The utility model relates to the field of postoperative care devices, in particular to an adjustable plastic hip joint fixing pillow which comprises a supporting mechanism, the supporting mechanism comprises a first supporting plate and a second supporting plate, and the first supporting plate and the second supporting plate are platy. The tops and the bottoms of the outer walls of the first supporting plate and the second supporting plate are fixedly connected with bearing plates, and the bearing plates are of elastic metal plate structures. Through the supporting mechanism, the distance between the two groups of bearing plates can be adjusted by adjusting the distance between the first supporting plate and the second supporting plate, so as to adapt to the distance between the legs of different patients; through the L-shaped first supporting plate, the situation that the hip joint of the patient bends by more than 90 degrees due to excessive curl-up of the patient is avoided.

This invention discloses a passive transport exoskeleton based on a variable stiffness gravity compensator and its usage method. The passive transport exoskeleton includes a back strap assembly, a hip fixation assembly, a back linkage assembly, and a thigh actuator assembly. An energy recovery assist device is fixedly connected to the bottom end of the back linkage assembly, located to the side of the hip fixation assembly. The energy recovery assist device includes a bending assist device fixedly connected to the back linkage assembly, a walking assist device driven by the top end of the thigh actuator assembly, a clutch device coaxially mounted on the power transmission shaft of the walking assist device, a pulley system driven by the bending assist device, and a Bowden rope device connecting the clutch devices on both sides. This device requires no external energy supply, relying on its mechanical structure to achieve energy storage, release, and recovery and reuse of negative energy. It can precisely adapt to human gait, match appropriate assist timing, effectively assist hip joint movement, and reduce joint load and human energy consumption.
