The present invention relates to a medical diagnostic device, and more particularly, to a medical diagnostic device having an arm structure capable of adjusting the length in a medical diagnostic device using X-ray imaging.

In general, an X-ray medical diagnostic apparatus is a device capable of reading and diagnosing an acquired image by x-raying an object and obtaining an image of an affected part of the object.

As an example of such an X-ray medical diagnostic apparatus, a medical diagnostic apparatus 90 as shown in FIG. 9 has been proposed. The diagnosing device 90 includes a lifting unit 91 having a built-in lifting actuator, which can be lifted up and down, on the device body 96, and is movable on one side of the lifting unit 91 via an arm 93. An X-ray generator 92 is provided, and an X-ray detector 94 is provided on the other side of the elevating portion 91 via a C-type arm 95.

The X-ray generator 92 and the detector 94 are disposed to face each other with respect to the elevating unit, and the arms 93 and 95 are rotatably installed with respect to the elevating unit. In use, not only X-ray imaging can be performed while the patient is standing, but the patient is very uncomfortable. X-ray imaging is made possible by passing through and is configured to photograph at various angles without moving the diagnostic device or moving the patient.

Meanwhile, the X-ray imaging apparatus should secure a SID (distance of the source for the image), which is the distance from the X-ray source to the detector, within a predetermined range, and the SID should generally secure 1000 to 1800 mm. 1800mm should be secured when the patient is standing up (horizontal photography) and 1000mm should be taken when the patient is lying down (vertical photography).

In the conventional diagnostic device 90, the distance from the central axis of the device body to the C-type arm is approximately 1000 mm, and the arm should be at least 800 mm or more, in order to ensure the maximum SID in horizontal imaging. SID in the photographing is up to 1000mm and the lowest point of the lifting portion should be secured while the maximum distance of lifting should be secured approximately 1300mm. In addition, the C-type arm in the conventional diagnostic device 90 has a fixed length and is not movable.

As shown in Fig. 9B, the conventional diagnostic device 90 has a height of at least 2.2 m and the main body of the device has a height of at least 2.2 m. The distance to the end of the arm will be at least 2.5m or more.

However, in general, since the ceiling height of the building is 2.5 m or less, there is a problem that it is difficult to use the conventional diagnostic apparatus installed in a building of a general floor. In addition, when adjusting the length of the C-type arm, the device main body, and the length of the arm so as to be suitable for the building of the general height, there is a problem that it is difficult to embrace the maximum value of the SID when the patient is photographed while standing. .

Therefore, there is a demand for a diagnostic apparatus capable of securing a maximum SID in horizontal imaging while being able to be sufficiently installed even in a building of a general floor height.

The present invention is to solve the above-mentioned problems of the prior art, by replacing the conventional C-type arm of the conventional diagnostic device to form a U-arm that can be adjusted in length to meet the maximum SID, but also fully installed in the building having a general height It is an object of the present invention to provide a medical diagnostic device that can be used.

In addition, another object of the present invention, while increasing the maximum movable distance of the lifting unit than the conventional diagnostic device, the length of the device body can be further reduced, and the length of the arm connected to the device body and the X-ray generator further It is to provide a medical diagnostic device that can be reduced.
