Stress Analysis on the Base of Surgeon’s Chair: Frame and Truss Perspective
摘要
Musculoskeletal disorders frequently occur in various types of work, including laparoscopic surgeons. The surgeon profession is classified as a high-risk occupation and may have musculoskeletal disorders. Surgeons who suffer from these disorders experience illnesses ranging from mild to severe because the muscles often receive long-term static loads. These causes can be prevented when working in a seated position. In this work, the investigation being conducted is to design a chair as a surgeon's aid that consists of a base platform, seat height adjustment mechanism, seat cushion, backrest, and handrest. In this paper, a rectangular platform is analyzed using a finite element model. The analysis results by considering the structure as a truss produce the largest stress of 34 MPa compared the structure as a frame of 30 MPa. These two approaches lead to the conclusion that the structure computed as a truss is more secure than the analysis of the structure as a frame.
