Extension Assist Hip Joint for Low Functional Users：

Low-function amputees: "Users whose postoperative recovery period and daily activities primarily consist of indoor walking and short outdoor activities, who have weak muscle strength and rely on prosthesis stability."

Pathology-specific users: "Patients who have undergone hip dislocation or hemipelvectomy and require a customized prosthesis to fit their pelvic structure and require ease of transition from standing to sitting."

Weight Compatibility: "Adult users weighing ≤100 kg do not need to worry about prosthesis damage due to insufficient weight bearing."

Automatic Locking Hip Joint for Hip Dislocation:

Daily Living: "When standing up in the morning, the automatic locking function quickly secures the joint to prevent stumbling. When sitting down, manual unlocking eliminates the need for assistance, promoting independence."

Rehabilitation Training: "During gait training at a rehabilitation center, the adjustable flexion and extension angles accommodate different training stages (e.g., initially walking at a small angle, then gradually increasing the range of motion)."

Home Care: "Family members no longer need frequent assistance with standing and sitting down, reducing the caregiver burden and allowing users to complete daily activities independently and with greater dignity."

The single-axis assisted extension prosthetic hip joint is designed for low-function lower-limb amputees (such as those in postoperative recovery, those with weak muscles, and those who rely on prosthesis stability).
