Detailed description of the invention
Below in conjunction with detailed description of the invention, more detailed description is further done to the technical solution of the utility model.Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, all should belong to the scope of this utility model protection.
Radiotherapy is the technology that the high-energy ray utilizing radioactive source or various armarium to produce is treated tumor.Because the radioactivity of lonizing radiation has huge harm to human body, therefore need to control lonizing radiation when treating, protection human normal tissue escapes injury, and shields radioactive source in the non-treatment period.In the present embodiment, radiotherapy apparatus comprises shielding hemisphere, source body and the collimation body and the driver element of correspondence that cover conjunction from outside to inside successively, the structure of source body and collimation body is bowl-shape, and source body and collimation body all arrange multiple through hole, and radioactive source is placed in the through hole of source body.When the lead to the hole site on source body and collimation body is overlapping, radioactive source is in open state; Source body, collimation body under the driving of corresponding driver element, can rotate relatively, and after arriving an ad-hoc location, the through hole of source body and collimation body is staggered, and radioactive source conductively-closed, cannot launch lonizing radiation.
Consult Fig. 1, Fig. 1 is the structural representation of the first embodiment of a kind of manual pass source apparatus 100 for radiotherapy apparatus that this utility model provides.This device 100 comprises operating portion 110, clutch part 120, first linkage 130 and the second linkage 140.In the present embodiment, clutch part 120 is clutches 121, and operating portion 110, second linkage 140, clutch 121 are sequentially connected with the first linkage 130.
More specifically, operating portion 110 comprises operating parts 111 and guidance panel 113, and operating parts 111 extends out from guidance panel 113.In the present embodiment, operating portion 110 is arranged at the outside of the therapeutic room 5 for placing radiotherapy apparatus, and guidance panel 113 is fixedly installed on the fixing metope of therapeutic room 5.First linkage 130 is positioned at the side of clutch near radiotherapy apparatus, in order to clutch 121 and radiotherapy apparatus (sign) are in transmission connection, second linkage 140 is positioned at the opposite side of clutch 121 near operating portion 110, in order to another clutch 121 and operating portion 110 to be in transmission connection.First linkage 130 is identical with the structure of the second linkage 140, and its size can be different because of different device.
Device 100 first linkage 130 of the present utility model connects in radiotherapy apparatus at least one in the driver element of driver element and the source body collimating body, setting operation part 111 on guidance panel 113, this operating parts 111 is runner 111 in the present embodiment, and runner 111 connects the second linkage 140, clutch 121 and the first linkage 130 successively.Rotate this runner 111, the second linkage 140, clutch 121 is driven to rotate together with the first linkage 130, final first linkage 130 can drive radiotherapy apparatus to collimate at least one in the driver element of body and the driver element of source body, and collimation body or source body (not shown) are rotated.When collimating body or source body is turned to previously described ad-hoc location, achieve the shielding of the radioactive source to radiotherapy apparatus.
But the rotation of source body and collimation body that the driver element that in actual use, the first linkage 130 of device 100 connects driver element and the source body collimating body in radiotherapy apparatus controls radiotherapy apparatus treatment head is to shield simultaneously.Now, two the first linkage unit (not shown) of the first linkage 130 are connected respectively to the driver element of radiotherapy apparatus treatment head source body and collimation body.It should be noted that, if when other radiotherapy apparatus have the multilayer screen bodies such as source body, switch body and collimation body, this utility model also can be used to carry out driven shield.
Runner 111 is operating sides of operator, and in this utility model, runner 111 connects the first axostylus axostyle 112, and operator's rotating wheel 111 realizes the rotation of whole device, thus shields the radioactive source body of radiotherapy apparatus.Clutch 121 is in order to the contact cut off or set up between operating portion 110 and radiotherapy apparatus.When clutch is in the state contacted between rupturing operation portion 110 and radiotherapy apparatus, whole device 100 is separated at clutch part 120 place.Now runner 111 only can make the second linkage 140 rotate thereupon, and clutch and the first linkage 130 maintain the original state, and can not reach and shield the radioactive source of radiotherapy apparatus; When clutch 121 is in the state set up and contact between operating portion 110 and radiotherapy apparatus, whole device 100 is linked to be entirety, now rotating wheel 111, the second linkage 140, clutch 121 can be driven to rotate together with the first linkage 130, thus the collimation body of the radiotherapy apparatus be connected with two the first linkage unit (not shown) of the first linkage 130 and source body are rotated, realize shielding object after arriving assigned address.
Be different from prior art, manual pass of the present utility model source apparatus utilizes linkage to connect the collimation body of its operation part, clutch part and radiotherapy apparatus and the driver element of source body, when operating the runner of operating portion, the moment of torsion produced when runner rotates finally is transferred to the driver element of collimation body and source body, make it control collimation body and source body turn to ad-hoc location, thus radioactive source is shielded, operating without the need to entering in therapeutic room when device powers down or when producing fault, reducing the harm to staff and sufferer of lonizing radiation that source body produces.
Consult Fig. 2, Fig. 2 is the structural representation of a kind of manual pass source apparatus 200 second embodiment for radiotherapy apparatus of this utility model.This device 200 comprises: operating portion 210, clutch part 220, first linkage 230 and the second linkage 240, and wherein operating portion 210 is arranged at the outside of the therapeutic room of placing radiotherapy apparatus.
