A saline-cooled saw, which has been shown to give good control of the heat generation during bone cutting under laboratory conditions, was tested in in vivo. With a saline flow of 80 mL/min, the maximum cutting temperature in 30 knee prosthetic operations was 32 (25-37) degrees C in the saw blade and respectively 30 (26-35) degrees C and 29 (26-34) degrees C 2 and 3 mm underneath the cut surface. Because the temperature generated by conventional osteotomy equipment may exceed 70 degrees C, the use of our cooled double saw blade during joint replacement prevents heat osteonecrosis.
一种盐水冷却锯，在实验室条件下已被证明在骨切割过程中能很好地控制热量产生，现进行了体内测试。在盐水流速为80毫升/分钟的情况下，在30例膝关节置换手术中，锯片的最高切割温度为32（25 - 37）摄氏度，在切割表面下方2毫米和3毫米处分别为30（26 - 35）摄氏度和29（26 - 34）摄氏度。由于传统截骨设备产生的温度可能超过70摄氏度，在关节置换过程中使用我们的冷却双锯片可防止热骨坏死。
