However, the body structure is too simple, resulting in the utilization rate of oxygen being usually low. In this work, we reported a deformable rigid bronchoscope (named Oribron) by adding a Waterbomb origami structure to the body. The Waterbomb\u2019s backbone is made of films, and the pneumatic actuators are placed inside it to achieve rapid deformation at low pressure. Experiments showed that Waterbomb has a unique deformation mechanism, which can transform from a small-diameter configuration (#1) to a large-diameter configuration (#2), showing excellent radial support capability. When Oribron entered or left the trachea, the Waterbomb remained in #1. When Oribron is working, the Waterbomb transforms from #1 to #2. Since #2 reduces the gap between the bronchoscope and the tracheal wall, it effectively slows down the rate of oxygen loss, thus promoting the absorption of oxygen by the patient. Therefore, we believe that this work will provide a new strategy for the integrated development of origami and medical devices.<\/jats:p>","DOI":"10.3390\/mi14040822","type":"journal-article","created":{"date-parts":[[2023,4,7]],"date-time":"2023-04-07T04:08:03Z","timestamp":1680840483000},"page":"822","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Oribron: An Origami-Inspired Deformable Rigid Bronchoscope for Radial Support"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9508-8495","authenticated-orcid":false,"given":"Junjie","family":"Su","sequence":"first","affiliation":[{"name":"School of Biomedical Engineering, Anhui Medical University, Hefei 230009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yangyang","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering, Anhui Medical University, Hefei 230009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liang","family":"Cheng","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering, Anhui Medical University, Hefei 230009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7960-555X","authenticated-orcid":false,"given":"Ling","family":"Zhu","sequence":"additional","affiliation":[{"name":"Anhui Institute of Optics and Fine Mechanics, Hefei Institutes of Physical Science, Chinese Academy of Sciences, Hefei 230031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3529-0277","authenticated-orcid":false,"given":"Runhuai","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering, Anhui Medical University, Hefei 230009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1847-4920","authenticated-orcid":false,"given":"Fuzhou","family":"Niu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Suzhou University of Science and Technology, Suzhou 215009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ke","family":"Yang","sequence":"additional","affiliation":[{"name":"Anhui Institute of Optics and Fine Mechanics, Hefei Institutes of Physical Science, Chinese Academy of Sciences, Hefei 230031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuping","family":"Duan","sequence":"additional","affiliation":[{"name":"School of Biomedical Engineering, Anhui Medical University, Hefei 230009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"674","DOI":"10.1055\/s-0038-1676647","article-title":"Rigid Bronchoscopy","volume":"39","author":"Peralta","year":"2019","journal-title":"Semin.
