This application discloses a dexterous hand. The dexterous hand uses the anatomical structure of human hands for reference. The joints adopt dual-actuator antagonistic drive, which gives consideration to both compliant operation and robustness. The tendon joint and tendon sheath fixator are used for easy disassembly of hands and wrists. The metacarpophalangeal joints of each finger have the DOF of circumduction of, so that the fingers can automatically adapt to the complex surface. The axes of the multi-degrees of freedom joints are orthogonal, which is beneficial to control and motion planning calculation. The dexterous hand is ideal for handling objects of complex shape smoothly, facilitating production, disassembly and maintenance.

The present disclosure relates to an anatomically aligned prosthetic ankle with a passive assist and associated methods. The prosthetic ankle includes a talus movably coupled to a tibia section by a connector about which the talus is pivotal such so during locomotion by a user of the prosthetic ankle. The passive to assist provides a selected dorsi-flexion force to aid in the push-off or pre-swing phases of gait for the user.

An artificial hand suitable for use in humans and robots, includes at least one finger member and at least one thumb member, which is actuated by bending the at least one joint by the motor unit; said finger member comprising one proximal and one middle phalanx consisting of two subparts each, said thumb member comprising one proximal and one middle phalanx consisting of two subparts each, and said two-piece proximal and middle phalanges comprise at least one connection means in grooves extending longitudinally therein, increasing lengths of said proximal and middle phalanges by enabling the two pieces to be set apart from each other.

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 system includes a movable joint defining at least one gap, and at least one spacer unit positionable in the at least one gap. The at least one spacer unit includes a resilient element that is controllably deformable to vary a thickness of the at least one spacer unit to fill the at least one gap, and to reduce the likelihood of the at least one spacer unit interfering with relative movement between components of the movable joint. The at least one material forming the resilient element is compressible in a first direction with little or no expansion in a second direction normal to the first direction.

Prosthesis for at least one cut-off finger resulting in a stump at the height of the proximal, middle and/or distal phalange, or in a finger with missing stump. The prosthesis from a modular hinged mechanism allowing for a self-return flexion movement and the activation of said mechanism from at least one force applied to any point of a plane on said mechanism. A prosthesis for a hand with missing stumps is also provided from the wrist movement providing a range of operation greater than the art, wherein said flexion is activated from an extension movement of the wrist.

A system and method for an artificial tendon or muscle driven prosthesis that may include an articulating prosthesis with a set of actuation points; an artificial tendon system, the artificial tendon system being integrated with the articulating prosthesis and comprising an external tendon actuation interface coupled relative to at least one actuation point of the set of actuation points, and the artificial tendon system further comprising integration with a musculoskeletal-integrated internal artificial tendon; and an osseointegration abutment through which the artificial tendon system couples the external tendon actuation interface to the musculoskeletal-integrated internal artificial tendon integration and can implement an infection mitigation system.

A prosthetic digit usable with capacitive panels is provided. The digit includes at least one conductive layer surrounding the body of the digit, and a non-conductive sealing layer around the conductive layer preventing direct external contact of the conductive layer with the capacitive panel. The digit may have a conductive tip pad to create a series capacitive pathway between the conductive layer of the body and the electrodes of the capacitive panel. Using the digit with a capacitive panel does not require a direct conductive pathway, e.g., a pathway between the capacitive panel and the structure of the device, the user's skin, or metallic sink.

A prosthetic knee can include a variable-torque magnetorheological (MR) actuator assembly or braking system, a frame and an electronics assembly or system that also serves as a mount for the knee actuator and facilitates in monitoring and controlling the operation of the knee actuator. The prosthetic knee system advantageously provides resistive forces to substantially simulate the position and motion of a natural knee joint during ambulation and/or other locomotory activities performed by the amputee. The prosthetic knee can be enclosed in a waterproof compartment. An outer cover can be configured to fit around the waterproof cover of the prosthetic knee.

A traction system for an ambulatory support such as a prosthetic foot blade or a crutch includes a sole plate, a latch assembly, and a strap. The sole plate is couplable to a distal end of the ambulatory support to extend under a bottom side of the ambulatory support and a latch assembly. The latch assembly includes a front catch and a rear catch both fixable at a top side of the ambulatory support with the front catch nearer to the distal end of the ambulatory support than the rear catch, and a lever having a front end and a rear end, the front end releasably latchable to the front catch and the rear end releasably latchable to the rear catch when the lever is pivoted about the latched front end. The strap is secured to the lever and to the sole plate.
