In usual logarithmic spiral scissors, the cutting input force depends on the position of the blade when the thickness of the cutting material is uniform. We have developed a motion conversion mechanism for logarithmic spiral scissors which equalizes the cutting input force. This paper describes the experimental results of cutting dummy organs. The final objective of this research is whether the proposed scissors can detect tumors when cutting dummy organs. In the ex vivo experiments, we confirmed the maximum cutting input force was 9.0 N when cutting chicken breast as a dummy organ. The experimental results show that the cutting input force of the dummy organ was higher than that of Kent paper (2.9 N).
