摘要： A tension meter for measuring the degree of tension between bones has a grip portion, a tension meter body mounted to the grip portion, and a torque setting device rotatably connected through a torque shaft to the tension meter body. The tension meter body includes a body portion, a fixed arm extending from one end of the body portion, and a movable arm mounted on the body portion so as to be movable away therefrom. The movable arm is located in opposed relationship to the fixed arm. The movable arm is provided with a gear portion meshing the torque shaft. The torque setting device is provided with a torque limiter for limiting relative displacement of the movable arm in relation to the fixed arm according to a force to be applied between the fixed arm and the movable arm. Use of the tension meter produces quantitative data which makes it possible to carry out surgical operations with reproducible results because they do not rely only upon the surgeon's senses.

摘要翻译： 用于测量骨骼之间的张力的张力计具有握持部分，安装在把手部分上的张力计体，以及通过转矩轴可转动地连接到张力计主体的扭矩设定装置。 张力计主体包括主体部分，从主体部分的一端延伸的固定臂以及安装在主体部分上以便可移动的可动臂。 可动臂与固定臂相对置。 可动臂设有与转矩轴啮合的齿轮部。 扭矩设定装置设置有扭矩限制器，用于根据施加在固定臂和可动臂之间的力来限制可动臂相对于固定臂的相对位移。 使用张力计产生定量数据，使得可以进行具有可重复结果的外科手术，因为它们不仅仅依赖于外科医生的感觉。
