As described above, since the connecting portion 41 of the clamp mechanism 30 is provided with the protruding portion 40 that protrudes from the connecting body portion 42 and is slidably fitted in the inner space of the guide portion 12 along the guide portion 12 , The protruding portion 40 has: the external dimension in the first direction perpendicular to the protruding direction and the external dimension in the second direction perpendicular to the protruding direction and intersecting with the first direction, which are connected to the connecting body portion 42 and are respectively compared with each other. The neck portion 43 having a smaller opening width on the surface side of the guide portion 12 and the neck portion 43 connected to the tip of the protruding portion 40 and having external dimensions in the first and second directions are respectively larger than the openings on the surface side of the guide portion 12 . Since the width of the head portion 44 is larger and smaller than the width of the rear side of the guide portion 12 , the angle of the protruding portion 40 can be changed in plural directions with respect to the guide portion 12 .

The table mounting mechanism 10 includes a groove-shaped guide portion 12 formed in the mounting table 11 with a width on the rear side larger than the opening width on the front side, and a groove-shaped guide portion 12 that is connected to the guide portion 12 and extends from the guide portion 12 . Since the connecting portion 41 can be inserted into and removed from the opening 17, the connecting portion 41 can be inserted and removed from the guide portion 12, and the angle posture of the clamp mechanism 30 including the connecting portion 41 can be changed according to the angle of the lever.

Since the connecting portion 41 is provided with the locking portions 45a, 45b, 45c for locking the clamp mechanism 30 guided toward the guide portion 12 to the locking portion 21, the locking portions 45a, 45b, 45c are When the clamp mechanism 30 is guided toward the guide portion 12 in a direction perpendicular to both the protruding direction of the protruding portion 40 and the first direction, the clamp mechanism 30 is locked to the first locked portion 45 a of the locking portion 21 . , 45c, and the clamp mechanism 30 are constituted by a second latched portion 45b that is latched on the latching portion 21 when guided toward the guide portion 12 in a direction perpendicular to both the protruding direction and the second direction. Therefore, when the protruding portion 40 of the clamp mechanism 30 is fitted by changing the angle, the first locked portions 45 a and 45 c or the second locked portion 45 b can be locked to the locking portion 21 .

Assuming that a large load is applied to the fixing device 1, even if the protruding portion 40 of the clamp mechanism 30 receives an external force in the direction of falling off the guide portion 12 of the table setting mechanism 10 and the protruding portion 40 is inclined with respect to the guide portion 12, the main body portion is connected to the protruding portion 40. The sliding surface 47 of 42 is in contact with the surface 15 of the guide portion 12 along the table 11 , so that the peripheral portion of the opening of the guide portion 12 can be suppressed so that the protruding portion 40 does not come off from the guide portion 12 . As a result, even if a large load is applied to the fixing device 1, the medical device 2 can be strongly fixed in a state where the locking portion 21 is locked to the locked portions 45a, 45b, and 45c.

By pressing the button 23, the locking pawl 22 is retracted to the unlocked position of the locked portions 45a, 45b, and 45c. Since the locked portions 45 a , 45 b , and 45 c do not pass over the locking pawls 22 when the projecting portion 40 is moved along the guide portion when the locking is released, it is not necessary to lift the projecting portion 40 from the guide portion 12 .

Therefore, the protruding length of the neck portion 43 of the protruding portion 40 can be made equal to the thickness of the sliding portion of the guide portion 12 , so that the protruding portion 40 can be prevented from swimming with respect to the guide portion 12 . As a result, even if a large load is applied to the fixing device 1 and the protruding portion 40 is inclined with respect to the guide portion 12, the opening end edge of the guide portion 12 can be prevented from being deformed in a direction away from each other.

Furthermore, since the locking portion 21 is provided with the locking claw 22 provided on the locking portion 21 to position the clamp mechanism 30 or the table setting mechanism 10 at a predetermined position, a button is integrally formed above the locking claw 22 23. The button 23 and the locking claw 22 are urged in the locking direction by the elastic member 24, so the locking claw 22 can be locked on the locked portions 45a and 45b by the pushing force of the elastic member 24. , 45c state.

Furthermore, when connecting the clamp mechanism 30 and the table setting mechanism 10, the protruding portion 40 can be easily slid toward the guide portion 12 so that the locked portions 45a, 45b, and 45c ride on the inclined surface 27 of the locking claw 22. The locking claws 22 are locked to the locked portions 45a, 45b, and 45c.

Furthermore, the arm portion 33 of the clamp body portion 32 overlapping the connection body portion 42 and the bolt 36 provided on the extension portion 34 of the clamp body portion 32 hold the rod 3 in, and only the bolt 36 is tightened. The rod 3 can be clamped. As a result, the clamp mechanism 30 of the fixing device 1 can be easily fixed to the rod 3 .

Furthermore, the to-be-locked portions 45 a , 45 b , and 45 c can be locked to the locking portion 21 in a state where the gripping mechanism 30 is selectively gripping the lever 3 in plural directions.

When the clamp mechanism 30 is connected to the table setting mechanism 10, since the regular square column-shaped neck portion 43 is fitted in the guide portion 12, the clamp mechanism 30 becomes difficult to rotate. Therefore, the clamp mechanism 30 can only be moved by directly moving the clamp mechanism 30. The stop portion 21 is locked to the locked portions 45a, 45b, and 45c. Furthermore, since at least three to-be-locked parts 45a, 45b, and 45c are formed, the clamp mechanism 30 can be locked to the table setting mechanism 10 in at least three directions.

The part along the guide portion 12 of the table 11 is inserted between the sliding surface 47 near the neck 43 and the head 44, so as to eliminate the play along the sliding surface 47 and the surface 15 of the guide portion 12 of the table 11 Therefore, even if a large load is applied to the fixing device 1, the protruding portion 40 is inclined with respect to the guide portion 12, and the opening edge of the guide portion 12 can be prevented from being deformed in a direction away from each other.

Since the locked portions 45, 45a, 45b, 45c are fitted between the surface of the button 23 on the locking claw 22 side and the locking claw 22, the locked portions 45, 45a, 45b, 45c do not need to be in the button 23 and the locking pawl 22.
