Description

[Detailed Description of the Invention] [Purpose of the Invention (Industrial Field of Application) The present invention provides a system for moving the device itself toward the patient and positioning it at a desired position when the patient cannot be moved during surgery or the like. In order to be able to place the X-ray generating section and the image collecting section, the main body of the device is mounted on a trolley equipped with a steering mechanism, and has an operation panel on the top. The present invention also relates to a mobile X-ray diagnostic apparatus including a movable C-arm system having an image acquisition section, and particularly relates to a mobile X-ray diagnostic apparatus with improved steering operation.

(Prior Art) An example of this type of mobile X-ray diagnostic apparatus will be described with reference to FIG. 3. That is, swivel casters 1b are provided at the ends of the vertical member 1al of the approximately T-shaped base 1a of the truck 1, and steering casters 1cl,
1 c2 is provided.

Further, a device main body 2 having an operation panel 2a provided on the top is mounted on the trolley 1. The device main body 2 has various devices built into it, including a steering mechanism, a controller for setting X-ray conditions, etc., and the control panel and other devices are electrically connected.

Further, a push handle 2b for moving the device forward and backward is provided on the upper wall surface of the device main body 2 on the near side (the side where the operator is located). Furthermore, on the other side of the device main body 2 (the side opposite to the side where the surgeon is located), a C-arm drive mechanism 3 is provided.
is provided. This C-arm drive mechanism 3 includes X-ray generators 4a and I.

(2) A C-arm system 4 having a TV video device Z4b, a C7-arm 4C, and a C7-arm support 4d is movably provided. Furthermore, a rotary handle 2c for driving the steering mechanism is provided at the upper part of the front side of the main body 2 of the apparatus.

Next, referring to FIG. 4, the steering casters lcl, 1 of the bogie 1
The relationship between c2, the steering mechanism 5, and the rotary handle 2C will be explained. That is, as shown in FIG.
The rotation of is transmitted to the sprockets 5cl, 5c2 on both sides by the sprocket 5as chain 5b, and the rotation of the sprockets 5cl, ! is transmitted to the sprockets 5cl, 5c2 on both sides. l> The rotation of c2 is 5dl of its shaft.

It is transmitted to sprockets 5gl and 5g2 via 1.5f2. Steering caster IC by rotation of sprockets 5gl and 5g2! .

1c2 rotates, and the operation of the rotating handle 2C can be transmitted.

The operation in the above configuration is as follows. That is, consider a case where, for example, a subject is placed on a bed in an operating room, and it is desired to perform fluoroscopic imaging of, for example, the neck without moving the subject while proceeding with the surgery.

The operator rotates the rotary handle 2C with, for example, the right hand to steer the direction of movement of the apparatus, and pushes the push handle 2b with, for example, the left hand to bring the apparatus closer to a certain position of the subject. here,
The position of the C-arm system 4 is adjusted so that the subject's neck is aligned with the X-ray generator 4a and 1.1. and the attached TV video device 4b.

Then, the operator operates and sets the operation panel 2a to perform X-ray fluoroscopic imaging, and uses this fluoroscopic image or photographed image to assist in the progress of the surgery. In this case, as the surgery progresses, when it is desired to image a different region, the operator turns the rotary handle 2c again with, for example, the right hand to steer the direction of movement of the device, and pushes the push handle 2b with, for example, the left hand to obtain the desired image. Move the device closer to the location.

As described above, according to the configuration shown in FIGS. 3 and 4,
When it becomes necessary to move the position of the device, the device can be moved to the desired position by simply turning the rotary handle 2c with, for example, the right hand to steer the direction of movement of the device, and pushing the push handle 2b with, for example, the left hand. It's accessible and convenient. However, this means that when it becomes necessary to image a plurality of different regions during surgery, the device must be moved using both hands each time, which poses the following problem.

That is, since the operator (doctor) also moves the device and performs surgery on the subject, the rotary handle 2c, push handle 2b, etc. that the operator directly touches need to be sterilized. Therefore, the rotary handle 2c and the push handle 2b are carefully sterilized before or during surgery, and sterilized covers are attached to them. Sterilizing multiple areas like this is not a problem when there is plenty of time, but when an emergency patient is brought in and an emergency surgery is required, the areas that must be sterilized must be sterilized. Because there are multiple types, the sterilization process takes a long time,
It was a problem.

Furthermore, since the rotary handle 2d is provided near the operation panel 2a, the rotary handle 2d obstructs operations and settings for X-ray fluoroscopic imaging, which is a problem.

(Problems to be Solved by the Invention) As described above, in the conventional technology, when moving the device, it is possible to easily move the device by operating the rotating handle or push handle using both hands. However, since the rotary handle and push handle are parts that are directly touched by the surgeon, they must be sterilized. Since there are a plurality of parts to be sterilized in this way, the sterilization operation takes a long time, which is a problem.

Furthermore, the rotary handle obstructs operations and settings for X-ray fluoroscopic imaging, which is a problem.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a mobile X-ray diagnostic apparatus that reduces the time required for sterilization and allows convenient operation and settings for X-ray fluoroscopic imaging.

[Structure of the Invention] (Means for Solving the Problems) The present invention has a structure in which the following means are taken to solve the above problems and achieve the objects.

That is, in the present invention, an apparatus main body with an operation panel provided on the upper part is mounted on a cart equipped with a steering mechanism, and a C-arm system having an X-ray generating section and an image collecting section is mounted on the upper part of the apparatus main body. The movable X-ray diagnostic apparatus is characterized in that a foot-operated pedal is provided on the cart, and a mechanism is provided for transmitting rotation of the foot-operated pedal to the steering mechanism.

(Function) According to such a configuration, the direction of movement of the device can be set by operating the foot pedal with the foot, and the device can be easily moved without using both hands. Therefore, when moving the device, the number of parts that the operator touches directly is one fewer than in the past, and there is only one part to be sterilized, which is advantageous because the time required for sterilization work is shortened. In addition, the foot pedal, which is a member used by the operator to perform steering operations, is installed on the trolley, which is located far away from the operation panel operated during X-ray fluoroscopy. It does not interfere with the settings.

(Example) An example of the mobile X-ray diagnostic device according to the present invention will be described below.
Parts that are the same as those in Figures 3 and 4 are designated by the same reference numerals.
This will be explained with reference to the figures.

As shown in FIG. 1, in the mobile X-ray diagnostic apparatus of this embodiment, foot pedals 6a1 and 6a2 are provided on both sides of a portion of the trolley 1 directly below the installation of the apparatus main body 2. A steering mechanism 6 including the foot pedals 6 at and 6 a2 is built into the truck 1. And foot pedals 6 at, 6

Further, the shaft 6b is provided with a first bevel gear 6c,
The second bevel gear 6 is meshed with the first bevel gear 6c.
d is provided. This second bevel gear 6d is provided with a sprocket Be. Therefore, shaft 6
The rotation of b in the α direction shown in the figure is transmitted as the rotation of the sprocket 6e in the β direction shown in the figure.

Furthermore, a chain 6f is wrapped around the sprocket 6e, and this chain 6f is attached to the steering casters 1 cl , 1
Sprocket 6gl installed on c2.

It is also applied to 6g2.

In addition, as shown in FIG. 2, the steering casters la of the truck 1
A stopper 7 is provided adjacent to l. This stopper 7 is provided with a hemisphere 7b at the end opposite to the fixed side of a leaf spring 7a with one end fixed, and a hole 7C is formed in the steering caster lal so as to correspond to the hemisphere 7b and to fix the steering caster lal in a position where it moves straight. It has a set configuration.

The operation of this embodiment configured as described above is shown in FIGS. 1 and 3.
This will be explained with reference to the figures. For example, consider a case where a subject is placed on a bed in an operating room and it is desired to perform fluoroscopic imaging of, for example, the neck without moving the subject while proceeding with the surgery. That is, the operator operates the push handle 2 while steering the direction of movement of the device by operating the foot pedals 6a1 and 6a2 with his/her feet.
For example, press b with your left hand to bring the device closer to a certain position on the subject. Here, the position of the C-arm system 4 is adjusted so that the subject's neck is aligned with the X-ray generator 4a and 1. I, TV video device 4

In the above, the operator directly touches the push handle 2.
Since only b is used, the time required for sterilization treatment is short, which is advantageous.

In addition, the foot pedals 6al and 6a2, which are members for the operator to perform steering operations, are provided on the trolley 1, which is located far away from the operation panel 2a that is operated in X-ray fluoroscopic imaging. This is advantageous because it does not interfere with operations and settings during fluoroscopic imaging.

In addition, according to this embodiment, since there is no steering member (rotary handle 2c in the conventional example) on the operation panel 2a, the functions of the operation panel 2a can be increased by this extra space. There are advantages such as increased flexibility in the layout of switches and the like.

Furthermore, by operating the foot pedals 6al and 6a2 to insert the hemisphere 7b at the opposite end of the leaf spring 7a of the stopper 7 into the hole 7c of the steering caster lal,
Advantageously, the steering casters lal are fixed and allow the device to move in a straight line.

The present invention is not limited to the above embodiments, and for example, the truck 1 may have a configuration in which the front wheel is a steering caster and the rear wheel is a swivel caster, and of course, a truck other than three wheels may be used. It does not specify its composition. Further, in the above embodiment, the two steering casters are configured to be steered in conjunction with each other, but they may be configured to be able to be steered independently. Furthermore, there may be only one foot-operated pedal, and it may be mounted at the bottom where it can be operated with the foot. Further, as for the mechanism for transmitting the rotation of the foot pedal to the steering caster, various mechanisms other than the above-mentioned configuration using bevel gears, sprockets, and chains can be adopted.

The present invention may be modified in various ways without departing from the spirit of the invention.

[Effects of the Invention] As described above, in the present invention, a foot-operated pedal is provided on the trolley, and a mechanism for transmitting the rotation of the foot-operated pedal to the steering mechanism is provided, so that when the device is moved, the direction of movement of the device can be controlled. Settings can be made by operating the foot pedal with the foot, and the device can be easily moved without using both hands.

Therefore, when moving the device, the number of parts that the surgeon touches directly is one fewer than in the past, and there is only one part to be sterilized, so the time required for sterilization work is shortened.
It will be advantageous.

In addition, the foot pedal, which is a member used by the operator to perform steering operations, is installed on the trolley, which is located far away from the operation panel operated during X-ray fluoroscopy. It does not interfere with the settings.

Therefore, according to the present invention, it is possible to provide a mobile X-ray diagnostic apparatus that reduces the time required for sterilization and allows convenient operation and settings for X-ray fluoroscopic imaging.
