Problems solved by technology

The height of its armrests, knee pads, and back cushions cannot be adjusted, and cannot be adjusted according to specific situations such as the height of the patient; secondly, it is inconvenient to install, and specifically, it requires more parts (sliding rods, knee pads, back cushions, clips, etc.) Hinge, chute, hinge, automatic pin), inevitably, its installation steps are cumbersome and difficult to disassemble; when the patient recovers from the injury to a certain extent or the injury is mild, it may no longer need to support the knee during activities with crutches, However, the disassembly process is cumbersome, and the knee support structure is difficult to disassemble
