Crutch apparatus and method for designing and fabricating

摘要

A crutch includes a grip and a forearm support that are coupled to an elongated member that extends from the forearm support to the ground. The inner surface of the forearm support can correspond to a digital representation of a forearm of the patient and the outer surface of the hand grip can correspond to a digital representation of a palmar surface of the patient's hand in at least a partially closed position.

主权项

1. A crutch comprising:
a hand grip; and a forearm support having an elongated body, a first curved member rigidly coupled to the elongated body and a second curved member rigidly coupled to the elongated body, wherein the first curved member is attached to a proximal portion of the elongated body and the second curved member is attached to a separated location near a central portion of the elongated body to define an elongate inner surface of the forearm support, wherein the first curved member and the second curved member are oriented in a spiral configuration that is adapted to surround a forearm of a patient and an inner surface of the forearm support is adapted to match dimensions and surface contours of the patient's arm; and the hand grip being attached adjacent to the forearm support wherein the hand grip is perpendicular to the elongated body.
