as CADPLAN / HELIOS three-dimensional treatment planning system ) and ...

Problems solved by technology

The other is the radiation generation system using a linear accelerator, such as the Varian 23EX linear accelerator system in the United States. Since the radiation generation system uses a linear accelerator, the production and manufacturing technology is complicated. At present, China cannot design and produce related products and relies entirely on imports. At the same time, there is no research on related equipment that is very cheap and extremely low in maintenance and use costs at home and abroad, which makes its sales price extremely expensive, and its maintenance and application costs are high, which greatly restricts its application range and increases the financial burden on patients.
