Reasonable simulation facilitates the advancement of research and reduces experiments on biological tissue. However, the device's clamping motion and sensor interaction with the intestine in the simulation still require further exploration. This article presents a simulation of the artificial anal sphincter's clamping and sensing and its interaction with the intestinal environment using the Simulation Open Framework Architecture (SOFA).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Firstly, the proposed simulation algorithm and its principles in SOFA are analyzed. Secondly, the clamping motion and sensor system of the artificial anal sphincter are simulated. Thirdly, a finite element model of intestine is established based on the properties of intestinal soft tissue. Finally, the in vitro experiments are performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The simulation results indicate that the sensor system of the artificial anal sphincter has good sensing performance during the clamping motion and fecal accumulation process. Experiments have shown that optimal sensory capabilities can be achieved as the posture of the artificial anal sphincter with a roll angle between 20\u00b0 and 40\u00b0. The comparison demonstrates a mean absolute error of 10%\u201320% between simulation and in vitro experimental results for sensor forces, which verifies the effectiveness of the simulation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The proposed novel simulation achieves a more comprehensive interaction between the artificial anal sphincter motion and intestinal environment. This study may provide more effective simulation data for guidance in improving the performance of sensor perception of artificial anal sphincter for further research.<\/jats:p><\/jats:sec>","DOI":"10.1111\/aor.14632","type":"journal-article","created":{"date-parts":[[2023,9,8]],"date-time":"2023-09-08T06:30:01Z","timestamp":1694154601000},"page":"1710-1719","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Simulation of artificial anal sphincter motion and interaction with intestinal environment using <scp>SOFA<\/scp>"],"prefix":"10.1111","volume":"47","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-1300-8474","authenticated-orcid":false,"given":"Changjing","family":"Liu","sequence":"first","affiliation":[{"name":"School of Electronic Information and Electrical Engineering Shanghai Jiao Tong University  Shanghai China"},{"name":"Shanghai Engineering Research Center of Intelligent Addiction Treatment and Rehabilitation  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiwu","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Electronic Information and Electrical Engineering Shanghai Jiao Tong University  Shanghai China"},{"name":"Shanghai Engineering Research Center of Intelligent Addiction Treatment and Rehabilitation  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guozheng","family":"Yan","sequence":"additional","affiliation":[{"name":"School of Electronic Information and Electrical Engineering Shanghai Jiao Tong University  Shanghai China"},{"name":"Shanghai Engineering Research Center of Intelligent Addiction Treatment and Rehabilitation  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pingping","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Electronic Information and Electrical Engineering Shanghai Jiao Tong University  Shanghai China"},{"name":"Shanghai Engineering Research Center of Intelligent Addiction Treatment and Rehabilitation  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6215-2056","authenticated-orcid":false,"given":"Lichao","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Electronic Information and Electrical Engineering Shanghai Jiao Tong University  Shanghai China"},{"name":"Shanghai Engineering Research Center of Intelligent Addiction Treatment and Rehabilitation  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0472-3943","authenticated-orcid":false,"given":"Yelin","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Electronic Information and Electrical Engineering Shanghai Jiao Tong University  Shanghai China"},{"name":"Shanghai Engineering Research Center of Intelligent Addiction Treatment and Rehabilitation  Shanghai China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,9,7]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gtc.2021.10.005"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/aor.14434"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2482-13-45"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1067\/j.cpsurg.2015.02.001"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10151-015-1396-0"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.msea.2017.08.090"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/aor.14177"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/aor.14369"},{"key":"e_1_2_11_10_1","doi-asserted-by":"publisher","DOI":"10.23919\/ChiCC.2018.8483874"},{"key":"e_1_2_11_11_1","doi-asserted-by":"publisher","DOI":"10.1111\/aor.14517"},{"issue":"11","key":"e_1_2_11_12_1","first-page":"133","article-title":"Aas design based on intestinal simulation and reconstruction of defecation perception","volume":"42","author":"Xiao D","year":"2021","journal-title":"Chin J Sci Instrum"},{"key":"e_1_2_11_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.media.2021.101990"},{"key":"e_1_2_11_14_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11548-022-02646-8"},{"key":"e_1_2_11_15_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-030-64610-3_14"},{"key":"e_1_2_11_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cma.2018.10.023"},{"key":"e_1_2_11_17_1","first-page":"283","article-title":"Sofa: a multi\u2010model framework for interactive physical simulation.
