AI Technical Summary
In existing lower limb joint replacement surgeries, manual adjustment of the patient's lower limb angle is required, which is inconvenient and affects surgical efficiency.
A surgical aid device for lower limb joint replacement surgery was designed, which uses an electric telescopic rod and a torque motor to drive the sliding, lifting, and swinging of the foot and leg baffles, and achieves automatic adjustment through a switch button.
This technology enables automatic adjustment of the patient's lower limb angle without removing the surgical drape during surgery, improving operational convenience and surgical efficiency.
