Why focus on post-surgery patients?

Recovery doesn’t end when a patient leaves the hospital, especially when they return to a multi-level home with limited strength.

Many mobility devices are designed for flat hospital floors. Our design prompt asked us to improve mobility and autonomy for post-surgery patients, so we focused on the exact group that struggles most with stairs, partial weight bearing, and dependence on caregivers.

Clinical rationale

Which patients actually need stair-friendly walkers?

Lower-extremity surgeries

Hip replacement, knee replacement, femur/tibia fracture repair.

Spine procedures

Spinal fusion, laminectomy, discectomy, limited bending & lifting.

Abdominal/thoracic ops

Patients tire quickly and need stable support on home stairs.

Older adults

Reduced grip/arm strength makes lifting a walker on stairs unsafe.

Where current walkers fail

Walkers are great on flat surfaces, not on elevation changes.

How QuinLift addresses this

We convert the support force patients already use into stair assistance.

1. Penta-wheel design

As the patient leans down and pushes forward, the wheels help convert that forward pushing force into stair climbing power. No need to lift the whole walker.

2. Designed for home stairs

Tuned for typical indoor stair heights so the motion is predictable and repeatable for recovering patients.

3. Safety-aware

Contains a back-leg adjustment mechanism to prevent the walker from tipping backwards when the user is on a stair. Additionally, in design, includes a stair safety lock to prevent rollback between steps, matching the autonomy goal of the original prompt.
