前言冷冻疗法使机体局部温度降至0℃以下,利用冻结损害达到治疗的目的。此疗法历史悠久,早在一八四五年james,Arnott就曾利用冷盐水治疗蕈样肿瘤,一八八九年White用液态空气治疗红斑狼疮和血管瘤获得成功。直至近二十年,随着低温技术的进步,本疗法才逐渐普及。一九六一年Cooper创造了液态治疗装置,取得了满意的低温效果。目前冷冻疗法已做为新兴学科,又称为冷冻手术(Cryosurgery)见表2。由 Introduction Cryotherapy reduces the body’s local temperature to below 0°C and uses frozen damage for therapeutic purposes. This therapy has a long history. As early as in 1845 james, Arnott used cold saline to treat melanoid tumors, and in 1889 White used liquid air to treat lupus erythematosus and hemangiomas. Until nearly two decades, with the advancement of cryogenic technology, this therapy has gradually become popular. Cooper created a liquid therapy device in 1961 and achieved a satisfactory low temperature effect. Currently cryotherapy has become an emerging discipline, also known as cryosurgery (see Table 2). by
