In light of the scarcity of design data for arthroscopic surgery equipment due to manufacturers’ non-disclosure of research and patents, the aim of the presented work is to study the mechanical stresses experienced by the arthroscopic shaver during soft tissue resection, thus reaching a new design that enhances performance and tool life. The finite element analysis method was used to determine the effect of changing either the tooth angle or rotational speed on stresses experienced by the shaver by creating a model on ANSYS Explicit Dynamics Module. Results were analysed to find that a tooth angle in the range of 55° to 62° would achieve less stresses on the blades, as well as verifying that cutting at 1500 rpm is the most suitable speed for a longer tool life. This research is a part of a project implemented by the NRC and is planned to be verified by experimental work.
