Description

[Detailed description of the invention] (a) Industrial application field The present invention is used in the field of medical machine auxiliary equipment and cable processing equipment.

The present invention relates to a suspended C-arm holding device, and more particularly to a suspended C-arm holding device that travels on the ceiling and is used in medical X-ray fluoroscopy and cine imaging equipment, and in particular, an improved suspended C-arm holding device having a cable handling function. Regarding.

(B) Prior Art In conventional medical X-ray fluoroscopic equipment, high voltage cables for generating X-rays and transmission cables for transmitting images and control signals from the image receiving device are fixed at appropriate positions on the equipment.

(c) Problems to be solved by the invention Therefore, when this device is operated, the space necessary for the function or operation of the device is occupied by the cable due to the unpredictable movement of the connecting cable, which impairs the function and operation of the device. This adversely affects operability.

Furthermore, since the weight of the cable is added to the movable parts of the device, the force required to operate and drive the parts increases, resulting in poor operability.

Additionally, cable slack, which is set to account for the amount of device actuation, causes the cable to come into contact with undesirable locations (eg, the floor or the operator).

The purpose of this invention is to prevent the cable from occupying space necessary for the function and operation of the device as the device moves, reduce the force required for operation and drive, and prevent the cable from coming into contact with undesirable locations. An object of the present invention is to provide a suspended C-arm holding device.

(d) Means for solving the problem The above purpose is to develop a suspended C-arm equipped with a column that rotatably holds the C-arm, which is connected to an X-ray tube at one end and an image receiving device at the other end. In the holding device, this is achieved by providing a spring balancer at the top of the support to carry the weight of the cable connected to the X-ray tube, and a roller to guide the cable at the bottom of the support. .

(E) Function A spring balancer and a roller are attached to the support of the suspended C-arm holding device, and the high voltage generator, X
The weight of the cable connected between the X-ray tubes is carried by a spring balancer, and the cable near the X-ray tube is guided by rollers, so there is little change in the C-arm center of gravity position during C-arm rotation, and C-arm movement is minimized. The cable is fed out and stored in accordance with the movement of the cable, making manual operation easy.

(F) Embodiments A preferred embodiment of the present invention will be explained based on the drawings.

The drawing is a front view of essential parts of a ceiling suspended type with a C-arm, showing one embodiment thereof.

In the drawing, 10 is a C-arm, 12 is an image receptor fixed to one end thereof, 14 is an X-ray tube fixed to the other end, 16 is a column, 18 is a spring balancer, 20 is a roller, and 22 is connected to a spring balancer. The looped wire 24 is the cable in question. Note that 30 is a floor and 32 is a ceiling rail.

More specifically, the C-arm 10 rotates around a rotation center O, and includes an X-ray tube 14 and an image receiving device 12.

The spring balancer 18 has the function of always winding up the attached wire 22 with a constant force, and can also adjust the winding force.

Now, adjust the relationship between the winding force and the weight of the cable so that the winding force is slightly stronger, using the spring balancer 1.
Adjust 8.

Therefore, the C-arm 10 rotates around the rotation axis O.
When rotated in this direction, the cable 24 tends to sag due to its own weight.

However, according to this embodiment, this cable 2
4 is suspended from the spring balancer 18 via the roller 20 and the wire 22, so the cable 24
The slack is automatically lifted up by the action of the spring balancer 18 and the wire 22.

Conversely, the C-arm 10 rotates B around the rotation center O.
When rotating in this direction, the cable 24 that has been pulled up is let out in response to the movement of the C-arm 10.

In this way, following the movement of the C-arm 10,
As the cable 24 is stored, extended, and
There is no need to slacken the cable 24 in anticipation of the amount of movement of the arm 10, and operability is improved.

Further, since a constant tension is always applied to the cable 24 and the weight of the cable 24 is supported, the cable 24 does not come into contact with the floor.

Furthermore, since there is no friction with the floor surface, the force required for operation or drive can be reduced.

It also helps keep the cable clean.

In particular, in devices that manually operate the C-arm 10, the weight of the cable 24 affects the operating force, often resulting in poor operability.

In the present invention, since the weight of the cable 24 is almost balanced with the spring balancer, the influence of the weight of the cable on the operating force is small, and the operability is significantly improved.

(G) Effects According to the present invention, the cable does not land on the floor.
The slack is adjusted in the vertical direction at one point, which significantly improves operability by reducing the operating force and driving force of X-ray fluoroscopy and cine imaging equipment, and also maintains the cleanliness of the cable. be done.
