A control unit system. The system includes a control unit which includes a control unit charging interface, at least one magnet located proximate to the control unit charging interface, at least one actuator, a detachable manifold including at least one magnet, fluidly coupled to the at least one actuator, a pump connected to the at least one actuator for causing actuation thereof, and a control system for controlling the pump, wherein the control system controls the pump to actuate the at least one actuator at least in response to a signal received by the control system. The system also includes a recharging device configured to receive the control unit, the recharging device including a reed switch, wherein when the magnet in the control unit is located proximate to the reed switch, the switch is activated.

A system for powering a prosthetic arm is disclosed. The system includes at least one internal battery located in the prosthetic arm, at least one external battery connected to the prosthetic arm, and a master controller configured to connect either the at least one internal battery or the at least one external battery to a power bus to power the prosthetic arm.

Prosthetic devices, such as prosthetic hands (including, e.g., bionic prosthetic hands controlled by myoelectric signals and/or equipped with force sensors for feedback) can utilize a modular design to simplify assembly and repair. In some embodiments, low-cost additive manufacturing techniques are employed, e.g., to create prosthetic device parts with complex interior geometries and/or functionally integrated components.

Systems and methods are described herein for a prosthetic device that includes a premade outer shell socket with an inner surface contour. A prosthetic insert socket is manufactured via a manufacturing process, such as three-dimensional printing, to have an outer contour that corresponds to the inner surface contour of the premade outer shell socket. The prosthetic insert socket is manufactured to have an inner contour that corresponds to a residual limb surface contour of a patient.

The prosthetic device is a general use prosthetic device for shower and daily mobility applications which provides a semi-custom fit. The semi-custom fitment of the leg height and anatomical sizing of the affected leg amputation are possible via configurable liner pads which can be interchanged within the support socket based on need by the wearer. The device is capable of being used on either the left or right leg with no modifications to the device and can be secured to the wearers residual limb via a friction fit between the socket liner and limb. Furthermore, an ergonomic handle and grip provides another point of control for the device to assure safety and security.

A dynamic support system includes a control system for controlling inflation and deflation of at least one actuator having an inlet connectable to the a control unit of the dynamic support system. The control unit may be in communication with a sensor and may control inflation and deflation of the at least one actuator in response to information provided by the sensor.

A prosthetic connector system for use with a prosthetic socket having a distal end includes a plate defining a plurality of holes and attachable to the distal end of the prosthetic socket. A component is removably attachable to the plate via the plurality of holes and arranged to connect a prosthesis to the prosthetic socket. The plate defines an outer periphery having an asymmetrical configuration contoured to substantially correspond to at least a portion of the component when the component is attached to the plate via at least some of the holes.

An under-driven prosthetic hand with a self-adaptive grasping function is provided, which belongs to the field of medical equipment. The prosthetic hand simultaneously controls four fingers to implement bending and stretching movements by a first motor through structural designs of a prosthetic hand body, a finger transmission module, an inter-finger transmission module, and a thumb driving module, and limits the transmission torque between the motor and screws using a damping shaft and in cooperation with the telescopic characteristic of a telescopic component. On the one hand, mechanical damage to the prosthetic hand structure due to excessive torque outputted by the motor can be prevented. On the other hand, the self-adaptive grasping function of the prosthetic hand can be implemented. The disclosure can also effectively solve issues such as excessive volume or mass of the prosthetic hand, complicated control system, and low operation precision.

An adjustable prosthesis system for a residual limb includes: an adjustable outer shell surrounding the residual limb having a plurality of overlapping flaps, a top opening along a top edge extending around the outer shell, a bottom having a bottom edge opposite the top edge and extending around the bottom, a first side, and a second side having an adjustable width, and a plurality of adjustable overlapping side ends, some of which overlap and some do not, extending from the top edge to the bottom edge; a base adjacent the bottom of the outer shell and connected to it; and a closure component attached to the outer shell to compress the residual limb. Tightening the closure component applies a pulling force to at least one of the first side and the second side, thereby causing a reduction in width of a discontinuity and increased overlap of the side ends.

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.
