AI Technical Summary
The height adjustment of existing postoperative ambulation devices requires turning each bolt individually, which is difficult for patients to adjust without family members present. Furthermore, the devices lack a positioning function during use, leading to inconvenience and increased physical exertion.
The design incorporates positioning holes, mounting plates, and limiting mechanisms, along with sliders, positioning mechanisms, and connecting plates, to achieve rapid height adjustment and tilting functions. Patients can adjust the height themselves and prevent the assistive device from moving when resting.
It enables quick height adjustment without the need for family members' assistance, reducing physical exertion and improving ease of use and rest effectiveness.
