Referring to the drawings, a mobile X-ray fluoroscopy apparatus according to the present invention includes an X-ray generator 2; An image concentrating unit (1); A stem 3; Position adjusting portions (4, 5, 6, 8); A body 9; And a base portion (10).

Here, the X-ray generating section 2 and the image intensifying section 1 are constituent elements for generating an X-ray to converge an image of a target object, and the X-ray absorbance varies depending on the material constituting the target body The difference in absorption rate of various organs inside the human body is shown by X-ray image (image of shadow projected on film or storage device of various structures in human body). The X-ray generating unit 2 and the image intensive unit 1 are also referred to as a mono-tank and an image intensifier, respectively.

Using such a configuration, it is used for non-destructive examination and non-invasive examination (diagnosis) which reveal abnormalities such as large intestine, small intestine, small intestine, and blood vessel as well as diagnosis of bone fracture and pulmonary tuberculosis in the human body.

Next, the cymbal 3 is a constituent element to which the X-ray generating section 2 and the image intensive section 1 are mounted. The cymbal 3 is called an "C" alphabet letter.

Next, the position adjusting portions 4, 5, 6, 8 are components for detachably supporting the cymbal 3 and adjusting the position of the cymbal 3.

More specifically, the position adjusting portions 4, 5, 6 and 8 include a bearing block portion 4 for adjusting the amount of force for fixing and fixing the cymbal 3; A stay 5 detachably supporting the bearing block portion 4; A front arm 6 on which a stay is mounted; And an actuator 8 to which the front arm 6 is mounted and which is mounted to the body 9.

3 and 6 to 8, the cymbal 3 includes a guiding portion to which the bearing block portion 4 is guided, and the bearing block portion 4 is a bearing supported by the guiding portion .

3, the bearing block portion 4 is inserted into the guiding portion at the upper end of the cushion 3 and guided to the lower right side of the cushion 3 to be fixed to the stay 5 by the bolt 11 And the like.

5 to 8, the bearing block portion 4 includes a side support bearing 12 for supporting the inner side surface of the guiding portion; An inner support bearing (13) for supporting the inner surface of the guiding portion; And an outer support bearing 14 for eccentrically supporting the outer surface of the guiding portion. here

7 and 8, by adjusting the eccentric shaft to which the outer surface support bearing 14 is fixed by a wrench or the like, the bearing block portion 4 can be deformed by a force It is possible to adjust the amount.

8, the stay 5 is fixed by using the cymbal 3 or the bearing block portion 4 and the fixing portion (bolt) 11, and the fixing portion (bolt) 11 is fixed, It is possible to remove the stay 5 from the cushion 3 or the bearing block part 4. [ Here, the fixing portion 11 can be formed by bolting.

Conventional portable X-ray fluoroscopic x-ray fixation apparatus is fixed to a stay that fixes and supports the x-ray, and the bearing block which fixes the x-ray to be smoothly slid and fixed is combined with the stay as a single component.

In the case of stay and bearing blocks, generally aluminum casting products are used in one body, and the dimensional precision of the casting itself is rather low. Therefore, when steel or stainless steel materials are used, There is a possibility that it is complicated, the force for sliding movement is large, the size is large, and the cost is increased.

Even if all the bearings are fixed to the seam, even if all the bearings are fixed by eccentricity to the bearing fixing the seam due to such conditions, it is difficult to fix the seam. In case of the defective force of the bearing fixing the seam, Weighing part and X-ray generator and weights (weights for weight balance) should be set so that weights can be balanced. Therefore, every time we adjust the combined force of bearings to fix the cymbal, The image intensifying unit and the X-ray generating unit must be disassembled.

In other words, if conventional cymbal is unbalanced or if it is necessary to adjust the cymbal, the X-ray generator and the image intensifier are removed from the cymbal, the cymbal is removed, and the bearing block, After regulating, the patient again had to re-attach the x-ray generator and the X-ray intensifier, and if there was a problem again, the above procedure had to be repeated.

However, the present invention can solve such inconvenience at its source through the above-described structure. In other words, the bearing block portion is separated from the stay, the bearing block portion to which the cushion is attached is arranged in a flat space such as a table, and then the operator adjusts while confirming with eyes, .

Furthermore, since the X-ray fluoroscopic imaging apparatus according to the present invention can be easily separated, the X-ray fluoroscopic imaging apparatus of the present invention is easy to move and install using a small elevator of a small hospital.

The stay 5 is also capable of providing rotation within a range of 270 degrees left and right with the cymbal 3 fixed and the front arm 6 is capable of moving the stay 5 in a range of 200 millimeters before and after And it is preferable to provide a rotation at an angle of 12.5 degrees to the left and right and the actuator 8 is capable of providing a movement of at least 450 mm above and below the front arm 6 to a maximum of 500 mm. The numerical values for the angular and positional movements herein are illustrative, and can be designed differently according to the intention of the designer and the convenience of the user.

Next, the body 9 is a component in which the position adjusting portions 4, 5, 6, 8 are mounted. It is the part of the mobile X-ray fluoroscopic imaging device.

Next, the base portion 10 includes a structure in which a body 9 is mounted, and a mobility such as a wheel or the like is provided below the movable X-ray fluoroscopic imaging apparatus so that the movable X-ray fluoroscopic imaging apparatus can be moved. For example, as shown in Fig. 1, the base unit 10 has three wheels at 90 degrees in the lower part thereof, so that the mobile X-ray fluoroscopy apparatus can freely move. And a braking device capable of fixing the portable X-ray fluoroscopic imaging device may be installed at the remaining 90 degrees.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various modifications and changes may be made without departing from the scope of the appended claims.
