Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an X-ray protection plate.
[0002]
[Prior art]
In recent years, intervention treatment has been actively performed because treatment with higher QOL than surgical treatment can be performed. In interventional treatment, treatment and examination are performed using a plurality of medical instruments mainly having a catheter having a length of 150 to 180 cm.
[0003]
These medical instruments are usually placed on a work table installed in the vicinity of a patient, and an operator performs various operations on the table. The table used for such work is not conventionally developed especially for interventional treatment, and bedside tables (see, for example, Patent Documents 1 and 2) frequently used in hospitals and the like are used. [0004]

[Problems to be solved by the invention]
By the way, in interventional treatment, the patient's upper limb is opened about 15 degrees outward from the trunk, placed on a hand table that is in a position protruding from the operating table, and is used to move upward from below the operative field using an X-ray transmission device. The operator emits X-rays, and the surgeon looks at the X-ray image displayed on the monitor and performs diagnosis, examination, treatment, surgery, and the like. At this time, in order to prevent X-ray exposure, the surgeon wears various X-ray protective equipment such as X-ray protective clothing, a body protector for X-ray protection, a neck protector, a spectacle-type protector, and a glove-type protector. Yes.
[0006]
However, these conventional X-ray protective devices do not completely envelop the operator's body for convenience of wearing so as not to obstruct the operator's movement and visual field. Therefore, in the medical field, there is a demand for new means that can further enhance X-ray exposure prevention measures while being used in combination with conventional X-ray protective tools.
[0007]
The present invention has been completed to meet the above-mentioned demands, and the purpose of the present invention is to further enhance measures for preventing an operator's X-ray exposure when performing treatment and examination under fluoroscopy. It is to provide a line protection plates.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention adopts the following characteristic configuration.
The X-ray protection plate according to claim 1 is:
An X-ray protection plate mounted on the upper plate of the table used by installing in the vicinity of the patient in performing the treatment and examined under X-ray fluoroscopy,
A surface that is directed upward in a state of being installed on the deck is erected so as to protrude upward from a bottom portion used as a mounting surface for mounting a medical device, and a peripheral edge of the bottom portion. When the medical device is placed on the mounting surface, the medical device has a side wall portion that prevents the medical device from falling off from the periphery of the bottom portion, and the bottom portion and the side wall portion are X-rays. A plate body integrally molded with a protective material ;
It is a bracket bent in an L shape, and when the bent part is on the lower end side, it can be fixed to the outer peripheral side of the side wall of the plate body with a screwed part that is closer to the upper end than the bent part. When fixed, the portion on the opposite side of the screwed portion across the bent portion is arranged parallel to the bottom surface of the bottom portion, and the portion between the bottom surface of the bottom portion and the bottom portion L-shaped metal fittings that are the parts that sandwich the deck
With
By arbitrarily changing the mounting position of the L-shaped bracket to the plate body in the vertical direction in the state where it is installed on the deck, the L-shaped bracket is fixed to the plate body with screws. It can be attached to the deck of the thickness of
It is characterized by that.
[0009]
The X-ray protection plate according to claim 2 is :
Of the entire periphery of the bottom, the side wall is formed in a part of the range, and the side wall is not formed in the remaining part of the range.
[0011]
[Operation and Effect of Invention]
In the X-ray protection plate of the present invention , the X-ray protection material is not particularly limited as long as it is a material that can prevent transmission of X-rays.
As components capable of preventing X-ray transmission, for example, lead, gold, silver, copper, tungsten, molybdenum, barium, antimony, aluminum, bismuth, iron, strontium, iodine, silicon, and tantalum are known. Of these, heavy metal elements such as lead are desirable because they have a high shielding effect. These elements may be contained alone in the material as long as they are stable, or may be contained as oxides or other compounds. Moreover, these elements or their compounds may be used individually by 1 type, and 2 or more types may be mixed and used for them.
[0012]
Further, the X-ray protective material is a composition in which a component having the X-ray protective ability and a component having no X-ray protective ability are blended as long as the necessary X-ray protective ability can be secured. May be. For example, the above-described elemental element having X-ray protective ability or a compound thereof may be dispersed in a resin material having no X-ray protective ability. In this case, the moldability is improved and the weight is reduced. Since it can also be achieved, it is preferable.
[0013]
As such an X-ray protective material, for example, a material disclosed in Japanese Patent Publication No. 7-17817 is known.
As the resin material, a known thermoplastic resin or thermosetting resin can be arbitrarily used. For example, polyolefin resin, polystyrene resin, polyamide resin, polyester resin, aromatic polyester resin, vinyl resin. , Acrylic resin, polyurethane resin, fluorine resin, polyimide resin, silicone resin, polycarbonate resin, polyethersulfone resin, polyphenylene sulfide resin, polyetheretherketone resin, phenol resin, xylene resin, urea resin, Saturated polyester resins, alkyd resins, epoxy resins, furan resins, melamine resins, ABS resins and the like are suitable. In particular, it is desirable to use a resin material having high chemical resistance such as a fluorine-based resin from the viewpoint of preventing deterioration due to alcohol for disinfection and other chemicals.
[0014]
When the blending ratio of the resin material is large to some extent, the moldability is high, but if it is too much, the X-ray transmission amount tends to increase, but the X-ray transmission amount may vary depending on the thickness of the molded product. Since the intensity of X-rays emitted from the X-ray source can be changed, the blending ratio is appropriately adjusted in consideration of these points.
[0015]
X-ray protection plate of the present invention is formed by X-ray protection material as described above, mounted on the upper plate of the table used by installing in the vicinity of the patient in performing the treatment and examined under X-ray fluoroscopy Used. Specifically , the X-ray protection plate is placed on the deck, and both are fixed using L-shaped brackets and screws .
[0016]
Height of the deck tables is normally set at a height that can operate a medical device by hand in the left table surgeon standing, waist from the ventral position of deck generally surgeon It becomes around. In order to facilitate the setting of such a height position, it is preferable to use a table having a structure in which the height position of the portion corresponding to the deck can be adjusted up and down. Of course, a table with an appropriate height is used. If there is, it is not essential to be able to adjust the elevation.
[0017]
In the vicinity of such a table, when the X-ray transmission device emits X-rays from the lower side to the upper side of the operative field, the X-rays are emitted from the lower side to the upper side than the deck of the table. However, X-rays do not pass through the deck from bottom to top, and the upper body of the surgeon above the table deck is protected from X-rays compared to using a table through which X-rays pass. .
[0018]
Therefore, if this X-ray protection plate is used, X-ray exposure prevention measures can be further enhanced while being used in combination with conventional X-ray protection tools.
Further, the X-ray protection plate of the present invention is also characterized in that it has a shape having a side wall portion standing on the periphery of the bottom portion. If comprised in this way, it can prevent that a medical device falls out on a X-ray protection plate in a side wall part by mounting a medical device in the location corresponded to a bottom part.
[0019]
In particular, in the case of a long and elastic medical device such as a catheter, if it extends from the deck of the table by stretching due to its elasticity, it tends to cause problems such as slipping and fouling. If such a side wall portion is formed, the catheter can be prevented from extending by contacting the side wall portion by placing the catheter inside the side wall portion. In addition, even if the catheter protrudes from the X-ray protective plate in such a way as to get over the side wall, the catheter is difficult to slide in the direction of going up the side wall, so that the catheter may slip from the X-ray protective plate. Is prevented.
[0020]
Furthermore, the X-ray protection plate according to claim 2 is such that a side wall portion is formed in a part of the entire periphery of the bottom portion, and a side wall portion is not formed in the remaining part of the range. There is also a feature. If it is configured in this way, the equipment that you want to prevent from sliding down as described above should be used in such a way as to get over the side wall, while avoiding use in such a way as to get over the side wall. Since it can be used by the method of arrange | positioning in the place which does not have a side wall part about an instrument which wants to use, a usability becomes favorable rather than what provided the side wall part over the perimeter.
[0023]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described with an example.
FIG. 1 is a perspective view of an X-ray protection plate.
This X-ray protection plate 1 is shaped like a tray having a bottom 3 and a side wall 5 standing on the periphery of the bottom 3, and the overall size is 1050 mm long × 400 mm wide × 40 mm high, The thickness of the bottom part 3 and the side wall part 5 is 7 mm, and the bottom part 3 and the side wall part 5 are integrally formed. Further, an L-shaped metal fitting 7 and a screw 9 used for fixing the X-ray protection plate 1 to an attachment target are attached.
[0024]
The bottom 3 has a rectangular shape when viewed from above (in this embodiment, a rectangle of 1050 mm × 400 mm) with rounded corners (in this embodiment, a round that draws an arc with a radius of 50 mm). An article such as a medical instrument is placed thereon.
[0025]
The side wall portion 5 is erected on the periphery of the bottom portion 3, and the height of the side wall portion 5 is 40 mm, and the corner on the upper end side of the end of the side wall portion 5 is rounded (in this embodiment, the radius is 20 mm). (A round shape that draws an arc) is attached. Further, a screw hole 11 having a diameter of 5 mm is formed in the side wall portion 5 in order to screw the screw 9 therein. The side wall 5 is formed in a part of the entire periphery of the bottom 3, and the side wall 5 is not formed in the remaining part of the range. In addition, the range in which the side wall part 5 is not formed is a range extending over two sides including one corner of the rectangular bottom part 3.
[0026]
The bottom 3 and the side wall 5 are made of an X-ray protective material. In this embodiment, the X-ray protective material used to form the bottom portion 3 and the side wall portion 5 is an acrylic resin composite material containing 0.1 mm equivalent of lead as a component having an X-ray protective ability. Such an X-ray protective material has higher moldability than lead itself, and can form a molded product that is lighter than the same volume product made of lead. In addition, since it is lighter than lead, it is easier to attach and detach than a heavy lead product, and cleaning and other operations can be easily performed. Moreover, it is excellent in chemical resistance, and there is no problem even if alcohol for disinfection adheres.
[0027]
Note that the L-shaped metal fitting 7 has a long hole with a length of 14 mm. By passing a screw 9 through the long hole, the relative positional relationship between the L-shaped metal fitting 7 and the side wall portion 5 is slightly increased in the vertical direction. It can be adjusted.
As shown in FIG. 2, the X-ray protection plate 1 configured as described above is fixed to the table 15 using an L-shaped metal fitting 7 and a screw 9. The table 15 is a bedside table with a caster configured so that the height of the deck 17 can be adjusted. However, the table 15 itself is commercially available. Since it is disclosed, a detailed description of the structure of the table 15 is omitted.
[0028]
The table 15 to which such an X-ray protective plate 1 is attached is installed in the vicinity of the patient when performing treatment or examination under X-ray fluoroscopy, and the place on which various medical instruments are placed on the X-ray protective plate 1 Used as The height position of the deck 17 of the table 15 is set to such a height position that the medical instrument on the X-ray protection plate 1 can be operated by hand while the operator is standing. From the belly of the person around the waist. Therefore, even when the X-ray transmission device emits X-rays from the lower part of the operative field to the upper part, the X-rays cannot pass through the X-ray protection plate 1 on the deck 17 from the lower part to the upper part. In addition, the upper body of the surgeon above the deck 17 of the table 15 is protected from X-rays compared to the case where the table 15 without the X-ray protection plate 1 is used. Therefore, if this X-ray protection plate 1 is used, X-ray exposure prevention measures can be further enhanced while being used in combination with conventional X-ray protection tools.
[0029]
Further, since the X-ray protection plate 1 has a shape having a side wall portion 5 erected on the periphery of the bottom portion 3, when the catheter or the like is rolled up, the catheter is stretched by the elasticity of the catheter. Even so, since the catheter hits the side wall and does not extend any further, it becomes difficult for the catheter to fall off the X-ray protective plate 1. Further, even if the catheter protrudes from the X-ray protective plate 1 in such a way as to get over the side wall portion 5, the catheter does not slide in the direction of going up the side wall portion 5, so the catheter does not slide from the X-ray protective plate 1. It is prevented from falling. Therefore, it is possible to secure a suitable place for placing and operating instruments necessary for surgery, treatment, and examination.
[0030]
Further, in this X-ray protection plate 1, the side wall 5 is formed in a part of the entire periphery of the bottom 3, but the side wall 5 is not formed in the remaining part of the range. Therefore, it is possible to use an instrument that is desired to avoid being used in such a way as to get over the side wall part 5 by placing it in a place without the side wall part 5.
[0031]
As mentioned above, although embodiment of this invention was described, this invention is not limited to said specific one Embodiment, In addition, it can implement with a various form .
[0032]
Specifically, in the above-described embodiment, the X-ray protection plate 1 having a specific shape is illustrated, but the design of the shape of the details can be arbitrarily changed. For example, in the case of the above embodiment, the shape is substantially rectangular in plan view, but may be a shape other than a rectangle. Also, the height of the side wall portion 5 can be arbitrarily designed from a relatively low to a relatively high one as long as it does not interfere with the medical action of the operator. The range in which the side wall portion 5 is not provided is also arbitrary as long as it is a range in which surgery, treatment, and examination are easy.
[0033]
In addition, although not described in detail in the above embodiment, this type of X-ray protection plate 1 is used not only for interventional treatment but also for other treatment methods. It can be used in all operations, treatments and examinations using
