In this embodiment, an electric push rod with a stroke of 100mm is preferably adopted, and the electric push rod can stay at any position, but the electric push rod can be replaced by a hydraulic push rod or a pneumatic push rod.

The fixing base 1 may be a clamping structure or a screw structure to be connected with an object to be installed, but considering that a high stability is required for a surgery, in one embodiment, as shown in fig. 4, the fixing base 1 includes a U-shaped main body 11, and a fastening wheel 6 is installed at one side of the U-shaped main body 11. The staple bolt mouth that the side pole card of U type main part 11 was gone into of being convenient for the operation table was gone into to the opening, and the side pole and the hoop end of operation table are half staple bolt form promptly and are connected to fasten through tight decide wheel 6.

As shown in fig. 5, the tightening wheel 6 in this embodiment includes a screw 61, an inner end of the screw 61 penetrates through the side wall of the fixing base 1 and then extends into the U-shaped body 11, a clamping plate 63 is installed at an inner end of the screw 61, and a rotating handle 62 is installed at an outer end of the screw 61.

The side of the U-shaped main body 11 is provided with a threaded hole 13, and a screw 61 of the fastening wheel 6 extends into the U-shaped main body 11 through the threaded hole 13. After the side rod of the operating bed is clamped into the hoop opening, the screw 61 is rotated through the rotating handle 62, so that the clamping plate 63 is continuously close to the side rod and generates locking force after being abutted against the side rod, and the relative position of the fixing seat 1 and the operating bed is kept fixed.

In one embodiment, a mounting plate 12 is formed by extending the top of one side of the U-shaped body 11, a mounting hole 15 is formed on the mounting plate 12, and the first spherical joint 2 is fixed by a screw based on the mounting hole 15. The fixing mode can provide a higher mounting surface so as to reduce the telescopic path of the telescopic rod. And further arranging the first spherical joint 2 and the setting wheel 6 to be mounted on the same side of the U-shaped body 11.

In the supporting process, the pressure of the whole elbow support is mainly applied to one side of the first spherical joint 2, the first spherical joint 2 and the tightening wheel 6 are arranged on the same side, the pressure of the tightening wheel 6 on the side rod of the operation bed can be increased, and the working stability of the whole device is ensured.

As shown in fig. 6, the spherical joint (including the first spherical joint and the second spherical joint) in this embodiment includes a cylindrical housing 21 with a hollow interior and two ends penetrating through, one end of the cylindrical housing 21 extends outward to form a mounting ring 22, a sphere 23, an elastic component 25, and an adjusting block 26 are sequentially disposed inside the cylindrical housing 21, the sphere 23 abuts against each other, one side of the sphere 23 away from the elastic component 25 protrudes out of the cylindrical housing 21 and is connected with a threaded column 24 for connecting with the telescopic rod 3, the adjusting block 26 is in threaded connection with the inner wall of the cylindrical housing 21, and the adjusting block 26 enables the spherical joint to have a free state, a damping state, and a locking state by changing the relative position with the cylindrical housing 21.
