Organism Encumbrance of Cardiac Surgeon During Surgery


INTRODUCTION Most everyday activities, performed over a long period leads to performance degradation of skeletal muscles as well as spinal column which is reflected in the reduction of maximum force, reduction of the speed of response, reducing control of the movement etc. Although until now many mathematical models of muscles are developed, very small number takes into account the fatigue, and those models that take into account changes in the characteristics of muscles for extended activities, generally considered tiring under certain conditions. Given that the current models of muscle fatigue under arbitrary conditions of activation and load are very limited, this article presents a new model that includes scale of muscles overload. MATERIAL AND METHODS There are three female cardiac surgeons working performing these surgeries in operating rooms, and their average anthropometric measures for this population is: a) Weight: 62 kg; b) Height: 166 cm. Age: 45 taken in the calculation within the CATIA software, that entity is entitled to 50% of healthy female population that is able to execute these and similar jobs. During the surgery is investigated the two most common positions: position "1" and "2". We wish to emphasize that the experiment or surgical procedure lasted for two positions for five hours, with the position "1" lasted 0.5 hours, and position "2" lasted about 4.5 hours. The additional load arm during surgery is about 1.0 kg. RESULTS The analysis was done in three positions: "Operating position 1", "Operating position 2 ', and each of these positions will be considered in its characteristic segments. These segments are: when the body takes the correct position, but is not yet burdened with external load, then when the surgeon receives the load and the third position when the load is lifted at the end of the position. Calculation of internal energy used on the joints is carried out in the context of software analysis of this model using CATIA R5v19. The proposed model is based on CATIA software model, which consists of visual indicators of the burden on certain parts of the body as well as the forces acting in these parts of the body. CONCLUSION Based on these indicators to define which muscles, as well as that part of the skeletal system is overloaded, what is the position and what needs to be done that specific load be within permitted limits.
