In electrosurgery, the non-stickiness is the major issue affecting the cutting performance of electrosurgical blades. In fact, the electrosurgical blades should have good non-stickiness since it can eliminate tissue build-ups on blade during operations. Normally, the non-stickineess of the blade surface is associated with hydrophobicity of a surface and fabricating low-surface-energy coatings or applying surface roughness can achieve such surface. However, the desirable systematic results of the blade performance were difficult to obtain by using conventional wear or non-sticking tests. Hence, the exact impacts on incision performance by surface treatments are difficult to measure quantitatively. The ability to acquire quantitative data based on actual incisions is important for further in-depth analyses. In this project, a purposely-built test rig will be developed to monitor the resisting force acting on the test specimen during a controlled cut. It is anticipated that the data acquired will facilitate the understanding of the cutting behaviour of the electrosurgical blades in more details, and hence provide useful feedback information to device suitable surface treatments to improve the incision process and non-stickiness of electrosurgical blades. If the project is successful, a new generation of non-sticking electrosurgical blades will be made available for the community.
