LOWER LEG PROSTHESIS WITH IMPROVED ROLLOVER

摘要

A foot prosthesis (100) having improved rollover and stability. The prosthesis (100) includes a first plate (130) and a mounting block (140) having a mounting portion configured to be coupled to a user of the prosthesis (100), an attachment portion and a gap portion (147), with the mounting block (140) attached to the first plate (130) at the attachment portion with a gap (147) between the mounting block gap portion (147) and the first plate (130). Also included is a resilient element (150) positioned at least partially within the gap (147), the resilient element (150) configured generally to dissipate stress in the first plate (130) and control deflection between the first plate (130) and the mounting block (140). The mounting block (140) may be substantially rigid with the area of the first plate (130) attached to the mounting block (140) becoming substantially rigid while the remainder of the first plate (130) is at least partially flexible. The resilient element (150) may be interchangeable to adjust performance of the prosthesis (100).
