Accordingly, the axes of rotation of the pair of leg receiving portions substantially coincide or substantially coincide with the axes of the patient's hip joints, and therefore, the patient's legs can be opened without exerting undue force, The legs can be closed.

[0149] According to the tenth aspect of the present invention, the clinic table includes a clinic table main body having a back plate portion, a pair of leg pedestals, a tilting means, and an opening and closing means. The second axis, which is the center of rotation of the leg receiving portions of the pair of leg receiving stands, defines a specific plane, which is substantially symmetrical with respect to an imaginary vertical plane which bisects the back plate almost bilaterally. It intersects vertically and is inclined in a direction away from the back plate toward the other end of the back plate from both left and right sides near one end of the back plate. These second axes are arranged so as to intersect on the virtual vertical plane. Each leg receiving portion is opened and closed by opening and closing means in directions approaching and separating from each other about such a second axis, so that the seated patient can be opened or closed.

According to the eleventh aspect of the present invention, a seat for supporting a patient's buttocks is provided on the back plate of the table, and the buttocks supporting surface of the buttocks is the second one. Since the buttocks are formed substantially perpendicular or almost perpendicular to the axis, the buttocks are stably received by the buttocks supporting surface that forms an obtuse angle with respect to the back plate, whereby the center of gravity of the legs is positioned on the proximal side of the leg receiving portions. In this case, the weight load of the legs on each leg support is reduced, and the legs can be smoothly opened and closed.

Further, according to the medical table of the twelfth aspect of the present invention, the pair of leg supports can be moved in the direction of closing the legs when the legs are opened, and in the direction of the legs when the legs are closed by the force of the legs of the patient. When a force is applied in a direction opposite to the rotation direction of each leg cradle, the opening / closing means stops the opening / closing operation of each leg cradle, whereby the patient's leg is forcibly opened or closed. Can be prevented. Such stopping of the opening / closing operation of each leg cradle by the opening / closing means can be realized, for example, by setting the torque of a motor for opening / closing each leg cradle to be lower than a predetermined force by the leg portions. Can be. In this way, the opening / closing operation can be stopped by the opening / closing means, so that when the patient reaches the limit position for opening the legs or the limit position for closing the legs, the respective leg cradles in the direction of opening the legs or in the direction of closing the legs automatically. Is stopped, the physical burden on the patient can be reduced, and safety can be improved.

According to the medical table according to the thirteenth aspect of the present invention, the leg receiving portions of the pair of leg receiving bases are connected by the opening and closing means so as to allow a predetermined amount of displacement. The displacement of the patient's leg with respect to the part can be tolerated, which can also reduce the physical burden of the patient at the time of opening and closing the leg.

According to the medical table of the present invention, since the opening / closing means comprises a pair of driving sources for individually driving the leg receiving portions of the pair of leg receiving tables to open and close, one of the right and left legs is provided. Even if the patient has a disability, it is not necessary to forcibly open and close the leg on the side of the disability, and the patient's left and right limit positions for opening and closing the legs, and the opening and closing speed of the left and right legs Accordingly, each of the leg supports can be individually rotated in accordance with the rotation of the pedestal, so that the burden on the patient can be reduced.

Further, according to the medical table of the present invention, when the pair of leg receivers is closed in the upright state of the back plate of the medical table main body, the first support surfaces of the leg receivers are mutually closed. Extend substantially parallel to and substantially horizontally to Therefore,
The patient sits on the main body of the examination table and places its legs on the first
It can be easily mounted on the support surface. Further, when the pair of leg receiving portions is opened in the upright state of the back plate portion of the examination table main body, the leg receiving portions expand in the left and right directions from the base side toward the distal end side. In addition, the first support surface of the leg receiving portion extends inclining upward from the base side of the leg receiving portion toward the distal end side, and extends downward inward from the left-right outer side to the inner side of the leg receiving portion. . Therefore, a wide field of view can be secured without unnecessarily opening the patient's leg at a large angle. Further, when the pair of leg supports move from the closed state to the open state, the spread angle of the leg receiving portion and the inclination angle of the first support surface toward the top side with the movement amount from the closed state, and The inclination angle inward and downward in the left-right direction is gradually increased. With this configuration, the leg can be opened without applying excessive force to the patient's leg.

According to the medical table of the present invention, the support arm provided with the leg receiving portion is pivoted about the axis extending on both sides near one end of the back plate of the medical table main body. By doing so, the leg receiving portion can be rotated between the closed state and the open state as required with a relatively simple configuration.

Further, according to the medical table of the present invention, the first support surface in the leg receiving portion of the pair of leg supports supports the patient's thigh, and by supporting in this manner, the closed position is improved. The leg of the patient can be stably supported from the state to the open state.
