Upper Extremity Pre-Prosthetic Device

This prosthetic device is for patients who have undergone above the elbow amputations of their arms. The invention is a relatively simple device and incorporates an “elbow” joint and cable system which allows the patient to flex and extend the arm portion of the device. Various tools (e.g., toothbrush, fork) can be attached to the arm for use by the patient. The relative simplicity of the invention is a virtue, allowing it to be fitted to and used by a patient soon after surgery, in contrast to the requirement for complete healing before fitting a final prosthesis. The device allows the patient to perform self-care and other activities with less reliance on family and nursing staff. An important aspect to recovery of these patients is the demonstration of an ability to function independently. This invention offers substantial benefits for care of upper extremity amputees. The device can be custom fabricated from generally available low-cost components within 1 to 1.5 hours. It is designed for gentle attachment to the limb, allowing use while the limb is still healing. The device provides a significant increase in the ability of patients with bilateral above the elbow amputations to care for themselves and undertake other daily activities. According to the disclosure, there are several devices that can be used by patients with below the elbow amputations, but none that can replace the elbow as the current device does. Benefits: Requires minimal gross body movement to function Can be used the day after a surgery Flexible cuff adjustment for arm size changes Performs "Hand to mouth" and "reaching" tasks Can be fabricated in any rehabilitation clinic No other temporary prosthesis with elbow is available Easy to commercialize as a kit Low Cost
