Abstract:

The Thoracic Surgery Database of the Society of Cardiothoracic Surgery in the United Kingdom and Ireland, published in 2011, records a total of 109,388 lung resections or lobes of lung cancer performed between 1980 and 2010, with a significant increase from 2005 onwards. The Korean Statistical Office claims that from January 2010 to December 2014, 25,687 patients underwent 25,921 lung surgeries with cancer. The number of patients operated annually from 2010 to 2014 increased by 45.1%. Every year in Ukraine, lung cancer is diagnosed in 13,000 people, of whom 9,000 die every year. According to the National Registry of Ukraine, 6 out of 10 patients with lung cancer do not live for 1 year from the moment of diagnosis. In 2016, the average incidence of tuberculosis, which is also one of the causes of lung surgery, in Ukraine was approximately 91 people per 100,000. The American Lung Cancer Society estimates, that in the United States of America by 2021 about 235,760 new cases of lung cancer occurred (119,100 in men and 116,660 in women). All of these factors of the increase in lung cancer over the past 30 years have led to an increase in the market capitalization of instruments and services for lung cancer and tuberculosis treatment. In the United States alone, lung diseases cost more than 50 billion US dollars. Purpose: model and study on the static load on a tool for lung welding in SOLIDWORKS. The instrument was modeled based on a bipolar clamp for transmural ablation of the conductive pathways of the heart and electrosurgical bipolar tweezers according to the patent 184388 RU. The tool was modeled for research using surgical steel for its best biophysical characteristics (non-stick, reduced adhesion and charring of tissues) and copper to improve its physical characteristics (electrical and thermal conductivity). As a result, a model of a tool for lung welding was created, a research was conducted on the created tool, found the optimal pressure and displacement while the compression of the parenchyma and bronchi, required force to achieve optimal parameters and safety margin of the tool under this compression.
