Abstract: In a cryosurgical instrument having a dewar and a cap which is threaded onto the dewar when in use, with a main valve portion secured to the cap by threads, the handedness of the threads on the main valve portion are opposite to the handedness of the cap threads, whereby applying thrust through the main valve portion to remove the cap from the dewar will tend to tighten, rather than loosen the main valve portion in the cap.
Abstract translation: 在具有杜瓦瓶和盖帽的冷冻手术器具中，当使用时，其具有螺纹连接到杜瓦瓶上，主阀部分通过螺纹固定到盖上，主阀部分上的螺纹的手性与盖的手性相反 螺纹，其中通过主阀部分施加推力以从杜瓦瓶中移除盖子将倾向于紧固，而不是松开盖中的主阀部分。

Abstract: A liquid cryogen withdrawal device includes a plug (14) for insertion into the neck of a cryogen-containing dewar (10) in gas-tight relationship. A withdrawal tube (17) passes through the plug to conduct liquid from the bottom of the dewar through a sintered bronze filter to a container to be filled with cryogen. Cryogen is stored in the dewar with a loose fitting cap thereon, with no withdrawal device in the dewar. When liquid is desired to be retrieved from the dewar, the withdrawal device is inserted into the dewar; the withdrawal device has a passive heat source (18) disposed at the bottom thereof to cause sufficient boiling of the liquid to create enough pressure to force a suitable amount of liquid from the dewar. The plug may have a handle and a gas pressure relief valve disposed thereon.

Abstract: The cap which is threaded onto the dewar of a cryosurgical instrument has a vent hole therethrough which is normally closed off by a gasket when the cap is secured to the dewar, but which can allow the venting of gaseous cryogen therethrough when the cap is loosened. The threads of the cap have a scalloped region in which the threads have been machined away so as to provide a passage for gaseous cryogen, whereby, when the cap is loosened on the dewar, pressure therein is released by gas escaping either through the hole or through the scalloped region of the threads.
Abstract translation: 螺纹连接到冷冻手术仪器的杜瓦瓶上的帽具有通孔，当盖固定到杜瓦瓶时，通气孔通常由垫圈封闭，但是当帽被松开时，这可以允许气体冷冻剂通过。 盖的螺纹具有扇形区域，其中已经将螺纹加工掉，以便提供用于气态冷冻剂的通道，由此当帽在杜瓦瓶上松开时，其中的压力通过气体逸出而释放， 通过扇形区域的线程。
