So that the patient's head, torso, thigh, and legs can be in a preferred posture. Are provided so that the tilt angle and the like can be adjusted. Further, an attachment 22 as shown in FIG. 4 on which the patient's arm can be placed is detachably attached to the operating table main body 21. Specifically, the operating table main body 21 includes The rail member 20 for attaching the attachment 22 to both sides is provided. In addition, the attachment 22 includes a clamp member 23 that clamps a desired portion of the rail member 20 of the operating table main body 21 and a placement member 24 that places a part of the patient's body via a pivot shaft 25. And are configured to be rotatable. And the regulating member 26 for fixing the rotation angle of the clamp member 23 and the mounting member 24 at a desired angle is slidably attached to the mounting member 24 of the attachment 22. As a result, the attachment 22 is fixed at a predetermined angle by rotating the mounting member 24 with respect to the operating table main body 21, so that a part of the patient's body is placed on the mounting member 24 positioned at a desired position. Can be placed.

  Each of the members 21a, 21b,... On which the patient's head, torso, thighs, and legs of the operating table main body 21 are mounted is adjusted by adjusting an inclination angle of each member. However, due to the presence of the adjusting lever 27, a certain restriction may occur in the attachment location of the attachment 22.

  The present invention has been made to solve the above-described conventional drawbacks, and an object of the present invention is to place a placement member for placing a part of a patient's body at a desired position at a desired position. It is to provide an operating table and an operating table attachment that can be used.

  Accordingly, the operating table according to claim 1 is an operating table including an operating table main body on which a patient is placed during an operation, and an attachment 1 having an attachment member 2 attached to the operating table main body. Includes a mounting member 9 on which a part of the patient's body is mounted, and a link member 5 for connecting the mounting member 9 and the mounting member 2, and the link member 5 is rotatably connected to the mounting member 2 via the first pivot shaft 4 and is pivotally connected to the mounting member 9 via the second pivot shaft 8. Moreover, the rotation angle between the link member 5 and the mounting member 2 and the rotation angle between the link member 5 and the mounting member 9 are provided so as to be fixed at a desired angle. To do.

  In the operating table according to claim 1, by setting the two rotation angles of the mounting member 9 and the link member 5 and the rotation angle of the link member 5 and the attachment member 2 as desired, The mounting member 9 can be positioned at a desired position.

  Further, the operating table according to claim 2 restricts rotation and fixation between the link member 5 and the mounting member 2 and restricts rotation and fixation between the link member 5 and the mounting member 9. The regulating member 11 is provided with a rotating state between the link member 5 and the mounting member 9 when the link member 5 and the mounting member 2 are turned. When the member 5 and the mounting member 2 are fixed, the link member 5 and the mounting member 9 are provided so as to obtain a fixed state.

  In the operating table according to claim 2, two rotation angles, that is, a rotation angle between the mounting member 9 and the link member 5 and a rotation angle between the link member 5 and the attachment member 2, by operation of one restriction means. Can be set and changed as desired.

  Further, the operating table according to claim 3, wherein the restriction member 11 is provided on the link member 5 or the attachment member 2 so as to restrict the rotation and fixation between the link member 5 and the attachment member 2. A first engagement / disengagement member 12 that can be engaged / disengaged with the engaging portion 3, a first member provided on the link member 5 or the placement member 9 to restrict the rotation and fixation of the link member 5 and the placement member 9. A second engagement / disengagement member 13 that can be engaged / disengaged with the two locking portions 6, an operation portion 14 that is provided integrally with the second engagement / disengagement member 13 and that can be held and operated by an operator, A connecting member 16 that connects the one engagement / disengagement member 12 and at least a portion located near the second pivot shaft 8 is flexible, and the first engagement / disengagement member 12 and the first locking portion 3 Characterized in that it is provided with an elastic member 17 that is always elastically biased in the direction in which the locked state is obtained. To.

  In the operating table according to the third aspect, the second engagement / disengagement member 13 is detached from the second locking portion 6 by the operation of the operation portion 14 to freely rotate the link member 5 and the mounting member 9. At the same time, the first engagement / disengagement member 12 connected via the connection member 16 is also detached from the first locking portion 3, so that the link member 5 and the attachment member 2 can be freely rotated. On the other hand, after the mounting member 9 is moved to a desired position in this free state, when the operation of the operation portion 14 is released, the first engagement / disengagement member 12 and the first locking portion 3 are released by the elastic member 17. , The rotation of the link member 5 and the mounting member 2 is restricted, and the second engagement / disengagement member 13 is connected to the first engagement / disengagement member 12 via the connection member 16. Therefore, the locked state of the second engaging / disengaging member 13 and the second locking portion 6 is obtained, and the rotation of the link member 5 and the mounting member 9 is restricted. In this way, the two rotation angles can be set and changed as desired by operating one operation unit 14. Even if the linear distance between the operation unit 14 and the first engagement / disengagement member 12 is changed by changing the rotation angle between the mounting member 9 and the link member 5, the connecting member 16 is at least the first member. Since the part located in the vicinity of the two pivot shafts 8 is flexible, the distance connecting the operation unit 14 and the first engaging / disengaging member 12 is substantially constant.
