The invention provides a supine-position
knee joint pressure
simulation device. According to the invention, double lower limbs of a patient are placed on a bottom plate; the end part of a tension device is fixed; a tension adjusting device is adjusted and combined with a pressure measuring device to control the pressure of a pressure plate; the generated pressure is equal to the pressure generatedby the weight of a patient to knee joints in a standing state, the pressure is applied to the soles of the patient through the supporting plate, the supine
knee joint pressure
simulation is completed, then X-
ray films are shot, and the double-lower-limb full-length X-
ray films of the patient in a
load bearing state can be obtained. According to the supine-position
knee joint pressure
simulation device, the pressure of the pressure plate is horizontally adjusted, the pressure is monitored through a tension and compression sensor; the pressure of the weight of a patient on knee joints is simulated, the
load bearing state of the two lower limbs of the patient in a
supine position is simulated, which solves the problem that existing equipment cannot
shoot the full-length X-
ray films of the two lower limbs of the patient in the
load bearing state, the device provides a correct guidance method for a
lower limb operation, and is simple in structure and convenient to operate.
