The Versius Surgical System\u00ae (CMR Surgical, Cambridge, United Kingdom) was developed to optimize the surgical experience and improve patient outcomes.  Aims:  This study aims to evaluate system applicability and its positioning and configuration within the operating room, using a preclinical in vitro model for supraumbilical midline closure.  Methods:  The study was conducted at the Teaching and Research Laboratory of Universidade de S\u00e3o Paulo University Hospital, using an in vitro synthetic latex abdominal wall model. For supraumbilical midline closure, the instrument units were positioned laterally (right and left), near the hypochondria, and the visualization unit was placed on the right side at the level of the pelvis. Surgical access points were created to allow for continuous suturing of an approximately 10 cm incision: one 10 mm suprapubic trocar and two 5 mm trocars placed bilaterally along the anterior axillary line at the level of the umbilicus.  Results:  The initial positioning of the robotic units allowed for an ergonomic configuration suitable for suturing. The continuous supraumbilical suture was performed using 2-0 barbed non-absorbable suture material, two needle drivers, and laparoscopic scissors, with stitch intervals of approximately 1 cm and moderate tension. Adequate closure of the hernia defect was achieved. The in vitro laboratory training phase totaled 20 hours. During this period, continuous suture was performed five times, with completion times ranging from 45 to 25 minutes.  Conclusions:  The Versius Surgical System\u00ae demonstrated full operational capability for supraumbilical midline closure in an inanimate model, without complications. Strategic positioning of the robotic arms allowed for adequate access and satisfactory docking times. Mastering the spatial positioning of the units is essential for optimizing the operative field and reducing non-productive time.<\/jats:p>","DOI":"10.1590\/0102-672020260000052e1981","type":"journal-article","created":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T10:38:01Z","timestamp":1791196681000},"source":"Crossref","is-referenced-by-count":0,"title":["Usability of an independent arm modular robotic system in abdominal wall surgery: supraumbilical midline closure"],"prefix":"10.1590","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-9333-4037","authenticated-orcid":false,"given":"Bernardo Munoz","family":"SILES","sequence":"first","affiliation":[{"name":"Universidade de S\u00e3o Paulo","place":["S\u00e3o Paulo, SP, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8700-0067","authenticated-orcid":false,"given":"Ricardo Zugaib","family":"ABDALLA","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo","place":["S\u00e3o Paulo, SP, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1711-7347","authenticated-orcid":false,"given":"Ulysses","family":"RIBEIRO JUNIOR","sequence":"additional","affiliation":[{"name":"Universidade de S\u00e3o Paulo","place":["S\u00e3o Paulo, SP, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2026]]},"reference":[{"issue":"1","key":"ref1","doi-asserted-by":"crossref","first-page":"695","DOI":"10.1007\/s11701-025-02881-6","article-title":"Prospective study of a structured robotic surgery training program in a public cancer hospital in Brazil","volume":"19","author":"Abdalla RZ","year":"2025","journal-title":"J Robot Surg"},{"issue":"3","key":"ref2","doi-asserted-by":"crossref","DOI":"10.1093\/ejcts\/ezac178","article-title":"Preclinical evaluation of Versius, an innovative device for use in robot-assisted thoracic surgery","volume":"62","author":"Aresu G","year":"2022","journal-title":"Eur J Cardiothorac Surg"},{"issue":"1","key":"ref3","first-page":"99","article-title":"Robotic-assisted compared with laparoscopic incisional hernia repair following oncologic surgery: short- and long-term outcomes of a randomized controlled trial","volume":"17","author":"Costa TN","year":"2023","journal-title":"J Robot Surg"},{"issue":"2","key":"ref4","doi-asserted-by":"crossref","first-page":"105","DOI":"10.11622\/smedj.2022005","article-title":"Elective incisional hernia repair: lower risk of postoperative wound infection with laparoscopic versus open repair","volume":"64","author":"Goh SSN","year":"2023","journal-title":"Singapore Med J"},{"issue":"1","key":"ref5","article-title":"Usability assessment of Versius, a new robot-assisted surgical device for use in minimal access surgery","volume":"2","author":"Haig F","year":"2020","journal-title":"BMJ Surg Interv Health Technol"},{"key":"ref6","series-title":"The da Vinci Surgical System","year":"2024"},{"issue":"1","key":"ref7","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1097\/SLA.0000000000005410","article-title":"An early prospective clinical study to evaluate the safety and performance of the versius surgical system in robot-assisted cholecystectomy","volume":"277","author":"Kelkar DS","year":"2023","journal-title":"Ann Surg"},{"issue":"4","key":"ref8","doi-asserted-by":"crossref","first-page":"e903","DOI":"10.1097\/SLA.0000000000005871","article-title":"Safe implementation of a next-generation surgical robot: first analysis of 2,083 cases in the versius surgical registry","volume":"278","author":"Soumpasis I","year":"2023","journal-title":"Ann Surg"},{"key":"ref9","doi-asserted-by":"crossref","DOI":"10.1590\/0102-67202025000039e1908","article-title":"Global strategies for the diffusion of robotic surgery","volume":"38","author":"Tustumi F","year":"2025","journal-title":"Arq Bras Cir Dig"},{"issue":"4","key":"ref10","article-title":"A systematic review of the true benefit of robotic surgery: Ergonomics","volume":"16","author":"Wee IJY","year":"2020","journal-title":"Int J Med Robot"}],"container-title":["ABCD.
