Description

Technical Field

[0001] The invention discloses a C-shaped arm ray machine, belonging to the technical field of medical equipment. Background Art

[0002] C-arm X-ray machine, also known as C-arm X-ray machine, is a common detection equipment in the medical field. C-arm X-ray machine includes a C-shaped main body, with a ray emitting part and a ray receiving part respectively arranged at both ends of the main body. The ray emitting part and the ray receiving part are respectively located on both sides of the patient. The X-ray emitted from the ray emitting part passes through the part to be detected of the patient's body and then reaches the ray receiving part. Since X-rays will generate scattered rays when passing through the human body, the image will be fogged and the image contrast will be reduced. The grid can be used to filter out the influence of scattered rays on the image. When the thickness and density of the irradiated object are large, the use of the grid can improve the image quality.

[0003] In the C-arm X-ray machine of the prior art, the traditional filter grid is fixed (non-detachable), but for pediatric patients, the non-detachable filter grid device will increase the X-ray exposure dose for children. Therefore, there are also technical solutions for detachable filter grids on the market, but in the detachable filter grids of the prior art, it is generally necessary to separately set the plug plate and guide rail for placing the filter grid, which is costly, such as the technical solution disclosed by the Chinese invention patent with application number 202311434082.6, application date October 31, 2023, and patent name "disassembly and assembly structure". At the same time, in order to facilitate disassembly and assembly, the end of the filter grid generally protrudes from its installation cover, so the filter grid is prone to friction or collision with external objects, such as the technical solution disclosed by the Chinese utility model patent with application number 201620193736.X, application date March 14, 2016, and patent name "a new pluggable filter grid structure", which will cause safety hazards in the operating room environment. Utility Model Content

[0004] The technical problem to be solved by the utility model is: to overcome the shortcomings of the prior art and provide a C-arm X-ray machine which greatly simplifies the complexity of the machine by opening a groove on the surface of the cover shell and forming a space for placing the filter grid by using the groove.

[0005] The technical solution adopted by the utility model to solve its technical problems is: the C-arm X-ray machine includes a main body, a radiation receiving part and a radiation emitting part are arranged opposite to each other at two ends of the main body, a filter grid mechanism is arranged at the radiation receiving part, and its characteristics are: the filter grid mechanism includes a cover shell, a groove is opened at the end surface of the cover shell facing the radiation emitting part, and the filter grid is detachably located in the groove.

[0006] Preferably, one end of the groove is an open end for taking and placing the grid, a movable stopper is provided at the open end of the groove, and a fixed stopper is provided at the closed end of the groove.

[0007] Preferably, the movable limiting member is a fixed knob installed at the open end of the groove.

[0008] Preferably, the fixed limiting member is a shielding protrusion arranged at the closed end of the groove, and the shielding protrusion protrudes from the edge of the groove.

[0009] Preferably, the cover shell includes a fixed end face, the groove is opened on the surface of the fixed end face, and is vertically bent around the back side of the fixed end face to form a fence.

[0010] Preferably, armrests are provided on the sides of the main body.

[0011] Preferably, the grid is entirely located in the groove

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the present C-arm X-ray machine, a groove is provided on the surface of the housing, and a space for placing a grid is formed by the groove. Compared with the detachable grid mechanism in the prior art, the complexity is greatly simplified.

[0014] In the C-arm X-ray machine, there is no need to separately manufacture a device for placing the filter grid, so the cost is low; the four edges of the filter grid are fixed, and the fixing is firm; when disassembling, only the detachable knob needs to be taken out to remove the filter grid, which is convenient and quick.

[0015] In this C-arm X-ray machine, the filter grid is located entirely in the groove, and its edge is located on the inner side of the cover. There is no object beyond the edge of the flat cover, which greatly saves space, improves space utilization, and reduces the risk of collision and friction between the equipment and other objects when operating in the operating room.

[0021] Figures 1 to 4 It is the best embodiment of the utility model, and the following Figures 1 to 4 The utility model is further described.

[0022] like Figure 1 As shown, a C-shaped arm X-ray machine includes a C-shaped main body 3, and handrails 4 for realizing the rotation of the main body 3 are respectively arranged on the front and rear sides of the main body 3, and a ray emitting part 2 and a ray receiving part 1 are respectively arranged at both ends of the main body 3. The ray emitting part 2 and the ray receiving part 1 are arranged opposite to each other. A grid mechanism is arranged at the ray receiving part 1.

[0023] like Figures 2~4 As shown, the grid mechanism includes a cover shell 5, which includes a fixed end surface. The back side of the fixed end surface is vertically bent around to form a fence, and the cover shell 5 is fixed to the main body 3 through the fence.

[0024] A groove for placing the grid 7 is provided on the surface of the housing 5, one end of the groove is an open end, and shielding protrusions 6 are provided inwardly protruding from the middle of the other three edges of the groove. The grid 7 is placed from the open end of the groove. When the grid 7 is placed at the end of the groove, the entire grid 7 is located in the groove, and the shielding protrusions 6 on the side of the groove shield the three corresponding sides of the grid 7 to prevent the grid 7 from falling out of the groove. Since the grid 7 is entirely located in the groove on the surface of the housing 5, the risk of the grid 7 falling off during the use of the device is fundamentally avoided.

[0025] A fixing knob 8 is provided at the open end of the groove on the surface of the housing 5. The fixing knob 8 passes through the surface of the housing 5. After the grid 7 is placed in the groove, the grid 7 is positioned by the fixing knob 8. Therefore, the grid 7 is fixed in the groove by the fixing knob 8 and the shielding protrusion 6.

[0026] The specific working process and working principle are as follows:

[0027] The staff adjusts the angle of the main body 3 by the handrail so that the patient is located between the ray emitting part 2 and the ray receiving part 1. If the grid 7 needs to be set during imaging, the grid 7 is placed in the groove on the surface of the cover 5, the grid 7 is limited by a plurality of shielding protrusions 6 at the edge of the groove, and the grid 7 is locked at the opening end of the groove by a fixing knob 8.

[0028] If the grid 7 does not need to be set during imaging, the fixing knob 8 is removed from the housing 5 , and then the grid 7 is pulled out from the groove on the surface of the housing 5 .

[0029] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
