A surgical bowl set features a first bowl having an internal length (1l) and an internal width (1w), and a second bowl having an external length (2l) and an external width (2w), in which the external length (2l) is close to but less than internal length (1l) in order to permit the second bowl to fit lengthwise within the first bowl while allowing easy extraction of the second bowl from the first bowl, and the external width (2w) is about half or less of internal width (1w).一種手術器械盒組合，其特徵在於：一第一器械盒，其具有一內部長度(1l)及一內部寬度(1w)；及一第二器械盒，其具有一外部長度(2l)及一外部寬度(2w)，其中該外部長度(2l)接近但小於內部長度(1l)以便准許該第二器械盒在長度方向上適配於該第一器械盒內，同時允許易於將該第二器械盒自該第一器械盒抽出，且該外部寬度(2w)約為內部寬度(1w)之一半或更小。
