The invention relates to an automated hand, such as a prosthetic hand. In one form, the automated hand may be fluid compatible. In one form, the automated hand may comprise features to reduce the risk of harm to motors and/or other sensitive components of the hand when subject to an impact. In one form, the hand may comprise a wrist joint configured to allow the hand to curl and flex and/or to rotate. In one form, one or more digits of the hand may be individually controlled. In one form the hand may include a thumb rotation locking mechanism. In one form the hand may be provided with removable grip plates. In one form, the hand may be configured for use as a training hand.

A prosthetic ankle joint for a prosthetic foot attached to a base assembly. A linkage assembly provided between the base assembly and a torque bracket including an adapter unit disposed at top of the torque bracket to provide a connection to a lower tube-shaped clamp fitted over a pilon. The pilon extends upward to a second tube-shaped clamp connected to a lower portion of a socket receiving a residual limb of an amputee.

Features for prosthetic digits are described. The digits mimic natural fingers by having multiple articulating segments, for example three, that can rotate varying amounts. Rotatable and/or linearly expandable mechanical links are configured to provide the digit segments with multiple degrees of rotational freedom. The digit may have an actuator that outputs linear actuation to cause rotation of the digit segments. The digit may have an expandable proximal link to allow for variable relative rotational positions of the segments. Middle and/or distal digit segments may fully rotate independent of rotation of a proximal digit segment. The rotated digit may thus fully surround and grasp small or large objects, objects with irregular outer contours, etc.

An orthopedic device for the orthotic or prosthetic provision of a patient is provided. The orthopedic device includes a knee joint, which has a proximal upper part and a distal lower part arranged pivotably thereon, an ankle joint, a pivoted foot part which can be fastened distally to the ankle joint, and a shin part arranged between the ankle joint and the knee joint. The upper part of the knee joint or a thigh part fastened thereto that can be attached to the patient's body and is coupled with the foot part by means of a force transfer device, which causes a plantar flexion of the foot part when a knee is flexed.

A prosthetic device for engaging a residual limb includes a plurality of elongate counters configured to receive at least a portion of the residual limb within a volume defined by the plurality of elongate counters. Each respective elongate counter is configured to counteract forces applied to the residual limb via the prosthetic device. The prosthetic device also includes a socket and a selective adjustment system, and may include an independent counter engaged with the socket. The socket is configured to engage with the residual limb, and may include a lower textile socket coupled to the plurality of elongate counters and an upper textile socket coupled to the lower textile socket. The selective adjustment system is configured to secure the prosthetic device to the residual limb and to provide selective adjustment of compression of the socket and the plurality of elongate counters around the residual limb.

Various embodiments of the present invention generally relate to prosthetic partial finger designs that can mimic the last two joints of the finger. Some embodiments include a proximal phalange, a distal phalange coupled to the proximal phalange, and a knuckle track (e.g., formed in an arc). The knuckle track can be moveably coupled to the proximal phalange an may include multiple teeth formed on which the proximal phalange slides along. A ratcheting mechanism can contact the multiple teeth to allow sliding in only a first direction while the ratcheting mechanism is engaged. Some embodiments include a release mechanism (e.g., a button) configured to disengage the ratcheting mechanism from the multiple teeth to allow the distal phalange to slide in a second direction. In some embodiments, the device may include a spring-back capability that automatically extends the finger after reaching full finger flexion, enabling one-handed use.

An artificial wrist comprising including a static body adapted to be bound to a support; a movable body adapted to be bound to an end effector; and a junction block defining an axis of rotation between the static body and the movable body and comprising including a cable suitable to be moved by mutual rotation of the bodies and around the axis of rotation, and elastic member placing the cable under tensile stress and working in opposition to the movement of the cable so as to define a rest position in which the cable and the elastic member exerts a zero resulting torque on the bodies and, and an activation position in which they exert a non-zero resulting torque on the bodies and, bringing the bodies and back to the rest position.

The invention relates to an orthopedic joint device having an upper part and a lower part which is hinged about a pivot axis to said upper part, having a flexion moment-controlled retainer device that is positioned between the upper part and the lower part, blocks a flexion and releases the flexion when a predefined flexion moment is exceeded, wherein a control element is associated with the retainer device and is coupled to a delaying element.

The invention relates to a prosthetic foot with a foot part 2 and a lower leg part 4 that is connected to the foot part 2 such that it can be pivoted about a pivot axis 6 and that can be locked in various pivot angles relative to the foot part 2,the connection between the lower leg part 4 and the foot part 2 having a clearance in the pivot direction when the foot part 2 is locked on the lower leg part 4, the prosthetic foot having at least one friction element 14 arranged between the foot part 2 and the lower leg part 4 and applying a frictional torque that counteracts a pivoting of the foot part 2 relative to the lower leg part 4 when the foot part 2 is locked relative to the lower leg part 4.

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.
