    • A system and method for fabricating a thermoplastic prosthetic limb socket from a thermoplastic preform cone involves the steps of: obtaining a digital or physical positive representation of a patient's residual limb; determining a desired thickness for the thermoplastic socket; selecting a thermoplastic preform cone; calculating the dimensions of a proximate extension to be added to the proximate end of the digital or physical representation of the patient's residual limb based upon the dimensions of the patient's residual limb, the dimensions of the preform cone, and the desired thickness of the thermoplastic socket; forming a positive socket mold based upon the combined dimensions of the patient's residual limb and the extension; heating the preform cone; and stretching the preform cone over the positive cast. Preferably the method is performed on a CAD tool. The processing unit in the CAD tool has access to the dimensions of the residual limb, the desired thickness of the socket and the dimensions of the preform cone; and is thus able to compute the dimensions of the proximate extension based upon a set of algorithms stored in the form of a software package (or program) accessible and executable by the CAD's processing unit.
    • 一种用于从热塑性预成型锥体制造热塑性假肢支座的系统和方法包括以下步骤:获得患者残肢的数字或物理正面表现; 确定热塑性插座的期望厚度; 选择热塑性预制棒锥体; 基于患者残肢的尺寸,预制锥的尺寸和热塑性插座的期望厚度来计算要添加到患者残肢的数字或物理表示的近端的邻近延伸部的尺寸 ; 基于患者残肢和延伸部的组合尺寸形成正插座模具; 加热预成型锥; 并将预制棒锥体拉伸在正极上。 优选地,该方法在CAD工具上执行。 CAD工具中的处理单元可以访问残肢的尺寸,插座的期望厚度和预制锥的尺寸; 并且因此能够基于以可由CAD处理单元访问和执行的软件包(或程序)的形式存储的算法集合来计算邻近扩展的维度。

    • Disclosed is a shape data processing method illustratively for use with a CAD,CAM (computed aided design/ computer aided manufacturing) system. The method involves measuring the volume of a target product based on the shape data of that product. In operation, a virtual projection surface is established for the target object to be measured. The surface of the object is divided into small regions. A column portion is formed as an extension from each small region to the projection surface. The volume of the column portion is measured for each small region. The measured volumes are accumulated in accordance with the orientation of the normal vector to each small region. This method allows the volume of the target object to be measured easily and with precision even if the shape thereof is complex.

    • Disclosed is a shape data processing method illustratively for use with a CAD/CAM (computer aided design/computer aided manufacturing) system. The method involves measuring the volume (VM) of a target product (M) based on the shape data of that product. In operation, a virtual projection surface (K) is established for the target object (M) to be measured. the surface of the object is divided into small regions (S(u,v)1), (S(u,v)2). A column portion is formed as an extension from each small region (S(u,v)1), (S(u,v)2) to the projection surface (K). The volume (VM1, VM2) of the column portion is measured for each small region. The measured volumes (VM1, VM2) are accumulated in accordance with the orientation of the normal vector (n) to each small region (S(u,v)1), (S(u,v)2). This method allows the volume (VM) of the target (M) object to be measured easily and with precision even if the shape thereof is complex.
