Description

Technical field

The present application relates to the technical field of medical devices, in particular to an analog light source adjusting device, analog light source equipment and radiotherapy equipment.

Background technique

Radiation therapy is an important means of treating cancer, and radiotherapy equipment (referred to as radiotherapy equipment) is a key medical device for radiotherapy. The radiotherapy equipment usually includes a treatment head, the treatment head includes: a medical electronic linear accelerator, the radiation source of the medical electronic linear accelerator can emit a high-energy X-radiation beam, and then obtain the required light through a collimating system (including a multi-level collimator) The contour of the radiation field illuminates the target area of the patient to achieve the purpose of treating tumors.

In order to achieve accurate treatment of the patient, before the treatment, the patient needs to be positioned so that the radiation field coincides with the target area of the patient. However, the X-radiation beam emitted by the radiation source is invisible light. Usually, it is also necessary to provide a simulation light source and a mirror on the treatment head, and use the visible light field generated by the simulation light source and the mirror to simulate the radiation field generated by the radiation source. In theory, the optical path from the simulated light source to the projection surface (reflector) needs to be equal to the distance from the radiation source to the same projection surface, that is, the position of the simulated light source and the radiation source are symmetrical with respect to the reflector.

However, due to errors in the manufacturing and assembly process of the treatment head, the actual positions of the simulated light source and the mirror may deviate from the theoretical position, resulting in a lower treatment accuracy of the treatment head.

The first adjusting rod 13 is configured to drive the first base 11 to move in the first direction x. Exemplarily, the first connecting member 12 is provided with a first through hole (not shown in FIGS. 3 and 4 ), and the first adjusting rod 13 can pass through the first connecting member 12 and the first base 11 through the first through hole Active connection. The extending direction of the first adjusting rod 13 may be parallel to the first direction x. The first adjusting rod 13 may be an adjusting bolt. The first adjusting rod 13 may be screwed to the first base 11. When the first adjusting rod 13 rotates, the first base 13 extends in the extending direction of the first adjusting rod 13 The upward movement causes the simulated light source body to move in the first direction x.

After the adjustment of the simulated light source body by the first adjustment assembly 10 is completed, in order to avoid that the first base 11 can continue to move in the first direction x, the position accuracy of the position of the simulated light source body in the first direction x is low. The first adjusting assembly 10 may further include a first fixing member 14. The first fixing member 14 may include: a first fixing groove 141 provided on the first base 11, and a first tightening member passing through the first fixing groove 141 Fixed bolt 142, the first fastening bolt 142 may or may not contact the inner surface of the first fixing groove 141, the first fastening bolt 142 is movably connected to the third adjustment assembly 30, the first fixing groove 141 The extension direction is parallel to the first direction x. For example, the first fastening bolt 142 may be movably connected to the third base 31 in the third adjustment assembly 30, and the extending direction of the first fastening bolt 142 may be perpendicular to the plate surface of the third base 31.

Therefore, in actual use of the embodiment of the embodiment of the present application, only the first fixing member 14 may be provided, but the guiding is rough guidance. In order to achieve fine guidance, it is also necessary to provide the first guide 15.

FIG. 4 illustrates schematically that the number of the first guides 15 is two and the number of the first firmware 15 is one. At this time, the two first guide grooves 151 and one first fixing groove 141 in the first adjusting assembly 10 may be disposed at different positions of the third base 31 so that the two first guide members 15 and one first fixing The member 14 can restrict the first base 13 to move only in the first direction x, avoid the movement of the first base 13 in other directions, and further improve the stability of the position adjusting device 100.

The second adjusting rod 23 may be screwed to the second base 21. When the second adjusting rod 23 rotates, the second base 21 extends in the extending direction of the second adjusting rod 23 The upward movement causes the simulated light source body to move in the second direction y.

After the adjustment of the simulated light source body by the second adjustment component 20 is completed, in order to avoid that the second base 21 can continue to move in the second direction y, the position accuracy of the position of the simulated light source body in the second direction y is low. The second adjusting assembly 20 may further include a second fixing member 24, and the second fixing member 24 may include: a second fixing groove 241 provided on the second base 21, and a second tightening member passing through the second fixing groove 241 A fixed bolt 242, the second fastening bolt 242 may or may not contact the inner surface of the second fixing groove 241, the second fastening bolt 242 is movably connected to a preset component, and the extending direction of the second fixing groove 241 Parallel to the second direction y.
