However, the final impedance value used to control the welding time varies due to differences in tissue size and the welding method during the welding process. This study aims to introduce a new reference indicator not limited by impedance size from dynamic impedance to achieve an adequate weld strength with minimal thermal damage, providing feedback on the tissue welding effect in medical power supplies. End-to-end anastomosis experiments were conducted with porcine small intestine tissue under seven levels of compression pressure. The dynamic impedance changes were analyzed, combined with compression pressure, temperature, moisture, and collagen during welding. The welding process was divided into three stages according to the dynamic impedance, with impedance decreasing in Period \u2160 and impedance increasing in Period \u2162. Period \u2162 was the key to high-strength connections due to water evaporation and collagen reorganization. The dynamic impedance ratio is defined as the final impedance divided by the minimum impedance, and successful welding would be predicted when detecting the dynamic impedance ratio over 4 (n = 70, p &lt; 0.001). Dynamic impedance monitoring can be used as a macroscopic real-time prediction of the anastomosis effect.<\/jats:p>","DOI":"10.3390\/s22114101","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T02:30:06Z","timestamp":1653964206000},"page":"4101","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Dynamic Impedance Analysis of Intestinal Anastomosis during High-Frequency Electric Field Welding Process"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5833-1414","authenticated-orcid":false,"given":"Li","family":"Yin","sequence":"first","affiliation":[{"name":"School of Information Science and Technology, Fudan University, 220 Handan Road, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caihui","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Information Science and Technology, Fudan University, 220 Handan Road, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9060-9722","authenticated-orcid":false,"given":"Jianzhi","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Information Science and Technology, Fudan University, 220 Handan Road, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2384-1606","authenticated-orcid":false,"given":"Hui","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Information Science and Technology, Fudan University, 220 Handan Road, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Qiu","sequence":"additional","affiliation":[{"name":"School of Information Science and Technology, Fudan University, 220 Handan Road, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1115-5222","authenticated-orcid":false,"given":"Hao","family":"Wang","sequence":"additional","affiliation":[{"name":"Academy for Engineering & Technology, Fudan University, 220 Handan Road, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8249-2800","authenticated-orcid":false,"given":"Kefu","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Information Science and Technology, Fudan University, 220 Handan Road, Shanghai 200433, China"},{"name":"Academy for Engineering & Technology, Fudan University, 220 Handan Road, Shanghai 200433, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,28]]},"reference":[{"key":"ref_1","unstructured":"Ferlay, J., Ervik, M., Lam, F., Colombet, M., Mery, L., Pi\u00f1eros, M., Znaor, A., Soerjomataram, I., and Bray, F.
