The invention relates to the technical field of correction instruments, in particular to a
pressure sore prevention type orthopedic
lower limb lifting auxiliary device which comprises a base with a slope, a first
traction frame is rotationally connected to the outer wall of the slope of the base, and a second
traction frame is rotationally connected to the end wall of the end, away from the base, of the first
traction frame. A guide groove is formed in the outer wall of the end, close to the first traction frame, of the second traction frame. Through the arranged
pressure sore prevention mechanism, after a detection value reaches a threshold value and lasts for a period of time, a
pressure sensor drives a second electric push rod to stretch or contract through a controller
signal, so that the second electric push rod pushes a floating frame to slide along a second traction frame, and the floating frame drives a roller
airbag to move synchronously; therefore, the contact part of the roller air bag and the shank of the patient is changed, the effect of monitoring the pressed area of the
lower limb of the patient in real time is achieved, active intervention is conducted by changing the pressed position, and the
pressure sore prevention effect is further improved.
