[0032] In some embodiments, the working principle of the orthopedic retractor lifting device is as follows: when the foot switch is pressed on the ascending side, the electric push rod 3 contracts, driving the outer column 8, the orthopedic retractor support frame 11, and the orthopedic retractor interface 12 to move upward, and the femoral head is lifted upward through the retractor device to expose the femoral head to the surgical field of view; when the foot switch is released, the electric push rod 3 stops moving, and the orthopedic retractor support frame 11 supports the retractor device to keep the femoral head in a stable surgical position; when the foot switch is pressed on the descending side, the electric push rod 3 extends, driving the outer column 8, the orthopedic retractor support frame 11, the orthopedic retractor interface 12 and the retractor device to move downward, and the femoral head moves to its original position under the action of its gravity and ligament tension.

[0033] In some embodiments, the structural diagram of the column frame of the orthopedic retractor lifting device of the utility model embodiment is as follows Figure 2 shown. Figure 2 This is a schematic diagram of the structure of the column frame of an orthopedic retractor lifting device. The upper end of the column frame 4 is provided with a fourth threaded hole 20.

Screws passing through the first threaded holes 13 secure the friction plate 6 to the outer column 8, while also pressing the friction plate 6 against the wall of the lower end of the column frame 4, effectively closing the gap between the column frame 4 and the outer column 8.

[0035] In some embodiments, the structural diagram of the outer column of the orthopedic retractor lifting device of the utility model embodiment is as follows Figure 4 shown. Figure 4This is a schematic diagram of the structure of an outer column for an orthopedic retractor lifting device. Two second through holes 16 are provided at one end of the outer side surface of the outer column 8 for securing the friction plate 6. A seventh threaded hole 24 is provided between two second through holes 16 on a set of opposing sides of the outer side surface of the outer column 8. The seventh threaded hole 24 is used to secure the decorative cover 7. Four second threaded holes 15 are provided at one end of the outer side surface of the outer column 8 for securing the friction plate 6.
