A work table having a work surface; a pedestal unit installed on the installation surface and provided below the work table; at least one vertical movement device for moving the work table in the vertical direction; And an air suction part having an aspiration port for aspirating harmful substances emitted from an autopsy specimen, and separated from the work table part by a work table part that moves up and down via a vertical movement device The height of the work table portion is set by adjusting the vertical distance between the air suction portion and the work table portion.

The best mode for carrying out the present invention will be described with reference to the drawings. In the dissecting table / operating table 1, the work table 2 has a rectangular shape having a short side 3 and a long side 4 facing each other, and has a work surface 5 surrounded by the short side 3 and the long side 4. The short side 2 and the long side 3 are erected from the work surface 5, and the upper edge 6 of the short side 2 and the long side 3 is an installation surface 7 for the dissection table 1 (usually a floor surface, and so on). It is a horizontal plane almost parallel to. An autopsy sample or the like is placed on the work surface 5 (not shown) with the head and feet facing one short side and the other short side, respectively. Work by standing outside the short side 3 or the long side 4 of the part.

The dissecting table 1 includes a vertical movement device 8, and the work table unit 2 moves in the vertical direction via the vertical movement device 8. The vertical distance (that is, the height) between the work table part 2 and the installation surface 7 is adjusted by the work table part 2 moving in the vertical direction, and the work table part 2 is set to a predetermined height. The vertical direction refers to a direction perpendicular to an installation surface 7 (usually a horizontal plane) such as a dissecting table (hereinafter the same). In this case, the distance between the work table unit 2 and the dissection table installation surface 7 (that is, the height of the work table unit 2, the same applies hereinafter) is adjusted to be substantially constant by moving the work table unit 2 in the vertical direction. The part 2 is made to be almost horizontal. The anatomical / surgical operator sets the distance between the installation surface 7 and the work table part 2 (that is, the height of the work table part 2) according to his / her height, work posture, etc. Predetermined work can be performed. The work is normally performed in a standing state, but the work can be performed while sitting on a chair or the like by adjusting the height of the work table portion 2.

Further, the distance between the work table portion 2 and the installation surface 7 is adjusted to be different at least at two arbitrary positions so that the work table portion 2 is inclined. The inclination of the work table portion 2 is usually an inclination due to a difference in height between the opposing short side portions 3 and 3. That is, one short side portion 3 (left side in FIGS. 1 to 3, hereinafter referred to as the front side) is lowered, and the other short side portion 3 (right side in FIGS. 1 to 3, hereinafter referred to as the rear side) is increased. An autopsy specimen is placed on the work surface 5 of the work table portion 2 inclined downward in the front-rear direction with the head directed to the lower front short side 3 side and the foot directed to the lower rear short side 3 side. Is done. Even in the same specimen, there is a difference in height (interval between the work surface 5 and a predetermined part) depending on the part, which makes it easy to work on a part at a relatively high position such as the head and chest. become.

Thus, the tilting state of the workbench part 2 can be adjusted according to the target site of the work.
At the same time, the height of the work table portion 2 can be set as appropriate. The degree of inclination of the work table 2 is arbitrary. The inclination by the height difference between the long side parts 4 and 4 which oppose is also possible, and the combination of these inclination may be sufficient. Note that the work surface 5 of the work table portion has a partial inclination, unevenness, etc. (not shown), but the determination of the horizontal state / inclination state of the work table portion 2 is performed using a certain reference surface of the work table portion, For example, the determination may be made with reference to the short edge portion 3 or the upper edge surface 6 of the long edge portion 4 erected from the work surface.

The dissecting table / operating table 1 may have a structure including an air suction part 11 having a suction port 10 (see FIGS. 7 to 10). It should be noted that the basic structure is the same as that of the dissection table and the like, and the same reference numerals are used to describe the structure. From an autopsy specimen placed on the work surface 5, harmful substances such as formaldehyde, fine sections, etc. (hereinafter referred to as “toxic substances”) are emitted. In this case, air containing harmful substances is contained in the air suction unit 11. It is sucked from the suction port 10. That is, the air suction part 11 has a horizontally long box shape and is hollow inside, and a horizontally long suction port 10 is formed on the inner side surface 12 of the air suction part 11. The air suction part 11 is arranged around the work table part 2. As a specific example of the air suction portion 11, there is a plenum box (see JP 2009-226222). However, any structure that sucks harmful substances may be used, and the shape and size of the air suction portion 11 and the suction port 10 are not limited. Further, arranging in the peripheral part means arranging in the whole or a part of the peripheral part. In FIG. 7, the pair of air suction portions 11 are disposed to face each other along the long side portion 4, but may be disposed along the four circumferences or the short side portion of the work table portion (not shown).

In the structure including the air suction part 11, there are two types of arrangement relations between the work table part 2 and the air suction part 11. That is, one is that the work table part 2 and the air suction part 11 are integrated, and the other is that the work table part 2 and the air suction part 11 are not integrated, and the air suction part 11 and the work table part 2 are separated. Yes. First, in the structure in which the work table part 2 and the air suction part 11 are integrated, the height of the work table part 2 is adjusted via the vertical movement device 8 as described above. The air suction part 11 integrated with the part 2 also moves in the vertical direction. Also here, the integrated work table part 2 and the air suction part 11 are in a horizontal state, and the integrated work table part 2 and the air suction part 11 are in an inclined state. In any case, after the height of the work table portion 2 is set, the arrangement relationship between the work table portion 2 and the air suction portion 11 does not change, and the suction function to be performed by the air suction portion 11 is maintained as it is. 10 and 11 illustrate a state in which the integrated work table portion 2 and the air suction portion 11 are moved (in this case, inclined movement) via the vertical movement device 8. In addition, integration with the worktable part 2 and the air suction part 11 uses well-known fixation and fixing means, such as adhesion | attachment and a screw | thread. The air (hazardous substance) sucked at the suction port 10 is further guided to the air collecting chamber 39 via the suction duct 37, and the duct 37 has a flexible structure so that it can cope with the vertical movement of the air suction portion 11, for example, Make it bellows.

Next, in the structure in which the air suction part 11 and the workbench part 2 are separated, the height of the workbench part 2 is adjusted via the vertical movement device 8, but the air suction part 11 and the workbench part 2 are Only the work table part 2 moves up and down without moving up and down integrally. As shown in FIG. 8, a bracket 36 is attached to the upper end portion of the vertical frame 31 of the pedestal portion. That is, the lower end of the bracket 36 is inserted into the upper end of the vertical frame 31 and is fixed to the vertical frame 31 with a fastening screw 33. The horizontal support portion 40 supports the air suction portion 11 from below, and the air suction portion 11 is It is stationary.
With respect to the air suction part 11 in such a stationary state, the work table part 2 moves alone in the vertical direction. In FIG. 7, the long side portion 4 is in contact with the inner side surface 12 of the air suction portion 11 disposed outside the long side portions 4, 4, and the work table portion 2 moves vertically along the inner side surface 12 of the air suction portion 11. Moving.
Thus, the vertical distance between the air suction part 11 and the work table part 2 separated from the work table part 2 by the work table part 2 that moves in the vertical direction via the vertical movement device 8, specifically the air The distance between the suction port 10 of the suction part 11 and the work table part 2 in the vertical direction is adjusted, and the height of the work table part 2 is set.

Also here, there are a work table part 2 in a horizontal state with respect to the stationary air suction part 11 and a work table part 2 in an inclined state with respect to the stationary air suction part 11, depending on the purpose and situation. Can be selected. FIG. 9 conceptually shows a state in which the work table part 2 is inclined downward from the rear (right side in FIG. 9) to the front (left side in FIG. 9) with respect to the stationary (fixed) air suction part 11. FIG. The autopsy specimen placed on the work surface 5 is different in the height of the chest, abdomen, and foot on the work surface 5 (interval between the work surface 5 and the upper surface of the predetermined portion of the autopsy specimen). In some cases, the height of the chest and abdomen is an obstacle, and harmful substances emitted from the subject are not sufficiently sucked from the suction port 10. In this case, the vertical distance between the suction port 10 of the air suction portion 11 and the work table portion 2 (specifically, the work surface 5) is adjusted according to the height of the subject to be examined from the work surface 5. Therefore, the work table portion 2 is inclined so that the work surface on the head side of the work table portion 2 is lowered, and the suction port 10 of the air suction portion 11 and the work table portion 2 (work surface 5) Adjust the interval. Thereby, the harmful substance is reliably sucked from the suction port 10 without being greatly affected by the height of each part. By tilting the work table part 2 such as by lowering the work surface on the head side, the distance (distance) between the autopsy specimen and the worker's breathing zone becomes longer, and the risk that the worker will be exposed to harmful substances There is also an advantage that can be reduced. Further, the work table part 2 is moved in the vertical direction with respect to the stationary air suction part 11, and the vertical distance between the suction port 10 of the suction part 11 and the work table part 2 is adjusted, so that the harmful substance is sucked into the suction port. 10 is efficiently sucked in and the diffusion of harmful substances is prevented. The vertical direction means a direction perpendicular to the installation surface 7 (usually a horizontal plane) such as a dissecting table.

Further, the work table portion 2 is moved in the vertical direction with respect to the stationary air suction portion 11 so that the upper end surface 6 of the long side portion and the upper surface portion 41 of the air suction portion (plenum box) 11 are substantially the same height. Can do. This facilitates the work of transferring the specimen to be examined from the long side portion 4 side to the work surface 5 of the worktable portion and placing it thereon. On the contrary, it is easy to move the subject to be examined placed on the work surface 5 from the work table 2 and to lower it. Since it is easy to perform such related work, the work load on the anatomical / surgical operator is reduced. It goes without saying that the work table part 2 can be returned to a predetermined height by the vertical movement of the work table part 2 after the movement of the specimen. The upper surface 41 of the air suction part (plenum box) 11 is a horizontal plane substantially parallel to the installation surface 7 of the dissection table 1 or the like.

The surgery / dissection table 1 includes a swing prevention device 27 for the work table 2. The swing prevention device 27 prevents the work table unit 2 supported by the vertical movement device 8 from swinging. The swing prevention device 27 is a combination of a guide 28 provided on the vertical frame 31 of the pedestal portion and a guide rod 29 provided on the work table portion 2. The guide rod 29 is inserted into the elongated guide hole 28, and the guide The guide rod 29 can be moved in the hole 28. In other words, the guide rod 29 moves in the guide hole 28 in accordance with the inclination of the work table portion 2, while contacting with the inner peripheral surface of the elongated guide hole 28, the movement range thereof is restricted, and unnecessary swing of the work table portion 2 is performed. Is prevented. When the guide rod 29 comes into contact with either one of both ends of the elongated guide hole 28, the tilting motion of the work table portion 2 is stopped.
The structure, arrangement location, and number of the swing preventing device 27 are arbitrary. In the surgery without the air suction part 11, the dissection table 1 (FIGS. 1 and 2) has three swing prevention devices 27, and in the surgery with the air suction part 11, the dissection table 1 (FIG. 7) The number of anti-swing devices 27 is two.

The work table portion 2 is disposed above the pedestal portion 9, and the work table portion 2 moves in the vertical direction via a vertical movement device 8 interposed between the work table portion 2 and the pedestal portion 9. The pedestal portion 9 is installed on an installation surface (usually a floor surface) 7. The pedestal portion 9 has a moving leg ring 32 at the lower end, but the leg ring 32 may not be provided (not shown). The vertical movement device 8 is not limited to the structure arranged below the work table unit 2. In the illustrated case, the vertical movement device 8 is a mechanical jack device, but may be an electric, hydraulic, pneumatic jack device or other vertical movement device. Two jack devices 8 are arranged on the front short side 3 side and one on the rear short side 3 side. The number of the vertical movement devices 8 can be arranged arbitrarily, but a plurality of vertical movement devices 8 are usually provided in the inclined work table portion. As described above, in the work table unit 2 in the horizontal state, the distance between the work table unit 2 and the setting surface 7 of the dissection table 1 (that is, the height of the work table unit 2) is substantially constant. Further, in the work table part 2 in the inclined state, the distance (height) between the work table part 2 and the installation surface 7 is different in at least two arbitrary locations. These heights are adjusted by vertical movement by the jack device 8.

The illustrated jack device 8 is a pantograph jack, and includes an upper link mechanism having an upper arm 17 and a lower link mechanism having a lower arm 18. By rotating the screw rod 16, the upper and lower link mechanisms perform an upright operation or a lowering operation, and the upper spherical support portion 15 moves up and down with respect to the base portion 19. The base portion 19 of the pantograph jack is fixed to a horizontal member 21 provided on the pedestal portion 9, and the support shaft 13 is fixed to the upper portion of the pantograph jack 8 by a fixing portion 20. A spherical support portion 15 at the upper end is provided at the tip of the support shaft 13, and the spherical support portion 15 at the upper end is pivoted (pivoted) to the concave receiving portion 34 of the receiving member 22 on the back surface of the work table 3. The receiving portion 34 is pivotally supported by the spherical support portion 15 so that it can follow the inclination of the work table portion 2.

The operation of rotating the screw rod 16 is performed via a gear rotation mechanism. First, the shaft 14 is rotated by the handle 14, and the shaft angle changing device 35 (worm gear wheel, bevel gear, etc.) converts the rotation of the shaft 23 into the rotation of another shaft 24, and further changes the height of the jack (up and down movement). The screw rod 16 is rotated through a universal joint 25 which can be adapted. In this case, the cover portion 26 of the gear rotation mechanism corresponds to the horizontal movement of the screw rod 16 and slides on the rail portion 38 provided on the pedestal portion 9 (upper frame) in the horizontal direction.

The surgical and dissecting table 1 includes a filter device 30 for harmful substances. Air containing harmful substances emitted from the autopsy specimen is sucked from the suction port 10 of the air suction part 11 by driving a blower (not shown) arranged on the downstream side, and the air suction part 11 (plenum box). To the duct 35, the air collecting chamber 37 disposed on the pedestal 9, and further to the filter device 30, and after removing harmful substances by the filter device 30, it is exhausted to the outside.

In this way, the vertical movement of the workbench unit sets the height including the inclination of the workbench unit according to the height and working posture of the anatomical / surgical operator, the processing site, the purpose and situation of the work, etc. -The workload of the surgical operator is reduced. In addition, the risk of anatomical / surgical workers being exposed to harmful substances, such as formaldehyde, emanating from autopsy specimens during dissection and surgery is prevented and reduced, and health management problems are overcome. Hazardous substances emitted from autopsy specimens are inhaled because the respiratory area of the anatomical / surgical operator overlaps with the diffusion area of harmful substances, but due to the vertical movement (including tilting movement) of the work table It is possible to effectively prevent the risk of exposure to harmful substances by adjusting the distance between the two areas so that the respiratory area and the diffusion area of harmful substances do not overlap.
