Abstract

Surgery is the operation for the treatment due to disease or injury on the patients. Surgery operation involves cutting, abrading, suturing, physically changing body tissues, and organs. The long duration of a surgeon's working hours and sleep deprivation when doing an operation on patients makes the surgeon complicated to stay focus and forces surgeons to learn to manage the effects of physical and mental fatigue on their performance during the operation. The decision to take a break during an operation is often neglected because of concerns about extending the duration of an operation and condition of patient. In this situation, the surgeons are required to work under prolonged hours with significant pressure and often inadequate resources, which cause muscle fatigue and could potentially lead to musculoskeletal disorders (MSD). A product should be developed to assist surgeons in supporting them to avoid muscular injury while undergoing surgery. An innovation of chair is needed to reduce musculoskeletal symptoms among surgeons who are required to sit for a while or a small break after prolonged periods of standing during operation hours. Therefore, this project aims to design and develop a wearable exoskeleton chair ( exo-chair) for the surgeon to provide body support and reduce muscle fatigue. The wearable exo-chair will be designed with a specific ergonomic design that reduces muscle strain at the lower back and leg regions. Although there are wearable chairs that are commercially available, it was not designed to meet a specific requirement for doctors and medical staff. The device will have mechanisms that allow doctors to switch actively between standing, sitting, and walking positions that could be a solution for MSD issues for medical doctors and surgeons when doing operation.
