  The arm unit 30 includes an arm 32 and a support 35 that rotatably supports the arm 32. The arm 32 has a base body that is formed in a band shape with a tip portion bent downward, and an annular mounting portion 34 that is attached to the pivot 11 for pivotally supporting the arm 32 is provided at a rear portion of the base body. Yes.

  The support 35 includes a housing 36 having a space that can accommodate the rear including the attachment portion 34 of the arm 32, and flange portions 36 a that protrude outward are provided on both sides of the housing 36. The flange portion 36a is formed with a plurality of through holes (not shown) arranged coaxially with a hole portion formed in the front end surface of the main body 20 (not shown), and the screw 37 is screwed into the hole portion through the through holes. Thereby, the main body 20 and the arm part 30 are fixed.

  As shown in FIGS. 3 and 4, the space of the housing 36 communicates with a first space 38 extending rearward from an opening 36 b formed at the front end portion of the housing 36 and the rear of the first space 38. And a second space 39 extending in the vertical direction.

  A pivot 11 extending horizontally in the left-right direction is provided in the first space 38, and an attachment portion 34 is rotatably attached to the pivot 11 so that the arm 32 is rotatably supported.

  Further, an expandable and contractible annular spring member 41 having a through-hole portion 41a is disposed in the second space 39 and below the rear portion of the arm 32, so that the spring against the upward movement of the front portion of the arm 32 is provided. A biasing force due to the elastic force of the member 41 is generated.

  Therefore, the connector 5 placed on the extension table 110 is fixed by the urging force generated in the arm 32 between the extension table 110 and the arm 32. Also, the tip of the arm is bent downward, and this bent portion holds the outside of the connector 5 and prevents the connector 5 from coming out outward.

  In the second space 39, an adjustment mechanism 60 (adjustment means of the present application) that adjusts the urging force generated in the arm 32 is provided. The adjustment mechanism portion 60 is disposed in contact with the lower end of the spring member 41, and has a flat plate-like support member 62 that supports the spring member 41 with the rear portion of the arm 32, and a through-hole that is provided at the center of the spring member 41. And a rotating body 65 having a shaft 65a that is inserted into a through hole 32a formed in the rear part of the arm 32 formed coaxially with the portion 41a and the through hole 41a.

  The rotating body 65 includes a manual operation head 65b disposed outside the upper portion of the housing 36, and a shaft 65a extending from the head 65b through the upper surface of the housing 36 in the vertical direction. The shaft 65a is rotated by rotating the head 65b.

  Then, by the manual rotation operation of the head 65b of the rotating body 65, the head 65b rotates at that position without moving up and down, and only the support member 62 screwed with the shaft 65a is indicated by an arrow in FIG. To move up and down. The biasing force of the arm 32 is adjusted by expanding and contracting the spring member 41 by the vertical movement of the support member 62.

  In addition, although the urging | biasing force of the arm 32 is raised by contracting the spring member 41, the movable range of the arm 32 becomes narrow. On the other hand, by releasing (extending) the spring member 41, the urging force of the arm 32 is reduced, but the movable range of the arm 32 is widened.

  Next, the attachment / detachment mechanism 45 for attaching / detaching the main body 20 to / from the extension table 110 will be described with reference to FIGS. 4 and 5. It is assumed that the extension table 110 of this embodiment is made of a ferromagnetic material (a magnet is attracted).

  The attaching / detaching mechanism 45 controls the extension table 110 to the main body 20 by controlling on / off (the presence or absence of magnetization between the magnetic members 71, 71) of the magnetic member 71 (magnetic body of the present application) provided in the main body 20. Is to be attached and detached.

  The attachment / detachment mechanism portion 45 is provided in the main body 20, and the main body 20 includes, as shown in FIG. 4 (b), flat plate-like magnetic members 71 and 71 having different magnetic poles arranged at the front and rear, and FIG. ), Nonmagnetic members 72a and 72b formed of synthetic resin or the like disposed between magnetic members 71 and 71 having different magnetic poles, and the magnetic poles are divided on the front and rear sides to have different magnetic poles. Magnetic members 71 and 71 are arranged. The outer shape of the main body 20 is formed by the shape of the magnetic member 71 and the nonmagnetic members 72a and 72b, and is formed in a substantially rectangular parallelepiped shape.

  As shown in FIGS. 4 and 5, the nonmagnetic members 72 a and 72 b are arranged so as to sandwich the upper and lower sides of a permanent magnet 73 arranged with the N and S poles facing each other at the center. A permanent magnet 73 is attached adjacently to a yoke 74 (yoke) having the same polarity to enhance the magnetic force.

  The nonmagnetic member 72a provided in the upper part is exposed to the outside of the upper end portion of the main body 20 via a connecting member 76 formed of a nonmagnetic material that is rotatably connected to the magnetic members 71, 71. And is rotated together with the permanent magnet 73 including the yoke 74 by manual rotation of the operating body 75 as shown in FIG.

  As shown in FIG. 5, the permanent magnet 73 is rotated by the rotation operation of the operating body 75, the magnetic pole direction of the permanent magnet 73 with respect to the magnetic member 71 is switched, and the magnetic member 71 divided on both sides by the nonmagnetic member 72, By switching the action direction of the magnetic lines of force G between 71, it is possible to switch between the magnetic members 71 and 71 so as not to magnetize.

  As shown in FIG. 4B and FIG. 5B, when the magnetic members 71 are magnetized, the magnetic lines of force G are formed outside the main body 20, so that the main body 20 is the extension table. 4A and 5A, when the magnetic members 71 are not magnetized, magnetic lines of force G are formed inside the main body 20. Therefore, the main body 20 is not attracted to the extension table 110, and the main body 20 can be freely moved with respect to the extension table 110.

  The number of the magnetic members 71 and 71 is appropriately set according to the mode of the adsorption capacity.

  Further, a non-magnetic cover member 78 is attached to the lower end of the main body 20, the inside is sealed with the connecting member 76, and the permanent magnet 73 disposed between the magnetic members 71, 71 on both sides. The nonmagnetic member 72 is held.

  Then, when the user rotates the operation body 75 exposed on the upper portion of the main body 20, the permanent magnet 73 is rotated to switch the magnetic pole direction with respect to the magnetic members 71 and 71. As a result, the attraction force by the magnetic members 71 and 71 having different magnetic poles divided on both sides of the main body 20 is controlled to be turned on / off, and the main body 20 is attracted and fixed to the extension table 110 by the on-control of the attraction force. Then, the adsorption to the extension table 110 is lost by the off-control of the adsorption force, and the fixing device 10 can be freely moved on the extension table 110.

  As described above, the fixing device 10 according to the present embodiment can turn on and off the attractive force between the magnetic members 71 and 71 only by rotating the operation body 75, so that the main body 20 is easily positioned and fixed to the extension table 110. Or move.

  In addition, the fixing device 10 is convenient because it can be attached and detached with one action (only rotation operation) when it is necessary to remove it from the extension table 110. In addition, since the medical device 5 and the fixing device 10 can be attached / detached with a simple operation, the time required for the attachment / detachment can be easily shortened and the work efficiency can be increased.

(Configuration of table and extension table)
Next, the structure of a table and an extension table is demonstrated using FIG.
The table 100 is placed on the bed 1 and has a size enough to cover at least the lower body including the abdomen of the patient lying on the bed 1.

  A plurality of legs 102 are attached to the table 100 including four corners below. The leg body 102 includes a shaft that can be raised and lowered, and the length thereof can be freely adjusted according to the patient's body shape and the like.

  Further, the table 100 is configured by connecting a pair of front and rear table portions 101, 101 via a hinge (not shown), is foldable, and can be accommodated in a small size.

  In addition, on both sides of the front end portion of the table 100, extension tables 110 that can extend the length of the table 100 in the length (vertical) direction are detachably provided.

  Further, the partial region of the front portion of the table 100 and the extension table 110 are formed of a member made of a ferromagnetic material (a magnet is attracted). Note that only the region or surface to which the fixing device 10 is attached may be made of a ferromagnetic material.

  The extension table includes a flat base having a region where a medical device can be placed. Although not shown, the extension table 110 is connected to a guide rail provided on the lower end surface of the table 100 extending in the width (left and right) direction via a connecting member. Therefore, the extension table 110 can be freely moved manually in the width direction of the table 100 as shown by the arrow in FIG.

  Further, the extension table 110 is attached to the patient head side end of the table 100 via a connecting member having a ball joint (the bending means of the present application), and as shown by an arrow in FIG. Although it is rotatable in the vertical direction, it can be stored below the table 100 by rotating in the horizontal direction, or can be projected to the front portion of the table 100 as shown in FIG.

  Further, the extension table 110 can be tilted (bent) as shown in FIG. 1 by rotating in the vertical direction, and the fixing position of the connector 5 can be appropriately adjusted between the table 100 and the patient.

  Furthermore, the extension table 110 is composed of two plate-like members arranged above and below, and the length of the extension table can be expanded and contracted by relatively moving the two members.

  Thus, since the extension table 110 can be positioned in the left-right direction and tilted in front of the table 100, the extension table 110 can be appropriately positioned at an optimum position. Further, when the extension table 110 is not required, it can be stored below the table 100. Furthermore, by extending or contracting the length of the extension table 110, the extension table 110 can be brought closer to the patient side or separated from the patient.
