摘要： Disclosed herein is a robotic ankle foot prosthesis that replicates the key biomechanical functions of the biological ankle and toe joints while matching the weight, size, and battery life of passive microprocessor-controlled prostheses. A single actuator powers the ankle and toe joints. The mechanism maximizes the mechanical energy regeneration during walking while imitating the physiological features of energy injection by way of the ankle joint and energy dissipation by way of the toe joint.

摘要： A device is provided to allow adaptation of a prosthetic or robotic foot in the medial-lateral direction, including pronation and supination of the foot using a series of articulations. Articulations are permitted in the disclosed device due to linkage systems positioned at various locations of the prosthetic foot. In particular, the device includes multiple connected linkage systems each including upper and lower portions with an articulating contact surface designed for load carriage and stability. The point of contact between the contact surfaces of each linkage system comprises the position-dependent instantaneous center of rotation of the upper portion with respect to the lower portion. The device also includes a platform coupled between the linkage systems and a base.

摘要： A prosthetic foot has a frame, a forefoot keel, a heel keel, and an adjustable spring member. The frame couples to a prosthetic leg. The forefoot keel includes a first resilient substrate extending from the frame to the anterior end of the foot. The heel keel member includes a second resilient substrate extending from the frame to the posterior end. The first and second resilient substrates are load bearing substrates for a walking human. The adjustable spring member includes a third resilient substrate and a brake. The third resilient substrate has a first end directly or indirectly coupled to the brake, and a second end coupled to the forefoot keel proximate to the anterior end. The third resilient substrate extends through or around the first resilient member and the second resilient member. The brake provides resistance to the travel of the first end of the third resilient substrate in the superior direction.

摘要： An ankle-foot prosthesis comprises a foot structure having a foot keel leaf spring, a heel leaf spring, and an upper J leaf spring above the keel leaf spring. An ankle bearing block is mounted to the keel leaf spring and a shank shell is mounted to the ankle bearing block. A shank interface mounts to the shank shell. A processor controlled active element extends along an axis between the shank shell and the upper leaf-spring.

摘要： The present disclosure relates to variable recruitment actuator systems and related methods. In one embodiment, a variable recruitment actuator system utilizes a central hydraulic pump, an accumulator, a plurality of variable recruitment actuators, and a pressurized reservoir of hydraulic fluid to provide highly efficient hydraulic regenerative energy harvesting in systems requiring both eccentric and concentric motion. In another embodiment, a powered prosthetic or orthotic device, or a legged robot, utilizes a system as previously described to capture energy from the eccentric motion of the knee joint to provide concentric motion of both the knee and ankle joints later on in a gait cycle.

摘要： A vacuum pump may be used to attach a prosthetic and/or orthotic device to a residual limb. The vacuum pump may be in line below a socket of a residual limb. The socket may be a portion of the prosthesis that accepts the residual limb. The vacuum pump may generate a vacuum condition between the prosthesis and the residual limb. Generally, a vacuum condition may be generated between a socket and the residual limb. The residual limb may be covered with a sock, elastomeric liner, or sheath covering the limb. The vacuum condition may positively attach the prosthesis to the residual limb without the need for straps, retaining pins, or suction type vacuum which do not use a vacuum pump.

摘要： A foot cover for a prosthetic foot can allow a user to more easily remove the foot cover when the foot cover needs to be switched out or cleaned. The foot cover can have a hinge near a heel end of the foot cover. The hinge can allow a user to rotate a section of the foot cover to increase the size of the opening so that the foot prosthetic can be inserted into or removed from an inner cavity of the foot cover. The foot cover can be an easily separable two-part foot cover, the two parts coupled together with magnets or another mechanical fastener.

摘要： The invention relates to a method for controlling a prosthesis or orthesis of the lower extremity, which prosthesis or orthesis comprises an upper part (10) and a lower part (20) that is connected to the upper part (20) via a knee joint (1) and is mounted so as to be pivotable relative to the upper part (10) about a joint pin (15); wherein an adjustable resistance device (40) is situated between the upper part (10) and the lower part (20), by means of which resistance device a flexion resistance (Rf) in an early and middle standing phase is modified, during walking, on the basis of sensor data, following initial heel contact up to the middle standing phase; wherein, following the initial heel contact, the flexion resistance (Rf) is increased to a value at which further flexion is blocked or at least slowed; wherein the progression over time of the flexion resistance increase and/or the maximum achievable flexion angle (Af) is modified on the basis of the inclination of the ground or a height difference (ΔH) to be overcome.
