Why Hydraulics?

Lower limb amputees can face health issues long after amputation, and it is the consideration and management of these issues that are crucial to the sustained health of every patient.

We believe long-term musculoskeletal health depends on the replication of the dynamic and adaptive qualities of natural limb movement. The engineering of nature is the prime source of inspiration at the heart of our biomimetic design philosophy where the development of award-winning prostheses is focussed on the long-term health and wellbeing of every amputee.

The human ankle and foot have four main rocker points that allow us to walk efficiently. By considering the natural function of the foot and replicating its structure through a unique combination of design elements, Blatchford Biomimetic Hydraulic Technology provides a natural and fluid walking experience.

The human ankle foot complex contains 28 bones and 33 joints that work in sequence to provide balance, stability and a seamless walking experience. Blatchford hydraulic ankles respond to the design specifications that natural movement dictates, fine-tuning joint position to align the body for optimum posture and comfort.

By continuously adjusting to absorb and release energy, our hydraulic ankles allow for an efficient roll-over, remaining perfectly aligned with the user for the next step to help reduce the risk of falls.

Biomimetic Design Philosophy

Energy Absorption: Hydraulics absorb energy to minimise tissue stress

Biomimetic Self-alignment: To fine tune joint position for improved posture, gait symmetry and reduced socket interface stress

Adjustment and Control: Fine tuned to the user’s requirements

Viscoelastic: Spring and damper reduce the rate of loading, removing force from the system and therefore the limb
