Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an X-ray protection plate.
[0002]
[Prior art]
In recent years, interventional treatments have been actively performed since treatments having a higher QOL than surgical treatments can be performed. In interventional treatment, treatment and examination are performed using a plurality of medical instruments mainly with a catheter having a length of 150 to 180 cm.
[0003]
These medical instruments are usually placed on a work table installed near a patient, and an operator performs various operations on the table. Conventionally, a table used for such an operation has not been developed especially for interventional treatment, and a bedside table (for example, see Patent Documents 1 and 2) frequently used in hospitals and the like is diverted. [0004]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 9-252850 [Patent Document 2]
JP-A-2002-58539
[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 handstand that is protruding from the operating table, and then, using an X-ray transmission apparatus, from below the operating field to above. X-rays are emitted toward the operator, and the operator performs diagnosis, examination, treatment, surgery, and the like while viewing the X-ray image displayed on the monitor. 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 torso protector for X-ray protection, a neck protector, an eyeglass-type protector, and a glove-type protector. I have.
[0006]
However, these conventional X-ray protective devices do not completely enclose the operator's body because they are worn so as not to obstruct the operator's movement and view. Therefore, in the medical field, there is a demand for a new means capable of further enhancing the measures for preventing X-ray exposure while using it together with the conventional X-ray protective equipment.
[0007]
The present invention has been completed in order to meet the above-mentioned demand, and an object of the present invention is to provide an X-ray which can further enhance measures for preventing an operator from being exposed to X-rays when performing treatment or examination under X-ray fluoroscopy. It is to provide a radiation protection plate and an X-ray protection table.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention employs the following characteristic configuration.
The X-ray protection plate according to claim 1,
A member used as a deck of a table that is installed and used in the vicinity of a patient when performing treatment or examination under X-ray fluoroscopy, or a member mounted on the deck of the table, and is made of an X-ray protective material. It is characterized by being formed.
[0009]
The X-ray protection plate according to the second aspect,
It has a bottom portion on which articles are placed, and a side wall portion erected on the periphery of the bottom portion.
The X-ray protection plate according to the third aspect,
The side wall portion is formed in a part of the entire periphery of the bottom portion, and the side wall portion is not formed in the remaining part of the periphery.
[0010]
The X-ray protection table according to the fourth aspect,
A table installed and used in the vicinity of a patient when performing treatment or examination under X-ray fluoroscopy, wherein the deck of the table or a member mounted on the deck of the table is made of an X-ray protective material. It is characterized by being formed.
[0011]
[Action and Effect of the Invention]
In the X-ray protection plate according to any one of claims 1 to 3, 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 transmission of X-rays, for example, lead, gold, silver, copper, tungsten, molybdenum, barium, antimony, aluminum, bismuth, iron, strontium, iodine, silicon, tantalum and the like are known. Of these, heavy metal elements such as lead are preferable because of their 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. These elements or compounds thereof may be used alone or in a combination of two or more.
[0012]
Further, the X-ray protection material is a composition containing the above-mentioned component having the X-ray protection capability and the component having no X-ray protection capability as long as the required X-ray protection capability can be secured. You may. For example, a simple substance of the element having the X-ray protection ability or a compound thereof may be dispersed in a resin material having no X-ray protection ability. In this case, the moldability is increased and the weight is reduced. It is preferable because it can also be used.
[0013]
As an X-ray protection material having such a configuration, for example, a material disclosed in Japanese Patent Publication No. 7-17817 is known.
As the resin material, a known thermoplastic resin or a thermosetting resin can be arbitrarily used. For example, a polyolefin resin, a polystyrene resin, a polyamide resin, a polyester resin, an aromatic polyester resin, a vinyl resin , Acrylic resin, polyurethane resin, fluorine resin, polyimide resin, silicone resin, polycarbonate resin, polyether sulfone resin, polyphenylene sulfide resin, polyether ether ketone resin, phenol resin, xylene resin, urea resin, Saturated polyester resins, alkyd resins, epoxy resins, furan resins, melamine resins, ABS resins and the like are preferred. In particular, it is desirable to use a resin material having high chemical resistance such as a fluorine-based resin in that deterioration due to disinfecting alcohol or other chemicals can be prevented.
[0014]
When the mixing ratio of the resin material is relatively large, the moldability increases. On the other hand, when the ratio is too large, the amount of X-ray transmission tends to increase. However, the amount of X-ray transmission may vary depending on the thickness of the molded product. Since the intensity of X-rays radiated from the X-ray source can vary, the mixing ratio is appropriately adjusted in consideration of these points.
[0015]
The X-ray protection plate of the present invention is formed of the above-mentioned X-ray protection material and is used as a deck of a table which is installed and used in the vicinity of a patient when performing treatment or examination under X-ray fluoroscopy. It is used by being mounted on the deck of a table. That is, when using the X-ray protection plate of the present invention as a deck of a table, replace the deck originally attached to the table with the X-ray protection plate of the present invention, or prepare only a support serving as a leg. A table is constructed by mounting the X-ray protection plate of the present invention on the support. When the X-ray protection plate of the present invention is used by being mounted on a deck of a table, the X-ray protection plate is overlaid on the deck, and both are fixed using screws or other fixing tools.
[0016]
In any case, the height of the deck of such a table is usually set so that the operator can operate the medical instruments on the table by hand while standing, and the position of the deck However, it is generally around the waist from the surgeon's belly. In order to facilitate the setting of such a height position, it is preferable to use a table having a structure capable of adjusting the height position of the portion corresponding to the deck, but of course, a table having an appropriate height is preferable. If so, it is not essential to be able to adjust the elevation.
[0017]
When the X-ray transmission apparatus emits X-rays from below the surgical field upward in the vicinity of such a table, the X-rays are emitted upward from below the deck of the table. However, the upper body of the operator above the deck of the table is protected from X-rays, compared to the case where the table does not allow X-rays to pass through the deck from the bottom up and X-rays are transmitted. .
[0018]
Therefore, if this X-ray protection plate is used, the measures for preventing X-ray exposure can be further enhanced while being used in combination with the conventional X-ray protection tool.
Further, the X-ray protection plate according to the second or third aspect is characterized in that the X-ray protection plate has a shape having a side wall portion erected on the periphery of the bottom. With this configuration, the medical device can be prevented from dropping off the X-ray protection plate at the side wall portion by placing the medical device on a portion corresponding to the bottom.
[0019]
In particular, in the case of a medical device such as a catheter that is long and elastic, if it protrudes from the deck of the table, for example, due to its elasticity, it easily slips and becomes dirty. If such a side wall portion is formed, the catheter can be placed inside the side wall portion so that the side wall portion abuts, thereby preventing the catheter from expanding. Also, even if the catheter protrudes from the X-ray protection plate over the side wall, it is difficult for the catheter to slide up the side wall, so the catheter may slip off the X-ray protection plate. Is prevented.
[0020]
Furthermore, the X-ray protection plate according to claim 3 is characterized in that a side wall is formed in a part of the entire periphery of the bottom, and a side wall is not formed in the remaining part. There is also a feature. With this configuration, as described above, the device that is desired to be prevented from sliding down 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. The desired device can be used in such a manner that it is disposed in a place without the side wall portion, so that it is more convenient to use than the device having the side wall portion all around.
[0021]
As is clear from the above description, the X-ray protection table according to claim 4 is a table that is installed and used near a patient when performing treatment or examination under X-ray fluoroscopy, Since the deck of the table or the member mounted on the deck of the table is formed of an X-ray protective material, the same as the X-ray protective plate according to any one of claims 1 to 3 above. Function and effect.
[0022]
In the X-ray protection table according to the fourth aspect, the deck of the table, or a member mounted on the deck of the table, is provided upright on the bottom on which articles are placed and on the periphery of the bottom. It is good to be made into the shape which has a side wall part. In this case, it is preferable that the side wall is formed in a part of the entire peripheral edge of the bottom, and the side wall is not formed in the remaining part of the periphery.
[0023]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with an example.
FIG. 1 is a perspective view of the X-ray protection plate.
This X-ray protection plate 1 is shaped like a tray having a bottom 3 and a side wall 5 erected on the periphery of the bottom 3, and has an overall size of 1050 mm long × 400 mm wide × 40 mm high. The bottom 3 and the side wall 5 have a thickness of 7 mm, and the bottom 3 and the side wall 5 are integrally formed. Further, an L-shaped bracket 7 and a screw 9 used for fixing the X-ray protection plate 1 to an object to be mounted are attached.
[0024]
The bottom 3 has a rectangular shape (a rectangular shape of 1050 mm × 400 mm in the present embodiment) with rounded corners (in the present embodiment, a circular arc with a radius of 50 mm) when viewed from above. An object such as a medical instrument is placed on the plate-shaped body.
[0025]
The side wall portion 5 is provided upright on the peripheral edge of the bottom portion 3. The height of the side wall portion 5 is 40 mm, and the upper end corner of the end of the side wall portion 5 is rounded (in the present embodiment, the radius is 20 mm). Rounded to draw an arc). Further, a screw hole 11 having a diameter of 5 mm is formed in the side wall portion 5 for screwing the screw 9. 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 periphery. The range in which the side wall 5 is not formed is a range extending over two sides including one corner of the rectangular bottom 3.
[0026]
The bottom 3 and the side wall 5 are made of an X-ray protective material. In the present embodiment, the X-ray protection material used to form the bottom portion 3 and the side wall portion 5 is an acrylic resin-based composite material containing 0.1 mm equivalent of lead as a component having X-ray protection capability. Such an X-ray protective material has higher moldability than lead itself, and can form a molded article that is lighter in weight than an equal volume product made of lead. Also, since it is lighter than lead, it can be easily attached and detached, and can be easily cleaned and worked as compared with heavy lead. In addition, they have excellent chemical resistance, and there is no problem even if alcohol for disinfection adheres.
[0027]
The L-shaped fitting 7 has a long hole with a length of 14 mm. By passing a screw 9 through this long hole, the relative positional relationship between the L-shaped fitting 7 and the side wall 5 is slightly changed in the vertical direction. It can be adjusted.
The X-ray protection plate 1 configured as described above is fixed to the table 15 using the L-shaped bracket 7 and the screw 9 as shown in FIG. The table 15 is a bedside table with casters configured so that the height of the deck 17 can be adjusted. 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 on which such an X-ray protection plate 1 is mounted is installed near a patient when performing treatment or examination under X-ray fluoroscopy, and the top of the X-ray protection plate 1 is a place where various medical instruments are placed. Used as The height position of the deck 17 of the table 15 is set to a height position at which the operator can manually operate the medical device on the X-ray protection plate 1 while standing, so that the position of the deck 17 is generally adjusted. From the belly of the person to the waist. Therefore, even when the X-ray transmission apparatus emits X-rays from below the surgical field to above, the X-rays do not pass through the X-ray protection plate 1 on the deck 17 from below to above. The upper body of the operator above the deck 17 of the table 15 is protected from X-rays as compared with 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, the X-ray exposure prevention measures can be further enhanced while being used in combination with the conventional X-ray protection tool.
[0029]
Further, since the X-ray protection plate 1 has a shape having a side wall 5 erected on the periphery of the bottom 3, when the catheter or the like is to be rolled and stored, the catheter is extended by the elasticity of the catheter. However, since the catheter hits the side wall and does not extend any further, it is difficult for the catheter to drop off from the X-ray protection plate 1. Further, even if the catheter protrudes from the X-ray protection plate 1 in such a way as to get over the side wall 5, the catheter does not easily slide in the direction going up the side wall 5, so that the catheter slips from the X-ray protection plate 1. Falling is prevented. Therefore, it is possible to secure a place suitable for placing instruments necessary for surgery, treatment, and examination, and for performing the operations.
[0030]
Further, in the 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. Therefore, a device that is desired to be avoided from being used over the side wall portion 5 can be used in such a manner that the device is disposed at a place where the side wall portion 5 does not exist.
[0031]
As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the above-described specific embodiment, and can be implemented in various other modes.
For example, in the above-described embodiment, an example in which the X-ray protection plate 1 is mounted on a commercially available table 15 and used is shown. Even if an X-ray protection table is configured, exactly the same operation and effect can be expected. In the above-described embodiment, the X-ray protection plate 1 is mounted on the deck 17 of the commercially available table 15, but if the deck can be removed, the X-ray protection plate having the same connection structure as the deck is provided. A table may be prepared by preparing a plate and attaching an X-ray protection plate in place of the detached deck. Furthermore, the X-ray protection plate may be attached to any support as long as the support can be finally used as a table as a result of attaching the X-ray protection plate.
[0032]
Further, in the above embodiment, the X-ray protection plate 1 having a specific shape is exemplified, but the design of the shape of the details can be arbitrarily changed. For example, in 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 height to a relatively high height as long as it does not hinder the medical practice of the operator. The range in which the side wall 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 not only used for interventional treatment but also for other treatment methods. It can be used in all operations, treatments and tests that use.
