A control system for control of a prosthetic device having a plurality of actuators receives an orientation signal indicative of a desired movement. The control system evaluates whether the prosthetic device may move as desired with a current angle of rotation and commands at least one actuator to move the prosthetic device as desired by maintaining the current angle of rotation or by adjusting the angle of rotation if the prosthetic device cannot move as desired with the current angle. The control system may alternate between commanding a first subset of actuators and a second subset of actuators each time the orientation signal is indicative of a neutral position. The control system may include a position sensor and a compliance sensor and may command at least one actuator based on a combination of positional control using the position sensor and force control using the compliance sensor.

A prosthetic device includes a prosthesis wall, at least one display carried by the prosthesis wall in spaced-apart relationship to the at least one display and interfacing with the at least one display, the control module adapted to present at least one image on the at least one display.

An adjustable counterbalance mechanism for a prosthetic elbow includes a torsional spring disposed in a housing structure coaxially to an axis of rotation of a forearm portion and a cord and pulley arrangement which includes a first pulley, a second pulley and a link member attached to a fixed member structure. The first pulley is attached to a second portion of the spring and connected to the second pulley by a first cord. The second pulley is pivotally attached to the housing structure and connected to the link member by a second cord. The cord and pulley arrangement is configured to transfer a moment of force due to spring force to the forearm portion to counteract the torque of a forearm due to gravity as the angle of the forearm portion changes relative to the upper arm portion.

The invention relates to a method for setting up a controller of an orthopedic device with at least one motor drive, which is applied to a body part of the patient and connected to sensors that record control signals of the patient, said method including the following steps: outputting an optical, acoustic and/or tactile representation of an actuation of a limb as a request for the patient to carry out said actuation; detecting control signals that are produced by the patient as a voluntary reaction following the request, assigning the detected control signals to the implemented actuation and to a function in which the at least one motor drive is activated, deactivated or reversed in terms of its direction of rotation, and outputting the detected control signals and/or the function following the assignment to the respective function.

An upper limb prosthetic device may comprise a hybrid-drive prosthetic device that includes one or more actuators fixed to a first arm portion and one or more cables extending from the one or more actuators along one or more cable paths defined through the first arm portion and a second arm portion to a terminal device/device assembly, where the one or more cables are configured to be actuated by the one or more actuators and are further configured to be actuated by pivoting the second arm portion toward the first arm portion, Alternatively, or additionally, the upper limb prosthetic device may comprise a modular prosthetic device that includes a modular terminal device assembly with removably coupled first, second, and third modular links configured to control the respective yaw, pitch, and roll of an end effector (e.g a prosthetic hand, a tool, an instrument or any other attachment).

A socket may be for coupling a prosthetic upper extremity to a residual limb of a user. The socket may include a proximal socket portion and a distal socket portion coupled to the proximal socket portion by a polycentric joint. The polycentric joint may include a plate having a first end coupled to the proximal socket portion via a first fastener, and a second end coupled to the distal socket portion via a second fastener. The proximal socket portion may be rotatable relative to the distal socket portion about a first axis passing through the first fastener and about a second axis passing through the second fastener.

Various examples are provided for modular prosthetic devices and their use. In one example, a device includes a chassis assembly including a joint portion; and an interchangeable module that can be removably attached to the chassis assembly. The interchangeable modules can be configured for use in a wide variety of applications. The interchangeable modules can be quickly exchanged for different activities.

Low-cost prosthetic apparatus, methods, kits, and systems with improved force transfer elements are disclosed. For example, the prosthetic apparatus may comprise: a plurality of first components manufactured from a first material to define 3D shapes with exterior surfaces resembling digits of a human hand; and a plurality of second components manufactured from a second material to define 2D shapes that are rotatably engageable with the 3D shapes to define force transfer elements operable to close the digits around an object responsive to a pull force applied to the force transfer elements, wherein the first material is different from the second material. Methods for manufacturing and assembling prosthetic apparatus also are disclosed along with related kits and systems.

A below-elbow prosthetic arm assembly includes a hand; an arm connected to the hand; a cylinder connected to the arm; and a string connected to the rear end of the cylinder. To start using the prosthetic arm, the user's amputated upper limb is enclosed by the cylinder and tied thereto with a string. The below-elbow prosthetic arm assembly further includes an expansion kit adapted to meet the user's needs in daily lives, learning and sports. The expansion kit is directly fitted to the hand. Function expansion is achieved without removing the hand. Therefore, the below-elbow prosthetic arm exhibits enhanced ease of use and minimizes the user's financial burdens which might otherwise arise from ordering customized prosthetic arms for use in different activities.

A prosthetic arm apparatus comprising a plurality of segments that provide a user of the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connectable to one another and connectable to a harness mount that may be adorned by the user. Each segment of the plurality of segments provides a portion of the movement capability, enabling the plurality of connected segments connected to the harness mount to provide substantially the same movement capability as that lacking in the user.
