Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-3. The utility model provides a technical solution: a surgical extracorporeal support device, including a mounting seat 1, a side of the mounting seat 1 is provided with an open groove, the mounting seat 1 is clamped on the side of the surgical platform 10 through the open groove, and the upper surface of the mounting seat 1 is threadedly installed with a first locking knob 11, and the mounting seat 1 is fixed on the surgical platform 10 by pressing the first locking knob 11.

A guide sleeve 2 is fixedly installed on the side of the mounting seat 1, a gear box 3 is fixedly installed on the bottom end of the guide sleeve 2, a telescopic rod 4 is slidably inserted in the guide sleeve 2, a cantilever bracket is fixedly installed on the top of the telescopic rod 4, the cantilever bracket includes a mounting beam 12 and a cantilever arm 13, the mounting beam 12 is fixedly installed on the top of the telescopic rod 4, two sliding rods 14 are fixedly installed inside the mounting beam 12, a sliding seat 15 is slidably installed on the surface of the two sliding rods 14, and the cantilever arm 13 is fixedly installed on the sliding seat 15.

A threaded hole is provided on the side of the sliding seat 15, and a second locking knob 16 is threadedly inserted into the threaded hole. A sliding slot 17 running through the left and right sides is provided on the side of the mounting crossbeam 12, and the straight rod section of the second locking knob 16 passes through the sliding slot 17. Two independent sliding seats 15 are slidably provided on the surface of the sliding rod 14. Both sliding seats 15 are fixedly installed with cantilever arms 13, and the two cantilever arms 13 are arranged in parallel. The spacing between the two cantilever arms 13 is adjustable so that the patient's limbs can be suspended by hanging straps.

The bottom end of the telescopic rod 4 passes through the gear box 3. A manual adjustment component is arranged in the gear box 3, and the telescopic rod 4 is driven to slide up and down by the manual adjustment component.

Specifically, the manual adjustment component includes a gear plate 5, a worm wheel 6, a worm 7 and a crank 8. The first rotating shaft 20 and the second rotating shaft 21 are rotatably installed in the gear box 3 respectively. The gear plate 5 and the worm wheel 6 are fixedly installed on the first rotating shaft 20. The worm 7 is fixedly connected with the second rotating shaft 21 coaxially. The end of the second rotating shaft 21 extends to the outside of the gear box 3 and is fixedly connected to the crank 8. The worm wheel 6 and the worm 7 are meshed for transmission. A plurality of tooth grooves 9 are opened on the surface of the telescopic rod 4. The gear plate 5 is meshed with the tooth grooves 9 on the surface of the telescopic rod 4 for transmission.

A support plate 18 is clamped on the surface of the cantilever arm 13, a support pad is fixedly provided on the upper surface of the support plate 18, and a plurality of clamps 19 are fixedly installed on the lower surface of the support plate 18. The plurality of clamps 19 are respectively tightly connected to the surfaces of the two cantilever arms 13. By installing the support plate 18 on the cantilever arm 13, support and lifting from bottom to top can be achieved. It should be noted that the support plate 18 and the mounting beam 12 can produce relative sliding. During surgery, the limb is placed on the support plate 18. When the height of the support plate 18 is adjusted, relative friction displacement between the limb and the support plate 18 can be avoided, which may cause pulling of the wound.

After the support plate 18 is disassembled, the cantilever arm 13 can be used for suspension support to meet the different usage requirements of different surgical positions, which is more practical.

As shown in FIG. 1 , the device is installed on the side of the surgical platform 10 and is fixedly connected to the surgical platform 10 via the mounting base 1 , so that stability is guaranteed, and multiple supporting devices can be selected for use at the same time without affecting each other.

The supporting device controls the lifting and lowering of the telescopic rod 4 by shaking the crank 8 to achieve height adjustment of the cantilever bracket. When the crank 8 is shaken, power is transmitted through the worm wheel 6 and the worm 7. Since the worm wheel 6 can only be driven to rotate by the worm 7, the worm 7 cannot be driven to rotate in the reverse direction by the worm wheel 6. Therefore, it has a self-locking effect, so that the telescopic rod 4 can remain stopped at any telescopic length. The adjustment is convenient and labor-saving, and the requirement of being able to adjust to different heights while bearing the weight of the limbs during surgery is met.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
