Description
Technical field
The present invention relates to radioactive source flip chip technology field, more particularly to a kind of stem apparatus and system.
Background technology
Radiotherapy equipment is a kind of Medical Devices using radiation cure human body diseases.At present, for using radiation
Source produce radioactive ray radiotherapy equipment, conventional stem be radioactive source export and/or lead-in mode it is as follows：
Before radioactive source is imported into radiotherapy equipment, a shielding is built with shielding slab in the outside of radiotherapy equipment
The operating room of radioactive ray, is commonly called as hot cell, will be placed in for the source of bank savings tank and pick device that deliver radioactive source in hot cell, by rising
Hang equipment to sling the hanging basket for being provided with radioactive source from pig, be placed in the specified location in hot cell, by hot field operation
Pick device imports radioactive source in radiotherapy equipment.After stem work is completed, then remove the hot cell built by shielding slab.
However, there is problems with the mode being had its source in hot cell above by building：
Firstth, because the shielding slab for building hot cell is made up of heavy metal material, and the space built will accommodate source of bank savings tank
And the operating space of pick device, so building hot cell and removing hot cell consuming time length, labor intensity is big, operation difficulty is big；
Secondth, after a certain period of use time, radioactive source dies down radiotherapy equipment because of decay, such as the half of cobalt -60
The phase declined for 5.27, then in order to ensure its close rate in focus, needs to change radioactive source within each 6 years or so, will
Old radioactive source export in radiotherapy equipment, new radioactive source is imported, so, it is necessary to hot cell is built again, but again
It is secondary to build hot cell difficulty greatly；
If the 3rd, radiotherapy equipment breaks down during use, especially treatment head failure when, maintainer need to enter
Enter therapeutic room, because radioactive source can not be removed easily, when being overhauled to it radiation leaks easily occur for staff,
Add the radiation risk of maintainer.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides one kind stem apparatus and system, hot cell need not built
In the case of, the importing and/or export of radioactive source can be realized.
In order to reach the object of the invention, the embodiments of the invention provide one kind stem device, described device includes：Support
Frame；Have its source tank, is arranged on support frame as described above, including stem tank body and shield door, wherein, the shield door be used to open or
Close the stem tank body；Pull bar, stretch into the stem tank body through the stem tank body, and opened in the shield door
When, radioactive source can be pulled in or released the stem tank body by the pull bar.
The embodiment of the present invention additionally provides a kind of stem system, including：Radiotherapy equipment, and above-mentioned stem device；
Wherein, the stem device is connected with the treatment head of the radiotherapy equipment, when the shield door is opened, the stem dress
Put and the radioactive source in the stem tank is pushed into the treatment head of the radiotherapy equipment by the pull bar, or from described
Radioactive source is pulled out in the treatment head of therapeutic equipment to the stem tank.
The embodiment of the present invention additionally provides a kind of stem system, including：Source of bank savings tank, and above-mentioned stem device；Wherein, institute
State stem device to dock with the source of bank savings tank, when the shield door is opened, the stem device is by the pull bar by described in
Radioactive source in source of bank savings tank pulls in the stem tank, or the radioactive source in the stem tank is pushed into the source of bank savings tank.
Compared with prior art, the stem device in the embodiment of the present invention, including support frame, stem tank and pull bar, wherein,
The stem tank is arranged on support frame as described above, and stem tank includes stem tank body and for opening or closing the stem
The shield door of tank body；The pull bar is stretched into the stem tank body through the stem tank body, when the shield door is opened, institute
The stem tank body can be pulled in radioactive source or release by stating pull bar.The stem device can be by radioactive source from interfaced dress
Middle export is put, is stored in stem tank, the radioactive source being stored in stem tank can also be imported into interfaced device.
So as to, radioactive source whether is installed for therapeutic equipment, or the radioactive source in therapeutic equipment is changed, hot cell need not be built,
Device can of having its source imports radioactive source new in source of bank savings tank in interfaced radiotherapy equipment, or, will be right with it
In the radiotherapy equipment connect old radioactive source export to a source of bank savings tank and by radioactive source new in another source of bank savings tank imported into
It is simple to operate in its radiotherapy equipment docked, it is time saving and energy saving；In addition, when the treatment head fail of therapeutic equipment, lead
Source device can also be easily interfaced, exports and stores the radioactive source in treatment head, avoids the radiation risk of maintainer.
