我科开展冷冻治疗血管瘤、疤痕疙瘩、疣状痣、黑色素痣、雀斑五种疾病共1000例,疗效满意。现小结如下: 一、方法:采用了两种不同的致冷剂,四种方法步骤如下: 1.高压氧气冷冻法:采用上海手术器械一厂生产的氧气冷冻器进行治疗。先将冷冻器接氧气瓶,使冷冻器头致冷(结霜)直接接触皮损进行冷冻,每次2～3分钟,待复温后再冷冻一次,反复2～3次。 2.液氮冷冻治疗机法:应用上海手术器械一厂生产的yDZ～4型液氮冷冻治疗机进行治疗。将液氮灌入冷冻机内,打开治疗开
Our department to carry out cryogenic treatment of hemangiomas, keloids, verrucous nevus, melanoma, freckles five diseases a total of 1000 cases, the effect is satisfactory. Now summarized as follows: First, the method: the use of two different refrigerants, four methods are as follows: 1. High-pressure oxygen freezing method: Shanghai surgical instrument factory oxygen freezer for treatment. Connect the freezer to the oxygen bottle first, then let the freezer head cool (frost) and directly contact with the lesion for freezing, every 2 ~ 3 minutes, then re-freeze and then freeze once, repeat 2 ~ 3 times. 2. Liquid nitrogen cryotherapy machine method: the application of Shanghai surgical equipment factory yDZ ~ 4 liquid nitrogen cryotherapy machine for treatment. Liquid nitrogen into the freezer, open the treatment to open
