Abstract

PURPOSE:To make it possible to improve operability by fixing a member positioned from the direction of a winding-up mechanism to a hanged substance and providing a signal actuating the hung substance with a fixing member set approximately upper part and with a fixing member positioned approximately at roughly opposite side of a supporting pole and set approximately at an intermediate part. CONSTITUTION:An X-ray unit 12, a hung substance, is moved upward and downward against a winding-up mechanism 11 by an operation of an operator and is rotatable to a horizontal face or a vertical face and a cable 1, which is a member providing a signal actuating it, is placed from the direction of the winding-up mechanism to the unit. The cable is fixed with an upper clamp 2a for fixing set on the right end of the winding-up mechanism and an intermediate clamp 2b set on the left end of the X-ray tube unit positioned approximately at an opposite side of a supporting pole 14 against this. The cable between both clamps are passed through the rear side of the supporting pole. When the units moved upward, the cable is accordingly moved upward, but as both clamps are positioned in the opposite direction each other, slackening is also produced in the opposite direction and an enough space can be ensured. Furthermore, interference between the cables each other or the cable and the unit can be avoided and the operability is improved.

Description

[Detailed Description of the Invention] [Purpose of the Invention (Industrial Application Field) The present invention provides a method for holding a hanging object, for example, for X-ray fluoroscopy, on a hoisting mechanism via a rope and a support. The present invention relates to an X-ray holding device in which a hanging object can be moved up and down with respect to the hoisting mechanism by an operator's operation, and can be rotated about a horizontal axis or a vertical axis.

(Prior art) An X-ray diagnostic device uses an X-ray tube or other
It is equipped with an imaging system such as a radiation source system and a spot device that photographs the X-rays that have passed through the victim on an X-ray film. Also, as a fluoroscopic system, there is an image intensifier (hereinafter referred to as 1.I.) that detects the X-rays that have passed through the subject, and this I.I. I. It is equipped with a TV camera that converts the optical image from the TV camera into an electrical signal, and a TV monitor that displays the transparent image converted into the electrical signal from the TV camera.

That is, according to this X-ray diagnostic apparatus, the X-rays emitted from the X-ray tube and transmitted through the subject are I. I. The optical image is converted into an optical image by a TV camera and displayed as a transparent image on a TV monitor. Next, the operator irradiates the patient with a relatively large amount of X-rays from the X-ray tube while watching the TV monitor, and an X-ray image is captured on the X-ray film of the spot device.

By the way, in the X-ray diagnostic apparatus, for example, the X-ray
It is equipped with an X-ray holding device for holding and winding up the ray tube.

FIG. 4 is a schematic configuration diagram showing an example of this type of ceiling-type X-ray holding device. In the figure, the X-ray holding device includes a hoisting mechanism 11 (also referred to as a body) that is attached to a ceiling (not shown) and hoists an X-ray tube unit 12 having an X-ray tube 12a and an X-ray movable aperture 12b; 11 and an X-ray tube unit 12 as a hanging object, the support 14 is comprised of a plurality of cylindrical supports 14a to 14d having different diameters. The hoisting mechanism 11 includes a hoisting spring (not shown) inside. Equipped with booley.

In addition, the X-ray tube unit 12 is connected to the winding and mechanism 11 via a suspension wire rope (not shown) provided inside the column 14.
is maintained.

On the other hand, a cable 1 containing a built-in signal line for issuing an X-ray exposure command for X-ray photography is arranged from the right end of the hoisting mechanism 11 to the right end of the support column 14 to the X-ray unit 12. The cable 1 has its upper part fixed to the right end of the hoisting mechanism 11 with an upper clamp 2a, and its middle part fixed to the right end of the hoisting mechanism 11 with an intermediate clamp 2b.
It is fixed to the right end of the support column 14b and released.

Furthermore, the X-ray tube unit 12 has a vertical stroke of approximately 15 mm.
0 cm, and rotates about 360 degrees in the horizontal plane X and vertical plane Y. Therefore, the length of the cable 1 and the clamp ridge position are determined so that the X-ray tube unit 12 can rotate about the horizontal axis X and the vertical axis Y at the lowest vertical stroke position.

Therefore, as shown in FIG. 4(b), the upper clamp 2
A slack 3a for vertical movement stroke is provided between a and the intermediate clamp 2b.

Furthermore, a slack 3b is provided between the intermediate clamp 2b and the X-ray tube unit 12, which is a slack for rotating the X-ray tube unit 12 and a slack for moving the X-ray tube unit 12 upward. There is.

In the device configured in this manner, when the operator grasps the X-ray tube unit 12° and applies force upward, this force causes the X-ray tube unit 12, the struts 14d and 14c to be hoisted up in sequence to the side 11 of the hoisting machine. and can be moved upwards. In addition, by rotating the X-ray tube unit 12 to the horizontal plane X or the vertical plane Y by the operator's operation,
The radiation tube unit 12 is set at an appropriate position, and various images are taken of a subject (not shown).

(Problems to be Solved by the Invention) However, the above-mentioned conventional X-ray holding device has the following problems. That is, when the X-ray unit 12 is moved to a high position and the cable 1 is handled only on one side of the support column 14 as shown in FIG. 5, the cables will interfere with each other because of the slack 3a and 3b. Alternatively, the X-ray tube unit 12 and cable 1 may interfere with each other. Therefore, there was a problem in that the operability of the device deteriorated.

SUMMARY OF THE INVENTION An object of the present invention is to provide an X-ray holding device that can improve operability without interference between cables or between cables and hanging objects.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above problems and achieve the objects, the present invention takes the following measures. That is, in the present invention, a hanging object for X-ray fluoroscopic imaging is held in a hoisting mechanism via a rope and a support, and this hanging object can be moved up and down with respect to the hoisting mechanism by an operator's operation, and can be moved up and down on a horizontal plane. Alternatively, in an X-ray holding device that can rotate with respect to a vertical plane, a first fixing member provided on the road includes a member arranged from the direction of the hoisting mechanism to the hanging object and providing a signal to operate the hanging object. and a second fixing member disposed substantially on the opposite side of the support column to the first fixing member and provided at a substantially intermediate portion thereof.

(Effects) By taking such measures, the following effects will be exhibited. When the hanging object is moved, for example, upwardly relative to the hoisting mechanism by the operator's operation, the member also moves upwardly, but the first fixing member and the second fixing member are arranged in opposite directions. Therefore, the slack due to these also occurs in the opposite direction.

As a result, sufficient space can be secured, and interference between members or between members and hanging objects can be avoided, and operability can be improved.

(Example) Fig. 1 is a schematic configuration diagram showing an embodiment of the X-ray holding device according to the present invention, Fig. 2 is a top view of the X-ray holding device shown in Fig. 1, and Fig. 3 is a schematic diagram showing an embodiment of the X-ray holding device according to the present invention. It is a schematic diagram for explaining the effect of. Note that the same parts as those shown in FIGS. 4 and 5 are designated by the same reference numerals, and the details thereof will be omitted.

The X-ray holding device is, for example, a ceiling-type X-ray holding device, and is configured as follows.

The X-ray unit 12 as a hanging object can be moved up and down with respect to the hoisting mechanism 11 by the operator's operation, and can be rotated with respect to the horizontal plane X or the vertical plane Y. A cable 1 serving as a member for providing a signal for operating the X-ray unit 12 is arranged from the direction of the hoisting mechanism 11 to the X-ray unit 12.

The cable 1 also includes an upper clamp 2a as a first fixing member provided on the road, that is, at the right end of the hoisting mechanism 11, and an approximately intermediate portion disposed on the opposite side of the upper clamp 2a with the support 14 in between. That is, it is fixed by an intermediate clamp 2b as a second fixing member provided at the left end of the X-ray tube unit 12. A cable between the upper clamp 2a and the intermediate clamp 2b is passed through the rear side of the support column 14.

The operation of the device configured in this way will be explained. First, the operator grasps the X-ray tube unit 12 and applies an upward force, for example. When the X-ray tube unit 12 is moved upward by this force, it is in the intermediate position as shown by the dotted line in FIGS. 1 and 3. Clamp 2b and cable 1 move. Then, a slack 3C between the upper clamp 2a and the intermediate clamp 2b and a slack 3d between the intermediate clamp 2b and the X-ray tube unit 12 occur in substantially opposite directions with the support 14 in between.

That is, according to this, since the upper clamp 2a and the intermediate clamp 2b can secure enough space for the slack of the cable 1 at the upper part of the stroke, the slack of the cable 1 can be reduced by 3.
c and 3d are pillars] 4 and the X-ray tube unit 12. Also, the cables 1 will not interfere with each other.

According to this embodiment, the upper clamp 2a and the intermediate clamp 2b are arranged in opposite directions, so that the cables 1 can be connected to each other, or the cable 1 and the X-ray tube unit 1 can be
Interference with 2 can be avoided. This allows the X-ray unit 12 to be positioned easily and quickly.
Operability can be improved. Furthermore, since there is no interference between the cables 1 or between the cables 1 and the X-ray tube unit 12, the operating burden on the operator can be reduced. When the X-ray unit 12 is placed at a high position, the interference of the cable 1 is eliminated, so that no reaction force is applied by the cable 1, and the accuracy of positioning is improved.

Note that the present invention is not limited to the embodiments described above. In the above embodiment, the X-ray tube unit 12 is used as the hanging object, but the hanging object may also be an image intensifier, for example. Furthermore, in the embodiment described above, the upper clamp 2a is fixed to the right end of the hoisting mechanism 11, and the intermediate clamp 2b is arranged in the opposite direction to the upper clamp 2a, but even if these positional relationships are reversed, the above-mentioned effect can be obtained. A similar effect can be obtained. It goes without saying that various other modifications can be made without departing from the gist of the present invention.

[Effects of the Invention] According to the present invention, a member disposed from the direction of the hoisting mechanism to the hanging object for giving a signal to operate the hanging object,
Since the vehicle is fixed by a first fixing member provided on the road and a second fixing member provided substantially in the middle and located on the opposite side of the first fixing member across the pillar,
Since the first fixing member and the second fixing member are arranged in opposite directions, sag occurs in opposite directions. Therefore, since a sufficient space can be secured, interference between members or between members and hanging objects can be avoided, and an X-ray holding device with improved operability can be provided.
