Overview

Prosedo 3R31
Locking knee with flexion resistance sitting assist

The Prosedo 3R31 features a hydraulic flexion resistant sitting assist. The hydraulic can be adjusted based on patient weight and needs.  After disengaging the lock, progressive flexion resistance will support the patient while lowering into a seated position. This can help provide balance and reduce strain on the patient’s sound side.

  • Manual lock - Manual lock knee with unique release function. Disengagement of the lock when partially loaded is possible.
  • Optional lock release - Optional disengagement of the lock via lock release button which is located underneath the blue front cap.
  • Adjustable hydraulics - New to this segment of low mobility products: a hydraulic controlled high and progressive flexion resistance to help provide balance while patients are lowering into a chair.
  • Proximal connection - Prosedo is available with two proximal connection variants: a pyramid adapter or a threaded connector for fittings of longer residual limbs.
  • High maximum body weight - Lightweight design (600 g) with a high weight limit (275 lbs / 125 kg).
  • Tube clamp Ø 30 mm - Pylon is included in scope of delivery.

Benefits for the Patient     

  • Smooth unlocking to help patients more safely lower into a chair and reduce strain on their sound side.
  • Small, lightweight design reduces overall weight of prostheses.
