Abstract: A three-dimensional (3D) image dynamic correction evaluation and auxiliary design method for orthotics includes the following steps. 3D scanning information of the human body is obtained. A plurality of 2D images of the human body is obtained for identification, and the pixel values of the 2D images are calculated so as to synthesize an original 3D spine curve. The 2D images of the human body and the 3D scan information are synthesized. An image deformation prediction and correction method of body shape is used to generate a deformed body shape of the human body. A spine material properties and mechanical model prediction method is used to predict parameters of the position, direction and magnitude of the force applied by an orthotics to the human body according to the deformed body shape.

Abstract: A limb prosthesis including a palm, a forearm, an upper arm, an elbow joint and a wrist joint is provided. The palm has a first pivot and a first lock set. The upper arm has a socket. The elbow joint connects the forearm to the upper arm. The wrist joint includes a first connecting rod connected to the forearm. The first pivot rotatably penetrates through the first connecting rod. The first lock set is locked to the first pivot. A first wedge surface of the first lock set contacts a second wedge surface of the first connecting rod. By adjusting a distance between the first lock set and the first pivot, a magnitude of a forward force between the first wedge surface and the second wedge surface is adjusted, such that the palm is fixed relative to the first connecting rod or rotatable around an axial direction perpendicular to an extending direction of the forearm.
