Of two types of systems for cryogenic support (SCS) of surgical instruments made with open and closed contours those of the discharge type meet to a greater extent basic requirements on the SCS as concerns destruction of extensive areas of the biological tissue. These SCS permit it more readily to withstand optimal conditions of cooling, can secure better reliability in performing operations, offer greater possibilities for unification of parts in packing up the set and for covering a wider range of operations. In cases when it is important to provide for self-containment and a longer period of continuous operation the application of the SCS with a closed contour is more advisable.
在两种用于外科器械低温支持（SCS）的系统中，即轮廓开放和封闭的系统，排放型系统在生物组织大面积破坏方面，在更大程度上满足了对SCS的基本要求。这些SCS更易于承受最佳冷却条件，在手术操作中能确保更好的可靠性，在包装组件时部件统一以及涵盖更广泛手术范围方面提供了更大可能性。在需要保证设备自给自足和更长连续运行时间的情况下，应用轮廓封闭的SCS更为可取。
