The invention discloses an orthopaedic surgical instrument system and method for detaching trial construct assemblies. A surgical instrument system comprising a prosthetic trial component and an orthopaedic surgical instrument is disclosed. The orthopaedic surgical instrument includes a distal tip sized to be received in a passageway of the prosthetic trial component. When the distal tip is positioned in the passageway of the prosthetic trial component and is in an expanded position, the distal tip is configured to engage an inner surface of the prosthetic trial component to secure the prosthetic trial component to the orthopaedic surgical instrument and permit the extraction of the trial component from a patient's bone. A method of use is also disclosed. 本发明题为"用于分离试件构造组件的整形外科器械系统和方法"。本发明公开了种外科器械系统，该外科器械系统包括假体试件部件和整形外科器械。该整形外科器械包括尺寸被设定成接纳在假体试件部件的通道中的远侧末端。当远侧末端定位在假体试件部件的通道中并且处于伸展位置中时，该远侧末端被构造成接合假体试件部件的内表面，以将假体试件部件固定到整形外科器械，并且允许从患者的骨提取试件部件。本发明还公开了种使用方法。
