The results show that the precooling time of the probe is shortened significantly with the help of the vapor liquid separator, and decreases with the driven pressure. With the helical coiled wire and the helical mesh, significant thermal Oscillation corresponding the density-wave is observed in the precooling time. The average heat transfer coefficient enhances 1.5 times with the mentioned heat transfer enhancement techniques, and the temperature of the 2.5 min cryoprobe surface can reach -160℃ in 17℃ brine within 10 min.

结果表明：使用了快速预冷汽液分离器后，探针预冷时间大大缩短，并随驱动压力增大而减小；加入螺旋丝和螺旋丝网后，在预冷阶段出现明显的热力振荡，并伴有密度波振荡，平均换热系数为原来的1.5倍，在17℃生理盐水中10min时2.5min探针表面温度最低可达－160℃，大大提高了探针的冷却性能。

Abstractive】 objective to investigate the diagnostic superiorty and therapeutic efficiancy of arthroscopic debridement for the osteoarthritis of the knee.methods 65 cases（74 knee） of senile osteoarthritis of the knee were debrided under arthroscopy with local anesthesia.the procedures included removal of hyperplastic membrance and raw surface of degenerated cartilage,repairing the meniscus,and reshaping of the intercondylar fossa.results 55 cases（67 knee） were followed up for 20 months in average.the pain was relieved and the function of the knee joint was restored in most patients.

目的 探讨关节镜下清理术治疗骨性关节炎的诊断价值及治疗效果。方法对65例（74膝）膝关节骨性关节炎患者采用局麻下行关节清理术，手术清理增生炎性滑膜，清理退变剥脱的软骨及打磨软骨创面，修整损伤半月板，取出关节内游离体、碎骨屑及炎性介质，髁间窝成形术解除撞击及磨损前交叉韧带。结果随诊55例（67膝），随访时间6～42个月，平均20个月，多数患者临床症状消失或者疼痛症状减轻，关节功能明显改善。
