Therefore liquid CO_2 avoids gas-solid multiphase flow, and supplies continuous low temperature gas for cryoprobe. Experimental results show that the 2-dimension temperature distribution for the first time, it includes:(1) The cooling velocity and freezing zone increases along the flux up at certain size of the cryoprobe in the same biological tissue.(2) As the diameter of cryoprobe increases, the temperature will descend faster, freezing zone will be broader obviously, and ice ball become larger. Until it arrives heat balance, the temperature keeps invariability.(3) Single freezing-thaw results in biggish mechanical injury already for loosen tissue such as pork liver; Successive freeze-thaw circle could quicken freezing and thaw velocity for compact tissue, and it has proved the more mechanical injury of successive freeze-thaw circle than the single freezing-thaw treatment.

文中首次对生物组织进行了二维温度场分布实验研究,得出:(1)当刀头大小一定,对同一组织冷冻时,流量越大,降温速度越快,降温影响区域越大;(2)随着冷刀直径的增加,降温速度随着增加;温度影响区域明显增大;冰球直径也随着增大,热量平衡后温度几乎不随时间变化;(3)对于结构疏松组织比如猪肺脏,单次冻融对组织已造成较大的机械破损;对于结构较致密组织,多次反复冻融可以使降温和复温速率增加,单次冻融的热应力造成的机械破损较小,多次冻融后造成的机械破损比单次冻融所造成的机械破损大;(4)直喷式刀头比导热式节能约15%。
