Activity movements of cardiac surgeon during classical, endoscopic and robotic surgery on soft tissue

Abstract

It is significant to analyze how long the treatments with the usage of a medical robot, classical or endoscopic instrumentation last. Moreover, it is important to determine the velocity, acceleration and length of the path. This gives an overview of the basic parameters of the operation and enables preoperative planning. The proposed approach makes it possible to evaluate the technical abilities of the surgeon during the suturing operation in an objective manner by specifying quantitative mechanical values, such as: time of the operation, length of the path, and the speed, which are required to achieve proper performance of the procedure.A system of synchronized motion detectors was used in the form of digital cameras with a CCD matrix. The cardiac surgeon’s movements were recorded at a frequency above 30 Hz. The APAS system was applied for kinematic analysis. Mechanical quantities and phenomena were determined based on FDM and analytical geometry.The results section demonstrates the trajectories of various operational activities. Times of classical, endoscopic operations and the usage of a medical robot were also assigned. The results are presented in spatial charts.Information about the duration of individual operations was received. Speeds and joints trajectory provide a view on the cardiac surgeon’s mobility for various types of surgeries.
