Problems solved by technology

The deficiencies of this technology are: 1. The radioactive source wire rope cannot enter the helical groove of the source drive wheel sequentially sometimes when the treatment is completed and retracted, causing the radioactive source steel wire rope to be stuck at the guide nozzle when it is used next time, resulting in a stuck source accident; 2. 1. The wire rope of the radioactive source is loosened in the spiral groove of the source driving wheel for multiple turns, resulting in a decrease in the accuracy of the source; 3. The structure is complex, and assembly, debugging and maintenance are troublesome

Abstract

The invention provides a radioactive source conveying device of a nuclide after-loading therapy apparatus. The radioactive source conveying device comprises a true source driving mechanism, a false source driving mechanism, a source storage lead bag, a source outlet pipe, a source outlet detection mechanism and a source applicator as peripheral equipment, wherein each of the true source driving mechanism and the false source driving mechanism comprises a stepping motor, a drive plate, a driving belt, 4 pulleys, a steel wire rope, a steel wire storage pipeline, a microswitch, an access guiding nozzle, a sending guiding nozzle, a steel wire tail detection device, a channel blocking detection device and a belt tension device. The radioactive source conveying device is characterized in that: the radioactive source steel wire rope is still positioned inside the storage pipeline, and is not wound on the drive plate into a plurality of turns, so that source blocking fault is avoided; the radioactive source conveying device has the characteristics that the device is safe and reliable, the radioactive source is convenient to mount, and simple to debug and maintain.

Description

technical field [0001] The invention belongs to the technical field of internal irradiation radiotherapy equipment, and in particular relates to a radioactive source delivery device of a nuclide afterloading treatment machine. Background technique [0002] The radionuclide afterloading treatment machine is based on the optimization plan of the planning system. In the treatment room, the computer remote control is used to transmit the radioactive source to the corresponding residence position in the patient's source tube for radiotherapy. The characteristics of high dose, short range, and rapid drop of peripheral dose can effectively increase the local irradiation dose of tumors and protect surrounding normal tissues and important organs. [0003] The principle of the radioactive source delivery mechanism of the existing nuclide afterloading therapy machine is to press one end of the radioactive source steel wire rope on the source driving wheel with a pressure plate, and the...
