In the construction of modern hospitals, the radiology department is a department integrating examination, diagnosis and treatment. Many diseases in various clinical departments must be examined by radiology department equipment to achieve clear diagnosis and auxiliary diagnosis.

[0003] Generally, a medical radiation source is fixed in the housing of a radiotherapy instrument by a bracket. When disassembling the radiation source from the radiotherapy instrument, the operator needs to stand behind the lead shielding to carry out the disassembly. The lead shielding can reduce the radiation level and thus protect the safety of the human body. However, in the operation process of this disassembly method, since the radiation source is not installed in a special shielding body and the disassembly process is complex, there will still be a problem of radiation leakage during disassembly, which is likely to cause the operator's hands, arms, etc. to be exposed to the rays without protection. At the same time, due to the material and size of the lead shielding, its overall weight is relatively heavy, and there is a problem that it is not easy to move. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-5 , the present invention provides a technical solution: a multifunctional installation bracket for a medical radiation source, including a radiation therapy instrument housing 1 and a radiation source rod 3 disposed in the inner cavity of the radiation therapy instrument housing 1.

[0027] The fixing seat 4 is fixedly connected to the top surface of the inner cavity of the radiation therapy instrument housing 1. A through - hole 4.1.1 is provided in the middle of the fixing seat 4. Among them, the fixing seat 4 includes a U - shaped plate 4.1 and connecting plates 4.2 fixed to the top ends of both sides of the U - shaped plate 4.1. Connecting holes 4.2.1 are provided on the connecting plates 4.2. The top ends of the screws sleeved in the connecting holes 4.2.1 are threadedly sleeved on the top surface of the inner cavity of the radiation therapy instrument housing 1. The through - hole 4.1.1 is provided at the central position of the U - shaped plate 4.1. At both ends of the middle of the bottom surface of the U - shaped plate 4.1, ear plates 4.3 are respectively fixed.

[0028] The top end of the threaded sleeve 5 is rotatably sleeved on the radiation therapy instrument housing 1 and is aligned with the through - hole 4.1.1. Among them, a regular hexagon groove 5.1 is provided in the middle of the top surface of the threaded sleeve 5, that is, the top end of the threaded sleeve 5 penetrates through the outer wall of the radiation therapy instrument housing 1, and the threaded sleeve 5 can be rotated through the regular hexagon groove 5.1 by an internal hexagon wrench.

[0029] The support 2 includes a base 2.1 and a screw rod 2.2 fixed to the middle of the top surface of the base 2.1 and threadedly sleeved with the threaded sleeve 5 after passing through the through - hole 4.1.1. The radiation source rod 3 is fixed to the middle of the bottom surface of the base 2.1. Among them, a slot 2.1.1 for fixedly plugging the top end of the radiation source rod 3 is provided on the bottom surface of the base 2.1. At the bottom ends of both side walls of the base 2.1, first ear seats 2.3 are respectively fixed.

[0030] The shielding housings 6 are arranged in pairs on both sides of the radiation source rod 3. The outer top ends of the shielding housings 6 are hinged to the middle of the outer end of the bottom surface of the fixed seat 4. A semi-circular groove 6.1 that is snap-fitted with the base 2.1 is provided inside the top of the shielding housing 6. A second ear seat 6.2 that is rotatably connected to the ear plate 4.3 is fixed in the middle of the top end of the outer side wall of the shielding housing 6. A third ear seat 6.3 is fixed in the middle of the side wall of the inner cavity of the shielding housing 6. The shielding housing 6 is composed of lead plates.

[0031] The top ends of the connecting rods 7 are hinged to both sides of the bottom end of the base 2.1, and the bottom ends of the pair of connecting rods 7 are hinged to the side wall of the inner cavity of the shielding housing 6. Among them, the top end of the connecting rod 7 is hinged inside the first ear seat 2.3, and the bottom end of the connecting rod 7 is hinged to the third ear seat 6.3.

[0032] In summary, during normal use, the shielding housings 6 on both sides are in an open state, and the support 2 and the radiation source rod 3 are located at the lowest position. When an operation of removing the radiation source rod 3 is required, first rotate the threaded sleeve 5. The rotating threaded sleeve 5 drives the entire support 2 and the radiation source rod 3 to move upward through the screw rod 2.2. The upward-moving base 2.1 pulls the third ear seat 6.3 on the shielding housing 6 through the connecting rod 7 to realize the gradual closing of the shielding housing 6. During the closing process of the shielding housing 6, the second ear seat 6.2 rotates relative to the ear plate 4.3. Finally, the semi-circular grooves 6.1 at the tops of the shielding housings 6 on both sides just clamp on both sides of the base 2.1 to complete sealing the radiation source rod 3 in the closed shielding housing 6 to prevent radiation leakage when the radiation source rod 3 is removed from the radiotherapy instrument.
