The present invention relates to a wire device.

[0002]

2. Description of the Related Art In a conventional mobile X-ray apparatus, a foot brake mechanism operated by stepping on a foot is used as a brake mechanism for stopping the apparatus. An example is shown in FIG. This device has a C-shaped arm 3 for holding an X-ray generating unit 1 and an X-ray receiving unit 2 facing each other, and the C-arm 3 is mounted on an X-ray control unit 5 via a support 4. It is. The X-ray control unit 5 is installed on a movable trolley 6, and is configured to be movable by rear wheels 7a and 7b serving as drive wheels and a front wheel 8 for controlling the direction.

Here, the brake mechanism is operated by depressing the foot lever 21 and pressing the stopper 22 against the floor. The foot lever 21 is supported by the rotating shaft 23 below the X-ray controller 5 and protrudes to both sides. This rotating shaft 23
Is mounted with a cam 24, and an end of the cam 24 is connected to one end of the connection plate 25. The connecting plate 25 has a stopper 22 at the other end.
Is provided, and is configured to be rotatable around a fulcrum 26 of the intermediate portion. As shown in FIG. 4, a tension spring 27 is mounted on the other end side (stopper 22 side) of the connecting plate 25,
Is kept out of contact with the floor surface. Foot lever 21
, The end of the cam 24 is pulled up in the figure, and accordingly, one end of the connecting plate 25 is also pulled up. As a result, the other end of the connecting plate 25 is pushed down, and the stopper 22 is pressed against the floor surface to act on the brake.

[0004]

However, in the above device, the foot lever protrudes to the side of the device, and the width of the entire device is increased. Therefore, when used in a small operating room, there is a drawback that a protruding foot lever hinders movement.

[0005] In addition, in order to move in a hospital or operate in a clean area such as an operating room, the operator often uses slippers or other easy-to-wear shoes. When the apparatus is stopped, the firm foot lever must be depressed with the slippers or the like, which makes the operation unpredictable, and there is a need to reliably perform the brake operation.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a mobile X-ray apparatus having a brake mechanism which can be reliably operated by hand, not by foot, and does not hinder the movement of the apparatus.

[0007]

The present invention achieves the above object by manually operating a brake mechanism.

That is, in the mobile X-ray apparatus according to the present invention, an X-ray generation unit, an X-ray image receiving unit, and a C-type device that holds these units in opposition to each other.
A mobile X-ray apparatus comprising a mold arm, a support for holding the C-arm so as to move in an arc with the center of the arc as a base point, and a movable carriage on which the support is mounted. A brake mechanism for braking and a hand lever for manually operating the brake mechanism are provided.

By using a hand lever instead of a foot lever, a reliable and quick brake operation can be performed manually. The hand lever is preferably provided on a surface other than the side surface of the device, for example, on the upper surface or the rear surface. By providing the hand lever on a portion other than the side surface, a wide space can be secured at the foot of the operator without increasing the width of the device, and the hand lever can be prevented from hindering movement.

It is desirable that the hand lever be rotatable so as to indicate braking / releasing depending on the operation angle. Since the angle of the hand lever is different between when the brake is braked and when the brake is released, it is possible to check at a glance whether the brake is operating.

The structure of the brake mechanism is not particularly limited as long as the movable carriage itself can be stopped. In addition to the configuration in which the brake pad is pressed against the wheel itself of the movable trolley, the configuration in which the stopper is pressed against the floor surface can be used. Normally, the brake mechanism is provided on the driving wheel itself of the movable cart or in the vicinity thereof.

[0012] Between the hand lever and the brake mechanism,
Generally, a power transmission means for transmitting the operation of the hand lever to the operation of the brake mechanism is interposed. The power transmission means includes a wire, a link, a cam, a gear, or a combination thereof.

[0013]

Embodiments of the present invention will be described below. FIG. 1 is a schematic view of a mobile X-ray apparatus according to the present invention.

This apparatus has a C-shaped arm 3 for holding an X-ray generating unit 1 and an X-ray image receiving unit 2 facing each other, and this C-arm 3 is connected to an X-ray control unit 5 via a support 4. It is a configuration that is mounted. The X-ray control unit 5 is installed on a movable trolley 6, and is configured to be movable by rear wheels 7a and 7b serving as drive wheels and a front wheel 8 for controlling the direction.

The X-ray generator 1 includes an X-ray tube device for generating and irradiating X-rays, a movable diaphragm for limiting the X-ray irradiation range,
And a high-voltage device that applies a high voltage to the X-ray tube device to generate X-rays. The X-ray receiving unit 2 includes an image intensifier that converts an X-ray transmitted through the subject into an optical image, and an X-ray TV camera that converts the optical image into a video signal.

The C-shaped arm 3 is held by a supporting portion so as to move in an arc from the center of the arc. Support
Numeral 4 is attached to the X-ray controller 5 so as to be rotatable about a vertical axis as a rotation axis.

The moving carriage 6 includes a hand lever 10 and a handle 1
It has rear wheels 7a, 7b for the operator to push and move 1 and a front wheel 8 that rotates 360 ° about a vertical axis as a rotation axis. A stopper 9 as a brake mechanism is provided near each of the rear wheels 7a and 7b.

Here, the brake mechanism is operated by rotating the hand lever 10 and pressing the stopper 9 against the floor. In this example, the hand lever 10 is installed at a corner on the upper surface of the X-ray controller 5. A moving operation handle 11 is provided at a position symmetrical to the hand lever 10, and the hand lever 10 is provided.
10 has the same shape as the moving operation handle 11. When stopped, the hand lever 10 functions as a brake operation lever, and when traveling, the hand lever 10 functions as a handle that facilitates the operation of moving the movable carriage 6 by holding it together with the movement operation handle 11. The function of the brake is to prevent the mobile X-ray apparatus that has been stopped from moving unexpectedly.

The hand lever 10 has a shaft drum 12
Are connected to the two wires 13 via. When the lever 10 is rotated, the shaft drum 12 rotates, and each wire 13 can be pulled or returned. The stopper 9 is connected to the tip of each wire 13. The stopper 9 is configured to be constantly pressed downward (on the floor side) by the compression spring 14.

The operation of such a brake mechanism will be described with reference to FIG. At the time of non-braking, the hand lever 10 is directed to the rear of the movable trolley 6 as shown by a solid line.

During braking, once the hand lever 10 is pulled up,
Make it rotatable. Hold the hand lever 10 as it is about 18
It turns by 0 ° and returns to the position before the lifting after moving toward the front of the movable cart 6 (indicated by a broken line). The rotation angle of the hand lever 10 is not particularly limited. As shown in FIG. 1, the rotation range may be 90 °. The shaft drum 12 rotates in conjunction with the rotation of the hand lever 10, and the wire 13 is pulled out to stop the stopper 9.
Is pressed against the floor. Needless to say, the rotation range can be set to 45 ° or various values.

To release the brake mechanism, the hand lever 10 is turned in the opposite direction to the above, the wire 13 is pulled back, and the stopper 9 is pulled up from the floor.

As described above, by manually rotating the hand lever 10, the brake mechanism can be reliably operated. Further, it is possible to determine at a glance whether braking or non-braking is performed based on the direction of the hand lever 10.

In the above embodiment, the connection between the hand lever and the stopper is made by a wire, but this wire can be replaced by another power transmission means such as a link. Although the brake mechanism is provided near the rear wheel, it may be provided near the front wheel. Further, instead of the brake mechanism for pressing the stopper against the floor, a brake mechanism for pressing the brake pad against the front wheel or the rear wheel itself may be used.
