Abstract

This paper describes the development of a surgical tool with a single strain area for measuring biaxial cutting forces. For measuring bending and compression forces in a single strain area, the strain area needs to be sensitive to both bending and compression. In general, the bending strain is easier to measure compared with the compressive strain. In this paper, an oval shape is designed in the strain area to obtain both forces. With the proposed shape, two axes forces could be measured. However, the residual strain in the direction of bending remained. Therefore, a spring is inserted in the tool to compensate for the residual strain. Consequently, the residual strain can be canceled out, and the surgical instrument with a single strain area for measuring biaxial cutting forces can be developed. The cutting experiment is carried out to demonstrate the validity of the developed instrument in a more practical situation. In the experiment, Tofu is cut with different cutting angles. The cutting experiment demonstrates the validity of the developed instrument.
