Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an integrated X-ray source. Background Art

[0002] C-arm X-ray machine, also known as C-arm X-ray machine, refers to X-ray equipment with a C-shaped frame, which is used for real-time dynamic imaging during surgery; C-arm has the advantages of small radiation dose, low infection risk, small footprint, and easy mobility. It is currently widely used in medical fields such as orthopedics, interventional treatment, urology and pain treatment.

[0003] As a key component of the C-arm X-ray machine, the X-ray source needs to meet the technical specifications of small size and large heat capacity. However, due to the limitation of high-voltage insulation, it is difficult to reduce its size. Therefore, in order to meet the requirements of long-term, high-power continuous exposure, the X-ray source needs to have as large a heat capacity as possible. The cost of using an X-ray tube with large heat capacity will increase significantly, and as the exposure time and power increase, the heat will continue to accumulate. Therefore, heat dissipation for the X-ray source is also particularly critical.

[0004] At present, the heat dissipation measures for X-ray sources are mainly:

[0005] (1) Heat is dissipated by the natural flow of transformer oil temperature difference inside the X-ray source. Due to the poor fluidity of transformer oil, the heat dissipation effect is general;

[0006] (2) Installing an oil pump inside the X-ray source to force transformer oil convection to improve its heat dissipation performance. This method inevitably increases the volume of the X-ray source while improving its heat dissipation performance;

[0007] (3) A heat dissipation device is provided outside the X-ray source to accelerate the heat dissipation of the X-ray source box.

[0008] The above heat dissipation measures can improve the heat dissipation performance of the X-ray source to a certain extent. However, after long-term use or high-power exposure for a period of time, the temperature of the X-ray source may exceed the operating temperature or the shell temperature of the X-ray source may exceed the human body safety temperature, and the machine has to be shut down and restarted after the X-ray tube cools down.

[0044] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, device, product or equipment that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0045] In one embodiment of the present invention, an integrated X-ray source is provided. Figure 1 and Figure 2 The X-ray source comprises an oil tank 1, a first heat sink 2, a second heat sink 3 and an X-ray source component 4, wherein the X-ray source component 4 comprises a booster module 41 and a tube module 42 which are electrically connected, wherein the booster module 41 comprises a transformer, and the transformer is configured to provide a high voltage to an X-ray tube 421 in the tube module 42, wherein:

[0046] The oil tank 1 is configured to accommodate the X-ray source component 4, and the inside of the oil tank is filled with transformer oil 5. When the X-ray tube generates X-rays, only 1% of the energy of the electrons will generate X-rays, and the remaining 99% will generate heat energy, which increases the temperature of the tube. Convection is formed between the high-temperature X-ray tube and the low-temperature insulating oil, which can increase the heat capacity of the tube to a certain extent.

[0047] The first heat dissipation device 2 includes a heat dissipation pipe 21, which is a hollow communication structure, wherein the middle portion of the heat dissipation pipe 21 is arranged inside the oil tank 1 and in contact with the transformer oil 5, and both ends of the heat dissipation pipe 21 are configured to be connected to and communicate with the outside of the oil tank 1, and the portion of the heat dissipation pipe 21 passing through the oil tank 1 is sealed and connected to the oil tank 1;

[0048] The second heat dissipation device 3 is disposed outside the oil tank 1 , and is configured to dissipate heat derived from the heat dissipation pipe 21 .

[0049] During use, the heat generated by the X-ray tube is transferred to the transformer oil in the form of thermal radiation and heat transfer. After absorbing the heat, the temperature of the transformer oil continues to rise. The first heat sink absorbs the heat in the oil and brings the heat to the outside of the oil tank 1, and further dissipates the heat using the second heat sink 3, which can effectively improve its heat dissipation performance. The probability of thermal breakdown caused by excessive temperature inside the X-ray source is reduced, and the continuous operation time of the X-ray source can be extended.

[0050] In this embodiment, the boost module 41 is electrically and mechanically connected to the bulb module 42 , and the heat dissipation pipe 21 is disposed at a position close to the bulb module 42 .

[0051] See also Figure 1 and Figure 4 The tube module 42 includes an X-ray tube 421, a sleeve 422, a bracket 423 and an upper connector 424. The sleeve 422 is sleeved outside the X-ray tube 421 and fixedly connected to the X-ray tube 421; the sleeve 422 is made of metal material and has good thermal conductivity and shielding properties. Preferably, the sleeve 422 is made of steel.

[0052] The bracket 423 is arranged at the upper end of the sleeve 422. Specifically, one bracket 423 is arranged at the front and rear sides of the sleeve 422. The bracket 423 is provided with a first through hole. A fastener is used to pass through the first through hole and is fixedly connected to the oil tank 1.

[0053] See also Figure 5 , side panels 411 are provided on both sides of the boost module 41, and the side panels 411 are detachably connected to the bracket 423 through fasteners. The boost module 41 is detachably connected to the fuel tank 1. Specifically, the bottom of the boost module 41 may be detachably connected to the bottom of the fuel tank 1 through fasteners, or the side of the boost module 41 may be detachably connected to the side of the fuel tank 1 through fasteners. The present application does not limit the protection scope of the present application by the specific connection method between the boost module 41 and the fuel tank 1.

[0054] See also Figure 1 and Figure 3 The heat dissipation pipe 21 is arranged in the middle part of the oil tank 1 and includes a circuitous bending structure. The heat dissipation pipe 21 is preferably an oxygen-free copper pipe.

[0055] like Figures 1 to 3As shown, the oil tank 1 includes a box body 11 and a cover plate 12, the box body 11 and the cover plate 12 are sealed and connected, an oil filling hole 121 is arranged on the cover plate 12, and correspondingly, a sealing member sealed and connected to the oil filling hole 121 is provided. Preferably, the cover plate 12 is made of metal material, preferably aluminum alloy, which is light in weight, and has good thermal conductivity and corrosion resistance. A groove is provided on the side of the cover plate 12 facing the box body 11, and the arrangement of the groove is consistent with the arrangement of the heat dissipation pipe 21, and the heat dissipation pipe 21 is arranged in the groove. Inlaying the heat dissipation pipe 21 in the groove of the oil tank cover plate 12 can further reduce the internal space of the oil tank 1 occupied by the heat dissipation pipe 21, which is conducive to reducing the volume of the X-ray source.

[0056] The second heat dissipation device 3 includes a radiator 32, or a combination of a heat dissipation fan 31 and a radiator 32. The number of the heat dissipation fan 31 can be one or more, which is specifically set according to actual use requirements. The number of the radiator 32 can be one or more, which is specifically set according to actual use requirements.

[0057] Preferably, the heat dissipation fan 31 is disposed at a position close to the outlet end of the heat dissipation pipe 21. The radiator 32 is also preferably disposed at a position close to the outlet end of the heat dissipation pipe 21.

[0058] The heat dissipation pipe 21 is disposed on the cover plate 12 on a side facing the box body 11, see Figure 1 and Figure 3 The heat dissipation pipe 21 has a first port 211 and a second port 222 extending to the outside of the oil tank 1. The two heat dissipation fans 31 are detachably arranged on the side of the box body 11, and the radiator 32 is arranged on the side of the heat dissipation fan 31 away from the box body 11, that is, the heat dissipation fan 31 is arranged between the radiator 32 and the oil tank 1, and the upper end of the radiator 32 is detachably connected to the cover plate 12. The first port 211 and the second port 222 of the heat dissipation pipe 21 extend to the position of the heat dissipation pipe 21, such as Figure 2 The cooling fan 31 is provided with a channel ( Figure 1 and Figure 2 (not shown), the first port 211 and the second port 212 are two ports, one of which is sealed and connected to one end of the channel, and the other port is sealed and connected to the other end of the channel, and the coolant circulates in the heat dissipation pipe 21 and the channel.

[0059] In this embodiment, the heat inside the X-ray source is transferred to the outside of the oil tank 1 by circulating the coolant in the channels of the heat dissipation pipe 21 and the radiator 32, and the air convection is accelerated by the cooling fan 31, and the heat dissipation outside the oil tank 1 is further accelerated by the large-area heat dissipation fins 321 on the radiator 32, which can effectively improve the heat dissipation performance of the X-ray source.

[0060] In another embodiment of the utility model, different from the above embodiment, the two ports of the heat dissipation pipe 21 are not connected to the channel on the radiator. In this embodiment, one of the first port 211 and the second port 212 is connected to the inlet end of a circulation device, and the other port is connected to the outlet end of the circulation device. The circulation device is configured to control the circulation of the coolant in the heat dissipation pipe 21. The circulation device can be a pump or a circulation tower. Specifically, the circulation device can be directly arranged outside the oil tank of the X-ray source, or it can be an external circulation device. The circulation device drives the coolant in the heat dissipation pipe 21 to circulate and dissipate heat, thereby accelerating the heat dissipation in the oil tank.

[0061] It should be noted that, in this embodiment, one or a combination of the cooling fan 31 and the radiator 32 may be provided on the outside of the oil tank 1, or no cooling fan 31 or a combination of the cooling fan 31 and the radiator 32 may be provided, which may be provided according to the cooling requirements and cost requirements. Taking the simultaneous provision of the cooling liquid, the pump, the cooling fan 31 and the radiator 32 as an example, during use, the heat generated by the X-ray tube is transferred to the transformer oil in the form of heat radiation and heat transfer. After the transformer oil absorbs the heat, the temperature continues to rise. The heat dissipation pipe 21 absorbs the heat in the oil, so that the cooling liquid inside it vaporizes and absorbs heat, thereby dissipating the heat of the transformer oil. The pump drives the cooling liquid to circulate in the heat dissipation pipe, so as to bring the heat in the oil tank to the outside of the oil tank. The large-area heat sink can further accelerate the heat dissipation to the outside of the oil tank. At the same time, the fan inside the heat sink further accelerates the air convection, so that the heat dissipation efficiency is higher, and the X-ray tube can be ensured to work stably under high power and for a long time.

[0062] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0063] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
