Problems solved by technology

[0006] The task of the present invention is to propose a new type of delivery method for micro-radiation sources in pipelines, which overcomes the problems caused by the use of wire ropes to guide and transport micro-radiation sources. The source device is large in size, and the pipeline placed in the patient's body is thick and stiff, which causes pain to the patient and cannot enter deep organs.

Embodiment Construction

[0030] figure 1 The embodiment shown is a schematic diagram of the connection of the novel liquid radiation source afterloading treatment device. The device is composed of a spherical balloon catheter 118, a gas drive device and pipeline, a liquid drive device and pipeline, a source reservoir, and a liquid micro-radiation source. The spherical balloon catheter 118 is composed of a spherical balloon 101 and a catheter 105. The wall of the spherical balloon has a three-layer structure. From the inside to the outside, there are an inner liquid wall 102, an outer liquid wall 103, and a spherical balloon wall 120. The inner and outer layers The liquid capsule cavity formed by the liquid capsule wall stores and accommodates the liquid micro-radiation source, and the spherical balloon cavity 119 is inflated and expanded to fix the spherical balloon 101 in the corresponding hollow organ in the human body. The nano-magnetic powder rubber head 104 at the front end of the catheter 105 is...

Abstract

A near-distance therapeutic apparatus using liquid radioactive source for tumor features that the air bag type front end of a catheter is arranged at a position close to tumor focus in human body, the microgranular radioactive sources are used to prepare the liquid radioactive source which is then poured in said air bag, the electromagnetic coil on the surface of body is turned on the generate a magnetic field in body to excite the magnetic rubber head to generate strong magnetism, which can attract the microgranular radioactive source to front end of catheter for killing tumor cells.

Description

Technical field: [0001] The present invention relates to a tumor brachytherapy device, in particular to a tumor brachytherapy device which inserts balloon catheters of various shapes into hollow organs of the human body, and uses a liquid state micro-radiation source to infuse the catheter balloon into the tumor brachytherapy device. The device can be effectively applied to human body internal radiation therapy for various tumors. Background technique: [0002] Tumor brachytherapy is a method of brachytherapy for tumors inside the human body. It is used in the clinical field of medicine, especially for malignant tumors of hollow organs. At present, brachytherapy for tumor patients in clinical medicine usually uses an after-loading treatment machine. First, the source applicator is inserted into the body, and then the simulated radioactive source is used to detect whether the lumen is unobstructed under the guidance of a wire rope. After the test proves that the lumen is unob...
